Printer-Friendly Version (PDF)

General information

Purpose

To get an automatic extension of time to file Form IT-204, Partnership Return, or IT-205, Fiduciary Income Tax Return, file Form IT-370-PF on or before the due date of the return.

Form IT-370-PF automatically extends the due date for filing as follows:

• Form IT-204: six months
• Form IT-205: five and one-half months 

Form IT-370-PF does not extend the time for filing New York State income tax returns of partners of a partnership or the beneficiaries of an estate or trust. To apply for an extension of time to file those returns, use Form IT-370, Application for Automatic Six-Month Extension of Time to File for Individuals. 

Notes:

• Do not submit a copy of the federal extension form. We will not accept it in place of Form IT-370-PF and your due date will not be extended.
• If you are required to file Form Y-206, Yonkers Nonresident Fiduciary Earnings Tax Return, we will automatically extend the time to file when you file Form IT-370-PF. For more information on who is required to file Form Y-206, see the instructions for the form. 
• You may file Form IT-204 or Form IT-205 any time before the extension period ends.

Filing deadlines

On or before the filing deadline for the return, complete and file Form IT-370-PF. If you file your extension application after the filing deadline for the return:

• the application will not be accepted, and
• we will not extend your due date.

 Generally, the filing deadline is:

• Partnerships: the fifteenth day of the third month following the close of your tax year (for calendar-year filers, March 17, 2025).
• Estates and trusts: the fifteenth day of the fourth month following the close of your tax year (for calendar-year filers, April 15, 2025).
• Nonresident noncitizen estates or trusts: on or before June 16, 2025, if you qualify to file your federal and New York State income tax returns on June 16, 2025. See the Special condition codes below.

How to file

 You must complete a separate Form IT-370-PF to request an extension of time to file for each:

• partnership (including limited liability companies [LLCs], limited liability investment companies [LLICs], and limited liability trust companies [LLTCs] treated as partnerships),
• limited liability partnership, and
• estate or trust.

Form IT-205 filers: You must file Form IT-370-PF with payment for any tax owed on or before the due date of the return (see Worksheet below).

Penalties

Partnerships

A partnership will be charged a penalty if it is required to file Form IT-204 and:

• it fails to file that return on time, including any extension of time; or
• it files a return that is incomplete and fails to show the information required under Tax Law section 658(c).

The penalty will be imposed for each month or part of a month, up to a maximum of 5 months, that the above failure continues. The penalty for each month is calculated by multiplying $50 by the total number of partners in the partnership during any part of the partnership’s tax year who were also subject to New York personal income tax during any part of the tax year. 

If you show reasonable cause for filing late, we will not charge the penalty.

Estates and trusts

Late payment penalty

If an estate or trust does not pay its income tax liability when due (determined with regard to any valid extension of time to pay), it will have to pay a penalty of ½ of 1% of the unpaid amount for each month or part of a month it is not paid, up to a maximum of 25%. This penalty is in addition to the interest charged for late payments.

 If you show reasonable cause for paying late, we will not charge the penalty.

Reasonable cause will be presumed with respect to the addition to tax for late payment of income tax if:

• you complied with the requirements relating to extensions of time to file;
• the balance due shown on your income tax return, minus any sales or use tax you owe, does not exceed 10% of the total New York State, New York City, and Yonkers tax shown on the income tax return; and
• you paid the balance due shown on the income tax return when you filed your return.

Late filing penalty

If you do not file Form IT-205 when due (determined with regard to any extension of time to file), or if you do not file Form IT-370-PF on time and obtain an extension of time to file, you will have to pay a penalty of 5% of the income tax due for each month, or part of a month, the return is late up to a maximum of 25%.

However, if you do not file the return within 60 days of the filing deadline (including extensions), this penalty will be at least the lesser of the following amounts, either:

• $100, or
• 100% of the amount required to be shown as income tax due on the return, minus any income tax you paid and any credit you may be eligible to claim.

 If you show reasonable cause for filing late, we will not charge the penalty.

Interest

If you do not pay the income tax or sales or use tax that you owe on or before the due date of your return, you will be charged interest on any amount due, even if you received an extension of time to file your return. Interest is a charge for the use of money and in most cases may not be waived. Interest is compounded daily and the rate is adjusted quarterly.

For more information about how interest is calculated, see Interest and penalties or visit www.tax.ny.gov (search: interest).

Fee for payments returned by banks

The law allows the Tax Department to charge a $50 fee when a check, money order, or electronic payment is returned by a bank for nonpayment. However, if an electronic payment is returned as a result of an error by the bank or the department, the department will not charge the fee.

 If your payment is returned, we will send you a separate bill for $50 for each return or other tax document associated with the returned payment.
