The $50,000 Passive Income Rule: What Ontario Business Owners Should Know

What is the small business deduction?

The small business deduction gives some companies a lower tax rate. It is for a Canadian-controlled private corporation. That is a private company. Generally, it is not controlled by people outside Canada or by public companies.

Such a company pays a lower rate on its first $500,000 of active business income each year. Active business income is the money it earns from running its business.

In Ontario, the small business rate is 11.2% as of July 1, 2026. That is the federal and Ontario rates added together. Before that date, it was 12.2%. Income above the $500,000 limit is taxed at 26.5%.

That is a big gap. It is why most owner-run companies care about keeping the full $500,000.

How does passive income shrink it?

Passive income is money the corporation earns from its investments, not from running its business. For every $1 of passive income above $50,000, the federal limit goes down by $5.

The tax rules have a name for the passive income used in this test. It is called adjusted aggregate investment income. Think of it as the company's passive income, counted under the tax rules.

It is based on the previous tax year. It also adds together all associated corporations. These are companies the tax rules link together. One example is a holding company and the operating company it controls. So a holding company's investments count against its operating company.

• At $50,000 of passive income or less, the limit does not go down.
• At $100,000, the federal business limit falls by $250,000.
• At $150,000 or more, the federal business limit is gone.

Ontario has not adopted this cut for its own small business rate. So for an Ontario corporation, the extra cost shows up on the federal side. Income that loses the small business deduction is taxed federally at 15% instead of 9%.

Part of that extra tax can come back later. Income taxed at the higher general rate lets the corporation pay eligible dividends. Eligible dividends are taxed more lightly when you get them personally.

The true cost depends on how and when money leaves the corporation. That is a question for your accountant.

What counts as passive income?

Broadly, it is investment income that does not come from the active business. It includes:

• Interest and most rental income
• Dividends from portfolio investments
• The taxable half of capital gains on investments, once they are realized. A capital gain is the profit when an investment is sold for more than it cost. Realized generally means sold.
• Foreign investment income, which is investment income from outside Canada

Some things do not count:

• Capital gains on assets used in the active business
• Dividends from connected corporations. Generally, these are companies your corporation controls, or owns enough of under the tax rules.
• Growth inside an exempt life insurance policy. An exempt policy is one that meets certain tax rules.

How do owners manage it?

None of these steps is right for everyone. Each one has its own trade-offs. They are worth raising with your accountant once passive income gets close to $50,000.

Here are three plans to ask about:

• A Corporate Insured Retirement Program. This uses corporate-owned life insurance. The corporation owns a whole life insurance policy on the owner. It is insurance first. When the owner dies, the death benefit goes to the corporation tax-free. Growth inside an exempt policy is not taxed each year. It does not count as passive income either. See our Corporate Insured Retirement Program page.
• An Individual Pension Plan (IPP). This is a pension plan the corporation sets up for the owner. The money the corporation puts in is generally tax-deductible. That means it can be subtracted from the corporation's income for tax. It also moves money out of the corporation's investment account and into a pension. Growth inside the plan is sheltered from tax. The pension is taxed when it is paid out. See our IPP guide.
• Shared ownership critical illness insurance. Critical illness insurance pays if the owner gets a serious illness the policy covers. The corporation owns and pays for this benefit. If there is a claim, the corporation gets the benefit tax-free. The owner owns and pays for a return of premium rider, which is an add-on. If there is no claim, the owner can generally get all the premiums back tax-free. Learn more on our critical illness insurance page.

Your accountant may also look at these steps:

• Investment mix. Growth that is not realized yet is not counted. When a capital gain is realized, only half of it counts. Some investments are built to grow over time. Each year, they tend to make less passive income than ones that pay a lot of interest.
• Paying more out. Paying yourself more salary or dividends leaves fewer investments in the corporation. The trade-off is personal tax today.
• Timing. The test uses last year's income. So the year a gain is realized can matter.

Where do I start?

Ask your accountant two questions. What was your corporation's passive income last year? What is it likely to be this year?

Is the answer close to $50,000, or above it? Then it is a good time for a joint talk about which options fit. We can work out the numbers for the insurance and pension side. Then we can share them with your accountant to review.
