                          ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISER
- --------------------------------------------------------------------------------


                                                               November 30, 1999


Dear Shareholder:

     After easing monetary policy three times during the fourth quarter of 1998,
the Federal  Reserve  reversed its trend by raising the Fed funds target rate 75
basis  points (to 5.50%) over the course of 1999 in response to robust GDP,  low
unemployment and rising equity prices.  U.S. Treasury yields rose  significantly
during the past twelve  months,  with the yield of the 30-year  Treasury  rising
above 6.00% for the first time since May 1998.

     Despite the rise in Treasury  yields,  continued strong economic growth may
spur the  Federal  Reserve to  proactively  fight  perceived  inflation  through
continued  monetary  policy  tightening  in 2000.  Until the  inflation  picture
becomes  clearer,  we  expect  interest  rates to  remain  largely  range-bound.
Accordingly,  we will  continue  to seek  the  most  attractive  relative  value
opportunities  and utilize our proprietary  risk management  systems to help the
Trust to achieve its investment objectives.

     This  report  contains  a summary  of market  conditions  during the annual
period and a review of portfolio  strategy by your Trust's  managers in addition
to the Trust's audited financial statements and a detailed portfolio list of the
portfolio's  holdings.  Continued  thanks for your  confidence in BlackRock.  We
appreciate the opportunity to help you achieve your long-term investment goals.

Sincerely,


/s/ Laurence D. Fink                                  /s/ Ralph L. Schlosstein

                                                               November 30, 1999

Dear Shareholder:

     We are pleased to present the annual report for The BlackRock  Income Trust
Inc.  ("the Trust") for the fiscal year ended October 31, 1999. We would like to
take this  opportunity  to review the  Trust's  stock  price and net asset value
(NAV)  performance,  summarize market  developments and discuss recent portfolio
management activity.

     The Trust is a diversified,  actively  managed  closed-end  bond fund whose
shares are traded on the New York Stock  Exchange  under the symbol  "BKT".  The
Trust's  investment  objective is to provide high current income consistent with
the  preservation  of  capital.  The Trust  seeks this  objective  by  investing
primarily in mortgage-backed securities backed by U.S. Government agencies (such
as  Fannie  Mae,  Freddie  Mac or  Ginnie  Mae) and,  to a lesser  extent,  U.S.
Government   securities,    asset-backed   securities   and   privately   issued
mortgage-backed securities. At least 85% of the Trust's assets must be issued or
guaranteed  by the U.S.  government or its agencies or rated "AAA" by Standard &
Poor's or "Aaa" Moody's (up to 5% can be unrated and deemed by the Adviser to be
of equivalent  credit quality);  the remaining 15% of the Trust's assets must be
rated at least "AA" by Standard & Poor's or "Aa" by Moody's at time of purchase.

The table below  summarizes  the  performance of the Trust's stock price and NAV
over the past twelve months:

THE FIXED INCOME MARKETS

     The U.S.  economy  sustained its growth during the past twelve  months,  as
U.S.  exports and  manufacturing  continued to rebound.  Additionally,  consumer
strength remains an important contributor to economic growth as low unemployment
and rising incomes fuel domestic  demand.  After  lowering  interest rates three
times in the second half of 1998, and despite inflation  concerns as measured by
CPI  and  PPI  remaining  relatively  benign,  the  Federal  Reserve  adopted  a
tightening  bias and raised its target for the Federal  funds rate from 4.75% to
5.50%  between June and November  1999. In a statement  accompanying  the latest
tightening  on November 16, it was  indicated  that the Fed believes that growth
"continues in excess of the economy's growth potential";  nevertheless,  the Fed
reversed their tightening stance by adopting a neutral bias.

     After a brief rally in late 1998,  Treasury yields rose dramatically during
1999. Over the period,  the yield of the 30-year Treasury increased by 100 basis
points,  closing at 6.16% on October 31. Bond  prices,  which move  inversely to
their yields,  were punished by the constant  threat of inflation in response to
the strong  economic  data and the  market's  uncertainty  over the Fed's policy
throughout the year.  Recently,  a weaker dollar,  higher  commodity  prices and
strong gains in the U.S.  and European  equity  markets have  depressed  overall
demand for fixed income securities.

     Mortgage security  performance  significantly  outpaced both Treasuries and
the broader  domestic  fixed  income  markets  during the period,  as the LEHMAN
BROTHERS  MORTGAGE  INDEX  posted a 3.00%  total  return  versus  -0.82% for the
MERRILL  LYNCH U.S.  TREASURY  MASTER  INDEX and 0.53% for the  LEHMAN  BROTHERS
AGGREGATE INDEX. Higher interest rates throughout the period helped to alleviate
prepayment  fears and pushed  mortgage  rates  above 8% for the first time since
1997.  Additionally,  new  mortgage  issuance  declined  in  response  to  lower
refinancing  activity  across all  coupons and  vintages,  providing a favorable
technical environment for mortgages.

THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY

     BlackRock actively manages the Trust's portfolio  holdings  consistent with
BlackRock's overall market outlook and the


                                       2

Trust's investment objectives. The Trust is managed to maintain an interest rate
sensitivity (or duration)  approximately 1.5 times the SALOMON BROTHERS MORTGAGE
INDEX; this means that the portfolio's NAV will change similarly to the price of
the Index given a change in interest  rates.  The following  chart  compares the
Trust's current and October 31, 1998 asset composition:

- --------------------------------------------------------------------------------

     The Trust  continued to emphasize  yield during the period,  maintaining  a
significant  allocation  to  IOs  and  mortgage  pass-through  allocations.   In
particular,  pass-throughs  were  attractively  priced  relative  to other fixed
income  alternatives  during the period and provided the Trust an opportunity to
increase  its  overall  liquidity.  To fund  these  purchases,  the  Trust  took
advantage of the strong performance of the commercial  mortgage-backed sector by
paring its exposure as yield spreads  tightened  during the year.  Additionally,
the Trust sold some of its CMO and adjustable-rate mortgage holdings into strong
bids,  which aided  performance  as well as reduced the  Trust's  interest  rate
exposure.

