DO AUSTIN HOME SELLERS HAVE TO PAY CAPITAL GAINS TAX?

Texas has no state capital gains tax, which means you only need to consider the federal tax when you sell your home. Most Austin sellers who lived in their home for at least two years qualify for a federal exclusion of up to $250,000 (single filers) or $500,000 (married couples filing jointly) — meaning your entire gain may be completely tax-free. If your profit exceeds those limits, the overage is taxed at long-term capital gains rates of 0%, 15%, or 20% depending on your income, not at your ordinary income rate.

Capital gains tax is one of the most common concerns I hear from Austin sellers who are thinking about listing. And most of the time, when we actually sit down and run the numbers, the anxiety turns out to be bigger than the actual tax bill — or there's no bill at all.

Here's what you actually need to know before you decide.

Start Here: Texas Has No State Capital Gains Tax

If you moved to Texas from California, New York, or another state with a high income tax, you may be expecting a state-level capital gains hit. You won't get one. Texas has no state income tax, which also means no state capital gains tax. Every dollar of tax exposure on your home sale runs through federal rules only.

That's genuinely good news — and it's one of the financial advantages of owning real estate in Texas that doesn't always get the attention it deserves.

The Federal Exclusion Most Austin Sellers Qualify For

If the home you're selling is (or was) your primary residence, you may be able to exclude a significant chunk of your gain from federal taxes entirely. The limits are:

• Single filers: up to $250,000 of capital gain excluded

• Married filing jointly: up to $500,000 excluded

To qualify, you need to meet two tests:

Ownership test: You've owned the home for at least 24 months out of the last five years.

Use test: You've lived in it as your primary residence for at least 24 months out of the last five years.

The two periods don't need to be continuous or happen at the same time. If you bought a home in 2021, lived in it through 2023, and then rented it out for a year before selling in 2026, you'd still meet both tests.

For most Austin homeowners who've been in their homes for two or more years, this exclusion covers the entire gain. You'd owe nothing on the sale — not to Texas, and not to the IRS.

How to Calculate Your Actual Gain

Your capital gain isn't just the difference between what you paid and what you sell for. The IRS uses something called your adjusted cost basis, and building it correctly can meaningfully reduce your taxable gain — or eliminate it.

Start with your original purchase price. Then add:

• Closing costs you paid when you bought (title fees, origination fees, etc.)

• Capital improvements made during ownership — a new roof, an addition, HVAC replacement, a major kitchen renovation

Routine repairs don't count. Repainting a room, fixing a leaky faucet, patching a fence — those are maintenance, not improvements, and they don't change your basis.

Then, when you sell, your selling costs (agent commissions, title fees, staging expenses, and repairs required by the buyer) reduce your gain further. Here's the math:

Taxable gain = Sale price − selling costs − adjusted cost basis

Example: You bought your South Austin home in 2018 for $340,000. You added $40,000 in renovations. You're selling for $530,000, with $35,000 in selling costs. Your adjusted cost basis is $380,000, and your gain after costs is $115,000. As a single filer, your entire gain is under the $250,000 exclusion — you owe nothing.

That scenario plays out constantly in the $300K–$700K Austin market, especially for sellers who purchased before 2021. Even with the post-peak price correction (Austin median prices fell roughly 20–25% from the May 2022 high of ~$550,000 before stabilizing around $415,000–$445,000 in early 2026), long-time owners in neighborhoods like Zilker, Bouldin Creek, and Central Austin often still have substantial gains. But substantial doesn't always mean taxable — not after the exclusion and selling costs are applied.

When Your Gain Exceeds the Exclusion

Some Austin sellers — particularly long-time owners in appreciating neighborhoods, or anyone who bought before 2015 — may have gains that exceed the $250K or $500K limits. In that case, the excess is taxed at long-term capital gains rates:

Those rates are:

  • 0% — for lower-income taxpayers (taxable income under ~$94,050 for married filers in 2026)

  • 15% — the most common rate for middle-income sellers

  • 20% — for higher-income taxpayers (roughly $583,750+ for married filers)

Note: These are long-term rates, which apply when you've owned the property for more than one year. If you've held the home less than a year, any gain is taxed as ordinary income — which can be significantly higher. That's a scenario worth avoiding if you have any flexibility on timing.

