Moving (temporarily) abroad while keeping Belgian domiciliation?

Hi all,

I live and work in Gent and have Belgian nationality. Since I move to Gent ~7 years ago I have always been registered at the domicile where I lived and the rule was always "you need to register your new domicile as soon as you move".

I now have a job that allows me to work remotely although the contract is in Belgium so I'm forced to have some sort of residence here, as far as I understand I need to keep my fiscal residence here.

My question is what are the options to stay within the law (i.e keeping my fiscal residence in Belgium ) while moving temporarily abroad. In practice I've read that you can move physically out of the country and you will still be considered fiscal resident of Belgium as long as you spend aprox. half of the year here. How does this go in practice, do I need to keep my domicile somewhere here too? My plan is to stop my current rent, move a few months abroad and then come back and set my domicile somewhere else. Is there any problem with this? leaving the current domicile but not setting a new one for a few months? I know I can set some postal domicile for post and such but my concern is with my fiscal status and any possible effect on my work contract.

Hope someone has any idea or starting point on where to find out more about this. Just to be clear I want to stay of course within the law, keep paying taxes and all, just want to know the bureaucratic process.

Enjoy!
