What makes New York different

  • New York layers additional forms on the IT-205 — IT-205-A for nonresident and part-year situations — and its 5½-month extension deliberately mirrors the federal Form 7004 window, so both returns extend to the same September date.
  • New York has an e-file mandate: if your software can e-file the IT-205, you are generally required to e-file it rather than mail it.

The federal return comes first

Form IT-205 does not replace the federal filing — an estate or trust that meets the federal thresholds ($600 of gross income, any taxable income for a trust, or a nonresident alien beneficiary) files the federal Form 1041 with the IRS and then the New York return with the Tax Department, which generally starts from the federal figures. The practical workflow: finish the federal 1041 and its Schedule K-1s, then carry the numbers into Form IT-205. Our federal Form 1041 guide covers the thresholds, deadlines, and elections, and the Schedule K-1 guide explains what beneficiaries do with their share.

New York fiduciary tax FAQs

Who must file New York Form IT-205?
A resident estate or trust that must file a federal 1041, had any New York taxable income, or is subject to the lump-sum distribution tax; a nonresident estate or trust with New York-source income, a New York NOL, or lump-sum distribution tax.
When is Form IT-205 due?
The 15th day of the 4th month after the year ends — April 15 for calendar-year filers. Extension: 5½ months, matching the federal window — file Form IT-370-PF (or pay any tax due by the deadline and the extension applies automatically). September 30 for calendar-year filers.
What is the New York fiduciary tax rate?
New York's graduated rates, up to 10.9% at the highest bracket. Rates and thresholds change — verify against the current Form IT-205 instructions from New York State Department of Taxation and Finance before computing.
Do I still file the federal Form 1041 if I file Form IT-205?
Yes — they are separate obligations. The federal Form 1041 goes to the IRS under the federal $600 gross-income (or any-taxable-income) thresholds, and Form IT-205 goes to the Tax Department under New York's own rules. Most fiduciaries prepare the federal return first, since the state return typically starts from federal amounts.
Does New York accept the federal Form 7004 extension for the IT-205?
No — New York requires its own extension. File Form IT-370-PF (or make the required payment electronically) by the original due date for the automatic 5½-month state extension. A federal 7004 alone does not extend the New York return.
