Dear Shareholder:

Rising interest rates are not good news for bond investors, but the impact
of this news in the municipal bond market was somewhat deflected in the
face of steady demand for municipals and shrinking supply. Recently,
long-term Treasuries edged past 6% for the first time in more than a year.
Long-term municipal bond yields have risen too but not as dramatically,
illustrating the resistance of the municipal market to a rise in interest
rates. This relative stability in an uncertain rate environment has
enabled Putnam Investment Grade Municipal Trust to deliver solid
performance and attractive levels of income for the six months ended May
31, 1999.

Total return for 6 months ended 5/31/99

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

Past performance is no indication of future results. Performance
information for longer periods begins on page 6.


* SUPPLY LOW; DEMAND REMAINS STRONG

This year's climbing interest rates continued to take their toll on
new-issue volume, as the national supply fell 40% compared with the spring
of 1998. On the demand side, cash flow into municipal bonds has increased
- -- a by-product of a volatile stock market and investors' need to
rebalance their portfolios. The ensuing supply/demand relationship is
positive for the municipal bond market and should help support bond prices
in a rising interest-rate environment.


[GRAPHIC OMITTED: horizontal bar chart TOP INDUSTRY SECTORS]

TOP INDUSTRY SECTORS*

Utilities             24.9%

Transportation        22.4%

Health care           16.5%

Housing               11.1%

Education              7.1%

Footnote reads:
*Based on net assets as of 5/31/99. Holdings will vary over time.


As interest rates have moved up, Fund Manager Richard Wyke has begun the
process of increasing maturities incrementally in order to lock in higher
yields. He cannot predict when interest rates will reach their peak, of
course, but he does believe that this is a good time to implement this
strategy.

* EMPHASIS ON TRANSPORTATION, UTILITY SECTORS

Rick has identified two industry sectors that continue to provide
rewarding results: transportation and utilities. The economy's strength
affords solid underpinnings for the transportation industry -- especially
airlines and air freight. As an example, Denver City & County Airport
revenue bonds continue to provide solid income for the fund. A record
number of passengers traveled through this airport in 1998, and net income
and revenues increased as well.


"Though municipal bonds aren't the conspicuous value they were last year --
when yields on Treasury bonds and municipals were nearly identical -- tax-free
bonds are still attractive."

- -- Forbes, April 5, 1999


In the utility sector, Rick believes that while deregulation and
restructuring are still in the early stages, the prices of many municipal
electric utility bonds have already been fully discounted and now
represent significant value. For example, two Nevada revenue bond issues,
Southwest Gas Company and Nevada Power Company, contributed to the fund's
positive performance. Nevada Power has a strong service territory with a
concentration of nonnuclear power assets. The proposed merger of Southwest
Gas with ONEOK would create the largest independent gas distributor in the
United States. While these holdings, along with others discussed in this
report, were viewed favorably at the end of the period, all are subject to
review and adjustment in accordance with the fund's investment strategy
and may vary in the future.


[GRAPHIC OMITTED: pie chart CREDIT QUALITY OVERVIEW]

CREDIT QUALITY OVERVIEW*

A -- 11.5%

Baa/BBB -- 31.1%

Ba/BB and below -- 8.7%

Aaa/AAA -- 45.4%

Aa/AA -- 3.3%

Footnote reads:
* As a percentage of market value as of 5/31/99. A bond rated Baa or higher
  is considered investment grade. All ratings reflect Standard & Poor's and
  Moody's descriptions unless noted otherwise; percentages may include
  unrated bonds considered by Putnam Management to be of comparable quality.
  Ratings will vary over time.


* OUTLOOK: INFLATION SLIGHTLY HIGHER BUT STILL LOW

With some indications that inflation may be starting to rise, the consumer
price index is moving toward an annualized core inflation rate of
approximately 2%. Since inflation in 1998 was practically nonexistent, a
move to 2% may seem tremendous but is actually still well below the 4%
that has generally been considered average. Despite some signs of
inflation, we still live in a strong economy in a deflationary world in
which many prices are falling. Just look at online stock trading prices
and the discounts available from online bookstores for evidence of
deflation.

It is important to keep inflation in mind when investors determine what
constitutes a good rate of return. Simply put, a yield of 6% with 2%
inflation is still a solid return, especially once the psychology of an
advancing stock market begins to shift. When that happens, a steady 4%
after-tax, after-inflation yield looks exceptionally good in addition to
the benefit of substantially less volatility.

Respectfully yours,

viewed favorably as of 5/31/99, there is no guarantee the fund will

1 Capital gains, if any, are taxable for federal and, in most cases, state
  tax purposes. For some investors, investment income may also be subject to
  the federal alternative minimum tax. Investment income may be subject to
  state and local taxes.

2 Income portion of most recent distribution, annualized and divided by
  NAV or market price at end of period.

3 Assumes maximum 39.6% federal tax rate. Results for investors subject to
  lower tax rates would not be as advantageous.



