New accounting pronouncement

In June 2006, the Financial Accounting Standards Board
(FASB) issued Interpretation No. 48, Accounting for
Uncertainty in Income Taxes (the Interpretation).  The
Interpretation prescribes a minimum threshold for
financial statement recognition of the benefit of a
tax position taken or expected to be taken by a filer
in the filers tax return.  The Interpretation will
become effective for fiscal years beginning after
December 15, 2006 but will also apply to tax positions
reflected in the funds financial statements as of that
date.  No determination has been made whether the
adoption of the Interpretation will require the fund
to make any adjustments to its net assets or have any
other effect on the funds financial statements.
The effects of implementing this pronouncement, if any,
will be noted in the funds next semiannual financial
statements.

In September 2006, the FASB issued Statement of
Financial Accounting Standards No. 157, Fair Value
Measurements (the Standard).  The Standard defines
fair value, sets out a framework for measuring fair
value and requires additional disclosures about fair
value measurements.  The Standard applies to fair
value measurements already required or permitted by
existing standards.  The Standard is effective for
financial statements issued for fiscal years beginning
after November 15, 2007 and interim periods within those
fiscal years.  Putnam Management is currently
evaluating what impact the adoption of the Standard
will have on the funds financial statements.

Report of Independent Registered Public Accounting Firm


To the Trustees and Shareholders of Putnam New York Investment
Grade Municipal Trust:

In planning and performing our audit of the financial
statements of Putnam New York Investment Grade Municipal Trust
(the Fund) as of and for the year ended April 30, 2007, in
accordance with the standards of the Public Company Accounting
Oversight Board (United States), we considered the Funds
internal control over financial reporting, including control
activities for safeguarding securities, as a basis for
designing our auditing procedures for the purpose of expressing
our opinion on the financial statements and to comply with the
requirements of Form NSAR, but not for the purpose of
expressing an opinion on the effectiveness of the Funds
internal control over financial reporting.  Accordingly, we do
not express an opinion on the effectiveness of the Funds
internal control over financial reporting.

The management of the Fund is responsible for establishing and
maintaining effective internal control over financial
reporting.  In fulfilling this responsibility, estimates and
judgments by management are required to assess the expected
benefits and related costs of controls.  A funds internal
control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted
accounting principles.  Such internal control over financial
reporting includes policies and procedures that provide
reasonable assurance regarding prevention or timely detection
of unauthorized acquisition, use or disposition of a funds
assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

A control deficiency exists when the design or operation of a
control does not allow management or employees, in the normal
course of performing their assigned functions, to prevent or
detect misstatements on a timely basis.  A significant
deficiency is a control deficiency, or combination of control
deficiencies, that adversely affects the funds ability to
initiate, authorize, record, process or report external
financial data reliably in accordance with generally accepted
accounting principles such that there is more than a remote
likelihood that a misstatement of the funds annual or interim
financial statements that is more than inconsequential will not
be prevented or detected.  A material weakness is a control
deficiency, or combination of control deficiencies, that
results in more than a remote likelihood that a material
misstatement of the annual or interim financial statements will
not be prevented or detected.

Our consideration of the Funds internal control over financial
reporting was for the limited purpose described in the first
paragraph and would not necessarily disclose all deficiencies
in internal control over financial reporting that might be
significant deficiencies or material weaknesses under standards
established by the Public Company Accounting Oversight Board
(United States).  However, we noted no deficiencies in the
Funds internal control over financial reporting and its
operation, including controls for safeguarding securities,that
we consider to be material weaknesses as defined above as of
April 30, 2007.

This report is intended solely for the information and use of
management and the Board of Trustees of Putnam New York
Investment Grade Municipal Trust and the Securities and
Exchange Commission and is not intended to be and should not be
used by anyone other than these specified parties.
