Property taxes
Property taxes represent an important source of revenue for Gwinnett County. More than one-third (34.1 percent) of the total revenue for all operating funds and nearly three-quarters (71.5 percent) of the revenues for the tax-related funds are derived from property taxes. The amount of property tax revenue is based on the size of the tax digest and the millage rate.

The tax digest is the total value of all property subject to taxation as determined by the Tax Assessor. Property in Georgia is assessed at 40 percent of the fair market value, unless otherwise specified by law. The economy, as well as state and local policies, impact the size of the net digest.

Gwinnett enjoyed a growing digest for many years. As a result, county government was able to roll back the millage rate, provide property tax relief, and still have increasing revenues to meet community needs. The digest condition looked good as it had continued to show increases year after year. But by 2008, this year-over-year digest growth slowed down, and by 2009, the digest had lost value. This loss in value was the result of housing and economic conditions (namely, increased foreclosures, decreased construction, and the freeze in assessments). The last year of tax digest decline was 2013; since that time, the digest has shown a modest recovery as home prices are beginning to recover and construction is increasing.

The amount of property tax revenue is also based on the tax rate (or millage rate), which is set annually by the Board of Commissioners. The Board of Education and the governing authority of municipalities also establish tax rates based on the property values. A tax rate of one mill represents a tax liability of $1 per $1,000 of assessed value. These rates are the amount required to fund planned expenditures divided by the net digest.



How property tax is calculated
The average fair market value for a home in Gwinnett County was $200,000 in 2017. Fair market value is the amount a knowledgeable buyer would pay for the property and a willing seller would accept for the property at an arm’s length, bona fide sale. Assessed value is 40 percent of the fair market value.

Formula to calculate property tax for a home with a fair market value of $200,000:
Annual Property Tax = [(40% x Fair Market Value) - Exemptions] x Millage Rate
Annual Property Tax = [(.40 x $200,000 ) - Exemptions] x Millage Rate
Annual Property Tax = $80,000 - Exemptions x Millage Rate
