New Jersey bonus tax questions

What is the New Jersey bonus tax rate for 2026?

New Jersey has no flat bonus tax rate: a bonus paid separately is withheld through the state's graduated rate tables as if it were a whole paycheck, with no allowances. On a $10,000 bonus that is $611 of New Jersey tax.

Is a bonus taxed more than regular pay in New Jersey?

No. When you file, a bonus is taxed at the same New Jersey rates as the rest of your wages; only the withholding differs. For a single filer with $75,000 of wages, a $10,000 bonus adds $629 to the year's New Jersey tax and has $611 withheld, so $18 less is withheld than owed. The rest is due when you file.

Why can New Jersey withhold too much from a large bonus?

A bonus paid at a different time from regular wages is run through New Jersey's rate table for your pay period on its own, as one paycheck, with none of your NJ-W4 allowances. The table's brackets are sized for one paycheck, so a large bonus reaches its top rates even when your yearly income does not: if you are paid every two weeks, a $50,000 bonus has $4,522 withheld against $3,177 of added tax, $1,346 too much. Your pay period matters too: a $10,000 bonus has $507 withheld if you are paid monthly and $611 if you are paid every two weeks. A bonus paid with regular wages is withheld on the combined payment.

What the calculator leaves out

  • NJ-WT names no pay period for a bonus paid separately, so the calculator runs the whole bonus through the rate table for your regular pay period, every two weeks unless you choose another.
  • A bonus paid at a different time from regular wages is withheld on its own as one pay period's wages, with none of the allowances on your NJ-W4.
  • Single filers and married people filing separately are withheld at Rate A; joint filers and heads of household at Rate B, unless line 3 of the NJ-W4 selects another rate table.
  • A bonus paid with regular wages is withheld on the combined payment.

Supplemental wage withholding rules (NJ-WT): latest published, 2025. September 2025 edition, whose rate tables apply to wages paid on and after October 1, 2020; no 2026 edition published.

Federal income tax is withheld at the 22% supplemental rate, 37% on supplemental pay above $1,000,000 in a year. Social Security and Medicare treat the bonus as the year's last pay, so wages above $184,500 owe no more Social Security. Filing status changes only the annual comparison.
