I am a British citizen, have been living and working in Brussels for almost five years now. I am married to a Belgian citizen, with two kids with Belgian nationality.
I am in the process of changing jobs. Until last week i have been a 'salarié', working in a Belgian based NGO. I am now likely to have a few consultancy roles, and am trying to figure out to best way to register, and am looking for advice!
I know that if I register as an independent in Belgium, I will end up paying a lot of tax, and the bureaucracy around registering seems relatively complicated. The other option is opening a UK based company (I still have family, bank accounts etc in the UK) and be paid through here - tax would be much less. That said, I am not sure of the impact that would have on things like la mutuelle, allocations familiales and things like this. Does anyone have any experience of this? Or any advice of who to speak to?
