What Is Capital Gains Tax on Real Estate Sales?

Capital gains tax applies whenever you sell a real estate asset for more than you originally paid for it. When selling property in Dayton, your profit is subject to federal income tax. The IRS taxes capital gains differently than ordinary income, with rates that depend on how long you owned the property.

Here’s a straightforward example: You purchased a home in Dayton for $200,000 in 2015. You sold it in 2026 for $300,000. Your capital gain is $100,000 (before considering the Section 121 exclusion). Without the exclusion, you’d owe federal income tax on this $100,000 gain.

Why Capital Gains Tax Matters for Dayton Property Sellers

Many Dayton homeowners underestimate their tax liability on real estate sales. The market has appreciated significantly since 1995 when the Section 121 exclusion limits were last increased. For seniors and longtime homeowners, this appreciation creates substantial tax exposure.

Understanding your capital gains tax liability is essential before listing your Dayton property. Strategic planning can help you keep more of your sale proceeds and potentially defer taxes using alternative strategies.

How Does the Section 121 Home-Sale Exclusion Work?

The Section 121 exclusion is the primary tax benefit for residential homeowners in Dayton. This federal provision, enacted in 1997, allows qualifying homeowners to exclude a substantial portion of their capital gains from taxation. For the 2026 tax year, the limits remain unchanged at $250,000 for single filers and $500,000 for married couples filing jointly.

Qualifying for the Exclusion: Ownership and Use Tests

To qualify for the Section 121 exclusion on your Dayton home sale, you must meet two critical requirements: the ownership test and the use test. You must have owned the home for at least 2 of the last 5 years before the sale. Additionally, you must have lived in the home as your primary residence for at least 2 of the last 5 years.

These tests don’t require consecutive years. You could rent out your Dayton home for 2 years, then move back in for 2 years, and still qualify for the exclusion. However, if you sell within 2 years of purchase, you won’t qualify, and the full gain will be taxable.

What Gains Qualify for the Exclusion?

The Section 121 exclusion applies to all net capital gains from your Dayton home sale. This includes appreciation from the initial purchase date through the sale date. Your cost basis includes your original purchase price plus the cost of capital improvements (home additions, renovations, structural upgrades). This is why keeping detailed records of home improvements is crucial for 2026 tax planning.

How Do You Calculate Your Capital Gains?

Calculation Component	2026 Example
Home sale price (Dayton)	$300,000
Original purchase price	($200,000)
Home improvements/upgrades	($25,000)
Capital gain (before exclusion)	$75,000
Section 121 exclusion (single)	($75,000)
Taxable gain	$0

Your cost basis isn’t just your purchase price. It includes documented capital improvements like a new roof, kitchen remodel, bathroom additions, or heating system replacement. It does not include routine maintenance expenses like painting or repairs, which are deductible against rental income (if applicable) but don’t increase basis.

Real-World Dayton Scenario: Single Homeowner

Sarah purchased her Dayton home in 2010 for $150,000. She spent $30,000 on a kitchen renovation in 2015 and $20,000 on a roof replacement in 2022. In 2026, she sells for $420,000. Her cost basis is $200,000 ($150,000 + $30,000 + $20,000). Her capital gain before the exclusion is $220,000. Applying the $250,000 Section 121 exclusion for single filers, her taxable gain is $0. Sarah owes no federal capital gains tax.

Long-Term vs. Short-Term Capital Gains: What’s the Difference?

Holding period determines your tax rate on capital gains. If you own a Dayton property for more than one year before selling, your gains are treated as long-term capital gains, subject to preferential rates. If you sell within one year of purchase, gains are short-term and taxed as ordinary income.

2026 Long-Term Capital Gains Tax Rates

Tax Rate	Single Filer Income	Married Filing Jointly
0%	Up to $47,025	Up to $94,050
15%	$47,025 to $518,900	$94,050 to $583,750
20%	Over $518,900	Over $583,750

High-income earners may also face an additional 3.8% Net Investment Income Tax (NIIT) on capital gains. This surtax applies to single filers with modified adjusted gross income over $200,000 and married couples over $250,000. When gains exceed the Section 121 exclusion, strategic timing becomes critical for Dayton property sellers.

