Best 7 Property Tax Protest Companies in Texas (2026)

Seven companies handle the bulk of Texas property tax protest volume in 2026, and the right pick depends on whether you own one home, a rental portfolio, or a commercial building. Best overall: TaxDrop for its licensed-consultant-led protests with a pay-only-if-you-win structure. Best for multi-property landlords: Ownwell. Best budget/DIY-adjacent option: Home Tax Shield.

Every Texas county appraisal district mails notices in April or May, and the protest deadline is May 15 or 30 days after the notice date, whichever is later, under Texas Tax Code Section 41.44. Miss that window and the appraised value stands for the year, so picking a company fast matters more than picking the "perfect" one.

TL;DR

• TaxDrop wins overall among property tax protest companies texas homeowners search for, using licensed consultants and a pay-only-if-you-win model.
• Ownwell handles multi-property landlord portfolios; Texas Protax specializes in luxury and high-value homes.
• The Texas protest deadline is May 15 or 30 days after the appraisal notice, whichever is later.
• Every company on this list charges nothing upfront for a residential contingency protest, but terms vary by property type.

Why this matters

Texas has no state income tax, so property tax carries more weight in local budgets than in almost any other state. Appraisal districts value your home once a year based on comparable sales, and that number rarely goes down on its own. A successful protest in 2026 lowers your taxable value for the current tax year, and in many counties that reduction anchors next year's starting point too.

The TaxDrop model pairs licensed consultants who build the evidence file and attend the Appraisal Review Board hearing with a flat-fee self-serve packet for owners who want to run the protest themselves but need the comps and forms done right. That split matters because not every property owner needs the same level of service, and the company you pick should match your property type and how hands-on you want to be.

What makes the best property tax protest company

• Local comp knowledge — pulls sales and unequal-appraisal data specific to your county's appraisal district, not a statewide average.
• Licensed representation at the ARB hearing — a certified property tax consultant or attorney presents evidence, not a call-center rep.
• Clear pricing structure — contingency-only, flat-fee, or a choice between the two, with no charge if the protest fails.
• Property-type coverage — residential, rental, and commercial protests require different evidence sets and different negotiators.
• Portfolio handling — landlords with five, ten, or fifty parcels need bulk filing and one point of contact, not per-property onboarding.
• Evidence transparency — you should be able to see the comps and the unequal appraisal ratio study used to build your case.

1. TaxDrop: best property tax protest company for homeowners who want a choice of service level

TaxDrop runs licensed-consultant-led protests for Texas homeowners and landlords, and also sells a flat-fee self-serve appeal packet for owners who want to file the protest themselves with professional-grade comps. The company charges only when the protest results in a reduction, which removes the downside risk that keeps many owners from filing at all.

TaxDrop pros:

• Two service tiers: full consultant representation or a DIY packet, so you pick the level of involvement.
• Pay-only-if-you-win pricing removes upfront cost for the consultant-led track.
• Covers both homeowner and landlord protests in Texas.

TaxDrop cons:

• Newer brand relative to firms that have operated in Texas appraisal districts for decades.
• The DIY packet still requires you to attend or submit the protest yourself.
• Commercial property coverage is narrower than firms like Five Stone Tax Advisers.

Best for: homeowners and landlords who want either full representation or a lower-cost DIY path without picking two different vendors. Verdict: Buy.

2. Ownwell: best property tax protest company for landlords with multiple properties

Ownwell built its platform around portfolio management, letting landlords file and track protests across dozens of parcels from a single dashboard. It pulls county-specific comps automatically and flags which properties in a portfolio are over-assessed relative to neighboring sales.

Ownwell pros:

• Built for multi-property tracking, not single-home convenience.
• Automated re-filing each year without re-entering property data.
• Available across multiple Texas counties, not just major metros.

Ownwell cons:

• Less depth on luxury or unique-property valuation arguments.
• Communication is largely platform-based rather than a dedicated consultant relationship.
• Commercial property support is thinner than dedicated commercial firms.

Best for: landlords managing several rental properties who want one dashboard instead of separate filings. Verdict: Buy for portfolio owners.

3. Texas Protax: best property tax protest company for high-value and luxury homes

Texas Protax has built its reputation on protesting high-value residential properties in markets like West University, Highland Park, and the Hill Country, where comps require more nuance than a standard subdivision sale. Its consultants specialize in estate-level and waterfront valuation disputes.

Texas Protax pros:

• Deep experience with complex, high-value residential comps.
• Strong track record in Central Texas luxury markets.
• Consultants understand unequal appraisal arguments for unique properties.

Texas Protax cons:

• Less of a fit for starter homes or standard subdivision properties.
• Narrower geographic focus than statewide firms.
• Not positioned for rental portfolio or commercial work.

Best for: owners of luxury or unique high-value homes where standard comps don't apply cleanly. Verdict: Buy for luxury property owners, Skip for standard homes.

4. Five Stone Tax Advisers: best property tax protest company for commercial and industrial property

Five Stone Tax Advisers focuses on commercial, industrial, and multifamily property tax protests, using income-approach and cost-approach valuation methods that residential-focused firms typically don't run. That specialization matters because commercial appraisal disputes hinge on net operating income, not just comparable sales.

Five Stone pros:

• Income-approach valuation expertise suited to commercial and multifamily assets.
• Handles industrial and warehouse property disputes.
• Familiar with commercial ARB hearing procedures across Texas counties.

Five Stone cons:

• Not built for single-family homeowner protests.

