Get your taxes done using TurboTax

If I understand your question correctly, you will file your Canadian return based upon US tax withholding, but not tax actually paid, since you will file a US extension and therefore not file a Form 1040 until after April.

 

The actual US tax liability will be less than the amount claimed on the Canadian return. I am not a Canadian tax expert but you would have to amend your Canadian return if the amounts reported change.
