Dear Shareholder:

The markets continued to provide their share of challenges and
opportunities as your fund closed its books on the first half of fiscal
year 2000. In the following report, the fund's managers discuss
performance for the period and prospects for the months ahead.

This is the last letter to you and the other shareholders of Putnam Tax
Smart Equity Fund that I will be signing. After more than 30 years as
Chairman of the Trustees and President of the Putnam Funds, the time has
come for me to step aside.  As of July 1, 2000, John Hill will become
Chairman. John is currently an independent Trustee and has served on the
board for the past 14 years. In addition, my son, George Putnam, III,
will take on the role of President. I am confident that the leadership
of the funds will be in exceptionally strong hands.

I will become Chairman Emeritus, remain a Putnam shareholder, and stay
in close touch with the funds. It has been my privilege to serve you.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
June 21, 2000


REPORT FROM THE FUND MANAGERS

Robert R. Beck
Paul Marrkand
Matthew Halperin
Michael K. Arends

For the six months ended April 30, 2000, Putnam Tax Smart Equity Fund's
focus on solid companies in growing sectors proved beneficial despite
the challenges of a volatile stock market. For most of the period, U.S.
financial markets were delivering robust -- and in many cases
record-breaking -- returns. Although this momentum reversed sharply in
the final weeks of the period,  your fund delivered solid returns and
handily outperformed its benchmark, the S&P 500 Index.

Total return for 6 months ended 4/30/00

* VOLATILITY CONTINUES TO PLAGUE MARKETS

Beginning in mid March, a number of factors combined to create weakness
in the stock market. This eventually led to sharp volatility, with the
major indexes experiencing some of their largest point drops on record
during April. Perhaps most alarming to investors was an April 14 report
on the consumer price index that indicated inflation may be on the rise.
This report was a catalyst for investors who had been sorting through
other potentially negative news, including the Microsoft antitrust
verdict, some disappointing earnings announcements, and press reports
that many stocks, especially in the technology sector, were overvalued.
By the end of April, the Dow had lost more than 12% since its peak in
January, the S&P had dropped more than 11% since its March 24 peak, and
the Nasdaq had declined more than 32% since its high on March 10.

*Based on net assets as of 4/30/00. Holdings will vary over time.


The performance of many portfolio holdings was dampened in the April
market downturn. However, it is important to note that such volatility
is a natural part of stock market investing and we believe the market,
the economy, and the fund's holdings remain fundamentally strong. In
fact, the recent market activity has given us an unusual opportunity to
purchase shares of solid companies at attractively low prices. This was
especially beneficial for your fund, as its strategy is to target stocks
that may be priced below their long-term worth.

* TECH STOCKS PLAY MAJOR ROLE IN FISCAL 2000

During the semiannual period, the pervasive influence of technology,
especially the Internet, touched almost every growth sector. The
inclusion of Microsoft and Intel in the Dow and the addition of Internet
stocks Yahoo! and America Online to the S&P 500 Index illustrated the
growing influence of technology in today's economy. In the past year,
approximately 150,000 new users worldwide went online each day and more
than 61 million U.S. homes are now connected to the Internet. We are
pleased to report that your fund took full advantage of opportunities in
the technology sector, seeking stocks of companies that we believe
offered a combination of growth potential and attractive prices.

An important term that has entered the vocabulary of the technology
marketplace is "bandwidth," and it is key to understanding future growth
trends. Bandwidth refers to the amount of data that can be sent through
a computer network; the higher the bandwidth, the higher the network
speed. With the explosive growth in Internet usage comes a huge demand
for more bandwidth.

Among the companies profiting from this demand are those that provide
the equipment to increase bandwidth, such as makers of fiber-optic
equipment. Fund holding Corning, Inc. is one example. The originator of
fiber-optic cable more than 20 years ago, Corning has capitalized on the
increased demand for faster, higher-capacity Internet connections, cable
modems, and high-speed phone lines. Corning's long-term growth potential
is evident in innovative products such as its LEAF fiber, which gives
networks the flexibility to handle increasing amounts of data and to
respond to growing bandwidth demands.


