Introduction
Canada's individual income tax return — the T1 General — covers the calendar year and is filed with the Canada Revenue Agency (CRA). Canada uses a federal-plus-provincial tax system: federal rates apply to all Canadians, but each province adds its own income tax on top, making the total effective rate vary significantly by province. For expats in Canada or Canadians living abroad, residency determination is the pivotal question — Canadian residents are taxed on worldwide income; non-residents pay only on Canadian-source income.
This guide covers Canadian tax residency rules, T1 filing deadlines and the online system, provincial tax differences, treatment of foreign income, RRSP rules relevant to expats, and the special complexity facing US citizens in Canada.
Section 01
Canadian Tax Residency Rules
Canada uses a facts-and-circumstances approach to tax residency, not a strict day-count test (though days are a factor).
Factual Residents
You are a Canadian tax resident if you have significant residential ties to Canada: a home available for use in Canada; a spouse/common-law partner or dependents remaining in Canada; personal property and social ties (driver's licence, bank accounts, health card, provincial memberships). Canadians who leave Canada but maintain these ties are frequently determined to remain resident — the CRA can reassess years after departure.
Deemed Residents
You are a deemed Canadian resident if you are sojourning (temporarily present) in Canada for 183+ days in a calendar year and are not resident under the factual test.
Non-Residents
Non-residents are taxed only on Canadian-source income: employment income for work physically performed in Canada, Canadian rental income, gains on Canadian real property (taxable under section 116 — notified to CRA within 10 days of sale), and most Canadian dividends and interest (withholding tax applies).
Deemed Residents on Departure
When a Canadian tax resident leaves Canada and establishes non-residency, a 'deemed disposition' occurs: all capital property is treated as sold at fair market value on departure day. This triggers capital gains on unrealised gains at that date. RRSP/RRIF accounts, employer pension plans, and certain other assets are excluded from deemed disposition.
Section 02
Filing the T1 Return and Key Deductions
CRA My Account and NETFILE
The CRA's My Account portal and NETFILE system allow online filing. Most major Canadian tax software (TurboTax Canada, Wealthsimple Tax, H&R Block Canada) connect directly to NETFILE. CRA Auto-fill my return pre-populates T4 slips, investment income slips, and benefit statements from employer and financial institution filings.
RRSP (Registered Retirement Savings Plan)
RRSP contributions reduce taxable income (deductible up to 18% of prior year earned income, max $31,560 in 2024). For expats moving to Canada: if you have prior-year earned income in Canada, you have accumulated RRSP room from those years. For expats leaving Canada: RRSP withdrawals by non-residents are subject to 25% non-resident withholding (15% under some treaties). RRSP to RRIF conversion must occur by December 31 of the year you turn 71.
Key Deductions for Expats
Moving expenses: Deductible if you moved to Canada for employment or business income — costs include transport, travel, storage, and temporary accommodation
Foreign tax credits: Claimed on Form T2209 — offsets Canadian federal tax for foreign taxes paid on the same income
Provincial foreign tax credits: Separate credits available in most provinces (Form T2036)
Child care expenses: Two-thirds of childcare costs up to $8,000/year per child under 7
Employment expenses: Work-from-home flat rate ($2/day up to 400 days) or actual office costs with T2200 signed by employer
Section 03
US-Canada Cross-Border Tax Issues
The US-Canada cross-border tax relationship is among the most complex in the world, given the large population of dual citizens and cross-border workers.
US Citizens in Canada
US citizens resident in Canada must file both a Canadian T1 return and a US 1040 return (worldwide income). The US-Canada tax treaty provides Foreign Tax Credit relief: Canadian federal and provincial taxes paid are credited against US tax liability on the same income. Because Canadian taxes are generally higher than US taxes, many US citizens in Canada have zero net US tax liability (though the filing obligation and FBAR/FATCA reporting requirements remain).
RRSP and US Tax Treatment
The US-Canada tax treaty (Article XVIII) allows US citizens in Canada to defer US taxation of RRSP income until withdrawal — matching Canadian treatment. Without this treaty provision, the IRS would tax RRSP growth annually as a foreign grantor trust. The treaty election must be made on the US return (Form 8891 was previously required; current IRS guidance allows treaty claims on the return itself). This is one of the most important US-Canada treaty provisions for expats.
