Georgia Property Tax Assessed Value: 40 Percent of Fair Market Value

Georgia property tax assessed value is 40 percent of fair market value. Official O.C.G.A. math, millage, and why a protest argues FMV—not the ratio.

FAQ

Is Georgia property tax assessed value 40 percent of fair market value?

Yes for most real property. Official assessment level under O.C.G.A. § 48-5-7 is generally 40 percent of fair market value. Fulton, Gwinnett, Cobb, DeKalb, and the other Georgia counties we cover use that statewide ratio—not a local percentage.

Do I protest the 40 percent ratio or the fair market value?

You protest fair market value (and uniformity among similar parcels). After FMV is set, the county applies 40 percent to reach assessed value, then millage and exemptions. The Board of Equalization does not repeal the statutory ratio.

Why is my neighbor’s tax bill lower if we both use 40 percent?

Different FMV conclusions, homestead or senior school exemptions, and city vs. unincorporated millage can change the bill with the same assessment level. Compare FMV, assessed value, and exemptions—not tax dollars alone.

Does Protestly file my Georgia assessment appeal?

No. Protestly builds a $29.99 print-ready comparable sales packet you can attach to PT-311A and present yourself. We do not file or appear at BOE.
