Texas Protest Deadline 2026: May 15 or 30 Days

Texas property tax protest deadline 2026 is May 15 or 30 days after your Notice of Appraised Value is mailed—whichever is later. How to tell which date controls

FAQ

What is the Texas property tax protest deadline for 2026?

May 15, 2026, or 30 days after your Notice of Appraised Value was mailed, whichever is later. If May 15 falls on a weekend or holiday, CADs generally use the next business day—confirm on your notice.

Which date controls if my notice was mailed after mid-April?

Take the later of May 15, 2026 and mail date plus 30 days. If the notice was mailed April 28, thirty days later (May 28) is later than May 15, so May 28 controls for that account.

Does filing with the county tax office meet the protest deadline?

No. File Form 50-132 with your Central Appraisal District. The tax assessor-collector bills after values are set and does not open an ARB protest.

Do I need finished comps on the day I file?

No. Filing Form 50-132 by the later deadline preserves hearing rights. You can keep gathering January 1 sales afterward, but leave time for CAD evidence-upload cutoffs.
