How Currency Exchange Rates Affect Your Canadian Tax Return

If you’re earning money abroad as a Canadian, you can’t just plug in the amount in foreign currency and call it a day.

The Canada Revenue Agency (CRA) requires all income, expenses, and certain assets to be reported in Canadian dollars, and that means using the correct currency exchange rates.

At Accounting Montreal, we help expats get these conversions right to avoid penalties, overpayment, or triggering an audit.

Why Exchange Rates Matter in Taxes

The CRA calculates taxes based on Canadian dollar values, so:

• Reporting too little income by using the wrong rate can lead to interest and penalties.
• Reporting too much can mean paying unnecessary extra taxes.

Which Exchange Rate Should You Use?

1. Annual Average Rate

• Used for most types of foreign income (salary, business income, pensions).
• Published yearly by the Bank of Canada.

2. Daily Rate

• Used for one-off transactions like asset sales or lump-sum payments.
• Use the Bank of Canada rate for the specific transaction date.

3. Year-End Rate

• Used for valuing foreign investments or accounts on December 31 for reporting purposes (such as T1135).

Reference: Bank of Canada Exchange Rates

Example: Salary Conversion

Mark works in Germany and earns €50,000 in 2024. The Bank of Canada’s 2024 annual average rate is 1.47.

• €50,000 × 1.47 = $73,500 CAD taxable income reported to the CRA.

Exchange Rates and Investment Income

If you receive foreign dividends, interest, or capital gains, each transaction should be converted using:

• Daily rates for capital gains
• Average annual rate for recurring income like dividends or interest (if consistent)

Common Mistakes Expats Make with Exchange Rates

1. Using credit card rates instead of official Bank of Canada rates
2. Mixing rates for the same income type
3. Forgetting to convert both income and related expenses
4. Using the wrong year’s rate for prior-year income
