How It Works

Three simple steps to lower your property taxes.

1

Calculate

Enter your address. The free check reads the public county record and shows whether a usable comparable-property cohort is available.

2

We Fill It Out

Pay $49 once for the complete Property Assessment Audit. It includes a protest kit with comparable evidence when filing is supported, or an assessment and market-value report when it is not.

3

You Just File It

Open the PDF, review your data, and submit on your county's website before the deadline. Most homeowners file in under 5 minutes. Average successful appeal saves $500+/year, and you can appeal again every year.

The math on a $49 protest kit

This decision compounds

A successful protest resets your assessed value. In Texas it stays lower until the county reassesses, typically 1-3 years, so one $49 protest kit keeps paying you back.

No contingency. No black box.

John Ives · Founder, AppealMyTax

I built AppealMyTax after protesting my own Harris County assessment and finding that the hard part was getting comparable data, not filling in the form. Every comparable we show is a real parcel from your county's public roll. If one looks wrong to you, email me and I will fix it.
