Dear Shareholder:

Putnam New York Tax Exempt Money Market Fund's recently concluded fiscal
year coincided with one of the more volatile market environments in
recent memory.  As is typically the case under such conditions, demand
for money market securities increased substantially throughout the year.
In the process of investing the fund's swelling assets, your fund's
manager, Brian Torpey, was able to take advantage of the fact that
money-market yields have risen -- reflecting the higher short-term
interest rates implemented by the Federal Reserve Board this year.  The
following report provides further details of his strategies and shows
how the fund benefited as a result.

Shortly after the end of the fund's fiscal year, Brian took on other
responsibilities within our Tax Exempt Bond Group.  We are pleased to
announce that Joyce E. Dragone has been appointed as your fund's
manager.  Before assuming her new position, Joyce was a municipal bond
trader in the Tax Exempt Bond Group.  Her association with Putnam dates
back to 1981. She has 18 years of investment experience.

Respectfully yours,

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

REPORT FROM FUND MANAGEMENT

Brian S. Torpey

Money market investments attracted great interest during much of the 12
months ended November 30, 2000. Uncertainty about the direction of
interest rates, the stock market's volatility, and the outcome of the
U.S. presidential election late in the year convinced investors to seek
the relative safety and predictability of short-term investments.
Tax-exempt money market funds enjoyed an additional benefit: the
strength of the U.S. economy has been generating greater personal
wealth, which investors are eager to shelter from taxes.

Not surprisingly, money market assets have climbed dramatically. As of
November 30, 2000, Lipper Analytical Services reported that U.S. money
market assets grew 15.60% from a year earlier -- a considerable
increase. With this growth has come some constraints, however, as
municipal money market issuance in New York has not kept pace with
demand. We have focused our efforts on seeking to maintain Putnam New
York Tax Exempt Money Market Fund's competitive yield, stable share
value, and strategic diversification in the midst of very dynamic and
overwhelmingly positive market conditions.

* SOUND STATE ECONOMY, POLITICAL LEADERSHIP GENERATED HISTORIC BUDGET SURPLUS

Like much of the nation, the Empire State is enjoying strong economic
growth, which has led to sizable budget surpluses. In fact, New York
City just recorded 20 consecutive years of operating surpluses, despite
a heavy debt burden. The size of its surplus for fiscal 2000 was larger
than any time in its recorded history. Most certainly, Wall Street's
continued profitability is a large factor in this happy state of
affairs.

At the state level, Governor Pataki and the legislature approved the
Debt Reform Act of 2000 after broad bipartisan efforts. The passage of
this bill, which places restrictions on the state's ability to issue new
debt, boosts New York's political credibility because it preserves the
status quo debt burden level and minimizes the risk of any increase in
the state's debt. Given these positive developments, both New York City
and New York state bonds received favorable reviews from the rating
agencies. Moody's and Standard & Poor's recently upgraded New York City
bond ratings from A3 and A- to A2 and A, respectively. Moody's also
changed its outlook for New York state from stable to positive -- a step
that typically presages a credit upgrade. These credit developments have
had a very positive impact on the prices of bonds held in your
portfolio.

* SHORT-TERM INTEREST RATES ROSE BUT SUPPLY/DEMAND IMBALANCE PRESSURED YIELDS

The Federal Reserve Board may have assumed a more neutral stance in the
final weeks of 2000, but its anti-inflationary bias pushed short-term
interest rates higher during much of your fund's fiscal year. The
federal funds rate (the rate of interest associated with borrowing among
the member banks of the Federal Reserve System) rose from 5.25% to 6.50%
during the 12 months ended November 30, 2000. The yields on new tax-free
money market securities coming to market have also risen, resulting in
incremental boosts to the fund's yield.

On the other hand, our efforts have been complicated by the fact that
investor demand far exceeds the supply of new municipal money market
issues. With rising tax revenues, the state and its municipalities have
less need to borrow to finance their operations. Yet, considering New
York's high taxes and high per capita income, state and local municipal
obligations remain one of the most attractive ways for investors to
shelter their income from taxes. Consequently, strong, steady demand in
the face of light supply is pushing yields of New York short-term
municipal bonds below the national average. (When demand is high, bond
prices rise and bond yields fall.)

* PORTFOLIO REFLECTS COMMITMENT TO PRINCIPAL STABILITY

With new investment opportunities limited, the fund ended its fiscal
year with 61% of its assets invested in variable rate demand notes
(VRDNs). VRDNs are brought to market with a 30-year maturity and a
coupon that resets at par, or face value, daily, weekly, or monthly,
depending on the structure of the municipal debt. Since the bonds reset
at par, they lend stability to the fund's net asset value and help
preserve principal. These bonds also contain a put option, which allows
the bondholder (Putnam) to tender the bonds for purchase on the date a
new interest rate is set -- thereby establishing their short-term
status. To meet such a demand, we require the issuer to have some form
of liquidity or credit support. This can take the form of a letter of
credit from a major commercial bank or a standby purchase agreement from
an insurance company.

