A residence homestead exemption can reduce the taxable value used by certain taxing units on a qualifying principal residence. It is not a discount applied automatically at closing, and the amount saved is not the same for every Houston-area property.

The key is to file with the appraisal district that serves the property, then verify which exemptions the property’s taxing units actually offer.

What the general homestead exemption does

Texas law requires school districts to provide a general residence homestead exemption. As of this guide’s September 2026 review, the Texas Comptroller lists the school-district exemption at $140,000 of value. Other taxing units may offer additional local-option exemptions, and those local choices can change.

That does not mean every homeowner saves the same dollar amount. The tax effect depends on the home’s appraised and taxable values, the taxing units attached to the address, their rates, and the exemptions each unit provides.

Use the property taxes guide for the larger picture. Homestead is one part of a property tax calculation, not a replacement for reviewing the entire tax profile.

Where to file

You file with the county appraisal district responsible for the property. Greater Houston includes multiple appraisal districts.

Examples include:

If you are unsure which county applies, start with the Texas Comptroller’s local property appraisal and tax directory. A mailing address that says Houston, Katy or another familiar city name is not enough by itself to identify the correct appraisal district.

For example, Katy reaches across more than one county. File based on the parcel’s actual county, not the city name on the envelope.

Who determines eligibility

The local appraisal district’s chief appraiser determines whether a property qualifies. The Texas Comptroller publishes statewide forms and guidance, but it does not approve an individual homeowner’s exemption.

The residence generally needs to be your principal residence and you must meet the statutory ownership and occupancy requirements. Other exemptions may exist for homeowners who are age 65 or older, disabled, veterans or surviving spouses, but each has its own requirements.

Do not pay a third party simply because a letter makes the filing look mandatory or complicated. Start with the appraisal district’s official website and the Comptroller’s official form.

When to file

Texas homestead rules have changed over time, including provisions allowing some homeowners who acquire and occupy a property after January 1 to receive a prorated exemption for part of the year when they qualify.

Because timing depends on the acquisition date, occupancy and the exemption being requested, check the current appraisal-district instructions rather than relying on an old closing checklist.

A practical approach is to put a reminder on your calendar after closing, confirm the appraisal account reflects you as owner, and then use the official filing process as soon as you are eligible.

What you may need

The statewide application is the Comptroller’s Form 50-114, Residence Homestead Exemption Application. Local appraisal districts may offer an online application or mobile process.

Expect the application to require identity, ownership and residence information. Requirements can include matching the property address with identification or providing other documentation allowed by law when the addresses differ.

Use the appraisal district’s current instructions for your situation rather than uploading personal documents to an unofficial site.

Homestead exemption versus the appraisal cap

These are related but different concepts.

The exemption removes qualifying value from taxation for the taxing units that provide it. The residence-homestead appraisal limitation, often called the homestead cap, limits certain year-over-year increases in appraised value after the property qualifies and the statutory conditions are met.

A lower taxable value from an exemption is not the same thing as a cap on appraised-value growth. When reviewing a tax record, look at market value, appraised value, exemptions and taxable value separately.

Buying a home with an existing exemption

Do not assume the seller’s exemption transfers to you permanently. Property tax records can continue showing the prior owner’s exemption for part of the transition period even though your own eligibility must be established.

That is one reason a buyer should not estimate future property taxes by copying the seller’s current tax bill. Review the property as if exemptions and capped values may change after ownership transfers.

The first-time homebuyer guide covers this issue as part of the broader ownership-cost review.

After you file

Keep the confirmation or application record and check the appraisal account later to confirm the exemption appears correctly. Read appraisal notices when they arrive rather than assuming the account is finished forever.

If you move, change ownership, convert the property to another use or otherwise stop meeting the requirements, review the appraisal district’s rules about reporting the change.

The safest workflow is simple: identify the correct appraisal district, use its official application path, keep your documentation, and verify the result on the property account.
