Georgia Property Taxes Explained

Property taxes are the primary funding mechanism for local government services in Georgia — schools, roads, public safety, and county administration all depend on them. For property owners, understanding how the tax is calculated, what exemptions may reduce it, how the assessment and appeal process works, and what happens if taxes go unpaid is essential knowledge for managing the ongoing cost of property ownership.

How Georgia Property Tax Is Calculated

Georgia uses an ad valorem property tax system — meaning taxes are based on the value of what a person owns. The calculation follows a consistent three-step process.

First, the county Board of Tax Assessors determines the property's fair market value — what the property would sell for in an arm's-length transaction between a willing buyer and willing seller. Assessors use various methodologies including comparable sales, income capitalization for investment properties, and replacement cost analysis.

Second, the assessed value is calculated at 40% of the fair market value. This is Georgia's statutory assessment ratio, applied uniformly across the state. A property with a fair market value of $300,000 has an assessed value of $120,000 for tax purposes.

Third, any applicable exemptions are subtracted from the assessed value to arrive at the taxable value. The remaining taxable value is then multiplied by the applicable millage rate to determine the tax owed.

The millage rate is the local property tax rate expressed in mills — one mill equals $1 of tax per $1,000 of taxable assessed value. If a jurisdiction's millage rate is 15 mills, the tax on $100,000 of taxable value is $1,500. Millage rates vary by county and differ further within counties based on which school district, municipality, or other taxing district the property falls within.

Who Sets the Millage Rate

Multiple taxing entities can levy property taxes on the same parcel — the county government, the county school district, the municipality if the property is within a city, and sometimes special taxing districts. Each jurisdiction sets its own millage rate annually based on its budgetary needs and projected revenue from other sources. The total millage rate applied to a given property is the sum of all jurisdictions' rates.

Georgia's Statewide Property Tax Assessment Notice

Each year, property owners receive an annual notice from the county Board of Tax Assessors showing the assessed value of their property. This notice includes both the current year's assessed value and the prior year's value for comparison, and it specifies the deadline for filing an appeal if the owner disputes the assessment.

Exemptions That Reduce Property Taxes

Georgia law provides several property tax exemptions that reduce the taxable value of a property.

The standard homestead exemption reduces the assessed value by $2,000 for county and school taxes on a property owner's primary residence, per O.C.G.A. § 48-5-44.

Individuals 65 and older with household income below a specified threshold may claim an additional $4,000 exemption from all county ad valorem taxes.

Additional age- and income-based exemptions are available at the county level, and many Georgia counties offer substantially more generous homestead exemptions than the statewide minimum. Some counties freeze the assessed value of a homestead for qualifying senior residents, preventing increases in the taxable value regardless of market appreciation.

Veterans and surviving spouses of veterans who died in service or as a result of a service-connected disability may qualify for additional exemptions, with some fully disabled veterans receiving complete property tax relief on their primary residence.

All exemption applications must be filed with the county by April 1 of the tax year. Exemptions must be based on the property owner's status as of January 1 of the same year. Once approved, most homestead exemptions renew automatically as long as the owner continues to occupy the property.

Where and When to Pay Property Taxes

Real property taxes are paid to the Tax Commissioner in the county where the property is located. Personal property taxes are payable in the county of the property owner's residence. Due dates vary by county but typically fall around December 20 of each year. Late payments trigger penalties and interest that accumulate quickly, and continued non-payment can eventually result in a tax lien on the property and ultimately tax sale.

Appealing a Property Tax Assessment

If a property owner believes the county has overvalued their property, they have 45 days from the postmarked date of the Notice of Assessment to file a written appeal with the Board of Tax Assessors. Appeals may be based on taxability, value, uniformity of assessment, or denial of an exemption.

The written appeal must identify the chosen method of appeal: a hearing before the Board of Equalization, binding arbitration, or — for commercial properties in some cases — an appeal to a hearing officer. If the appeal is not resolved before tax bills are mailed, the owner is required to pay a temporary bill equal to 100% of the proposed assessment, 85% of the proposed assessment, or the prior year's tax — whichever the owner elects — while the appeal proceeds.

A final decision by the Board of Equalization or arbitrator can be appealed further to the Superior Court.