     We look  forward to  continuing  to manage  the Trust to  benefit  from the
opportunities  available to investors in the fixed income  markets as well as to
maintain the Trust's ability to meet its investment objectives. We thank you for
your  investment in the BlackRock  Income Trust Inc. Please feel free to contact

THE BLACKROCK INCOME TRUST INC.
NOTES TO FINANCIAL STATEMENTS

NOTE 1. ORGANIZATION        The  BlackRock  Income Trust Inc. (the  "Trust"),  a
& ACCOUNTING                Maryland  corporation,  is a diversified  closed-end
POLICIES                    management   in-vestment   company.  The  investment
                            objective  of the Trust is to achieve  high  monthly
income consistent with  preservation of capital.  The ability of issuers of debt
securities  held by the  Trust to meet  their  obligations  may be  affected  by
economic  developments  in a specific  industry or region.  No assurance  can be
given that the Trust's investment objective will be achieved.

       The following is a summary of significant accounting policies followed by
the Trust.

SECURITIES VALUATION:  The Trust values mortgage-backed,  asset-backed and other
debt  securities,  interest rate swaps,  caps,  floors and  non-exchange  traded
options on the basis of current market quotations provided by dealers or pricing
services approved by the Trust's Board of Directors. In determining the value of
a particular security, pricing services may use certain information with respect
to transactions in such securities, quotations from dealers, market transactions
in comparable  securities,  various relationships observed in the market between
securities, and calculated yield measures based on valuation technology commonly
employed in the market for such securities.  Exchange-traded  options are valued
at their last sales price as of the close of options  trading on the  applicable
exchanges.  In the absence of a last sale,  options are valued at the average of
the quoted bid and asked prices as of the close of business.  A futures contract
is valued at the last sale price as of the close of the commodities  exchange on
which it trades unless the Trust's Board of Directors determines that such price
does not  reflect  its fair  value,  in which case it will be valued at its fair
value as determined by the Trust's Board of Directors.  Any  securities or other
assets for which such current market  quotations  are not readily  available are
valued at fair value as determined in good faith under procedures established by
and under the general  supervision  and  responsibility  of the Trust's Board of
Directors.

     Short-term  securities  which  mature  in 60  days or less  are  valued  at
amortized  cost,  if their term to maturity  from date of purchase is 60 days or
less.  Short-term  securities with a term to maturity  greater than 60 days from
the date of purchase are valued at current market  quotations  until maturity or
disposition.

     In  connection  with  transactions  in repurchase  agreements,  the Trust's
custodian takes possession of the underlying collateral securities, the value of
which at least  equals  the  principal  amount  of the  repurchase  transaction,
including  accrued  interest.  To the  extent  that any  repurchase  transaction
exceeds one business day, the value of the collateral is  marked-to-market  on a
daily basis to ensure the adequacy of the collateral. If the seller defaults and
the value of the collateral declines or if bankruptcy  proceedings are commenced
with respect to the seller of the security, realization of the collateral by the
Trust may be delayed or limited.

OPTION  SELLING/PURCHASING:  When the Trust  sells or  purchases  an option,  an
amount  equal to the  premium  received  or paid by the Trust is  recorded  as a
liability or an asset and is  subsequently  adjusted to the current market value
of the option  written or purchased.  Premiums  received or paid from writing or
purchasing  options  which  expire  unexercised  are treated by the Trust on the
expiration date as realized gains or losses.  The difference between the premium
and the  amount  paid or  received  on  effecting  a  closing  purchase  or sale
transaction, including brokerage commissions, is also treated as a realized gain
or loss. If an option is exercised, the premium paid or received is added to the
proceeds from the sale or cost of the purchase in determining  whether the Trust
has realized a gain or a loss on investment  transactions.  The Trust, as writer
of an option, may have no control over whether the underlying  securities may be
sold  (call) or  purchased  (put) and as a result  bears the  market  risk of an
unfavorable change in the price of the security underlying the written option.

    Options,  when used by the Trust,  help in maintaining a targeted  duration.
Duration is a measure of the price  sensitivity  of a security or a portfolio to
relative changes in interest rates. For instance, a duration of "one" means that
a portfolio's or a security's price would be expected to change by approximately
one percent  with a one percent  change in interest  rates,  while a duration of
five  would  imply  that the price  would  move  approximately  five  percent in
relation to a one percent change in interest rates.

    Option selling and  purchasing is used by the Trust to  effectively  "hedge"
positions, or collections of positions, so that changes in interest rates do not
change the duration of the portfolio  unexpectedly.  In general,  the Trust uses
options to hedge a long or short position or an overall portfolio that is longer
or shorter than the benchmark security. A call option gives the purchaser of the
option the right (but not  obligation)  to buy, and obligates the seller to sell
(when the option is exercised), the underlying position at the exercise price at
any time or at a specified time during the option period. A put option gives the
holder the right to sell and obligates the writer to buy the underlying position
at the  exercise  price at any time or at a  specified  time  during  the option
period. Put options can be purchased to effec-


                                       14

tively hedge a position or a portfolio  against price declines if a portfolio is
long. In the same sense, call options can be purchased to hedge a portfolio that
is shorter than its benchmark against price changes. The Trust can also sell (or
write) covered call options and put options to hedge portfolio positions.

     The main risk that is associated with purchasing options is that the option
expires without being exercised.  In this case, the option expires worthless and
the premium paid for the option is considered the loss. The risk associated with
writing call options is that the Trust may forego the  opportunity  for a profit
if the  market  value of the  underlying  position  increases  and the option is
exercised. The risk in writing put options is that the Trust may incur a loss if
the  market  value  of the  underlying  position  decreases  and the  option  is
exercised.  In addition,  as with futures  contracts,  the Trust risks not being
able to enter into a closing transaction for the written option as the result of
an illiquid market.

INTEREST  RATE  SWAPS:  In a simple  interest  rate swap,  one  investor  pays a
floating  rate of interest on a notional  principal  amount and receives a fixed
rate of interest on the same notional principal amount for a specified period of
time.  Alternatively,  an  investor  may pay a fixed rate and receive a floating
rate.  Rate swaps are efficient as  asset/liability  management  tools.  In more
complex  swaps,  the notional  principal  amount may decline (or amortize)  over
time.

