Georgia IFTA Rates & Atlanta Freight Overview 2026

Georgia's diesel tax rate of 37.3 cents per gallon is one of the better rates in the Southeast — lower than Florida (36.2¢) and North Carolina (36.1¢), but higher than Tennessee (27.4¢) and Alabama (28.5¢). For north-south runs through Atlanta, fueling in Chattanooga or Dalton, TN before entering Georgia is the optimal play.

Atlanta is without question the most important freight distribution hub in the Southeast. I-75 and I-85 merge through Atlanta in the Downtown Connector — one of the busiest sections of interstate in the country. The Port of Savannah, accessible via I-16 from Macon, is the third-largest container port in the US by TEU volume and among the fastest-growing. Georgia carriers should budget for Atlanta's notorious congestion costs (idle time, detention) in addition to IFTA.
