How It Works and How It Can Reduce Your Taxes

Investing in small businesses can offer significant opportunities — but it also comes with risk. If your investment in a Canadian private company fails, you may be able to claim a powerful tax deduction known as an Allowable Business Investment Loss (ABIL).

At Toro Accounting, we help investors and entrepreneurs properly structure and claim these losses to maximize their tax benefit.

Here’s what you need to know.

🔹 What Is an ABIL?

An ABIL is a special type of capital loss that arises when:

✔ You dispose of shares of a small Canadian private corporation at a loss, or
✔ A loan you made to a small business becomes uncollectible

The rules are administered by the Canada Revenue Agency (CRA).

Unlike regular capital losses, an ABIL can be deducted against any type of income, not just capital gains — making it significantly more valuable.

🔹 What Type of Company Qualifies?

To qualify as an ABIL, the investment must relate to a:

✔ Canadian-Controlled Private Corporation (CCPC)
✔ Company that used most of its assets in an active business carried on in Canada
✔ Small business corporation (not publicly traded)

Not all investments qualify.

🔹 How Is It Calculated?

Normally:

• Only 50% of capital losses are deductible (allowable capital loss)
• And they can only offset capital gains

With an ABIL:

• 50% of the total business investment loss becomes the Allowable Business Investment Loss
• That amount can be deducted against:
  • Employment income
  • Business income
  • Rental income
  • Interest income
  • Other taxable income

Example:

You invested: $100,000
Recovered: $0
Total loss: $100,000

50% ($50,000) becomes an ABIL that can reduce any taxable income.

🔹 What If You Can’t Use It All?

If you cannot fully use the ABIL in the current year:

✔ It can be carried back 3 years
✔ It can be carried forward 10 years

After 10 years, any unused amount converts into a regular capital loss (which can then only offset capital gains).

🔹 Situations That May Qualify

✔ Shares of a startup that shut down
✔ Personal loan to a corporation that became insolvent
✔ Investment in a small private company that dissolved with no remaining value

There must be clear evidence that the investment is completely worthless or uncollectible.

🔹 Situations That Do NOT Qualify

❌ Investments in publicly traded companies
❌ Foreign corporations
❌ Unrealized losses (the company still operates)
❌ Temporary declines in value

The loss must be realized and documented.

🔹 Strategic Tax Planning

An ABIL can:

✔ Significantly reduce taxable income
✔ Generate meaningful tax refunds
✔ Improve long-term tax planning flexibility

However, documentation and proper reporting are critical. The CRA closely reviews these claims.

🔹 Common Mistakes

❌ Failing to confirm CCPC status
❌ Not proving a loan is truly uncollectible
❌ Not formally realizing the loss
❌ Reporting it incorrectly as a regular capital loss

Improper reporting may lead to reassessment.
