I am doing my taxes for the 1st yr in US (TN1)
Please tell me if the senario below is correct?
If my income in USD = 50,000 and Paid US tax = 10,000 USD (only income, no ties)
It means that I eraned 50,000x1.25= 62.500 CND and paid 12,500 in CND
But accoding to CRA, if I earned this much in Canada I would have paid 18,000 CND tax.
So, now I have to pay the difference of 5,500 CND to Canada

2nd question:
If I owe US 1000 more, how can I proof it to CRA? CRA just asked me to send them my W2 as the proof of income.
Thanks
