New York Tax Refund

Option 1: If you don't owe New York income taxes and don't expect a refund by the deadline, you don't need to file a New York tax extension. However, if you expect a refund, you must file or e-file your New York tax return to receive it.

Option 2: If you've e-filed for a federal extension and don't owe New York income taxes or expect a refund, your accepted federal extension automatically extends your New York state tax deadline, so you don't need to file Form IT-370.

Owe New York Taxes

Option 1: Pay your New York income taxes online using the official New York State Department of Taxation and Finance website: New York Tax Online Service.

Option 2: If you owe New York income taxes, you must file a New York tax return or an extension by the deadline to avoid late filing penalties. You can e-file an IRS extension. However, the extension will give you until October to file, but you must pay all your taxes or file your return by October deadline to avoid further penalties.

Option 3: Fill out Form IT-370 and mail it to the address provided, along with a check or money order. Remember, you must still file your New York tax return by the October deadline, whether you filed an extension or not. You can e-file or file on paper.

Tax Penalties
Important: You may be subject to IRS and NY late filing penalties if you owe income taxes to both New York and the IRS and you fail to file an IRS and New York tax return or an extension by the Tax Due Date. Compute the IRS late filing and penalty amounts. Furthermore, you will incur late tax payment penalties if you fail to pay your taxes by the deadline. Only the late filing penalties—not the late tax payment penalties—will be waived by timely filing an extension. In general, late filing penalties are more severe than late payment penalties, so even if you are unable to make a timely payment, make sure to file on time!
