Attribution rule when sending cash from from USA bank account to Canada

[Gilgamesh]

As the title say, when we move cash from USA to Canada from bank to bank, how does attribution rule work?

Say this was a savings account funded over the years as a dual citizen in US over decades, and then when we become Canadian residents how does CRA know what’s attributed to whom?

How about even tIRA withdrawn into a us bank account as a US resident and then moved to Canada when residency changed, should one keep track of every dollar?

Or it doesn’t matter what happened prior to residency change? So when cash is moved, it can be attributed in any way?

I am asking as I am wondering how income splitting on interest earned in the Canadian bank for these transferred funds would work?

P.S: Of course, any tIRA withdrawal after Canadian residency will be reported in T1 for that year.

Thanks!

Anyone?

Say when I become a Canadian resident (Dual citizen) and move about $200k from USA bank/brokerage to a Canadian bank or brokerage account, could I just say all of that belongs to the lower social security recipient, so I pay taxes on interest/earnings under the lower social security recipients marginal tax rate ?

How about YOU finding the answer and letting US know. You've asked a hell of a lot of questions in 2 weeks. Call CRA.

I’m trying to find as many answers as possible before calling them. Thanks for answering the many questions.

Ask ONCE. No bumping.
