This is our main tax information forum which deals with topics concerning Canadians living and working in the U.S., U.S. citizens contemplating working in Canada, and all aspects of Canadian and U.S. income tax and related adminstrative issues.
I'm reading publication 519 for the first time and seeing a 30% tax associated with non-US source income for non-residents. I'm filing a 1040NR. Does this mean I have to report any Canada-source income and pay 30% tax on it?
