New Jersey Capital Gains Tax, Explained

The federal system rewards patience: hold an asset over a year and your rate drops to 0%, 15%, or 20%. New Jersey ignores the holding period entirely. Every dollar of gain, whether it's stock held for a decade or a house flipped in six months, lands on your New Jersey return as ordinary income and climbs the same graduated bracket ladder as your salary.

New Jersey runs seven brackets, from 1.4% on the first $20,000 of income up to 10.75% on taxable income over $1,000,000, the rate New Jersey residents know as the millionaires tax. Most working professionals with a meaningful capital gain land in the 6.37% band, which covers income from $75,000 up to $500,000, but a large one-time gain, a business sale, a concentrated stock position, an investment property, can push a household into the 8.97% or 10.75% brackets for that year even if their normal income never comes close.

Search "New Jersey exit tax" and you'll find a lot of confusion, some of it from people who should know better. Here's the straight answer: there is no separate New Jersey exit tax. New Jersey does not charge an extra tax for the privilege of leaving the state. What actually exists is an estimated tax withholding requirement that applies at closing when a nonresident sells New Jersey real estate, formally known as the Gross Income Tax requirements under GIT/REP.

Here's how it actually works. When you sell New Jersey real estate and you are not a New Jersey resident at the time of closing, the closing agent withholds an estimated payment toward the state tax you'll eventually owe on the gain, and submits it with the deed when the sale is recorded. The withholding is the greater of two calculations: 2% of the total sale price, or the estimated gain multiplied by the top Gross Income Tax rate of 10.75%. On a property with real appreciation, the gain-based number is almost always larger, so that's typically what gets withheld.

Nonresident sellers document the payment on Form GIT/REP-1. Sellers who qualify for an exemption, most commonly because they are still New Jersey residents, file Form GIT/REP-3 instead and owe nothing at closing. This is the detail that trips people up: the rule targets nonresidents specifically. A longtime New Jersey homeowner who sells while still living in the state pays nothing extra at closing. The same homeowner, having already relocated to Florida or North Carolina before the sale closes, gets hit with the withholding, even on a property they've owned for decades.

New Jersey's state tax stacks on top of, not instead of, the federal capital gains system. Long-term gains still get the federal 0%, 15%, or 20% rate depending on total taxable income, and the 3.8% Net Investment Income Tax applies once modified adjusted gross income clears $200,000 for single filers or $250,000 for married filing jointly. Short-term gains, held one year or less, get no discount at any level: ordinary federal brackets up to 37%, and ordinary New Jersey brackets up to 10.75%.

That two-layer stack, federal plus state, is why a large short-term gain for a high-income New Jersey seller is one of the most expensive events in the state's tax landscape, with combined marginal rates that can clear 45%.

Primary residences get the federal Section 121 exclusion, $250,000 of gain excluded for single filers, $500,000 for married filing jointly, and New Jersey generally follows the federal exclusion for its own income tax purposes. A large amount of New Jersey home appreciation, particularly in North Jersey and the Jersey Shore markets, falls comfortably inside that exclusion. What doesn't fit inside it is taxed at your regular New Jersey bracket rate, on top of federal capital gains tax.

Rental and investment property sellers face an extra layer that primary-residence sellers don't: depreciation recapture. Every year of depreciation deducted against a rental property reduces its basis, and the portion of the gain attributable to that depreciation is recaptured federally at a rate up to 25%, then still counted as ordinary income by New Jersey on top of that. A rental sold after a decade of ownership can easily carry tens of thousands of dollars in recaptured depreciation baked into the gain, and New Jersey taxes all of it at ordinary rates alongside the appreciation itself.

Investors looking to defer that recognition entirely, rather than simply managing the rate, should look at a 1031 exchange, which New Jersey generally follows for its own income tax purposes when the exchange is structured correctly at the federal level.

Two patterns show up constantly in New Jersey capital gains questions. The first is the Jersey Shore vacation home, a property that has appreciated for decades and doesn't qualify for the Section 121 exclusion because it was never the owner's primary residence. That gain is fully taxable, at both the federal and New Jersey level, with no exclusion to soften it. If the property has ever been rented out, depreciation recapture applies on top.

The second is the New York commuter who lives in New Jersey and works across the river. New Jersey and New York have long had reciprocal tension over where income gets taxed, but for capital gains specifically, the rule is straightforward: your state of residence taxes your capital gains, not your state of employment. A New Jersey resident who commutes into Manhattan for work still pays New Jersey tax, not New York tax, on the sale of stock, a business interest, or property located outside New York. New York real estate itself is the one asset type that stays taxable by New York regardless of where the owner lives.
