What is a property tax appeal?

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

When is the Texas property tax appeal deadline?

In Texas, the deadline to file a property tax protest is May 15 each year (or 30 days after your appraisal notice is mailed, whichever is later). The 2026 deadline has passed; the next protest window is April-May 2027.

How much can I save by appealing my property taxes?

Homeowners who appeal save an average of $774 per year in Texas, and you can protest again every year. Success rates range from 80-91% when you bring 3-5 comparable sales as evidence.

What's the difference between AppealMyTax and Ownwell?

AppealMyTax charges a flat $99, one time, for a complete personalized appeal packet you file yourself, or $199-$249 for our done-for-you filing service. You keep 100% of your savings every year. Ownwell keeps a 25-35% contingency on whatever you save and O'Connor keeps about half, meaning a $2,461 reduction costs you roughly $615-$1,230 every year forever. We charge $99 once and keep nothing.
