New Jersey state income tax calculator

Estimate New Jersey income tax using the 1.4%–10.75% bracket schedule.

How this calculator works

Step 1 starts with the New Jersey taxable income you already calculated on your return. If you are a part-year resident or nonresident, the tool applies the New Jersey income percentage you provide to focus on New Jersey-source income.

Step 2 applies New Jersey's graduated schedule (1.4% through 10.75%) to estimate total tax.

Step 3 summarizes the effective and marginal rates so you can see how additional income would be taxed and whether your current estimate matches your expectations.

Frequently asked questions

What income should I enter?

Use New Jersey taxable income from your return. If you only know total income, estimate deductions first or use the standard deduction tool.

Do part-year residents prorate income?

Yes. Use the New Jersey income allocation percentage from your return to prorate taxable income before applying the New Jersey bracket schedule.

Does New Jersey have different brackets by filing status?

Yes. Joint and head-of-household filers have wider middle brackets (for example, $20k–$50k and $50k–$70k), while single/MFS filers have $20k–$35k and $35k–$40k tiers.
