Introduction

Once an incorporated professional or business owner has accumulated retained earnings inside their corporation, a common next question emerges: should I set up a holding company?

The holding company — or "holdco" — is a legitimate and widely used corporate structure in Canada. But like most things in tax planning, it is not a universal solution. Understanding what a holding company does, and what it does not do, is the starting point for any informed conversation.

What Is a Holding Company?

A holding company is a corporation whose primary purpose is to hold assets — typically the shares of another corporation (the operating company, or "opco"), investments, real estate, or other property — rather than to conduct active business operations itself.

In a typical holdco/opco structure, the operating company earns business income and, rather than retaining all of that income in the opco, pays tax-free inter-corporate dividends up to the holding company. The funds then sit in the holding company, sheltered from the operating risks of the active business.

Under section 112 of the Income Tax Act, dividends paid between connected Canadian corporations are generally deductible to the recipient corporation — meaning the holdco does not pay tax on dividends received from the opco. This is a fundamental feature of the Canadian corporate tax system.

Why Incorporated Professionals Consider a Holdco

1. Asset protection

Retained earnings sitting inside an operating company are exposed to the liabilities of that business. A lawsuit, a contract dispute, or a regulatory issue could put those funds at risk. Moving excess cash up to a holding company — which has no direct operating exposure — places those assets at a distance from the operating risks of the business. Note that proper legal advice is essential here; a CPA can address the tax mechanics, but the structural protection requires input from a corporate lawyer.

2. Tax deferral on passive income

The passive income threshold rules introduced in 2018 reduce the small business deduction (SBD) for CCPCs that earn significant passive investment income inside the corporation. Specifically, the SBD begins to phase out when a CCPC and its associated corporations earn more than $50,000 in passive income in the prior year, and is fully eliminated at $150,000.

When passive income is earned inside the opco, it can affect the small business deduction available on active business income. Holding excess investment assets in a separate holdco — which may not be an associated corporation depending on the structure — is one approach professionals use to manage this. This area is complex and fact-specific, and structure should be designed with CRA association rules in mind.

3. Estate and succession planning

A holding company can simplify the transfer of business interests between generations or between shareholders. Share structures, estate freezes, and other succession mechanisms are often easier to implement in a holdco context than in a single operating corporation.

The Passive Income Threshold: A Key Consideration

Since 2018, the federal small business deduction — which allows CCPCs to pay a lower corporate tax rate on the first $500,000 of active business income — is reduced based on passive income earned by the corporation and associated corporations in the prior year.

For every dollar of passive income above $50,000, the SBD limit is reduced by $5. The SBD is fully eliminated at $150,000 of passive income.

This means a professional corporation with significant retained earnings invested in passive assets may lose some or all of the benefit of the small business deduction — paying the general corporate rate on active income instead. Structuring accumulated wealth thoughtfully, and understanding which corporations are "associated" under the Income Tax Act, is an important part of this planning.

What a Holdco Does Not Do

A holding company does not eliminate tax. Income earned inside the holdco is subject to corporate tax. When funds are ultimately distributed to the shareholder personally, dividend taxes apply. The benefit is primarily one of deferral — tax is paid later, and the funds can compound inside the corporation in the meantime.

A holding company also adds administrative cost: separate corporate filings, separate financial statements, and additional complexity. For a corporation with modest retained earnings and no near-term succession or asset protection concerns, that cost may not be justified.

When the Conversation Usually Starts

Most incorporated professionals begin to think about a holding company when their operating corporation is consistently generating more profit than they personally need — meaning retained earnings are building up. The question of what to do with those earnings, and how to protect and grow them, is typically where holdco planning enters the picture.

When to Speak With a CPA

Holdco structures are not something to set up based on a general article. The right structure depends on the nature of your income, your associated corporation situation, your province of residence, your estate planning goals, and your personal financial position. These conversations are best had before retained earnings have been accumulating for years without a plan.

Rotaru CPA works with incorporated professionals at all stages to think through corporate structure — not just at tax time, but as circumstances evolve.
