Ohio charges 47.0¢ per gallon in diesel tax. Calculate your OH IFTA liability and plan fuel stops in Kentucky (28.5¢) before heading north — saving $28 per fill on a 150-gallon tank.
Ohio's diesel tax rate of 47.0 cents per gallon places it in the mid-tier range — lower than Pennsylvania (74.1¢) and Indiana (55.0¢) to the east and west, but higher than Kentucky (28.5¢) and West Virginia (35.7¢) to the south. For north-south runs on I-75 or I-71, the optimal fueling point is the Cincinnati, KY area before crossing north into Ohio.
Ohio sits at a critical crossroads for US freight: the I-75 corridor between Florida and Michigan passes through Dayton and Toledo; I-71 connects Cincinnati, Columbus, and Cleveland; and I-80/I-90 runs east-west along the northern border. The Ohio Turnpike (I-80/90) adds per-axle toll costs on top of the IFTA fuel tax for northern routing between Indiana and Pennsylvania.
I-75 (North-South): Kentucky border through Dayton, Toledo to Michigan. Major automotive corridor — carries more auto parts freight per mile than nearly any US interstate.
I-71 (Diagonal): Kentucky border through Cincinnati, Columbus, Cleveland. High-volume consumer goods and parcel freight corridor.
I-70 (East-West): Indiana border through Columbus east to Pennsylvania. Central Ohio cross-country freight route.
I-80/I-90 (Ohio Turnpike): Indiana border east through Cleveland to Pennsylvania. Separate per-axle toll costs apply — I-80 through southern Ohio offers a toll-free east-west alternative.
