If you're self-employed, your deductible miles depend on where your self-employed business is located. If you maintain an office at home, all your miles are typically deductible from your "office" to any place business related. You have no commuting in this instance.
If you operate your business from somewhere other than your home, you can't deduct the miles you drive from home to your first business-related stop. They are commuting miles and therefore, not deductible. Of course, you can deduct driving costs from your business location to the bank, a client's office, etc.
