Capital Gains Tax When Selling Your Home in Ohio: What Sellers Actually Owe
One of the first questions I hear from Ohio homeowners who are thinking about selling is some version of this: "If I sell for more than I paid, how much of that goes to taxes?" It is a fair question, especially for owners who have been in their homes for many years.
Here is the good news up front: most homeowners who sell their primary residence owe no federal capital gains tax at all, because of a provision in the tax code that lets you exclude a large amount of gain. The catch is that the exclusion has rules. This guide walks through how it works, how to figure your real gain, and what to gather before you list.
Key Takeaways
- The IRS lets you exclude up to $250,000 of gain on the sale of your main home, or up to $500,000 if you file jointly with your spouse (IRS Topic 701).
- To get the full exclusion, you generally must have owned the home and lived in it as your main home for at least 24 months in the 5 years before the sale.
- Your taxable gain is not simply sale price minus purchase price. Capital improvements raise your basis, and selling expenses lower your amount realized.
- Repairs and routine maintenance do not add to your basis, so keeping receipts for real improvements matters.
- Military members on qualified official extended duty can suspend the 5-year test period for up to 10 years (IRS Publication 523).
- Ohio's income tax return starts with your federal adjusted gross income, so gain you exclude federally generally does not show up on your Ohio return either.
- If you receive a Form 1099-S at closing, the IRS says you must report the sale even if the entire gain is excludable.
- I am not a tax advisor or a lawyer. Use this guide to prepare good questions for your CPA, not as a substitute for one.
I'm Amanda Mullins, a REALTOR® with eXp Realty serving Springfield, Dayton, Yellow Springs, Xenia, Fairborn, Beavercreek, and the surrounding 10-county area of Southwest and Central Ohio. Before real estate, I spent 13+ years as an Appraisal Management Director, coordinating valuations and reviewing how homes were measured, compared, and documented. That background taught me that what a home is worth on the market and what the IRS treats as your "basis" are two very different numbers, and the paperwork you keep can change what you owe.
How the Home Sale Exclusion Works
The rule most people are thinking of is Section 121 of the Internal Revenue Code, which the IRS explains in plain language in Publication 523, Selling Your Home. If you qualify, you can exclude up to $250,000 of gain as a single filer, or up to $500,000 if you are married and file a joint return. Gain under that amount is simply not taxed federally.
The Ownership and Use Tests
To qualify for the full exclusion, the IRS looks back over the 5 years ending on the date of sale. During that window you generally need to meet these tests:
- Ownership: you owned the home for at least 24 months.
- Use: you lived in it as your main home for at least 24 months.
- Look-back: you did not exclude gain on another home sale in the 2 years before this one.
For married couples filing jointly, the $500,000 amount generally requires that either spouse meets the ownership test, both spouses meet the use test, and neither has used the exclusion in the prior 2 years. Publication 523 lays out the full details and exceptions.
When You Sell Before 2 Years
Life does not always wait 24 months. If you have to sell early, you may still qualify for a partial exclusion when the main reason for the sale is a work-related relocation, a health-related reason, or certain unforeseeable events listed by the IRS, such as a death in the household, divorce, or job loss. The partial exclusion is prorated, so the timing and the reason both matter.
A Note for Surviving Spouses
As an SRES (Seniors Real Estate Specialist), I often work with homeowners who have recently lost a spouse. According to Publication 523, a surviving spouse who sells within 2 years of the spouse's death, has not remarried at the time of sale, and meets the other requirements may still be able to claim up to $500,000. That 2-year window is easy to miss during a difficult season, so I flag it early and encourage a call with a CPA.
How to Figure Your Actual Gain
This is where my appraisal background comes in handy. A lot of sellers estimate their gain by subtracting their original purchase price from what they think the home will sell for. That shortcut usually overstates the gain, sometimes by a lot.
Step 1: Start With Your Basis
Your basis generally starts with what you paid for the home plus certain purchase costs. If you do not remember your purchase price or date, your county auditor's website usually shows transfer history. In Clark County, for example, the Clark County Auditor's website lets you search by address or parcel.
Step 2: Add Capital Improvements
Improvements that add value, extend the life of the home, or adapt it to new uses increase your basis. Publication 523 gives examples such as additions (bedrooms, bathrooms, decks, garages), new heating and air conditioning systems, a new roof or siding, water heaters, septic systems, and kitchen modernization. Repairs that simply keep the home in good condition, like repainting a room or fixing a leak, generally do not count.
From my appraisal management years: an appraiser and the IRS look at your upgrades through different lenses. An appraiser asks whether the market will pay more for the home because of the improvement. The IRS asks what you spent on qualifying improvements. A $30,000 kitchen remodel might not raise your sale price by $30,000, but if it qualifies, the full cost can still be added to your basis. That is why I tell every seller to hold onto those receipts.
Step 3: Subtract Selling Expenses
Selling expenses, such as real estate commissions, certain title and closing fees, and other costs of the sale, reduce your amount realized. If you want a sense of what sellers typically pay at closing, see my guide on what closing costs sellers pay in Springfield, Ohio.
A Simple Illustration
The numbers below are hypothetical and for illustration only. They are not based on any real client or property.
| Line Item | Shortcut Math | Basis-Adjusted Math |
|---|---|---|
| Sale price | $320,000 | $320,000 |
| Selling expenses | Not counted | Minus $22,000 |
| Amount realized | $320,000 | $298,000 |
| Original purchase price | $140,000 | $140,000 |
| Capital improvements (roof, HVAC, addition) | Not counted | Plus $45,000 |
| Adjusted basis | $140,000 | $185,000 |
| Estimated gain | $180,000 | $113,000 |
| Taxable after $250,000 exclusion (if qualified) | $0 | $0 |
In this example, the seller owes no federal tax either way. The adjustments matter most when a gain is close to or above the exclusion, or when the seller does not qualify for the full exclusion.
