Texas property tax protests are due May 15 each year — or 30 days after your Notice of Appraised Value was mailed, whichever is later. The exact deadline for your property is printed on your notice. Don't wait for the last day to file; appraisal-district portals routinely slow under the load.
Texas Tax Code §41.44 sets the property tax protest deadline as May 15 of the tax year, OR 30 days after the date the appraisal district mailed your Notice of Appraised Value, whichever date is later.
That means two homeowners in the same county may have different deadlines. If your county mailed notices on April 12, your deadline is May 15. If your county mailed notices on April 28, your deadline is May 28. The 30-day extension is automatic — you don't have to ask for it — and it's calculated from the date stamped on your notice, not the postmark and not the date you opened the envelope.
When May 15 falls on a weekend or a state-recognized holiday, the deadline rolls automatically to the next business day.

The Texas property tax protest deadline is May 15, 2026, OR 30 days after your Notice of Appraised Value was mailed — whichever date is later. Your specific deadline is printed on your NOAV. If May 15 falls on a weekend or state holiday, the deadline rolls to the next business day.
Texas Tax Code §41.44 extends your deadline to 30 days after the date the notice was mailed, if that's later than May 15. The mailing date is printed on the notice itself — not the date you received it, and not the postal postmark. So a notice mailed April 28 gives you until May 28, but a notice mailed April 10 gives you the standard May 15 deadline.
Under Texas Tax Code, you may file a protest based on failure of notice if the appraisal district was required to send you a notice but didn't, as long as you file before the property's tax delinquency date and your taxes haven't gone delinquent. Some districts also send a notice only when value changes by at least $1,000 — so the absence of a notice may simply mean your appraised value didn't move materially this year.
Generally, no. Texas Tax Code's deadline is statutory and individual appraisal districts can't unilaterally extend it. The 30-day-after-mailing extension is automatic for any property whose notice was mailed after April 15 — so different homeowners in the same county may have different deadlines depending on when their specific notice went out. Always check your own NOAV.
You generally lose the right to protest the appraisal for that tax year. There are narrow late-protest avenues — Texas Tax Code §25.25(d) allows a motion to correct the appraisal roll if the value exceeds market by more than 25% for residence homesteads (one-third for other properties), and 'good cause' late protests exist but are granted at the appraisal district's discretion and require documented extenuating circumstances. The reliable path is to file by your printed deadline.
April 30 is the standard deadline for most exemption applications, including the residence homestead exemption. The homestead exemption isn't a protest — it's a separate filing — but missing it costs significantly more than missing a protest, since it permanently caps your year-over-year appraised-value increases at 10%. If you've moved into a new home in the last year, apply for homestead well before April 30.
