FAQ

When is the Denton County property tax protest deadline for 2026?

May 15, 2026, or 30 days after your Notice of Appraised Value was mailed by Denton CAD, whichever is later. Use the mail date printed on the notice.

How do I file a protest with Denton Central Appraisal District?

File online at appeals.dentoncad.com using the 4-digit eFile PIN on your notice, or submit Form 50-132 by mail (P.O. Box 50747, Denton, TX 76206), in person at 3911 Morse Street, or by fax to 940-349-3801. Keep confirmation receipts.

Should I check market value and unequal appraisal on my Denton CAD protest?

Yes when your evidence supports both. Selecting both grounds preserves options at informal review and ARB; you can still focus the hearing on the stronger argument.

Does Protestly file my Denton County protest for me?

No. Protestly generates a comparable sales evidence packet you can upload to eFile or bring to the appraiser. You remain in control of the protest and any hearing.
