After a home closes, deciding what to do with home sale proceeds comes down to two steps in order: settle the federal tax question, then direct the net cash toward your next home, your debts, and your long-term savings. Most sellers owe no federal tax at all thanks to the primary-residence exclusion, which shields up to $250,000 of gain for a single filer and $500,000 for a married couple filing jointly.1Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Get that piece right, then work down the priority list.
What Actually Lands in Your Account
The sale price is not the wire amount. Before the settlement agent sends you anything, every lien on the property gets paid off: your remaining mortgage balance, accrued interest since your last payment, any prepayment penalty, and the balance on any home equity line or second mortgage. The buyer is entitled to clean title, so nothing survives closing.
Real estate commissions come next. Commission structures have been shifting since 2024, and the total across both agents typically lands between 4.5% and 6% of the sale price, though the split and who pays what is more negotiable than it used to be. On a $400,000 sale, that works out to roughly $18,000 to $24,000.
Transfer taxes, prorated property taxes, recording fees, and (in some states) an attorney at closing round out the deductions. Transfer tax rates run from nothing to about 3% depending on state and locality. By the time every obligation is satisfied, net proceeds on a $400,000 sale might be $50,000 or more below the headline number. Work from that net figure, not the contract price, when you plan what happens next.
The Tax Question, First
The Section 121 exclusion is the single most valuable break for home sellers. A single filer can exclude up to $250,000 of gain from federal income tax; a married couple filing jointly can exclude up to $500,000.1Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence For most sellers, that erases the tax bill entirely.
To qualify, you have to pass the ownership and use test: owned the home and lived in it as your primary residence for at least two of the five years leading up to the sale.2eCFR. 26 CFR 1.121-1 – Exclusion of Gain From Sale or Exchange of a Principal Residence The two years don’t have to be consecutive. For the $500,000 joint exclusion, both spouses must meet the use requirement, though only one needs to satisfy the ownership test.1Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
Your gain is not just sale price minus what you originally paid. From the sale proceeds you subtract your adjusted basis: the original purchase price plus qualifying improvements made over the years plus certain closing costs from both the purchase and the sale.
If You Have to Sell Before Two Years
A qualifying job move, a health-related move, or certain unforeseen circumstances let you claim a prorated exclusion.3Internal Revenue Service. Publication 523, Selling Your Home Divide the months you met the ownership-and-use test by 24, then multiply by the full exclusion amount. A single filer who owned for 15 months before a qualifying job transfer would get 15/24 × $250,000 = $156,250 of shielded gain. Many early sellers still end up owing nothing.
Improvements That Cut the Taxable Gain
Every dollar you spent on qualifying improvements adds to your cost basis and reduces the gain the IRS measures. The line the IRS draws is between improvements (adds value, extends useful life, or adapts the home to a new use) and routine maintenance (fixing a leaky faucet, patching cracks, touch-up painting).3Internal Revenue Service. Publication 523, Selling Your Home
Qualifying work includes:
- Additions: bedrooms, bathrooms, decks, garages, porches
- Systems: central air conditioning, new wiring, security systems, water filtration
- Exterior work: new roof, new siding, storm windows, insulation
- Interior work: kitchen remodels, new flooring, built-in appliances, fireplaces
- Grounds: landscaping, driveways, fences, retaining walls, swimming pools
One detail worth knowing: repair-type work done as part of a larger remodel gets folded in. Replacing one cracked window is a repair. Replacing every window as part of a renovation is an improvement, and the whole cost adds to basis.3Internal Revenue Service. Publication 523, Selling Your Home Sellers who can’t produce receipts leave money on the table.
Rates If Your Gain Exceeds the Exclusion
Overage past the exclusion gets taxed at long-term capital gains rates when you owned the home for more than a year. Most sellers who owe anything land in the 15% bracket; the 20% rate applies only at very high income levels.4Tax Foundation. 2026 Tax Brackets and Federal Income Tax Rates High earners face an additional 3.8% Net Investment Income Tax once modified adjusted gross income exceeds $200,000 for single filers or $250,000 for joint filers, thresholds that are not indexed for inflation.5Internal Revenue Service. Net Investment Income Tax A seller in the top bracket with NIIT exposure pays 23.8% on the gain above the exclusion.
