Investors are becoming skittish about the sky-high returns on equity 
funds and are beginning to seek some less-risky tax-free income; yields 
on municipal bonds hover around an attractive 6 percent range, and 
investors in some tax-high states can do better on an after-tax basis 
investing in municipals than in Treasuries."

Dear Shareholder:

One of the fascinating things about market watching is that you can 
never tell what's going to trigger a defining event. Often what seems 
like a defining event one moment is history the next. Who would have 
guessed, for example, that a flat-tax proposal would swirl out of the 
presidential primary election campaign to douse the municipal bond 
market, only to blow away just as the rest of the bond market was 
stumbling on statistics suggesting that inflation might flare up?

These were some of the challenges facing Fund Manager Michael F. 
Bouscaren during the first half of Putnam Investment Grade Municipal 
Trust's fiscal year, the six months ended May 31, 1996. Mike handled 
them with his usual aplomb as the results on the following pages reveal. 

Besides having the luxury of leaving the day-to-day details to Mike, 
shareholders with a long-term investment perspective have the added 
advantage of being able to let such events run their course without 
undue concern. 

Respectfully yours, 

/S/George Putnam

George Putnam

Chairman of the Trustees

July 17, 1996



Report from the Fund Manager
Michael F. Bouscaren


As Putnam Investment Grade Municipal Trust began fiscal 1996, slowing 
economic growth, low interest rates, and low inflation had created an 
appealing environment for fixed-income investments. However, by the 
fiscal year's midpoint on May 31, 1996, the bond market was dancing to a 
different beat. Stronger-than-expected employment growth had fueled 
fears of inflation, signaling a possible end to the Federal Reserve 
Board's program of lowering short-term interest rates and bringing the 
10-month bond market rally to an abrupt halt.

Your fund was poised to adapt to this changing economic environment. 
Although sector weightings and core holdings remained essentially 
unchanged throughout the period, we maximized the fund's potential by 
exploring opportunities nationwide, purchasing bonds in states in which 
economic activity was accelerating and maintaining those holdings that 
continued to provide combinations of attractive income and possible 
appreciation. For the semiannual period, the fund's common shares 
provided a total return of -2.03% at net asset value and 1.84% at market 
price. 

* DURATION ADJUSTMENTS HELP FUND RESPOND TO CHANGING CONDITIONS

Adjusting duration in response to interest-rate trends is an important 
component of the fund's strategy. Duration is a measure of the 
portfolio's maturity structure and reflects the price sensitivity of 
portfolio holdings to changes in interest rates. Typically, bonds with 
longer maturities are more sensitive to these changes and, as a result, 
may offer greater potential for appreciation when rates are declining. 
Since the direction of interest rates was uncertain at the period's 
start, we reviewed the portfolio duration in the expectation of a 
rising-rate environment -- something of a worst-case scenario. 

At the beginning of the period, the portfolio's duration was a 
relatively long 10 years. In light of recent volatility, it seemed 
prudent to us to reduce this to 7 1/2 years, and we were able to 
accomplish the shift by period's end. The move proved timely; it 
softened the impact of the market decline as bond prices readjusted to 
the prospect of a stronger economy. 

More recently, we've seen indications that this may not, in fact, be the 
case; the employment and inflation data that sparked the market downward 
appear to reflect short-term anomalies rather than true forecasts of a 
change in direction. However, whether or not the Fed makes a change in 
its interest-rate policy, our decision to acquire additional short- to 
intermediate-term municipal bonds will bolster the fund's level of call 
protection -- another important consideration in a volatile rate 
environment. 

* FUND BENEFITS FROM PROSPERING STATE ECONOMIES

We are considering selling additional New York, New Jersey, and 
Pennsylvania bonds and increasing the fund's holdings in Texas and 
California securities. The California and Texas economies are currently 
growing faster than the national average, the result of flourishing new 
businesses, rising employment rates, and accelerating residential 
construction. When a state economy is strengthening, investor 
perceptions of its bonds improve, the risk of any interruption in 
interest payments lessens, and demand for the bonds may well increase. 
This sequence of events, in turn, can lead to higher prices for the 
bonds.

Bonds issued to support the new Denver International Airport remain as a 
significant portfolio position because of their favorable income and 
credit features. Current law prohibits many municipal issuers from 
refunding outstanding bonds with lower-cost debt. However, issuers do 
have the ability to make tender offers, giving bondholders the 
opportunity to sell securities back to them at an agreed-upon price. 
Issuers generally must pay bondholders above-market prices to persuade 
them to tender their higher-coupon securities. Although there was an 
offer to tender higher-coupon Denver airport bonds in March, we did not 
offer the bonds for sale, since we perceived the tender prices to be 
unattractive. 

