How to Protest Property Taxes in Grayson County

Property valuations in Texas are updated annually, but you do not have to accept the county's appraisal. Under Texas law, you have the right to protest your property tax valuation with the local appraisal district.

Texas Property Tax Protest Process:

  • File Notice of Protest: Submit Texas Comptroller Form 50-132 (Notice of Protest) online via your county's appraisal district portal or by mail.
  • Cite Grounds for Protest: Always check the boxes for "Incorrect appraised (market) value" and "Value is unequal compared to other properties" to protect your legal options.
  • Prepare Comps and Evidence: Get comparable sales data or gather photos showing damage, cracked foundations, or maintenance issues that lower your property's value.
  • Informal Meeting & ARB: Present your evidence at an informal meeting with an appraiser first. If you don't reach an agreement, you can present your case to the formal Appraisal Review Board (ARB).
Texas Protest Deadline: Protests must be filed by May 15th, or 30 days after the date your appraisal notice was mailed, whichever is later.
