Holdco — Holding Company (Holdco)
Last updated April 24, 2026 · By Evermore Private Wealth · Corporate Structure
Holdco — Holding Company (Holdco). A holding company (Holdco) is a Canadian private corporation that owns shares of one or more operating companies (Opcos), or that holds passive investments. Holdcos are commonly used by Canadian business owners to defer personal tax on after-tax operating profits, creditor-proof retained earnings, fund insurance and investments inside the corporate structure, and enable estate-planning strategies like the estate freeze.

Why business owners use Holdcos
The most common use is the tax deferral created by leaving after-tax operating profits in the corporate structure rather than paying them out as dividends to the owner. Operating profits are taxed at the corporate rate (12.2% on the first $500k of active business income in Ontario; 26.5% above). When dividended out personally, additional 'gross-up' tax brings the effective combined rate close to the personal marginal rate. Until that dividend happens, the difference is deferred capital that can be invested.
Holdco-Opco structure
The classic structure: Founder owns Holdco; Holdco owns Opco. Opco pays inter-corporate dividends up to Holdco tax-free under section 112. Holdco invests the proceeds, owns life insurance on the founder, makes loans back to Opco, and in many structures also holds the founder's preferred shares from an estate freeze. This isolation creditor-proofs the operating business profits — if Opco is later sued, Holdco assets are typically out of reach.
What this means for HNW Canadian families
The 2018 federal passive income rules permanently changed the Holdco math. If your Holdco (and associated companies) earns more than $50,000 of passive investment income in a year, the small-business deduction at the Opco level starts to grind down — and is fully eliminated at $150,000 of passive income. For founders with mature Holdcos, this creates a real tension between corporate-class growth and the small-business deduction. We model the breakeven for every business-owner client, and frequently the right answer is to systematically distribute dividends out of Holdco into the founder's RRSP and TFSA each year — paradoxically, the personal accounts often become the better long-term shelter.
Worked example — Tax deferral with a Holdco
An Ontario business earns $400,000 of active business income. Inside the small-business deduction, that's taxed at 12.2%, leaving $351,200 of after-tax profit available to invest inside the company. If the founder had instead taken the full $400k as salary, after-tax personal cash would be approximately $217,000 (at a 53.53% effective marginal rate). That's a $134,000 deferral available to invest each year inside the corporate structure — the founder owes the personal tax eventually when the funds are dividended out, but every year of tax-free compounding on the deferred amount adds to the family balance sheet.
Common Questions
What is the difference between Holdco and Opco?
Opco (operating company) is the active business that earns revenue, employs staff, and signs customer contracts. Holdco (holding company) is a passive corporation that owns shares of Opco and holds the after-tax retained profits as investments. The structure separates business risk from accumulated wealth.
Do I need a Holdco?
Most incorporated professionals don't need one until their business consistently generates more after-tax profit than they need for lifestyle. The classic trigger is when retained earnings inside Opco exceed roughly $250k–$500k. Below that, a Holdco adds annual accounting cost (typically $3k–$8k/year) without proportional benefit.
How is investment income taxed inside a Holdco?
Passive investment income inside a Canadian-controlled private corporation is taxed at a high refundable rate (50.17% in Ontario for 2025). The 'refundable' portion comes back when the corporation pays out a dividend, but the high upfront rate is what makes corporate investing less efficient than is widely believed — and what triggered the 2018 passive income rules that grind down the small-business deduction at the Opco level.
Can a Holdco own life insurance?
Yes — and this is one of its most powerful uses. Life insurance owned and paid for by Holdco results in tax-free death benefit proceeds being credited to the company's Capital Dividend Account (CDA), which can then be paid out tax-free to the estate. For HNW business owners, corporately-owned permanent insurance is a core estate-equalization and tax-funding tool.
