New York tax forms & filing.

Things to know about filing in New York

• New York City residents pay a separate New York City income tax on top of the New York State tax. The city tax is administered through the state return but is a distinct calculation — and Yonkers has yet another separate city tax.
• New York's 'convenience of the employer' rule sources telecommuting wages to New York if the employer is New York-based and the employee is working from another state for personal convenience rather than employer requirement. This catches many remote workers based in NJ, CT, FL, or PA who work for NY-based companies.
• New York's resident definition uses both a domicile test and a statutory residency test (183 days + permanent place of abode in New York). Both tests can independently establish residency. New York audits residency claims aggressively — particularly for high-income filers who claim a move out of state.
• New York has its own estate tax with a threshold below the federal threshold. Estates above the New York threshold but below the federal threshold still owe New York estate tax, with a 'cliff' provision that can wipe out the credit entirely for estates slightly above the threshold.
• New York taxes capital gains at the regular bracket rate, not a preferential rate. This matters more than federally because the top New York rate is high.

The New York 'convenience of the employer' rule — explained

New York's convenience-of-the-employer rule is one of the most aggressive non-resident-income provisions in the country. Here's how it works: if you're a non-resident working remotely for a New York-based employer, your wages are sourced to New York for state-tax purposes unless your work is performed outside New York out of necessity, not convenience.

In practice: a software engineer who lives in Connecticut and works from a Connecticut home office for a New York employer — by choice, not requirement — pays New York state income tax on those wages. A nurse who lives in Pennsylvania but must work at a New York hospital location pays New York tax on the hospital-day wages but Pennsylvania tax on the Pennsylvania-day wages. The distinction is whether the out-of-state work is required by the job or chosen by the employee.

The Connecticut credit-for-taxes-paid provision usually neutralizes the double-taxation for CT-resident NY workers. New Jersey, Pennsylvania, and Florida residents working for NY employers may face less clean offsetting. We model this at intake when a client's W-2 shows New York wages but the address is out of state.

NYC and Yonkers — separate from the state

New York City and Yonkers each levy their own income tax on top of the state tax. Both are calculated on Form IT-201 schedules and flow through the state return — but they're distinct calculations driven by city residency and city work-location rules.

If you live in NYC or Yonkers, you pay the city tax on all your income (similar to the state). If you work in NYC or Yonkers but live outside, the city tax applies only to certain work-location-sourced income, depending on the city and the year. Yonkers also assesses an Earnings Tax on non-resident workers performing services in Yonkers.

Most-misfiled scenario: a recent NYC-to-Hoboken move where the client still works in Manhattan. The first post-move return shows NYC residency for the part-year period and non-resident treatment afterward. The interaction with the New Jersey resident return (and the NJ credit for NY taxes paid) is where mistakes happen.

Multi-state filing patterns we see most often for New York residents

NJ-resident, NYC employer: File NY non-resident (IT-203), pay NY state + NYC nonresident earnings tax if applicable, claim NJ credit on NJ-1040 for NY tax paid. This is the single most common multi-state filing pattern for the NYC metro.

CT-resident, NYC employer: Similar pattern with Connecticut credit-for-tax-paid logic. Convenience-of-the-employer rule pushes the source to NY for remote-work days, which CT credits cover when consistent.

FL-resident, NYC employer: Florida has no state income tax to offset NY tax. The full NY non-resident tax bill is borne entirely without state-level offset — this is the most expensive pattern and worth modeling pre-move.

Where's my refund?

The New York State Department of Taxation and Finance runs the official refund-status tracker. You'll need your Social Security number, filing status, and exact refund amount (in some cases, the tax year and a return-amount input).

Multi-state considerations

If you lived or worked in more than one state during the tax year, you typically file a part-year resident return in each state. If you live in one state and work in another, you usually file as a resident where you live and as a nonresident in the work state — claiming a credit on the resident return for taxes paid to the work state. Reciprocity agreements between some neighboring states change this default; we map this out at intake.

New York-specific multi-state nuances are addressed in the quirks list above when they apply.
