Do you use public transport for your business ?
Train, streetcar, metro, bus 🚅 : 100% deductible as long as it's for a business trip. For VAT, you'll rarely get a proper invoice. However, for Belgian public transport, a tolerance exists: the 6% VAT is recoverable, even on the basis of a simple ticket !
💡 Journeys between home and work are considered private. Only business journeys are deductible. If you have a season ticket, it is therefore deductible up to the percentage of business use.
