When exactly did I become a resident of Canada for tax?
Residency begins on a date, and that date is a finding of fact rather than a stamp in a passport. It turns on when your life moved here: where you live, where your family is, what you signed and when. The date matters more than almost anything else on a first return, because Canadian tax starts on it, the credits you can claim are prorated to the part of the year after it, and the value of everything you already owned is fixed on it. So the first piece of work is establishing the date and keeping the documents that prove it.
Do I have to report income I earned before I arrived?
Canadian tax starts on the date your residency begins, so income earned before that date falls outside it. That does not make the earlier part of the year irrelevant. Your first return is a part-year return, and the credits available on it are prorated to the period you were resident, so the return has to show where the line falls and why. In practice the argument is almost never about the income itself. It is about the date, and about whether the documents you kept support the date you have used.
What happens to property I already owned when I moved to Canada?
Property you brought with you is treated as acquired at its value on the day your residency began. That is a reset, not a charge: nothing is taxed on arrival, but the cost base Canada will use for a later sale is that day's value rather than what you originally paid. Growth that happened before you arrived therefore sits outside the Canadian gain. The reset is only as strong as the evidence behind it, so the valuation work belongs at the start, while prices, statements and listings for that date can still be obtained.
Why are my tax credits lower in my first year here?
Because they are prorated. You were resident for part of the year, so the credits attached to being resident are apportioned to that part rather than granted in full. Nothing has gone wrong; a full-year claim on a part-year return is simply a claim the assessment will cut back. The practical consequence is that a first-year return often produces a smaller refund than the same figures would in a later year, and that it is worth knowing this before the return is filed rather than after a notice arrives.
Do I need to report my foreign accounts in year one?
Foreign-property reporting starts from the second year you are resident, not the first. It is the one genuine concession a newcomer gets, and it is easy to waste. The year of grace is the year to build the inventory: what you hold abroad, what it cost, what it was worth on your arrival date and which institution holds it. Do that while the papers are close to hand and the second-year filing becomes a transcription exercise. Leave it and you are reconstructing a foreign holding from memory long after the fact.
Can I claim child benefits before my first return is assessed?
Benefit entitlement runs from residency, so it does not wait on a filed and assessed return. A newcomer's claim is made on its own footing, using the arrival date and the household information available then. What matters is that the two pieces of work agree: the arrival date on the benefit claim and the arrival date on the first return have to be the same date, supported by the same documents. Where they diverge, the correction usually lands on the benefit side, and it lands as a recalculation of amounts already received.
How does the treaty tie-breaker work when both countries say I am resident?
As a sequence, stopping at the first test that gives an answer: where you have a permanent home available; if in both or neither, where your centre of vital interests is; then habitual abode; then nationality; and if all of those tie, the two tax authorities decide by agreement. It is evidential rather than elective — you do not choose your treaty residence, you demonstrate it, which makes the record of homes, family and time the substance of the claim. See tie-breaking dual residency.
How does cross-border tax planning work?
It starts with facts rather than structures: which countries have a claim on you, what each one taxes, and where the two overlap. From there the decisions are about order and timing — which country taxes first, where relief is claimed, and whether a filing or a certificate has to be in place before money moves rather than after. Most of the value is in the sequencing, because relief claimed late is usually relief recovered slowly. See international tax planning.
