Texas property tax protest deadline is May 17, 2027 or 30 days from your notice date. Complete county-by-county deadline guide, what happens if you miss it, and how to file fast.
Texas Tax Code § 41.44 establishes the protest deadline as May 15 of the tax year, or 30 days after the appraisal district mailed your Notice of Appraised Value — whichever is later. For most Texas homeowners, the deadline is May 17, 2027. However, if your county appraisal district mailed your notice after April 15, your personal deadline is extended. The date that matters is the mailing date printed on your Notice of Appraised Value — not the date you received it.
Your notice has a mailing date printed on it. If that date is on or before April 15, your deadline is May 17, 2027. If that date is after April 15, add 30 days to the mailing date — that is your deadline.
All major Texas appraisal districts follow the same statutory framework — May 15 or 30 days from notice date, whichever is later.
If you miss your protest deadline, you generally cannot challenge your 2027 assessment. There are very narrow exceptions for clerical errors or mailing address issues, but these are difficult to invoke. The practical answer is: you pay the inflated bill for 2027 and file a protest the following year. This is why filing early matters.
If your deadline is approaching, here is the fastest path: enter your address at TaxAppeal and we check whether a protest will lower your bill. If it will, pay $89 and we prepare Comptroller Form 50-132 with your evidence. In the last days before a deadline there isn't time to mail a printed kit, so we email it to you as a PDF to print, sign and mail. Texas counts a timely postmark, so mail it the same day.
We check first. If an appeal will lower your bill, we mail you a ready-to-sign kit for $89 flat. You sign it and mail it, and you keep 100% of your savings.
TaxAppeal USA is a self-service document-preparation service. We prepare a ready-to-sign appeal kit and mail it to you; you sign it and mail it to the county yourself. In every state we serve, including Florida, we are not property tax consultants, agents, or representatives, we do not provide tax or legal advice, and we do not file appeals or represent customers before any appraisal district, board of assessors, board of equalization, value adjustment board, or review board. Every appeal, protest and petition is prepared for the property owner, signed by the owner, and mailed by the owner in the owner’s name. In Florida your petition is signed by you as the property owner under section 194.011(3), Florida Statutes, and the county’s Value Adjustment Board filing fee is paid by you directly to the county. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
