Homestead and over-65 exemptions

Apply through the appraisal district where your home is located. Ask about the general residence homestead exemption and any age-65 or disability exemption that applies to you.

A qualifying over-65 or disabled homeowner may have a school-district tax ceiling. A ceiling limits qualifying taxes; it does not freeze your appraised value. Improvements and other changes can affect it. County, city, and junior-college ceilings depend on local adoption; confirm each taxing unit with the appraisal district.

Your property-tax checklist

Find your property account and review the address, owners, and taxing units.
Ask the appraisal district which homestead exemptions are recorded.
If you are 65 or older, ask about your school tax ceiling and local options.
Check the current application instructions for supporting documents and deadlines.
Use the collector named on your bill for payment balances and due dates.
Keep copies of applications, confirmations, and correspondence.