     During  the  term  of the  swap,  changes  in the  value  of the  swap  are
recognized as unrealized gains or losses by  "marking-to-market"  to reflect the
market value of the swap.  When the swap is terminated,  the Trust will record a
realized gain or loss equal to the difference between the proceeds from (or cost
of) the closing transaction and the Trust's basis in the contract, if any.

     The Trust is exposed to credit loss in the event of  non-performance by the
other party to the swap. However,  the Trust closely monitors swaps and does not
anticipate non-performance by any counterparty.

SWAP  OPTIONS:  Swap  options are similar to options on  securities  except that
instead of selling or purchasing the right to buy or sell a security, the writer
or  purchaser of the swap option is granting or buying the right to enter into a
previously  agreed  upon  interest  rate swap  agreement  at any time before the
expiration of the option.  Premiums  received or paid from writing or purchasing
options are recorded as liabilities or assets and are  subsequently  adjusted to
the current market value of the option written or purchased.  Premiums  received
or paid from writing or purchasing options which expires unexercised are treated
by the Trust on the expiration date as realized gains or losses.  The difference
between the  premium  and the amount  paid or  received  on  effecting a closing
purchase or sale transaction, including brokerage commission, is also treated as
a realized gain or loss. If an option is exercised, the premium paid or received
is added to the proceeds  from the sale or cost of the  purchase in  determining
whether the Trust has realized a gain or loss on investment transactions.

     The main risk that is associated  with  purchasing swap options is that the
swap option expires  without being  exercised.  In this case, the option expires
worthless and the premium paid for the swap option is considered  the loss.  The
main risk that is  associated  with the  writing of a swap  option is the market
risk of an unfavorable  change in the value of the interest rate swap underlying
the written swap option.

     Swap options may be used by the Trust to manage the duration of the Trust's
portfolio in a manner similar to more generic options described above.

FINANCIAL  FUTURES  CONTRACTS:  A futures  contract is an agreement  between two
parties to buy and sell a financial instrument for a set price on a future date.
Initial margin deposits are made upon entering into futures contracts and can be
either  cash or  securities.  During the period the  futures  contract  is open,
changes in the value of the  contract  are  recognized  as  unrealized  gains or
losses by  "marking-to-market"  on a daily basis to reflect the market  value of
the contract at the end of each day's  trading.  Variation  margin  payments are
made or  received,  depending  upon  whether  unrealized  gains  or  losses  are
incurred. When the contract is closed, the Trust records a realized gain or loss
equal to the  difference  between  the  proceeds  from (or cost of) the  closing
transaction and the Trust's basis in the contract.

     Financial futures contracts,  when used by the Trust, help in maintaining a
targeted  duration.  Futures  contracts  can be sold to  effectively  shorten an
otherwise longer duration portfolio. In the same sense, futures contracts can be
purchased  to lengthen a portfolio  that is shorter  than its  duration  target.
Thus, by buying or selling futures contracts,  the Trust can effectively "hedge"
positions  so that  changes in interest  rates do not change the duration of the
portfolio unexpectedly.

     The Trust may  invest in  financial  futures  contracts  primarily  for the
purpose of hedging its existing  portfolio  securities or  securities  the Trust
intends  to  purchase  against  fluctuations  in  value  caused  by  changes  in
prevailing market interest rates.  Should interest rates move unexpectedly,  the
Trust  may  not  achieve  the  anticipated  benefits  of the  financial  futures
contracts and may realize a loss. The use of futures  transactions  involves the
risk of imperfect  correlation  in movements in the price of futures  contracts,
interest rates and the underlying  hedged assets.  The Trust is also at the risk
of not being


                                       15
<PAGE>

able to enter into a closing  transaction for the futures contract because of an
illiquid  secondary  market.  In addition,  since futures are used to shorten or
lengthen a  portfolio's  duration,  there is a risk that the  portfolio may have
temporarily  performed  better  without the hedge or that the Trust may lose the
opportunity  to  realize  appreciation  in the  market  price of the  underlying
positions.

SHORT SALES: The Trust may make short sales of securities as a method of hedging
potential  price declines in similar  securities  owned.  When the Trust makes a
short  sale,  it may  borrow  the  security  sold  short and  deliver  it to the
broker-dealer  through  which  it made  the  short  sale as  collateral  for its
obligation  to deliver the security upon  conclusion of the sale.  The Trust may
have to pay a fee to borrow the  particular  securities  and may be obligated to
pay over any payments received on such borrowed  securities.  A gain, limited to
the price at which the Trust sold the security short, or a loss, unlimited as to
dollar amount,  will be recognized  upon the  termination of a short sale if the
market price is greater or less than the proceeds originally received.

SECURITIES  LENDING:  The Trust may lend its  portfolio  securities to qualified
institutions.  The loans are secured by collateral at least equal, at all times,
to the market  value of the  securities  loaned.  The Trust may bear the risk of
delay in recovery of, or even loss of rights in, the  securities  loaned  should
the borrower of the securities fail financially. The Trust receives compensation
for lending its  securities in the form of interest on the loan.  The Trust also
continues to receive interest on the securities  loaned, and any gain or loss in
the market price of the securities  loaned that may occur during the term of the
loan will be for the account of the Trust.

INTEREST  RATE CAPS:  Interest  rate caps are  similar to  interest  rate swaps,
except  that one party  agrees to pay a fee,  while  the  other  party  pays the
excess, if any, of a floating rate over a specified fixed or floating rate.

     Interest  rate caps are intended to both manage the duration of the Trust's
portfolio and its exposure to changes in short term rates.  Owning interest rate
caps reduces the  portfolio's  duration,  making it less sensitive to changes in
interest rates from a market value  perspective.  The effect on income  involves
protection from rising short term rates,  which the Trust experiences  primarily
in the form of leverage.

     The Trust is exposed to credit loss in the event of  non-performance by the
other party to the interest  rate cap.  However,  the Trust does not  anticipate
non-performance by any counterparty.

     Transactions fees paid or received by the Trust are recognized as assets or
liabilities  and amortized or accreted into interest  expense or income over the
life of the interest rate cap. The asset or liability is  subsequently  adjusted
to the current market value of the interest rate cap purchased or sold.  Changes
in the value of the interest rate cap are  recognized  as  unrealized  gains and
losses.

