                         DECEMBER 1, 1996 - MAY 31, 1997

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.

THE FUND IS DESIGNED TO OFFER:
  |X|  Potential for high tax-free income
  |X|  Expert credit analysis
  |X|  Experienced professional management

PORTFOLIO MANAGER COMMENTARY: "Your Fund owns a high percentage of Industrial
Revenue (IDR) Bonds. IDRs are issued by corporations rather than municipalities
and carry a tax exemption for a variety of reasons. For example, they may be
part of a revitalization project bringing jobs to a depressed area. Our ability
to evaluate the credit quality of these securities helps us provide extra value
- -- and income -- to individual investors."

                              TO FUND SHAREHOLDERS

[Photo of Harold W. Cogger]

I'm pleased to present your Fund's semiannual report for the six months ending
May 31, 1997.

During the period, the economy was strong, corporate profits continued to grow,
unemployment was at a 25-year low, and inflation continued. For investors in the
stock market, the environment couldn't get much better.

But people who invest in bonds saw it differently. They saw stronger than
expected economic growth in the first part of 1997, creating fears of renewed
inflation. They saw the Federal Reserve Board raising short-term interest rates
in an attempt to slow down the economy. And they saw long-term interest rates
rise steadily.

Between December 1 and mid-April, yields on the benchmark 30-year U.S. Treasury
bond rose from 6.36% to 7.17%. Interest rates on all other bond categories, such
as high yield municipal bonds, rose as well.

Fortunately, by late April the environment began to improve for bond investors.
Interest rates eased downward, the economy was slowing, inflation was still low
and the Federal Reserve Board decided against boosting short-term rates a second
time in two months.

But when the dust settled, interest rates were still moderately higher on
May 31, 1997 compared to December 1, 1996. That means that the prices of
fixed-income securities in your portfolio declined somewhat.

The best news is that your tax-exempt income remains very strong, particularly
compared to inflation. And that's a main attraction of fixed-income investing.

This report provides you with a closer look at your Fund's performance as well
as the portfolio manager's investment strategy. In addition, the report lists
every security in the portfolio as of May 31, 1997, organized by categories such
as education, healthcare and housing.

Thank you for the opportunity to help you meet your investment goals.

    Sincerely,

/s/ Harold W. Cogger

    Harold W. Cogger
    President
    July 16, 1997

Because market conditions change frequently, there can be no assurance that the
trends described here will continue, come to pass or affect Fund performance.

                           PORTFOLIO MANAGEMENT REPORT

BONNY BOATMAN AND PETER ANDERSEN are portfolio co-managers of Colonial High
Yield Municipal Fund. Ms. Boatman is senior vice president of Colonial
Management Associates, Inc. and Director of the Municipal Bond Department. Mr.
Andersen is vice president of Colonial Management Associates, Inc. 

STRONG ECONOMY BOOSTS HIGH YIELD MUNIS

The issuers of high yield municipal bonds are financially less attractive than
investment grade bond issuers. For example, they may have higher levels of debt.
That's why their bonds offer more income. It's vitally important that these
issuers stay financially healthy. Just like "a rising tide lifts all boats," a
strong economy helps these issuers meet their commitments.

Because credit quality is such an important factor in this portfolio, it tends
to overshadow other factors affecting high yield municipal bonds. That's why
rising interest rates -- so crucial to most types of bonds -- have less of a
negative impact on this portfolio.

SCARCE SUPPLY, BOOMING DEMAND

Another factor contributing to your Fund's performance is scarce supply and
strong demand.

New issues of bonds are scarce. Municipalities are awash in tax revenue from the
booming economy. They don't need to issue bonds as urgently to raise cash.

Meanwhile, demand for high yield municipal bonds is strong as investors try to
do better than the rates offered by AAA-rated bonds. Interest rates may be a
little bit higher than they were six months ago, but they're relatively low
compared to where they've been over the past 20 years. Getting the extra yield
from high yield municipal bonds is important to many investors in this interest
rate environment.

So, the scarce supply of bonds and the strong demand for them pushes prices
upward.

