Tennessee charges just 27.0˘ per gallon in diesel tax — one of the lowest in the Southeast. Calculate your TN IFTA liability and see why filling up before heading into Georgia or the Carolinas saves money.
Tennessee's diesel tax rate of 27.0 cents per gallon is one of the lowest in the Southeast — favorable compared to Georgia (33.1˘), North Carolina (36.1˘), and Kentucky (28.5˘). For carriers running I-40 between Memphis and Knoxville or I-65 between Nashville and Birmingham, Tennessee is the low-cost fueling state in the corridor.
Nashville and Memphis are two of the most strategically important logistics hubs in the US. Nashville sits at the intersection of I-40, I-65, and I-24 — within one overnight drive of over 65% of the US population. Memphis is home to the FedEx World Hub (the largest air cargo hub globally), the largest inland Mississippi River port, and a critical Class I railroad interchange — making it the busiest cargo node in the central US.
I-40 (East-West Spine): Arkansas/Memphis border east through Nashville, Knoxville to North Carolina. One of the highest-volume transcontinental freight routes — direct LA to East Coast corridor.
I-65 (North-South): Kentucky border south through Nashville to Alabama/Birmingham. Major automotive and consumer goods freight corridor.
I-75 (Northeast Corridor): Kentucky border through Knoxville, Chattanooga south to Georgia. Key Southeast manufacturing corridor connecting the Midwest to Atlanta.
I-24 (Nashville-Chattanooga Link): Nashville southeast to Chattanooga, connecting I-40 to I-75. Short but high-value manufacturing and distribution corridor.
