Frequently Asked Questions

What is Georgia's property assessment ratio?

Georgia law requires property to be assessed at 40% of its fair market value. So a home worth $250,000 has an assessed value of $100,000. The millage rate is then applied to this assessed value to calculate the tax. Source: Georgia DOR, dor.georgia.gov/property-tax-valuation (June 2026).

How is property tax calculated in Georgia?

Annual Tax = (Assessed Value − Exemptions) × (Mill Rate / 1,000). Assessed Value = 40% of Fair Market Value. For example, a $250,000 home with a 25-mill rate and a $2,000 standard homestead exemption: assessed = $100,000; taxable = $98,000; annual tax = $98,000 × 0.025 = $2,450.

What is Georgia's standard homestead exemption?

Georgia provides a $2,000 state homestead exemption on assessed value for primary residences. Many counties offer additional local exemptions. The homestead exemption does not apply to school levies at the state level unless additional exemptions are granted by the county or school board. Source: Georgia DOR (June 2026).

When must I file for homestead exemption in Georgia?

You must file with your county tax commissioner or board of assessors by April 1 to receive the exemption for the current tax year. Once filed for your primary residence, it automatically renews. Source: dor.georgia.gov (June 2026).
