New Jersey Capital Gains Tax 2026
Estimate the state tax attributable to a gain, then separate it from the federal capital-gains calculation.
State-specific rule
New Jersey does not follow every federal capital-gain exclusion or loss rule, so the state taxable gain can differ from the federal figure.

Frequently asked questions
Does New Jersey have a lower rate for long-term capital gains?
New Jersey includes taxable net gains from property dispositions in gross income and applies its progressive individual rates.
Does this include federal capital gains tax?
No. This page estimates the state layer. Use the federal capital gains calculator for the 0%, 15% or 20% long-term rate, ordinary short-term rates and possible 3.8% NIIT.
Why does other income change the result?
The gain can stack on top of other taxable income. In a progressive system, some or all of the gain may therefore fall into higher state brackets.
