Meals, Travel & Business Expense Substantiation: A Business Purpose Is Not Enough Without the Right Documentation

Deductibility and substantiation are separate questions. Business purpose, amount, time, place, attendees, travel status, reimbursement, and record quality should be preserved.

A legitimate business purpose does not eliminate the substantiation rules for meals, travel and entertainment-related expenses. The practitioner should separate deductibility, percentage limitations and documentation.

Travel requires tax-home analysis

Overnight business travel generally depends on being away from the taxpayer’s tax home. Indefinite work assignments, commuting and itinerant work patterns can change the result.

Meals require business context and current limitations

Business meals may be subject to percentage limitations and must satisfy business-purpose rules. Entertainment expenses follow separate rules even when food is purchased at the same event.

Section 274 demands specific evidence

Amount, time, place and business purpose—and business relationship where required—should be documented. Estimates and credit-card statements alone may not establish the necessary facts.

Mixed-purpose trips need allocation

A trip combining business and personal days can require allocation, and international travel can involve additional rules. Family-member travel generally needs its own business justification.

Reimbursement does not fix missing documentation

An accountable-plan reimbursement requires substantiation. Set receipt, mileage and business-purpose procedures before travel occurs.

Planning takeaway

A business purpose is necessary, but documentation makes the deduction defensible.

Identify the tax home, separate meals from entertainment, allocate mixed travel and preserve §274 evidence contemporaneously.
