Just did a 1040NR for a client to recoup about 18k in taxes witheld on gambling winnings...and the ONLY reason we filed the 1040NR is that gambling winnings are not taxable in Canada....making the exercise worthwhile...


What you might consider though is simply filing Canadian returns, which you'll have to do anyway because you are taxed on your worldwide income....and claim the US taxes as a tax credit...meaning Canada recognizes that the tax has already been paid to the US....which will reduce your Canadian tax bill....


You likely still have to file a 1040NR...but it would be a "nil return" stating the income is only taxable in Canada...simple, and if you're paying someone, much less costly....








If writing ever becomes work I think I'm going to have to stop
