While filing tax returns, I was asked, "Is this business effectively connected with the conduct of trade or business within the United States?" then I got a little confused.
I'm a US citizen working as a freelancer for the entire year in the US. I work with several clients and companies in foreign countries (e.g., selling a book on Amazon UK, working with an agency that provides services in France, etc.). I get paid to my US bank account.
Is my business considered effectively connected with conducting trade or business within the United States?
