Calculating capital gains tax on a home sale in Ohio comes down to one formula: sale price minus selling costs minus your adjusted basis equals the gain, and most primary-residence sellers owe $0 on that gain in 2026 because the federal exclusion wipes out the first $250,000 (single) or $500,000 (married filing jointly) of profit. The catch is the exclusion only applies if you owned and lived in the home as your primary residence for at least two of the last five years — rental property, vacation homes, and most inherited property follow different rules, and high earners can still owe an extra 3.8% surtax on top of the federal and Ohio tax.
- Capital gains tax on a home sale in Ohio combines federal rates of 0-20% with Ohio's income tax, topping out near 3.5% in 2026.
- Most sellers owe $0 thanks to the $250,000 (single) or $500,000 (married) Section 121 exclusion.
- The formula is sale price minus selling costs minus adjusted basis equals your taxable gain before any exclusion.
- Sellers with income above $200,000 (single) or $250,000 (married) may also owe the 3.8% Net Investment Income Tax.

Why this matters
A lot of Southern Ohio sellers assume they owe tax on the full sale price, and it scares people out of listing when they don't need to be scared. Sandlin Realtors works with sellers across Portsmouth, Scioto County, Wheelersburg, Lucasville, Otway, Rarden, and South Webster, and the tax conversation comes up on almost every listing appointment. Getting the calculation right before you list changes whether you set your price around net proceeds or around a tax bill that never actually shows up.
How do you calculate capital gains tax on a home sale in Ohio?
Run the numbers in this order:
- Start with your sale price — the final contract price, not the list price.
- Subtract selling costs — agent commission, title fees, and the Ohio real estate conveyance fee.
- Subtract your adjusted basis — what you paid for the home plus documented capital improvements (roof, addition, HVAC replacement), minus any depreciation claimed if it was ever a rental.
- The result is your gain.
- Apply the Section 121 exclusion if you owned and lived in the home as your primary residence for two of the last five years.
- Whatever gain remains is taxed at your federal long-term capital gains rate plus Ohio's income tax rate.
Here's what that looks like for a single filer selling a home in Scioto County in 2026:
| Step | Line item | Amount |
|---|---|---|
| 1 | Sale price | $310,000 |
| 2 | Selling costs (commission, title, conveyance fee) | -$21,000 |
| 3 | Adjusted basis (purchase price + improvements) | -$195,000 |
| 4 | Gain before exclusion | $94,000 |
| 5 | Section 121 exclusion (single) | -$94,000 |
| 6 | Taxable gain | $0 |
That seller pays $0 in capital gains tax because the gain never exceeds the $250,000 exclusion. The math changes fast for a long-held home or a couple selling a property that's appreciated past $500,000 combined — the excess above the exclusion is what actually gets taxed.
Primary residence exclusion: $250,000 (single) or $500,000 (married)
This is the number that decides most outcomes. To qualify for the full exclusion:
- You must have owned the home for at least two of the five years before the sale.
- You must have used it as your primary residence for at least two of those five years (the two years don't need to be consecutive).
- You can't have used the exclusion on another home sale in the two years before this one.
Sellers who don't meet the full two-year test — job relocation, a health issue, or another unforeseen circumstance — can sometimes claim a partial exclusion prorated by how much of the two years they actually lived there. This exclusion has nothing to do with buying another home; that old rollover rule disappeared from the tax code in 1997.
Federal long-term capital gains rates: 0%, 15%, and 20% on the gain above your exclusion
Any gain that survives the exclusion is taxed federally at 0%, 15%, or 20%, depending on your total taxable income for the year. Two conditions matter here:
- You must have owned the home for more than one year to qualify for these long-term rates. Sell sooner and the gain is taxed as ordinary income at your regular federal bracket, which is almost always worse.
- The rate that applies is based on your total income, not just the gain — a big one-time gain can push you into a higher bracket for that tax year.
Most sellers with a moderate income and a gain in the tens of thousands of dollars land in the 15% federal bracket once the exclusion is applied.
Ohio's tax bite: up to 3.5% on top of the federal bill
Ohio has no separate capital gains tax rate. Instead, taxable capital gains get added to your other income and taxed under Ohio's graduated income tax brackets, which top out around 3.5% for higher earners in 2026. That's meaningfully lower than the capital gains treatment in many other states, which is one reason Southern Ohio sellers often come out ahead compared to sellers in higher-tax markets. The Ohio real estate conveyance fee paid at closing is a separate line item — it reduces your net proceeds but isn't part of the capital gains calculation itself.
