2026 Texas Property Tax Protest Deadline: May 15 Is Coming
The Texas property tax protest deadline for 2026 is May 15 — or 30 days after your county appraisal district mails your Notice of Appraised Value, whichever is later. Miss it, and you’re locked into whatever value the appraisal district assigned for the entire year. No extensions. No exceptions (with very narrow emergency provisions). No second chances.
If you own commercial property in Texas and your 2026 notice shows an increase — or even if it stayed flat but you think the value is wrong — the clock is ticking right now.
When Exactly Is the 2026 Deadline?
| Scenario | Your Deadline |
|---|---|
| Notice mailed before April 15, 2026 | May 15, 2026 |
| Notice mailed April 20, 2026 | May 20, 2026 (30 days from mailing) |
| Notice mailed May 1, 2026 | May 31, 2026 (30 days from mailing) |
| You didn’t receive a notice | May 15, 2026 (the default still applies) |
The “whichever is later” rule is your friend if you get a late notice. Check the mailing date printed on your Notice of Appraised Value — not the date you received it. That mailing date is what counts.
Most counties in Texas — including Harris, Dallas, Tarrant, Travis, and Bexar — mail notices in mid-to-late April. That means for the majority of commercial property owners, May 15 is the hard deadline.
What You Need to File
Filing a Notice of Protest is not complicated. Under Texas Property Tax Code Section 41.41, your protest just needs to identify the property, name the property owner, and indicate some level of dissatisfaction with the appraisal district’s determination. That’s the legal minimum.
In practice, here’s what you actually do:
- Get your property’s account number from your Notice of Appraised Value or your county appraisal district website
- File a Notice of Protest — most counties offer online filing, which gives you instant confirmation. You can also file by mail or in person.
- Check the boxes for your grounds of protest. For commercial properties, you’ll typically check “Value is over market value” and often “Value is unequal compared with other properties.” Both give you different arguments at the hearing.
That’s it to preserve your rights. You don’t need evidence ready at filing time. You don’t need an attorney. You don’t need a consultant. You just need to file before the deadline.
The evidence gathering and hearing preparation comes later — but if you don’t file, none of that matters.
Why Commercial Owners Can’t Afford to Skip This
The math is brutally simple. Texas has no state income tax, which means local governments lean heavily on property tax. Combined effective tax rates for commercial properties in major Texas metros run between 1.8% and 2.5%.
On a $3 million commercial property at a 2.1% effective rate, you’re paying $63,000 per year in property taxes. If the appraisal district overvalued your property by just 15%, you’re overpaying by $9,450 annually. Over five years of not protesting, that’s $47,250 you’ll never get back.
I’ve seen commercial properties in Dallas County where the assessed value was 25-30% above what the evidence supported. That’s not unusual — it’s what happens when mass appraisal models don’t account for actual property conditions, vacancy rates, or current income performance.
County-by-County Filing Methods
Every Texas county appraisal district accepts protests, but the filing methods vary:
| County | Online Filing | Filing Portal |
|---|---|---|
| Harris (HCAD) | Yes | hcad.org |
| Dallas (DCAD) | Yes | dallascad.org |
| Tarrant (TAD) | Yes | tad.org |
| Travis (TCAD) | Yes | traviscad.org |
| Bexar (BCAD) | Yes | bcad.org |
| Collin (CCAD) | Yes | collincad.org |
Most major counties now have solid online systems. File online if you can — you get instant confirmation and a paper trail. If you mail your protest, use certified mail so you have proof of the filing date.
For smaller counties that may not have online portals, you can download the standard Comptroller’s Form 50-132 and mail or hand-deliver it to your appraisal district.
What Happens After You File
Once your protest is on file, your county appraisal district will schedule you for hearings. The typical timeline:
Informal hearing (April–July): You meet with an appraiser from the district who reviews your evidence and has authority to negotiate a lower value. This is where roughly 65–75% of commercial protests get resolved. Come with comparable sales data, income and expense statements, and documentation of any property condition issues. The appraiser isn’t your adversary — they’re working through a caseload and respond well to organized, data-driven presentations.
ARB hearing (May–August): If the informal hearing doesn’t produce a fair result, your case goes to the Appraisal Review Board — an independent panel of citizens who hear both sides and make a binding determination. You can still negotiate before the panel convenes. For commercial properties above $1 million, having an experienced property tax representative or attorney present your case at the ARB makes a measurable difference.
District court (last resort): If the ARB decision is still unfair, you have 60 days to file a petition in district court. This is rare for most commercial properties but available for high-value disputes where the stakes justify legal expense.
The entire process typically resolves within 60 to 120 days of filing. You don’t need to do anything between filing and your hearing date except prepare your evidence package.
What Evidence Actually Moves Appraisers
Filing is the easy part. Winning the reduction is about evidence. For commercial properties, three types carry the most weight:
Comparable sales: Recent arm’s-length sales of properties similar to yours in class, age, and condition. Not new-construction comps for your 1990s building. Match the vintage and quality tier of your property to the comps.
Income approach analysis: If your property generates rent, your actual net operating income divided by a market-appropriate cap rate often produces a value lower than what the district assessed. Appraisal districts routinely use inflated rent assumptions and compressed cap rates — correcting those to reflect your actual property can be worth 15–25% in reduction.
Equity comparisons: Pull the assessed values of comparable properties in the same district. If the district is assessing similar buildings at $90/SF and yours is at $120/SF, that’s a direct unequal appraisal argument. Texas law requires uniform treatment.
Don’t Wait Until May 14
Every year, commercial property owners scramble to file at the last minute. Online portals slow under volume. Certified mail takes time. One wrong day and you’ve lost the year.
If you’ve already received your 2026 Notice of Appraised Value and you think the number is off, file your protest today. If you haven’t received your notice yet, you can still file based on last year’s assessed value — the appraisal district will update it when the new values post.
The May 15 deadline doesn’t care about your schedule. It’s binary: filed or not filed. An unfiled protest is a missed year of potential savings you can never recover.
