Minnesota IFTA Calculator

Minnesota is the freight hub of the Upper Midwest, with Minneapolis-St. Paul serving as the distribution center for the region. The Twin Cities sit at the convergence of I-35 (running north-south from Kansas City to Duluth), I-94 (running east-west from St. Paul to Fargo), and I-90 (running east-west across the southern portion of the state from South Dakota to Wisconsin). The Port of Duluth on Lake Superior is a major grain, coal, and iron ore shipping terminal, and the highway corridors feeding it — US-53 and US-2 — are essential to Minnesota's mining and agricultural freight. The Red River Valley along the North Dakota border is some of the most productive wheat and sugar beet farmland in North America.

Minnesota's IFTA rate of $0.285 per gallon is moderate. North Dakota at $0.230 to the west is cheaper. Wisconsin at $0.329 and South Dakota at $0.280 are in a similar range. Iowa at $0.325 is somewhat higher to the south. Illinois at $0.463 is the stark comparison point for southbound I-90 or I-35 drivers — fill up in Minnesota or Iowa before entering Illinois.

Minnesota has strict weight laws and enforces them aggressively. The state uses portable weigh scales extensively on state highways in addition to fixed stations. Seasonal weight restrictions on secondary roads are some of the most extensive in the country — spring thaw restrictions run from roughly February through mid-May on many county roads and state highways. Agricultural haulers get limited exemptions during harvest but must still comply with posted limits.

Winter in Minnesota is severe — I-90 and I-94 closures during blizzard conditions are common from November through March. The Blatnik Bridge connecting Duluth to Superior, Wisconsin has weight restrictions and height limits for commercial vehicles. For IFTA compliance, Minnesota's Department of Revenue runs a reliable online filing system — the main challenge is tracking mileage accurately during the agricultural harvest season when carriers may run many miles on county roads not captured by GPS routing systems.
