NJ Exit Tax Calculator: How to Use It and What the Number Means

If you're selling a New Jersey property from out of state, or you've already moved, the state collects an estimated income tax payment right at the closing table. Most people call it the "exit tax." Our NJ exit tax calculator is the fastest way to get a real number before you sign anything. Know every fee before closing, so the number you hear at settlement is the number you actually keep. We walk through every input the calculator needs, show two full worked examples, and explain who pays nothing at all. For the background on how this tax was created and why it exists, see the full NJ exit tax guide. The NJ exit tax calculator sits just below the quick answer. Plug your numbers in, then come back here for the explanation.

Reading the Result: Two Worked Examples

On a $400K sale with $250K basis, gain-based wins at $14,512.50; with $390K basis, the 2% floor of $8,000 wins instead.

The NJ exit tax calculator gives you two figures and highlights the larger one. Here is how that plays out in real South Jersey transactions. Example one: you sell a Gloucester County rental for $400,000. Your adjusted basis is $250,000 and selling costs total $15,000. Your gain is $400,000 minus $250,000 minus $15,000, which equals $135,000. The gain-based amount is 10.75% × $135,000 = $14,512.50. The 2% floor is 2% × $400,000 = $8,000. The gain side wins. You bring $14,512.50 to the closing table. Example two: you sell a Camden County row home you inherited for $400,000, but the stepped-up basis is $390,000 and selling costs are $5,000. Your gain is just $5,000. The gain-based amount is 10.75% × $5,000 = $537.50. The 2% floor is 2% × $400,000 = $8,000. The floor wins. You owe $8,000 at closing even though you barely made a dime on the sale. That second scenario is the one that blindsides heirs the most.

The Hot Take on Gain vs. Floor

Most sellers panic about the exit tax rate, but the 2% floor, not the 10.75% rate, is the calculation that most often surprises low-equity sellers.

Most sellers think the exit tax is a penalty for leaving New Jersey. It isn't. It's a prepayment of income tax you'd owe anyway. Mixing up the two makes sellers panic and price their home wrong. The 10.75% rate sounds scary, but it only applies to your gain. The 2% floor is the number that actually hurts low-equity sellers. That hits hardest for out-of-state heirs who inherited a property that gained only modest value over time. We've worked through this math with out-of-state sellers across Camden, Atlantic, Ocean, and Cumberland counties. The mistake is almost always the same. Sellers fixate on the rate and miss the floor entirely. Run the NJ exit tax calculator before you accept any offer. Do it before, not after.

Who Pays Nothing at Closing

NJ residents on closing day (GIT/REP-3 Box 1) and principal-residence sellers (Box 2) owe nothing at closing regardless of gain size.

Two groups skip the payment entirely by filing the GIT/REP-3 form. The first group covers anyone who is a New Jersey resident on the actual day of closing, Box 1. If New Jersey is still your home (your domicile) on closing day, you are covered. The second group is sellers who pass the principal-residence test, Box 2. You must have lived in the home as your main residence for 2 of the last 5 years. That exemption holds even when your gain runs larger than the federal Section 121 exclusion of $250,000 for single filers or $500,000 for married couples. Box 2 on the GIT/REP-3 exists as a separate test from the federal exclusion. Heirs living in Pennsylvania, Delaware, or Florida, a common pattern in Atlantic and Cape May counties, almost always face the payment.

A Conceded Reality About the 2% Floor

The 2% floor surprises low-equity sellers far more often than the 10.75% gain rate does, especially on inherited properties with stepped-up basis near sale price.

We'll be honest: on a thin-equity sale the 2% floor can make selling as a nonresident feel like a penalty, and no calculator changes that. What helps is knowing it is refundable and planning your cash around a refund that pays no interest. Now it is the first thing we flag. If you are selling a parent's Salem or Cumberland County home where the stepped-up basis is close to today's market value, the 2% floor will dominate the calculator output every time. The gain side is tiny, sometimes zero, but 2% of the sale price runs into the thousands regardless. That reality shapes how we build the seller net sheet for every out-of-state seller we work with. That is the standard we hold ourselves to.

Exit Tax vs. Realty Transfer Fee: Two Different Closing Costs

Overpayments Come Back, But With No Interest

NJ exit tax overpayments are refunded via the NJ-1040NR after year-end with no interest paid on the amount held.

The exit tax is a prepayment, not your final bill. After the calendar year closes, you file a New Jersey NJ-1040NR nonresident return. Your actual income tax on the gain is calculated at the correct bracket rate for your total NJ-source income. That number may be less than what was withheld at closing, and the state refunds the difference. There is one catch: the state pays you zero interest on the money it held. If your closing happened in February and you file in April of the following year, you have given New Jersey a 14-month interest-free loan on the overage. That is not a reason to skip the payment. It is a reason to track the number carefully, file promptly, and get your money back. Know every fee before closing so the number you hear is the number you keep. Surprises on the back end cost you just as much as surprises at the table.

The NJ Exit Tax Calculator and Selling Costs: What Lowers the Gain

Selling costs reduce the taxable gain for the 10.75% calculation but have no effect on the 2% floor, which is always based on the full sale price.

Selling costs come off the gain, not off the sale price. That gap matters when you are deciding whether to sell as-is or fix things up first. Say you spend $10,000 getting a Cape May County vacation home ready to list. That $10,000 does not lower the 2% floor. It only cuts the gain on the 10.75% side of the NJ exit tax calculator. On a high-gain sale, that shift moves the tax a little. On a low-equity sale where the floor is running the show, that $10,000 repair spend changes nothing on the exit tax line. That is why we never suggest pre-sale repairs for out-of-state sellers without running the full calculator first. The numbers often show that selling as-is, with a fast close, puts more money in your pocket than repairing and listing ever would. If you are weighing that choice right now, see repairs you cant afford for a plain breakdown of when repairs pay off and when they do not.
