Collin County

We protest in all of Collin County.

Texas Tax Lock handles property tax protests for homeowners throughout Collin County, including Plano, McKinney, Frisco, Allen, Wylie, Murphy, Fairview, Lucas, Anna, Celina, Princeton, Lavon, Josephine, Nevada, and Prosper. Collin County has been the fastest-growing county in the country by population and remains one of the most competitive real estate markets in Texas.

The Collin Central Appraisal District (CCAD) appraises all property in the county. The extraordinary growth Collin County experienced from 2018 to 2023 pushed home values — and CCAD appraisals — to levels that now frequently exceed what the current market will support. That gap between assessed value and true market value is exactly what a well-built protest can correct.

The statutory deadline to file a protest with CCAD is May 15, 2026. We handle the filing, evidence development, and all informal and formal hearing representation. Sign up today and we take it from there.

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 CCAD 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 CCAD'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 CCAD 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 Collin County homeowners ask us.

What is CCAD and how does it affect my property taxes?
CCAD — the Collin Central Appraisal District — appraises all real and personal property in Collin County for ad valorem tax purposes. The values CCAD sets each year are used by Plano ISD, Frisco ISD, McKinney ISD, Allen ISD, and other taxing entities to calculate your annual property tax bill. If CCAD's assessed value for your property is higher than what comparable sales evidence supports, a formal protest is the legal path to reduce it — and that's 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.
Are Collin County appraisals more aggressive than other DFW counties?
Collin County's growth rate has been extraordinary, and CCAD has been aggressive about tracking appreciation. In years of rapid price growth, CCAD often appraises at or near full market value — and sometimes above what the evidence supports. This makes comparable sales analysis especially powerful: if similar homes in your neighborhood sold for less than your assessed value, Texas law requires CCAD to correct the discrepancy. We pull those comps from CCAD's own records and from MLS databases, so the evidence is hard to dispute.
