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, 2027, 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.
Denton County is one of the counties in our Texas Over-Assessment Study, where we ran millions of homes through the same unequal-appraisal comparison the Denton CAD uses. You can check your own address free in 30 seconds, or read our full methodology first.
