U.S. Brokerage Account: I Never Withdrew the Money… So Why Would I Owe Tax?

Understanding realized and unrealized gains on foreign investment accounts

By Roberto Belingueres, Founder & CEO, RGB Accounting  |  7-minute read

As more Canadians invest internationally through foreign brokerage and wealth-management firms, one question keeps coming up: “I did not withdraw any money, so why would I owe tax?” The answer depends on whether the investments merely increased in value or whether you actually sold securities inside the account.

The Difference Between Market Growth and Taxable Gains

Scenario 1: Unrealized gain

Suppose you purchase investments for USD $100,000 and they are worth USD $140,000 at year-end. If nothing has been sold, the USD $40,000 increase is generally an unrealized gain. In most cases, this market appreciation is not taxable in Canada at that time because no disposition has occurred.

Scenario 2: Realized gain

Now suppose the portfolio manager sells those securities and immediately reinvests the proceeds. You may never receive cash in your personal bank account, but a sale has still occurred. For Canadian tax purposes, that sale will generally be a disposition that can create a capital gain or capital loss.

Key point: Canadian tax generally focuses on whether an investment was sold—not whether the proceeds were withdrawn from the account.

What Happens in Managed Investment Accounts?

Many investors use discretionary portfolio-management services. In these arrangements, an advisor may buy and sell securities without obtaining the investor’s approval for every individual trade. The proceeds can remain entirely inside the account and be reinvested automatically.

Annual statements may therefore contain all of the following:

• Market appreciation or depreciation
• Unrealized gains and losses
• Realized gains and losses
• Dividends
• Interest income
• Foreign taxes withheld
• Advisory fees and transaction costs

Only the appropriate taxable amounts should be reported on the Canadian return. The portfolio’s total increase in value is not automatically the capital gain to report.

Why Reinvestment Does Not Erase a Disposition

A frequent misconception is that no tax arises because the proceeds were reinvested. Reinvestment is a separate transaction. Once you sell securities, you generally realize the gain or loss. Buying replacement securities does not reverse that sale or defer the Canadian tax consequences unless a specific rollover provision applies.

For example:

1. Shares are purchased for $25,000.
2. The shares are later sold for $40,000.
3. The $40,000 is immediately used to purchase a different investment.
4. The investor withdraws nothing.

The first sale may still produce a $15,000 capital gain before transaction costs and Canadian-dollar conversion adjustments.

Documents Needed for Accurate Reporting

Foreign brokerage statements can be complex. A year-end portfolio summary alone may not be sufficient. Depending on the institution and country, the supporting package may include:

• Annual Tax Package or Consolidated Tax Reporting Statement
• Form 1099-B or equivalent disposition report
• Form 1099-DIV
• Form 1099-INT
• Cost Basis Report or tax-lot report
• Complete year-end account statements
• Foreign tax withholding details
• Trade confirmations when the tax package is incomplete

These records help distinguish realized gains from unrealized appreciation, identify dividends and interest, determine foreign tax credits, and support the adjusted cost base used for Canadian reporting.

T1135 Versus the Canadian Income Tax Return

Form T1135 is an information return used to disclose certain specified foreign property when the applicable cost threshold is exceeded. It does not replace the requirement to report taxable income on the Canadian income tax return.

Depending on the facts, the taxpayer may still need to report:

• Capital gains and losses on Schedule 3
• Foreign interest and dividend income
• Foreign tax credits
• Business or trust income
• Other foreign-reporting forms

A T1135 can therefore be technically complete while the T1 remains incomplete—or the reverse. Both filings must be reconciled to the same underlying investment records.

Special Considerations for New Canadian Residents

The analysis becomes more complex when an individual becomes a Canadian resident during the year. In many cases, foreign capital property is treated as having a Canadian tax cost equal to its fair market value when Canadian residency begins. This “step-up” can materially affect future capital-gain calculations.

You must carefully document the exact immigration date, the fair market value on that date, subsequent purchases and sales, and foreign exchange conversions. Using the original foreign purchase price without considering the residency date can significantly overstate or understate the Canadian gain.

Frequently Asked Questions

Do I pay tax if I do not withdraw money from my investment account?

Possibly. If you sold securities, a disposition may have occurred even if all proceeds remained in the account and were reinvested.

Are unrealized gains taxable in Canada?

Generally, a simple increase in market value is not taxable until the property is disposed of. Exceptions can apply in specialized circumstances.

Does my foreign advisor’s automatic trading create taxable gains?

Yes, potentially. A discretionary advisor’s sale of securities can create realized gains or losses for the account owner.

Does filing T1135 report all of my foreign investment income?

No. T1135 is an information return. Capital gains, dividends, interest and foreign tax credits are reported elsewhere on the Canadian return.

What documents should I obtain from a U.S. broker?

The annual tax package, Form 1099-B, 1099-DIV, 1099-INT, cost-basis reports and year-end statements are common starting points.

What if the gains were omitted from prior Canadian returns?

Complete a year-by-year review before filing adjustments. The appropriate correction method depends on the years involved, the amounts, existing T1135 filings and whether CRA has already contacted the taxpayer.

Final Takeaway

The most important distinction is not whether cash left the account. It is whether investments were sold. A managed foreign account can generate realized capital gains, dividends and interest even when the investor receives no cash personally and the entire portfolio remains invested.

Reviewing the supporting documentation before filing can prevent omissions, reduce the risk of reassessment, and create a clear audit trail for the CRA.
