New Jersey Exit Tax: What It Is, How It Works, and How to Get Your Money Back

The term “NJ exit tax” is common shorthand for a real estate withholding requirement that surprises many homeowners selling their NJ property and moving out of state. It’s not actually a tax on leaving New Jersey — it’s a withholding mechanism to ensure sellers pay any NJ income taxes owed on the sale. But the amount withheld at closing can be thousands of dollars more than what you actually owe, which means you need to file a NJ return to get your refund.

What the “NJ Exit Tax” Actually Is

Under NJ law, when a nonresident sells NJ real property, the buyer (or title company) is required to withhold New Jersey income tax at closing. The withheld amount is sent to the NJ Division of Taxation. The seller then files a NJ nonresident return (NJ-1040NR) and reconciles — any amount withheld above your actual tax liability gets refunded.

The same rule applies to NJ residents who are moving out of state at the time of sale. Even if you currently live in NJ, if you sign a Seller’s Residency Certification (GIT/REP-3) indicating you will not be a NJ resident on the closing date, you’re treated as a nonresident seller — and the withholding applies.

How Much Is Withheld?

The withholding is calculated as the higher of:

8.97% of the gain on the sale (for sellers with gains above $500,000 in NJ — the top NJ income tax rate on upper-income nonresidents), or
2% of the total sale price

For a $600,000 home sale, the 2% floor means $12,000 withheld at closing regardless of your gain. If your actual NJ tax on the gain is only $3,000, you’d be owed a $9,000 refund after filing. This is why people call it an “exit tax” — it feels punishing at closing, even though you get most of it back.

Who It Applies To

Nonresidents selling NJ real property — people who live outside NJ and own NJ property
Residents moving out of NJ before or at closing — if you’re selling your home as part of a relocation and won’t be a NJ resident on closing day
Estates and trusts selling NJ property on behalf of nonresident decedents or beneficiaries

Who Is Exempt

NJ residents who remain NJ residents after the sale — you file as a NJ resident and pay NJ income tax normally; no upfront withholding required. File the GIT/REP-3 at closing affirming your NJ residency.
Sales under $1,000 total price
Certain transfers like foreclosures, court orders, or transfers between spouses

How NJ’s Capital Gains Tax on the Sale Works

New Jersey taxes capital gains on real estate as ordinary income — there’s no preferential long-term capital gains rate in NJ. The gain is your sale price minus your adjusted basis (purchase price plus improvements, minus depreciation if any). Your gain is then taxed at your NJ income tax rate — which for most nonresidents with a single NJ transaction will be 6.37% or higher.

The federal $250,000/$500,000 home sale exclusion (Section 121) does not apply for NJ purposes. If you exclude $250,000 of gain federally because it’s your primary residence, NJ still taxes that gain. This is a major difference: NJ does not conform to the Section 121 exclusion.

The Filing Process: Getting Your Withholding Back

To reconcile and receive your refund:

File NJ Form NJ-1040NR (nonresident return) for the year of the sale
Report the NJ-sourced income from the real estate sale
Apply the withholding credit (shown on the GIT/REP forms from closing) against your calculated NJ tax liability
If withholding exceeds your tax, the difference is your refund — typically processed within 6–12 weeks of filing

Keep all closing documents, including the GIT/REP forms (GIT/REP-1 or GIT/REP-2) that document the amount withheld. These are your proof of the withholding credit.

Planning Considerations: Timing Your Move

If you’re a NJ resident who plans to sell your home as part of a move out of state, the timing of when you establish residency elsewhere matters significantly:

Sell while still a NJ resident: File as a full-year NJ resident. No withholding at closing. NJ Section 121 doesn’t apply, so you owe NJ tax on your gain (minus any NJ basis adjustments). You benefit from the full year’s NJ deductions and exemptions.
Sell after establishing out-of-state residency: You’re a nonresident seller. Withholding applies at closing. You file NJ-1040NR for the NJ-sourced income only. You might owe less overall if your new state has a lower or zero income tax and the NJ withholding covers most of your NJ liability.

For sales with large gains, consult a NJ tax attorney or CPA before finalizing your move timeline. The difference in NJ tax owed can be significant depending on your circumstances.

Common Questions

Can I avoid the withholding if I’m not selling to avoid taxes?

The withholding is automatic for nonresident sellers. You can’t opt out of it. Your recourse is to file the NJ return promptly and receive your refund quickly. Some sellers arrange for the withholding amount to be held in escrow by the title company until the return is filed, but this requires coordination and agreement from all parties.

Does this apply to rental properties, not just primary homes?

Yes — it applies to all NJ real property sold by nonresidents, including investment properties, vacation homes, and rental properties. The withholding rules are the same regardless of property type.

What if the property sold at a loss?

The minimum 2% of sale price withholding still applies even on a loss. You’d then file the NJ return showing no gain (or a loss), apply the withholding credit, and receive a full refund. The NJ Division of Taxation doesn’t waive withholding upfront even for known losses.
