How much of a mixed business trip is deductible?

Updated October 10, 2026 路 Schedule C, Line 24a
Short answer Schedule C, Line 24a Travel

A trip that mixed business and holiday belongs on Line 24a, travel.

Why line 24a

Inside the United States a mixed trip is split by two different tests, and that is what people get wrong. The transportation to and from the destination is all or nothing: if the primary purpose of the trip was business, the fare is fully deductible, and if it was personal, none of it is, with no proration either way. Everything at the destination is allocated instead, so lodging, local transport and the meals limit apply to the business days only. Days spent on business, days you traveled, and weekend days sandwiched between two business days normally count as business days.

Lodging on the business days is line 24a at full cost; meals on the business days are line 24b at 50 percent, and meals on the personal days are not deductible at all.

The limit that applies

Transportation within the United States is all or nothing on a primary-purpose test. Destination costs are allocated between business and personal days. Travel outside the United States follows separate allocation rules.

What to keep

Keep a day-by-day itinerary for the trip showing what was business on each date, and keep the underlying meeting or event proof. The day count is the whole calculation, so an itinerary written after the fact is the weakest point of the claim.
