Denton County

We protest in all of Denton County.

Texas Tax Lock handles property tax protests for homeowners throughout Denton County, including Denton, Lewisville, Flower Mound, Corinth, The Colony, Highland Village, Little Elm, Argyle, Aubrey, Sanger, Krum, Cross Roads, Bartonville, Roanoke, Justin, and Ponder.

The Denton Central Appraisal District appraises all real property in the county. Denton County absorbed much of the northward DFW expansion over the last decade, driving sharp appreciation in cities like Flower Mound, The Colony, and Little Elm. Denton CAD has tracked that growth aggressively — which creates strong protest opportunities for homeowners whose assessments exceed what comparable sales support.

The deadline to file a protest with Denton CAD is May 15, 2026. We file the protest, pull the comparable sales and unequal appraisal data, and handle all informal and formal hearings. You do nothing except sign up.

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 DCAD 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 DCAD'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 DCAD 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 Denton County homeowners ask us.

What is Denton CAD and how does the protest process work there?
Denton CAD — the Denton Central Appraisal District — appraises all property in Denton County for tax purposes. The values they set each year are used by Denton ISD, Lewisville ISD, Frisco ISD (for Denton County portions), and other taxing entities to calculate your tax bill. Your Notice of Appraised Value comes from Denton CAD. The protest process starts with filing before May 15, followed by an informal hearing with a CAD appraiser, and then a formal ARB hearing if the informal doesn't resolve. We handle every step.
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.
Is Denton County still growing enough to affect my appraisal?
Denton County growth has moderated from its peak but the appraisal district's assessed values often lag market corrections. This creates a window: if sales of comparable homes in your area came in below your assessed value, you have strong grounds for a protest. The unequal appraisal argument is also highly effective in Denton County — if similar homes nearby are assessed lower than yours on a per-square-foot basis, Texas law requires that to be corrected. We analyze both grounds and pursue whichever yields the better result.
