Hamilton County deadlines for 2027

MilestoneHamilton County, 2027
Notices of Appraised Value mailedTypically April through early May 2027
Protest deadline for the 2027 seasonMonday, May 17, 2027, or 30 days after your notice was delivered, whichever is later (Tax Code §41.44). May 15, 2027 falls on a Saturday, so §1.06 moves the statutory date to the next business day.
Informal reviews and ARB hearingsMay through July 2027 in most districts; the ARB must approve the records by July 20 (§41.12)
Late protest if you never received a noticeAllowed under §41.411 until the taxes become delinquent (Feb 1, 2028)
§25.25(d) motion for a substantial error (one-third over value)Before the delinquency date, Jan 31, 2028
§25.25(c) correction of clerical errors or non-existent propertyUp to five prior tax years
Binding arbitration after an ARB order60 days after you receive the order (§41A.03)

Texas law sets one statewide protest deadline, but each district mails on its own schedule. If your notice arrives late in May, the 30-day clock from delivery gives you more time than May 17. Write the printed last day on your calendar the day the notice arrives.

How to file a protest in Hamilton County

  1. Read your Notice of Appraised Value. Hamilton CAD mails notices in April and May. The notice prints your proposed market value, appraised (capped) value, exemptions on file, and the last day to file. That printed date controls.
  2. Pull your record and your neighbors’ records. Confirm living area, year built, and condition on your own account. Then collect the appraised values of similar homes nearby. An unequal-appraisal case under §41.43(b)(3) is built from the district’s own numbers, so you do not need sale prices.
  3. File Comptroller Form 50-132 before the deadline. Download Form 50-132, Notice of Protest. Check both “incorrect appraised (market) value” and “value is unequal compared with other properties.” Submit it online, through the protest link on the district website, by e-mail to [email protected], by mail to P.O. Box 352 Hamilton, TX 76531-0352, or by hand delivery at the district office. Keep proof of the date you filed.
  4. Ask for the district’s evidence. Under Tax Code §41.461 you may request the data the appraiser will use at your hearing. Ask in writing when you file. The district must provide it at least 14 days before the hearing.
  5. Take the informal meeting first. Most reductions happen in an informal review with a staff appraiser, not in front of the board. Bring your comparables table and photos, and know the exact value you are asking for.
  6. Present to the Appraisal Review Board if needed. The ARB hearing runs about 15 minutes. State your requested value, hand over your evidence, and answer questions. You will get a written order; you then have 60 days to seek binding arbitration or 45 days for district court.

Forms you will use. Form 50-132 (Notice of Protest) starts every case. If your record lists improvements that do not exist, add a §25.25 correction motion. If a homestead, over-65, or disabled-veteran exemption is missing, file Form 50-114 at the same time.

Protest volume was up 13% from 2024 to 2025. About 5% of all parcels were protested. Of the cases staff settled informally, 34% ended with a lower value. The informal meeting is where good evidence does most of its work.

Your two legal grounds

Market value (§41.41(a)(1)). The district says your home would sell for more than it would. Evidence: recent sales of similar homes, condition problems, repair bids, and anything that depresses value such as flooding, road noise, or a neglected neighbor.

Unequal appraisal (§41.41(a)(2) and §41.43(b)(3)). The district values your home higher per square foot than a reasonable number of comparable homes, adjusted for size and features. This argument runs on the district’s own appraisal roll, which is public, so it works in non-disclosure Texas without buying sale data. It is the ground TaxStand’s packet is built around. Read the deep dive: What is unequal appraisal in Texas?

Check both boxes on Form 50-132. The ARB must rule on each ground you raise, and the lower result wins.
