Flights

VAT deductibility: n/a (usually, there is no VAT on flights)

TAX deductibility: 100%

Flying to a conference, a client or another destination for professional purposes?
Your ticket is deductible for income tax (usually, there is no VAT on flights). Tickets for your partner, who travels with you to visit the country, are of course non-deductible.
Combining a business trip with a pleasure trip? You only deduct the airplane tickets that concern the professional part of your trip.

Belgian Public Transport

VAT deductibility: typically 100%

TAX deductibility: 100%

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).

Foreign Public Transport

VAT deductibility: 0% (Reverse charge may apply)

TAX deductibility: 0% (Reverse charge may apply)

All tickets for train, subway, tram and bus trips outside Belgium.

Taxi

VAT deductibility: typically 100%

TAX deductibility: 75%

You can deduct a taxi trip as long as, as always, you can prove the professional link: a taxi to the airport for a business trip is fine, a taxi back after dinner... does not work!
You get 75% back for income tax, 100% for VAT (if you have a valid invoice with your own VAT number).
Good news is that Uber is considered a taxi in terms of deductibility. The good thing? They can provide proper invoices.

Hotels

VAT deductibility: 0%

TAX deductibility: 100%

Hotel fees must be: (i) necessary for business reasons, (ii) not to be unreasonable and (iii) If your other half travels with you, those costs are not deductible.
The daily allowances (for directors) that you grant yourself during your stay abroad for professional purposes are 100% deductible.
Any restaurant costs, if clearly stated on the hotel bill, are 69% deductible for income tax and are generally not deductible for VAT.

Other Travel Expenses

VAT deductibility: typically 100%

TAX deductibility: 100%

If you are travelling abroad for purely professional purposes, for example for training or prospecting, you deduct your transport and accommodation.
If you are self-employed in a company, you may be able to deduct per diems, a lump sum that covers e.g. your food and other expenses, under certain conditions.
If you are self-employed as a natural person, per diems do not apply. You can deduct professional expenses, with supporting documents as usual.

They always answer right away to any question I have, they provide clear answers, and they are very patient even when I struggle to understand. They try to explain in different ways. They are very helpful, responsive and friendly.

In the world where everyone seems to be out to get small entrepreneurs and overwhelm them with new rules, more taxes and reporting obligations, Accountable often feels like the one steady partner that actually wants you to succeed, providing quick, clear and personalised support. Thank you!

This program is a lifesaver, and it is always improving. Plus, it has an AI chat feature that is actually useful.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful. Combined with the AI I never feel alone with Accountable.

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.

They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
