Roth IRA Calculator

Can Canadians Open a Roth IRA?

No. A Roth IRA is a US retirement account. Opening one requires US earned income and a US tax filing obligation: so a Canadian resident without US tax status cannot have one.

If you have come across the term through US financial media, books or podcasts, that is common. Roth IRAs are heavily covered in American personal finance content, and the concept translates: it is just that the account does not.

Canada's equivalent is the Tax Free Savings Account, and it is a close structural match.

If you are a US citizen or green card holder living in Canada, or you moved here holding a Roth IRA you opened while working in the US, your situation is different and considerably more consequential. That is covered from the section on taxation onwards.

Is a Roth IRA Taxable in Canada?

This is where the stakes rise, and the answer depends entirely on whether you filed one election.

Without the election, Canada treats the account as an ordinary investment account: interest, dividends and capital gains accruing inside it are taxable annually on your Canadian T1 return at your marginal rate, whether or not you withdraw anything.

The account stays tax free in the US under IRC §408A. It simply is not in Canada.

At top combined marginal rates, that is roughly:

Years of US tax advantaged growth, reversed by a change of residence: unless the election is filed.

With the election in place and no disqualifying contributions, Canada respects the Roth character: growth is not taxed annually, and qualified distributions are generally tax free in Canada as well as the US.

What the Election Letter Must Contain

Per CRA Folio S5 F3 C1. Verify against the current folio before relying on this list:

If you hold more than one Roth IRA, the election must cover each account: with these details repeated for each.

If You Have Missed the Deadline

A missed deadline is not necessarily the end of it.

The CRA folio directs questions about late filed elections to the Competent Authority Services Division, and at least one cross border practitioner reports confirmation that late elections are being accepted: provided the election has not already been tainted by a Canadian Contribution.

So the ordering matters:

• Missed the deadline but never contributed after moving? A late or protective election may still be possible. Raise it with a specialist promptly.
• Contributed after becoming a Canadian resident? That portion is permanently outside treaty protection, regardless of when you file.

Either way, this is a conversation with the Competent Authority through a cross border tax professional, not something to attempt alone. Always verify the current late filing position before taking action.

T1135 and Foreign Reporting

A useful piece of relief that is under communicated.

If the election has been made and no Canadian Contribution has been made, no T1135, T1141, T1142 or T1134 reporting is required for the Roth IRA.

That matters, because a Roth IRA would otherwise potentially fall within the CAD $100,000 specified foreign property threshold that triggers T1135 filing.

Traditional IRAs and 401(k)s

These are treated differently from Roth accounts, and generally more simply.

Growth inside a traditional IRA or 401(k) is generally not currently taxable in Canada, and no annual election is required. Tax applies when you take a distribution, reported as pension income on your Canadian return.

Withholding on distributions: the default rate on retirement plan payments to foreign payees is 30%, reduced to 15% for periodic pension payments under the treaty, with valid documentation on file. Canada grants a foreign tax credit for US tax paid, so the same dollars are not taxed twice: but the sequencing matters and the paperwork has to be right.

Roth 401(k) plans carry the same tainting exposure as Roth IRAs and need the same care. Always verify current withholding rates and documentation requirements with your tax professional.

Converting Before You Move

A planning question with a window that closes on arrival.

Converting a traditional IRA to a Roth while still a US resident means paying US tax on the conversion at US rates.

Doing it after becoming a Canadian resident makes it a Canadian Contribution, which taints the Roth. And distributions from the traditional account taken as a Canadian resident face Canadian marginal rates, which at the top end run above 53% in several provinces.

One published scenario illustrates the gap: converting before moving at a 24% US federal rate, split across two tax years while resident in a state with no income tax, against Canadian rates reaching 53.5% in British Columbia on later distributions.

Whether that trade makes sense depends entirely on your circumstances: the size of the account, your US and Canadian marginal rates, your timeline, your state of residence before moving, and what else is happening in the year of departure.

This is exactly the kind of decision to model properly with a cross border specialist before you move, because afterwards the option is gone.

Getting Proper Advice

We would rather be direct about this than pad the page with reassurance.

Cross border tax is specialist work. The election is irrevocable, the deadline is fixed, the tainting rule is permanent, and the consequences of getting it wrong run to tens of thousands of dollars over the life of an account.
