COLONIAL HIGH YIELD MUNICIPAL FUND HIGHLIGHTS
DECEMBER 1, 1997 - MAY 31, 1998
INVESTMENT OBJECTIVE: Colonial High Yield Municipal Fund seeks a high level of
after-tax total return by pursuing current income exempt from ordinary federal
income tax and opportunities for long-term appreciation from a portfolio
primarily invested in medium-to lower-grade municipal bonds.
PORTFOLIO MANAGER COMMENTARY: "We entered this period with the portfolio
structured to benefit from declining interest rates. Though
stronger-than-expected economic growth in the first quarter of 1998 resulted in
some interest rate volatility, rates did decline modestly from the beginning of
the period to the end. In this environment, your Fund provided solid returns."

Quality weightings are calculated as a percentage of total investments,
including short-term obligations. Because the Fund is actively managed, there
can be no guarantee the Fund will continue to maintain these quality weightings
in the future.
(1) A portion of the Fund's income may be subject to the alternative
minimum tax.
(2) The 30-day SEC yields on May 31, 1998 reflect the portfolio's earning power,
net of expenses, expressed as an annualized percentage of the public offering
price per share at the end of the period. If the Distributor had not waived
certain Fund expenses, the SEC yield for Class C shares would have been 4.11%.
(3) Taxable-equivalent SEC yields are based on the maximum federal income tax
rate of 39.6%.
The Fund may at times purchase tax-exempt securities at a
discount, and some or all of this discount may be included in the Fund's
ordinary income which will be taxable when distributed.
(4) Performance results reflect any voluntary waivers or reimbursement of Fund
expenses by the Adviser or Distributor. Absent these waivers or reimbursement
arrangements, performance results would have been lower.

PRESIDENT'S MESSAGE
TO FUND SHAREHOLDERS
(PHOTO OF STEPHEN E. GIBSON)
In June 1998, Harold Cogger retired as president of Colonial High Yield
Municipal Fund's Board of Trustees. I would like to take this opportunity to
thank him for his guidance over the past few years and to wish him well. As the
new president of the Fund, I am pleased to present the semiannual report for
Colonial High Yield Municipal Fund for the six-month period ended May 31, 1998.
A variety of factors caused bond prices to seesaw during the period, as
different sectors of the economy provided mixed signals to fixed-income
investors. The economic turmoil in Southeast Asia, with its potential to slow
U.S. economic growth, and the possibility of interest rate increases by the
Federal Reserve Board were strong contributors to price volatility. By the end
of the period, fixed-income investors saw something they liked. With hints that
growth might slow, investors' fear of inflation was reduced. As interest rates
dropped, bond prices finished on a positive note.
The tax-exempt market in which the Fund invests followed a similar pattern. In
addition to the trends mentioned above, supply and demand factors contributed
toward rising and declining prices during the period. While the environment was
a challenging one for municipal bond fund managers, the Fund posted favorable
returns relative to its peers over the six-month period. The following portfolio
management report expands on these issues, provides details on the Fund's
strategies and performance, and offers some insight for the investment period
ahead.
For investors seeking competitive levels of tax-free income and the
potential for long-term price appreciation, Colonial High Yield Municipal Fund
remains a sensible option for their investment portfolio.
Thank you for choosing Colonial High Yield Municipal Fund and for giving us the
opportunity to serve your investment needs.
Respectfully,
/S/ Stephen E. Gibson

