Deductible if you can prove a business connection
Among cab and car rental costs 🚕 you'll also find short-term car rental (Avis, Sixt, Europcar,...), carpooling (BlaBlaCar, Cambio,...) and VTC (Uber, Heetch,...).
If you take a cab from the station to a customer's home, is it tax-deductible? Yes, up to 75%. VAT, on the other hand, is 100% recoverable, but for this to be the case, you need to have a proper invoice (which includes your VAT number).
💡 Online services like Uber, Blablacar,... allow you to download invoices.
