Moved out of Portugal, how to deal with my NIF?

Hello everyone, so I  recently moved out of Portugal after living and working there for 5 months. I know that I got deregistered from my Portuguese address because I lived in a business apartment so my employer already took care of that but I am not so sure what I am supposed to do with my NIF. Ill not comeback to Portugal in few years because I am about to start a University in my home country and I dont want to be penalized for not canceling my NIF? I dont even know if thats a thing. I dont have any Portuguese income but I might start working in the Poland and I dont know how worldwide income tax works. Can someone help? Thanks :)

Why would you want to cancel your nif ? Keep it.