"In addition to selecting stocks with strong long-term growth potential,
we must carefully monitor portfolio holdings to determine the potential
tax consequences of our investment decisions."

-- Paul Marrkand, portfolio manager


Another standout in the fund's technology sector was the stock of
Juniper Networks. Juniper develops high-speed routers, which send
information across computer networks and are specifically designed to
accommodate the size and scope of the Internet. Juniper's leading
product, the M-40, is among the fastest Internet backbone routers
available. Juniper's stock was one of Wall Street's best success stories
of 1999, as the company rapidly gained market share in the extremely
competitive networking industry. While these holdings and 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.

* WIRELESS, MEDIA BENEFIT FROM GROWING DEMAND

While the number of cell-phone users continues to skyrocket around the
world, another new trend has begun to benefit wireless companies --
accessing the Internet through mobile phones. According to a new report
from IDC Research, 61.5 million people in the United States will be
using wireless devices to access the Internet by 2003, a 728% increase
over February 2000. Although wireless Internet service is in its
infancy, it has already boosted a number of stocks, including Motorola,
Inc., a holding that contributed positively to the fund's performance
during the period. Motorola produces wireless telephones and two-way
radio, messaging, and satellite communications products. While we
believe Motorola is a fundamentally strong company, we sold the fund's
position in April as part of our disciplined valuation process.

Footnote reads:
These holdings represent 27.3% of the fund's net assets as of 4/30/00.
Portfolio holdings will vary over time.


Another fund holding that has since been sold is QUALCOMM, Inc., a stock
that boosted performance during the semiannual period. The company
pioneered CDMA (code-division multiple access) technology, which has
become the high-quality standard for the next generation of cell phones
and wireless telecom equipment.

The media sector of the fund's portfolio also reaped the rewards of
Internet growth. Building brand recognition is vital to many Internet
companies and one of the most effective methods for doing this is to
advertise through traditional outlets such as TV, radio, and billboards.
This has boosted fund holdings such as AT&T-Liberty Media, which holds
equity positions in nearly 100 cable channels, including BET, Discovery
Channel, E!, Encore, QVC, and USA Networks. The company also has
numerous positions in overseas cable systems, many of which are in their
infancy and are expected to experience rapid growth.

* POSITIONED FOR VOLATILITY IN FISCAL YEAR'S SECOND HALF

As the period came to a close, our commitment to a disciplined
investment process became more significant as U.S. financial markets
continued to experience sharp volatility. We remain focused on
maximizing the portfolio's tax efficiency by investing with a long-term
perspective. This focus, combined with our intensive research and stock
selection process, should enable the fund to deliver solid long-term
returns over time.

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 4/30/00, there is no guarantee the fund will
continue to hold these securities in the future.


PERFORMANCE SUMMARY

should always be considered in light of its investment strategy. Putnam
Tax Smart Equity Fund, designed for investors seeking long-term growth
of capital on an after-tax basis, invests primarily in common stocks of
U.S. companies.

Past performance is no assurance of future results. More recent returns
may be more or less than those shown. Returns for class A and class M
shares reflect the current maximum initial sales charges of 5.75% and
3.50%, respectively. Class B share returns for the 1-, 5-, and 10-year
(where available) and life-of-fund periods reflect the applicable
contingent deferred sales charge (CDSC), which is 5% in the first year,
declines to 1% in the sixth year, and is eliminated thereafter. Returns
shown for class B and class M shares for periods prior to their
inception are derived from the historical performance of class A shares,
adjusted to reflect both the initial sales charge or CDSC, if any,
currently applicable to each class and in the case of class B and class
M shares the higher operating expenses applicable to such shares. For
class C shares, returns for periods prior to their inception are derived
from the historical performance of class A shares, adjusted to reflect
both the CDSC currently applicable to class C shares, which is 1% for
the first year and is eliminated thereafter, and the higher operating
expenses applicable to class C shares. All returns assume reinvestment
of distributions at NAV. Investment return and principal value will
fluctuate so that an investor's shares when redeemed may be worth more
or less than their original cost. For a portion of this period, the fund
was offered on a limited basis and had limited assets. Performance data
reflect an expense limitation currently or previously in effect. Without
the limitation, total returns would have been lower.

