Printer-Friendly Version (PDF)

General information

Purpose

To get an automatic extension of time to file Form IT-201, Resident Income Tax Return, or IT-203, Nonresident and Part-Year Resident Income Tax Return, file Form IT-370 on or before the due date of the return. 

If you live in the United States, we cannot grant an extension of time to file for more than six months. However, if you are outside the United States and Puerto Rico, or you intend to claim nonresident status—under Tax Law § 605(b)(1)(A)(ii) (548-day rule)—you may qualify for an extension of time to file beyond six months.

See § 157.3(b)(1) of the personal income tax regulations and the instructions for Form IT-203 under Additional information.

Also see the Special condition codes instructions for the return you will be filing (Form IT-201 or Form IT-203).

Notes:

• Do not submit a copy of the federal extension form. We will not accept it in place of Form IT-370 and your due date will not be extended.
• If you are required to file Form Y-203, Yonkers Nonresident Earnings Tax Return, we will automatically extend the time to file when you file Form IT-370. For more information on who is required to file Form Y-203, see the instructions for the form.
• If you are requesting an extension of time to file using Form IT-370, you may still electronically file Form IT-201 or Form IT-203 any time before the extension period ends, provided you meet the conditions for electronic filing as listed in the instructions for the forms.

Filing deadlines

On or before the filing deadline for the return, complete and file Form IT-370. 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 the fifteenth day of the fourth month following the close of your tax year (April 15, 2025, for calendar-year filers).

Exceptions

 If you qualify for one of the following, see Special condition codes, below.

 If you are out of the country, you qualify for an automatic two-month extension of time to file your federal and New York State income tax returns, and you need an additional four months to file:

• File Form IT-370 by June 16, 2025.
• File your income tax return on or before October 15, 2025.

 If you are a U.S. nonresident noncitizen for federal income tax purposes, and you qualify to file your federal and New York State income tax returns on June 16, 2025, and you need an additional six months to file:

• File Form IT-370 by June 16, 2025.
• File your income tax return by December 15, 2025.

 If you qualify for a 90-day extension of time to file because your spouse died within 30 days before your return due date and you need additional time to file:

• If your due date is April 15, 2025:
  • File Form IT-370 by July 14, 2025.
  • File your income tax return on or before October 15, 2025.

• If you are a nonresident noncitizen and your due date is June 16, 2025:
  • File Form IT-370 by September 15, 2025.
  • File your income tax return on or before December 15, 2025.

If you qualify for an extension of time to file beyond six months, you must file Form IT-370 on or before the filing deadline for your return.

How to file

On or before the due date of your return, complete Form IT-370 and file it, along with your payment for any tax you owe. To determine if a payment is required, use the Worksheet below.

Payment of tax – To obtain an extension of time to file, you must make full payment of the properly estimated tax balances due. For payment options, see Make a payment when you have an extension of time or visit www.tax.ny.gov (search: pay).

Penalties

Late payment penalty

If you do not pay your tax liability when due (determined with regard to any extension of time to pay), you 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 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, and metropolitan commuter transportation mobility tax (MCTMT) 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-201 or Form IT-203 when due (determined with regard to any extension of time to file), or if you do not file Form IT-370 on time and obtain an extension of time to file, you will have to pay a penalty of 5% of the 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 your 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 tax due on the return minus any 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, MCTMT, or sales or use tax 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.

Specific instructions

Filling in your form

When you complete Form IT-370, use black ink (and never use red ink).

Married taxpayers

If you:

• file separate returns, you must complete separate Forms IT-370. Do not include your spouse’s Social Security number (SSN) or name on your separate Form IT-370.
• file a joint Form IT-370, the payment you make with that form will be divided equally between the spouses’ accounts. Both of your accounts will be applied to your joint return when you file it.
• file a Form IT-203-C, Nonresident or Part-Year Resident Spouse’s Certification, do not list the spouse with no New York source income on Form IT-370.

If you do list that spouse, the payment you make with Form IT-370 will be divided between the two accounts. However, when you file your return and attach Form IT-203-C, we will not apply the payment in the account of the spouse with no New York source income, without prior authorization.
