How do property taxes compare in Cumming vs Johns Creek in 2026?

Property tax bills differ between Cumming and Johns Creek mainly because they sit in different counties, Forsyth and Fulton, and each county along with its cities and school districts sets its own millage rate every year. The state assesses both at 40 percent of fair market value, so the gap comes from the rate applied locally, not the assessment method. Your county tax commissioner's office has the current rate for a specific address.
