Texas Property Tax Protest Deadlines

Texas Form 50-132 deadline: May 15, 2026 or 30 days from your CAD notice — whichever is later. Track separate §41.461 and supplemental evidence upload dates on your protest portal.

Texas homeowners must file Form 50-132 before May 15, 2026, or 30 days after your Notice of Appraised Value is mailed — whichever is later. Missing the window usually forfeits your protest for the tax year.

Count from the mailing date on your Notice of Appraised Value when it arrives after April — you may have more than the standard May 15 deadline.

After filing, Central Appraisal Districts publish supplemental evidence and §41.461 exchange deadlines on their protest portals — those dates are separate from the Form 50-132 filing window and are easy to miss during peak April–May volume.

Mark both dates on your calendar: the protest filing deadline on your notice and the evidence-upload cutoff for your account. A timely protest with late evidence often loses at informal review and the ARB.

FAQ

What happens if I miss the deadline?

Late filings are usually rejected for that tax year. Mark your notice mailing date immediately and file before the statutory window closes.

Does mailing date or receipt date count?

Count from the date printed on your official notice — not when you opened it. Confirm current rules with your local appraisal office.

Can I protest and file exemptions in the same year?

Yes. Exemptions and market-value protests are separate filings — fix missing exemptions and protest appraised value if it still exceeds market evidence.