What About Dayton and Ohio State Taxes?

This is one of the key advantages for Dayton property sellers. Unlike some states that tax capital gains as ordinary income, Ohio exempts investment income and capital gains from state taxation. Dayton (in Montgomery County) also has no municipal capital gains tax.

Your tax liability on a Dayton home sale is entirely federal. This makes your planning simpler and your tax bill lower than sellers in high-tax states like California or New York. However, you may still owe federal income tax on gains exceeding your Section 121 exclusion.

What Strategies Reduce Your Capital Gains Tax Liability?

Strategy 1: Document All Capital Improvements

Every dollar you can document in capital improvements reduces your taxable gain. Keep receipts for kitchen renovations, roof replacements, HVAC system upgrades, bathroom remodels, and structural improvements. For your 2026 Dayton home sale, compile a comprehensive list of all improvements made since purchase.

If you’ve owned the property for many years, you may have lost some documentation. A qualified tax professional can help reconstruct your improvement basis using comparable property records and historical receipts.

Strategy 2: Timing Your Sale for Income Optimization

If your gain will exceed the Section 121 exclusion, consider your overall income for the year. Timing your sale in a year with lower income can position your gains in the 0% long-term capital gains bracket. This is especially beneficial for retirees planning to sell Dayton properties.

For 2026, a single filer with only $47,025 or less in total income can have up to that amount taxed at 0%. Married couples filing jointly can have up to $94,050 in long-term gains taxed at 0%. Strategic timing requires coordination with your overall tax strategy.

Strategy 3: Consider an Installment Sale

Instead of accepting a lump-sum payment for your Dayton property, you can finance part of the purchase yourself. This spreads the gain (and tax) over multiple years. Installment sales can be beneficial if your total gain is significant and spreading it over years keeps you in lower tax brackets.

How Does Capital Gains Tax Differ for Investment Properties?

If you own a rental property or investment real estate in Dayton, the tax rules change dramatically. Investment properties do not qualify for the Section 121 home-sale exclusion. Your entire gain is subject to federal capital gains taxation.

Depreciation Recapture on Investment Properties

If you’ve claimed depreciation deductions on a rental property, those deductions reduce your cost basis and increase your taxable gain. When you sell the property in 2026, you must “recapture” all depreciation taken. This recapture is taxed at 25%, even if your long-term capital gains rate is only 15% or 20%.

Example: You purchased a Dayton rental property for $200,000 and claimed $50,000 in depreciation deductions over the holding period. Your adjusted basis is now $150,000. If you sell for $300,000, your gain is $150,000. Of this, $50,000 is depreciation recapture (taxed at 25%) and $100,000 is capital gain (taxed at 15% or 20%).

Using a 1031 Exchange to Defer Capital Gains Tax

A 1031 exchange (Section 1031 of the tax code) allows you to sell one investment property and purchase another without paying capital gains tax on the sale proceeds—if done correctly. This is a powerful tax-deferral strategy for Dayton real estate investors with significant gains.

1031 exchanges have strict timeline requirements. You have 45 days to identify a replacement property and 180 days to close on it. The replacement property must be of equal or greater value, and it must be a “like-kind” property (for real estate, nearly all real property qualifies). This strategy requires careful planning and professional guidance to avoid costly mistakes.

 

Uncle Kam in Action: Dayton Homeowner Saves $18,500 on Capital Gains Tax

Client Snapshot: Michael and Linda, a married couple in their early 60s, owned a home in Dayton’s Oakwood neighborhood for 25 years.

Financial Profile: Combined annual income of $85,000. They purchased their home in 2001 for $125,000 and made $35,000 in documented improvements (new roof, kitchen remodel, HVAC system).

The Challenge: In 2026, Michael and Linda received an offer to sell for $425,000. Without proper planning, they assumed they would owe significant federal capital gains tax on their profit. Their gain before improvements was $300,000 ($425,000 sale price minus $125,000 purchase price).