PORTFOLIO MANAGEMENT REPORT
MAUREEN NEWMAN is portfolio manager of Colonial High Yield Municipal Fund and is
vice president of Colonial Management Associates, Inc. The following is a
discussion of the Fund's performance for the six-month period ended May 31,
1998.
ECONOMIC AND MARKET FACTORS VARIED DURING THE PERIOD
Conditions for fixed-income investments varied during the period as investors
weighed the fundamental strength of the U.S. economy against the potential for
an economic slowdown caused by the crisis in Southeast Asia. Market sentiment
regarding the likelihood of an interest rate increase by the Federal Reserve
changed several times during the period. Uncertainty about the ability of the
U.S. economy to continue to grow, without igniting inflation, caused bond prices
to alternately rise and decline for much of period. However, by the end of the
period, bond prices finished above the levels of early December.
The tax-exempt bond market experienced price volatility similar to that of the
Treasury bond market. Lower interest rates helped increase the supply of
municipal bonds, as issuers refunded higher coupon debt and financed new
projects as well. The high level of supply caused municipal bonds to
underperform Treasury bonds in the early months of 1998. As the yields on
municipal bonds became increasingly attractive relative to Treasury bonds,
ensuing demand helped push prices higher toward the end of the period.
For the six-month period, the Fund generated a total return of 4.44% for Class A
shares, based on net asset value. This compares favorably with the performance
of the Fund's Lipper peer group average with a total return of 3.99% for the
same period.(1)
FUND WAS POSITIONED TO BENEFIT FROM DECLINING INTEREST RATES
Based on our long-term outlook for low inflation and modest economic growth, we
structured the Fund to take advantage of a potential decline in interest rates.
As interest rates fell, two factors in particular contributed positively toward
the Fund's performance during the period: refunding and our duration management
strategy.
The refunding of some of our non-rated and lower-quality callable bonds helped
boost the Fund's value during the period. As rates fall, issuers seeking to take
advantage of lower rates may "refund" their bonds. In doing so, new bonds are
issued and their proceeds are used to buy Treasury bonds with cash flows
targeted to pay the debt service on the refunded bonds. Since Treasury bonds now
back the original bonds, the credit rating of those bonds can be upgraded to
AAA. This generally increases the value of the bonds.
Duration management is a tool designed to help predict and control the degree to
which a fund's share price will fluctuate in response to a change in interest
rates. It takes into account a variety of factors, including the maturity of the
4
<PAGE>
bonds held in the portfolio. In general, the longer a fund's duration, the more
movement you would expect in its share price. By maintaining a duration that was
slightly longer than that of the competition, your Fund's share price
appreciated when interest rates fell during the period.
OUTLOOK FOR A POSITIVE ECONOMIC AND MARKET ENVIRONMENT
Our long-term outlook remains positive. We expect that low inflation and modest
economic growth will continue. Sustained high levels of productivity and global
competition are likely to keep inflation pressure low. The economic slowdown in
Asia should help keep the U.S. economy from growing too fast. The current
federal budget surplus may limit the government's need to borrow money, and
thus, the need to issue U.S. government securities. This could help create
higher demand for alternative fixed-income investments, including municipal
bonds.
We will continue to de-emphasize investments in highly cyclical industries like
steel and airlines, which tend to underperform when growth rates decline. On the
other hand, we intend to increase our holdings related to basic services such as
schools and hospitals. These sectors tend to maintain their value better in an
economic downturn. Considering these factors, the Fund will remain positioned
for a declining interest rate environment. However, we do anticipate some
variability in interest rates in the months to come. Therefore, we will continue
to actively manage all aspects of the Fund to decrease the potential negative
effects of rate volatility.

Returns and value of an investment will vary, resulting in a gain or loss on
sale. All results shown assume reinvestment of distributions. Net asset value
(NAV) returns do not include sales charges or contingent deferred sales charges
(CDSC). Public offering price (POP) returns include the maximum sales charges of
4.75%. The CDSC returns reflect the maximum charges of 5% for one year, 2% for
five years and 1% since inception for Class B and 1% for one year for Class C
shares. Past performance cannot predict future results.
Performance results reflect any voluntary waivers or reimbursement of Fund
expenses by the Adviser or Distributor. Absent these waivers or reimbursement
arrangements, performance results would have been lower.
Performance for different share classes will vary based on differences in sales
charges and fees associated with each class.
Class A and Class C shares (newer class shares) performance information includes
returns of the Fund's Class B shares (the oldest existing fund class) for
periods prior to the inception dates of the newer class shares. These Class B
share returns are not restated to reflect any expense differential (e.g., Rule
12b-1 fees) between Class B and the newer class shares.
The Lehman Brothers Municipal Bond Index is a broad-based, unmanaged index that
tracks the performance of the municipal bond market. Unlike mutual funds,
indexes are not investments, do not incur fees or expenses and it is not
possible to invest in an index.

