What you owe Kansas

IFTA apportions your fuel by miles. Divide total miles by total gallons for fleet MPG, turn your Kansas miles into taxable gallons, subtract the tax-paid gallons you bought in Kansas, and multiply by $0.2600.

Example: 1,000 miles in Kansas at 6.5 MPG is 153.85 taxable gallons. With 100 tax-paid gallons bought there, 53.85 × $0.2600 = $14.00 owed to Kansas.
