Texas reassesses every year — the fight is renewable
Texas has the most owner-friendly property tax protest system in the US — and also some of the highest property tax rates. No state income tax means the state relies heavily on property tax, and the effective rate on luxury homes in the Dallas, Houston, and Austin markets commonly runs 1.8–2.5%. On a $5M estate, that is $90,000–$125,000 per year. The good news: Texas law guarantees every owner the right to protest annually, 60–80% of protests result in reductions, and the informal review process at the appraisal district resolves the majority of luxury cases without a formal ARB hearing.

The Texas Protest Process for Luxury Owners
Step 1: File Before May 15
The protest deadline for most Texas owners is May 15 or 30 days after the Notice of Appraised Value is mailed, whichever is later. Filing the Form 50-132 Notice of Protest with your county appraisal district preserves your right to be heard. File immediately when you receive the notice — you can build the evidence case in the weeks before your informal review. Every major Texas county (Dallas, Tarrant, Harris, Travis, Collin, Denton) now offers online filing through the appraisal district portal.
Step 2: The Informal Review — Where Most Luxury Cases Resolve
After filing, the appraisal district schedules an informal review: a one-on-one meeting (in person, by phone, or video) with a district appraiser. This is where 80–90% of Dallas County protests resolve. Bring your evidence: comparable sales, a professional appraisal if you have one, photos of condition issues, and the property record card with any errors marked. The district appraiser has authority to reduce your value on the spot. The informal review is a negotiation, not a hearing. Be prepared, be specific, and be professional.
Step 3: The ARB Hearing (If Informal Fails)
If the informal review does not produce an acceptable reduction, you advance to the Appraisal Review Board (ARB): a panel of citizens (not appraisal district employees) who hear your evidence and the district’s evidence and make a determination. HB 1533 (effective 2025) requires appraisal districts to share their evidence with property owners at least 14 days before the ARB hearing — a significant change that levels the playing field. For a luxury property, a consultant or attorney at the ARB hearing is strongly recommended.
The Two Appeal Grounds That Win in Texas
Market Value Protest
Your property is appraised above what it would sell for in an arm’s-length transaction. Primary evidence: 3–5 comparable sales at prices below your assessed value. In a thin luxury market, add a professional appraisal.
Unequal Appraisal (Equity Appeal)
Your property is appraised at a higher ratio than comparable properties in the same appraisal district. Texas Tax Code §41.43(b) requires the ARB to rule in the owner’s favor if the appraised value exceeds the median appraised value of a reasonable number of comparable properties, properly adjusted. This is one of the strongest tools in Texas for luxury properties where the assessor’s mass-appraisal model applies a higher per-square-foot rate than neighboring comparable estates. A consultant with local data can build this case even when market-value comparables are thin.
Texas Effective Tax Rates for Luxury Markets
| Market | Typical Effective Rate | Annual Tax on $5M Property | Annual Tax on $10M Property |
|---|---|---|---|
| Dallas / Collin County | 1.8–2.2% | $90,000–$110,000 | $180,000–$220,000 |
| Harris County (Houston) | 1.9–2.3% | $95,000–$115,000 | $190,000–$230,000 |
| Travis County (Austin) | 1.7–2.1% | $85,000–$105,000 | $170,000–$210,000 |
| Tarrant County (Fort Worth) | 1.8–2.2% | $90,000–$110,000 | $180,000–$220,000 |
Rates vary by specific taxing entities (school district, city, county, MUD, PID). Verify with a local property tax consultant.
Texas Homestead Cap: What Luxury Owners Must Know
Texas’s homestead exemption limits annual appraisal increases to 10% for primary residences. Texas Proposition 13 (November 2025 ballot measure) increased the school district homestead exemption from $100,000 to $140,000. Critical detail: the 10% cap resets every time you buy a new home. A luxury buyer who purchases at market value in a rising market starts at full market value with no cap protection in year 1. Filing a protest in year 1 establishes the right baseline before the cap locks in. Note: the cap applies to appraisal value increases, not to tax rate increases. If local tax rates rise, your bill can increase by more than 10%.
Ryan Brown, Principal Broker & CEO — Own Luxury Homes®
“Texas is the best state in the country to fight your property taxes — and the one where most luxury owners leave the most money on the table. The informal review is a conversation. Show up with comparables, show up with a professional appraisal if you have it, and be specific about why the district’s number is wrong. The district appraiser has authority to reduce on the spot. Most of my clients’ Texas protests resolve at that stage, without a formal hearing, every single year.”
What is the Texas property tax protest deadline?
May 15 or 30 days after the Notice of Appraised Value is mailed, whichever is later. Confirm the exact date on your actual notice. Online filing is available for all major Texas counties.
What is an unequal appraisal protest in Texas?
A protest on the ground that your property is assessed at a higher ratio than comparable properties in the same district. Texas Tax Code §41.43(b) requires the ARB to rule in the owner’s favor if comparable properties (properly adjusted) have a lower median value. This is often the strongest argument for luxury properties where market comps are thin.
Should I hire a property tax consultant for my Texas luxury home?
Yes, strongly. The informal review resolves 80–90% of cases, but at $3M+ the comparables are more complex and the dollar amounts justify professional representation. Texas consultants typically charge 25–40% contingency of first-year savings, with nothing owed if they achieve no reduction.
