Missed the Texas property-tax protest deadline — what your options are now

Under Tex. Tax Code §41.44(a), a notice of protest is due by May 15 or the 30th day after your notice of appraised value was delivered — whichever is later. That second clause matters more for commercial property than most owners realize. The Tax Code directs appraisal districts to deliver commercial notices by May 1 or as soon thereafter as practicable (§25.19), and in practice many commercial notices go out in late May, June, or even July. Every one of those late notices carries its own 30-day clock, so a large share of commercial parcels have deadlines that fall well after May 15.

So the first step is not a late-protest strategy — it is reading the delivery date on your own notice. If fewer than 30 days have passed since it was delivered, you are not late at all: file the ordinary protest described in how the self-file protest process works, and check the equity ground.

If the deadline has genuinely passed, §41.44(b) directs the ARB to hear a late protest when the owner shows good cause for missing it — but only if the protest is filed before the board approves the appraisal records for the year, which generally happens around mid-July. Two honest caveats. First, the statute does not define good cause; the board weighs the explanation, and there is no formula that assures acceptance. Second, the window is short — by late July this door is typically closed. Owners who think they have a genuine reason (a misdelivered notice, an incapacitating event) file quickly and explain plainly; owners with no particular reason should not count on this route.

The strongest late-season route belongs to owners who never received a notice the district was required to deliver. Tex. Tax Code §41.411 lets the owner protest that failure of delivery itself, and — the part that matters — once the ARB determines the notice was not delivered, §41.411(b) directs it to hear the protest on any permitted ground, including unequal appraisal. This is not a technicality hearing; it reopens the substance, equity test and all (see how the unequal-appraisal protest works).

The fact pattern is more common for commercial property than it sounds. Parcels held in LLCs routinely carry a stale mailing address on the appraisal roll — an old registered agent, a prior manager’s office, an address that predates an acquisition — and the notice goes somewhere no one is reading. The conditions are real, though: the protest generally must be filed before the taxes become delinquent (ordinarily February 1), the owner must actually establish non-delivery, and §41.4115 generally requires paying the amount of taxes not in dispute before the delinquency date to preserve the remedy. Owners who discover a surprise value in October through January are squarely in this route’s season.

Chapter 41 protests are not the Tax Code’s only correction mechanism. Section 25.25 lets owners move to correct the appraisal roll itself: clerical errors and similar defects up to five years back under §25.25(c), and — in the specific case where the appraised value exceeds the correct market value by more than one-third — a §25.25(d) motion filed before delinquency, which carries a 10% penalty trade-off worth understanding before filing. Those motions have materially different standards from a protest, so they get their own guide. And if what landed in your mailbox is a new notice — supplemental or corrected — you may not need any late route at all, because each such notice restarts a fresh 30-day protest window.

Whatever the route, it starts with the same question: does the number look wrong? The free parcel lookup shows a commercial parcel’s assessed $/SF against comparable properties in its submarket — an informational estimate, not an appraisal — so you can see in a minute whether the parcel appears over-assessed before deciding whether a late route is worth pursuing. If it is, the flat-fee evidence packet (from $299) assembles the §41.43(b)(3) comparable-median study that a Chapter 41 protest — on time, good-cause, or §41.411 — is built on. You file it yourself, on your own timeline; the fee is flat and never depends on the result. For what the fee models look like side by side, see flat fee vs. contingency.
