Kansas diesel tax rate is 26.0¢ per gallon for 2026. Calculate your quarterly IFTA fuel tax liability for Kansas routes and compare to neighboring states.
Kansas at 26.0¢/gal is a solid fueling value at the crossroads of the nation. I-70 across Kansas is one of the longest uninterrupted stretches of interstate in the country and handles a massive volume of cross-country freight. Kansas City on the eastern border is a top-5 US freight market and one of the most important rail-truck transfer points in North America.
I-70 (Topeka–Salina–Hays–Colby–Colorado, primary east-west), I-35 (Kansas City–Wichita–Oklahoma City), I-135 (Salina–Wichita, north-south connector), US-54 (Liberal–Wichita–Missouri)
Wichita is the state's second-largest freight market, driven by aviation manufacturing (Boeing, Spirit AeroSystems, Cessna) and agriculture. Kansas wheat harvest (June–July) creates significant seasonal demand for bulk and flatbed carriers. Neighboring Oklahoma to the south offers the nation's second-lowest rate at 19.0¢, making southbound fuel stops worthwhile on I-35.
