Do You Pay Capital Gains Tax When You Sell a Home in Killeen, TX?
Most Killeen sellers don’t owe a dime. Texas has no state income tax, and the federal home-sale exclusion lets you keep up to $250,000 of profit tax-free if you’re single, or up to $500,000 if you’re married and filing jointly — as long as you owned and lived in the home for at least 2 of the last 5 years. You only owe federal capital gains tax on profit above that line. And if you’re active-duty military on PCS orders, you can pause that 5-year clock for up to 10 years.

Here’s what the data says. In a Killeen market with a median sale price around $225,000 and prices down roughly 9.5% year over year, very few sellers are sitting on a gain large enough to trigger a capital gains bill. But “most people don’t owe it” is not the same as “you don’t owe it.” The only way to know your number is to run your actual cost basis against your actual sale price — and that’s the math worth doing before you list.
Let me show you my logic: how it works, who actually pays, and the one rule almost every military seller near Fort Hood gets wrong.
The home-sale exclusion: why most Killeen sellers owe nothing
The federal capital gain on your home is not your sale price. It’s your profit — what you sell for, minus what the IRS calls your cost basis.
Your cost basis is bigger than most people think. It includes:
- What you originally paid for the home
- Capital improvements you made over the years — a new roof, an added bathroom, a replaced HVAC system, fencing, a covered patio
- Your selling costs — agent commissions, title fees, and other closing costs
Add those up, subtract from your sale price, and that’s your gain. Then the exclusion goes to work.
If you owned and used the home as your primary residence for at least 24 months out of the 5 years before the sale, you can exclude:
- $250,000 of gain if you file single
- $500,000 of gain if you’re married filing jointly
Here’s a real-world Killeen scenario. Say you bought in 2019 for $180,000, put $20,000 into improvements, and sell today for $250,000 with about $18,000 in selling costs. Your gain is roughly $250,000 minus $180,000 minus $20,000 minus $18,000 — about $32,000. That’s well under the $250,000 exclusion, so your federal capital gains tax is zero.
That’s the situation for the large majority of sellers in Killeen, Harker Heights, and Copperas Cove. The equity is real, but it rarely clears a quarter-million dollars of profit on a single home.
Military PCS sellers: how to pause the clock near Fort Hood
This is the rule that protects Fort Hood families — and the one most sellers don’t know exists.
Normally you have to live in the home 2 of the last 5 years to qualify for the exclusion. But if you or your spouse are on qualified official extended duty in the uniformed services, and you receive PCS orders to a station more than 50 miles away, you can suspend that 5-year test period for up to 10 additional years.
In plain terms: you can move for orders, rent the house out for years, and still come back and claim the exclusion when you sell — as long as you hit the 2-year residency requirement at some point inside that extended window. It effectively stretches your 5-year clock to as long as 15 years.
This is exactly the kind of decision I walk military clients through before they choose to sell or rent after orders drop. The exclusion can be a major reason it makes sense to hold a home a little longer — or a reason to sell now while the benefit is locked in. It depends on your timeline, your basis, and what the rental math looks like. The numbers behind that choice are the same ones in my Fort Hood PCS seller’s playbook.
One honest qualifier: the suspension is an election with specific rules, and it interacts with depreciation if you rent the home out. That’s a conversation for your tax professional, not a blog post. I’ll help you understand how it affects your sell-or-rent decision; your CPA confirms the filing.
When you actually might owe — and how to lower the bill
A smaller group of sellers does cross the line. You’re more likely to owe federal capital gains tax if:
- You’ve owned a long-time home with deep appreciation and your gain exceeds $250,000 (single) or $500,000 (married)
- The property was an investment or rental, not your primary residence — different rules and depreciation recapture apply
- You owned the home less than a year, which makes the gain short-term and taxes it as ordinary income
- You’ve already used the exclusion on another home sale in the past two years
For long-term gains above the exclusion, federal rates are 0%, 15%, or 20% depending on your taxable income — Texas adds nothing on top.
If you think you might owe, here’s how you protect your bottom line:
- Document every improvement. Receipts for the roof, the HVAC, the addition — each one raises your basis and lowers your taxable gain.
- Count your selling costs. Commissions and closing costs come off the gain too.
- Mind the 2-year timing. If you’re a month or two short of the residency requirement, the difference can be thousands of dollars.
- Loop in a CPA early. The right basis calculation, done before you list, is the cheapest tax planning there is.
Your specific number depends on your purchase price, your improvements, your filing status, and your timeline — that’s where running the real math with someone who knows this market comes in. It’s the same lens I use on every line item in your net proceeds breakdown and your true cost to sell.
Frequently Asked Questions
Does Texas have a state capital gains tax on home sales?
No. Texas has no state income tax, so there’s no separate state capital gains tax. Any capital gains tax on a home sale is federal only, and most sellers avoid even that through the home-sale exclusion.
How much profit can I make before I owe capital gains tax?
You can exclude up to $250,000 of gain if you file single, or $500,000 if you’re married filing jointly, as long as you owned and lived in the home for at least 2 of the last 5 years. You only owe federal tax on profit above that amount.
I got PCS orders from Fort Hood. Do I lose the exclusion if I rent my house out?
Not necessarily. Active-duty members on qualified extended duty can suspend the 5-year residency test for up to 10 years, which can stretch your eligibility window to as long as 15 years. Renting the home does add depreciation rules, so confirm the details with a tax professional.
Is my home sale profit the same as my sale price?
No. Your taxable gain is your sale price minus your cost basis — what you paid, plus capital improvements, plus selling costs like commissions and title fees. The gain is almost always far smaller than the sale price.
Do I have to report the sale if I don’t owe any tax?
Sometimes. If you receive a Form 1099-S at closing, the sale generally needs to be reported even when the full gain is excluded. Your tax preparer can confirm what your specific closing requires.
Most Killeen sellers walk away from closing owing no capital gains tax at all — but “most” isn’t “all,” and the difference comes down to your basis, your timeline, and, for military families, whether you’ve used the PCS suspension correctly. The number that matters is what you actually keep at closing, not what the sign out front says.
