The 2026 deadline is August 14, 2026. The window opens June 30, 2026. Clayton County states the 2026 Annual Notice of Assessments were mailed June 30, 2026, and that the last day to appeal is August 14, 2026.
Appeals are filed with the Clayton County Board of Tax Assessors, online, by mail, or in person. The governing jurisdiction is the Clayton County, 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.
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 Clayton County's own records at no cost. If there's no case, we'll tell you that too.
