What is a property tax appeal?

A property tax appeal (also called a protest) is a formal process where you challenge your county appraisal district's assessed value of your home. In Texas, you file a protest with your county's Appraisal Review Board (ARB), present evidence that your home is overvalued, and the ARB issues a ruling.

In Texas, the deadline to file a property tax protest is May 15, 2026 (or 30 days after your appraisal notice is mailed, whichever is later). There are no extensions.

How much can I save by appealing my property taxes?

Texas homeowners who appeal save an average of $774 per year. Success rates range from 80-91% when homeowners bring comparable sales evidence.
