What you owe Maine

IFTA apportions your fuel by miles. Divide total miles by total gallons for fleet MPG, turn your Maine miles into taxable gallons, subtract the tax-paid gallons you bought in Maine, and multiply by $0.3120.

Example: 1,000 miles in Maine at 6.5 MPG is 153.85 taxable gallons. With 100 tax-paid gallons bought there, 53.85 × $0.3120 = $16.80 owed to Maine.
