Dear Shareholder:

The rush of foreign investors to the safety of U.S. Treasury bonds in
recent months has driven prices on these securities markedly higher.
Because of the inverse relationship of yields to prices, yields on 30-year
Treasuries have declined to virtually the same level as those on long-term
municipals. This near parity has made tax-exempt bonds unusually
attractive for U.S. investors. 

The increased demand for tax-exempt bonds, however, is not likely to be
matched by a new supply; most issuers have already refinanced outstanding
bonds at lower rates and the flow of refundings has fallen off markedly.
Thus one of the greatest challenges for Fund Manager Richard Wyke may
continue to be that of finding securities that meet Putnam Investment
Grade Municipal Trust's strict selection criteria. 

In the following report from Rick, you will find details of these
developments and other aspects of the fund's performance during the fiscal
year that closed on November 30, 1998. He also offers his views on
prospects for the fiscal year that just began. 

Respectfully yours, 

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
January 20, 1999



Report from the Fund Manager
Richard P. Wyke

After a turbulent autumn, the municipal bond market has calmed down and
even slightly outperformed the Treasury market. Long-term municipal bond
yields are approximately the same as the 30-year Treasury bond yield --
exhibiting a remarkable level of cheapness against Treasuries. This ratio
dropped to 97% during November, but by the end of the month, it had
returned to 100%. Considering that this ratio stood between 85% and 95%
for most of the 1990s, today's relationship is quite unusual and, in our
opinion, indicates a buying opportunity.

It is within this environment that Putnam Investment Grade Municipal Trust
continued to produce high current income exempt from federal taxes as well
as a solid total return. For the 12 months ended November 30, 1998, the
fund's common shares earned total returns of 6.98% at net asset value and
8.73% at market price. For complete performance information, please see
pages 8 and 9.

* FLIGHT TO QUALITY DRIVES TREASURY YIELDS DOWN

Municipal bonds arrived at these unprecedented yield ratios after a string
of international problems set off the stock market volatility and the bond
market rallies. As foreign investors and hedge fund investors panicked
about plummeting stock markets, they began the flight to quality --
selling hedge funds and emerging-markets funds in favor of the safety of
U.S. Treasury bonds. This buying drove up the prices of Treasuries while
pushing down their yields. Since foreign investors do not benefit from the
tax advantages of municipal bonds, prices in this market did not rise as
much as those of Treasuries. For the past few months, municipal bond
yields have been extremely close or equal to Treasury yields, making
municipal bonds an exceptional investment choice for U.S. investors.

* REFUNDINGS SLOW; MUNICIPAL SUPPLY BEGINS TO MODERATE

Normally, when interest rates fall, refundings boost the bond supply. But
rates have been low for some time; most issuers have already completed
their refundings and we expect that the supply of new issues will slow --
a positive factor for municipal bond prices. The calendar of municipal
bond sales usually slows during the holiday season as well.

The yield relationship of Treasury and municipal securities is also
contributing to the decline in supply. Since Treasury yields fell so
dramatically relative to municipal yields, the Treasury escrows used in
prerefundings are not adequate to pay off the municipal issues.

* SEARCHING FOR INCOME OPPORTUNITIES

Since last spring, one of our challenges has been to deliver an attractive
level of income in a market in which yields have fallen. We have tried to
meet this challenge by exploring attractive opportunities in key industry
sectors, including utilities, transportation and health care.

Transportation issues have fared well over the past year, since capacity
has remained steady and fuel costs have been low. This combination of
factors has enabled airlines to increase prices and helped support airport
revenues. For example, Denver (Colorado) City and County Airport revenue
bonds with a Baa1 rating have generated steady income for some time. As
the economy slows down, however, this sector may need closer scrutiny.

*As a percentage of market value as of 11/30/98. A bond rated Baa or
 higher is considered investment grade. All ratings reflect 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.


Another strategy we have used has been to extend call protection as we
make new investments. This is done by purchasing noncallable bonds or
bonds with distant call dates. Callable bonds carry the option of being
redeemed, or called away, by the issuer at a certain future date. Bonds
are normally called away if interest rates are lower than they were when
the bonds were originally issued. By avoiding callable bonds, the
portfolio has a better chance of maintaining a certain level of income.

The potential for declining income may be offset in part by leveraging, a
strategy that has been useful in enhancing the trust's income. The fund
issues preferred shares to institutional short-term investors at low rates
and reinvests the proceeds in higher-paying longer-term bonds. The effect
is a more positive cash flow for the fund's common shareholders. 

* INTEREST-RATE CUTS SEND POSITIVE MESSAGE 

It is reassuring to know that we have a Federal Reserve Board that is
prepared to step in to stabilize the markets when a crisis occurs. As of
period's end, the Fed has cut interest rates three times -- totaling 75
basis points -- sending a positive message to the world and Wall Street.
With the Fed's encouragement, we anticipate a slowing, but still strong
U.S. economy supported by consumers' willingness to spend. And on the
local level, cities and towns are still enjoying increases in tax
collections, always a positive aspect of the municipal bond market.
Looking ahead, the municipal bond market appears stable, offering superb
value for tax-conscious investors.

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 11/30/98, there is no guarantee the fund will
continue to hold these securities in the future.

TERMS AND DEFINITIONS

Total return shows how the value of the fund's common 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 one common
share. 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 assumes reinvestment of all distributions
and interest payments and does not take in account brokerage fees or
taxes. Securities in the fund do not match those in the indexes 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) Percentages indicated are based on net assets of $389,621,549.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to be the most recent ratings available at
      November 30, 1998 for the securities listed. Ratings are generally ascribed to securities at the time of issuance.
      While the agencies may from time to time revise such ratings, they undertake no obligation to do so, and the ratings
      do not necessarily represent what the agencies would ascribe to these securities at November 30, 1998. Securities
      rated by Putnam are indicated by "/P" and are not publicly rated. Ratings are not covered by the Report of
      independent accountants.

  (b) The aggregate identified cost on a tax basis is $350,449,030, resulting in gross unrealized appreciation and
      depreciation of $24,935,278 and $1,932,834, respectively, or net unrealized appreciation of $23,002,444.

      held at November 30, 1998 was $7,068,688 or 1.8% of net assets.

      The rates shown on IFB's, which are securities paying interest rates that vary inversely to changes in the
      market interest rates, and VRDN's are the current interest rates at November 30, 1998.

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. 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.

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 November
30, 1998 was 3.20%. 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. These
differences include temporary and permanent differences of dividends
payable, defaulted bond interest, market discount, and prior year straddle
loss deferrals. 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. For the year ended
November 30, 1998, the fund reclassified $36,128 to increase undistributed
net investment income and $36,128 to decrease accumulated net realized
losses. The calculation of net investment income per share in the
financial highlights table excludes these adjustments.

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 (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.

F) 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 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 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 year ended November 30, 1998, fund expenses were reduced by
$30,053 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 $550 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 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.

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 year ended November 30, 1998, purchases and sales of investment
securities other than short-term investments aggregated $55,521,330 and
$58,622,225, 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 November 30, 1998, no such restrictions have been
placed on the fund.
