Planning fuel costs in Missouri
Track miles and MPG for a realistic gallons estimate; tax scales directly with gallons purchased.
Diesel, aviation gasoline, and dyed fuel follow different federal and often different state schedules.
For tax-deductible business miles, use the IRS standard mileage rate or actual expenses—gas tax is already embedded in fuel cost and is not a separate personal income-tax line.
