Missing May 15 doesn’t always mean your protest options are gone, but the path forward depends on which narrow exception applies.
- Texas Tax Code §41.44(b) allows a late protest with “good cause,” but the bar is high and the appraisal review board (ARB) decides case by case
- §41.411 lets you protest later if the appraisal district never sent you the required notice of appraised value
- §25.25(d) can correct a substantial error in your tax appraised value (1/4 overvaluation for homesteads, 1/3 for non-homestead property)
- If no exception applies, your 2026 value is locked, but exemptions, clerical corrections, and next-year prep can still help
In practice, these exceptions almost never apply. They exist on paper for a small set of genuinely extraordinary circumstances, and most homeowners who miss May 15 will not qualify. If you think your situation might be one of the rare ones, act quickly; the window closes when the ARB certifies the appraisal roll, usually by late July.
Understanding the Texas Property Tax Protest Deadline
Texas property tax law runs on a strict calendar. Under Texas Tax Code §41.44, you must file your notice of protest by May 15 or within 30 days after your county appraisal district mailed your Notice of Appraised Value, whichever is later. The mailing date printed on your notice controls the clock. For a full overview of how the protest process works, that timeline is your first stop, and protecting your right to property tax reductions in Texas starts with filing on time.
The deadline matters because it kicks off the only formal channel for challenging your home’s tax appraised value for the current year. Once you file, you get an informal meeting with an appraiser; if that doesn’t resolve things, a formal hearing before the Appraisal Review Board follows.
Most Texas homeowners receive their Notice of Appraised Value in April, giving four to six weeks to file. The question every year is the same: can I still file a property tax protest after the deadline in Texas? The honest answer is almost never. A handful of narrow statutory exceptions exist, but they are rarely available in practice, and most homeowners who miss May 15 will pay the appraisal district’s number for the year. The rest of this guide walks through the few exceptions, why they almost certainly don’t apply to you, and what to do instead.
Can You File a Late Protest in Texas? Three Exceptions That Apply
Before getting into specifics, it’s worth being direct: for the overwhelming majority of homeowners, missing May 15 means there is no path to a protest this year. Texas property tax law treats the deadline as firm, and the appraisal review board (ARB) is not in the business of making exceptions for ordinary life circumstances. Even when homeowners think they have a strong reason, the bar set by the statute and applied by local ARBs is high enough that most late-filing attempts are denied.
Three statutory exceptions do exist, and it’s useful to understand each in case your situation is genuinely one of them. Each requires documentation and ARB approval, and each operates as a narrow safety valve rather than a general second chance to file a late protest in Texas after the May 15 deadline.
Good Cause Under Tax Code §41.44(b)
If you can show “good cause” for missing the deadline, the ARB may grant a hearing per the Texas Comptroller’s guidance on protests. The protest must be filed before the ARB approves the appraisal records, typically around July 20.
Each ARB defines “good cause” on its own and most boards interpret it strictly. Reasons with a realistic chance include serious illness during the protest period, active military deployment without communication access, a death in the immediate family near the deadline, or a natural disaster that prevented filing. Forgetting, being busy, or not understanding the process never qualify.
If you believe you have genuine good cause, file as soon as possible with a written explanation and supporting documents, such as medical records, military orders, or a death certificate.
Failure to Receive Notice Under §41.411
If the appraisal district never sent you the required Notice of Appraised Value, Section 41.411 of the Texas Property Tax Code gives you a longer window. You can file a “protest of failure to give notice” any time before the taxes on your property become delinquent, generally February 1 of the year following the tax year.
To qualify, you must show that the chief appraiser failed to deliver a notice you were entitled to receive. The most common scenario is a recent move where the appraisal district had an outdated mailing address. Evidence might include a closing statement, a USPS change-of-address confirmation, or records showing the notice was sent somewhere you no longer live. You also have to keep your taxes current to preserve this remedy.
Substantial Error Correction Under §25.25(d)
A third path opens when your tax appraised value contains a “substantial error.” Under Section 25.25(d), you can file a motion to correct the appraisal roll if your property was overvalued enough to clear a specific threshold:
- Homestead property: the tax appraised value must exceed the correct value by more than one-fourth (25%)
- Non-homestead property: the tax appraised value must exceed the correct value by more than one-third (33%)
The motion must be filed before your taxes become delinquent. A 10% late-correction penalty applies to the tax savings if granted, and the property cannot have been the subject of a regular protest hearing or settlement that year. §25.25(d) is an extraordinary remedy, so you’ll typically need strong evidence such as a licensed appraisal and adjusted comparable sales.
Older guidance sometimes lists 33% as a blanket threshold. That figure applies only to non-homestead property; for homesteads, the threshold is 25%.
What Happens If You Miss the Deadline With No Exception?
