Serving All of Dallas County

Texas Tax Lock handles property tax protests for homeowners across Dallas County, including Dallas, Irving, Garland, Mesquite, Richardson, and Duncanville. With a population of approximately 2.6 million, Dallas County is served by the Dallas Central Appraisal District (DCAD).

Dallas County homeowners saw an average 12% jump in appraised values in 2026. DCAD is one of the most active appraisal districts in Texas — protests here are common and frequently successful.

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 DCAD before the deadline.

STEP 02
We Build the Case

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

— Common Questions

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