Ohio IFTA Rates & Trucking Overview 2026

Ohio's diesel tax rate is 47.0 cents per gallon (2Q 2026).

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.
