Williamson County

We protest in all of Williamson County.

Texas Tax Lock handles property tax protests for homeowners throughout Williamson County, including Round Rock, Georgetown, Cedar Park, Leander, Hutto, Taylor, Liberty Hill, Jarrell, Florence, Weir, Granger, Thrall, and Walburg.

The Williamson Central Appraisal District (WCAD) appraises all property in the county. Williamson County was ground zero for Austin's expansion boom, with tech company relocations and remote work migration driving enormous demand in cities like Cedar Park, Leander, and Georgetown. WCAD's appraisals surged accordingly — and for many homeowners, assessed values remain elevated even as the market has partially softened.

The deadline to file a protest with WCAD is May 15, 2026. We handle the filing, comparable sales analysis, unequal appraisal research, and all informal and ARB hearing representation. You sign up — we take care of the rest.

How It Works

Three steps. You do almost nothing.

STEP 01
Sign Up in 2 Minutes

Enter your property address and 2026 notice value. We immediately register as your authorized agent with WCAD and file your protest before the May 15 deadline. No paperwork on your end.

STEP 02
We Build Your Case

Our team pulls comparable sales from WCAD's records and MLS data, runs unequal appraisal analysis, and prepares a complete evidence package. We identify the strongest argument for your specific property — not a one-size-fits-all submission.

STEP 03
We Negotiate and Represent

We attend your informal hearing with WCAD and present the evidence. If informal doesn't resolve, we proceed to a formal ARB hearing. You don't appear. We notify you when there's a final result.

Why Flat Fee

You keep your savings.
We keep our fee.

Contingency-fee firms charge a percentage of your first year's tax savings — which means they take a cut of every dollar you save, every time. Our flat fee means you pay once, up front, and everything you save beyond that is yours to keep.

On a $50,000 value reduction at a 2.3% tax rate, you save approximately $1,150 per year — and every year after. A 25% contingency firm would take $288+ from year one alone. Our fee: $199.

Common Questions

What Williamson County homeowners ask us.

What is WCAD and how does it affect my tax bill?
WCAD — the Williamson Central Appraisal District — appraises all real property in Williamson County for ad valorem tax purposes. The values WCAD sets are used by Round Rock ISD, Georgetown ISD, Leander ISD, Hutto ISD, and other taxing entities to calculate your property tax bill. Your Notice of Appraised Value comes from WCAD. If that value is higher than what comparable sales support, a formal protest is the mechanism to reduce it — and that's exactly what we file and argue on your behalf.
What's the deadline to file a protest?
The statutory protest deadline in Texas is May 15, 2026, or 30 days after your Notice of Appraised Value — whichever is later. Sign up before that date and we handle the filing. Earlier sign-ups give us more time to build the strongest case for your property.
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. On a typical $5,000 value reduction, a contingency firm at 25% would take $28.75 or more from your first-year savings. We take $199. On a $50,000 reduction at $1,150 in annual savings, a contingency firm takes $288+. We still take $199.
What evidence does Texas Tax Lock use to argue my value?
We use two primary approaches: comparable sales analysis — recent sales of similar properties in your area that support a lower value — and unequal appraisal, which shows that similar homes in your area are assessed lower than yours on a per-square-foot basis. Texas law requires the appraisal district to correct unequal appraisals. We pull data directly from the CAD's own records and market databases, so the evidence is grounded in the same sources the district uses.
Do I need to attend any hearings?
No. As your appointed agent, we handle all communications, negotiations, and appearances with the appraisal district and the Appraisal Review Board on your behalf. You don't appear, call in, or prepare anything. We notify you when the process is complete and tell you the final result.
How long does the protest process take?
Informal negotiations typically run from late spring through early summer, often resolving by June or July. If a case proceeds to a formal ARB hearing, the timeline can extend into late summer or early fall. The appraisal district controls the schedule; we move as fast as they allow. You'll hear from us when there's a result.
Can I protest multiple properties?
Yes — add as many properties as you own in the signup form. Two or more properties automatically qualify for a 15% discount on the total. We file and represent each property separately with the appropriate appraisal district.
Williamson County values rose sharply — has WCAD corrected them as the market softened?
Partially — but not uniformly. WCAD has made some reductions in areas where comparable sales clearly support lower values, but mass appraisal methodology means individual properties often remain over-assessed even when the broader market has softened. This is especially true in neighborhoods where new construction comps don't accurately represent resale values, or where WCAD's model has lagged in recognizing specific location or condition factors. A targeted comparable sales analysis for your specific property — not just the zip code — is the most effective way to identify and argue the gap.