INTEREST  RATE FLOORS:  Interest rate floors are similar to interest rate swaps,
except  that one party  agrees to pay a fee,  while  the  other  party  pays the
excess, if any, of a floating rate under a specified fixed or floating rate.

     Interest  rate floors are used by the Trust to both manage the  duration of
the portfolio and its exposure to changes in short-term interest rates.  Selling
interest rate floors reduces the portfolio's duration,  making it less sensitive
to changes  in  interest  rates from a market  value  perspective.  The  Trust's
leverage  provides  extra income in a period of falling  rates.  Selling  floors
reduces some of that advantage by partially monetizing it as an up front payment
which the Trust receives.

     The Trust is exposed to credit loss in the event of  non-performance by the
other party to the interest rate floor.  However,  the Trust does not anticipate
non-performance by any counterparty.

     Transactions fees paid or received by the Trust are recognized as assets or
liabilities  and amortized or accreted into interest  expense or income over the
life of the interest rate floor. The asset or liability is subsequently adjusted
to the  current  market  value of the  interest  rate floor  purchased  or sold.
Changes in the value of the interest  rate floor are  recognized  as  unrealized
gains and losses.

SECURITIES  TRANSACTIONS AND NET INVESTMENT INCOME:  Securities transactions are
recorded  on the trade  date.  Realized  and  unrealized  gains and  losses  are
calculated  on the  identified  cost basis.  Interest  income is recorded on the
accrual  basis  and  the  Trust  accretes  discount  and  amortizes  premium  on
securities  purchased  using the interest  method.  Expenses are recorded on the
accrual basis which may require the use of certain estimates by management.

TAXES: It is the Trust's  intention to continue to meet the  requirements of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  substantially all of its taxable income to shareholders.  Therefore,
no federal income tax provision is required.

DIVIDENDS  AND  DISTRIBUTIONS:   The  Trust  declares  and  pays  dividends  and
distributions  monthly,  first from net  investment  income,  then from realized
short-term capital gains and other sources, if necessary.  Net long-term capital
gains, if any, in


                                       16
<PAGE>

excess of loss  carryforwards  are distributed at least annually.  Dividends and
distributions are recorded on the ex-dividend date.

     Income  distributions  and capital gain  distributions  are  determined  in
accordance with income tax regulations which may differ from generally  accepted
accounting principles.

ESTIMATES:  The preparation of financial statements in conformity with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.


NOTE 2. AGREEMENTS   The  Trust  has  an  Investment   Advisory  Agreement  with
                     BlackRock  Financial  Management,  Inc. (the "Adviser"),  a
wholly-owned  subsidiary of BlackRock  Advisors,  Inc.,  which is a wholly-owned
subsidiary  of  BlackRock,  Inc.,  which in turn is an  indirect  majority-owned
subsidiary  of PNC Bank Corp.  The Trust has an  Administration  Agreement  with
Prudential  Investments Fund Management LLC ("PIFM"), a wholly-owned  subsidiary
of The Prudential Insurance Co. of America.

     The  investment  fee paid to the  Adviser is  computed  weekly and  payable
monthly at an annual rate of 0.65% of the Trust's average weekly net assets. The
administration  fee paid to PIFM is also computed  weekly and payable monthly at
an annual rate of 0.20% of the first $500 million of the Trust's  average weekly
net assets and 0.15% of any excess.

     Pursuant to the agreements,  the Adviser provides continuous supervision of
the  investment  portfolio and pays the  compensation  of officers of the Trust.
PIFM pays occupancy and certain  clerical and accounting costs of the Trust. The
Trust bears all other costs and expenses.

NOTE 3. PORTFOLIO    Purchases  and sales of investment  securities,  other than
SECURITIES           short-term investments and dollar rolls, for the year ended
                     October 31, 1999 aggregated  $967,030,380 and $879,274,684,
                     respectively.

     The Trust may invest  without  limit in  securities  which are not  readily
marketable,  including  those  which  are  restricted  as to  disposition  under
securities law ("restricted securities") although the Trust does not expect that
such investments will generally exceed 25% of its portfolio  assets.  At October
31, 1999,  the Trust held 0.24% of its portfolio  assets in illiquid  securities
all of which were securities restricted as to resale.

     The Trust may from time to time  purchase in the secondary  market  certain
mortgage  pass-through  securities  packaged or master  serviced by PNC Mortgage
Securities Corp. (or Sears Mortgage if PNC Mortgage  Securities Corp.  succeeded
to rights and duties of Sears) or mortgage related  securities  containing loans
or mortgages  originated by PNC Bank or its affiliates,  including  Midland Loan
Services,  Inc.  It  is  possible  under  certain  circumstances,  PNC  Mortgage
Securities Corp. or its affiliates,  including Midland Loan Services, Inc. could
have  interests  that are in conflict with the holders of these  mortgage-backed
securities,  and such holders could have rights against PNC Mortgage  Securities
Corp. or its affiliates, including Midland Loan Services, Inc.

     The federal income tax basis of the Trust's investments at October 31, 1999
was $637,646,079 and, accordingly,  net unrealized  depreciation was $16,391,828
(gross  unrealized  appreciation  $22,578,062;   gross  unrealized  depreciation
$38,969,890).

     For federal income tax purposes,  the Trust has a capital loss carryforward
at  October  31,  1999 of  approximately  $102,707,800  of  which  approximately
$3,440,300 will expire in 2001,  approximately  $23,358,000 will expire in 2002,
approximately  $15,428,300 will expire in 2003,  approximately  $27,373,200 will
expire in 2004, and approximately  $33,108,000 will expire in 2007. Accordingly,
no capital gains  distribution is expected to be paid to shareholders  until net
gains have been realized in excess of such amounts.

     Details of open  financial  futures  contracts  at October  31, 1999 are as
follows:

     The Trust entered into four interest rate caps.  Under all  agreements  the
Trust  receives the excess,  if any, of a floating  rate over a fixed rate.  The
Trust paid a transaction fee for each agreement.  Details of the caps at October
31, 1999 are as follows:

NOTE 4. BORROWINGS     REVERSE REPURCHASE AGREEMENTS:   The  Trust  enters  into
                       reverse repurchase agreements with qualified, third party
broker-dealers  as determined by and under the direction of the Trust's Board of
Directors.  Interest on the value of reverse  repurchase  agreements  issued and
outstanding is based upon competitive  market rates at the time of issuance.  At
the time the Trust enters into a reverse  repurchase  agreement,  it establishes
and maintains a segregated  account with the lender containing liquid investment
grade securities  having a value not less than the repurchase  price,  including
accrued interest, of the reverse repurchase agreement.

