1. How CRA Foreign Tax Credits (FTC) Are Calculated
When a Canadian tax resident earns income in a foreign country and pays foreign income tax, Canada grants a Foreign Tax Credit (FTC) under Section 126 of the Income Tax Act to eliminate double taxation.
Key Framework Highlights:
- Lesser of Rule: The FTC allowed by CRA is equal to the LESSER of the actual foreign tax paid OR the Canadian tax payable on that foreign income
- Form T2209 Federal FTC: Used to calculate the federal portion of foreign tax credits
- Form T2036 Provincial FTC: Used to calculate provincial foreign tax credits if federal FTC is capped
- Non-Business vs Business Foreign Income: Separate calculations for passive/employment income vs foreign branch business income
Action Checklist:
- Obtain official foreign tax payment receipts and foreign tax returns
- Convert foreign currency tax paid to CAD using Bank of Canada rate
- Calculate FTC limit on Form T2209 and claim on T1 Line 40500
