How to Protest Your Property Tax Appraisal in Travis, Williamson & Hays County

You have the right to protest your property tax appraisal every single year, it costs nothing to file, and in a market like Austin's, where values move fast, a meaningful share of protests end with a lower assessed value. In short: if the notice of appraised value from your county looks too high, you can file a protest with your county appraisal district before the deadline, present a little evidence, and often lower the number your taxes are based on. Here is exactly how to do it in Travis, Williamson, and Hays counties.

This guide walks through the deadline, how and where to file, the evidence that actually moves the needle, what to expect at your hearing, and whether it is worth hiring a protest company.

Why Protesting Is Worth Your Time

County appraisal districts value hundreds of thousands of homes using mass-appraisal models, not individual walk-throughs. That means the value on your notice is an estimate, and estimates can be too high, especially if your home has condition issues or the district has the wrong details on file. Lowering your assessed value lowers your tax bill for the year, and because Texas caps how much a homestead's assessed value can rise annually, keeping your number in check has a compounding effect over time. Pair a successful protest with your Texas homestead exemption, which limits annual increases in your assessed value, and you have two of the most effective tools for controlling what you pay.

Know Your Deadline

The deadline to protest is typically May 15, or 30 days after the appraisal district mails your notice of appraised value, whichever is later. Put the date on your calendar the moment your notice arrives. If you are on the fence, file anyway. Filing preserves your right to a hearing, and you can always withdraw or settle informally if you change your mind.

How to File in Travis, Williamson, and Hays County

You file with the appraisal district for the county your home sits in, not the tax office. Each district runs its own process, and most now offer an online protest portal that lets you submit your protest and evidence without ever going in person. Homes in West Lake Hills and Lakeway file with the Travis Central Appraisal District; homes in Georgetown and Round Rock file with the Williamson Central Appraisal District; and homes in Kyle and Buda file with the Hays Central Appraisal District. Check your notice, it names your district and gives you the account number you will need.

Build Your Evidence

A protest is only as strong as the evidence behind it. The most persuasive arguments usually fall into a few buckets:

• Comparable sales: recent sales of similar nearby homes that sold for less than your assessed value.
• Condition issues: photos and estimates for needed repairs, foundation or roof problems, or dated systems that lower your home's real market value.
• Unequal appraisal: evidence that comparable homes in your neighborhood are assessed for less than yours.
• Data errors: mistakes in the district's records, such as wrong square footage or the wrong number of bedrooms or bathrooms.

Informal vs. Formal Hearing

Most protests are resolved at the informal stage, where you meet or exchange evidence with a district appraiser and try to agree on a value. If you cannot reach agreement, your protest goes to a formal hearing before the Appraisal Review Board, an independent panel that hears both sides. Either way, the winning approach is the same: be organized, stick to the facts, present your comps and photos clearly, and keep it professional rather than emotional.

Should You Hire a Protest Company?

You can absolutely protest yourself. It is free, and you keep 100 percent of the savings. Protest firms handle the paperwork and hearing for you and typically charge a contingency fee, often a share of your first-year tax savings. For a straightforward homestead, doing it yourself is very manageable. For a higher-value or more complex property, a firm's time savings and experience can be worth the fee. Either way, the key is to actually file.

Frequently Asked Questions About Property Tax Protests

When is the property tax protest deadline in Central Texas? It is generally May 15, or 30 days after your appraisal district mails your notice of appraised value, whichever is later. Always confirm the exact date on your notice.

Does protesting actually lower my taxes? It can. A protest challenges your assessed value, and if you succeed in lowering that value, your tax bill for the year drops with it.

Can protesting raise my taxes? In practice, no. The review focuses on the value the district already proposed, so filing a protest is a low-risk step for most homeowners.

What evidence do I need to protest? Comparable sales below your value, photos and estimates of needed repairs, evidence that similar homes are assessed lower, and any corrections to the district's data on your home all help.

Should I protest every year? Many homeowners do, because appraisal districts reset values annually. It is worth reviewing your notice each year and filing whenever the value looks high.

How does the homestead exemption fit in? Your homestead exemption caps how much your assessed value can increase each year and lowers your taxable value, so it works hand in hand with protesting. Learn more in our guide to the Texas homestead exemption.

Do I need to hire a company to protest? No. You can file and present your own protest for free, though some owners of higher-value or complex properties choose to hire a firm that works on contingency.
