No Nigeria-Canada Tax Treaty: Implications
Canada and Nigeria do not have a bilateral income tax convention. This means: no reduced withholding on Canadian dividends paid to Nigerian residents; no formal treaty tiebreaker for dual residents; no treaty-based pension exemptions; no exchange of information article (though Canada participates in the CRS — Common Reporting Standard — under OECD, which covers information exchange). For Canadian residents earning Nigerian income: rely on Canada's domestic foreign tax credit (FTC) under Section 126 of the Income Tax Act to offset Canadian tax on Nigerian-source income that has been taxed in Nigeria. Nigerian WHT (withholding tax) on Nigerian dividends (10%), interest (10%), and rent (10%) generates credits. Without a treaty, all other income types taxed in Nigeria simply use the domestic Section 126 credit. The absence of a treaty does not create unavoidable double taxation — the domestic FTC system generally prevents it — but it does mean there are fewer planning opportunities and more complexity.
Canadian Worldwide Taxation: When It Begins
Canadian income tax applies to residents on their worldwide income. You become a Canadian tax resident on the date you establish residential ties in Canada — typically the date you arrive with the intention to reside, or the date you receive your Permanent Resident (PR) card status. Residential ties: the CRA (Canada Revenue Agency) considers your dwelling place in Canada, spouse/dependants in Canada, personal property (furniture, car), social ties (club memberships, provincial health insurance, driver's license). The 'sojourner rule': if you are physically present in Canada for 183+ days in a calendar year and are not considered resident by ties, you are still deemed resident for the full year. For Nigerian immigrants arriving mid-year: you are resident from arrival date; income earned before Canadian arrival (Nigerian income) is generally not subject to Canadian tax for the year of arrival. T1 return: file for the year of arrival showing Canadian-period income; income from before arrival reported only if it was Canadian-source (very unlikely).
First-Year Canadian Tax Return: T1 for Immigrants
The T1 General income tax return is Canada's personal income tax form. For new immigrants: the first-year return covers from arrival date to December 31. Partial-year prorated tax: federal and provincial personal tax credits are prorated for the partial year of residency. Federal personal amount: CAD $16,452 (2026); prorated by days as Canadian resident / 365. Provincial amounts vary by province. Canadian income tax rates (federal, 2026): 14% on first CAD $58,523; 20.5% on $58,524–$117,045; 26% on $117,046–$181,440; 29% on $181,441–$258,482; 33% above $258,482. Plus provincial rates (Ontario adds 5.05–13.16%; BC adds 5.6–20.5%; Alberta adds 8–15%; etc.). NETFILE: file online via CRA's NETFILE portal; new immigrants may need to file paper return in first year if they don't have a prior-year Canadian return. SIN (Social Insurance Number): obtain immediately upon arriving — required to work and file taxes in Canada.
RRSP and TFSA: Tax-Advantaged Accounts for New Canadians
New Canadian residents can immediately use key tax-advantaged accounts: TFSA (Tax-Free Savings Account): contribution room accumulates from age 18, but for immigrants, room only accumulates from the year you become a Canadian resident (not from 18 if born before Canadian residency). 2025 TFSA limit: CAD $7,000 (cumulative limits apply — if you arrived in 2023, you have 2023+2024+2025 room ≈ $21,500 cumulative). Investments inside TFSA grow completely tax-free — dividends, capital gains, interest all sheltered. RRSP (Registered Retirement Savings Plan): contribution room is based on 18% of prior year's earned income (max $31,560 for 2025). New immigrants have no contribution room in their first year (no prior Canadian income). Room accumulates starting from year two. RRSP contributions reduce taxable income dollar-for-dollar (tax deductible). Strategy: in high-income early years of Canadian residency, RRSP contributions are very valuable. Nigerian pension or retirement plan assets cannot be rolled into a Canadian RRSP without triggering income — the funds remain in Nigeria as non-registered savings from a Canadian tax perspective.
T1135: Reporting Nigerian Foreign Assets
Canadian residents must file Form T1135 (Foreign Income Verification Statement) if the total cost amount of specified foreign property exceeds CAD $100,000 at any time during the year. Specified foreign property includes: Nigerian bank accounts, shares in Nigerian companies (not held through a Nigerian registered retirement plan), Nigerian real estate not used principally as your principal residence, interests in foreign trusts, foreign investment accounts. Property used personally (your personal residence in Nigeria, if you still maintain one) may be excluded. T1135 is informational — it does not create additional tax, but failure to file results in significant penalties ($25/day up to $2,500 for late filing; up to $500/month for failure to file). Many Nigerian-Canadians significantly underestimate the value of their Nigerian assets when calculating whether they exceed CAD $100,000 — Nigerian bank deposits, property equity, and business stakes all count. File T1135 with your T1 return by April 30 (or June 15 if self-employed).
