reinvestment of distributions and does not account for taxes.

Performance commentary

Municipal bond yields, particularly those of intermediate-maturity
bonds, generally declined during the six-month period ended October 31,
2004. This created a positive environment for bond prices, which rose as
yields fell. Our emphasis on uninsured bonds with higher yields in an
environment that favored higher-yielding securities helped the fund's
performance exceed that of its benchmark, the Lehman Municipal Bond
Index. The fund performed in line with the average for its Lipper peer
group, based on results at net asset value. Results at market price
outperformed the average; however, it is important to note that a fund's
performance at market price may differ from its results at NAV. Although
market price performance generally reflects investment results, it may
also be influenced by several other factors, including changes in
investor perceptions of the fund or its investment advisor, market
conditions, fluctuations in supply and demand for the fund's shares, and
changes in fund distributions.

FUND PROFILE

Putnam New York Investment Grade Municipal Trust seeks to provide high
current income free from federal income tax and New York state and city
personal income taxes, consistent with the preservation of capital. It
may be suitable for New York investors seeking tax-free income through a
diversified portfolio of high-quality bonds.


Market overview

Over the past six months, which constitute the first half of your fund's
2005 fiscal year, the yield on the 10-year Treasury bond fell, and bond
prices, which move in the opposite direction of yields, rose. In
mid-March, the bond market had begun to anticipate a change in the
Federal Reserve Board's monetary policy. Treasury bonds sold off sharply
and pushed yields upward, as strong economic growth and rising corporate
profitability increased the likelihood that the Fed would raise
short-term interest rates at its June 30 meeting. Interestingly, when
the Fed announced what had been a widely anticipated 25-basis-point
increase, the bond market changed its course. Yields of bonds with
maturities in the range of 11-21 years trended downward. At the same
time, yields rose for bonds with short maturities and those with very
long maturities (over 21 years). This resulted in a flattening of the
yield curve -- that is, shorter- and longer-term interest rates began to
converge.

Among uninsured bonds and bonds rated A and below, yield spreads
remained essentially flat for the period. However, these higher-yielding
securities continued to provide attractive income streams that
contributed to the fund's total return during the period. Among the
strongest performing bonds in the overall municipal bond market were
those issued by the state of California. The California economy improved
to such an extent that three bond-rating agencies -- Moody's, Standard &
Poor's, and Fitch -- upgraded the state's credit rating. Tobacco
settlement bonds performed fairly well during the period. Yields on
these bonds varied with the results of ongoing legal battles, but
declined overall since May, and their prices rose, accordingly.
Airline-related industrial development bonds (IDBs) performed poorly, in
general, as the industry continued to face financial difficulties that
were made worse by record high oil prices. New York City general
obligation bonds rose in price over the past six months, reflecting a
dearth of new issuance, as well as investors' confidence in improving
economic prospects for the city.

Strategy overview

Because we believe that the Fed is likely to continue to raise short-term
interest rates through mid-2005, we are positioning the portfolio more
defensively. This involves shortening the fund's duration, which means
reducing its sensitivity to changes in interest rates. To accomplish this, we
began the process of selling longer-term bonds and replacing them with
shorter-term bonds, which have a shorter duration. Meanwhile, we continued to
trim and diversify the fund's positions in uninsured bonds and bonds rated A
and below, which have performed strongly. The fund maintained its overweight
position in tobacco settlement bonds relative to its benchmark. We closely
monitored developments in that sector. The fund had less exposure to
airline-related IDBs during the period than did its peers. The fund also
continues to employ less leverage than its peers, making it slightly more
conservative in this regard. This strategy generally detracts from relative
performance versus the fund's peer group when fixed-income markets are
rallying, as they did during the past six months, but helps to protect fund
performance when markets are falling.

In previous fiscal years, the fund emphasized non-callable bonds -- bonds that
the issuer is not permitted to redeem (or call) before the maturity date.
These issues performed well as rates fell through March 2004, but during the
spring we began to moderate this position, selling non-callable bonds and
purchasing callable issues scheduled to mature in the 15- to 20-year range. We
believe callable bonds may perform better than non-callable bonds if interest
rates rise and the yield curve flattens further.

