🔴 2026 Protest Deadline: May 15, 2026 — or 30 days after your Notice of Appraised Value is mailed, whichever is later. Miss this date and you waive your right to protest.

Collin County has seen some of the most dramatic property value increases in the Dallas-Fort Worth metroplex. Cities like Plano, Frisco, McKinney, Allen, Prosper, and Celina have drawn corporate relocations, new development, and rapid population growth — and appraisal values have followed. That growth is real. But the appraisal district’s numbers don’t always reflect market corrections, and too many property owners simply pay what they’re billed without questioning it.

You have the right to protest. In 2023, more than 115,000 Collin County properties were protested — and owners who did protest saved an average of nearly $1,975 per account. The tools below are your starting point.

How to Protest Your Collin County Property Taxes

1

Look Up Your Value

Search your account at collincad.org. Know your Notice of Appraised Value and the deadline printed on it.

2

File Your Protest

File online at Collin CAD’s e-Services portal, by mail, or in person at 250 Eldorado Pkwy, McKinney, TX 75069. Deadline: May 15, 2026 or 30 days after mailing.

3

Gather Your Evidence

Recent sales of comparable homes, your purchase price, photos of property condition issues, and repair estimates all support your case.

4

Try Informal Resolution

Before your ARB hearing, a CAD appraiser may offer to settle informally. Review any offer carefully — you can accept or proceed to the formal hearing.

5

Present to the ARB

The Appraisal Review Board is independent of the CAD. Present your evidence clearly and concisely. Most hearings last 15–30 minutes.

6

Appeal If Needed

Disagree with the ARB ruling? You may appeal to district court, binding arbitration, or SOAH (properties over $1 million).

“No person’s particular services shall be demanded, nor property taken or applied to public use, unless by the consent of himself or his representative, without just compensation being made therefor.”

— Section 13, Declaration of Rights, Republic of Texas, 1836

Collin County is one of the wealthiest, fastest-growing counties in America. It is also one of the most aggressively taxed. The founders of this Republic were explicit: property is not to be taken without consent and just compensation. Show up. Look up your value. File your protest. Attend the hearings. The people setting these rates are your neighbors. They work for you — as long as you hold them to it.
