What you owe Michigan

IFTA apportions your fuel by miles. Divide total miles by total gallons for fleet MPG, turn your Michigan miles into taxable gallons, subtract the tax-paid gallons you bought in Michigan, and multiply by $0.5240.

Example: 1,000 miles in Michigan at 6.5 MPG is 153.85 taxable gallons. With 100 tax-paid gallons bought there, 53.85 × $0.5240 = $28.22 owed to Michigan.
