Taxes for Newcomers to Canada: What to Expect in Your First Year

Moving to Canada is a fresh start — and filing your first Canadian tax return is part of settling in. The good news: Canada's tax system is not designed to punish newcomers. In fact, filing a return often unlocks benefits — the GST/HST credit, the Canada Child Benefit, the Ontario Trillium Benefit — that put real money back in your pocket. The complication is that your first year involves a part-year resident return that covers two different periods, two different income universes, and sometimes two countries' worth of paperwork.

This guide is written for individuals who established Canadian tax residency during the year — permanent residents, temporary foreign workers with significant residential ties, and others who became tax residents of Canada as newcomers living in Ontario.

When Do You Become a Canadian Tax Resident?

You do not automatically become a Canadian tax resident the day you land. You become a tax resident when you establish significant residential ties to Canada — typically when you move into a home, bring your family, and begin your settled life here. For most newcomers, this is arrival day or shortly after.

The date matters because Canada taxes you on worldwide income from the date of arrival only — not on income you earned in your home country before you came. Your first return is called a part-year resident return covering the period from your arrival date to December 31.

Income Before Arrival: What Gets Reported?

Income earned in your home country before your arrival date is generally not taxed in Canada. You do not report it on your Canadian T1 return. However:

• You may need to disclose it if it affects your adjusted cost base (ACB) of assets you brought to Canada
• If you received certain payments after arrival but for pre-arrival work, special allocation rules apply
• Your home country may still tax the same income — a tax treaty between Canada and your home country determines whether a credit is available for taxes paid abroad

The Bump-Up in Cost Base: Your Fresh Start on Assets

One of the most valuable newcomer rules is the deemed acquisition rule: when you become a Canadian tax resident, you are deemed to have acquired all of your property at its fair market value on your arrival date. This is the reverse of departure tax (which deems you to have sold everything when you leave).

Practically, this means:

• Investments you bring to Canada get a "stepped-up" cost base equal to their fair market value on arrival day
• Capital gains that accrued before you came to Canada are generally not taxed by Canada when you eventually sell
• Your real estate in your home country (if you keep it) also gets this stepped-up cost base

Documenting the fair market value of your assets on arrival day is therefore very important — get written valuations, keep brokerage statements dated as close to arrival as possible, and retain real estate appraisals.

Filing Your First Canadian Return: Key Points

Reporting Worldwide Income from Arrival

From your arrival date forward, you report your worldwide income to Canada. This includes:

• Canadian employment income (reported on a T4 slip)
• Business or self-employment income earned from arrival
• Rental income from any property anywhere in the world
• Investment income (interest, dividends, capital gains) from anywhere in the world
• Foreign pension or employment income received while you were a Canadian resident

The T1 General and Your Province

Ontario residents file a federal T1 return with Ontario provincial tax calculated on Schedule ON. Ontario has its own rate structure, and Ontario's provincial benefits (Ontario Trillium Benefit) are applied through the same return.

Your SIN Is Your Starting Point

You need a Social Insurance Number (SIN) to file a return. If you arrived on a temporary permit, you may have received a SIN beginning with a "9" — these are temporary SINs. You can still file a return with it.

Benefits Newcomers Can Claim

Filing a return — even if you owe nothing — is essential to access these benefits:

• GST/HST Credit — a quarterly payment for low-to-moderate income individuals; available from the quarter following your arrival date
• Canada Child Benefit (CCB) — a tax-free monthly payment for families with children under 18; significant in amount, verify current rates with CRA
• Ontario Trillium Benefit (OTB) — combines the Ontario Energy and Property Tax Credit, the Northern Ontario Energy Credit, and the Ontario Sales Tax Credit
• Canada Workers Benefit — for working-age Canadians with lower income

These benefits are calculated based on your income in your first full year of Canadian residency and begin the benefit year following that — so the sooner you file, the sooner payments start.

Foreign Income Verification: T1135 May Not Apply in Year One

The T1135 foreign property disclosure form is required only for property you held as a Canadian tax resident. Property you owned before your arrival date gets a deemed acquisition — meaning the cost base resets to fair market value at arrival. Whether T1135 is required in year one depends on whether the cost of your specified foreign property (at its new fair market value on arrival) exceeds the reporting threshold. Consult a cross-border tax professional to assess this for your situation.

Tax Treaties and Foreign Tax Credits

If your home country taxes income you also report to Canada (for instance, you receive a pension from your former country throughout the year), Canada generally allows a foreign tax credit for taxes paid abroad on the same income, preventing double taxation. The foreign tax credit is calculated on Form T2209. The availability of treaty benefits depends on which country you came from — verify with a cross-border tax professional.
