Texas Property Tax Appeal Guide

What This Data Tells Us About Appeals in Texas

In Texas, property tax appeals are filed with the Appraisal Review Board (ARB). The typical window is May 15 or 30 days after receiving the Notice of Appraised Value (whichever is later), with the deadline most commonly falling in May. Filing fees reported for this state are $0 (ARB); $500 for arbitration, and Lincoln Institute research plus state-reported data suggest roughly 57% of appeals result in some reduction when supported by comparable sales or documented errors.

Texas does not cap residential appraisal increases above 10% per year for homesteaded properties. Gather sales of comparable homes from the past 6–12 months. Mass mail protest services are common in Texas but independent representation often yields better results. Appeals are driven by the gap between a parcel's assessed value and its actual market value — the calculator below turns that gap into an annualized dollar figure at your effective tax rate. The strongest evidence is three to five arms-length comparable sales from the past six to twelve months, plus documentation of any factual errors in the assessor's record (square footage, bedroom count, finished-basement status).

Always verify the current rules with your local assessor's office — or a licensed attorney or tax professional — before filing. Source: Texas Comptroller of Public Accounts.
