Capital Gains Calculators
New Jersey Capital Gains Tax Calculator
NJ taxes all gains as ordinary income up to 10.75% — and if you've already moved out of state, the "exit tax" is really just a withholding prepayment, not a separate tax.
NJ capital gains tax
Ordinary income rates, no long-term discount.
NJ "Exit Tax" withholding estimator
Only applies if you're a nonresident (already moved) at the time your NJ property closes.
If withholding exceeds your actual NJ tax liability, the difference is refundable — file Form A-3128 or your NJ nonresident return. This is not a separate tax; it's a prepayment of the same NJ income tax you'd otherwise owe.
No preferential rate — capital gains taxed exactly like wages
New Jersey has no separate capital gains schedule. All gains — short-term or long-term, stocks, real estate, business sales — are taxed as ordinary income at New Jersey's graduated rates, from 1.4% up to 10.75% for income above $1 million. There's no discount for how long you held the asset, and NJ's brackets haven't changed since 2020.
The "Exit Tax" is a name, not a separate tax
When it does apply, the withholding equals the greater of two amounts:
| Method | Calculation |
|---|---|
| Estimated tax on the gain | Up to 10.75% of the taxable gain |
| 2% floor | 2% of the total sale price — applies even with little or no gain |
That 2% floor is what catches people off guard: it's calculated on the full sale price, not the gain, so a seller with a small gain (or none at all, after the federal home-sale exclusion) can still have thousands withheld at closing — money that's refundable, but only after filing the right form.
New Jersey's capital loss rules are unusually strict
Unlike the federal system, New Jersey does not allow capital losses to carry forward to future years — an unused loss in a given year is permanently lost, not banked for later. Losses also can't offset gains in a different income category, or reduce wage income at all. This makes tax-loss harvesting timing more important in New Jersey than in most other states.
The home sale exclusion still applies
New Jersey conforms to the federal §121 primary residence exclusion — $250,000 (single) or $500,000 (married filing jointly) — so most homeowners selling a primary residence within those limits owe no NJ tax on the gain at all, even though NJ has no separate capital gains break generally.
New Jersey's ordinary-income capital gains treatment, the exit tax withholding mechanics (greater of estimated tax or 2% of sale price), and the resident-vs-nonresident distinction verified against multiple independent 2026 New Jersey tax guides, including matching worked examples on the 2% floor calculation.

Frequently asked questions
Before you sell property or investments in New Jersey.
Does New Jersey have a separate capital gains tax rate?
No. All capital gains are taxed as ordinary income under New Jersey's graduated brackets, from 1.4% to 10.75%, with no discount for long-term holdings.
Is the NJ "exit tax" really a separate tax?
No — it's a withholding requirement at closing, an estimated prepayment of the same NJ income tax owed on the gain. It only applies if you're a nonresident (already moved out of state) at the time of closing.
How is the NJ exit tax withholding calculated?
The greater of an estimated tax on the gain (up to 10.75%) or 2% of the total sale price — the 2% floor applies even if the actual gain is small or zero.
Can I get the withheld amount back if it's more than I actually owe?
Yes — overpaid withholding is refundable. File Form A-3128 or your NJ nonresident return to recover the difference.
Can I carry forward a capital loss in New Jersey?
No — unlike the federal system, New Jersey does not allow capital losses to carry forward to future tax years. An unused loss is permanently lost, and losses can't offset wage income at all.
