Texas property tax answers · Updated June 2026
Is it too late to protest my property taxes in Texas?
The short answer
For the current tax year, usually yes once May 15 passes (Texas Tax Code Section 41.44). Two real exceptions exist: if your notice was mailed late, you get 30 days from the mailing date, and a late correction motion under Section 25.25(d) is possible if your homestead is assessed at least 25 percent above comparable value. Otherwise, the smart move is locking in next year now.
The honest answer first
Texas Tax Code Section 41.44 sets the protest deadline at May 15, or 30 days after your appraisal notice was mailed, whichever is later. Once that passes, you can't file a regular protest for the current year, and no company can file one for you either, whatever their ads imply. If a notice reached you late, count 30 days from the mailing date before you write the year off.
The exception worth checking: Section 25.25(d)
Texas allows a late correction motion under Tax Code Section 25.25(d) when the error is large. For a homestead, your appraised value has to exceed the correct value by more than one-fourth, 25 percent. For non-homestead property the threshold is one-third. The motion can be filed up to January 31, when taxes go delinquent, it carries a 10 percent late-correction penalty on the tax difference, and it's only available if you didn't already protest the property this year.
That 25 percent bar is high, but it's not rare. Our 13-county study of 4.6 million parcel records found about 945,000 over-assessed Texas homes, and the worst cases clear the threshold. The free check shows your exact over-assessment percentage in 30 seconds, so you'll know immediately whether 25.25(d) is on the table for you.
What to do with the months in between
If you don't clear the 25.25(d) bar, the current year is locked, but the work you do now isn't wasted. The same $99 comp report is usable today: it's the real, comp-backed value of your home, the kind of evidence you can hand a buyer, a lender, or an agent if you're selling, refinancing, or fighting a low appraisal. See the valuation report if that's your situation.
And the tax win still happens, just next cycle. Buy the packet now and we watch your county, rebuild your packet with fresh comps the moment next year's values publish, and remind you before the May 15 deadline so you file on time. Texas reassesses every year, so a case that exists today almost always exists next April too. Protests work at very high rates for homeowners who actually file; the whole game is being in the window with evidence ready.
