Multiply by Chatham County's millage rate of 3.371% to get your annual bill. Many Tybee Island homeowners find that assessed values have climbed faster than actual sale prices.

Why is my Tybee Island property tax bill so high?
The median tax bill in Tybee Island is $4,790 -- 232% above Georgia's statewide median of $1,439. This reflects both higher home values and Chatham County's combined millage rate.

Can my property tax go up if I appeal?
No. Georgia law (O.C.G.A. § 48-5-311) protects you: the county cannot raise your assessed value above what they originally set just because you filed an appeal. The Board of Equalization only rules on the disputed value. Worst case, your appeal is denied and you keep your current assessment -- your taxes will not increase as a result of appealing.