NOTES TO FINANCIAL STATEMENTS
MAY 31, 1998 (UNAUDITED)
NOTE 1. INTERIM FINANCIAL STATEMENTS
In the opinion of management of Colonial High Yield Municipal Fund (the
Fund), a series of Colonial Trust IV, the accompanying financial
statements contain all normal and recurring adjustments necessary for
the fair presentation of the financial position of the Fund at May 31,
1998, and the results of its operations, the changes in its net assets
and the financial highlights for the six months then ended.
NOTE 2. ACCOUNTING POLICIES
ORGANIZATION: The Fund is a diversified portfolio of a Massachusetts
business trust, registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company. The Fund's
investment objective is to seek as high a level of after-tax total
return by pursuing current income exempt from ordinary federal income
tax and opportunities for long-term appreciation from a portfolio
primarily invested in medium-to-lower-grade municipal bonds. The Fund
may issue an unlimited number of shares. The Fund offers three classes
of shares: Class A, Class B, and Class C. Class A shares are sold with a
front-end sales charge and Class B shares are subject to an annual
distribution fee and a contingent deferred sales charge. Class B shares
will convert to Class A shares when they have been outstanding
approximately eight years. Class C shares are subject to a contingent
deferred sales charge on redemptions made within one year after purchase
and an annual distribution fee.
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. The following is a summary of significant accounting policies
that are consistently followed by the Fund in the preparation of its
financial statements.
SECURITY VALUATION AND TRANSACTIONS: Debt securities generally are
valued by a pricing service based upon market transactions for normal,
institutional-size trading units of similar securities. When management
deems it appropriate, an over-the-counter or exchange bid quotation is
used.
Futures contracts are valued based on the difference between the last
sale price and the opening price of the contract.
Short-term obligations with a maturity of 60 days or less are valued at
amortized cost.
Portfolio positions for which market quotations are not readily
available are valued at fair value under procedures approved by the
Trustees.
27
<PAGE>
Notes to Financial Statements/May 31, 1998
NOTE 2. ACCOUNTING POLICIES - CONT.
Security transactions are accounted for on the date the securities are
purchased, sold or mature.
Cost is determined and gains and losses are based upon the specific
identification method for both financial statement and federal income
tax purposes.
The Fund may trade securities on other than normal settlement terms.
This may increase the risk if the other party to the transaction fails
to deliver and causes the Fund to subsequently invest at less
advantageous prices.
DETERMINATION OF CLASS NET ASSET VALUES AND FINANCIAL HIGHLIGHTS: All
income, expenses (other than the Class B and Class C distribution fees),
and realized and unrealized gains (losses), are allocated to each class
proportionately on a daily basis for purposes of determining the net
asset value of each class.
Class B and Class C per share data and ratios are calculated by
adjusting the expense and net investment income per share data and
ratios for the Fund for the entire period by the distribution fee
applicable to Class B and Class C shares only.
FEDERAL INCOME TAXES: Consistent with the Fund's policy to qualify as a
regulated investment company and to distribute all of its taxable
income, no federal income tax has been accrued.
INTEREST INCOME, DEBT DISCOUNT AND PREMIUM: Interest income is recorded
on the accrual basis. Original issue discount is accreted to interest
income over the life of a security with a corresponding increase in the
cost basis; market discount is not accreted. Premium is amortized
against interest income with a corresponding decrease in the cost basis.
DISTRIBUTIONS TO SHAREHOLDERS: The Fund declares and records
distributions daily and pays monthly.
The amount and character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ
from generally accepted accounting principles. Reclassifications are
made to the Fund's capital accounts to reflect income and gains
available for distribution (or available capital loss carryforwards)
under income tax regulations.
NOTE 3. FEES AND COMPENSATION PAID TO AFFILIATES
MANAGEMENT FEE: Colonial Management Associates, Inc. (the Adviser) is
the investment Adviser of the Fund and furnishes accounting and other
services and office facilities for a monthly fee based on each fund's
pro-rata portion of the combined average net assets of the Fund,
Colonial
28
<PAGE>
Notes to Financial Statements/May 31, 1998
Tax-Exempt Fund and Colonial Tax-Exempt Insured Fund as follows:
Average Net Assets Annual Fee Rate
------------------ ---------------
First $1 billion 0.60%
Next $2 billion 0.55%
Next $1 billion 0.50%
Over $4 billion 0.45%
BOOKKEEPING FEE: The Adviser provides bookkeeping and pricing services
for $27,000 per year plus 0.035% of the Fund's average net assets over
$50 million.
TRANSFER AGENT FEE: Colonial Investors Service Center, Inc. (the
Transfer Agent), an affiliate of the Adviser, provides shareholder
services for a monthly fee equal to 0.13% annually of the Fund's average
net assets and receives reimbursement for certain out-of-pocket
expenses.
Effective January 1, 1997 and continuing through calendar year 1997, the
Transfer Agent fee was reduced by 0.01% in cumulative monthly
increments, resulting in a decrease in the fee from 0.14% to 0.13%
annually.
UNDERWRITING DISCOUNTS, SERVICE AND DISTRIBUTION FEES: Liberty Funds
Distributor, Inc., formerly Liberty Financial Investments, Inc. (the
Distributor), a subsidiary of the Adviser, is the Fund's principal
underwriter. For the six months ended May 31, 1998, the Fund has been
advised that the Distributor retained net underwriting discounts of
$14,762 on sales of the Fund's Class A shares and received contingent
deferred sales charges (CDSC) of $244,623 and $397 on Class B and Class
C share redemptions respectively.
The Fund has adopted a 12b-1 plan which requires the payment of a
service fee to the Distributor equal to 0.25% annually of the Fund's net
assets as of 20th of each month. The plan also requires the payment of a
distribution fee to the Distributor equal to 0.75%, annually, of the
average net assets attributable to Class B and Class C shares. The
Distributor has voluntarily agreed, until further notice, to waive a
portion of the Class C share distribution fee so that it does not exceed
0.60% annually.
The CDSC and the fees received from the 12b-1 plan are used principally
as repayment to the Distributor for amounts paid by the Distributor to
dealers who sold such shares.
OTHER: The Fund pays no compensation to its officers, all of whom are
employees of the Adviser.
The Fund's Trustees may participate in a deferred compensation plan
which may be terminated at any time. Obligations of the plan will be
paid solely out of the Fund's assets.