Average effective maturity also takes into account put and call
features, where applicable, and reflects prepayments for mortgage-backed
securities.


How fund holdings affected performance

Higher-yielding bonds have performed well over the past two years, fueled by
demand from income-oriented investors in an environment of historically low
yields. The fund's strategy of emphasizing uninsured bonds with higher yields,
though still within the investment-grade spectrum, helped relative performance
during the six-month period. Examples of fund holdings in this category that
were strong contributors to results include A3-rated bonds issued by the
Dutchess County Industrial Development Agency for Bard College, Baa-rated
bonds issued by Niagara County Development Agency for American Ref-Fuel
Company, and bonds issued by the Long Island Power Authority, which are rated
Baa1. (All ratings are by Moody's.)

New York City General Obligation bonds (GOs) were another solid
contributor to fund results during the period. These bonds performed
well due to their low supply amid continued strong demand, as well as
improving investor perceptions of the city's financial health.

Generally, fund holdings with maturities in the 2015 to 2025 range made
the greatest contribution to results during the period, as rates fell
most among these intermediate maturities. Particularly strong
performance in this category came from insured bonds issued by the
Metropolitan Transportation Authority that are scheduled to mature in
2020.

As a percentage of market value as of 10/31/04. A bond rated Baa or
higher is considered investment grade. The chart reflects Moody's
ratings; percentages may include bonds not rated by Moody's but
considered by Putnam Management to be of comparable quality. Ratings
will vary over time.

The fund's greater-than-benchmark weighting in New York tobacco settlement
bonds was another positive during the period as this segment of the market
performed well. Payments from these high-yielding issues are secured by income
promised to states through legal settlements from tobacco companies. This
income could be jeopardized as a result of multibilliondollar judgments
against the tobacco companies, and prices in this sector have shifted as
concerns about litigation overshadowed optimism. Our analyst believes that,
despite several highly visible lawsuits against the tobacco industry,
litigation risk is receding from where it was in 1999. Also, cigarette
consumption levels appear to be holding steady.  However, a tobacco settlement
bond issued by the Puerto Rico Children's Trust Fund Tobacco Settlement
underperformed in the period due to unfavorable market technical factors
rather than to the bond's underlying fundamentals. Considering the risks, we
have diversified the fund's investments in these bonds and remain watchful of
the situation.

Please note that all holdings discussed in this report are subject to
review in accordance with the fund's investment strategy and may vary in
the future.


The outlook for your fund

The following commentary reflects anticipated developments that could
affect your fund over the next six months, as well as your management
team's plans for responding to them.

Judging from the flattened yield curve, the bond market appears to have
largely shrugged off the recent Fed rate hikes. However, we believe that
interest rates all along the yield curve are more likely to rise than
fall. After the close of the fiscal period, the Fed again raised the
discount rate by 25 basis points, or one quarter of a percentage point.
Going forward, we anticipate greater increases for bonds with shorter
maturities because we believe the Fed will continue to raise short-term
rates incrementally through mid-2005. This also suggests further
flattening of the yield curve. The fund is positioned defensively in
terms of duration, and we will continue to monitor and adjust the fund's
duration as seems appropriate. We believe inflation will remain low,
despite the threat posed by high oil prices. We also anticipate that the
rate of GDP growth will slow during the next two quarters, as the
effects of the Fed's tightening policy are felt.

In general, these signs indicate that we are headed into a more
challenging environment for bond investing. Our task will be to continue
to search for the most attractive opportunities among tax-exempt
securities, and to balance the pursuit of attractive current income with
prudent risk management.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. This fund
concentrates its investments in one state and involves more risk than a
fund that invests more broadly. Capital gains, if any, are taxable for
federal and, in most cases, state purposes. For some investors,
investment income may be subject to the federal alternative minimum tax.
Income from federally exempt funds may be subject to state and local
taxes. Mutual funds that invest in bonds are subject to certain risks,
including interest-rate risk, credit risk, and inflation risk. As
interest rates rise, the prices of bonds fall. Long-term bonds are more
exposed to interest-rate risk than short-term bonds. Unlike bonds, bond
funds have ongoing fees and expenses.

