Texas Property Tax Protest Guide for 2026

Texas has some of the highest effective property tax rates in the United States — commonly 1.5% to 2.5% of market value — because there is no state income tax. That makes Texas one of the most consequential states in which to protest your assessment. Roughly half of all Texas protests result in some reduction, and homeowners with strong comparable sales evidence win at much higher rates.
Texas Filing Deadline (2026)
The standard deadline to file a Notice of Protest in Texas is May 15, or 30 days after the appraisal district mails your Notice of Appraised Value, whichever is later. Most homeowners receive their notice between mid-April and early May. Missing the deadline forfeits your right to protest the current year’s value — you have to wait an entire year.
You file Form 50-132 (Notice of Protest) with your County Appraisal District (CAD), not with the tax assessor. Texas separates the appraiser (CAD) from the collector (county/city tax office); only the CAD can change your appraised value.
Texas Has Two Powerful Protest Grounds
Texas Property Tax Code §41.41 lists multiple grounds, but two carry most of the weight:
- Excessive market value. The classic protest — you argue the appraised value is higher than what your home would actually sell for. Comparable sales data is the primary evidence.
- Unequal appraisal (“equal and uniform”). A Texas-specific argument: even if your appraised value matches market value, you can win a reduction if comparable properties are appraised at lower per-square-foot rates than yours. Texas Property Tax Code §41.43(b)(3) is unique to Texas and is often the easier path to a win because it doesn’t require proving market value is wrong — just that you’re being treated unequally.
The Texas Protest Process
- File Notice of Protest (Form 50-132) with your CAD by May 15 or within 30 days of your notice. Most CADs accept online filing.
- Informal review with a CAD appraiser. Many protests settle here. Bring your evidence and a specific requested value.
- Formal Appraisal Review Board (ARB) hearing if the informal didn’t resolve it. ARB members are local citizens, not CAD employees. You have ~15 minutes to present.
- Post-ARB options: binding arbitration (for residential homestead under $5M) capped at filing fees of ~$450, OR district court appeal, OR State Office of Administrative Hearings (SOAH) for non-homestead.

Building a Winning Texas Comp Set
Texas ARBs respond best to four to six recent sales within a half-mile of the subject, sold within the last 12 months, and within 20% of the subject’s square footage. Adjust for differences in lot size, age, and condition. Photos of deferred maintenance — foundation cracks, dated kitchens, roof age — support downward adjustments compared to renovated comps.
For an unequal-appraisal argument, pull the appraised values (not sale prices) of 5-10 similar nearby properties from the CAD’s public website and compute their median appraised value per square foot. If your appraised $/sqft is materially above that median, you have a strong §41.43(b)(3) case — even with no recent sales.
Homestead Cap & Why Protests Still Matter
Texas caps annual appraised-value increases on a homestead at 10% per year (Texas Tax Code §23.23). However, the market value can still rise above your capped appraised value — and that uncapped market value is what your protest targets. Reducing the market value also reduces the headroom under the cap, which compounds savings over multiple years.
Common Texas Protest Mistakes
- Arguing taxes are too high. The ARB has no power over tax rates — only the appraised value.
- Using stale comps. Anything older than 12 months gets discounted heavily.
- Ignoring the equal-and-uniform path. If your home is correctly priced but your neighbors are underpriced, file under §41.43(b)(3).
- Skipping the informal. Many homeowners go straight to the ARB and miss an easier settlement.
