What is the deadline to grieve my Roswell property tax assessment in 2026?

Fulton County uses the word appeal rather than grievance, and the 2026 deadline for a Roswell property is stated on that year's annual assessment notice, calculated from its mailing date rather than a set calendar day. Missing that window means waiting until the following year's notice to try again. The Fulton County Board of Tax Assessors can confirm the current date if your notice was misplaced. Joel can help pull comparable sales while you still have time to file.