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 the fund.
Market prices are set by transactions between buyers and sellers on
exchanges such as the American Stock Exchange and the New York Stock
Exchange.

A note about duplicate mailings

In response to investors' requests, the SEC has modified mailing
regulations for proxy statements, semiannual and annual reports, and
prospectuses. Putnam is now able to send a single copy of these
materials to customers who share the same address. This change will
automatically apply to all shareholders except those who notify us. If
you would prefer to receive your own copy, please call Putnam at
1-800-225-1581.

Proxy voting

Putnam is committed to managing our mutual funds in the best interests
of our shareholders. The Putnam funds' proxy voting guidelines and
procedures, as well as information regarding how your fund voted proxies
relating to portfolio securities during the 12-month period ended June
30, 2004, are available on the Putnam Individual Investor Web site,
www.putnaminvestments.com/individual, and on the SEC's Web site,
www.sec.gov. If you have questions about finding forms on the SEC's Web
site, you may call the SEC at 1-800-SEC-0330. You may also obtain the
Putnam funds' proxy voting guidelines and procedures at no charge by
calling Putnam's Shareholder Services at 1-800-225-1581.

Fund portfolio holdings

For periods ending on or after July 9, 2004, the fund will file a
complete schedule of its portfolio holdings with the SEC for the first
and third quarters of each fiscal year on Form N-Q. Shareholders may
obtain the fund's Forms N-Q on the SEC's Web site at www.sec.gov. In
addition, the fund's Forms N-Q may be reviewed and copied at the SEC's
public reference room in Washington, D.C. You may call the SEC at
1-800-SEC-0330 for information about the SEC's Web site or the operation
of the public reference room.


A guide to the financial statements

These sections of the report, as well as the accompanying Notes,
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.
This is done by first adding up all the fund's earnings -- from
dividends and interest income -- and subtracting its operating expenses
to determine net investment income (or loss). Then, any net gain or loss
the fund realized on the sales of its holdings -- as well as any
unrealized gains or losses over the period -- is added to or subtracted
from the net investment result to determine the fund's net gain or loss
for the fiscal period.

Statement of changes in net assets shows how the fund's net assets were
affected by the fund's net investment gain or loss, 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
October 31, 2004 (Unaudited)

Note 1
Significant accounting policies

Putnam New York Investment Grade Municipal Trust (the "fund"), a
Massachusetts business trust, is registered under the Investment Company
Act of 1940, as amended, as a non-diversified, closed-end management
investment company. The fund's investment objective is to seek a high
current income exempt from federal income tax and New York State and
City personal income tax. The fund intends to achieve its objective by
investing in investment grade municipal securities constituting a
portfolio that Putnam Investment Management, LLC ("Putnam Management"),
the fund's Manager, an indirect wholly-owned subsidiary of Putnam, LLC,
believes to be consistent with preservation of capital. The fund may be
affected by economic and political developments in the state of New
York.

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 Tax-exempt bonds and notes are valued at fair
value on the basis of valuations provided by an independent pricing
service, approved by the Trustees. Such services use information with
respect to transactions in bonds, quotations from bond dealers, market
transactions in comparable securities and various relationships between
securities in determining value. Other investments are valued 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 recorded 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. All premiums/discounts
are amortized/accreted on a yield-to-maturity basis. The premium in
excess of the call price, if any, is amortized to the call date;
thereafter, any remaining premium is amortized to maturity.

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 of 1986 (the "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 Code, 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 April 30, 2004, the fund had a capital loss carryover of $2,452,701
available to the extent allowed by the Code to offset future net capital
gain, if any. The amount of the carryover and the expiration dates are:

Loss Carryover      Expiration
----------------------------------
      $491,807      April 30, 2005
       433,833      April 30, 2008
       311,892      April 30, 2011
     1,215,169      April 30, 2012

Pursuant to federal income tax regulations applicable to regulated
investment companies, the fund has elected to defer to its fiscal year
ending April 30, 2005 $42,859 of losses recognized during the period
November 1, 2003 to April 30, 2004.

