7 Homestead Exemption Mistakes That Cost Texans Every Year

Texas voters approved Proposition 13 in November 2025, raising the homestead exemption from $100,000 to $140,000, the fifth increase since 1997, according to the Texas Secretary of State.

None of it lands on your bill automatically.

Every dollar of it, plus a handful of larger exemptions many Texans have never heard of, adds up to serious money many families never claim.

These are the homestead exemption mistakes that cost Texans every year.

Note: This is general information, not legal or tax advice. Exemption rules and dollar amounts are subject to change, so confirm the current details with your county appraisal district.

1. Skipping the Exemption Filing

Texas homeowners who never file for the residence homestead exemption pay full freight on every school tax bill that follows.

The state requires school districts to knock the residence homestead exemption off a homestead’s taxable value, but only for owners who file the paperwork.

You won’t get a reminder from the county when the deadline nears.

Skip that one form, and the county keeps taxing your home at its full appraised value every year until you file it.

Texas also caps how fast a homesteaded property’s appraised value can rise, at 10 percent a year.

That cap never switches on until your exemption is on file.

The application is due April 30, though if you buy mid-year, you can often still claim the exemption for the months you owned the home.

2. Missing the Age 65 Bump

Turning 65 unlocks another break on a Texas homestead, an extra $60,000 off the school district’s taxable value on top of the general exemption.

This bump doesn’t appear on your bill automatically.

You have to file a new application, the same form you used the first time, and check the age 65 or disabled box.

That step is separate.

Many Texans filed once at closing and never touched the form again, so the county keeps billing them full price years after they qualified for less.

An eligible disabled person 65 or older can draw on both the age and disability rules, though not both from the same taxing unit in the same year.

3. Letting Your Tax Ceiling Reset

Texas freezes your school tax bill once you hold the age 65 or disabled exemption.

That dollar ceiling can’t rise for as long as you own the home.

Move to a new home, though, and your frozen ceiling doesn’t follow automatically.

Will the county transfer it for you? Only if you ask first.

You have to ask the old appraisal district for a tax ceiling certificate, then hand it to the new county when filing the fresh application.

Skip that step, and your new home starts over with a new ceiling, usually a higher one.

4. Confusing the Veteran Exemptions

A disabled veteran in Texas has two very different breaks to choose from, and filing for the smaller exemption by mistake costs thousands every year.

A veteran with a 10 to 90 percent disability rating from the U.S. Department of Veterans Affairs (VA) can claim a partial exemption worth $5,000 to $12,000 off any one property they own.

A veteran rated 100 percent disabled, or ruled individually unemployable by the VA, qualifies for something bigger on their home.

Not partial.

All of it.

Some veterans who qualify for the full exemption still file the smaller form out of habit, or because nobody at closing mentioned the difference.

That’s the gap between a few thousand dollars off the tax roll and the entire bill disappearing.

5. Missing the First Responder Break

Texas grants a total property tax exemption to the unmarried surviving spouse of a first responder killed or fatally injured in the line of duty.

The home's entire value comes off the tax roll, not just a chunk of it.

The whole bill disappears.

The exemption only holds as long as the surviving spouse stays unmarried and keeps the home as their main residence, and it takes a filed application to start.

Surviving spouses who assume the county applies this automatically after a line-of-duty death keep paying a bill that shouldn't exist.

6. Losing an Inherited Home's Exemption

An heir inheriting a Texas home without a will runs into extra paperwork before the homestead exemption applies, and skipping it costs families every year.

That happens often with intestacy, when someone dies without a will, or a transfer on death deed passing the home straight to an heir.

An affidavit.

The appraisal district wants an affidavit establishing the heir's ownership interest, plus a copy of the previous owner's death certificate and a recent utility bill in the applicant's name.

Skip any one of those documents, and the exemption sits unfiled while the family keeps paying the unexempted rate on a house that's been theirs for years.

7. Skipping the Local Bonus

Local taxing units can each add a homestead exemption on top of the state's, and many homeowners never check for it.

That check almost never happens.

A local taxing unit can adopt an exemption worth up to 20 percent of a home's appraised value, with a floor of at least $5,000.

That's a local decision, not a state one.

Every taxing unit picks a different rate, so the same house can carry a bigger exemption in one county than a nearly identical house two counties over.

The only way to know is to check with your local appraisal district, since the discount doesn't show up unless you ask.

How the Exemption Got Here

Texas's homestead exemption has risen five times since 1997.

The dollar figure moved from $5,000 to $15,000 that year, then $25,000 in 2015, $40,000 in 2022, $100,000 in 2023, and $140,000 after the vote in November 2025.

Voters decided every jump.

Voters approved the latest increase by a wide margin, continuing a streak with no close calls since 1997.

On a home appraised at $300,000, that $140,000 exemption drops the school tax bill to whatever the county charges on a $160,000 home.

Where the Filing Happens

A homeowner files every one of these exemptions with the same office in Texas, the local county appraisal district, not the Comptroller's office and not the county tax assessor-collector.

One office.

One form.

The Comptroller's office writes the rules and publishes the forms, but each Texas county's appraisal district decides individual applications and mails the notices.

A homeowner who moves within Texas has to file fresh paperwork at the new county's appraisal district every time, even when every exemption they qualify for stays exactly the same.

The appraisal district's website usually lists which exemptions are already on file for a given address, so checking takes less time than many homeowners expect.
