Wisconsin IFTA Calculator

Wisconsin is the dairy capital of the United States and a major manufacturing and agricultural freight state in the upper Midwest. I-94 runs east-west from the Illinois border through Milwaukee, Madison, Eau Claire, and on to the Minnesota border near Hudson — this is the primary Chicago-to-Twin Cities freight corridor. I-90 runs east-west through the southern portion from Beloit through Madison and La Crosse. I-43 runs north-south from Beloit through Milwaukee to Green Bay. Milwaukee's port on Lake Michigan handles break-bulk and heavy cargo, and Green Bay is a major paper and food processing center.

Wisconsin's IFTA rate of $0.329 per gallon is moderate. Minnesota at $0.285 to the west is cheaper. Iowa at $0.325 to the southwest is similar. Illinois at $0.463 to the south is dramatically more expensive, making Wisconsin a favorable fueling state before heading south on I-90 or I-94 into Illinois. Michigan at $0.272 to the east is cheaper. For carriers running I-94 between Chicago and Minneapolis, fill up in Wisconsin before the Illinois border — the $0.134 per gallon difference between Wisconsin and Illinois saves $20.10 on a 150-gallon fill.

Standard weight limits are 80,000 lbs on interstates. Wisconsin has extensive spring weight restrictions — the state maintains a network of Class A, B, and C roads with different weight limits during the spring frost thaw period from approximately February through May. Dairy tankers and agricultural equipment haulers are the primary users of county and state routes with these restrictions, and rural dispatchers must monitor WISDOT's posted restriction schedule closely.

Weigh stations on I-94 near the Illinois border at Beloit and near the Minnesota border at Hudson are active. For IFTA compliance, Wisconsin's Department of Revenue processes IFTA filings through their My Tax Account portal — the moderate rate and clear corridor structure make quarterly filings straightforward, with the main complexity being accurate mileage capture during the agricultural harvest season when routes deviate from major interstates.
