text: do i pay taxes in canada or us? i did very little work when i was in the us now i am back in canada and i was wondering since i am doing my taxes in canada this month can i add the jobs i did in the us in it? i was living and working overseas but always passing through canada to visit my folks and take long breaks.. a little like what i am doing now. you need to see if you are required to file a fed return. go to irs.gov in the key words box type in filling requirements.if you don't have to file a us return than don't. but if you pd in taxes you might want to so you can get the money you pd in back! i don't know if canada wants all the income you made or not.you will have to find out
