Form IT-270: New York City Income Tax Elimination Credit (Tax Year 2025)

Form IT-270 is a New York State tax form used to claim the New York City Income Tax Elimination Credit. It’s issued by the New York State Department of Taxation and Finance and is meant for a fairly narrow group of taxpayers: people who lived in New York City for only part of the year and whose income situation qualifies them for this specific credit. If you moved into or out of the five boroughs during the tax year, this form is likely one of the pieces you need to get your state return right.

The credit itself exists to offset city income tax liability for part-year NYC residents whose New York adjusted gross income falls below a certain threshold. Because New York City income tax is calculated separately from state income tax, part-year residents can end up owing city tax even during months when they weren’t fully established as city residents. The elimination credit is designed to reduce that burden for filers who meet the income limits set by the state.

Who Needs to File Form IT-270

You’ll generally need this form if all of the following apply to your situation for tax year 2025:

• You were a New York City resident for only part of the year (not the full 12 months).
• You filed or are filing a New York State resident or part-year resident income tax return.
• Your income falls within the limits established for the NYC Income Tax Elimination Credit.

Full-year New York City residents don’t use this form — it’s specifically for part-year residents. Similarly, if you never lived in NYC during the tax year, this credit doesn’t apply to you. The form is attached to your main New York State return; it isn’t filed on its own.

When You’d Use It

Form IT-270 gets used during the same filing season as your regular New York State income tax return — so for tax year 2025, that means filing in early 2026 alongside Form IT-201 or IT-203, depending on your residency status. There’s no separate deadline for IT-270; it follows the standard New York State income tax filing deadline. If you request an extension on your state return, the credit claim on IT-270 gets pushed back along with it.

It’s worth noting that this credit is relatively small in scope compared to broader state or federal credits, but skipping it when you qualify means leaving money that’s rightfully yours unclaimed. If you’ve relocated to or from NYC mid-year, it’s worth double-checking your eligibility rather than assuming the credit doesn’t apply.

How to Get and Complete the Form

Form IT-270 is available as a fillable PDF directly from the New York State Department of Taxation and Finance website. The current version has AcroForm fields, meaning you can type your information directly into the PDF using standard software like Adobe Acrobat Reader before printing or attaching it to your electronic filing.

To fill it out, you’ll need your New York adjusted gross income figures, the dates you lived in New York City during the tax year, and basic identifying information matching your main state return. The form walks through a short calculation to determine your credit amount based on income thresholds published by the state for the applicable tax year. Once completed, it’s submitted along with your New York State income tax return — not mailed separately.

If you’re also dealing with other state-specific credits or nonresident tax situations, it helps to compare how different states structure similar relief. For example, taxpayers navigating multi-state or specialty credits sometimes find it useful to review how New York handles nonresident obligations elsewhere, such as in Form IT-2664 for nonresident cooperative unit estimated tax payments. Filers who split time between states, rather than boroughs, may also want to look at how other states structure their own credit programs, like California’s Competes Tax Credit under Form 3531 or the prior-year AMT credit claimed on Form 3510, for a sense of how differently states approach similar tax relief mechanisms.

Keep a copy of your completed IT-270 with your tax records. If the Department of Taxation and Finance has questions about your part-year residency dates or income calculation, having your worksheet and supporting documents on hand will make responding to any follow-up requests much easier.
