You have various reasons to travel as part of your business activity 🧳: visiting a client, attending a congress or seminar, visiting a trade fair or an event related to your profession (the Milan Biennale for an architect, for example).

For the expense to be deductible, you must prove the professional nature of the trip. Keep, for example, photos, emails, names of business contacts on site, seminar registrations, brochures... This applies to expenses such as: flights and hotels, public transport or taxis and car rentals.

If I am a company director, am I entitled to a flat-rate allowance for my on-site expenses? Yes! In this case, there is no need to keep your receipts (food, drinks, local transport, etc.). Pay for everything with your personal account and submit an expense report to your company. This will include the daily flat-rate allowances (see the FPS website for more information on Per Diem rates by country) that you can claim for each day of your assignment on site. Also consider your arrival and departure days. Here is also a more detailed article on the subject.

💡 If you are a company director, submit an expense report including the Per Diem flat-rate allowance for each day of your trip. Unfortunately, this is not possible for sole proprietorships.