     The average  daily  balance of reverse  repurchase  agreements  outstanding
during the year ended  October  31,  1999 was  approximately  $204,436,000  at a
weighted  average  interest rate of  approximately  4.77%. The maximum amount of
reverse repurchase agreements outstanding at any month-end during the period was
$238,025,000 as of February 28, 1999, which was 29.88% of total assets.

DOLLAR  ROLLS:  The Trust  enters  into  dollar  rolls in which the Trust  sells
securities  for delivery in the current  month and  simultaneously  contracts to
repurchase  substantially similar (same type, coupon and maturity) securities on
a specified future date.  During the roll period the Trust forgoes principal and
interest paid on the securities. The Trust is compensated by the interest earned
on the cash  proceeds of the initial sale and by the lower  repurchase  price at
the future date.

     The average  monthly  balance of dollar rolls  outstanding  during the year
ended  October 31, 1999 was  approximately  $13,166,793.  The maximum  amount of
dollar rolls  outstanding at any month-end during the year was $60,312,500 as of
January 31, 1999, which was 8.07% of total assets.


NOTE 5. CAPITAL      There are 200 million shares of $.01 par value common stock
                     authorized. Of the 62,849,878 shares outstanding at October
31, 1999, the Adviser owned 10,753 shares.

NOTE 6. DIVIDENDS    Subsequent  to October 31, 1999,  the Board of Directors of
                     the Trust declared dividends from undistributed earnings of
$0.046875  per share  payable  November  30, 1999 to  shareholders  of record on
November 15, 1999.

                         REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------

The Shareholders and Board of Directors of
The BlackRock Income Trust Inc.:

     We have  audited  the  accompanying  statement  of assets and  liabilities,
including the portfolio of investments,  of The BlackRock Income Trust Inc. (the
"Trust") as of October 31, 1999 and the related  statements of operations and of
cash flows for the year then ended,  the  statement of changes in net assets for
the two years then ended,  and financial  highlights  for each of the five years
then  ended.  These  financial  statements  and  financial  highlights  are  the
responsibility of the Trust's  management.  Our  responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our procedures included confirmation of securities owned at October
31, 1999,  by  correspondence  with the  custodian  and  brokers.  An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

     In our opinion,  such financial statements and financial highlights present
fairly, in all material respects, the financial position of The BlackRock Income
Trust Inc.  at October  31,  1999 and the  results of its  operations,  its cash
flows,  the  changes  in its net  assets and the  financial  highlights  for the
respective  stated  periods in conformity  with  generally  accepted  accounting
principles.

                                 TAX INFORMATION
- --------------------------------------------------------------------------------

     We wish to  advise  you as to the  federal  tax  status  of  dividends  and
distributions paid by the Trust during its fiscal year ended October 31, 1999.

     During the fiscal year ended October 31, 1999, the Trust paid dividends and
distributions of $0.56 per share from net investment  income. For federal income
tax  purposes,  the  aggregate of any  dividends  and  short-term  capital gains
distributions you received are reportable in your 1999 federal income tax return
as ordinary income. Further, we wish to advise you that your income dividends do
not qualify for the dividends received deduction.

     For the purpose of preparing  your 1999 annual  federal  income tax return,
however, you should report the amounts as reflected on the appropriate Form 1099
DIV which will be mailed to you in January 2000.

- --------------------------------------------------------------------------------
                           DIVIDEND REINVESTMENT PLAN
- --------------------------------------------------------------------------------

     Pursuant  to  the  Trust's   Dividend   Reinvestment   Plan  (the  "Plan"),
shareholders may elect to have all  distributions of dividends and capital gains
reinvested  by State Street Bank and Trust  Company (the "Plan  Agent") in Trust
shares  pursuant to the Plan.  Shareholders  who do not  participate in the Plan
will receive all  distributions  in cash paid by check in United States  dollars
mailed  directly  to the  shareholders  of record  (or if the shares are held in
street or other nominee  name,  then to the nominee) by the transfer  agent,  as
dividend disbursing agent.

     The Plan Agent serves as agent for the  shareholders in  administering  the
Plan.  After the Trust  declares a dividend or determines to make a capital gain
distribution,  the  transfer  Agent will  acquire  shares for the  participants'
accounts,  depending upon the circumstances  described below, either (i) through
receipt of unissued but authorized shares from the Trust ("newly issued shares")
or (ii) by purchase of  outstanding  shares on the open market,  on the New York
Stock  Exchange or  elsewhere  ("open-market  purchases").  If, on the  dividend
payment date,  the net asset value per share is equal to or less than the market
price per share plus  estimated  brokerage  commissions  (such  condition  being
referred  to herein as "market  premium"),  the  transfer  agent will invest the
dividend amount in newly issued shares on behalf of the participants. The number
of newly  issued  shares to be credited to each  participant's  account  will be
determined  by dividing the dollar amount of the dividend by the net asset value
per share (but in no event less than 95% of the then  current  market  price per
share) on the date the shares are issued.  If, on the dividend payment date, the
net asset  value per share is  greater  than the  market  value per share  (such
condition  being  referred to herein as "market  discount"),  the transfer agent
will invest the dividend amount in shares acquired on behalf of the participants
in open-market purchases.

     Participants  in the Plan may withdraw from the Plan upon written notice to
the Plan Agent and will receive  certificates  for whole Trust shares and a cash
payment will be made for any fraction of a Trust share.

     The Plan Agent's fees for the handling of the reinvestment of dividends and
distributions  will be paid by the Trust.  However,  each participant will pay a
pro rata  share of  brokerage  commissions  incurred  with  respect  to the Plan
Agent's open market  purchases in connection with the  reinvestment of dividends
and  distributions.  The automatic  reinvestment of dividends and  distributions
will not relieve  participants of any federal,  state or local income taxes that
may be payable on such dividends or distributions.