Some of your fund's income is generated by the selective use of 
leveraging strategies. With this approach, the fund issues preferred 
shares that pay dividends at prevailing short-term rates. These shares 
are sold to corporate and institutional investors; the resulting assets 
are then invested in longer-term bonds with higher yields. The 
difference between the rates paid to holders of preferred shares and the 
rates earned by the fund augment the flow of income to holders of common 
shares. Since the yield curve steepened during the reporting period, 
resulting in a profitable spread between short- and long-term yields, 
the fund's leveraging strategies proved to be beneficial. 

* FADING FLAT-TAX FEARS HELP IMPROVE INVESTOR PERSPECTIVES

During the past several months, investors have been particularly 
sensitive to the potential effects of the flat-tax proposal being 
considered by Congress. In its purest form, the flat tax would deprive 
municipal bonds of their advantage as tax-exempt investments. Although 
such discussions have influenced the municipal market for more than a 
year now, investor concerns and fears have recently subsided, since the 
flat tax did not appear to be a near-term event after all. Although we 
expect discussions of broader tax reform to reappear this fall as the 
presidential election nears, our current assessment is that any radical 
changes to the tax code now appear unlikely. As a result, investors may 
rediscover overlooked tax-advantaged opportunities. An increase in 
investor demand is likely to have a beneficial effect on municipal bond 
valuations.

higher is considered investment grade. All ratings reflect Moody's 
descriptions, unless noted otherwise.These may include unrated bonds 
judged by Putnam management to be of considerable quality. Ratings 
will vary over time.

* GUARDED APPROACH NECESSARY

A steadily growing economy presents a challenging environment for fixed-
income investing and clearly requires a more cautious strategy. Careful 
attention to bond structure and emphasis on larger, well-known issuers 
will play an important role in enhancing the price stability and 
liquidity of your fund for the remainder of its fiscal period. 

On a cheerier note, the summer months have historically been friendly to 
municipal bonds, since cash from interest payments and bond calls is 
frequently reinvested in the tax-exempt market. New-issue supply over 
the next few months is not expected to keep pace with this year's 
potential demand, creating the opportunity for a favorable supply/demand 
imbalance. 

Sustained interest from nontraditional buyers, including banks and 
insurance companies, could provide further support. In addition, as the 
risk of a flat tax diminishes, municipal returns could continue to 
outpace those of taxables throughout the course of the year.


The views expressed here are exclusively those of Putnam Management. 
They are not meant as investment advice. Although the described holdings 
were viewed favorably as of 5/31/96, there is no guarantee the fund will 
continue to hold these securities in the future.

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, may include bonds different from those in 
the fund, and may pose different risks than the fund. 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.

Notes to financial statements
May 31, 1996 (Unaudited)


Note 1 
Significant accounting policies

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 ("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. Certain amounts from the prior year have been reclassified to 
conform with their current year presentation.

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.

B) Determination of net asset value Net asset value of the common shares 
is determined by dividing the value of all assets of the fund (including 
accrued interest) less all liabilities (including accrued expenses and 
undeclared dividends on remarketed preferred shares) and the liquidation 
value of any outstanding remarketed preferred shares, by the total 
number of common shares outstanding.

C) 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.

D) Futures and options contracts The fund may use futures and options 
contracts to hedge against changes in the values of securities the fund 
owns or expects to purchase. The fund may also write options on 
securities it owns or in which it may invest to increase its current 
returns.

The potential risk to the fund is that the change in value of futures 
and options contracts may not correspond to the change in value of the 
hedged instruments. In addition, losses may arise from changes in the 
value of the underlying instruments, if there is an illiquid secondary 
market for the contracts, or if the counterparty to the contract is 
unable to perform.

Futures contracts are valued at the quoted daily settlement prices 
established by the exchange on which they trade. Exchange traded options 
are valued at the last sale price, or if no sales are reported, the last 
bid price for purchased options and the last ask price for written 
options. Options traded over-the-counter are valued using prices 
supplied by dealers.

E) 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. Therefore, no provision has
been made for federal taxes on income, capital gains or unrealized 
appreciation on securities held and for excise tax on income and capital 
gains.

F) Distributions to shareholders Distributions to common and preferred 
shareholders are recorded by the fund on the ex-dividend 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, 1996 was 3.54%. 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.

G) Amortization of bond premium and 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 effective yield method.

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 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.

Trustees of the fund receive an annual Trustees fee of $840 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 adopted a Trustee Fee Deferral Plan (the "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 invested in 
certain Putnam funds until distribution in accordance with the Plan.

Custodial functions for the fund's assets are provided by Putnam 
Fiduciary Trust Company (PFTC), a wholly-owned 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, 1996, fund expenses were reduced by 
$47,853 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.

Note 3 
Purchase and sales of securities

During the six months ended May 31, 1996, purchases and sales of 
investment securities other than short-term investments aggregated 
$380,317,645 and $403,394,684 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. 

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, 1996, no such 
restrictions have been placed on the fund.
