Georgia charges 37.3¢ per gallon in diesel tax (2Q 2026). Atlanta is the Southeast's top freight hub — calculate your GA IFTA liability.
Georgia suspended motor fuel tax from March 20 through June 2, 2026. For IFTA returns covering that period, Georgia has special reporting treatment: Georgia miles driven during the suspension are reported in Total Miles but excluded from Total Taxable Miles, and tax-free Georgia gallons are excluded from Tax-Paid Gallons. This calculator uses the Georgia miles you enter to estimate consumed gallons, subtracts your reported purchased gallons to calculate net taxable gallons, and applies the standard 37.3¢/gal 2Q 2026 matrix rate to that net amount. It does not identify or remove suspension-period activity, so the result can overstate taxable miles and gallons for that window. Manual treatment/review is required for any Georgia activity within that window.

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.
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.
