Tie-breaking dual residency in practice — how much of this can I do myself?
Some of it, yes — and we will say so on the call if that is the honest answer. The parts that are worth paying for are the ones where a missed election, a missed deadline or an unverified threshold costs more than the fee: the tie-breaker applies its tests in order, so the case is built around the first test that resolves it.
What if I have already filed and got it wrong?
That is a common starting point. We re-derive the position, identify whether an amendment or a disclosure route is the right vehicle, and tell you which one preserves the relief that is still available. The order matters more than the speed.
How long will it take?
It depends on the documents rather than on us. Once the pack is complete most filings turn around inside a fortnight; anything that needs a certificate from a tax authority runs on that authority's timetable, which we tell you at the start rather than at the end.
Both countries say I am tax resident, which one wins?
Neither, until the treaty tie-breaker is applied to your facts. Each country reaches its own conclusion under its own domestic rules, and those rules can both be satisfied at once, which is what dual residence means. The treaty then resolves it by applying a series of tests in a fixed order, and the case stops at the first test that produces an answer. That ordering is what makes the analysis practical: if the first test resolves your position, the later ones are irrelevant and arguing them muddies the file. So the work is to identify which test decides your case, and then to evidence that test properly rather than to assemble everything about your life.
What documents prove where my centre of vital interests is?
The ordinary records of where a life is actually lived, kept at the time. Leases and property documents, school registrations for children, medical coverage and appointments, where the family sleeps on ordinary days, bank and utility records, club and professional memberships. None of these is conclusive on its own; together they describe a settled pattern. What does not work is a statement written years later asserting where your interests were centred, because that is an assertion about the past made by the person who benefits from it. The documents are persuasive precisely because they were created for other reasons at the time.
Does keeping a house in the country I left make me resident there?
Having a permanent home available to you in a country is one of the tests, and keeping a property can keep that test live, but it does not settle the matter by itself. Where a home is available in both countries, the analysis moves to the next test in the order, which looks at where your personal and economic relations are closer. So the house matters as a fact in a sequence rather than as an answer. What matters as much is what the property is actually used for, whether it is let out on ordinary commercial terms, and whether your possessions and your family are there.
What happens if the tie-breaker tests do not resolve my residence?
Where the facts are genuinely balanced and the ordered tests do not produce an answer, the route is to ask the two tax authorities to settle it between themselves under the competent authority procedure, rather than to take a position on one return and a contradictory position on the other. That is a deliberate step with its own process and its own evidencing requirements, and it produces a residence determination rather than an argument repeated annually. It is the right answer in a genuinely balanced case. It is the wrong answer where one of the ordered tests would have resolved the case if the evidence had been assembled.
Can I be treaty non-resident and still have to file a tax return?
Yes, and the two questions should be kept apart. A tie-breaker outcome allocates residence for the purposes of the treaty; it does not switch off a domestic filing obligation, and in many cases the treaty position is something you assert on a return rather than instead of one. There may also be income that remains taxable in the country you are treaty non-resident in, because the treaty gives it a taxing right over that source. Settle residence first, then work through what each country may tax, then decide what has to be filed where. Skipping the middle step is what produces inconsistent returns.
My family stayed behind when I moved for work, am I still resident there?
Where the family remains is one of the strongest facts in the test that looks at personal and economic relations, and it often decides a case on its own. It is not decisive in every case, because the test weighs personal and economic ties together and a move can shift the economic side substantially. But be realistic about how the file reads: a home maintained and a family living in it describes a continuing centre of life, and the evidence on the other side has to be correspondingly strong. If the intention is to break residence, the arrangement of the family is the fact that needs addressing first.
Is foreign pension income taxable in Canada?
Yes. A Canadian resident reports foreign pension income in Canadian dollars like any other income, and foreign tax withheld on it becomes a credit rather than a reduction of the amount reported. Where a treaty exempts part or all of it — some social security pensions are treated this way — the relief is claimed as a deduction on the return, not by leaving the pension off. Omitting it and claiming it was exempt are two very different filing positions. See the pensions and annuities article.
What is a "dual-status alien spouse", and why is my software asking?
The question comes from the filing-status screens, and it is asking whether your spouse was a non-resident or part-year resident for the year — because if they were, a joint return is not available by default. An election exists to treat a non-resident spouse as a resident for the whole year, which unlocks joint filing at the price of bringing their worldwide income into the US return and their accounts into its reporting. See a US person with a non-resident spouse.
