How a New York paycheck works
An employee in New York sees federal deductions, state deductions and, for city residents, a city income tax. The federal part is income tax withheld according to Form W-4 plus Social Security and Medicare. The state part is New York State income tax withheld under the exact calculation method of the Department of Taxation and Finance, together with two small employee contributions: the disability benefits deduction and the Paid Family Leave contribution. Residents of the five boroughs also have New York City income tax withheld, from the city’s own tables. The employer pays its Social Security and Medicare shares and federal unemployment tax on top, plus state unemployment insurance and other employer-only levies at rates that depend on the employer.
Federal income tax withholding
The employer takes the annual wage, subtracts the standard deduction for the filing status chosen in Step 1 of Form W-4, applies the progressive rate schedule for that status, and reduces the result by any dependent credits entered in Step 3. The calculator reproduces that annual computation for a W-4 with nothing in Steps 2 and 4: one job, no spouse income, no other income, no extra withholding. Single and married filing separately share one schedule.
The child tax credit in Step 3 applies in full below the statutory income limit. Above it the credit shrinks by a fixed amount for every thousand dollars of excess, and the calculator applies that reduction so the estimate does not jump at the limit.
Social Security and Medicare
Social Security is withheld at a flat rate up to the annual wage base; Medicare has none. Once wages in the year pass a fixed threshold the employer also withholds the Additional Medicare tax on the excess regardless of filing status. The employer matches the Social Security and regular Medicare contributions but not the additional tax.
New York State income tax and the IT-2104
New York withholding follows the exact calculation method in publication NYS-50-T-NYS. The employer subtracts a deduction allowance that depends on whether the employee is single or married, subtracts a fixed amount for each withholding allowance claimed on Form IT-2104, and applies the annual rate schedule to the remainder. The schedule is not a plain set of brackets: its middle rows carry the recapture that gradually removes the benefit of the lower rates from higher earners, which is why the effective rate keeps climbing well into six-figure salaries. For very high wages the tables hand over to the top income tax rates method, where one rate applies to the whole amount.
New York has only two withholding statuses. A head of household is withheld as single; the head-of-household option on this page still changes the federal computation.
New York City income tax
People who live in New York City pay a city income tax on the same wages, withheld by the employer from the city tables when the employee indicates city residence on the IT-2104. Working in the city without living there does not trigger it. Yonkers has its own resident and non-resident surcharges, which this calculator does not include.
Disability benefits and Paid Family Leave
New York requires employers to provide short-term disability coverage and Paid Family Leave. Employees may be asked to contribute to both: a small percentage of wages capped at a fixed weekly amount for disability benefits, and a percentage of wages up to an annual cap, set each year from the statewide average weekly wage, for Paid Family Leave. Both appear as separate lines here.
What this calculator assumes
The result models a regular employee paid evenly through the year, with a standard Form W-4 and IT-2104, no pre-tax deductions and no Yonkers tax. It does not cover:
- Pre-tax contributions to a 401(k), health premiums or commuter benefits, which reduce taxable wages.
- Extra withholding requested on either form, or the W-4 adjustments in Steps 2 and 4.
- Bonuses and other supplemental wages, which are withheld at flat supplemental rates.
- Yonkers resident and non-resident taxes, and the metropolitan commuter transportation mobility tax, which employers pay.
- Employer-side state unemployment insurance and re-employment fund contributions.
Withholding versus your final tax bill
Withholding is a prepayment. On the federal, state and city returns the standard computation is replaced by your actual situation: itemized deductions if larger, other income, and credits such as the New York City school tax credit. Most single-job employees receive a refund; people with two jobs, a working spouse or investment income often owe. Use this page to plan a monthly budget and a full return estimate to plan the year.
