How the appeal process works in Georgia

Georgia counties mail an Annual Notice of Assessment, and an appeal must be filed within 45 days of the notice date (O.C.G.A. §48-5-311). Appeals go to the county Board of Assessors and, if not resolved there, to the Board of Equalization — most settle on the evidence, and Georgia allows remote hearings. A successful appeal freezes the reduced value for the two following tax years (O.C.G.A. §48-5-299(c)), so one appeal can lower the bill for three.

Can an appeal raise my assessment?

Yes, it's possible — a Georgia Board of Equalization may increase, decrease, or sustain an assessed value on appeal (O.C.G.A. §48-5-311). That's why we check for that exposure before filing: we don't file when we see it, and if it surfaces after filing we withdraw. We'd rather lose the case than leave you worse off than when you started.
