How to Protest Property Taxes in Texas: A Step-by-Step Guide for Investors

Every May in Texas, county appraisal districts mail out Notice of Appraised Value letters to property owners. Most landlords glance at the number, compare it vaguely to what they paid, and toss the letter. That's expensive. Successful protests regularly cut assessed values by 10–30%, and every dollar of reduced assessed value translates directly into reduced property tax liability for years.

For investment properties specifically, protesting is more consequential than for homesteads. Owner-occupants have the 10% annual appraisal cap as a buffer. Investment properties have no such cap — the county can raise your assessed value 30–50% in a single year to reflect market conditions. The protest process is your primary check against this.

Understanding Who Sets Your Tax Bill

Texas property taxes are administered at the county level by Central Appraisal Districts (CADs). The appraisal district determines the assessed value. Separate local taxing entities — county government, school district, municipal utility district — set tax rates. Your tax bill is assessed value × aggregate tax rate.

Protesting works on the assessed value side. You cannot protest the tax rate directly; that requires engaging your taxing entities through the budget process.

Step 1: Check Your Protest Deadline

The standard protest deadline in Texas is May 15 or 30 days after the date your Notice of Appraised Value was mailed, whichever is later. Check the notice for the exact mailing date. Missing this deadline eliminates your protest right for the current tax year.

If you acquired a new property and did not receive a notice, you have until the date the taxes become delinquent (typically February 1 of the following year) to file a late correction protest — but this is narrower in scope.

Step 2: File Your Protest

File with the Appraisal Review Board (ARB) for your county. Every major Texas county offers online filing through its CAD portal:

• Harris County: hcad.org
• Dallas County: dallascad.org
• Bexar County (San Antonio): bcad.org
• Travis County (Austin): traviscad.org
• Tarrant County (Fort Worth): tad.org

Submit your protest before the deadline, even if you don't have all your evidence assembled yet. You can gather documentation before the hearing. The protest itself simply preserves your right to be heard.

When filing, you have two grounds:

Unequal appraisal: Your property was assessed at a value that is unequal compared to similar properties in the same CAD. This is often the stronger argument for investment properties.

Value exceeds market value: The assessed value exceeds what your property would sell for in an arm's-length transaction.

File both grounds. You don't need to choose.

Step 3: Build Your Evidence Package

This is where the outcome is decided before you walk in the room.

Comparable sales analysis (comps). Pull closed sales of similar properties in your immediate neighborhood — same size, age, condition — from the past 12 months. Use the CAD's own website, the MLS if you have access, or free sources like Zillow, Redfin, or Realtor.com (filter to "sold"). If 3 comparable sales average out to $280,000 and your assessed value is $340,000, that's your core argument.

Comparable assessed values (equity comps). This is the unequal appraisal argument. Search the CAD's public database for similar properties nearby. If your property is assessed at $340,000 and five comparable properties are assessed at $280,000–$300,000, the district is applying unequal standards. Texas Tax Code Section 41.43 requires appraisal districts to use the median appraisal ratio of comparable properties — this argument frequently wins.

Property condition evidence. If your property has foundation issues (common in DFW, Austin, and San Antonio Blackland Prairie zones), deferred maintenance, major system replacements needed, or flood history, document it. Photos, contractor quotes, and inspection reports all support a reduced value.

Recent purchase price. If you bought the property within the past year, the purchase price is highly persuasive evidence of market value — especially if it was an arm's-length transaction at market rate.

Rental income approach. For income-producing properties, you can argue value based on income capitalization. If your property generates $18,000 in annual net operating income (NOI) and the prevailing cap rate in your submarket is 6%, the income approach suggests a market value of $300,000. This is the argument to lead with when comparable sales data is thin.

Step 4: Request an Informal Review

Most Texas CADs offer an informal review with an appraiser before the formal ARB hearing. Take it. Appraisers at the informal stage have more flexibility to settle — they're not constrained by the formal proceeding rules. The majority of protests are resolved at this stage.

Come to the informal review with your comps organized and a specific target value. Not "I think it's too high" — "Based on these three closed sales and four equity comps, market value is $285,000." Be specific and document-heavy, not emotional.

If the informal review produces a settlement offer you're satisfied with, accept it and confirm it in writing. If not, proceed to the ARB hearing.

Step 5: The ARB Hearing

The Appraisal Review Board is a panel (typically 3 members) appointed by the county administrative judge. They're not CAD employees. The appraiser presents the district's evidence; you present yours. The burden of proof matters:

• If the district's assessed value exceeds $1 million, the burden of proof shifts to the district to prove market value by clear and convincing evidence.
• Below $1 million, you bear the burden of establishing that the assessed value is incorrect.

Keep your presentation factual and brief. Show your comps. Show the equity comps. State your requested value clearly. ARB panels hear hundreds of cases; they respond to organized, document-backed arguments.

You'll receive the ARB's decision by mail within a few days. You have 45 days to appeal an unfavorable ARB decision to district court, or alternatively to binding arbitration (for properties valued under $5 million) or the State Office of Administrative Hearings (SOAH).

Protest Every Year Without Exception

First-year results are often modest because appraisers know they'll need to defend the value. Successive protests get easier as your documented position builds. In rapidly appreciating markets like DFW or Austin, annual protests have saved investors $2,000–$6,000 per property per year. Over a 5-year hold, that's material.

Texas law also allows multi-year agreements with the CAD (through a Section 1.111 agent agreement) if you hire a property tax agent. Agents work on contingency — typically 30–50% of first-year savings — with no fee if they don't reduce your value.

What Investment Properties Face That Homesteads Don't

Owner-occupants have the homestead cap: the taxable value of a primary residence cannot increase more than 10% per year regardless of what the market does. Investment properties get a partial version of this through the 20% circuit breaker cap (for non-homestead properties valued under $5 million), introduced in 2024 — but a 20% cap still means your effective tax bill can jump substantially in a single reassessment.

This asymmetry means investment property owners have a stronger incentive to protest annually than homestead owners. Every point you can hold the assessed value below market also compounds as a tax base for future years.
