What you owe Arkansas

IFTA apportions your fuel by miles. Divide total miles by total gallons for fleet MPG, turn your Arkansas miles into taxable gallons, subtract the tax-paid gallons you bought in Arkansas, and multiply by $0.2850.

Example: 1,000 miles in Arkansas at 6.5 MPG is 153.85 taxable gallons. With 100 tax-paid gallons bought there, 53.85 × $0.2850 = $15.35 owed to Arkansas.
