Working simultaneously in USA and Canada

[TaxMess 0]

Hi,

Thank you for your help in advance. I am about to enter into a potentially complicated tax situation and wanted to make sure my understanding is broadly correct.

The situation:
UK Citizen resident in USA currently going through AoS
Working 2 days a week in Canada (staying overnight in Canada)
Working 3 days a week from home in the USA

As I understand it I will pay Canadian income tax on the portion of income earned in Canada (being 2/5) and have to file a Canadian income tax return. I will not be tax resident in Canada due to 183 day rule and ties to USA and hence won't have to declare worldwide income.

I will also have to file a US tax return on which I will declare world wide income (including Canadian income) I will be able to apply a tax credit for Canadian tax paid against federal tax but which for my state NJ will not be credited against state tax.

Anything I am missing?

You're a UK citizen. Do you have any requirement to pay UK income tax on foreign income?

Regards,
Bill

As I have relocated to USA and will be working abroad I would expect to qualify for split year treatment in Y1 and therefore not have to pay income tax on foreign earnings.
