New York calendar and forms

New York keeps its dates on the federal calendar. The IT-201 is due April 15, 2027, the same day as the Form 1040; the four estimated payments fall on the federal dates; and the extension runs six months to October 15, 2027. The one thing New York does differently from many states, and from the way most people assume it works, is that the extension is not automatic unless you ask. A federal Form 4868 by itself does not extend the New York return; you must file Form IT-370 or request the extension online by April 15, and pay what you expect to owe at the same time. The other trap is the estimated-tax threshold, $300 rather than the federal $1,000, which catches retirees drawing IRAs with no state withholding.

The form side is shorter than it looks. Everyone files one return, the IT-201 for full-year residents or the IT-203 for part-year residents and nonresidents, and the New York City and Yonkers taxes are computed on it, so there is no separate city filing. Most filers add two or three schedules: IT-2 for W-2s, IT-225 for modifications such as the new tip subtraction, and IT-196 if itemizing for New York. The credit forms attach only when claimed. The New York State Department of Taxation and Finance publishes all of them, with fill-in versions, on its forms pages.

The 2027 filing season, dated

How the extension really works

New York grants an automatic six-month extension of time to file, but “automatic” means it will not be refused, not that it arrives without asking. The request must be made by April 15, online through the Department’s site (no account needed) or on paper Form IT-370. The Department’s page is blunt: “An extension request filed after the filing deadline for your return will be invalid.” It does not say a federal extension substitutes for a New York one, and practice says it does not (verify on the IT-370 instructions); file the New York request even if you have filed the federal one.

The extension does not extend the time to pay. The Department’s words: “If you apply for an extension and owe tax, you must make your extension payment by the due date.” Estimate the 2026 balance for New York State, New York City and Yonkers together and pay it with the request. Interest and the late-payment penalty run from April 15 on whatever was not paid by then. A return filed in October with the tax paid in April costs nothing extra; the same return with the tax paid in October costs interest and penalty on six months.

Estimated payments

New York requires estimated payments when you expect to owe $300 or more of New York State tax, $300 or more of New York City tax, or $300 or more of Yonkers tax after withholding and credits. That is less than a third of the federal $1,000 threshold, and it is why a retiree drawing an IRA with no state withholding can owe estimated payments to Albany while owing none to the IRS. The safe harbors match the federal ones: pay 90% of the 2026 tax or 100% of the 2025 tax in four timely installments and there is no penalty; the 100% rises to 110% if 2025 New York AGI was more than $150,000 ($75,000 married filing separately). Farmers and fishermen have their own rules. The penalty is figured on Form IT-2105.9. Payments go in with the IT-2105 voucher or through Online Services, which also shows every payment recorded against your estimated account. Pension payers are not required to withhold New York tax; a retiree who would rather not make quarterly payments can ask the payer to withhold on Form IT-2104-P.

The forms, in the order a filer meets them

Filing free, paying and checking a refund

Most paid preparers must e-file New York returns and may not charge extra for doing so, and the IT-201 instructions say a self-filer whose software supports e-file must e-file as well. The Department’s Free File page lists commercial software that files both the federal and New York returns at no cost for federal AGI of $89,000 or less; that is the 2025-return figure and the 2026 figure is to come. Check each provider’s own rules first, because a provider’s state eligibility can be narrower than its federal one. The Taxpayer Assistance Program prepares and e-files returns free, in person or virtually, at the same $89,000 limit with investment income of $11,950 or less. IRS Direct File, which took New York returns for 2024 and 2025, is not offered for the 2026 filing season.

Payments run through Online Services at tax.ny.gov, where a bank debit costs nothing; the extension payment and estimated payments can be made without an account, and an Individual Online Services account shows the estimated-tax account and lets you “view and respond to notices or bills.” Refund status is at the Department’s Check Your Refund tool or by phone at 518-457-5149, around the clock, using your Social Security number and the refund amount from IT-201 line 78 (verify 2026 line). The Department promises no timeline; it says e-filed returns with direct deposit are fastest, that claiming a credit you do not qualify for can add months, and that phone representatives see the same screen the tool does. Amended returns do not show in the tool.

Reaching the Department

The Department has no central fax number; documents answering a notice are uploaded through Online Services. Free interpretation is available, and the Office of the Taxpayer Rights Advocate handles cases the normal channels have not resolved.