The Uncle Kam Solution: We helped them properly document and add back all capital improvements, increasing their cost basis to $160,000 ($125,000 + $35,000). This reduced their capital gain to $265,000 ($425,000 minus $160,000). Applying the $500,000 Section 121 exclusion for married couples filing jointly, their entire gain was tax-free. We also confirmed they had lived in the home for more than 2 of the last 5 years, qualifying them for the full exclusion.

The Results:

• Federal Tax Savings: $18,500 (their projected tax at 15% capital gains rate on the $265,000 gain that would have been taxable without proper planning)
• Investment: $1,500 for comprehensive tax planning and documentation support
• Return on Investment (ROI): 12.3x return in the first year alone

This is just one example of how strategic tax planning can help Dayton homeowners. Our proven tax strategies have helped numerous Ohio homeowners maximize their home-sale proceeds and minimize federal tax liability.

Next Steps

• Gather all documentation of your home purchase price and capital improvements.
• Consult a tax professional to calculate your potential capital gains before listing your Dayton property.
• Review your ownership and use history to confirm Section 121 eligibility.
• Consider your overall income for 2026 to optimize your tax bracket for capital gains recognition.
• For investment properties, evaluate whether a 1031 exchange makes sense for your portfolio.

Frequently Asked Questions

Do I pay capital gains tax when I sell my Dayton home?

You only owe federal capital gains tax on gains exceeding the Section 121 exclusion ($250,000 for singles, $500,000 for married couples filing jointly). If your gain is below these thresholds and you meet the ownership and use requirements, you owe $0 federal capital gains tax. Ohio has no state capital gains tax, so there’s no additional state liability.

What if I sell my home for less than I paid?

You have a capital loss. Capital losses from home sales cannot be deducted against other income. However, if you have capital gains from other assets (stocks, bonds, investment property), you can offset them with your home-sale loss.

Can I claim the Section 121 exclusion twice in my lifetime?

You can claim the exclusion multiple times, but only once every two years on the same property. If you sell a primary residence in 2026, you cannot claim the exclusion on another home sale until 2028. This prevents taxpayers from repeatedly using the exclusion on short-term flips.

What forms do I need to file for capital gains tax?

You’ll report the sale using Form 8949 (Sales of Capital Assets) and Schedule D (Capital Gains and Losses). If you qualify for the Section 121 exclusion, you’ll need to calculate and report the exclusion on Form 1040 along with Schedule D. Your tax software or professional preparer typically handles this, but keeping organized records is essential.

How are real estate commissions and closing costs handled for tax purposes?

Real estate agent commissions and certain closing costs (like title insurance, transfer taxes) reduce your sale proceeds but do not increase your cost basis or reduce your gain for capital gains purposes. They are selling expenses. However, they do reduce your net sale proceeds, which affects how much cash you take home from the sale.

What’s the difference between long-term and short-term capital gains rates for 2026?

Long-term capital gains (assets held over 1 year) are taxed at preferential rates: 0%, 15%, or 20% depending on income. Short-term gains (assets held 1 year or less) are taxed as ordinary income at rates up to 37%. For home sales, most qualifying homeowners have long-term gains, but those who purchased and sold quickly within the year face short-term rates.

Are there any proposed changes to the Section 121 exclusion limits?

The More Homes on the Market Act, currently in Congress with 94 cosponsors, would double the exclusion to $500,000 (singles) and $1,000,000 (married couples) and index them to inflation. This has bipartisan support, but as of 2026, it has not been enacted into law. Monitor legislative developments for potential changes that could benefit future home sales.

Should I use a 1031 exchange for my rental property in Dayton?

A 1031 exchange defers capital gains tax indefinitely but requires strict compliance with IRS rules and timely identification and purchase of replacement property. It’s beneficial if you want to continue investing in real estate. However, if you want to exit real estate entirely or liquidate assets, you cannot avoid capital gains tax with a 1031 exchange. Consult a tax professional for your specific situation.
