Serving All of Collin County

Texas Tax Lock handles property tax protests for homeowners across Collin County, including Plano, McKinney, Allen, Frisco (part), Wylie, and Murphy. With a population of approximately 1.1 million, Collin County is served by the Collin Central Appraisal District (CCAD).

Collin County is one of the fastest-growing counties in the nation. CCAD values have climbed steadily — and many homeowners are overpaying without realizing a protest is available to them every single year.

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 CCAD before the deadline.

STEP 02
We Build the Case

Our team pulls comps, reviews CCAD 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 CCAD 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 CCAD. No contingency fee on your savings.

— Common Questions

What Collin 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 CCAD. We'll contact you if we need anything additional.
What's the deadline to file a protest in Collin 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 Collin 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.