Reporting the Sale
The IRS usually knows about your sale. The settlement agent generally files Form 1099-S reporting the proceeds. If the sale price is $250,000 or less ($500,000 for a married seller) and you sign a written certification that the home was your primary residence and the full gain qualifies for exclusion, the agent doesn’t have to file.6Internal Revenue Service. Instructions for Form 1099-S, Proceeds From Real Estate Transactions
When a 1099-S is issued, report the sale even if the exclusion covers everything. Use Form 8949 to list the property, dates, proceeds, and adjusted basis, and carry the result to Schedule D on your Form 1040.7Internal Revenue Service. Instructions for Form 8949 If you qualify for the full exclusion and no 1099-S was filed, you generally don’t need to report the sale.
Estimated Tax If You Do Owe
If the exclusion doesn’t cover the full gain, you may owe a five-figure tax bill, and the IRS doesn’t wait until April. Miss the estimated payment for the quarter in which you closed and you face an underpayment penalty on top of the tax. The quarterly deadlines are April 15, June 15, September 15, and January 15 of the following year.8Internal Revenue Service. Estimated Tax
The safe harbor rule protects you if you’ve paid at least 90% of the current year’s tax or 100% of last year’s (110% if your prior-year adjusted gross income exceeded $150,000).9Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty For someone with steady W-2 income, bumping your withholding at work for the rest of the year is often simpler than cutting a separate check to the IRS.
Funding Your Next Home
For most sellers, the largest slice of net proceeds goes straight into the next property. A larger down payment lowers your monthly payment and, at 20% or more down, spares you private mortgage insurance, which can run $100 to $300 per month on a typical loan. Sellers often coordinate a simultaneous closing so funds move directly from one escrow to another.
If you already closed on the new home before selling the old one, mortgage recasting can put the proceeds to work without a refinance. You apply a lump-sum principal payment, and the lender recalculates your monthly payment based on the reduced balance while keeping the original interest rate and term. Most lenders require a minimum payment of $5,000 to $10,000 and charge a fee between $150 and $500. No credit check, appraisal, or new closing costs. Government-backed loans (FHA, VA, USDA) generally are not eligible.
Budget a cushion for the new place. Moving, painting, flooring, and appliances can run several thousand dollars, and pouring every last dollar into the down payment only to furnish on credit cards defeats the purpose.
Where the Rest Should Go
If you’re downsizing, relocating to a cheaper market, or simply have surplus after years of equity growth, the money left over has a rough priority order:
- Emergency fund. Three to six months of living expenses in a high-yield savings account. If yours is thin, this is the moment to fix it.
- High-interest debt. Credit cards and personal loans charging 20% or more are guaranteed negative returns. Paying them off is among the highest-return moves available, and it frees monthly cash flow immediately.
- Retirement accounts. You can’t drop a lump sum into a 401(k) or IRA past the annual limit, but you can use proceeds to cover living expenses while maxing out payroll contributions for the rest of the year. The money reaches the retirement account indirectly.
- Taxable investments. Once the emergency fund is solid, the high-interest debt is gone, and retirement contributions are maxed, a diversified brokerage account has no contribution ceiling and no early-access penalty.
A six-figure balance sitting in a checking account earning next to nothing loses purchasing power to inflation every month. Even without a final plan, moving the funds into a high-yield savings account or money market fund while you decide costs nothing and earns something.
Two Things People Assume Apply But Don’t
1031 Exchanges Are Not for Your Home
You cannot roll home-sale proceeds into another property tax-free using a 1031 like-kind exchange. Section 1031 applies only to property held for investment or business use; a primary residence or vacation home does not qualify.10Internal Revenue Service. Like-Kind Exchanges Under IRC Section 1031 The Section 121 exclusion is the mechanism Congress created for personal residences, and the two provisions operate independently.
FIRPTA Withholding for Foreign Sellers
Non-resident foreign sellers of U.S. real estate face a separate rule. Under the Foreign Investment in Real Property Tax Act, the buyer must withhold 15% of the gross sale price and remit it to the IRS at closing.11Internal Revenue Service. FIRPTA Withholding That withholding comes off the top regardless of actual profit. If it exceeds true tax liability, the seller can file a U.S. return to claim a refund, or apply for a withholding certificate before closing to reduce the amount withheld.
