Mark Kohler breaks down the 2025 mileage deduction: $0.70 per mile for trips between business locations. Only drives to vendors, customers, or supply sources count. You need a home office as your starting point, so a trip from home to the Apple Store to pick up an iPhone qualifies.

The rule for writing off auto mileage. And I love auto mileage because it's $0.70 per mile this year. In 2025, that's a big deal. But it has to be between business locations or your business office to go visit a vendor or go visit a customer or go pick up supplies. Well, by definition, I need to have a starting and an ending point. For example, I went to the Apple Store to go pick up a new iPhone. Well, I'm going to the Apple Store, but where did I start? Where's the beginning mileage point? Well, when I have a home office, that gives me the starting point. If I have office across town, then that's where I would start from there. This is why the home office deduction is so important, because I need to have a beginning and ending point in order to track mileage.