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.

Class A shares are generally subject to an initial sales charge.

Class B shares may be subject to a sales charge upon redemption.

Class C shares are not subject to an initial sales charge and are
subject to a contingent deferred sales charge only if the shares are
redeemed during the first year.

Class M shares have a lower initial sales charge and a higher 12b-1 fee
than class A shares and no sales charge on redemption.

Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including
any initial or contingent deferred sales charge.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 5.75% maximum sales charge for class A
shares and 3.50% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time
of the redemption of class B or C shares and assumes redemption at the
end of the period. Your fund's class B CDSC declines from a 5% maximum
during the first year to 1% during the sixth year. After the sixth year,
the CDSC no longer applies. The CDSC for class C shares is 1% for one
year after purchase.


COMPARATIVE BENCHMARKS

Standard & Poor's 500 Composite Stock Price Index is an index of common
stocks frequently used as a general measure of stock market performance.
The index assumes reinvestment of all distributions and interest
payments and does 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.

NOTES TO FINANCIAL STATEMENTS
April 30, 2000 (Unaudited)

Note 1
Significant accounting policies

Putnam Tax Smart Equity Fund (the "fund") is a series of Putnam Tax
Smart Funds Trust (the "trust") which is registered under the Investment
Company Act of 1940, as amended, as a diversified, open-end management
investment company. The fund seeks long-term growth of capital on an
after-tax basis by investing mainly in common stocks of mid and large
capitalization U.S. issuers, including both growth and value stocks,
that Putnam Investment Management, Inc. ("Putnam Management"), the
fund's manager, a wholly-owned subsidiary of Putnam Investments, Inc.
believes have potential for long-term growth.

The fund offers class A, class B, class C and class M shares. The fund
began offering class M shares on March 28, 2000. Class A shares are sold
with a maximum front-end sales charge of 5.75%. Class B shares, which
convert to class A shares after approximately eight years, do not pay a
front-end sales charge but pay a higher ongoing distribution fee than
class A shares, and are subject to a contingent deferred sales charge,
if those shares are redeemed within six years of purchase. Class C
shares are subject to the same fees and expenses as class B shares,
except that class C shares have a one-year 1.00% contingent deferred
sales charge and do not convert to class A shares. Class M shares are
sold with a maximum front end sales charge of 3.50% and pay an ongoing
distribution fee that is higher than class A shares but lower than class
B and class C shares.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class
(including the distribution fees applicable to such class). Each class
votes as a class only with respect to its own distribution plan or other
matters on which a class vote is required by law or determined by the
Trustees. Shares of each class would receive their pro-rata share of the
net assets of the fund, if that fund were liquidated. In addition, the
Trustees declare separate dividends on each class of shares.

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 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 Investments for which market quotations are
readily available are stated at market value, which is determined using
the last reported sales price on its principal exchange, or if no sales
are reported -- as in the case of some securities traded
over-the-counter -- the last reported bid price. Short-term investments
having remaining maturities of 60 days or less are stated at amortized
cost, which approximates market value. Other investments, including
restricted securities, are stated at fair value following procedures
approved by the Trustees.

B) Joint trading account Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the fund may transfer uninvested
cash balances into a joint trading account along with the cash of other
registered investment companies and certain other accounts managed by
Putnam Management. These balances may be invested in one or more
repurchase agreements and/or short-term money market instruments.

C) Repurchase agreements The fund, or any joint trading account, through
its custodian, receives delivery of the underlying securities, the
market value of which at the time of purchase is required to be in an
amount at least equal to the resale price, including accrued interest.
Collateral for certain tri-party repurchase agreements is held at the
counterparty's custodian in a segregated account for the benefit of the
fund and the counterparty. Putnam Management is responsible for
determining that the value of these underlying securities is, at all
times, at least equal to the resale price, including accrued interest.

D) 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. Dividend income is
recorded on the ex-dividend date except that certain dividends from
foreign securities are recorded as soon as the fund is informed of the
ex-dividend date.

