Dear Shareholder:

Putnam Tax-Free Health Care Fund's recently concluded fiscal year
coincided with one of the more anxiety-driven times in recent memory.
Uncertainties generated by the Federal Reserve Board's interest-rate
policy, the slowing pace of the economy, and the aftermath of the
presidential election have all contributed to the general sense of
unease.

Typically, in such an environment, investors are drawn to the relative
security of fixed-income investments. In this case, they have also been
increasingly drawn to the tax advantages of municipal bonds, helping to
boost demand in the face of a diminishing supply. Consequently, your
fund, which had been under some pressure during the first half of its
2000 fiscal year, completed the year with solid performance and an
attractive level of tax exempt income.

Seasoned investors realize that uncertainties such as we have recently
experienced are usually transitory. Your fund's manager, Blake Anderson,
successfully positioned the fund to benefit as the market shifted into a
more favorable climate. We are confident that his strategies will enable
it to take full advantage of the opportunities available in fiscal 2001.

Respectfully yours,

/S/ JOHN A. HILL                   /S/ GEORGE PUTNAM, III

REPORT FROM FUND MANAGEMENT

Blake E. Anderson

A number of factors have combined to generate improving results for
Putnam Tax-Free Health Care Fund in the first six months of its fiscal
period, which ended November 30, 2000. The bond market in general has
benefited from a slowing economy since early in the year. Secondly,
strong tax receipts at the federal and state level have provided a
somewhat more favorable background for the health-care sector. Finally,
yields in the sector proved to be attractive during a period of
heightened volatility in the stock market. Together, these conditions
contributed to relatively stable  performance, and your fund enjoyed
modest benefits.

* BONDS BENEFIT FROM VOLATILITY IN EQUITY MARKET

One of the positive influences on fund performance during the six-month
period was the unfavorable situation in the equity market. After several
years of robust returns, investors turned sour on stocks during the
course of 2000, shaken by turbulent markets and concerned about slowing
economic growth. Until December, 2000, the Federal Reserve Board had
viewed inflationary pressures as the chief risk to the economy, and had
tightened monetary policy in response. The consequent economic slowdown
caused many companies to lower their profit forecasts. The  municipal
bond market had already begun to anticipate the beginning of a slowdown
in the economy and delivered better performance to investors who had
maintained their positions.

Footnote reads:
*Based on net assets as of 11/30/00. Holdings will vary over time.

In the context of declining interest rates and investors' pursuit of
safer investments, the AAA/Aaa-rated sector of the municipal market has
benefited the most. Your fund had a large position in AAA/Aaa-rated
bonds, which helped it to achieve a small gain at net asset value while
its yield remained higher than that of most municipal bond funds. While
the lower credit-quality bonds in the portfolio did not perform well,
they helped keep the fund's yield at a very attractive level.

* POLITICAL ISSUES KEEP SECTOR YIELDS HIGH

As we have noted in previous fund reports, both government and private
insurers are under pressure to reduce the growth rate of health-care
spending. This continues to be a main source of risk surrounding
hospital bonds. While demographic developments, such as an aging
population, contribute to rising demand for hospital services, federal
and state governments as well as employers are striving to limit
increases in health-related expenses. The Federal Balanced Budget Act of
1997, in particular, placed new caps on federal reimbursements to
health-care facilities via the Medicare and Medicaid programs.
Meanwhile, health-maintenance organizations have proved to be tough
negotiators on behalf of employers, compelling hospitals to hold the
line on prices.

While the general trend is still toward a lower rate of growth in
health-care spending, the strength of the economy has eased some of the
pressure on hospitals. Thanks to better-than-expected tax receipts, the
federal government has been a bit more generous with reimbursements.
Private employers who are the main buyers of coverage have, in many
cases, been willing to shoulder a portion of rising costs in order to
maintain a level of benefits competitive enough to attract and retain
employees.

Aa/AA -- 5.7%

Footnote reads:
*As a percentage of market value as of 11/30/00. A bond rated Baa/BBB or
 higher is considered investment grade. All ratings reflect Moody's and
 Standard & Poor's descriptions unless noted otherwise; percentages may
 include unrated bonds considered by Putnam Management to be of comparable
 quality. Ratings will vary over time.

