If you sell your house in New Jersey, you probably will not owe any income tax on the profit, because both the IRS and the state let you exclude up to $250,000 of gain as a single filer or $500,000 as a married couple filing jointly.1NJ Division of Taxation. Income Tax – Sale of a Residence Taxes when selling a house in NJ really come down to three separate things: income tax on any gain above that exclusion, a Realty Transfer Fee that every seller pays at closing regardless of profit, and, for sellers who have already moved out of state, an estimated tax payment collected at the closing table.
Figuring Out Your Actual Profit
The number that matters for income tax is your gain, not your sale price. Gain is what you walked away with, minus what the home cost you after adjustments.
Start with the sale price and subtract the costs tied to selling: broker commissions, attorney fees, title insurance you paid, and transfer fees. A $750,000 sale with $45,000 in selling costs gives an “amount realized” of $705,000.
Then calculate your adjusted basis. Begin with your original purchase price plus the closing costs and acquisition fees you paid when you bought the home. Add capital improvements made over the years — permanent upgrades that add value or extend the home’s life, such as a new roof, a finished basement, or an upgraded HVAC system. Routine repairs like patching drywall or fixing a faucet do not count.2Internal Revenue Service. Publication 551 (12/2025), Basis of Assets
If you ever claimed depreciation for a home office or rental use, your basis drops by the total depreciation you deducted or could have deducted, even if you never actually took the deduction.3Internal Revenue Service. Publication 551 (12/2025), Basis of Assets – Section: Decreases to Basis That mandatory reduction surprises people who estimate their tax on sale.
Your taxable gain is the amount realized minus the adjusted basis. That is the figure you run through the exclusion rules below.
The $250,000 and $500,000 Exclusion
Section 121 of the Internal Revenue Code lets you exclude up to $250,000 of gain on the sale of your principal residence, or up to $500,000 on a joint return when both spouses qualify.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence5Cornell Law Institute. N.J. Admin. Code 18:35-2.41NJ Division of Taxation. Income Tax – Sale of a Residence For most sellers in the state, that single rule wipes the income tax bill out entirely.
To qualify, you have to pass two tests. The ownership test: you owned the home for at least two of the five years before the sale. The use test: you lived in it as your primary residence for at least two of those same five years. The qualifying time does not have to be consecutive — 24 months total inside the five-year window is enough.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
Fell short of two years? You may still qualify for a partial exclusion if the sale is driven by a job relocation, a health issue, or certain other unforeseen circumstances. The partial exclusion is proportional: divide the time you did meet the tests by two years, then multiply by $250,000 or $500,000. A married couple selling after 15 months because of a qualifying job change would get 15/24 of $500,000, or $312,500.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
You can only use the exclusion once every two years. If you already claimed it on another sale within the prior two years, this sale does not qualify.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
If Your Gain Is Larger Than the Exclusion
Any gain above the exclusion is taxed. On the federal side, if you owned the home more than a year, the excess is a long-term capital gain, taxed at 0%, 15%, or 20% depending on your total taxable income for the year.6Tax Foundation. 2026 Tax Brackets and Federal Income Tax Rates Higher-income sellers may also owe the 3.8% Net Investment Income Tax, which applies when modified adjusted gross income exceeds $200,000 for single filers or $250,000 for joint filers.7Internal Revenue Service. Topic No. 559, Net Investment Income Tax Stacked together, the top federal rate on home-sale gain reaches 23.8%.
New Jersey has no separate capital gains rate. The excess gain is taxed as ordinary income on your NJ-1040, stacked on top of your other income, under the state’s bracket schedule that runs from 1.4% at the bottom to 10.75% on income above $1 million.8NJ Division of Taxation. NJ Income Tax Rates A large gain can push you into higher brackets than your usual income puts you in.
One wrinkle for anyone who used part of the home for business: depreciation claimed after May 6, 1997 is not sheltered by the Section 121 exclusion. That piece is taxed as unrecaptured Section 1250 gain, at a maximum federal rate of 25%.9Internal Revenue Service. 1997 Instructions for Form 4797 – Sales of Business Property Pure owner-occupants with no depreciation history can ignore this.
The Realty Transfer Fee Every Seller Pays
Separate from income tax, New Jersey charges a Realty Transfer Fee on every deed. The seller pays, and the county clerk collects it when the deed is recorded.10NJ Division of Taxation. Realty Transfer Fee There is no exclusion based on how long you lived in the home. If a deed is recorded, the fee is owed.
