Georgia IFTA Rates & Atlanta Freight Overview 2026

Georgia's diesel tax rate of 33.1 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.

Major Georgia Trucking Routes

I-75 (North-South): Tennessee border south through Chattanooga-area entry, Atlanta, Macon to Florida. Primary corridor for Southeast consumer goods and automotive freight.
I-85 (Northeast-Southwest): North Carolina/South Carolina border southwest through Atlanta to Alabama. Manufacturing corridor — textile and auto parts freight.
I-20 (East-West): Alabama border through Atlanta east to South Carolina. Major Atlanta distribution corridor for retail and consumer freight.
I-16 (Savannah Connector): Macon east to Savannah port. Critical container freight artery from Port of Savannah to inland distribution centers.
