What counts as business driving
- Usually deductible: driving to customers and job sites, picking up supplies, going to the bank or post office for the business, and traveling between work locations.
- Not deductible: commuting from home to your regular place of business, and personal errands.
If your home is your main place of business, trips from home to customers and suppliers usually count. Ask your tax professional about your situation.
Tips for an audit-ready log
- Log trips on the day you drive them. Records made at the time are much stronger than estimates later.
- Write a clear business purpose, such as "Estimate for the Lopez kitchen", not just "Work".
- Save favorite trips for regular routes, like the supply store, so logging takes seconds.
- Download your log regularly; it’s stored only on this device.
