Appeal your property tax assessment and win the reduction
A formal protest filed with your county appraisal review board before its deadline — the assessor's property card corrected for square-footage and room-count errors, three to five comparable sales pulled from before the statutory valuation date, an adjustment grid built, defect photos attached, and a five-minute hearing presentation rehearsed.

Who it's for
U.S. homeowners who received an assessment notice valuing their home above fair market value or above comparable neighborhood assessments, and who want to keep the savings instead of paying a contingency firm 25 to 50 percent of it. Best fit for single-family homeowners; also usable by owners of small condos and townhomes with scaled-down evidence requirements.
About this playbook
Appeal your property tax assessment and win the reduction walks you from the day the notice of appraised value lands in your mailbox to the moment the corrected value shows up on your next tax bill. You will decode the notice, find your county's real deadline and rules, pull comparable sales that closed before the statutory valuation date, and build an adjustment grid the appraisal review board will accept. Along the way you meet the assessor informally — where many protests are settled — and only file a formal protest when the numbers justify it. The playbook ends with a rehearsed five-minute hearing presentation and the written decision in hand. It covers value and unequal-appraisal protests for owner-occupied homes and does not cover agricultural or homestead exemptions, multi-family or commercial property, or lawsuits against the county.

What you need first
A copy of the current notice of appraised value, access to the county appraisal district's online property record, a phone or camera to photograph the home, and the ability to pull comparable sales from the county's public records or a real-estate listing site. Every table and calculation is filled inside the step — no external file is needed.

Common questions
Glossary
- appraisal review board
- A local panel that hears formal property tax protests for a county and issues a written decision on the assessed value. In this guide, the formal protest and its evidence packet are filed with and served on this board, and its written order confirms or corrects the assessment.
- property record card
- The county assessor's working record of a home's characteristics — square footage, room count, year built, lot size and condition grade — that underlies its assessed value. In this guide, the reader requests this card from the assessor's website and checks it line by line against the actual home to find errors that can lower the assessment on their own.
- comparable sales
- Sales of similar nearby homes used as evidence that a home's assessed value is too high. Only arms-length sales — excluding foreclosures, short sales and family transfers — that closed before the statutory valuation date qualify, and the shortlisted ones become the basis of the adjustment grid.
- adjustment grid
- A table that adjusts each comparable sale's price up or down for differences from the subject home, such as size, condition or lot features, using rates tied to paired sales or published cost tables. The median of the adjusted prices across the grid becomes the value argued to the assessor and the appraisal review board.
- informal review
- A meeting with the assessor's office, held before a formal protest hearing, where the property owner presents evidence such as property-card errors and comparable sales in hopes of an agreed value without going before the board. Reaching an agreement here does not remove the need to still file the formal protest by the statutory deadline in counties that require the agreed value to be entered on the roll.
- Comptroller Form 50-132, Property Owner's Notice of Protest
- The Texas form used to file a formal property tax protest with the county appraisal district, naming the value being argued and the grounds — value protest, unequal appraisal, or both — being challenged. Other states use their own equivalent county or state board protest form.
- escrow account
- An account, typically held by a mortgage servicer, that collects funds toward property taxes and pays the tax bill on the owner's behalf. A corrected assessed value from a successful protest applies to the next tax bill, and getting the escrow account to reflect the lower amount requires a separate request to the servicer, on its own timing.
