File Your Tax Return Now →New York Personal Income Tax Extension – Federal Extension Not Accepted
New York State does not honor IRS Form 4868. New York residents who need more time to file must submit Form IT-370 (Application for Automatic Six-Month Extension of Time to File for Individuals) directly with the New York State Department of Taxation and Finance by April 15, 2026. This moves the state filing deadline to October 15, 2026. Full payment is still due April 15.
Form IT-370 Must Be Filed by April 15
New York does not accept your federal Form 4868 as a state extension. You must file Form IT-370 separately – online at tax.ny.gov or by mail – by April 15, 2026. Missing this deadline means your New York return is simply late.
Pay Your Full New York Liability with the Extension
New York’s extension covers only filing – not payment. Pay 100% of your New York income tax liability by April 15, 2026, to avoid both filing and payment penalties running simultaneously on any unpaid balance.
Filing Form IT-370
Form IT-370 can be filed online at tax.ny.gov – the fastest option – or submitted by mail with payment. Filing online generates an immediate confirmation number; save it as proof of timely filing.
Making Extension Payments
New York accepts online extension payments at tax.ny.gov by clicking “Make a payment” under Individuals. Both ACH debit and credit card are available – American Express, Discover, MasterCard, and Visa accepted with a convenience fee on card payments. Save the confirmation number from any online payment.
Late Filing and Payment Penalties
New York’s failure-to-file penalty is 5% of unpaid tax per month, up to 25%. The failure-to-pay penalty is 0.5% per month, also capped at 25%. Not filing Form IT-370 by April 15 triggers both penalties simultaneously on any unpaid balance – making timely filing of IT-370 critical even when you can’t pay in full.
Best Practices
- ✓Do not rely on IRS Form 4868 – New York requires its own Form IT-370 filed by April 15.
- ✓File IT-370 online at tax.ny.gov and save your confirmation number.
- ✓Pay your full New York tax liability by April 15, 2026, to avoid penalties and interest.
- ✓File your completed New York return by October 15, 2026.
New York’s extension process demands its own separate action – the federal extension won’t save you here. File Form IT-370 and pay in full by April 15, then file your return by October 15, 2026.