Verdict: for most primary-residence sellers who've lived in the home two of the last five years, the real capital gains tax bill in Ohio is $0 — the exclusion, not the tax rate, does the heavy lifting.
Why your capital gains tax bill varies
- How long you owned and lived in the home — meeting the two-of-five-year test is the single biggest factor.
- Whether the property was a primary residence, a rental, or inherited — each triggers different basis and exclusion rules.
- Documented capital improvements — a new roof, an addition, or a major system replacement raises your basis and lowers your taxable gain, but only if you kept receipts.
- Your total taxable income for the year — this sets which federal bracket (0%, 15%, or 20%) applies to any leftover gain.
- Filing status — married filing jointly doubles the exclusion compared to filing single.
- Whether depreciation was ever claimed — former rental properties owe depreciation recapture separately, taxed at up to 25% federally.

Do you pay capital gains tax if you sell your house and buy another one in Ohio?
Yes, potentially — buying a replacement home doesn't shield you from capital gains tax the way it did before 1997. Today, the tax owed on a home sale in Ohio depends only on your gain, your exclusion eligibility, and your income, regardless of whether you reinvest the proceeds into a new house.
How is capital gains tax calculated on an inherited home in Ohio?
Inherited homes get a stepped-up basis equal to the property's fair market value on the date of death, which usually erases most of the gain the original owner had built up over years of ownership. If you're weighing whether to sell or rent out an inherited property, the process for selling an inherited home in Cincinnati covers the basis and timing questions that come up most.
Is there a way to avoid capital gains tax on a home sale in Ohio?
For most sellers, the Section 121 exclusion already avoids the tax entirely — $250,000 single or $500,000 married filing jointly covers the full gain on the majority of primary-residence sales in Southern Ohio. Investment property owners without exclusion eligibility can defer the tax further through a 1031 exchange, though that only applies to property held for business or investment use, not a primary home.
FAQ
What is the capital gains tax rate on a home sale in Ohio in 2026?
The federal rate is 0%, 15%, or 20% depending on your income, and Ohio adds its own income tax on top, topping out near 3.5% in 2026. Most primary-residence sellers pay neither rate because the $250,000/$500,000 exclusion erases the gain first.
Do I have to pay capital gains tax if I sell my home for a loss?
No — a loss on the sale of a personal residence isn't taxable and also isn't deductible against other income. Capital gains tax only applies when your sale price exceeds your adjusted basis after selling costs.
How much capital gains tax will I pay if I don't qualify for the exclusion?
Your full gain gets taxed at your federal long-term capital gains rate (0%, 15%, or 20%) plus Ohio's income tax rate of up to 3.5%. Not qualifying usually means you didn't meet the two-of-five-year ownership and residency test.
Does Ohio have a separate real estate transfer tax besides capital gains tax?
Yes — Ohio charges a real estate conveyance fee at closing, which is separate from and unrelated to capital gains tax. The conveyance fee reduces your net proceeds; it doesn't factor into your taxable gain calculation.
Can I deduct home improvements from capital gains tax on a home sale?
Yes — documented capital improvements like a new roof, an addition, or a major system replacement raise your cost basis, which directly lowers your taxable gain. Routine repairs and maintenance don't count, only improvements that add value or extend the home's life.
What happens if I sell a rental property in Ohio instead of my primary home?
Rental property doesn't qualify for the Section 121 exclusion unless you also lived in it as your primary residence for two of the last five years. You'll also owe depreciation recapture, taxed federally at up to 25% on the depreciation you claimed while renting it out.
How does the Net Investment Income Tax affect an Ohio home sale?
The 3.8% Net Investment Income Tax applies to capital gains when your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). It stacks on top of your federal capital gains rate and Ohio's income tax, so high earners can see a combined rate well above 20%.
One last thing
The most common mistake sellers make isn't misunderstanding the tax rate — it's forgetting to track capital improvements. A roof replacement, a finished basement, or a new HVAC system can each add tens of thousands of dollars to your cost basis, and without receipts or contractor invoices, that documentation disappears the moment you need it. Pull those records together before you list, not after the sale closes.
