What you owe Maryland

IFTA apportions your fuel by miles. Divide total miles by total gallons for fleet MPG, turn your Maryland miles into taxable gallons, subtract the tax-paid gallons you bought in Maryland, and multiply by $0.4745.

Example: 1,000 miles in Maryland at 6.5 MPG is 153.85 taxable gallons. With 100 tax-paid gallons bought there, 53.85 × $0.4745 = $25.55 owed to Maryland.