The fee is calculated per $500 of sale price under a tiered schedule, with higher rates kicking in at higher price bands. On a $500,000 home, the standard RTF works out to roughly $2,480.10NJ Division of Taxation. Realty Transfer Fee It shows up as a line item on your closing statement, and sellers routinely underestimate it because the discussion around home-sale taxes tends to focus on income tax.
Sales over $1 million trigger a supplemental Graduated Percent Fee on top of the standard RTF, starting at 1% of the entire sale price (not just the amount over $1 million) and climbing in bands up to 3.5% on sales above $3.5 million.10NJ Division of Taxation. Realty Transfer Fee A $1.5 million closing owes an additional $15,000 on top of the standard RTF. Budget for it early.
Sellers who are 62 or older, blind, or disabled pay a reduced RTF schedule, roughly half the standard rate.11NJ Division of Taxation. Realty Transfer Fees (RTF) Frequently Asked Questions Certain transfers are fully exempt — transfers between spouses, deeds recorded within 90 days of a divorce decree, and corrective deeds, among others — though the exemption still has to be noted on the deed.10NJ Division of Taxation. Realty Transfer Fee
If You Have Already Moved Out of State
Residency at the time of closing changes what happens at the closing table. Every seller files a GIT/REP form, which the county clerk requires before recording the deed. Residents and nonresidents file different versions, and only nonresidents hand over money.12State of New Jersey – Division of Taxation. Buying or Selling a Home in New Jersey
If you are a New Jersey resident at closing, you sign Form GIT/REP-3 certifying residency, and no estimated payment comes out of your proceeds. You report any gain on your NJ-1040 at tax time like any other income.14NJ.gov. GIT/REP-3 Seller’s Residency Certification/Exemption
If you are a nonresident at closing, you file Form GIT/REP-1 and must make an estimated Gross Income Tax payment on the spot. The payment equals 10.75% of the gain or 2% of the total sale price, whichever is greater.13NJ Division of Taxation. FAQs on GIT Forms Requirements for Sale of Real Property The 10.75% figure is the state’s top marginal income tax rate, applied to your entire gain regardless of what bracket your real income sits in.
Even sellers with no gain owe the 2% minimum. On a $600,000 sale at a loss, the state still withholds $12,000 from your proceeds.15NJ Division of Taxation. FAQs on GIT Forms Requirements for Sale of Real Property You get it back by filing a NJ-1040NR nonresident return showing your actual tax liability, but the money is tied up for months in the meantime.
Real estate agents often call this the “New Jersey exit tax.” The label is misleading. There is no separate exit tax. The closing payment is an estimated income tax deposit, credited against whatever you actually owe on the NJ-1040NR. If you qualify for the Section 121 exclusion and the real tax is zero, the full deposit is refunded. The catch is that many nonresident sellers never realize they have to file an NJ-1040NR to claim it, so the refund never arrives.
If You Inherited the House
Inherited property gets different starting math. Your basis is the fair market value of the home on the date the prior owner died, not what they originally paid.16Internal Revenue Service. Gifts and Inheritances This stepped-up basis usually shrinks or eliminates the taxable gain.
If a parent bought a home for $120,000 in 1985 and it was worth $550,000 when they died, your basis is $550,000. Sell for $575,000, and your taxable gain is $25,000, not $455,000. You generally will not qualify for the Section 121 exclusion on an inherited home unless you moved in and used it as your own principal residence for two of the five years before selling. Without meeting that test, the gain is taxed at ordinary capital gains rates, even if it is small after the step-up.
The GIT/REP rules still apply. If you live outside New Jersey and sell inherited New Jersey property, you make the nonresident estimated payment at closing like any other out-of-state seller.
Reporting the Sale After Closing
Your settlement agent may issue a Form 1099-S reporting the gross sale proceeds to the IRS. The agent is not required to issue one if you certify in writing that the home was your principal residence and the full gain qualifies for the Section 121 exclusion.17IRS.gov. Instructions for Form 1099-S Proceeds From Real Estate Transactions
On the federal return, you must report the sale on Schedule D and Form 8949 if you received a 1099-S, even when the entire gain is excluded. You also must report when your gain exceeds the exclusion. If no 1099-S was issued and your gain is fully excludable, you do not have to report the sale.18Internal Revenue Service. Topic No. 701, Sale of Your Home
Hold on to every document that backs up your gain calculation: closing disclosures from both the purchase and the sale, receipts for capital improvements, and records of depreciation. The IRS can ask years later, and reconstructing numbers after the fact is far harder than keeping a folder.
On the state side, New Jersey residents report the gain on the NJ-1040 and apply the exclusion. Nonresidents file the NJ-1040NR to report the gain and claim credit for the estimated payment collected at closing; filing is the only way to recover any overpayment.12State of New Jersey – Division of Taxation.
