Complete guide to appealing your DeKalb County property taxes in 2027. Beat the DeKalb County Board of Assessors with comparable sales evidence. Covers Decatur, Tucker, Stone Mountain, Dunwoody, and all DeKalb cities.
The DeKalb County Board of Tax Assessors uses mass-appraisal methodology to value all residential property in the county annually. Georgia law requires assessment at 40% of fair market value — meaning if your home's market value is estimated at $400,000, your assessed value should be $160,000, and your taxes are calculated on that figure. DeKalb County's diverse housing stock presents particular challenges for mass appraisal: intown neighborhoods with historic homes, midcentury ranch suburbs, newer construction in Dunwoody and Brookhaven, and rural pockets all require different valuation approaches. When the model applies broad averages to specific properties, errors are common — and most errors run in the assessor's favor.
Under O.C.G.A. § 48-5-311, you have exactly 45 days from the date on your Notice of Assessment to file an appeal with the DeKalb County Board of Tax Assessors. DeKalb County typically mails assessment notices between April and June. The 45-day window is strict — missing it means waiting until next year.
DeKalb County's intown neighborhoods — Decatur, Kirkwood, East Atlanta, Candler Park, Lake Claire — have seen significant appreciation driven by proximity to Atlanta employment centers and urban amenity demand. Meanwhile, outer DeKalb communities have had more modest growth. The county's mass-appraisal system struggles to capture this geographic variation accurately. Intown properties may be over-assessed due to model overreach; outer county properties may be over-assessed due to stale comparable data. Either way, if recent sales of comparable homes support a lower value, you have a strong appeal.
Georgia law provides several grounds for a property tax appeal. The most common and effective for residential homeowners is a fair market value appeal.
The DeKalb County Board of Tax Assessors responds to comparable sales evidence — recent sales of similar properties in your area that sold for less than the county's fair market value estimate for your property.
After filing your appeal, the DeKalb County Board of Tax Assessors will first conduct an internal review. If they offer a reduction you find acceptable, you can settle at this stage. If not, your appeal proceeds to the Board of Equalization — an independent three-member panel that holds a formal hearing and issues a binding decision. If you disagree with the BOE's decision, you can appeal further to Superior Court. TaxAppeal prepares letters structured to be persuasive at the initial BOA review stage, maximizing the chance of settlement without a formal hearing.

TaxAppeal USA is a self-service document-preparation service. We prepare a ready-to-sign appeal kit and mail it to you; you sign it and mail it to the county yourself. In every state we serve, including Florida, we are not property tax consultants, agents, or representatives, we do not provide tax or legal advice, and we do not file appeals or represent customers before any appraisal district, board of assessors, board of equalization, value adjustment board, or review board. Every appeal, protest and petition is prepared for the property owner, signed by the owner, and mailed by the owner in the owner’s name. In Florida your petition is signed by you as the property owner under section 194.011(3), Florida Statutes, and the county’s Value Adjustment Board filing fee is paid by you directly to the county. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
