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.
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.
Enter your address and we'll check DeKalb County's own records at no cost. If there's no case, we'll tell you that too.
