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.
