General education only, not legal advice. Confirm the date on your notice and with Denton Central Appraisal District (Denton CAD).
How the Denton County deadline works
Texas law sets the protest deadline as May 15 or the 30th day after the notice of appraised value is delivered, whichever is later (Tax Code 41.44). The Texas Comptroller's protest page tells owners to count 30 days from the date the appraisal district mails the notice. When the deadline lands on a weekend or legal holiday, it moves to the next business day (Tax Code 1.06). That is why 2027's date is Monday, May 17.
The date printed on your own notice is the one that controls. If your notice went out late, your 30 days may run past May 17. File well before either date.
2027 dates to put on your calendar
- January 1, 2027: valuation date. Your 2027 value reflects the market on this day.
- April 2027: Denton CAD usually mails Notices of Appraised Value. Your notice carries the PIN for online filing.
- Monday, May 17, 2027: the usual deadline, because May 15 is a Saturday. A later date on your notice wins.
- Late May through summer: settlement offers, informal reviews and Appraisal Review Board hearings. The ARB must give at least 15 days' written notice of your hearing.
One date people mix up with this one: the 2026 tax bill is due Monday, February 1, 2027. That is a payment deadline, not a protest deadline. Filing a protest does not move it.
How to file before the deadline
- Online. File at eprotest.dentoncad.com with the PIN on your notice. The portal also lets you upload evidence, see the evidence Denton CAD plans to use, and accept or decline a settlement offer. Our walkthrough: how to file a Denton CAD protest online.
- Paper. Mail or drop off Comptroller Form 50-132 at Denton Central Appraisal District, 3911 Morse St., Denton, TX 76208. The phone number is 940-349-3800. If you mail it close to the deadline, keep proof of the mailing date.
Check both grounds on the form: value over market value, and value unequal compared with other properties. You can file first and add evidence later. Save your confirmation.
Make sure Denton CAD is your district
City limits and county lines don't match up here. Thousands of homes with a Frisco, Carrollton, Prosper, Plano or Celina address sit in Denton County and are appraised by Denton CAD, not Collin CAD or Dallas CAD. The deadline rule is the same statewide, but the portal, PIN and mailing address are not. The district named at the top of your notice is the one you file with. See which appraisal district covers your address.
If you miss it
You can file a late protest with a written statement of good cause before the Appraisal Review Board approves the appraisal records. The ARB decides whether to accept it. Do not count on it. Our too-late guide explains the exceptions.