The fund's remaining assets were split among other short-term
investments, tax-exempt notes (27%) and tax-exempt commercial paper
(8%). Tax-exempt notes provide interim financing for state and local
governments when there is a shortfall between expenses and the
collection of tax revenues. To qualify as short-term municipal
securities, these notes must mature within 13 months or 397 days from
the date of purchase. Credit quality of the issuing municipality and
yield are important factors to weigh when assessing the value of such
notes. Tax-exempt commercial paper is another conduit through which
municipalities can issue short-term debt. The fund's commercial paper
investments typically have maturities of 60 to 90 days, although
maturities can run between 30 and 120 days.

On November 30, the fund's average days to maturity was 31 days. This
maturity was shorter than the current norm but is a function of the
demand/supply dynamics shaping the current municipal bond market.
Typically, the fund's average days to maturity falls in the range of 50
to 60 days and cannot exceed 90 days.

* MORE FAVORABLE INTEREST RATE SCENARIO ANTICIPATED

The Fed did not raise interest rates in October or November, shifted to
a neutral bias in December, and in a surprise move on January 3rd, cut
short-term rates by 50 basis points. While we've always said that
monetary policy changes works with a lag of six to twelve months, this
interest rate cut should give the economy a much-needed psychological
boost.

In this environment, your fund's management team will continue to
monitor the supply of new issuance in the hope of adding longer-term
securities to extend the fund's average days to maturity. While credit
quality remains paramount, tax-exempt notes offer an attractive way to
augment the fund's income stream in the current interest rate
environment. However, the addition of longer-term securities would
become an option once yields on New York short-term municipal debt move
more into line with yields on comparable securities around the nation.
In the meantime, are confident that the current mix of investments
offers a healthy balance of stability and tax-free income for our
shareholders.

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. An investment in
the fund is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. Although the fund seeks to
preserve your investment at $1.00 per share, it is possible to lose
money by investing in the fund.

The net asset value of money market mutual funds is uninsured and
designed to be fixed, while distributions vary daily. Investment returns
will fluctuate. The principal values on passbook savings and on bank CDs
are generally insured up to certain limits by state and federal
agencies. Unlike stocks, which incur more risk, CDs offer a fixed rate
of return. Unlike money market funds, bank CDs may be subject to
substantial penalties for early withdrawals.

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, not including
any initial or contingent deferred sales charge.


COMPARATIVE BENCHMARKS

Lipper New York Tax Exempt Money Market Fund Average, used for
performance comparison purposes, is an arithmetic average of the total
return of all New York tax exempt money market mutual funds tracked by
Lipper Analytical Services. Lipper is an independent rating organization
for the mutual fund industry. Lipper rankings vary for other periods.
The fund's holdings do not match those in the Lipper average. 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, preceded by the Report of independent
accountants, 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.



REPORT OF INDEPENDENT ACCOUNTANTS

The Board of Trustees and Shareholders
Putnam New York Tax Exempt Money Market Fund

We have audited the accompanying statement of assets and liabilities of
Putnam New York Tax Exempt Money Market Fund,  including the fund's
portfolio, as of November 30, 2000, and the related statement of
operations for the year then ended, statement of changes in net assets
for the year then ended and financial  highlights for the year then
ended. These financial  statements and financial highlights are the
responsibility of the Fund's  management. Our  responsibility is to
express an opinion on these financial statements and financial
highlights based on our audit. The statement of changes in net assets
for the year ended November 30, 1999, and the  financial highlights for
each of the years in the four-year period ended November 30, 1999 were
audited by other auditors whose report dated January 7, 2000 expressed
an unqualified opinion on that financial statement and those  financial
highlights.

We conducted our audit in accordance with auditing standards generally
accepted in the United States of America. Those standards require that
we plan and perform our audit to obtain reasonable assurance about
whether the financial statements and financial highlights are free of
material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as
of November 30, 2000 by correspondence with the custodian and brokers.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audit
provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of Putnam New York Tax Exempt Money Market Fund as of
November 30, 2000, the results of its operations, changes in its net
assets and financial highlights for the year then ended, in conformity
with accounting  principles generally accepted in the United States of
America.

  (a) Percentages indicated are based on net assets of $39,277,657.

(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. Ratings are not covered by
      the Report of independent accountants.

