One of the most significant tax consequences of leaving Canada is the potential application of departure tax.

While many people understand that moving can affect their tax residency, fewer understand how departure tax is actually calculated.

What Is Departure Tax?

Departure tax is the tax that may arise when the CRA applies deemed disposition rules to certain assets as you become a non-resident of Canada.

The tax is not based on an actual sale.

Instead, it is based on unrealized gains that have accumulated while you were a Canadian resident.

How Is the Gain Calculated?

The process is relatively straightforward.

The CRA determines:

Fair Market Value on Departure Date

Minus

Adjusted Cost Base (Original Cost)

Equals

Capital Gain

The resulting gain is then included in your departure-year tax calculations according to Canadian tax rules.

Example

Suppose you purchased an investment portfolio for $100,000.

On the day you leave Canada, the portfolio is worth $250,000.

Even if you continue holding the investment after moving to the United States, the CRA may treat the portfolio as though it was sold for $250,000.

In this example:

• Fair Market Value: $250,000
• Cost Base: $100,000
• Unrealized Gain: $150,000

That gain may trigger departure tax.

What Happens If the Asset Has Lost Value?

The departure tax rules can feel one-sided to many taxpayers.

When assets have appreciated, the CRA may seek to tax the gain.

When assets have declined in value, the planning opportunities and treatment can become more limited and dependent on the specific circumstances.

This is one reason why professional analysis is important before relocating.

Why Timing Matters

The valuation date is critical.

The fair market value used for departure tax purposes is generally based on the date you become a non-resident.

A change in timing can significantly affect the value of certain investments and, therefore, the resulting tax liability.

Planning Before Departure

The best time to address departure tax is before becoming a non-resident.

By reviewing assets early, Canadians may be able to evaluate various planning strategies, understand potential tax costs, and make informed decisions before the departure date arrives.

Once residency status changes, many planning opportunities become more difficult or unavailable.
