For those of us who drive our personal calls for business - there is a huge tax benefit provided by Uncle Sam - standard mileage tax deductions. ExpressMileage is really cool because it makes a complete mileage log for a year after you answer a few questions. This saved me $13k in taxes last year. The logs created are IRS compliant and can be edited easily. Using this website, you can quickly create mileage logs for a week, month, quarter or year. Perfect for those sale reps, ride sharing drivers, delivery drivers or anyone else who drives a lot for their work and needs to get reimbursed or have tax deductions.
