Frequently asked questions

Plain answers about cost, deadlines and evidence before you protest.

What is a property tax protest?

A property tax protest is your legal right to challenge the appraised value the county places on your home. In Harris County, you file a protest with the Appraisal Review Board (ARB) and present evidence that your home is over-assessed compared to similar properties.

How much does Harris Value cost?

Looking up your property, viewing assessment history, and reviewing appraisal and sales comps is free — no login required. Printable reports may require an email sign-in so you can return to them later.

When is the deadline to protest?

In Harris County, your deadline is May 15 (or 30 days after your notice of appraised value is mailed, whichever is later). You can file online via HCAD's website.

What are comparable properties?

Comparable properties (comps) are nearby homes with similar characteristics — square footage, age, bedrooms, bathrooms, and quality grade. If similar homes are assessed at lower values per square foot, that's evidence your property may be over-assessed.

Do I need a lawyer or tax agent?

No. Many homeowners successfully protest on their own using evidence like what Harris Value provides. Review the official filing instructions and choose representation if you need help with your circumstances.
