General Information

Ad valorem taxes, more commonly known as property taxes, are levied for the maintenance and operations of the City. Property taxes are also levied for certain public improvements funded by voter approved general obligation debt (bonds). The basis for ad valorem taxation is the fair market value, as determined by the Fulton County Board of Assessors. The tax is levied on the assessed value of the property which is established at 40% of the fair market value (unless otherwise specified by law). The amount of tax is determined by the tax millage rate.

The City of Alpharetta Finance Department is responsible for the billing and collection of property taxes for our municipality and relies solely on the Fulton County Board of Assessors for tax information that pertains to property owners, fair market and assessed values, and property/billing addresses.

Millage Rate and Taxpayer Savings

The City’s millage rate for 2023 (fiscal year 2024) is the same as the prior year at 5.750 mills and includes 4.951 mills for general government (operations and recurring capital) and 0.799 mills for debt service on voter approved bonds.

A history of the City’s millage rate levy can be found on our Financial Transparency Portal.

Residential Tax Reduction Through Homestead Exemptions

The City provides multiple homestead exemptions that save our homeowners over $8.8 million annually and goes great lengths in keeping Alpharetta an affordable place to live and raise a family.  The State of Georgia is providing an additional $1.1 million in property tax savings to our homeowners through the Homestead Tax Relief Grant (HTRG) Credit.  Detailed information on our Homestead Exemption offerings and HTRG Credit can be found HERE.
