For context, I am a Spanish citizen currently studying in a university in Denmark (I am doing the full degree there. It is not an Erasmus or any other exchange program.), as part of this studies I am doing an internship in a german company in Germany (that's where I am living right now). Once the internship I will be moving back to Denmark to continue with my studies.
I have been offered a remote working student position (part time) at the company where I am currently doing the internship. The contract that I have been sent states the address that I have now in Germany, but by the time to contract takes effect I will no longer have that address. Because, as I understand, I will have to deregister from my current address once I move back to Denmark after the internship is over.
With that in mind, I would like to know:
- Is that possible/legal?
- Where would I have to pay taxes, for this job?
- Do I need to keep my german insurance?
- -Can I keep my german bank account (that's where I will get paid)?
