How the New Jersey income tax calculator works
Enter your gross income. The calculator applies federal tax brackets plus New Jersey's own state brackets — a flat rate, or none at all, in the states that work that way — to find your income tax, then subtracts Social Security and Medicare to estimate your net take-home pay, shown as an annual total and a per-paycheck breakdown.
How New Jersey taxes compare
New Jersey layers 7 state brackets on top of the federal ones, topping out at 10.8% on income above $1,000,000, and subtracts a — standard deduction first. By top state rate alone, New Jersey ranks 4 of the 51 US jurisdictions covered here — though the bracket *thresholds* matter as much as the headline rate, since a high top rate that only bites at a high income costs a median earner little.
The math: federal plus state brackets
Income tax is calculated using marginal tax brackets — each portion of income is taxed at its own bracket's rate, not the top rate applied to the whole amount. Federal tax and New Jersey's state tax are calculated separately using their own bracket tables, then added together. FICA — 6.2% Social Security up to the annual wage base, plus 1.45% Medicare on every dollar — is calculated on top of income tax to find your take-home pay.
Worked example
On $75,000 of employment income in New Jersey, this calculator estimates $10,321 of combined federal and state income tax — an average rate of 13.8% and a marginal rate of 28.4% — leaving $58,941 before FICA comes off. Change the salary above and every figure recalculates against New Jersey's own 2026 brackets.

- Mandatory withholdings beyond income tax: FICA — 6.2% Social Security up to the annual wage base, and 1.45% Medicare on all wages.