NOTE 4. PORTFOLIO INFORMATION
Investment activity: During the six months ended May 31, 1998, purchases
and sales of investments, other than short-term obligations were
$32,887,231 and $36,619,323, respectively.
Unrealized appreciation (depreciation) at May 31, 1998, based on cost of
investments for federal income tax purposes was:

Gross unrealized appreciation $ 13,598,109

Net unrealized appreciation $ 11,653,317
===============
</TABLE>
CAPITAL LOSS CARRYFORWARDS: At November 30, 1997, capital loss
carryforwards, available (to the extent provided in regulations) to
offset future realized gains were approximately as follows:
<TABLE>
<CAPTION>
Year of Capital loss
expiration carryforward
---------- ------------
<S> <C>
1998 $ 590,000
1999 364,000
2000 302,000
2002 1,731,000
2003 2,383,000
2005 1,526,000
------------
$ 6,896,000
============
</TABLE>
The loss carryforwards expiring in 1998 and 1999 were acquired in the
merger with Colonial VIP High Yield Municipal Bond Fund.
Expired capital loss carryforwards, if any, are recorded as a reduction
of capital paid in.
To the extent loss carryforwards are used to offset any future realized
gains, it is unlikely that such gains would be distributed since they
may be taxable to shareholders as ordinary income.
OTHER: There are certain risks arising from geographic concentration in
any state. Certain revenue or tax related events in a state may impair
the ability of certain issuers of municipal securities to pay principal
and interest on their obligations.
The Fund may focus its investments in certain industries, subjecting it
to greater risk than a fund that is more diversified.
The Fund may invest in municipal and Treasury bond futures contracts and
purchase and write options on futures. The Fund will invest in these
instruments to hedge against the effects of changes in the value of
portfolio securities due to anticipated changes in interest rates and/or
market conditions, for duration management, or when the transactions are
economically appropriate to the reduction of risk inherent in the
management of the Fund and not for trading purposes. The use of futures
contracts and options involves certain risks which include (1) imperfect
correlation between the price movement of the instruments and the
underlying securities,
30
<PAGE>
Notes to Financial Statements/May 31, 1998
(2) inability to close out a position due to different trading hours or
the temporary absence of a liquid market for either the instrument or
the underlying securities or (3) an inaccurate prediction by the Adviser
of the future direction of interest rates. Any of these risks may
involve amounts exceeding the variation margin recognized in the Fund's
Statement of Assets and Liabilities at any given time.
NOTE 5. LINE OF CREDIT
The Fund may borrow up to 10% of its net assets under a line of credit
for temporary or emergency purposes. Any borrowings bear interest at one
of the following options determined at the inception of the loan: (1)
federal funds rate plus 1/2 of 1%, (2) the lending bank's base rate or
(3) IBOR offshore loan rate plus 1/2 of 1%. There were no borrowings
under the line of credit during the six months ended May 31, 1998.