      Moody's Investor Service, Inc. and Standard & Poor's Corp. are the leading
      independent rating agencies for debt securities. Moody's uses the designation
      "Moody's Investment Grade", or "MIG", for most short-term adding a "V" ("VMIG")
      for bonds with a demand or variable feature; the designation "P" is used for
      tax exempt commercial paper. Standard & Poor's uses "SP" for notes maturing in
      three years or less, "A" for bonds with a demand or variable feature

      Moody's Investor Service, Inc.

      MIGI/VMIGI = Best quality; strong protection of cash flows, superior liquidity
      and broad access to refinancing
      MIG2/VMIG2 = High quality; ample protection of cash flows, liquidity support
      and ability to refinance
      Aaa = Extremely strong capacity to pay interest and repay principal
      Aa = Strong capacity to pay interest and repay principal and differs from the
      higher rated issues only in a small degree

      P-1 = Superior capacity for repayment `
      P-2 = Strong capacity for repayment

      Standard & Poor's Corp.
      AAA = Extremely strong capacity to pay interest and repay principal
      AA = Strong capacity to pay interest and repay principal and differs
      from the higher rated issues only in a small degree
      SP-1+ = Very strong capacity to pay principal and interest
      SP-1 = Strong capacity to pay principal and interest
      SP-2 = Satisfactory capacity to pay principal and interest
      A-1+ = Extremely strong degree of safety
      A-1 = Strong degree of safety
      A-2 = Satisfactory capacity for timely repayment

  (b) The aggregate identified cost on a tax basis is the same.

(PRE) These securities are prerefunded with callable dates within a year.

      The rates shown on VRDN's are the current interest rates shown at
      November 30, 2000 which are subject to change based on the terms of the
      security.

      The fund had the following industry group concentrations greater than 10% at

NOTES TO FINANCIAL STATEMENTS
November 30, 2000

Note 1
Significant accounting policies

Putnam New York Tax Exempt Money Market Fund (the "fund") is registered
under the Investment Company Act of 1940, as amended, as a
nondiversified, open-end management investment company. The fund seeks
as high a level of current income exempt from federal, New York State
and New York City personal income taxes as Putnam Investment Management,
LLC ("Putnam Management"), the fund's manager, a wholly owned subsidiary
of Putnam Investments, Inc., believes is consistent with the maintenance
of liquidity, preservation of capital and stability of principal. The
fund invests primarily in a nondiversified portfolio of short-term New
York tax exempt securities.

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 in 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 The valuation of the funds' portfolio instruments
is determined by means of the amortized cost method (which approximates
market value) as set forth in Rule 2a-7 under the Investment Company Act
of 1940. The amortized cost of an instrument is determined by valuing
it at its original cost and thereafter amortizing any discount or
premium from its face value at a constant rate until maturity.

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.

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.

D) Interest income and distributions to shareholders Interest is
recorded on the accrual basis. Income dividends are recorded daily by
the fund and are paid monthly to the shareholders.

E) Amortization of bond premium and accretion of bond discount Premiums
and discounts from purchases of short-term investments are
amortized/accreted at a constant rate until maturity.

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: 0.45% of the
first $500 million of average net assets, 0.35% of the next $500
million, 0.30% of the next $500 million, 0.25% of the next $5 billion,
0.225% of the next $5 billion, 0.205% of the next $5 billion, 0.19% of
the next $5 billion, and 0.18% thereafter.

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.

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 year ended November 30, 2000,
the fund's expenses were reduced by $60,087 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $279 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.

For the year ended November 30, 2000, Putnam Retail Management, Inc., a
wholly-owned subsidiary of Putnam Investments, Inc., acting as
underwriter receives proceeds from contingent deferred sales charges
that apply to certain shares that have been exchanged from other Putnam
funds. Putnam Retail Management, Inc., received no monies in contingent
deferred sales charges from such redemptions.

Note 3
Purchases and sales of securities

During the year ended November 30, 2000, cost of purchases and proceeds
from sales (including maturities) of investment securities (all
short-term obligations) aggregated $106,547,777 and $108,012,175,
respectively.

Note 4
Capital shares

At November 30, 2000, there was an unlimited number of shares of
beneficial interest authorized. Transactions in capital shares at a
constant net asset value of $1.00 per share were as follows:

                                                     Year ended November 30

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

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 fund's independent accountants and voted to appoint KPMG LLP
for the fund's fiscal year ended November 30, 2000. 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.

Note 6
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.


FEDERAL TAX INFORMATION
(Unaudited)

The fund has designated 100% of dividends paid from net investment
income during the fiscal year as tax exempt for Federal income tax
purposes.

The Form 1099 you receive in January 2001 will show the tax status of
all distributions paid to your account in calendar 2000.
