Fulton County
property tax, explained.
A Fulton assessment notice is not the final property tax bill. Check the taxable assessment and exemption for each taxing authority, then apply that authority’s bill-year millage.

From market value to assessed value to millage
A hypothetical $300,000 fair market value becomes $120,000 assessed value at 40%, before exemptions. With no exemption for this example authority and a hypothetical 20-mill rate, tax is $120,000 ÷ 1,000 × 20 = $2,400. If an approved exemption lowered that authority’s taxable value to $100,000, its tax would instead be $2,000.
Annual tax for one authority at its entered millage. Excludes other authorities, temporary-billing adjustments, credits, fees, penalties and interest. No homestead eligibility is assumed.

The estimate on the assessment notice can use older rates
The Board of Assessors FAQ explains that assessment notices use previous-year millage to estimate taxes. A notice’s estimate therefore does not establish the final rate for the new bill.
Compare the property’s fair market value, assessed value, exemption information and tax year separately. The Georgia Department of Revenue’s example shows the 40% assessment step and millage calculation. This tool starts after the assessment and applicable exemption steps.
Read the date printed on your assessment notice
The county FAQ describes a 45-day appeal window. Use your notice’s date and the current appeal instructions to determine the actual filing deadline. Keep the parcel identifier, disputed value and supporting evidence with your submission.
Do not treat the date you happen to open the envelope as the start of a new window. An exemption application and a valuation appeal address different questions; check which request you need before using the online service.
An unresolved appeal can still produce a payable bill
The appeal page explains temporary billing while an appeal remains unresolved and says the temporary bill must be paid to avoid penalties and fees. A pending case is not a general payment holiday.
The one-authority calculator does not reproduce a temporary-billing adjustment or remaining balance. For those questions, the county appeal page directs readers to the Tax Commissioner at 404-613-6100. Compare the issued statement, payments and subsequent adjustments instead of paying only a calculator estimate.

The calculator divides the taxable base by 1,000, multiplies by the entered rate and rounds to cents. It is a bill-checking tool, not an official tax determination. Other site tools may use different benchmark assumptions.
