The Texas homestead exemption, explained

If you own your home and live in it as your primary residence, the Texas homestead exemption is the single easiest tax break available to you. It costs nothing to claim, it does not require a protest, and it lowers your school district taxes on that home. Yet every year thousands of eligible homeowners skip it.

This guide covers what the exemption does, how the appraisal cap that comes with it changes your property tax picture, and how all of this relates to protesting your assessed value. It is general information, not advice on your specific situation.

What the exemption removes

The big number is on your school district taxes. Since the 2023 legislative package (approved by voters as Proposition 4 in November 2023), the general residence homestead exemption removes $100,000 of your home's assessed value from school district taxation. On a $500,000 home, that is a fifth of the value simply not subject to the school tax rate, which is usually the largest single rate on your bill.

The exemption applies only to your residence homestead: the home you own and live in as your primary residence. Vacation homes and rentals do not qualify for the general exemption.

Additional protections exist for homeowners who are 65 or older or living with a disability, including tax ceilings. If that describes you or a spouse, it is worth a call to your appraisal district to see exactly what you qualify for.

How to claim it

You claim the exemption through your county appraisal district. The district's website has the application, and there is no fee to file. If you bought a home recently, check whether the exemption is already in place: it sometimes carries over, but do not assume. A quick search of your account on the appraisal district's website shows your current exemptions.

If an exemption was on the home when you bought it, watch your mail. Texas appraisers send removal notices when ownership changes, and re-applying is on you.

The 10% cap most homeowners have never heard of

Here is the part that surprises people. Once you have the homestead exemption, Tax Code §23.23 limits how fast your *appraised* value can grow: no more than 10% per year, plus the value of any new improvements.

The cap creates a gap. In fast-appreciating neighborhoods, your capped value can sit far below what the home would actually sell for. The district tracks both numbers, the market value and the capped value, and your taxes are calculated from the capped one.

Two consequences follow.

First, the cap is a reason to hold the exemption year after year. It only protects you while it is in place, and consecutive years of the exemption are what keep the cap running.

Second, the cap changes what a protest is worth. If your capped value sits at $400,000 while the market value shows $550,000, a protest that wins a market-value reduction to $520,000 may not change your bill at all, because your capped value never got there. This is a common trap for homeowners who protest without checking which number is driving their taxes.

Exemption vs protest: different tools

People often ask whether filing the homestead exemption hurts their chances in a protest. It does not. The exemption reduces the taxable value for school taxes. A protest contests the appraised value itself. They stack: you want the exemption in place regardless of what happens with your value.

If anything, the exemption gives your protest more room to matter, because the 10% cap means your taxable value has room to grow toward market value in future years. Winning a lower market value now pulls down the ceiling that your capped value climbs toward.

One more exemption-adjacent note: starting in 2024, some non-homestead properties valued at $5 million or less receive an automatic 20% limit on appraised value increases under the "circuit breaker" program, with no application required. That program is currently authorized for the 2024 through 2026 tax years. If you own qualifying non-homestead property and did not receive the limitation, that is itself a protestable issue.

The practical order of operations

1. Confirm your homestead exemption is in place. File with your appraisal district if it is not.
2. Read your Notice of Appraised Value when it arrives in spring and check which value is driving your taxes: the market value or the capped value.
3. If your capped value is the one being taxed and it still feels high relative to similar homes, that is an unequal appraisal argument, not a market-value argument.
4. If the market value itself is inflated relative to what the home would sell for, a protest on comparable sales is the tool.
