Gwinnett County property tax is higher than average for the Atlanta metro area. Gwinnett County property tax rates aren't as high as DeKalb County and aren't as low as Cobb County. For the tax year 2012 the Gwinnett County government did not raise the millage rate. However, for 2013 some tax rates will rise and some will fall within Gwinnett County, Georgia. As reported by the Atlanta Journal-Constitution back in November, based on the settlement of a lawsuit between Gwinnett County and the incorporated cities within it, real estate owners within unincorporated Gwinnett County will see a tax increase, while those in incorporated areas may see an increase or a decrease, depending on how many County services they use.
