Selling a Home in Texas: How Capital Gains Actually Work

When a Parker County homeowner sells a house at a healthy profit, the first question is almost always "how much of this does the government take?" The reassuring part of the answer is that Texas takes none of it — capital gains on a home sale are a purely federal issue, and Texas has no state income tax to layer on top. The rest of the answer is that a generous federal exclusion means many home sellers owe nothing federally either. Here is how it actually works, and where people trip up.

First, the Texas part: there is no Texas part

Let's clear this up immediately, because it is the most common worry. Texas has no state personal income tax, and a capital gain on selling your home is a form of income. That means there is no Texas income tax on the gain — none. Any tax question about your home sale is a federal question, handled on your federal return. This is one of the real, concrete advantages of selling a home while living in Texas, and it is worth understanding alongside the rest of the state's tax picture, which we cover in Texas taxes: no income tax, but.

What "capital gain" on a home even means

Your gain is not your sale price, and it is not how much cash you walk away with. It is:

Amount realized (sale price minus selling costs) − your adjusted basis = your gain.

Getting the two ends of that subtraction right is the entire game. Overstate your gain and you may pay tax you did not owe; understate it and you have a problem with the IRS. Most of the mistakes we see are on the basis side.

Basis: the number most sellers get wrong

Your basis usually starts as what you paid for the home. But it does not stay there — it is your adjusted basis that matters, and several things adjust it upward, reducing your taxable gain:

• Capital improvements — a new roof, an addition, a remodeled kitchen, a new HVAC system, adding a deck or a pool. These add to your basis.
• Certain closing costs from when you bought, such as some settlement fees and title costs.
• Selling costs like the real estate commission and certain other closing expenses, which reduce the amount realized.

The critical distinction: improvements add to basis; repairs do not. Replacing the roof is an improvement. Patching a leak is a repair. Over years of ownership, forgotten improvements can add up to tens of thousands of dollars of basis that, if you cannot document them, you simply lose — and that lost basis becomes taxable gain. This is why we tell every homeowner the same thing: keep receipts for every improvement for as long as you own the home. Our guide on how long to keep tax records explains why home records outlive most other paperwork.

The primary-residence exclusion

Here is the rule that spares most home sellers from owing anything. Federal law lets you exclude a large amount of gain on the sale of your main home from tax entirely, with a larger exclusion for married couples filing jointly than for single filers. The exact dollar amounts are set by federal law and can change, so confirm the current figures — but the concept is stable and generous enough that a typical home sale produces no taxable gain at all.

To qualify, you generally have to meet two tests:

• Ownership test — you owned the home for a required period during the years before the sale.
• Use test — the home was your main residence for a required period during that same window.

There is also a limit on how often you can use the exclusion — you cannot claim it on sale after sale in quick succession. And partial exclusions can be available even if you fall short of the full tests, in specific situations like a job-related move or health reasons. These details matter, so confirm the current requirements before assuming you qualify.

When you might actually owe federal tax

Even in Texas, some home sales do produce a taxable gain. Watch for these:

• Gain above the exclusion. If your gain exceeds the amount you can exclude — think a home held for decades in a fast-appreciating area — the excess is taxable at federal capital gains rates.
• It wasn't your primary residence. A rental property, a vacation home, or a house you did not live in long enough does not get the primary-residence exclusion. Rentals bring their own wrinkle, since prior depreciation gets recaptured — see rental property income taxes.
• You didn't meet the ownership or use tests. A quick sale after buying can fall short and expose the gain.

Short-term vs. long-term

If any gain is taxable, how long you owned the home matters. Property held longer than a year is taxed at generally more favorable long-term capital gains rates; held a year or less, it is taxed as ordinary income, which is usually worse. The specific rates and brackets are set federally and adjust, so confirm the current ones.

Keep this straight

• Texas takes nothing — the home-sale gain is federal only.
• Your gain is sale price minus selling costs minus adjusted basis, not your cash proceeds.
• Improvements raise basis and cut your gain; keep the receipts.
• The primary-residence exclusion wipes out the tax for most sellers, but you have to meet the ownership and use tests.
• Rentals, second homes, and very large gains are where tax actually shows up.
