New York City resident tax
People who live in any of the five boroughs pay NYC personal income tax on the same taxable income as the state, at four graduated rates from 3.078% to 3.876%. It is a residence tax: commuting into Manhattan from New Jersey, Long Island or Westchester does not trigger it, and moving out of the city ends it.
Yonkers
Yonkers residents pay a surcharge of 16.75% of their net state tax rather than a percentage of income. Nonresidents who work in Yonkers pay a separate earnings tax that the calculator does not model.
Disability and Paid Family Leave
New York employers must provide disability benefits insurance and Paid Family Leave, and may recover part of the cost from employees. The Workers’ Compensation Board fact sheet sets the DBL employee share at no more than 0.5% of wages and 60 cents a week. The calculator assumes your employer takes the maximum employee share of both; if your paystub shows less, your employer is covering more.
Credits left out
The Empire State child credit, New York and NYC earned income credits, household credits and the NYC school tax credit can reduce tax or produce refunds for many families. They depend on details beyond wages and are listed as not covered.