TOTAL RETURN MAY BE MODEST, BUT INCOME IS STRONG

For the period, the total return for Class A Shares, based on net asset value,
was 2.07%. In comparison, the Lehman Brothers Municipal Bond Index, a
broad-based unmanaged index that tracks the performance of the municipal bond
market, posted a return of 1.68% for the same period. So even though total
return was modest, we outperformed, the market benchmark.

As of May 31, 1997, your Fund's 30-day yield was 5.33% on Class A shares. For
those of you in the maximum 39.6% effective federal tax bracket, that's
equivalent to a taxable yield of 8.82%.

FINDING DIAMONDS IN THE ROUGH

Unlike investment grade bonds, non-rated bonds are not well followed by the
investment community. But that's a great opportunity to uncover gems and buy
bonds that we think have the potential for a higher credit rating due to
improved circumstances.

WHERE WE'RE HEADED

Investing in high yield municipal bonds requires a specialized skill. These
securities are often low rated or are not rated at all. That puts a special
responsibility on our analytical staff to search for securities that appear
undervalued and have the potential for capital appreciation. We will continue to
search for these bonds as well as providing you with the highest tax-exempt
income consistent with prudent portfolio management.

A $10,000 investment in Class A shares made on 9/1/94 at net asset value (NAV)
would have been valued at $12,274 on 5/31/97. The same investment based on
maximum offering price (MOP) would have grown to $11,691 on 5/31/97.

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

Return and value of an investment will vary, resulting in a gain or loss on
sale. All results shown assume reinvestment of distributions. NAV returns do not
include sales charges or CDSC. MOP returns include the maximum sales charge of
4.75%. The CDSC returns reflect the maximum charge of 5% for one year, 2% for
five years and 1% since inception. 

Past performance cannot predict future results. 
Effective August 1, the Fund will offer Class C shares.

                          NOTES TO FINANCIAL STATEMENTS
                            MAY 31, 1997 (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, 1997, 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 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.
The Fund may issue an unlimited number of shares. The Fund offers Class A shares
sold with a front-end sales charge and Class B shares which 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.

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.

Short-term obligations with a maturity of 60 days or less are valued at
amortized cost.

Portfolio positions which cannot be valued as set forth above are valued at fair
value under procedures approved by the Trustees.

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 distribution fee), 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 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 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.

DEFERRED ORGANIZATION EXPENSES: The Fund incurred expenses of $95,525 in
connection with its organization, initial registration with the Securities and
Exchange Commission and various states, and the initial public offering of its
shares. These expenses were deferred and were amortized on a straight-line basis
over five years.

DISTRIBUTIONS TO SHAREHOLDERS: The Fund declares and records distributions daily
and pays monthly.

The 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 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 0.14% 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 will be 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: Colonial Investment
Services, Inc. (the Distributor), an affiliate of the Adviser, is the Fund's
principal underwriter. During the six months ended May 31, 1997, the Fund has
been advised that the Distributor retained net underwriting discounts of $15,205
on sales of the Fund's Class A shares and received contingent deferred sales
charges (CDSC) of $168,251 on Class B share redemptions.

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% of the average net assets attributable to Class B
shares.

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, 1997, purchases and
sales of investments, other than short-term obligations were $25,791,910 and
$17,590,930, respectively.

Unrealized appreciation (depreciation) at May 31, 1997, based on cost of
investments for federal income tax purposes was approximately:

                 Gross unrealized appreciation                   $ 7,841,000 
                 Gross unrealized depreciation                    (3,698,000)
                                                                 -----------
                         Net unrealized appreciation             $ 4,143,000
                                                                 ===========

Capital loss carryforwards: At November 30, 1996, capital loss carryforwards,
available (to the extent provided in regulations) to offset future realized
gains were approximately as follows:

                   Year of                       Capital loss
                 expiration                      carryforward
                 ----------                      ------------
                    1997                          $   133,000
                    1998                              590,000
                    1999                              364,000
                    2000                              302,000
                    2002                            1,731,000
                    2003                            2,383,000
                                                  -----------
                                                  $ 5,503,000
                                                  ===========

The loss carryforwards expiring in 1997, 1998, and 1999, respectively, 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.

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, 1997.
