Public transport

Train, tram, metro, bus: everything is good!
In terms of deductibility, public transport is an excellent option!
They are fully deductible (if the journey has a professional purpose, of course)

Note that the VAT on train tickets is 6%, but you will not necessarily see it indicated as such, the price of the SNCB ticket being inclusive of VAT.

In general, public transport companies are exempt from the obligation to issue users with an invoice for the delivery of tickets (tickets, cards, subscriptions). To recover VAT, your ticket will therefore be sufficient (this is an exception to the rule of proper invoices). Note that many accountants and even tax auditors don’t know this rule.
