Corporate tax planning
What is a CCPC, and why does it matter for your tax bill?
Most Ontario owner-managed companies are Canadian-controlled private corporations without anyone deciding it. That status is worth $76,500 a year on $500,000 of profit, and it can be lost without anyone noticing.
A Canadian-controlled private corporation (CCPC) is a private corporation created in Canada and controlled by Canadian residents. Most owner-managed businesses and professional corporations in Ontario qualify. What matters is what the status unlocks, and the ways it quietly erodes.
The definition, in plain words
To claim the small business rate, all three of these must hold throughout the tax year:
- It is a Canadian corporation: incorporated in Canada, or resident here since before June 1971.
- It is private: no class of its shares is listed on a designated stock exchange.
- It is not controlled by non-residents or public corporations, alone or in any combination, directly or indirectly.
"Control" covers both kinds: voting control on paper, and practical control through debt, contracts or influence. A company with Canadian owners on paper can still fail if a non-resident relative or investor effectively runs it.
Why it matters: the 2026 Ontario rates
CCPC status unlocks the small business deduction. An Ontario CCPC pays 11.2% on its first $500,000 of active business income, compared with 26.5% for other corporations. On a full $500,000 that is $76,500 less corporate tax each year, kept in the company to invest, pay down debt or pay out later.
| Type of corporate income | Federal | Ontario | Combined |
|---|---|---|---|
| Active business income, first $500,000 CCPC, small business deduction | 9% | 2.2% from July 1, 2026 (3.2% before) | 11.2% (12.2% before) |
| Active business income above $500,000 or any corporation that is not a CCPC | 15% | 11.5% | 26.5% |
| Investment income earned by a CCPC interest, rent, taxable capital gains | 38.67% | 11.5% | 50.17%, with 30.67 points refunded when taxable dividends are paid |
Ontario's cut took effect mid-year, so a December 31 year-end blends to about 11.7% for 2026. See Ontario's 2026 small business rate cut for how your year-end affects it.
The $500,000 limit, and what shrinks it
The limit is not per company. Associated corporations, generally companies controlled by the same person or related people, share one $500,000 between them. Opening a second company does not get you a second limit.
Two grinds, both based on last year
Passive income grind
$50K → $150K
Each $1 of investment income above $50,000 cuts the federal limit by $5, so it is gone at $150,000. Ontario does not follow this grind, so a ground-down Ontario company pays about 17.2%, not 26.5%.
Taxable capital grind
$10M → $50M
The limit shrinks as the associated group's taxable capital employed in Canada rises from $10 million, and reaches zero at $50 million.
Investment income in an associated holding company counts too, so moving the portfolio to a holdco does not escape the grind. The usual answers are timing capital gains, investing for growth rather than interest, an individual pension plan, or paying out more income. See salary vs. dividends.
Professionals should watch one more rule. Income from services provided to another private corporation that you or a relative has an interest in can be "specified corporate income", which does not get the small business rate unless that corporation assigns part of its own limit. See tax planning for professional corporations.
Investment income, dividends and the capital gains exemption
CCPC status shapes how money leaves the company, not just how it is taxed inside it.
- Refundable tax on investment income. A CCPC pays about 50% on interest and rent up front, but 30.67 points of it come back when the company pays taxable dividends. The design makes investing through a corporation roughly as costly as investing personally.
- Two kinds of dividends. Income taxed at the small business rate comes out as non-eligible dividends. Income taxed at the general rate can be paid as eligible dividends, which carry a larger credit. Ontario's non-eligible dividend credit drops on January 1, 2027, so a 2026 versus 2027 payout matters.
- The lifetime capital gains exemption. Shares of a CCPC can shelter up to $1.25 million of gain on a sale (indexed from 2026) if they are qualified small business corporation shares: 90% or more of the assets used in an active business in Canada at the sale, more than 50% throughout the prior 24 months, and no one but you or a related person owning the shares in those 24 months.
The 90% test is another reason surplus cash matters. A company that has built up a portfolio may need to "purify" before a sale, and that takes planning time.
How companies lose CCPC status
Status can change mid-year, often without anyone noticing until the return is prepared. The most common causes:
An owner moves abroad
If non-residents end up controlling the company, alone or together, it stops being a CCPC. That includes a sole shareholder relocating for work.
A non-resident or public company invests
Bringing in a foreign partner or a listed company as a major shareholder can tip control.
Options and buy-sell rights
A right to acquire shares is treated as already exercised for this test. Signing a purchase agreement with a public company can end CCPC status before the deal closes.
A non-resident relative
Family members outside Canada who hold enough shares, or who effectively direct the business, count against you.
Losing status can also trigger a deemed year-end and an extra tax return. If a sale, a move or a new investor is coming, talk to your CPA before signing anything. The rules also run the other way: for tax years ending after April 7, 2022, "substantive CCPCs" that are Canadian-owned but structured to avoid the status are taxed like CCPCs on investment income.
Common questions
How do I know if my corporation is a CCPC?
Check line 040 on page 1 of your T2 return, which reports the type of corporation. If your company is Canadian-incorporated, private and controlled by Canadian residents, it is almost certainly a CCPC.
Is a professional corporation a CCPC?
Yes. An Ontario professional corporation owned by Canadian-resident professionals is a CCPC and can claim the small business deduction, subject to the specified corporate income rules.
What is the CCPC tax rate in Ontario for 2026?
11.2% on the first $500,000 of active business income from July 1, 2026 (12.2% before), and 26.5% above that.
Does a holding company get the small business deduction?
Only on active business income, and it shares the $500,000 limit with associated companies. Investment income in a holdco is taxed at about 50%, partly refundable.
Can a CCPC have a non-resident shareholder?
Yes, as long as non-residents and public companies do not control it, alone or together.
Is your corporation getting the CCPC benefits it should?
Book a free consultation. I will review the structure, the passive income picture and the dividend mix together, so the small business rate is protected now and the capital gains exemption is still there when you sell.
