FAQ
What counts as business miles?
Driving between work locations, to clients, to pick up supplies or to a temporary work site. Commuting from home to a regular workplace usually doesn't count.
What records do I need?
A log with date, purpose, start and end location and miles for each trip, kept as you go. A mileage log spreadsheet makes this easy.