     The Trust  reserves the right to amend or terminate  the Plan as applied to
any dividend or  distribution  paid  subsequent to written  notice of the change
sent to all  shareholders  of the Trust at least 90 days  before the record date
for the dividend or distribution.  The Plan also may be amended or terminated by
the Plan Agent upon at least 90 days' written notice to all  shareholders of the
Trust.  All  correspondence  concerning  the Plan should be directed to the Plan
Agent at (800) 699-1BFM. The addresses are on the front of this report.

                         THE BLACKROCK INCOME TRUST INC.
                             ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------

     There have been no material changes in the Trust's investment objectives or
policies  that have not been approved by the  shareholders  or to its charter or
by-laws or in the  principal  risk factors  associated  with  investment  in the
Trust.  There have been no changes in the persons who are primarily  responsible
for the day-to-day management of the Trust's portfolio.

     YEAR 2000  READINESS  DISCLOSURE.  The Trust has evaluated its  information
technology  infrastructure  for Year 2000 compliance.  Substantially  all of the
Trust's information systems are supplied by the Adviser. The Adviser has advised
the Trust that it has evaluated whether such systems are year 2000 compliant and
that it expects to incur costs of up to  approximately  one  million  dollars to
complete such evaluation and to make any  modifications to its systems as may be
necessary to achieve Year 2000 compliance. The Adviser advised the Trust that it
has fully tested its systems for Year 2000 compliance. The Trust may be required
to bear a portion  of such cost  incurred  by the  Adviser in this  regard.  The
Adviser advised the Trust that it does not anticipate any material disruption in
the operations of the Trust as a result of any failure by the Adviser to achieve
Year 2000  compliance.  There can be no assurance that the costs will not exceed
the amount  referred to above or that the Trust will not experience a disruption
in operations.

     The Adviser has advised  the Trust that it is  continuing  to evaluate  the
Year 2000  compliance  of various  suppliers  of the Adviser and the Trust.  The
Adviser  advised  the Trust  that it has  communicated  with such  suppliers  to
determine their Year 2000 compliance  status and the extent to which the Adviser
or the Trust could be affected by any supplier's Year 2000 compliance issues. To
date the Adviser received  responses from  substantially all such suppliers with
respect to their Year 2000 compliance.  However,  there can be no assurance that
the systems of such suppliers,  who are beyond the Trust's control, will be Year
2000 compliant.  In the event that any of the Trust's  significant  suppliers do
not successfully  and timely achieve Year 2000 compliance,  the Trust's business
or operations could be adversely affected. The Adviser advised the Trust that it
has prepared a contingency plan for Year 2000 compliance by its suppliers. There
can be no assurance that such  contingency plan will be successful in preventing
a disruption of the Trust's operations.

                         THE BLACKROCK INCOME TRUST INC.
                               INVESTMENT SUMMARY
- --------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVE

The BlackRock  Income Trust's  investment  objective is to manage a portfolio of
high  quality  securities  to  miantain  high  monthly  income  consistent  with
preservation of capital.  The Trust will seek to distribute  monthly income that
is greater than that  obtainable on an annualized  basis by investment in United
States  Treasury  securities  having the same  maturity  as the  average  dollar
weighted maturity of the Trust's investments.

WHO MANAGES THE TRUST?

BlackRock  Financial  Management,   Inc.   ("BlackRock")  is  an  SEC-registered
investment  adviser.  As of September  30, 1999,  BlackRock  and its  affiliates
managed over $148 billion on behalf of taxable and tax-exempt clients worldwide.
Strategies  include  fixed  income,  equity  and cash and may  incorporate  both
domestic and international securities.  Domestic fixed income strategies utilize
the  government,  mortgage,  corporate  and municipal  bond  sectors.  BlackRock
manages twenty-three  closed-end funds that are traded on either the New York or
American stock  exchanges,  and a $24 billion family of open-end equity and bond
funds.  BlackRock manages over 487 accounts,  domiciled in the United States and
overseas.

WHAT CAN THE TRUST INVEST IN?

The Trust will invest at least 65% of its assets in mortgage-backed  securities.
At least 85% of the  Trust's  assets  must be rated at least "AAA" by Standard &
Poor's or "Aaa" by Moody's at the time of purchase.  Of this 85% at least 80% of
the Trust's assets must be rated at least "AAA" by Standard & Poor's at the time
of purchase while the remaining 5% can be invested in securities  rated at least
"AAA" by Standard & Poor's,  "Aaa" by Moody's or deemed  "AAA" by the Advisor at
the time of purchase. Additionally, 15% of the Trust's assets can be invested in
securities  rated at least "AA" by  Standard & Poor's or "Aa" by Moody's at time
of purchase. Under current market conditions, BlackRock expects that the primary
investments of the Trust will be U.S. government  securities,  securities backed
by government  agencies (such as mortgage-backed  securities),  privately issued
mortgage-backed   securities,    commercial   mortgage-backed   securities   and
asset-backed securities.

WHAT IS THE ADVISER'S INVESTMENT STRATEGY?

The Adviser will seek to meet the Trust's  investment  objective by managing the
assets of the Trust so as to provide high  monthly  income  consistent  with the
preservation  of capital.  The Trust will seek to provide monthly income that is
greater  than that  which  could be  obtained  by  investing  in U .S.  Treasury
securities  with an average  life similar to that of the Trust's  assets.  Under
current market conditions, the average life of the Trust's assets is expected to
be in the  range of seven to ten  years.  Under  other  market  conditions,  the
Trust's average life may vary and may not be predictable  using any formula.  In
seeking the investment objective,  the Adviser may actively manage among various
types  of  securities  in  different  interest  rate  environments.  Traditional
mortgage  pass-through  securities  make  interest and  principal  payments on a
monthly basis and can be a source of  attractive  levels of income to the Trust.
While  mortgage-backed  securities in the Trust are of high credit quality, they
typically  offer a yield spread above  Treasuries due to the  uncertainty of the
timing  of their  cash  flows  as they are  subject  to  changes  in the rate of
prepayments when interest rates change and either a larger or smaller proportion
of mortgage  holders  refinance their mortgages or move.  While  mortgage-backed
securities offer the opportunity for attractive yields, they subject a portfolio
to interest rate risk and prepayment  exposure which result in reinvestment risk
when prepaid principal must be reinvested.  Multiple-class mortgage pass-through
securities,   or  collateralized   mortgage  obligations  (CMOs),  are  also  an
investment  that may be used in the  Trust's  portfolio.  These  securities  are
issued in multiple  classes each of which has a different  coupon  rate,  stated
maturity and  prioritization  on the timing of receipt of cash flows coming from
interest  and  principal  payments  on  the  underlying   mortgages.   Principal
prepayments can be allocated among the different classes of a CMO in a number of
ways;  for instance,  they can be applied to each of the classes in the order of
their respective  stated  maturities.  This feature allows an investor to better
plan the average life of their investment. Additionally, in order to protect the
portfolio from interest rate risk, the Adviser will attempt to locate securities
with  call  protection,  such  as  commercial  mortgage-backed  securities  with
prepayment penalties or lockouts. Securities with call protection should provide
the portfolio with some degree of protection  against  reinvestment  risk during
times of lower prevailing interest rates.