The aggregate identified cost on a tax basis is $45,458,687, resulting
in gross unrealized appreciation and depreciation of $2,097,084 and
$248,979, respectively, or net unrealized appreciation of $1,848,105.

D) Distributions to shareholders Distributions to common and preferred
shareholders from net investment income are recorded by the fund on the
ex-dividend date. Distributions from capital gains, if any, are recorded
on the ex-dividend date and paid at least annually. 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 28 day period. The applicable dividend rate for the
remarketed preferred shares on October 31, 2004 was 1.45%. 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.

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, less all
liabilities and the liquidation preference of any outstanding remarketed
preferred shares, by the total number of common shares outstanding as of
period end.

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 0.65% of the fund's weekly average net
assets attributable to common and preferred shares outstanding.

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 gross income attributable to
the proceeds of the remarketed preferred shares during that period, then
the fee payable to Putnam Management for that period will be reduced by
the amount of the excess (but not more than 0.65% of the liquidation
preference of the remarketed preferred shares outstanding during the
period).

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, LLC. Putnam
Investor Services, a division of PFTC, provides investor servicing agent
functions to the fund. During the six months ended October 31, 2004, the
fund paid PFTC $22,076 for these services.

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 October 31,
2004 the fund's expenses were reduced by $9,904 under these
arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $473, as a quarterly retainer, 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
Trustee compensation and expenses in the statement of operations. Accrued
pension liability is included in Payable for Trustee compensation and expenses
in the statement of assets and liabilities. The Trustees have terminated the
Pension Plan with respect to any Trustee first elected after 2003.

Note 3
Purchases and sales of securities

During the six months ended October 31, 2004 cost of purchases and
proceeds from sales of investment securities other than short-term
investments aggregated $13,709,789 and $14,534,747 respectively. There
were no purchases or sales of U.S. government securities.

Note 4
Preferred shares

The Series A shares are redeemable at the option of the fund on any
dividend payment date at a redemption price of $50,000 per share, plus
an amount equal to any dividends accumulated on a daily basis but unpaid
through the redemption date (whether or not such dividends have been
declared) and, in certain circumstances, a call premium.

It is anticipated that dividends paid to holders of remarketed preferred
shares will be considered tax-exempt dividends under the Internal
Revenue Code of 1986. To the extent that the fund earns taxable income
and capital gains by the conclusion of a fiscal year, it may 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
October 31, 2004, no such restrictions have been placed on the fund.

Note 5
Regulatory matters and litigation

On April 8, 2004, Putnam Management entered into agreements with the
Securities and Exchange Commission ("SEC") and the Massachusetts
Securities Division representing a final settlement of all charges
brought against Putnam Management by those agencies on October 28, 2003
in connection with excessive short-term trading by Putnam employees and,
in the case of the charges brought by the Massachusetts Securities
Division, by participants in some Putnam-administered 401(k) plans. The
settlement with the SEC requires Putnam Management to pay $5 million in
disgorgement plus a civil monetary penalty of $50 million, and the
settlement with the Massachusetts Securities Division requires Putnam
Management to pay $5 million in restitution and an administrative fine
of $50 million. The settlements also leave intact the process
established under an earlier partial settlement with the SEC under which
Putnam Management agreed to pay the amount of restitution determined by
an independent consultant, which may exceed the disgorgement and
restitution amounts specified above, pursuant to a plan to be developed
by the independent consultant.

Putnam Management, and not the investors in any Putnam fund, will bear
all costs, including restitution, civil penalties and associated legal
fees stemming from both of these proceedings. The SEC's and
Massachusetts Securities Division's allegations and related matters also
serve as the general basis for numerous lawsuits, including purported
class action lawsuits filed against Putnam Management and certain
related parties, including certain Putnam funds. Putnam Management has
agreed to bear any costs incurred by Putnam funds in connection with
these lawsuits. Based on currently available information, Putnam
Management believes that the likelihood that the pending private
lawsuits and purported class action lawsuits will have a material
adverse financial impact on the fund is remote, and the pending actions
are not likely to materially affect its ability to provide investment
management services to its clients, including the Putnam funds.
