New Jersey Capital Gains Tax Rules
New Jersey has no separate capital gains rate. Short-term and long-term gains are both taxed as ordinary income at New Jersey's 2026 rates from 1.4% to 10.75%; the top rate applies above $1,000,000 of taxable income. This state tax is separate from — and in addition to — the federal capital gains tax you owe to the IRS.
Understanding New Jersey's capital gains rules is essential for investors, homeowners selling property, and business owners who plan to sell assets. The calculator above computes your estimated federal and New Jersey state capital gains tax based on your sale price, cost basis, holding period, and income. It subtracts the 2026 federal standard deduction ($16,100 single, $32,200 married filing jointly, $24,150 head of household) from the income you enter, stacks the gain on top of your other income, and taxes each slice at its own rate.
Federal vs New Jersey Capital Gains Tax
The federal tax on a gain depends on your taxable income and on how long you held the asset. For long-term gains (held more than 12 months), the 2026 federal rates set by IRS Rev. Proc. 2025-32 are 0% on taxable income up to $49,450 single / $98,900 married filing jointly / $66,200 head of household, 15% up to $545,500 single / $613,700 joint / $579,600 head of household, and 20% above those thresholds. The gain is stacked on top of your other income, so one sale can be taxed partly at 0%, partly at 15% and partly at 20%. Short-term gains are taxed as ordinary income at the 2026 federal brackets of 10% to 37%. A 3.8% Net Investment Income Tax is added on the lesser of the gain or the amount by which your modified adjusted gross income exceeds $200,000 (single or head of household) or $250,000 (married filing jointly).
Worked example (2026): a single filer with $90,000 of other income sells stock held for two years at a $50,000 gain. Federal tax is $7,500 (the whole gain falls in the 15% band) and New Jersey tax is $3,185, a combined $10,685 or 21.4% of the gain. Sold after 11 months instead, the same gain is short-term: $11,364 federal plus $3,185 New Jersey tax, $14,549 in total. The calculator above reproduces both results.
New Jersey Cap Gains Strategies & Exemptions
Several strategies can help New Jersey taxpayers reduce their capital gains tax burden. First, hold assets for more than 12 months to qualify for the lower long-term federal rate. Second, harvest capital losses to offset gains — if you have losing positions, selling them in the same tax year can reduce your net taxable gain. Third, use tax-advantaged accounts (401k, IRA, HSA) to shelter future investment growth from both federal and New Jersey state tax.
For New Jersey homeowners, the federal home-sale exclusion allows you to exclude up to $250,000 (single) or $500,000 (married filing jointly) of gain from the sale of a primary residence, provided you meet the 2-of-5-year ownership and use tests. The calculator does not apply this exclusion, so enter only the gain that remains after it. Consult a New Jersey tax professional to understand which exclusions apply to your specific situation.
Always work with a qualified tax professional before executing large asset sales. Tax laws change, and individual circumstances — such as installment sales, like-kind exchanges (1031 exchanges for real estate), or business asset sales — can significantly affect your total tax liability.

New Jersey has no separate capital gains rate. In 2026 a gain is taxed as ordinary income at rates from 1.4% to 10.75% (the top rate applies above $1,000,000 of taxable income), so the state tax depends on your total income.
Does New Jersey tax short-term vs long-term capital gains differently?
No. New Jersey taxes short-term and long-term capital gains the same way, as ordinary income.