HOW ARE THE TRUST'S  SHARES  PURCHASED  AND SOLD?  DOES THE TRUST PAY  DIVIDENDS
REGULARLY?

The Trust's  shares are traded on the New York  Stock  Exchange  which  provides
investors with  liquidity on a daily basis.  Orders to buy or sell shares of the
Trust must be placed through a registered broker or financial adviser. The Trust
pays monthly  dividends which are typically paid on the last business day of the
month. For shares held in the shareholder's name, dividends may be reinvested in
additional shares of the Trust through the Trust's transfer agent,  State Street
Bank & Trust Company.  Investors who wish to hold shares in a brokerage  account
should check with their financial  adviser to determine  whether their brokerage
firm offers dividend reinvestment services.

LEVERAGE CONSIDERATIONS IN THETRUST

Under current  market  conditions,  leverage  increases the income earned by the
Trust.  The  Trust  employs  leverage  primarily  through  the  use  of  reverse
repurchase  agreements  and dollar rolls.  Leverage  permits the Trust to borrow
money at short-term  rates and reinvest that money in  longer-term  assets which
typically offer higher interest  rates.  The difference  between the cost of the
borrowed  funds and the  income  earned on the  proceeds  that are  invested  in
longer-term  assets is the benefit to the Trust from leverage.  In general,  the
portfolio  is  typically  leveraged  at  approximately  331/3% of total  assets.
Leverage also increases the duration (or price  volatility of the net assets) of
the Trust,  which can improve the  performance  of the Trust in a declining rate
environment,  but can cause net  assets to decline  faster  than the market in a
rapidly rising rate environment.  BlackRock's  portfolio  managers  continuously
monitor and  regularly  review the  Trust's  use of  leverage  and the Trust may
reduce,  or unwind,  the amount of leverage  employed should BlackRock  consider
that reduction to be in the best interests of the shareholders.

SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO THE TRUST

THE TRUST IS  INTENDED  TO BE A  LONG-TERM  INVESTMENT  AND IS NOT A  SHORT-TERM
TRADING VEHICLE.

INVESTMENT  OBJECTIVE.  Although  the  objective of the Trust is to provide high
montly income consistent with preservation of capital, there can be no assurance
that this objective will be achieved.

DIVIDEND  CONSIDERATIONS.  Dividends  paid by the Trust are  likely to vary over
time as fixed income market conditions change. Future dividends may be higher or
lower than the dividend the Trust is currently paying.

INTEREST-ONLY SECURITIES (IO). The yield to maturity on an IO class is extremely
sensitive  to the rate of  principal  payments  (including  prepayments)  on the
related  underlying  Mortgage Assets, and a rapid rate of principal payments may
have a material  adverse  effect on such  security's  yield to maturity.  If the
underlying  Mortgage Assets experience  greater than anticipated  prepayments of
principal,  the Trust may fail to recoup fully its initial  investment  in these
securities  even  if the  securities  are  rated  AAA by S&P or Aaa by  Moody's.

LEVERAGE.  The Trust utilizes leverage through reverse repurchase agreements and
dollar rolls,  which  involves  special  risks.  The Trust's net asset value and
market value may be more  volatile  due to its use of leverage.

MARKET PRICE OF SHARES.  The shares of closed-end  investment  companies such as
the Trust trade on the New York Stock  Exchange  (NYSE symbol:  BKT) and as such
are subject to supply and demand influences.  As a result, shares may trade at a
discount or a premium to their net asset value.

MORTGAGE-BACKED   AND   ASSET-BACKED   SECURITIES.   The  cash  flow  and  yield
characteristics of these securities differ from traditional debt securities. The
major  differences  typically include more frequent payments and the possibility
of  prepayments  which  will  change  the  yield to  maturity  of the  security.

CORPORATE  DEBT  SECURITIES.  The value of corporate debt  securities  generally
varies inversely with changes in prevailing market interest rates. The Trust may
be subject to certain  reinvestment  risks in environments of declining interest
rates.

ZERO COUPON SECURITIES. Such securities receive no cash flows prior to maturity;
therefore, interim price movement on the securities are generally more sensitive
to interest rate movements then securities  that make periodic coupon  payments.

ILLIQUID  SECURITIES.  The Trust may  invest in  securities  that are  illiquid,
although  under current  market  conditions the Trust expects to do so to only a
limited extent. These securities involve special risks.

ANTITAKEOVER  PROVISIONS.  Certain antitakeover provisions will make a change in
the Trust's  business or management  more difficult  without the approval of the
Trust's Board of Directors and may have the effect of depriving  shareholders of
an  opportunity  to sell their shares at a premium above the  prevailing  market
price.

                                    underlying   pool  of   mortgage   loans  or

                                    known as a strip.

INVERSE-FLOATING RATE MORTGAGE:     Mortgage   instruments   with  coupons  that
                                    adjust at periodic intervals  according to a

                                    level interest rate index.

MARKET PRICE:                       Price per share of a security trading in the
                                    secondary  market.  For a  closed-end  fund,
                                    this is the  price at which one share of the
                                    fund  trades on the stock  exchange.  If you
                                    were to buy or sell shares, you would pay or
                                    receive the market price.

