Deductible Interest Tracker

Example: Handling Return of Capital Distributions

This walkthrough explains what happens when your ETF or fund distributes return of capital (RoC). RoC is common with Canadian ETFs and has specific implications for interest deductibility tracking.

What Is Return of Capital?

Return of capital is not income—it's your own invested money coming back to you. Unlike dividends or interest, RoC:

  • Is not taxable when received
  • Reduces your cost base (affecting future capital gains)
  • Returns borrowed capital as borrowed cash if the position was borrowed-funded

The Scenario

You hold 500 units of a monthly-distribution ETF. The position details:

AttributeValue
SymbolXYZ
Units500
Total Cost Base$12,500
Borrowed Cost Base$10,000 (80%)
Personal Cost Base$2,500 (20%)

The ETF pays a monthly distribution of $0.10 per unit, with a typical breakdown of 60% income and 40% return of capital.

Recording the Distribution

On March 15, you receive the distribution:

  • Total: $50.00 (500 × $0.10)
  • RoC portion: $20.00 (40%)
  • Income portion: $30.00 (60%)

Event: Investment Distribution

  • Date: March 15
  • Symbol: XYZ
  • Total amount: $50.00
  • Return of capital: $20.00

Calculations:

  1. Total RoC: $20.00
  2. Borrowed portion of RoC: $20.00 × 80% = $16.00
  3. Personal portion of RoC: $20.00 × 20% = $4.00
  4. Income portion: $30.00 (all goes to personal cash)

Personal Cost$2,500-$4.00$2,496

Understanding the Flow

The income portion ($30) goes entirely to personal cash. It's income—new money that's yours regardless of how the position was funded.

The RoC portion ($20) is return of your invested capital. Since 80% of your position was borrowed-funded:

  • $16 of borrowed capital returns as borrowed cash (uninvested principal)
  • $4 of personal capital returns as personal cash
  • Your cost base decreases by the full $20 RoC

The borrowed cost decrease is proportional to your position's borrowed percentage, not to the RoC percentage. If your position is 80% borrowed, 80% of any RoC reduces borrowed cost.

Over Time: The Compounding Effect

Let's see what happens over a year of monthly distributions with similar RoC:

Starting Position:

  • Total Cost: $12,500
  • Borrowed: $10,000 (80%)
  • Personal: $2,500 (20%)

After 12 months of $20 RoC distributions:

  • Total RoC received: $240
  • Borrowed cost reduced by: $192 (80% × $240)
  • Personal cost reduced by: $48 (20% × $240)

Ending Position:

  • Total Cost: $12,260 ($12,500 - $240)
  • Borrowed: $9,808 (80.0%)
  • Personal: $2,452 (20.0%)

The borrowed percentage stays the same because RoC is distributed proportionally. However, your invested principal has decreased by $192.

Where did the borrowed capital go? Each month, $16 went to borrowed cash in your brokerage. After 12 months, you've accumulated $192 in borrowed cash (assuming you didn't spend or reinvest it).

What to Do with Accumulated Borrowed Cash

You have three choices:

1. Reinvest it Buy more securities with the borrowed cash to move it back to invested status.

  • Maintains invested principal
  • Keeps interest deductibility maximized

2. Leave it as cash The borrowed cash sits in your brokerage.

  • Interest on uninvested principal may still be deductible if you're actively investing
  • More conservative tracking treats it as non-deductible

3. Withdraw it Take the cash for personal use.

  • Converts uninvested principal to personal-use principal
  • Interest on that portion becomes clearly non-deductible

For most leveraged investors, reinvesting accumulated RoC makes the most sense—it maintains the invested principal that generates deductible interest.

RoC Information Sources

You'll find RoC breakdowns in several places:

T3 Tax Slips (February-March for previous year) Box 42 shows return of capital. This is the definitive number for tax purposes.

Fund Company Websites Many ETF providers publish monthly distribution breakdowns. Check the "distributions" or "tax center" section.

Estimated vs. Final Fund companies often provide estimates during the year, with final figures in tax slips. You can record distributions with estimated RoC and adjust when final numbers arrive.

A Common Mistake

Wrong approach: Recording the full distribution as income (zero RoC).

This overstates personal cash and fails to reduce your cost base. When you eventually sell, your capital gain will be understated, and your borrowed/personal tracking will be off.

Correct approach: Always check for RoC and record it accurately.

Even if you don't have the final T3 numbers, use the fund's estimated breakdown. Adjust later if needed.

When RoC Exceeds Cost Base

In extreme cases (long-held positions with heavy RoC), cumulative RoC can exceed your original cost base. When this happens:

  • Cost base goes to zero
  • Excess RoC is treated as a capital gain in the year received
  • The app will alert you if this situation occurs

This is rare but possible with certain types of funds held for many years.

Key Takeaways

  1. RoC reduces your cost base and borrowed allocation. It's return of capital, not income.
  1. The borrowed portion of RoC becomes borrowed cash. This slightly reduces your invested principal each time.
  1. Track RoC accurately. Use estimates during the year and adjust when final tax slips arrive.
  1. Consider reinvesting accumulated borrowed cash. This maintains your invested principal and deductible interest.
  1. RoC doesn't change your borrowed percentage. Both borrowed and personal cost decrease proportionally.
