Why DeKalb appeals are time sensitive: DeKalb County typically mails annual Notices of Assessment in late spring, with most notices arriving between mid-May and early June. You have 45 days from the date printed on your notice to file an appeal with the DeKalb County Board of Tax Assessors. The clock starts the day the notice was mailed, not the day you received it. Miss it and your assessment stands for the year. AppealAlly tracks DeKalb deadlines automatically and pre-fills the PT-311A so you can file before the 45-day window closes.

Why Appeal in DeKalb County

  • Strong reduction outcomes. Across Metro Atlanta counties, including DeKalb, the historical track record on residential property tax appeals is favorable: 82.2% of Gwinnett County appeals reached a reduction in the 2025 tax year (source: Gwinnett County Board of Assessors FOIA release), and DeKalb operates under the same Georgia statute.
  • Three-year freeze. Under O.C.G.A. section 48-5-299(c), when a Board of Equalization, hearing officer, arbitrator, or Superior Court reduces your value through a formal appeal, DeKalb cannot raise that value for the appeal year plus the next two successive years.
  • No risk if you lose. Filing an appeal cannot raise your assessment. If you don’t win a reduction, your existing value stands. HB 581 (effective January 1, 2025) only attaches the 3-year freeze when an appeal produces an actual reduction, so there’s no penalty for trying.
  • No filing fee. Filing the PT-311A with the DeKalb County Board of Tax Assessors is free at every stage of the appeal, including the Board of Equalization hearing.