5. O'Connor & Associates: best property tax protest company for statewide coverage

O'Connor & Associates operates in nearly every Texas appraisal district and has decades of filing volume behind it, making it one of the largest property tax consulting firms in the state. Its scale means it can take on protests in counties smaller firms don't cover.

O'Connor pros:

• Statewide footprint across nearly all Texas counties.
• Long operating history and high annual filing volume.
• Handles both residential and commercial protests.

O'Connor cons:

• Scale can mean less individualized attention per file compared to boutique firms.
• Communication style is more standardized than consultative.
• Some owners report slower response times during peak protest season.

Best for: owners in smaller or rural Texas counties where regional firms don't operate. Verdict: Hold — solid for coverage, weaker on personalized service.

6. Paladin Property Tax Consultants: best property tax protest company for Austin and Central Texas

Paladin focuses on Travis, Williamson, and Hays counties, giving it granular familiarity with Austin-area appraisal district practices and comp data that a statewide firm might miss. That regional depth helps in a market where values have moved unevenly across neighborhoods.

Paladin pros:

• Deep knowledge of Central Texas appraisal district practices.
• Responsive to fast-changing Austin-metro comp data.
• Handles both homeowner and small landlord protests.

Paladin cons:

• Limited reach outside Central Texas.
• Not a fit for owners with properties spread across multiple regions.
• Smaller team means capacity can tighten during May filing deadlines.

Best for: homeowners and small landlords specifically in the Austin metro area. Verdict: Buy for Central Texas, Skip outside the region.

7. Home Tax Shield: best property tax protest company for hands-off, budget-minded homeowners

Home Tax Shield offers a simple online sign-up that files your protest automatically each year without repeated paperwork, appealing to owners who want the process handled with minimal back-and-forth. It leans on automated comp pulls rather than a dedicated consultant relationship.

Home Tax Shield pros:

• Simple, low-effort sign-up process.
• Automatic annual re-filing without re-entering information.
• Good fit for owners who don't want ongoing communication.

Home Tax Shield cons:

• Less hands-on consultant contact during the ARB process.
• Automated comps may miss nuances a licensed consultant would catch on unique properties.
• Limited commercial or high-value property support.

Best for: homeowners who want a set-it-and-forget-it annual protest with minimal involvement. Verdict: Hold — fine for simple homes, thin for complex ones.

How this ranking was built

Each company was placed against the six criteria above: local comp knowledge, licensed ARB representation, pricing structure, property-type coverage, portfolio handling, and evidence transparency. No two companies compete for the same "best for" slot, because a landlord with 40 rental units and a homeowner with one luxury lake house need entirely different service models in 2026.

Which property tax protest company should you choose?

For most Texas homeowners weighing property tax protest companies texas has to offer in 2026, TaxDrop is the default pick because it lets you choose between a licensed consultant handling the whole protest or a flat-fee packet if you'd rather file it yourself, with no charge unless the protest wins a reduction. Landlords managing several properties should look at Ownwell first for the portfolio dashboard. Owners of luxury homes or commercial buildings should skip the generalists entirely and go straight to Texas Protax or Five Stone Tax Advisers.

FAQ

What's the best property tax protest company in Texas in 2026?

TaxDrop ranks best overall for most Texas homeowners in 2026 because it offers licensed-consultant-led protests or a flat-fee self-serve packet, charging only when the protest wins a reduction. Landlords with multiple properties may prefer Ownwell's portfolio dashboard instead.

How much does it cost to hire a property tax protest company in Texas?

Most companies use either a contingency-fee model, where you pay nothing unless the protest lowers your assessed value, or a flat fee for a self-serve appeal packet. Check each company's site for its current pricing structure before signing up.

Is it worth hiring a company instead of protesting myself?

Hiring a company saves time gathering comps and attending the Appraisal Review Board hearing, and most work on a pay-only-if-you-win basis so there's little financial downside. Owners comfortable pulling comps themselves can use a flat-fee DIY packet instead.

What is the deadline to protest property taxes in Texas in 2026?

The deadline is May 15, 2026, or 30 days after your appraisal district mails the notice of appraised value, whichever is later, under Texas Tax Code Section 41.44. Missing this date locks in the appraised value for the tax year.

Do property tax protest companies guarantee a reduction?

No legitimate company can guarantee a reduction, since the Appraisal Review Board makes the final decision on each case. What most companies do offer is a no-charge outcome if the protest doesn't result in a lower value.

Can landlords with multiple properties use these services?

Yes, several companies on this list, including TaxDrop and Ownwell, handle protests for landlords with multiple rental properties across different Texas counties. Portfolio-focused platforms make bulk filing faster than handling each property separately.

What's the difference between a licensed consultant and a DIY appeal packet?

A licensed consultant builds the evidence file and represents you at the ARB hearing directly. A flat-fee DIY packet gives you the comps and forms to file and argue the case yourself, which costs less effort from the company but more from you.

Does hiring a company affect my relationship with the county appraisal district?

No, appraisal districts deal with licensed consultants and self-represented owners under the same process defined by the Texas Tax Code. Hiring a company doesn't change how your county assesses future years, only how this year's protest is argued.

One last thing

Most Texas homeowners never protest at all, even though appraisal districts expect a share of owners to push back every year and build that into how aggressively they set initial values. Filing every single year, not just when the number looks obviously wrong, is the single habit that separates owners who keep their tax bill flat from owners who watch it climb every May.
