Planning fuel costs in Mississippi
Track miles and MPG for a realistic gallons estimate; tax scales directly with gallons purchased.

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.
