How Property Tax Protests Work in Texas (And When to File)

In Texas, property taxes are one of the biggest ongoing costs of owning a home, and your annual appraisal directly affects your monthly mortgage payment through escrow. The good news: you have the right to protest your appraised value every year. This guide explains how the protest process works, the key deadlines (typically by May 15 or 30 days after your notice arrives), what evidence helps your case, and when it makes sense to file.

Why Protesting Matters

Each year, your county appraisal district estimates the market value of your home, and that value drives your property tax bill. Because most homeowners pay taxes through escrow, a higher appraisal can quietly raise your monthly mortgage payment. Protesting gives you a chance to challenge a value you believe is too high. Even a modest reduction can save you money every year you own the home, which is why many Texas homeowners make protesting a routine part of their spring.

Know the Deadlines

Timing is everything with a protest. Appraisal districts mail value notices in the spring, and you generally must file your protest by May 15 or within thirty days of the date your notice was sent, whichever is later. Missing the deadline usually means waiting until the following year, so mark your calendar when your notice arrives. Filing is straightforward and can often be done online, by mail, or in person with your county appraisal district.

Gather Strong Evidence

A successful protest rests on evidence. The most persuasive support is recent sales of comparable homes in your area that sold for less than your appraised value. Photos and repair estimates documenting problems such as foundation issues, roof damage, or needed updates can also lower your value. You can request the appraisal district’s own evidence packet to see how they arrived at their number, which often reveals errors in square footage, lot size, or condition that you can point out.

What to Expect From the Process

After you file, many districts offer an informal meeting with an appraiser where a large share of protests are resolved. If you cannot reach agreement, your case goes to a formal hearing before the appraisal review board, an independent panel that hears your evidence and the district’s, then sets a value. Most homeowners never need to go beyond the informal stage. Be organized, stick to the facts, and present your comparable sales clearly.

When It Makes Sense to File

It is usually worth protesting any year your appraised value rises sharply or appears higher than what similar homes are selling for. The process is free to file, the potential savings recur year after year, and the district cannot raise your value simply because you protested. If you would rather not handle it yourself, you can hire a protest service that works on a contingency fee. Either way, reviewing your notice each spring and protesting when the numbers warrant it is one of the simplest ways to keep your housing costs in check.
