What Records Support Business Travel And Vehicle Deductions?
For expenses subject to the stricter substantiation rules, you need records supporting the required details, such as amount, time, place, and business purpose. A card statement can establish payment without establishing why the expense qualifies. Vehicle use also needs a supported business-use calculation.
Capture The Explanation While It Is Still Fresh
Keep receipts with the trip or transaction details rather than collecting unexplained charges at year-end. A calendar, mileage record, invoice, and short business-purpose note can work together. Documentation requirements differ by expense, so use the rules that apply to the particular claim.
Separate The Expense Category From Deductibility
A well-documented expense can still be nondeductible or limited. Personal travel and ordinary commuting are not converted into business expenses by keeping receipts. Meals, gifts, and entertainment do not all have the same treatment; check the current rules before applying a single percentage to everything.
Make The File Understandable To Another Person
Someone who was not on the trip should be able to understand what happened and how the business portion was calculated. That is a useful practical test for your file, even before a preparer or examiner asks for it.
What To Gather Before The Conversation
- Receipts and proof of payment
- Dates, destinations, and business purpose
- Mileage or other use records
- Participants and business relationship where required