Health-care issues figured prominently in the 2000 U.S. election
campaigns at both federal and state levels. Given that both major
political parties' presidential campaigns proposed new health-care
spending, albeit primarily for prescription drugs, there is at least
some possibility that the federal budget surplus could be a source of
health-care funding. We will be monitoring developments in the new
Congress, since many congressional campaigns committed to tighter
regulation of HMOs. We'll watch for the effect this might have on
health-care institutions.

* PORTFOLIO STRUCTURE REMAINS CONSISTENT

Since your fund emphasizes one sector of the municipal bond market, we
focus primarily on our credit research to identify the best
opportunities for a high level of tax-exempt income. We also actively
manage the fund with techniques such as adjusting the credit structure
and duration stance of the portfolio. During the period, the fund
maintained its credit barbell profile, meaning that we have concentrated
assets at high and low credit levels, with little invested in the middle
levels. For example, nearly half of the fund's holdings have the highest
credit rating of AAA/Aaa, a position that is offset by investments in a
combination of BBB/Baa-rated bonds, the lowest investment-grade level,
and in bonds rated below-investment grade. The fund's duration -- its
sensitivity to interest rates -- has been neutral relative to the
market, meaning that we correctly anticipated that long-term interest
rates would be generally stable in most sectors.

In the past six months, there has been little reason to modify the
portfolio. Higher-quality bonds have enjoyed modest price appreciation,
while the lower credit tiers continue to offer an attractive level of
income to compensate for credit risks. This was true not only for
municipal bonds but also for other fixed-income securities.

In these conditions we have been able to add a small number of new
holdings with attractive yield characteristics. At the same time we have
renewed our focus on credit risk. Credit rating downgrades have far
exceeded upgrades in the health-care sector, and unease in the market
has created opportunities. For example, we took advantage of some
opportunities in which risk concerns pushed down the prices of bonds at
the lowest investment-grade tier, making their yields equivalent to
those of lower-rated, high-yield bonds.

* ECONOMIC CONDITIONS MAY REMAIN FAVORABLE

Most of the trends that we have discussed in this report are likely to
remain in place during the second half of the fund's fiscal year. The
contentious issues surrounding health-care funding are likely to remain,
keeping the sector among the most risky but also the highest-yielding
areas of the municipal market. The macroeconomic background should
remain mostly supportive. The Fed continues to adjust monetary policy
seeking stable, non-inflationary growth. Indeed, after deciding not to
raise interest rates at its November and December meetings, the Fed
subsequently cut interest rates in early January, 2001, after the close
of the fund's fiscal period, to prevent further slowing in business
activity. Continued economic growth is positive for employers and for
governments paying healthcare bills. In turn, these conditions may be
positive for hospitals and health-care institutions. At Putnam, our
credit analysts will continue the market for opportunities as economic
conditions and the yield curve change. We will continue to monitor
possibilities to improve the fund's credit profile while maintaining its
yield.

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 11/30/00, there is no guarantee the fund
will continue to hold these securities in the future. The fund
concentrates its investments in one industry and involves more risk than
a fund that invests more broadly.

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 divided by the number of outstanding 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

The Lehman Brothers Municipal Bond Index is an unmanaged list of
approximately 20,000 investment-grade, fixed-rate tax-exempt bonds
representative of the municipal bond market. Securities indexes assume
reinvestment of all distributions and interest payments and do not take
into account brokerage fees or taxes. 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 are determined. All investment and noninvestment 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 sources 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-end funds, a
separate table is provided for each share class.

  (a) Percentages indicated are based on net assets of $184,231,646.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to
      be the most recent ratings available at November 30, 2000 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, 2000. Securities rated by Putnam are
      indicated by "/P" and are not publicly rated.

  (b) The aggregate identified cost on a tax basis is $191,903,443,
      resulting in gross unrealized appreciation and depreciation of
      $5,345,381 and $9,814,399, respectively, or net unrealized depreciation
      of $4,469,018.

(NON) Non-income-producing security.

(RES) Restricted, excluding 144A securities, as to public resale. The
      total market value of restricted securities held at November 30, 2000
      was $13,558,438 or 7.4% of net assets.

(SEG) A portion of these securities were pledged and segregated with the
      custodian to cover margin requirements for futures contracts at November
      30, 2000.

      The rates shown on IFB and IF COP, 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, 2000.