If none of the three exceptions above apply, your tax appraised value is locked for 2026. You’ll pay property taxes based on the value the appraisal district set, with no further administrative remedy for that year. That said, two parts of the tax calculation remain in play: exemptions and clerical corrections.
Filing for available property tax exemptions can substantially reduce your taxable value, and exemption applications follow their own timelines independent of the protest deadline. Proposition 13, approved by Texas voters in November 2025, raised the school district homestead exemption from $100,000 to $140,000, applied retroactively to the 2025 tax year.
Proposition 11 added a $60,000 boost for homeowners 65 or older or disabled, creating a combined $200,000 exemption. Under Senate Bill 1801, counties must also verify homestead exemptions at least once every five years, so respond promptly to any verification request to keep your exemption active.
Common exemptions worth checking on include:
- Homestead exemption: $140,000 off your home’s value for school district taxes, plus additional amounts often available for county and city taxes when the property is your primary residence
- Over-65 or disability exemption: an additional $60,000 off school district taxes, plus a school tax ceiling that limits future increases. You cannot stack the over-65 and disability versions
- Veteran exemptions: partial to full exemptions based on disability rating, with separate provisions for surviving spouses
For the over-65 school tax ceiling, the freeze is set at the lower of the amount paid the year the homeowner turns 65 or the following year.
What Steps Can You Take If You Missed the Texas Property Tax Protest Deadline?
A methodical response can soften the impact of a missed deadline protest in Texas and set up a stronger position for next year.
- Check whether an exception applies. Assess whether your situation fits §41.44(b), §41.411, or §25.25(d). If yes, file before the ARB certifies the appraisal roll.
- Pull up your property record at the appraisal district. Errors in square footage, bedroom count, lot size, year built, or property features are not grounds for a protest, but the CAD can correct them directly at any time, which can reduce your assessed value.
- Apply for any exemption you qualify for but haven’t filed. Exemptions are not automatic. A homestead exemption alone takes $140,000 off your school district taxable value, and Tax Code §11.431 allows retroactive homestead applications up to two years after the delinquency date.
- Handle exemption denials separately. If the appraisal district denied an exemption you believe you qualify for, that’s handled directly with the CAD, not through the protest process.
- Start your evidence file for next year. Gather written contractor estimates for major repairs and track sales of properties truly comparable to yours in size, age, condition, and location. Photos are not evidence for the ARB, but contractor estimates and adjusted comparable sales are.
- Set calendar reminders for the 2027 cycle. Notices typically mail in April, and the protest deadline lands on May 15 unless your notice was mailed late.
How Can You Prepare for Next Year’s Tax Season?
The 2026 window may have closed, but the work behind a strong 2027 protest starts now. Useful evidence falls into two categories. Sales comparables are recent transactions of properties similar to yours in size, age, condition, and location, ideally within a quarter-mile radius and sold within the past 12 months.
Properly adjusted comps are persuasive at ARB hearings; raw numbers from popular real estate websites are not. Repair estimates from licensed contractors carry real weight for significant defects like foundation cracks, roof damage, or HVAC issues. TexasLawHelp’s plain-English guide to property tax protests is a useful primer on what evidence the ARB will consider.
Every homeowner gets a fresh chance every spring. A reduction missed this year can be argued for next year, and a Texas property tax protest filed annually compounds over time. Each reduction lowers the starting point for the next year’s calculation, which is why licensed, local property tax professionals recommend protesting every year, regardless of whether your tax appraised value looks high. The only way to know your value is fair is to put it through the full process.
This holds even when a homestead cap is already holding your taxable value below your tax appraised value. The immediate savings may be limited, but the lower baseline protects future tax bills as taxable value climbs toward tax appraised value year by year.
Frequently Asked Questions
Can I file a late protest in Texas if I just forgot the deadline?
Forgetting alone is not “good cause” under §41.44(b). Routine reasons like being busy or losing track of the date are almost universally rejected. If a more serious circumstance contributed, document it and file as quickly as possible.
What is the deadline to file a §41.411 protest of failure to give notice?
You generally must file before property taxes become delinquent, which is February 1 of the year following the tax year. You must also show the appraisal district never delivered the required notice.
How is “substantial error” defined under §25.25(d)?
For homestead property, the tax appraised value must exceed the correct value by more than 25%. For non-homestead property, the threshold is more than 33%. A 10% late-correction penalty applies if granted.
Does protesting next year erase this year’s overpayment?
No. A 2027 protest can address your 2027 tax appraised value, but it cannot retroactively reduce your 2026 tax bill.
What if my appraisal district has the wrong square footage or bedroom count on file?
These are factual errors, not grounds for a protest. Contact your CAD directly with documentation and request a correction. Many districts fix factual errors at any point in the year.