E) Swap contracts The fund may engage in swap agreements, which are
agreements to exchange the return generated by one instrument for the
return generated by another instrument. The fund may enter into equity
swap agreements, to manage its exposure to equity markets, which involve
a commitment by one party to pay interest in exchange for a
market-linked return based on a notional amount. To the extent that the
total return of the security or index underlying the transaction exceeds
or falls short of the offsetting interest rate obligation, the fund will
receive a payment from or make a payment to the counterparty,
respectively. Equity swaps are marked to market daily based upon
quotations from market makers and the change, if any, is recorded as
unrealized gain or loss. Payments received or made at the end of the
measurement period are recorded as realized gains or losses. The fund
could be exposed to credit or market risk due to unfavorable changes in
the fluctuation of interest rates or in the price of the underlying
security or index, the possibility that there is no liquid market for
these agreements or that the counterparty may default on its obligation
to perform.

F) Line of credit The fund has entered into a committed line of credit
with certain banks. This line of credit agreement includes restrictions
that the fund maintain an asset coverage ratio of at least 300% and
borrowings must not exceed prospectus limitations. For the six months
ended April 30, 2000, the fund had no borrowings against the line of
credit.

G) Federal taxes It is the policy of the fund to distribute all of its
taxable 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 October 31, 1999, the fund had a capital loss carryover of
approximately $420,000 available to offset future net capital gains, if
any, which will expire on October 31, 2007.

H) 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.

I) Unamortized organization expenses Expenses incurred by the fund in
connection with its organization, its registration with the Securities
and Exchange Commission and with various states and the initial public
offering of its shares were $29,801. The offering costs of $22,801 have
been full amortized on a straight-line basis as of April 30, 2000.


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 following annual rates: 0.70% of the
first $500 million of average net assets, 0.60% of the next $500
million, 0.55% of the next $500 million, 0.50% of the next $5 billion,
0.475% of the next $5 billion, 0.455% of the next $5 billion, 0.44% of
the next $5 billion, and 0.43% thereafter.

Putnam Management has agreed to limit its compensation (and, to the
extent necessary, bear other expenses) through October 31, 2000, to the
extent that expenses of the fund (exclusive of brokerage commissions,
interest, taxes, deferred organizational and extraordinary expenses,
credits from Putnam Fiduciary Trust Company (PFTC), a subsidiary of
Putnam Investments, Inc., and payments under the Trust's distribution
plan) would exceed an annual rate of 1.25% of the fund's average net
assets.

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 PFTC. Investor
servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

For the six months ended April 30, 2000, fund expenses were reduced by
$12,937 under expense-offset arrangements with PFTC and brokerage
service arrangements. 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 $592
has been allocated to the fund, and an additional fee for each Trustee's
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.

The fund has adopted distribution plans (the "Plans") with respect to
its class A, class B, class C and class M shares pursuant to Rule 12b-1
under the Investment Company Act of 1940. The purpose of the Plans is to
compensate Putnam Mutual Funds Corp., a wholly-owned subsidiary of
Putnam Investments Inc., for services provided and expenses incurred by
it in distributing shares of the fund. The Plans provide for payments by
the fund to Putnam Mutual Funds Corp. at an annual rate up to 0.35%,
1.00%, 1.00% and 1.00% of the average net assets attributable to class
A, class B, class C and class M shares, respectively. The Trustees have
approved payment by the fund at an annual rate of 0.25%, 1.00%, 1.00%
and 0.75% of the average net assets attributable to class A, class B,
class C and class M shares, respectively.

For the six months ended April 30, 2000, Putnam Mutual Funds Corp.,
acting as underwriter received net commissions of $398,588 and $415 from
the sale of class A and class M shares, respectively, and received
$49,337 and $3,652 in contingent deferred sales charges from redemptions
of class B and class C shares, respectively. A deferred sales charge of
up to 1% is assessed on certain redemptions of class A shares. For the
six months ended April 30, 2000, Putnam Mutual Funds Corp., acting as
underwriter received no monies on class A redemptions.

Note 3
Purchases and sales of securities

During the six months ended April 30, 2000, cost of purchases and
proceeds from sales of investment securities other than short-term
investments aggregated $413,236,512 and $169,360,157, respectively.
There were no purchases and sales of U.S. government obligations.
