File electronically

Electronic preparation (e-file) is fast, easy, and secure. You may even qualify for free filing options. For all your e-file options, see Filing Season Resource Center.

For the fastest processing of your refund, combine e-file with direct deposit. You can receive your New York State tax refund up to two weeks sooner than if you filed by paper and requested a paper check.

User-friendly e-file software ensures you file all the right forms and do not miss out on valuable credits.

E-file information

Using software?

You must e-file if your software allows you to e-file your return, or if you are a tax preparer who is subject to the e-file mandate. E-file is easy, safe, and allows you to get your refund faster. Most New York taxpayers e-file.

Make a payment

Pay a balance due by authorizing the Tax Department to withdraw the payment from your bank account. Authorize the payment when you e-file your return or make a return payment after you file your return using our Online Services. You may also pay with a credit card.

For more information, visit our website at www.tax.ny.gov (search: pay).

    How are you taxed as a nonresident or as a part-year resident?

    If you were a nonresident of New York State, you are subject to New York State tax on income derived from New York State sources.

    If you were a resident of New York State for only part of the tax year, you must pay New York State tax on all income you received while you were a resident of the state and on income you received from New York State sources while you were a nonresident.

    To determine how much tax you owe, use Form IT-203, Nonresident and Part‑Year Resident Income Tax Return. You will compute a base tax as if you were a full-year resident, then determine the percentage of your income that is subject to New York State tax and the amount of tax apportioned to New York State.
