What the Homestead Exemption Actually Does
The Texas homestead exemption is a property tax break for your primary residence. It works two ways, and both matter for your budget.
First, it removes a set dollar amount from the value your school district can tax. For 2026, the general school district homestead exemption is $140,000, raised from $100,000 when voters approved Proposition 13 in November 2025. So if your home is appraised at $450,000, your school taxes are calculated on $310,000 instead. Since the school portion is the biggest slice of an Austin tax bill, that reduction carries real weight.
Second, it caps how fast your taxable value can climb each year, which protects you in a hot market. Both benefits apply only to the home you actually live in, and you have to apply to get them.
Why this matters against Austin's high rates
Texas has no state income tax, so it leans hard on property taxes to fund schools and local government. Combined rates across the metro typically land around 1.7% to 2.3% of value depending on your city, county, and school district. On a $450,000 home, that difference between claiming and not claiming the exemption is not rounding error. If you're still sizing up what those rates mean, our breakdown of the Austin property tax rate walks through the components line by line.
How the 10% Appraisal Cap Works
Once your homestead exemption is in place, Texas Tax Code Section 23.23 limits how much your appraised (taxable) value can rise each year to 10%, no matter how far the market value jumps. The cap does not limit market value itself, only the number you're taxed on.
Each year your taxable value is set at the lesser of the home's full market value, or last year's appraised value plus 10% plus the value of any new improvements you added (a pool, an addition, and so on).
A quick example:
| Year | Market value | Taxable (capped) value |
|---|---|---|
| Prior year | $300,000 | $300,000 |
| This year | $380,000 | $330,000 |
Even though the market value jumped to $380,000, you're taxed on $330,000. The $50,000 gap shows up on your notice as "homestead cap loss." If the market value falls, your taxable value can fall with it. The cap only limits increases.
When the cap starts after you buy
This trips up new buyers. The cap does not apply in your first year. It takes effect on January 1 of the tax year after the first year you qualify for the exemption. In plain terms, your first homestead year is taxed at full market value, and the 10% protection kicks in the following year. That's one more reason to file as soon as you're eligible, so the clock starts running.
Who Qualifies and the Extra Exemptions
To claim a general homestead exemption you must own the home and use it as your principal residence, and you generally must own and occupy it as of January 1 of the tax year. You can only claim one homestead anywhere. There is no income limit for the basic exemption.
On top of the $140,000 general amount, some owners qualify for more:
| Exemption | 2026 amount (school taxes) | Who qualifies |
|---|---|---|
| General homestead | $140,000 | Any qualifying primary-residence owner |
| Age 65 or older | +$60,000 | Owner turns 65 (raised from $10,000 by Prop 11) |
| Disabled person | +$60,000 | Owner meets disability criteria |
A qualifying senior or disabled homeowner shields $200,000 of school-taxable value. Owners 65 and up also get a school tax ceiling that freezes the school portion of their bill. These add-ons are not automatic either, so you file for them separately with proof. If you're buying later in life, our guides to the best 55+ communities near Austin and whether to buy a 55+ community home dig into how these breaks play out.
Cities and counties can also adopt their own local-option homestead exemptions (up to 20% of value), which stack on top of the school benefit but vary by jurisdiction.
How to File in Travis, Williamson, and Hays Counties
You file with your county appraisal district, not the tax office, and it's free. The form is the same statewide (Form 50-114), but you submit it to the district that covers your home.
| County | Appraisal district | Where to file |
|---|---|---|
| Travis | TCAD (traviscad.org) | Online portal, mail, or 850 E. Anderson Ln, Austin |
| Williamson | WCAD (wcad.org) | Online HS Exemption link via Property Search, mail, in person |
| Hays | Hays CAD (hayscad.com) | Online, mail, or in person |
Step by step
- Confirm eligibility. You owned and occupied the home as your primary residence on January 1 of the tax year (new buyers can submit as soon as they own and occupy the home).
- Update your Texas driver's license or state ID so the address matches the property. This is the biggest reason applications get denied.
- Gather your account number or legal description from your deed or closing documents.
- Complete Form 50-114 or the district's online application. List every owner on the deed and note if you're filing late for a prior year.
- Attach a copy of your matching Texas ID.
- Submit online, by mail, or in person, then check your property record later to confirm the exemption shows as active.
Deadlines for new buyers
Treat April 30 as your deadline in all three counties. File by April 30 of the tax year to have the exemption applied for that year. Both TCAD and WCAD open applications on January 1. If you're closing on a new home, our first-time home buyer guide for Austin is a good companion, since filing the exemption is one of the first things to do after you get the keys.
Miss April 30? You can still file late. Texas law generally allows a late homestead application up to two years after the taxes become delinquent, and you may get a refund or correction for prior years once it's approved.
What You Actually Save
Here's a realistic Austin example. Say you buy a $450,000 home in an area with a combined rate near 2.0%, and the school M&O portion runs roughly 0.90%.
Without the exemption, you'd pay school taxes on the full $450,000. With the $140,000 general exemption, the school portion is calculated on $310,000. At a 0.90% school rate, that $140,000 reduction saves about $1,260 a year on the school slice alone, before any local-option city or county exemptions. Add the 10% cap holding your value down in a rising market and the savings compound year after year.
For most Austin buyers, claiming the exemption trims $1,300 to $1,800 a year off the bill. That's money worth folding into your monthly budget, and it's why property taxes belong in your affordability math from the start. Our cost of living guide for Austin shows how taxes stack up against the rest of your expenses. When you're ready to compare specific homes and their tax profiles, start a home search across Austin and factor these numbers into each listing.
Common Mistakes to Avoid
- Assuming it's automatic. Living in the home is not enough; you must apply.
- ID address mismatch. If your license shows an old address, the district can deny you.
- Missing the January 1 rule. If you moved in after January 1, you usually wait until the next tax year.
- Keeping a second homestead. Remove your prior exemption when you move counties, since it does not transfer automatically.
- Ignoring appraisal district mail. Verification or audit letters can remove your exemption if you don't respond.
- Filing under old rules. Use the current form so the 2026 amounts apply correctly.
Frequently Asked Questions
Does the homestead exemption lower my property taxes in Austin?
Yes. It removes $140,000 of value from your school district taxes in 2026, which is the largest single line on most Austin bills. For a typical $450,000 home, that's roughly $1,300 to $1,800 in annual savings depending on your local rates and any city or county exemptions. It also caps how fast your taxable value can grow, saving you more over time.
When should I file after buying a home?
File as soon as you own and occupy the home as your primary residence. New buyers can submit right after closing, and the district will apply the exemption to the year you qualify. The practical deadline is April 30 of the tax year in Travis, Williamson, and Hays counties. Filing early also starts the clock on your 10% appraisal cap.
How much does it cost to file?
Nothing. Applying for a homestead exemption is free through your county appraisal district, whether you file online, by mail, or in person. Be cautious of any company that charges a fee to file it for you, since the application itself carries no cost.
What if I miss the April 30 deadline?
You can still file late. Texas law generally allows a late homestead application up to two years after the taxes for that year become delinquent. You might pay the full bill first and receive a refund or correction once the exemption is approved. Contact your appraisal district to file for the missed year.
Do I have to reapply every year?
No. Once approved, the exemption stays in place as long as you own and occupy the home as your primary residence. You only need to reapply if you move, if the district sends a verification letter, or if you become eligible for an added exemption like the over-65 break. Keep your mailing address current so you don't miss those notices.
