How this calculator works

Step 1 calculates your capital gain using cost basis and sale proceeds. If you provide dates, the tool classifies the holding period for reference.

Step 2 adds the gain to your other New Jersey taxable income and applies the graduated brackets. Holding period is tracked for context only.

Step 3 shows the New Jersey tax impact. The marginal rate reflects the bracket your total income lands in after the gain.

Frequently asked questions

Does New Jersey have a special long-term gain rate?

New Jersey taxes capital gains as ordinary income. Some qualified gains or extraordinary dividends may qualify for a state deduction, which is not applied here.

What if I have a loss?

Losses are displayed for context. Check New Jersey’s rules for how losses offset gains.

Do I need to adjust for residency?

Part-year and nonresident filers should prorate New Jersey-source income using the allocation percent on their return.