MORTGAGE DOLLAR ROLLS:              A mortgage  dollar roll is a transaction  in
                                    which   the  Trust   sells   mortgage-backed
                                    securities for delivery in the current month
                                    and  simultaneously  contracts to repurchase
                                    substantially   similar  (although  not  the
                                    same) securities on a specified future date.
                                    During the "roll" period, the Trust does not
                                    receive  principal and interest  payments on
                                    the  securities,   but  is  compensated  for
                                    giving up these  payments by the  difference
                                    in the  current  sales  price (for which the
                                    security  is sold) and lower  price that the
                                    Trust pays for the  similar  security at the
                                    end date as well as the  interest  earned on
                                    the cash proceeds of the initial sale.

MORTGAGE PASS-THROUGHS:             Mortgage-backed  securities  issued by FNMA,
                                    FHLMC, FHA or GNMA.

NET  ASSET VALUE (NAV):             Net asset value is the total market value of
                                    all  securities and other assets held by the
                                    Trust,    plus   income   accrued   on   its
                                    investments, minus any liabilities including
                                    accrued  expenses,   divided  by  the  total
                                    number  of  outstanding  shares.  It is  the
                                    underlying  value  of a  single  share  on a
                                    given day.  Net asset value for the Trust is
                                    calculated  weekly and published in BARRON'S
                                    on Saturday  and THE WALL STREET  JOURNAL on
                                    Monday.

PRINCIPAL-ONLY SECURITIES:          Mortgage  securities  that  receive only the
                                    principal cash flows from an underlying pool
                                    of mortgage loans or underlying pass-through
                                    securities. Also known as a strip.

PROJECT LOANS:                      Mortgages   for   multi   family,   low-  to
                                    middle-income housing.

PREMIUM:                            When a fund's  stock  price is greater  than
                                    its net asset value,  the fund is said to be
                                    trading at a premium.

REMIC:                              A real estate mortgage investment conduit is
                                    a   multiple-class    security   backed   by
                                    mortgage-backed securities or whole mortgage
                                    loans and  formed  as a trust,  corporation,
                                    partnership,  or  segregated  pool of assets
                                    that  elects  to be  treated  as a REMIC for
                                    federal tax purposes. Generally, FNMA REMICs
                                    are  formed  as  trusts  and are  backed  by
                                    mortgage-backed securities.

RESIDUALS:                          Securities   issued   in   connection   with
                                    collateralized   mortgage  obligations  that
                                    generally  represent  the  excess  cash flow
                                    from the mortgage assets  underlying the CMO
                                    after  payment of principal  and interest on
                                    the  other  CMO   securities   and   related
                                    administrative expenses.

REVERSE REPURCHASE
AGREEMENT:                          In a reverse repurchase agreement, the Trust
                                    sells  securities  and agrees to  repurchase
                                    them at a  mutually  agreed  date and price.
                                    During  this time,  the Trust  continues  to
                                    receive the principal and interest  payments
                                    from that security.  At the end of the term,
                                    the Trust receives the same  securities that
                                    were sold for the same initial dollar amount
                                    plus  interest  on the cash  proceeds of the
                                    initial sale.

STRIPPED MORTGAGE-BACKED
SECURITIES:                         Arrangements  in which a pool of  assets  is
                                    separated  into  two  classes  that  receive
                                    different  proportions  of the  interest and
                                    principal   distributions   from  underlying
                                    mortgage-backed  securities.  IO's  and PO's
                                    are examples of strips.

                      BLACKROCK FINANCIAL MANAGEMENT, INC.
                                   AN OVERVIEW
- --------------------------------------------------------------------------------

     BlackRock  Financial  Management,  Inc.  ("BlackRock") is an SEC-registered
investment  adviser.  As of Septemebr  30, 1999,  BlackRock  and its  affiliates
managed over $148 billion on behalf of taxable and tax-exempt clients worldwide.
Strategies  include  fixed  income,  equity  and cash and may  incorporate  both
domestic and international securities. BlackRock manages twenty-three closed-end
funds that are traded on either the New York or American stock exchanges,  and a
$24 billion  family of open-end  funds.  BlackRock  manages  over 487  accounts,
domiciled in the United States and overseas.

     BlackRock's fixed income product was introduced in 1988 by a team of highly
seasoned  fixed  income   professionals.   These   professionals  had  extensive
experience   creating,   analyzing   and  trading  a  variety  of  fixed  income
instruments,  including the most complex structured securities. In fact, several
individuals  at BlackRock  were  responsible  for  developing  many of the major
innovations  in  the  mortgage-backed   and  asset-backed   securities  markets,
including   the  creation  of  the  first  CMO,  the  floating   rate  CMO,  the
senior/subordinated pass-through and the multi-class asset-backed security.

     BlackRock  is unique  among  asset  management  and  advisory  firms in the
emphasis it places on the  development of proprietary  analytical  capabilities.
Over one  quarter  of the  firm's  professionals  is  dedicated  to the  design,
maintenance  and use of these  systems,  which are not  otherwise  available  to
investors. BlackRock's proprietary analytical tools are used for evaluating, and
designing fixed income investment  strategies for client portfolios.  Securities
purchased include mortgages,  corporate bonds,  municipal bonds and a variety of
hedging instruments.

     BlackRock  has  developed  investment  products  that respond to investors'
needs and has been  responsible  for several  major  innovations  in  closed-end
funds. In fact,  BlackRock  introduced the first  closed-end  mortgage fund, the
first taxable and tax-exempt  closed-end funds to offer a finite term, the first
closed-end  fund to  achieve a AAA rating by  Standard  & Poor's,  and the first
closed-end  fund to invest  primarily in North American  Government  securities.
Currently,  BlackRock's closed-end funds have dividend reinvestment plans, which
are designed to provide  ongoing  demand for the stock in the secondary  market.
BlackRock  manages a wide range of  investment  vehicles,  each having  specific
investment objectives and policies.

     In view of our  continued  desire to provide a high level of service to all
our shareholders, BlackRock maintains a toll-free number for your questions. The
number is (800) 227-7BFM (7236).  We encourage you to call us with any questions
that you may have about your BlackRock  funds and we thank you for the continued
trust that you place in our abilities.
