The New Jersey Exit Tax on a Home Sale: The 2% Withholding Nonresidents Pay at Closing, and How to Get It Back.

A couple moved from Bergen County to Naples, Florida two years ago and finally sold the New Jersey house this spring. At the closing table, the settlement statement showed a line they had never budgeted for: a five-figure payment to the State of New Jersey, which the title company called the exit tax. The New Jersey exit tax on a home sale has a terrible name, because it is not a tax on leaving at all. It is a mandatory prepayment of estimated income tax that nonresident sellers must make before the county clerk will record the deed. If you understand what it actually is, you can plan for it, sometimes avoid it entirely, and get back every dollar you did not truly owe.

The rule comes from P.L. 2004, c. 55, effective August 1, 2004, codified at N.J.S.A. 54A:8-8 through 54A:8-10. When a nonresident individual, estate, or trust sells New Jersey real estate, the county recording officer cannot record the deed unless it arrives with a completed GIT/REP form and, where one is due, an estimated gross income tax payment. Under N.J.S.A. 54A:8-9, that payment is the gain on the sale multiplied by the highest gross income tax rate, currently 10.75%, but never less than 2% of the total consideration stated in the deed. Note what that is not. It is not a separate tax, not a penalty for moving, and not money the state keeps automatically. It is a deposit against your actual New Jersey income tax for the year, and the actual tax on the gain is almost always far less than what the formula collects at closing.

Everything runs through the GIT/REP forms, and which one you sign determines whether money leaves the closing. A nonresident seller with no exemption signs the GIT/REP-1, the Nonresident Seller's Tax Declaration, and remits the estimated payment at recording. A GIT/REP-2 covers the less common case of paying the Division of Taxation directly before closing. The form most sellers want is the GIT/REP-3, the Seller's Residency Certification/Exemption. Check a box on that form and no payment is due at closing. Box 1 is for New Jersey residents, who settle any tax on the sale through their regular NJ-1040 and never face the withholding. Box 2 is for property used exclusively as a principal residence as defined in 26 U.S.C. §121, the federal home sale exclusion of $250,000 for single filers and $500,000 for joint filers. Other boxes cover deeds for under $1,000 of consideration, transfers where the seller receives no net proceeds, foreclosures and deeds in lieu, and gains not recognized federally under §1031 or §1033. The exemption certification happens at the closing table, so a seller who does not know the boxes exist simply pays.

The trap inside the formula is the floor. The estimated payment is 10.75% of the gain, but never less than 2% of the sale price. A nonresident who sells a $500,000 condo for exactly what she paid has zero gain and zero eventual tax, yet still writes a $10,000 check at closing unless an exemption box applies, such as the GIT/REP-3 certification that the seller is receiving no net proceeds from the sale. Selling at a modest loss while walking away with proceeds does not fit that box. Those sellers pay the 2% and recover it later. The floor exists because the state has no way to audit your basis at the recording window, so it takes the deposit first and lets you prove the numbers afterward.

That gap is the whole story. The closing formula prices every dollar of gain at the top bracket, 10.75%, a rate that does not even apply until taxable income passes $1,000,000. A couple whose only New Jersey income is a $300,000 gain never gets near it. The state is holding roughly $17,000 of their money interest-free, and it stays held until the sellers ask for it back.

There are two ways home. The fast lane is Form A-3128, the claim for refund of the estimated payment, which can be filed with the Division of Taxation as soon as the deed is recorded, rather than waiting for tax season. It goes to the Taxpayer Accounting Branch with the settlement statement or Closing Disclosure attached, plus documentation of your basis and selling expenses showing the actual gain. Incomplete claims are returned, not held, so the basis workpapers matter. The slow lane is simply filing the NJ-1040NR nonresident return after year-end, reporting the actual gain, and claiming the closing payment as tax already paid. Either way the overpayment comes back. The sellers who lose are the ones who assume the closing payment was a final tax and never file anything, which happens more often than you would think, because nothing in the process tells them a refund exists.

For people who have already moved, the most valuable planning is the calendar. Section 121 requires that you owned and used the home as your principal residence for two of the five years before the sale, which means a mover keeps the exclusion, and the GIT/REP-3 box 2 exemption, for roughly three years after leaving. Sell inside that window and a former New Jersey couple excludes up to $500,000 of gain federally and checks a box instead of writing a check. Let the house sit as a rental past the window and both benefits die together, a problem I cover in more detail in converting a rental back to a primary residence. And if the gain exceeds the exclusion, box 2 still works at recording; the seller then remits estimated tax on the excess with an NJ-1040-ES afterward. One more distinction worth keeping straight: the exit tax is refundable prepayment, but the Realty Transfer Fee and the mansion tax are real transfer taxes that nobody refunds. Since P.L. 2025, c. 69 took effect on July 10, 2025, the mansion tax falls on sellers, not buyers, at graduated rates from 1% on sales over $1 million to 3.5% over $3.5 million. None of this involves a residency fight, unlike New York's 183-day statutory residency test; New Jersey does not care where you live, only that it gets paid before the deed records.
