I'm wondering if you need a VAT/BTW number in Belgium
for money you could earn by doing one or both of the following:
- Creating an Android/IOS app (free time) and
sell it
- Earn
ad revenue
(e.g. Admob) through ads on your own website/apps.
Or does this all depend on the amount you earn? E.g. if it would be less as € 500,00 a year.
