How to Protest Your Texas Property Tax in 2026: The Complete Guide

Why You Should Protest Your Texas Property Tax

Every year, Texas county appraisal districts estimate the market value of your home. That estimated value directly determines how much property tax you owe. The problem? These assessments are often too high.

When your home is over-assessed, you overpay property tax — not just once, but every year until the value is corrected. The good news is that Texas law gives every homeowner the right to protest their property tax assessment, and it works more often than you might think.

In Harris County alone, more than 300,000 property owners file protests every year. Those who succeed save an average of $500 to $1,500 annually. Yet the majority of Texas homeowners never protest at all, simply because they don't know how — or assume it's too complicated.

It's not. This guide walks you through everything you need to know.

The 2026 Property Tax Protest Deadline

The most important date to remember: May 15, 2026.

This is the deadline to file a property tax protest for most Texas counties. After this date, there are no extensions and no exceptions. If you miss it, you'll pay your current assessed amount for the full year.

A few counties have slightly different deadlines — Dallas County's deadline is May 17, 2026 — but May 15 is the safe date to work with.

You can file your protest as early as January 1, so there's no reason to wait until the last minute. In fact, filing earlier gives you more time to prepare evidence and increases your chances of a favorable outcome.

How Texas Property Tax Assessment Works

Understanding how your property tax is calculated helps you know when to protest and how to build your case.

Step 1: Your County Appraises Your Home

Each January, your county appraisal district (like HCAD for Harris County, DCAD for Dallas, or TCAD for Travis County) determines the market value of your property. They use a combination of recent sales data, property characteristics, and mass appraisal techniques.

Step 2: You Receive an Appraisal Notice

In April, you'll receive a Notice of Appraised Value in the mail. This tells you what the county thinks your home is worth for the 2026 tax year. Compare this number to what your home would actually sell for — if the county's number is higher, you have grounds to protest.

Step 3: Your Tax Bill Is Calculated

Your property tax bill is calculated by multiplying the assessed value by your local tax rate (which includes school district, city, county, and other taxing entities). In most Texas metros, the combined tax rate is between 2% and 3% of your assessed value.

This means that even a modest $30,000 reduction in your assessed value can save you $600 to $900 per year.

How to File a Property Tax Protest

You have three main options for filing your protest.

Option 1: File It Yourself (Free)

You can file a protest directly with your county appraisal district. Most counties accept online filings through their website. You'll need to fill out a Notice of Protest form and specify the reason for your protest — typically "Value is over market value" or "Value is unequal compared with other properties."

After filing, the county will schedule an informal hearing where you can present evidence. If the informal hearing doesn't resolve it, you can escalate to a formal hearing before the Appraisal Review Board (ARB).

Pros: Free. You learn the process.

Cons: Time-consuming. You need to gather your own evidence and attend hearings during business hours. Most homeowners don't know what evidence is most effective.

Option 2: Hire a Property Tax Consultant

Professional property tax consultants file protests and attend hearings on your behalf. Most charge 25% to 40% of whatever they save you, with no upfront cost.

Pros: Professional expertise. Higher success rates.

Cons: Higher fees eat into your savings.

Option 3: Use Grounda (Recommended)

Grounda is a full-service property tax protest platform built specifically for Texas homeowners. You enter your address, review your tax data and insights, and authorize Grounda to handle the rest — filing, evidence preparation, and hearings.

What makes Grounda different:

• See your data first. Before you sign anything, you can look up your property, view your tax bill history, compare with similar homes, and understand whether a protest makes sense. No other service gives you this level of transparency before asking for your authorization.

• Lower fee. Grounda charges 20% of your savings — compared to the industry standard of 25% to 35%. You keep more of what you save.

• No upfront cost. You only pay if Grounda successfully reduces your assessed value. If there's no savings, you pay nothing.

• Full service. Filing, evidence gathering, informal hearing, and ARB hearing — all handled for you.

To get started, visit grounda.ai, enter your address, and review your property data. You can decide whether to authorize a protest after seeing the numbers.

What Evidence Works Best

Whether you file yourself or use a service, the strength of your protest depends on your evidence. Here are the most effective types:

Comparable Sales (Most Important)

Find 3 to 5 recent sales of similar homes near yours that sold for less than your county's assessed value. "Similar" means comparable in size, age, condition, and location. Recent means within the last 6 to 12 months.

If your neighbor's similar home sold for $370,000 but the county says yours is worth $425,000, that's strong evidence of over-assessment.

Unequal Appraisal

Even if the county's value is close to market value, you can argue that your home is appraised higher than comparable properties in your area. If similar homes on your street are assessed at $380,000 but yours is assessed at $425,000, that's unequal appraisal — and Texas law says it shouldn't happen.

Property Condition Issues

If your home has problems that reduce its value — foundation issues, roof damage, outdated systems, flood zone location — document them with photos and repair estimates. The county's mass appraisal often doesn't account for individual property conditions.

Photos and Documentation

Bring photos of any condition issues, printouts of comparable sales, and a clear summary of your argument. Organized evidence makes a better impression at hearings.

The Protest Timeline

Here's what to expect after you file:

Filing (Now through May 15): Submit your protest online or through a service like Grounda.

Informal Hearing (May through July): You or your representative meets with an appraiser from the county to discuss the evidence. Many protests are resolved at this stage with a negotiated reduction.

Formal ARB Hearing (if needed): If the informal hearing doesn't produce a satisfactory result, you can present your case to the Appraisal Review Board — a panel of citizens who make a binding decision.

Result: If your protest is successful, your assessed value is reduced, and your tax bill decreases accordingly. The savings apply to the current tax year and often carry forward.

County-Specific Tips

Harris County (Houston)

Harris County is the largest county in Texas with over 1.8 million parcels. HCAD (Harris County Appraisal District) processes hundreds of thousands of protests every year. The sheer volume means many cases are settled quickly at the informal stage. Filing early gives you better hearing times.

Dallas County

Dallas County uses DCAD for appraisals. The protest deadline is May 17, 2026 — two days later than most counties. Dallas has seen rapid appreciation in recent years, making protests especially valuable for homeowners whose values have been pushed up aggressively.

Travis County (Austin)

Travis County (TCAD) has experienced some of the highest appreciation rates in the state. If you bought your home before 2022, your assessed value may have increased dramatically. Austin homeowners often see the largest dollar savings from successful protests.

Tarrant County (Fort Worth) and Bexar County (San Antonio)

Both counties follow the standard May 15 deadline and have active protest programs. Similar strategies apply — focus on comparable sales and unequal appraisal evidence.

Frequently Asked Questions

Does it cost anything to protest?

Filing a protest yourself is free. If you use a service like Grounda, you only pay if they successfully reduce your assessed value (20% of savings for Grounda, 25-35% for most competitors).

What if my protest fails?

Your assessed value stays the same — it cannot increase as a result of your protest. There's no risk in filing.

Can I protest every year?

Yes. Many homeowners protest every year, especially in areas with rising property values. Each year's assessment is independent.

How much can I save?

It depends on how much your home is over-assessed. The average successful protest in Texas saves $500 to $1,500 per year. Homes with larger over-assessments can save significantly more.

Do I need to attend a hearing?

If you file yourself, yes — either in person or virtually. If you use Grounda or another service, they attend hearings on your behalf using a signed Power of Attorney.

What's the difference between market value and assessed value?

Market value is what your home would sell for on the open market. Assessed value is what the county appraisal district says it's worth for tax purposes. Your goal in a protest is to show that the assessed value is higher than the actual market value.
