Will I Owe Capital Gains Tax If I Sell My McKinney Home Now After All the Appreciation Since I Bought It?
Will I owe capital gains tax if I sell my McKinney home now after all the appreciation since I bought it? Most likely not on your primary residence, thanks to a federal exclusion of up to $250,000 (single) or $500,000 (married filing jointly) in profit - but McKinney's steep price gains over the past several years mean it's worth actually running the numbers instead of assuming.
If you bought in Stonebridge Ranch, Craig Ranch, Trinity Falls, or almost anywhere else in Collin County five, seven, or ten years ago, there's a good chance your home has appreciated well beyond what you paid. That's great news for your net worth, but it also raises a legitimate question: at what point does that gain become taxable income? The answer depends on a few specific factors - how long you've owned and lived in the home, whether it's ever been a rental or investment property, how much you've spent on qualifying improvements, and your filing status. For the vast majority of McKinney homeowners selling a primary residence, the federal exclusion covers the gain entirely, meaning no capital gains tax is owed at all. But if your appreciation is unusually large, or if the home hasn't been your primary residence the whole time you've owned it, the math changes. This post walks through how the exclusion actually works, how to estimate your adjusted cost basis, what can push you over the exclusion threshold, and what documentation you'll want pulled together before you list. It's not a substitute for advice from a CPA or tax attorney, but it will give you a realistic sense of where you stand and what questions to ask before you sign a listing agreement.
The Federal Home Sale Exclusion: Your First Line of Defense
The IRS allows most homeowners to exclude up to $250,000 of gain ($500,000 for married couples filing jointly) from the sale of a primary residence, with no tax owed on that amount. To qualify, you generally need to have owned and lived in the home as your primary residence for at least two of the five years before the sale. If you've been in your McKinney home that long, this exclusion likely covers most or all of your appreciation.
How to Estimate Your Actual Gain
Your taxable gain isn't simply sale price minus purchase price. It's your sale price minus your adjusted cost basis, which includes:
- Your original purchase price
- Closing costs from the original purchase
- The cost of qualifying capital improvements (a new roof, a renovated kitchen, an added room - not routine repairs or maintenance)
- Selling costs like agent commissions and title fees, which reduce your net proceeds further
Pull your original closing statement and any receipts for major improvements before you estimate anything. Homeowners who've owned in appreciating pockets of Collin County for a decade or more are sometimes surprised at how much their basis has grown once improvements are factored in - which directly lowers any taxable gain.
When You Might Actually Owe Something
A few situations push people outside the standard exclusion:
Gains Above the Exclusion Cap
If your profit genuinely exceeds $250,000 (or $500,000 for joint filers) after subtracting basis and selling costs, the amount above that threshold is generally subject to capital gains tax. This is becoming more common for longtime owners in higher-appreciation McKinney neighborhoods.
The Home Wasn't Always Your Primary Residence
If you've rented the property out for a period of time - including as a short-term rental in areas like Craig Ranch or Trinity Falls - you may face depreciation recapture on top of any capital gains exposure, and the two-year residency test gets more complicated. If that applies to you, our post on McKinney's short-term rental ordinance is worth a read alongside this one.
You Haven't Met the Two-Year Ownership/Use Test
Selling sooner than two years in usually means no full exclusion, though partial exclusions can apply for qualifying reasons like a job change, health issue, or other unforeseen circumstance.
Why This Matters More in Today's McKinney Market
Appreciation across McKinney and the broader Collin County market has been strong enough over the past several years that some longtime owners are approaching or exceeding the exclusion caps, especially those who bought pre-2015 in established communities. It's also a factor worth weighing if you're deciding between selling now and renting your home out until the market shifts - converting to a rental can affect your exclusion eligibility down the road.
Documentation to Gather Before You List
- Your original settlement/closing statement
- Receipts or invoices for major capital improvements
- Records of any period the home was rented, including approximate dates
- Prior year tax returns if you've claimed home office or rental deductions
The Collin Central Appraisal District can also help confirm assessed value history, though your actual gain calculation should rely on your purchase and improvement records, not appraised value.

Frequently Asked Questions
Do I owe capital gains tax on my McKinney home if I've lived there less than two years?
Possibly, unless you qualify for a partial exclusion due to a job change, health issue, or other IRS-recognized unforeseen circumstance. Full exclusion generally requires two years of ownership and use as your primary residence within the five years before the sale.
Does a home renovation reduce my capital gains tax?
Qualifying capital improvements increase your cost basis, which can lower your taxable gain. Routine repairs and maintenance generally don't count - only improvements that add value or extend the home's life.
What if my McKinney home was a rental before I moved back in?
Rental history can trigger depreciation recapture and may limit your exclusion eligibility even after you move back in. This situation is common enough in Collin County's investment-heavy neighborhoods that it's worth a dedicated conversation with a tax professional before listing.