NOTES TO FINANCIAL STATEMENTS
November 30, 2000 (Unaudited)

Note 1
Significant accounting policies

Putnam Tax-Free Health Care Fund (the "fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The fund seeks as high a level of current
income exempt from federal income tax as Putnam Investment Management,
LLC, ("Putnam Management"), the fund's manager, a wholly-owned
subsidiary of Putnam Investments, Inc., believes is consistent with
preservation of capital by investing primarily in a portfolio of
tax-exempt securities in the health care sector of the tax-exempt
securities market.

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 accounting principles generally accepted in the United States of
America and requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities of the financial
statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period. 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.
Restricted securities are stated at fair value following procedures
approved by the Trustees. Such valuations and procedures are reviewed
periodically 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). Gains or losses on securities sold are determined
on the identified cost basis.

Interest income is recorded on the accrual basis.

C) 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. When the contract is closed, the fund records a
realized gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was
closed. Realized gains and losses on purchased options are included in
realized gains and losses on investment securities.

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.

D) 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 May 31, 2000, the fund had a capital loss carryover of approximately
$2,265,000 available to offset future capital gains, if any. The amount
of the carryover and the expiration dates are:

Loss Carryover    Expiration
--------------    ------------------
    $  277,000    May 31, 2007
     1,988,000    May 31, 2008

E) Distributions to shareholders Distributions to shareholders from net
investment income are recorded by the fund on the ex-dividend date.
Capital gain distributions, if any, are recorded on the ex-dividend date
and paid at least annually. 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.

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, original issue discount 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. Such fee is based on the annual rate of 0.70% of average
weekly net assets.

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.

Under the subcustodian contract between the subcustodian bank and PFTC,
the subcustodian bank has a lien on the securities of the fund to the
extent permitted by the fund's investment restrictions to cover any
advances made by the subcustodian bank for the settlement of securities
purchased by the fund. At November 30, 2000, the payable to the
subcustodian bank represents the amount due for cash advance for the
settlement of a security purchased.

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.

The fund has entered into an arrangement with PFTC whereby credits
realized as a result of uninvested cash balances are used to reduce a
portion of the fund's expenses. For the six months ended November 30,
2000, the fund's expenses were reduced by $58,028 under these
arrangements.

Each Trustee of the fund receives an annual Trustee fee, of which $565
has been allocated to the fund, and an additional fee for each Trustees
meeting attended. 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
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 a 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.

Notes 3
Purchase and sales of securities

During the year ended May 31, 2000, cost of purchases and proceeds from
sales of investment securities other than short-term investments
aggregated $24,805,350 and $23,610,400, respectively. There were no
purchases and sales of U.S. government obligations.

Note 4
New accounting pronouncement

In November 2000, the AICPA issued a revised Audit and Accounting Guide,
Audits of Investment Companies, which is effective for fiscal years
beginning after December 15, 2000. The revised Guide will require the
fund to amortize premium and accrete discount on all fixed-income
securities, and classify as interest income gains and losses realized on
paydowns on mortgage-backed securities which are presently included in
realized gain/loss. Adopting these accounting principles will not affect
the fund's net asset value, but will change the classification of
certain amounts between interest income and realized and unrealized
gain/loss in the Statement of operations. The fund has not at this time
quantified the impact, if any, resulting from the adoption of this
principle on the financial statements.

Note 5
Change in independent accountants
(unaudited)

Based on the recommendation of the Audit Committee of the fund, the
Board of Trustees has determined not to retain PricewaterhouseCoopers
LLP as this funds' independent accountants and voted to appoint KPMG LLP
for the fund's fiscal year ended May 31, 2001. During the two previous
fiscal years, PricewaterhouseCoopers LLP audit reports contained no
adverse opinion or disclaimer of opinion; nor were its reports qualified
or modified as to uncertainty, audit scope, or accounting principle.
Further, in connection with its audits for the two previous fiscal years
and through July 24, 2000, there were no disagreements between the fund
and PricewaterhouseCoopers LLP on any matter of accounting principles or
practices, financial statement disclosure or auditing scope or
procedure, which if not resolved to the satisfaction of
PricewaterhouseCoopers LLP would have caused it to make reference to the
disagreements in its report on the financial statements for such years.


RESULTS OF OCTOBER 5, 2000 SHAREHOLDER MEETING
(Unaudited)

An annual meeting of shareholders of the fund was held on October 5,