Additionally, high-income sellers may face a 3.8% Net Investment Income Tax (NIIT) on any gain above the exclusion, stacked on top of the capital gains rate. It's worth checking with a tax professional if your income is in the upper brackets.

Special Situations: Inherited Property, Partial Exclusions, and Partial Rental Use

Inherited Austin homes come with a significant tax advantage called the stepped-up basis. When you inherit a property, your cost basis is reset to the home's fair market value on the date of the original owner's death — not what they paid decades ago. If you sell the home promptly at or near that value, your taxable gain is minimal or zero. Texas has no state inheritance tax, and the federal estate tax threshold sits at approximately $15 million in 2026, so most inherited Austin homes won't trigger estate taxes either.

Partial exclusion applies if you've owned and lived in the home for less than two years but are selling due to a qualifying reason — a job relocation, a health issue, or an unforeseen circumstance (divorce, death in the family, multiple births, etc.). In those cases, the IRS allows a proportional exclusion based on how many months you actually lived there relative to the required 24.

Home used partially as a rental requires some additional calculation. If you rented out part of your home or used it as a rental before converting it back to your primary residence, the exclusion only applies to the portion tied to personal use. This also involves depreciation recapture, which is taxed separately at a 25% rate. If this applies to you, get your CPA involved before you list.

One common misconception: 1031 exchanges cannot be used to defer taxes on a primary residence sale. 1031 exchanges are for investment and rental properties only. If you're selling your home — not an investment property — this strategy isn't available to you.

The Bottom Line for Austin Sellers in 2026

The capital gains picture for Austin sellers is more favorable than most people expect. Texas eliminates the state layer entirely. The federal exclusion is generous. And even sellers with gains above the exclusion face preferential long-term rates — not ordinary income rates — on the overage.

Where it gets specific is in the details: your purchase price, your improvement history, your filing status, how long you've owned the home, and your overall income for the year. Those numbers change your outcome materially. The only way to know your real tax exposure is to run it with your CPA — and to go into the sale knowing what you'll actually net.

That's the conversation I have with every seller before we list. It shapes timing, pricing strategy, and whether now is the right moment to move.

Frequently Asked Questions

Do I have to pay capital gains tax when I sell my house in Texas?

Texas does not have a state capital gains tax, so you only need to consider the federal tax. Most primary residence sellers qualify for the Section 121 exclusion — up to $250,000 of gain for single filers and up to $500,000 for married couples filing jointly. If your profit falls within those limits, you owe no federal tax on your home sale gain either.

How do I qualify for the $500,000 home sale exclusion?

To claim the full $500,000 exclusion (married filing jointly), you must meet two tests: you must have owned the home for at least two of the last five years (the ownership test), and you must have used it as your primary residence for at least two of the last five years (the use test). The two periods don't need to be continuous or the same two years. Single filers qualify for up to $250,000 under the same rules.

What if I've only owned my Austin home for one year — do I still pay capital gains?

If you haven't owned and lived in the home for at least two years, you won't qualify for the full exclusion. However, you may still qualify for a partial exclusion if you're selling due to a job relocation, health reason, or other unforeseen circumstance. Any taxable gain on a home held less than a year is taxed as ordinary income — the highest rate — so timing matters significantly.

What counts as my cost basis when calculating capital gains on my Austin home?

Your adjusted cost basis starts with your original purchase price, then adds closing costs you paid when you bought, plus any capital improvements you made during ownership (new roof, addition, major kitchen renovation). It does not include routine repairs. Your taxable gain is your sale price minus selling costs (agent commissions, closing costs) minus your adjusted cost basis.

Is there capital gains tax on an inherited home in Texas?

Inherited property in Texas benefits from a stepped-up basis, meaning your cost basis is reset to the property's fair market value on the date of the original owner's death — not what they originally paid for it. Texas has no state inheritance tax, and the federal estate tax threshold in 2026 is approximately $15 million. Most heirs who sell an inherited Austin home promptly owe little to no capital gains tax.
