First year paying taxes in belgium

Hello guys,

It's my first year paying taxes in belgium and in any country to be honest.

So I really have no idea in what to do.

Can anyone recomend a good financial advisor or something that would help me file my taxes and give me advice?

I have no incomes or any possessions execpt my salary.

Is it possible to do everything online? I am working on a project abroad and it's quite hard to go to belgium.

Any advice is appreciated.
