Collin County Property Tax Protest

Collin County has spent a decade as one of the fastest-growing places in America, and its appraisal roll shows the strain: aggressive year-over-year increases, new-construction values set above what buyers actually paid, and land revaluations that jump entire neighborhoods at once. All three are protestable. You only pay if we lower your taxes.

How protests work at the Collin Central Appraisal District

Appraisals here come from the Collin Central Appraisal District at collincad.org, covering Plano, Frisco, McKinney, Allen, Prosper, Wylie, Celina, and the county's smaller towns. The deadline follows the standard Texas rule — May 15, or 30 days after your notice is delivered, whichever is later — and filings go through the district's online portal or by mail.

Collin CAD runs informal reviews before Appraisal Review Board hearings, and well-supported residential cases often settle there. The district's models lean heavily on the county's huge volume of recent sales — which cuts both ways, because that same sales data is exactly what a good protest uses against an inflated number.

The fast-growth problem — and why it favors you

In a county building this fast, mass appraisal has a lag problem. Builders' premium lots and upgrade packages get baked into neighborhood averages, so the base-model home next door inherits value it doesn't have. First-year owners routinely get notices above their own closing price — and a settlement statement is about the strongest protest evidence there is. Meanwhile, in the established Plano and Allen neighborhoods, land revaluations can push a flat-market house up double digits in a single year. Each of these calls for a different argument, and we pick the one the evidence supports.

Collin County questions we hear

My appraisal is higher than what I just paid for the house. Is that normal?

It's common in Collin County, and it's very fixable. Your closing statement is direct evidence of market value on or near January 1 — usually the single best exhibit a protest can have. Recent buyers are among our strongest cases.

I just bought — when does the 10% homestead cap start protecting me?

The cap begins after the first full tax year with your homestead exemption in place, so your first assessment is uncapped — which makes protesting that first number especially important. It becomes the base every future cap year builds on.

My city is Frisco — is my property in Collin or Denton county?

Frisco straddles the county line, so it depends on where the parcel sits. Your appraisal notice says which district issued it; whichever side you're on, we handle it — the Denton County side is covered here.
