DeKalb County, GA

Appeal your DeKalb County property assessment

2026 assessment cycle. Updated July 8, 2026.

DeKalb County's 2026 property tax appeal deadline is on or before July 13, 2026. If your home is over-assessed, you file Form PT-311-A with the DeKalb County Board of Tax Assessors. Filing is free, and this page covers the steps.

The 2026 deadline

DeKalb County mailed 2026 assessment notices on May 29, 2026, and Georgia law gives you 45 days from the mailing date to appeal (O.C.G.A. 48-5-311). That puts the county deadline at July 13, 2026.

The clock runs from the mailing date printed on your own notice. If your notice shows a different date, your date plus 45 days governs. There are no extensions; the next chance after the window closes is the 2027 notice.

Where to file

File Form PT-311-A with:

DeKalb County Board of Tax Assessors
Property Appraisal Department
325 Swanton Way
Decatur, GA 30030

DeKalb also accepts appeals online and in person. On the form, choose the Board of Equalization (BOE) as your appeal method. The BOE route is free and hears every ground you can raise.

How the appeal works

Georgia counties appraise your home at fair market value each year and compute the tax on 40 percent of that value (O.C.G.A. 48-5-7). An appeal challenges the fair market value itself.

There are two independent grounds: the value is higher than the market supports, or your assessment is out of line with comparable homes (uniformity, O.C.G.A. 48-5-311). Either can lower your bill, and one appeal can claim both.

The DeKalb County Board of Tax Assessors reviews your appeal first. If it isn't resolved there, it goes to a Board of Equalization hearing automatically. The hearing is informal and built for homeowners.

A successful appeal generally locks the resulting value in place for three years (O.C.G.A. 48-5-299(c)), so a reduction won in 2026 holds through 2028.
