How property tax appeals work in Denton County

Every Texas homeowner has a right to protest their assessed value under Texas Property Tax Code §41.41. In Denton County, protests are handled by the Denton Central Appraisal District (Denton CAD). The deadline is May 15, 2026 — or 30 days after your appraisal notice was mailed, whichever is later.

Denton CAD allows email submission of protest evidence. Rapid growth in Flower Mound and Frisco-adjacent areas has caused consistent overassessment year over year.

The strongest protests include 3-7 comparable sales from the last 12 months in your immediate neighborhood, adjusted for square footage, age, and condition. Denton / Flower Mound-area assessors typically reduce values when presented with clear, recent comp data.
