Home / Resources / Texas Property Tax Protest Guide

If you're a Texas homeowner, there's a good chance you're paying more in property taxes than you should. Texas has no state income tax, which means local governments rely heavily on property taxes — and that means appraisal districts have an incentive to value your property as high as possible.

The good news? Texas law gives you the right to protest your property tax appraisal every year, and the process is more straightforward than most homeowners realize. Over half of all property tax protests in Texas result in some reduction.

Understanding Texas Property Taxes

In Texas, your county's Central Appraisal District (CAD) determines the appraised value of your property each year. Your property tax bill is calculated by multiplying this appraised value by the combined tax rates of all the jurisdictions you're in (city, county, school district, special districts).

The average effective property tax rate in Texas is approximately 1.60% to 2.50%, depending on the county. That means on a $400,000 home, you could be paying $6,400 to $10,000 per year in property taxes. Even a 5-10% reduction in your appraised value can save you hundreds of dollars annually.

Key Deadlines for 2025

• January 1 — Appraisal date. Your property is valued as of this date.
• April 1 - May 1 — Most counties mail Notices of Appraised Value.
• May 15 — Standard protest filing deadline.
• May - September — Appraisal Review Board (ARB) hearings are scheduled.

Grounds for Protest

Texas law (Section 41.41 of the Texas Property Tax Code) allows you to protest on several grounds:

1. Market value is too high — The most common basis. Your appraised value exceeds fair market value.
2. Unequal appraisal — Your property is valued higher than comparable properties in your area. This is often the strongest argument.
3. Incorrect property data — Wrong square footage, lot size, year built, or other factual errors in the appraisal record.
4. Failure to send notice — You didn't receive your Notice of Appraised Value.
5. Exemption denied — You were denied a homestead or other exemption you're entitled to.

What Evidence Do You Need?

For a Market Value Protest

• Recent comparable sales (within the last 6-12 months) of similar properties in your area
• Photos showing property condition issues (deferred maintenance, foundation cracks, dated interiors)
• Professional appraisal if available
• Repair estimates for any needed work

For an Unequal Appraisal Protest

• Comparable properties with lower appraised values per square foot
• Statistical analysis showing your property is valued above the neighborhood median
• Properties with similar characteristics (size, age, lot, features) that are assessed lower
• Percentile ranking showing your property is in the upper range of neighborhood values

This is exactly what Home-Sage automates — our AI pulls comparable properties directly from your county's CAD data, calculates price-per-square-foot rankings, and generates charts and evidence tables ready for your protest filing.

The Protest Process: Step by Step

1. File Your Protest

You can file online through your county's CAD website, by mail, or in person. You'll need your property ID (found on your Notice of Appraised Value) and you'll select your grounds for protest.

2. Informal Hearing

Most counties offer an informal hearing first, where you meet with an appraiser to discuss your case. Many protests are resolved at this stage. Bring your evidence — comparable properties, photos, and data supporting your case.

3. Appraisal Review Board (ARB) Hearing

If the informal hearing doesn't resolve your protest, you'll attend a formal ARB hearing. This is a panel of citizens who will review your evidence and the appraisal district's position, then make a binding determination.

4. Further Appeals

If you disagree with the ARB's decision, you can file binding arbitration (for properties under $5 million) or appeal to district court.

Tips for a Successful Protest

• File early — don't wait until the deadline. Early filers often get better informal hearing slots.
• Focus on unequal appraisal — this is typically the strongest argument because it's based on how your property compares to your neighbors, not market conditions.
• Use data, not emotion — ARB panels respond to comparable property data, price-per-square-foot analysis, and objective evidence.
• Check your property details — verify your square footage, lot size, year built, and number of rooms are correct in the CAD records. Errors are more common than you'd think.
• Protest every year — even if you were denied last year, property values and comparables change annually.