Terms and definitions

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested all
distributions in the fund.

Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities and the net assets allocated to remarketed preferred shares,
divided by the number of outstanding common shares.

Market price is the current trading price of one share of the fund. Market
prices are set by transactions between buyers and sellers on the New York
Stock Exchange.


Comparative benchmarks

Lehman Brothers Municipal Bond Index is an unmanaged list of long-term
fixed-rate investment-grade tax-exempt bonds representative of the
municipal bond market. The index does not take into account brokerage
commissions or other costs and may pose different risks than the fund.
Securities in the fund do not match those in the index and performance of
the fund will differ. It is not possible to invest directly in an index.

Consumer price index (CPI) is a commonly used measure of inflation; it
does not represent an investment return.



A guide to the financial statements

These sections of the report constitute the fund's financial
statements.

The fund's portfolio lists all the fund's investments and their values as
of the last day of the reporting period. Holdings are organized by asset
type and industry sector, country, or state to show areas of concentration
and diversification.

Statement of assets and liabilities shows how the fund's net assets and
share price is determined.  All investment and non-investment assets are
added together.  Any unpaid expenses and other liabilities are subtracted
from this total.  The result is divided by the number of shares to determine
the net asset value per share, which is calculated separately for each class
of shares. (For funds with preferred shares, the amount subtracted from total
assets includes the net assets allocated to remarketed preferred shares.)

Statement of operations shows the fund's net investment gain or loss for the
reporting period. This is determined by adding up all the fund's earnings --
from dividends and interest income -- and subtracting its operating expenses.
This statement also lists any net gain or loss the fund realized on the sales
of its holdings and -- for holdings that remain in the portfolio -- any change
in unrealized gains or losses over the period.

Statement of changes in net assets shows how the fund's net assets were
affected by distributions to shareholders and by changes in the number of the
fund's shares. It lists distributions and their sources (net investment income
or realized capital gains) over the current reporting period and the most
recent fiscal year-end. The distributions listed here may not match the
amounts listed in the Statement of Operations because the distributions are
determined on a tax basis and may be paid in a different period from the one
in which they were earned.

Financial highlights provide an overview of the fund's investment results,
per-share distributions, expense ratios, net investment income ratios and
portfolio turnover in one summary table, reflecting the five most recent
reporting periods. In a semiannual report, the highlight table also includes
the current reporting period. For open-ended funds, a separate table is
provided for each share class.

Notes to financial statements
May 31, 1999 (Unaudited)

Note 1
Significant accounting policies

Putnam Investment Grade Municipal Trust (the "fund") is registered under
the Investment Company Act of 1940, as amended, as a diversified,
closed-end management investment company. The fund's investment objective
is to provide as high a level of current income exempt from federal income
tax as is believed to be consistent with preservation of capital. The fund
intends to achieve its objective by investing in a diversified portfolio
of tax-exempt municipal securities that Putnam Investment Management Inc.
("Putnam Management"), the fund's Manager, a wholly-owned subsidiary of
Putnam Investments Inc., believes do not involve undue risk to income or
principal. Under normal market conditions, the fund will invest at least
80% of its total assets in tax-exempt municipal securities rated
"investment grade" at the time of investment or, if not rated, determined
by Putnam Management to be of comparable quality.

The following is a summary of significant accounting policies consistently
followed by the fund in the preparation of its financial statements. The
preparation of financial statements is in conformity with generally
accepted accounting principles and requires management to make estimates
and assumptions that affect the reported amounts of assets and
liabilities. Actual results could differ from those estimates.

A) Security valuation Tax-exempt bonds and notes are stated on the basis
of valuations provided by a pricing service, approved by the Trustees,
which uses information with respect to transactions in bonds, quotations
from bond dealers, market transactions in comparable securities and
various relationships between securities in determining value.

Short-term investments having remaining maturities of 60 days or less are
stated at amortized cost, which approximates market value and other
investments including restricted securities are stated at fair market
value following procedures approved by the Trustees.

B) Security transactions and related investment income Security
transactions are accounted for on the trade date (date the order to buy or
sell is executed). Interest income is recorded on the accrual basis.

C) Federal taxes It is the policy of the fund to distribute all of its
income within the prescribed time and otherwise comply with the provisions
of the Internal Revenue Code applicable to regulated investment companies.
It is also the intention of the fund to distribute an amount sufficient to
avoid imposition of any excise tax under Section 4982 of the Internal
Revenue Code of 1986, as amended. Therefore, no provision has been made
for federal taxes on income, capital gains or unrealized appreciation on
securities held nor for excise tax on income and capital gains.

