I had a business trip to a client in 2024 and I tacked on extra time because it was a nice place to be. I had a PO for up to 80 hours of support, so expected a solid two weeks, but things went better than expected and I only billed about half the time. Does the total days worked (including travel days) have to be at least 50% of the trip for any of the trip to be deductible?
More details: I had a condo and rental car for 4 weeks, but I was only at my client 2-4 days per week. Other things that made it less "work-like:" I had a weird flight itinerary with a few days' layover to make a social call, and my girlfriend stayed with me (didn't change the cost of the rental or the condo).
