New Jersey levies a graduated state income tax with rates climbing from 1.4% to a top 10.75% millionaire’s rate. This calculator applies the official 2024 brackets for single and married-filing-jointly filers, subtracts New Jersey’s personal and dependent exemptions, and shows your tax, effective rate, and marginal bracket.
How it works
New Jersey income tax is computed in three steps:
- Subtract exemptions. New Jersey gives a
$1,000personal exemption per filer (plus$1,000for a spouse on a joint return) and$1,500per dependent. Subtract these from gross income to get taxable income. - Apply the graduated brackets. Each portion of taxable income is taxed at its bracket rate — the first dollars at
1.4%, higher portions at progressively higher rates up to10.75%. The brackets are wider for married-filing-jointly filers. - Sum the bracket amounts. Adding the tax from every bracket gives your total New Jersey tax. The effective rate is total tax divided by gross income.
Tips and example
For a single filer earning $80,000 with no dependents: subtract the $1,000 personal exemption to get $79,000 taxable. New Jersey taxes this across several brackets, producing roughly $2,500 in state tax — an effective rate near 3.1%.
New Jersey does not tax Social Security and offers a large retirement income exclusion, so retirees often pay far less than the brackets alone suggest. This tool covers wage and ordinary income; use the New Jersey retirement income tool for pension and Social Security treatment.