At November 30, 1998, the fund had a capital loss carryover of
approximately $4,259,000 available to offset future capital gains, if any.
The amount of the carryover and the expiration dates are:

Loss Carryover                   Expiration
- --------------               -----------------
    $1,985,000               November 30, 2004
       612,000               November 30, 2005
     1,662,000               November 30, 2006

D) Distributions to shareholders Distributions to common and preferred
shareholders are recorded by the fund on the ex-dividend date. If the
market price of your fund's shares is equal to or exceeds their net asset
value on the payment date, you will be issued shares of the fund at a
value equal to the higher of the net asset value or 95% of the market
price on that date. Dividends on remarketed preferred shares become
payable when, as and if declared by the Trustees. Each dividend period for
the remarketed preferred shares is generally a seven-day period. The
applicable dividend rate for the remarketed preferred shares on May 31,
1999 was 3.245%. 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
carryovers) under income tax regulations.

E) Determination of net asset value Net asset value of the common shares
is determined by dividing the value of all assets of the fund less all
liabilities and the liquidation preference of any outstanding remarketed
preferred shares, by the total number of common shares outstanding.

F) Amortization of bond premium and accretion of bond discount Any premium
resulting from the purchase of securities in excess of maturity value is
amortized on a yield-to-maturity basis. Discounts on zero coupon bonds and
original issue bonds are accreted according to the yield-to-maturity
basis.

Note 2
Management fee, administrative
services, and other transactions

Compensation of Putnam Management for management and investment advisory
services is paid quarterly based on the average net assets of the fund,
including those allocated to the remarketed preferred shares. Such fee is
based on the annual rate of 0.70% of the average weekly net assets.

If dividends payable on remarketed preferred shares during any dividend
payment period plus any expenses attributable to remarketed preferred
shares for that period exceed the fund's net income attributable to the
proceeds of the remarketed preferred shares during that period, then the
fee payable to Putnam for that period will be reduced by the amount of the
excess (but not more than 0.70% of the liquidation preference of the
remarketed preferred shares outstanding during the period).

The fund reimburses Putnam Management an allocated amount for the
compensation and related expenses of certain officers of the fund and
their staff who provide administrative services to the fund. The aggregate
amount of all such reimbursements is determined annually by the Trustees.

Custodial functions for the fund's assets are provided by Putnam Fiduciary
Trust Company (PFTC), a subsidiary of Putnam Investments, Inc. Investor
servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

For the six months ended May 31, 1999, fund expenses were reduced by
$12,074 under expense offset arrangements with PFTC. Investor servicing
and custodian fees reported in the Statement of operations exclude these
credits. The fund could have invested a portion of the assets utilized in
connection with the expense offset arrangements in an income producing
asset if it had not entered into such arrangements.

Each Trustee of the fund receives an annual Trustee fee, of which $530 has
been allocated to the fund, and an additional fee for each Trustee's
meeting attended. Trustees who are not interested persons of Putnam
Management and who serve on committees of the Trustees receive additional
fees for attendance at certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of
Trustees Fees payable on or after July 1, 1995. The deferred fees remain
in the fund and are invested in certain Putnam funds until distribution in
accordance with the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as Trustee for at least five years. Benefits under the Pension Plan
are equal to 50% of the Trustee's average total retainer and meeting fees
for the three years preceding retirement. Pension expense for the fund is
included in Compensation of Trustees in the Statement of operations.
Accrued pension liability is included in Payable for compensation of
Trustees in the Statement of assets and liabilities.

Note 3
Purchase and sales of securities

During the six months ended May 31, 1999, purchases and sales of
investment securities other than short-term investments aggregated
$36,319,869 and $23,175,895, respectively. There were no purchases and
sales of U.S. government obligations. In determining the net gain or loss
on securities sold, the cost of securities has been determined on the
identified cost basis.

Note 4
Remarketed preferred shares

The Series A remarketed preferred shares are redeemable at the option of
the fund on any dividend payment date at a redemption price of $100,000
per share, plus an amount equal to any dividends accumulated on a daily
basis but unpaid through the redemption date (whether or not such
dividends have been declared) and, in certain circumstances, a call
premium.

Additionally, the fund has authorized a separate series of 2,000 Serial
Remarketed Preferred shares, which are issuable only under certain
conditions in exchange for Series A shares. No Serial Remarketed Preferred
shares are currently outstanding.

It is anticipated that dividends paid to holders of remarketed preferred
shares will be considered tax-exempt dividends under the Internal Revenue
Code of 1986. To the extent that the fund earns taxable income and capital
gains by the conclusion of a fiscal year, it will be required to apportion
to the holders of the remarketed preferred shares throughout that year
additional dividends as necessary to result in an after-tax equivalent to
the applicable dividend rate for the period.

Under the Investment Company Act of 1940, the fund is required to maintain
asset coverage of at least 200% with respect to the remarketed preferred
shares as of the last business day of each month in which any such shares
are outstanding. Additionally, the fund is required to meet more stringent
asset coverage requirements under terms of the remarketed preferred shares
and the shares' rating agencies. Should these requirements not be met, or
should dividends accrued on the remarketed preferred shares not be paid,
the fund may be restricted in its ability to declare dividends to common
shareholders or may be required to redeem certain of the remarketed
preferred shares. At May 31, 1999, no such restrictions have been placed
on the fund.
