As a homeowner in Clayton County, Georgia, understanding the difference between Fair Market Value (FMV) and Assessed Value is essential. These two figures directly affect how much you pay in property taxes each year. Here’s a clear breakdown of what they mean and how they apply to your property in Clayton County.
Definition: Fair Market Value is the estimated price your property would sell for on the open market between a willing buyer and a willing seller, with both parties having reasonable knowledge and no pressure to buy or sell.
How it’s Determined in Clayton County (and Georgia):
The Clayton County Board of Tax Assessors determines FMV annually.
This value reflects the property's condition and use as of January 1st of the tax year.
Valuation methods include:
Comparable sales of similar properties
Replacement cost (minus depreciation)
Income approach (for income-generating or commercial properties)
Definition: In Georgia, residential property is assessed at 40% of its FMV. This is the value used to calculate your property tax before any exemptions are applied.
Calculation in Clayton County:
Assessed Value = Fair Market Value × 0.40
Example:
If your home’s FMV is $250,000, your assessed value is:
$250,000 × 0.40 = $100,000
FMV is the starting point—it reflects what your home is worth on the market.
Assessed Value is the state-mandated percentage (40%) of FMV used to calculate your taxes.
After applying exemptions (like the homestead exemption), you get your taxable value, which is used to compute your final property tax bill.
If you believe your FMV is too high, you have 45 days from the date your annual assessment notice is issued to file an appeal.
A successful appeal reduces your FMV, which lowers your assessed value and ultimately your taxes.
Typical notice date in Clayton County: Mid-April
These reduce your taxable value, not your FMV or assessed value.
You must apply with the Clayton County Tax Commissioner’s Office by April 1st to receive exemptions for the current tax year.
Here’s the simplified formula used in Clayton County (and throughout Georgia):
Taxable Value = Assessed Value – Exemptions
Property Tax = Taxable Value × (Millage Rate ÷ 1,000)
Millage rates are set annually by:
Clayton County Board of Commissioners
Clayton County Board of Education
Your city (if applicable)
Issued each year—usually around mid-April
Includes both FMV and Assessed Value
