How Property Taxes Work in Clayton County
The Clayton County Board of Tax Assessors estimates your home's fair market value as of January 1. Georgia then taxes 40% of that value, called the assessed value. Your bill is that assessed value, minus exemptions, multiplied by the combined millage rate of your county, city, and school district. One mill equals $1 of tax per $1,000 of assessed value.
School district taxes usually make up the largest part of a Clayton County bill. Under Georgia's statewide HOME ACT (Senate Bill 33), annual increases in a homestead's assessed value are capped to the rate of inflation.
Our median effective property tax rate (tax bill ÷ assessor's market value) accounts for exemptions and deductions, making it more accurate than the general median tax rate, which is the midpoint of statutory rates before adjustments.

What is the Median Effective Property Tax Rate?
Our median effective property tax rate (tax bill ÷ assessor's market value) accounts for exemptions and deductions, making it more accurate than the general median tax rate, which is the midpoint of statutory rates before adjustments.
Because Georgia taxes only 40% of market value, millage rates look high on paper, so the effective rate is the clearer comparison across Clayton County and the state.

How to Appeal Your Property Taxes in Clayton County
In Georgia, you can appeal if your county's fair market value is higher than what your home would sell for, if your home is assessed unequally compared with similar homes, or if you were denied an exemption.
Review your annual assessment notice
The Clayton County Board of Tax Assessors mails notices in spring or early summer. The notice lists your fair market value, 40% assessed value, and appeal deadline.
File within 45 days
Submit your written appeal to the Clayton County Board of Tax Assessors within 45 days of the notice date.
Choose your appeal route
Most homeowners choose the county Board of Equalization. Arbitration is also available, and certain higher-value properties can use a hearing officer.
Assessor review and hearing
The assessors may revise your value before a hearing. If you disagree with the revision, your appeal proceeds to the Board of Equalization.
Further appeal
If you disagree with the Board of Equalization, you can appeal to the Superior Court. If the appeal reduces your value, Georgia's 299c property tax freeze locks that value for the current year and the next two years unless the property changes substantially.
