Are Clarkston homes undervalued compared to DeKalb County?
Clarkston's lower median does not mean the county's assessment of your specific home is correct. Overassessments happen at every price point. Compare your assessed value per square foot to actual recent sales of similar homes nearby.
How is my Clarkston property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Clarkston's median home ($302,600), the assessed value is $121,040. Multiply by DeKalb County's millage rate of 4.379% to get your annual bill.

Comparing your value to 3-5 recent sales of similar homes is the quickest way to spot an overassessment.
Is it worth appealing a small overvaluation in Clarkston?
Yes. Even a $175 per year overcharge (from a $10,000 overvaluation at DeKalb County's 4.379% rate) adds up to $525 over three years with the 299c freeze. The appeal is free to file and there is no risk of your assessment increasing.
Why is my Clarkston property tax bill so high?
The median tax bill in Clarkston is $3,229 -- 124% above Georgia's statewide median of $1,439. This reflects both higher home values and DeKalb County's combined millage rate. If your individual assessment is higher than what your home would actually sell for, you are paying even more than necessary.
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.
