Do I have to file Canadian taxes if I only arrived partway through the year?

Yes — if you established Canadian tax residency during the year by moving here with the intent to stay (on a work permit, study permit, or as a new permanent resident), you are a Canadian tax resident from your arrival date. You must file a T1 tax return reporting your Canadian income from the day you arrived to December 31, and your worldwide income before you arrived (even if not taxable in Canada) must be disclosed on Form T1161 if asked. Filing your first return triggers your eligibility for the GST/HST credit, Canada Child Benefit, and other government benefits — even if you owe no tax.

Do I have to report income I earned in my home country before arriving in Canada?

You must disclose your foreign income for the period before your arrival date on your first Canadian tax return — it is used to calculate income-tested benefits like the GST/HST credit and CCB. However, that pre-arrival foreign income is not taxed in Canada. Only income earned after your Canadian residency start date is subject to Canadian income tax. Income earned after arrival from foreign sources (a foreign employer, rental property abroad, investment income) is fully taxable in Canada, and you must report it each year.

What is a SIN and do I need one to file taxes?

A Social Insurance Number (SIN) is a 9-digit number issued by Service Canada that you need for work, tax filing, and accessing most government benefits. You should apply for your SIN as soon as you arrive in Canada — it is issued at a Service Canada office or online if you hold a PR card. If you are on a temporary work or study permit, you will receive a SIN beginning with 9, which is valid only while your permit is valid. If you cannot get a SIN before the tax deadline, you can request an Individual Tax Number (ITN) from the CRA instead — used only for tax purposes.

What is my "residency start date" for Canadian taxes?

Your residency start date is the date you established "significant residential ties" to Canada — typically the date you arrived with a long-term permit or as a permanent resident, opened a bank account, obtained a health card, and set up a home. For most newcomers, it is the date you physically arrived with the intent to stay. For people who moved back and forth, it can be a disputed question. When you file, you enter this date on the T1 jacket. All income from that date onward becomes subject to Canadian income tax.

Can I claim the GST/HST credit and Canada Child Benefit in my first year?

Yes. Simply filing your tax return automatically triggers the CRA's assessment for the GST/HST credit (paid quarterly) and the Canada Child Benefit (paid monthly, if you have children under 18). You do not need to separately apply once you file. For CCB, also complete RC66 (Canada Child Benefits Application) and ensure your children are registered on your tax file. Amounts are based on your part-year Canadian income plus your disclosed worldwide income from before arrival.
