Property Tax Appeals in DeKalb County, Georgia
DeKalb's standard 2026 Annual Notice of Assessment appeal window closed around July 13, 2026 for typically-timed notices. An owner whose notice was mailed later, or who received a corrected notice, still gets 45 days from that mailing date to deliver a written appeal to the Board of Tax Assessors. The filing should identify the parcel, state the grounds, give the owner's value assertion, and select one appeal avenue. DeKalb offers a free Board of Equalization route, non-binding arbitration for valuation disputes, and a hearing officer for qualifying non-homestead property over $500,000. The county currently lists a $217 arbitration filing fee and requires a certified appraisal for that route. This is an appeal of assessed value, uniformity, taxability, or an eligible exemption decision, not a protest of millage rates or the amount of a tax bill. FairPath's owner-guided evidence packet remains available year-round, while the owner verifies, signs, files, and manages the county proceeding.
Assessment context: DeKalb appraises real property annually at fair market value as of January 1 and applies Georgia's 40 percent assessment ratio. Start with the county property-search profile and notice: verify parcel ID, address, owner, land and improvement values, building area, year built, class, exemptions, sales history, and the notice date. DeKalb's official explanation identifies sales comparison, cost, and income as its three valuation approaches and says its CAMA system considers sales, permits, property characteristics, zoning, and land use. That matters in a county ranging from dense Decatur and Atlanta-area neighborhoods to established suburban subdivisions and larger eastern parcels. A nearby sale may still differ in municipality, school context, construction, renovation, lot utility, or access. Keep fair market value, 40 percent assessed value, exemptions, and estimated tax in separate columns.
Filing process: For online filing, locate the parcel, enter the last eight digits of the ten-digit access code from the notice, complete the prompts, and retain the final confirmation page or email. DeKalb warns that high traffic or portal failure does not extend the 45-day period. A mailed appeal letter should include parcel ID, property address, daytime phone, reason for appeal, supporting documents, and the selected avenue: Board of Equalization, hearing officer, or non-binding arbitration. An agent needs written authorization. DeKalb does not accept appeals by fax or email. A timely appeal may be postmarked by the U.S. Postal Service or hand-delivered by the deadline under the county instructions. Preserve the notice, signed submission, exhibits, postal proof or stamped copy, and confirmation number. Choosing a route has procedural consequences and possible fees, so read the current form before filing.
Evidence to review: Build evidence around the ground checked on the DeKalb appeal. For value, use arm's-length sales near the January 1 valuation date and explain differences in location, living area, lot, age, quality, basement, renovation, condition, and transaction circumstances. For uniformity, compare the assessment treatment of genuinely similar parcels rather than tax bills. Dated interior and exterior photographs, inspection findings, contractor estimates, permit history, or records of functional problems can explain condition that mass appraisal data may not capture. Correct objective facts with the official property profile and supporting measurements or documents. A recent purchase can be documented with the settlement statement and sale circumstances. Arbitration currently requires a certified appraisal at the owner's expense and a $217 filing fee; it is not simply another free hearing. Index every exhibit by source and date, connect it to the owner's asserted value, and keep the exact packet filed with DeKalb.
Current deadline guidance: Standard 2026 window closed ~July 13; a later or corrected notice keeps its own 45 days. DeKalb requires a written appeal within 45 days of the date on the parcel's Annual Notice of Assessment. DeKalb's Tax Commissioner's office has publicly stated the 2026 deadline as July 13, consistent with the county's typical late-May/early-June mailing cycle -- that standard window has closed. A parcel with a later-issued or corrected notice still gets its own 45 days from that later mailing date; the notice is the controlling record for any such parcel. A failed online attempt does not extend the period, so use a permitted delivery method before the applicable deadline.
DeKalb's online appeal requires the notice access code, and the county expressly says portal unavailability does not extend the 45-day deadline.
The free Board of Equalization is a three-member panel of trained DeKalb property owners independent from the appraisal department; arbitration and hearing-officer eligibility differ.
DeKalb's current appraisal office is at 325 Swanton Way in Decatur, which is the address identified for mailed and hand-delivered appeal materials.
The county annually values property as of January 1 at fair market value and reports assessed value at 40 percent, so evidence should address the correct value date and value lane.
