What is a property tax appeal?

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

When is the Florida property tax appeal deadline?

Florida property owners have 25 days from the date the TRIM (Truth in Millage) notice is mailed to file a VAB petition (Form DR-486). TRIM notices typically mail mid-August, putting the petition deadline in early-to-mid September. The deadline varies by county and is printed on the TRIM notice itself.

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 several hundred to several thousand dollars per year in Florida (Save Our Homes locks in the savings for 10+ years). 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 $49 for a complete personalized appeal packet you file yourself, or $199-$249 for our done-for-you filing service. Ownwell charges a 25-35% contingency on whatever you save — meaning a $2,000 reduction costs you $500-$700 every year forever. We keep 100% of your savings.