Situations Where Sellers Get Surprised
The exclusion covers most primary-home sales, but these are the situations I see raise questions most often across Southwest and Central Ohio.
| Situation | How the Exclusion Generally Applies | What to Ask Your CPA |
|---|---|---|
| Main home, owned and lived in 2+ of last 5 years | Up to $250,000 single or $500,000 joint excluded | Do I need to report the sale if I get a 1099-S? |
| Sold before 24 months | Possible partial exclusion for work, health, or unforeseeable events | Does my reason qualify, and how is it prorated? |
| Military on extended duty away from the home | 5-year test period can be suspended up to 10 years | Do my orders count as qualified official extended duty? |
| Home was a rental or had a home office with depreciation | Depreciation claimed after May 6, 1997 must be recaptured | How much depreciation will be recaptured? |
| Inherited home you never lived in | Main-home exclusion generally does not apply; different basis rules | What is my basis, and do I need a date-of-death valuation? |
| Sale at a loss | A loss on a main home is not deductible | Is there anything else I should document? |
Military Sellers Near Wright-Patterson AFB
Service members who rent out a home near WPAFB while stationed elsewhere could otherwise lose the exclusion. Publication 523 lets members of the uniformed services, Foreign Service, and intelligence community on qualified official extended duty suspend the 5-year test period for up to 10 years. If you are weighing a sale before or after a PCS, my quick sale guide for military families leaving Wright-Patterson AFB covers the timing side.
How Ohio Treats the Sale
Ohio does not have a separate capital gains tax rate. The Ohio IT 1040 begins with your federal adjusted gross income, so a gain you properly exclude federally generally never enters your Ohio calculation. If part of your gain is taxable, it flows into your Ohio income and is taxed at Ohio's regular income tax rates, which the Ohio Department of Taxation publishes each year. If your city has a local income tax, ask your preparer how it treats the sale.
Federal Rates on Any Taxable Gain
If you owned the home for more than 1 year, any gain above your exclusion is generally a long-term capital gain, taxed at 0%, 15%, or 20% depending on your taxable income, according to IRS Topic 409. Higher-income sellers may also face the 3.8% net investment income tax, but the IRS confirms in Topic 559 that it does not apply to the portion of home sale gain you exclude.
A word of caution: please do not make a sell-or-wait decision based on a tax rumor or a social media post. Tax proposals come and go, and only enacted law and IRS guidance count. Run your real numbers with a CPA, and if you are comparing selling now to holding longer, my guide on whether you will regret selling your Springfield home with a low mortgage rate walks through the other side of that math.
What You Should Do Right Now
- Confirm your dates. Write down when you bought the home and the months you lived in it as your main home during the last 5 years.
- Find your purchase records. Pull your closing statement from when you bought, or look up the transfer on the county auditor's site.
- Gather improvement receipts. Roofs, HVAC, additions, kitchens, decks, water heaters, and similar projects. Organize them by year.
- Note anything unusual. Rental periods, a home office, a prior home sale in the last 2 years, military orders, or a recent loss of a spouse.
- Get a realistic sale price estimate. A pricing conversation with a local agent gives you a working number to plug into your gain estimate.
- Meet with a CPA before you list. Bring your dates, records, and price estimate so you can see your likely tax picture ahead of time.
- Keep everything after closing. Save your settlement statement and any Form 1099-S for your tax return.

Frequently Asked Questions
Do I pay capital gains tax when I sell my house in Ohio?
Most Ohio homeowners selling their main home owe no federal capital gains tax because they can exclude up to $250,000 of gain, or $500,000 if married filing jointly, as long as they meet the IRS ownership and use tests. Because Ohio's return starts with federal adjusted gross income, excluded gain generally is not taxed by Ohio either.
How long do I have to live in my home to avoid capital gains tax?
To claim the full exclusion, you generally need to have owned the home and lived in it as your main home for at least 24 months during the 5 years before the sale. The 24 months of use do not have to be consecutive.
What home improvements reduce capital gains when I sell?
Capital improvements that add value or extend the home's life increase your basis, which lowers your gain. IRS Publication 523 lists examples such as additions, new roofs, siding, heating and air conditioning systems, water heaters, and kitchen modernization. Routine repairs and maintenance generally do not count.
Can I get a partial exclusion if I sell before 2 years?
Possibly. The IRS allows a partial exclusion when the main reason for selling early is a work-related relocation, a health-related reason, or certain unforeseeable events. The amount is prorated, so confirm your situation with a tax professional before you list.
Do military members near Wright-Patterson AFB get special rules?
Yes. Members of the uniformed services, Foreign Service, and intelligence community on qualified official extended duty can suspend the 5-year test period for up to 10 years, according to IRS Publication 523. That can help service members who rented out their home while stationed elsewhere still qualify.
Do I have to report the sale if all of my gain is excluded?
If you receive a Form 1099-S, the IRS says you must report the sale even if the gain is fully excludable. You also must report it if you cannot exclude all of your gain. Your tax preparer will use Schedule D and Form 8949 when reporting is required.
Can I deduct a loss if I sell my home for less than I paid?
No. According to IRS Publication 523, a loss on the sale of your main home is not deductible.
Does the exclusion apply to an inherited house I never lived in?
Generally, no, because the exclusion is for your main home. Inherited property follows different basis rules, often tied to the value at the date of death, so talk with a CPA and an estate attorney about your specific situation.