Canadian Departure Return
In your final year as a Canadian tax resident, you file a departure return: reporting income up to your departure date; triggering deemed disposition; claiming treaty residency if applicable. The CRA may require payment of the resulting capital gains tax immediately — a potential liquidity issue if you have large unrealised portfolio gains.
US citizens in Canada face two full tax returns each year. Greenback's CPAs specialise in US-Canada cross-border returns — RRSP treaty elections, Foreign Tax Credit, FBAR, and T1/1040 coordination done correctly.
⚠ Not the cheapest option — best for complex situations and expats who want a dedicated CPA.
Sending Canadian dollars to the CRA from a foreign bank account? Wise transfers CAD at the real exchange rate with low fees — significantly cheaper than bank wire transfers for cross-border tax payments.
⚠ For currency exchange only — not a bank account replacement.
Do I need to file a Canadian tax return if I lived in Canada for only part of the year?
Yes — if you were a Canadian tax resident for any part of the year, you must file a T1 return for that year. Your income is reported from the date you established Canadian residency (arrived and established residential ties) to December 31 or your departure date if you left mid-year. The basic personal amount and other credits are prorated based on the number of days you were resident. If you arrived in Canada during the year from a treaty country, the income you earned in the other country before arriving may still need to be declared on the Canadian return (particularly for the alternative minimum tax calculation), even if it's ultimately exempt from Canadian tax under the treaty.
Q
How are Canadian RRSPs taxed when withdrawn by a non-resident?
When a non-resident of Canada withdraws from an RRSP: a 25% non-resident withholding tax applies to the full withdrawal amount. However, most of Canada's tax treaties reduce this rate: USA 15% (under the Canada-US treaty for periodic payments; 25% for lump-sum payments above certain thresholds); UK 25%; Australia 25%. The withholding is a final tax — non-residents do not need to file a Canadian return solely because of RRSP withdrawals. Important: if you converted your RRSP to a RRIF before departing Canada (mandatory by age 71 regardless), minimum annual RRIF withdrawals continue to be subject to the same withholding rates. US citizens receiving RRSP/RRIF payments must also declare them on their US return — under the US-Canada treaty, they are taxable in the US in the same manner as equivalent US pension income.
Q
What is the Canadian deemed disposition rule on departure?
When you stop being a Canadian tax resident, you are deemed to have disposed of most capital property at its fair market value on the departure date — triggering capital gains on any unrealised appreciation. Capital gains are then included in income for the departure year at the inclusion rate (50% for gains up to $250,000, 66.67% above that under the 2024 increase, which may be subject to legal challenge). Assets excluded from deemed disposition: Canadian real property, Canadian business assets, and registered accounts (RRSP, TFSA, RESP, RRIF). You can elect to post 'security' with the CRA instead of paying the capital gains immediately — useful if you can't liquidate assets to pay the tax. The deemed disposition is reported on Schedule 3 (Capital Gains) of your departure year T1.
Q
Is income earned before moving to Canada taxed in Canada?
Generally no — income earned before you became a Canadian tax resident is not taxable in Canada, even if received after your arrival. Your Canadian income starts from the date you establish Canadian residency. However: employment income attributable to services performed in Canada is always taxable in Canada, regardless of residency timing (this affects people who do work in Canada before formally establishing residency); capital gains on Canadian property (real estate, shares of Canadian private companies) can be taxable in Canada even for non-residents; and the alternative minimum tax on the first return may consider global income in the calculation. Always keep clear records of the date income was earned vs received to correctly apportion income to pre- and post-arrival periods.
Q
What are Quebec's special tax filing requirements?
Quebec is unique in Canada: residents of Quebec file two separate income tax returns — one federal T1 return and one provincial TP-1 return for the Quebec provincial tax authority Revenu Québec. Both returns cover the same income but apply different tax rules. Key Quebec differences: Quebec calculates its own provincial basic amounts, credits, and deductions; Quebec residents receive a larger federal tax abatement (16.5% reduction in federal tax to account for Quebec administering its own social programs); Quebec has its own pension plan (QPP vs CPP federally); Quebec's Health Services Fund levy applies to individuals without employer health coverage. For expats: if you move to Quebec, you need to understand both filing systems, as Revenu Québec audits separately from the CRA.
