Serving All of Williamson County

Texas Tax Lock handles property tax protests for homeowners across Williamson County, including Round Rock, Georgetown, Cedar Park, Leander, and Taylor. With a population of approximately 800,000, Williamson County is served by the Williamson Central Appraisal District (WCAD).

Williamson County has been one of the fastest-growing counties in the entire country. WCAD values have surged alongside Austin metro growth — and a well-prepared protest can deliver real savings for homeowners in Round Rock, Georgetown, and Cedar Park.

The statutory deadline to file a protest is May 15, 2026 (or 30 days after your notice date, whichever is later). Don't wait — our process takes under 2 minutes online and we handle everything from filing through the final hearing.

— How It Works

Three steps. We do the work.

STEP 01
Sign Up Online

Enter your property address and notice value. Takes under 2 minutes. We file your protest with WCAD before the deadline.

STEP 02
We Build the Case

Our team pulls comps, reviews WCAD data, and prepares a full evidence package. You don't need to do a thing.

STEP 03
We Negotiate & Represent

We handle informal negotiations and formal ARB hearings with WCAD where it makes sense to pursue them.

— Pricing

Flat fee. No surprises.

One flat fee per property based on your 2026 Notice of Appraised Value from WCAD. No contingency fee on your savings.

— Common Questions

What Williamson County homeowners ask us

Do I need to do anything after I sign up?
No. Once you sign up we take it from there — filing, evidence gathering, and representation with WCAD. We'll contact you if we need anything additional.
What's the deadline to file a protest in Williamson County?
The statutory deadline is May 15, 2026 (or 30 days after your notice date, whichever is later). Sign up before that date and we'll handle the filing.
Is there a contingency fee if my value gets reduced?
No. Our fee is flat — based on your notice value, not your savings. You pay once and that's it, regardless of the outcome.
Can I protest multiple properties in Williamson County?
Yes. Add as many properties as you own in the signup form. Two or more properties automatically receive a 15% discount on the total.
Is this just for homestead properties?
We handle residential properties statewide. Reach out to us at support@texastaxlock.com if you have questions about a specific property type.
