Do You Actually Need a Holding Company?

Almost every article you’ll find on holding companies was written for owner-managed businesses. It describes a structure where a holding corporation sits above your operating company, receives dividends from it tax-free, and holds your investments at arm’s length from business creditors.

That structure is real, and it works. It’s also unavailable to a large share of the professionals who read about it, for reasons the articles rarely mention.

If you run a professional corporation in Ontario, the first question isn’t whether a holding company would help. It’s whether your regulator will let you have one.

Your college may not permit it

Ontario professional corporations are governed by the Business Corporations Act and by the rules of each profession’s regulator — and the regulators do not agree with each other.

The Law Society of Ontario permits a holding corporation to hold shares of a law professional corporation, provided the holdco’s shareholders, directors and officers are all licensees, and its articles restrict its business to holding those shares. Family members cannot hold shares in that holdco.

The College of Physicians and Surgeons of Ontario does not permit holding corporations to own shares of a medicine professional corporation. Neither does the Royal College of Dental Surgeons of Ontario for a dentistry professional corporation. In both cases, non-voting shares may be held by a spouse, child or parent of a voting shareholder, or in trust for minor children — but a corporation cannot sit above the practice.

Other regulated professions set their own rules, and they change. Before anyone drafts articles, the answer needs to come from your own college, in writing.

This is the step that gets skipped. A structure recommended in good faith by someone working from general corporate tax principles can put a certificate of authorization at risk.

The passive income problem a holding company does not solve

This is the most common misunderstanding we see, and it costs real money.

Where a corporation earns passive investment income above certain thresholds, its access to the small business deduction begins to shrink. Owners who learn this often reach for the same fix: move the investments into a separate corporation, so the operating company’s own passive income stays low.

It doesn’t work that way. Associated corporations are tested together. Adjusted aggregate investment income is aggregated across the associated group, and the business limit is shared. A holdco that is associated with your professional corporation — which it will be, if you control both — brings its investment income back into the same calculation.

There are structures where the grind can be managed. Moving the portfolio one corporation to the left is not one of them.

What a holding company does earn its keep for

Creditor protection. Retained earnings sitting inside the operating company are exposed to its liabilities. Paying them up to a holdco as an inter-corporate dividend moves them out of reach of most operating risk — though not, it’s worth saying plainly, out of reach of your personal professional liability.

Preserving the capital gains exemption. The lifetime capital gains exemption on qualifying small business corporation shares is worth roughly $1.25 million per individual, but it comes with asset tests: broadly, 90% of assets used in an active business at the time of sale, and 50% throughout the preceding 24 months. Investments accumulating inside the operating company erode that. Moving them out — purification — keeps the shares qualifying. Because of the 24-month test, this is work that has to happen well before a sale, not during one.

Succession and estate planning. An estate freeze locks in today’s value for you and lets future growth accrue to the next generation. A holding company is often where that gets structured. Doing it early, before there’s significant value to freeze, is materially cheaper.

Multiple shareholders with different needs. Where a practice has several owners drawing different amounts on different timelines, individual holdcos let each shareholder control their own distribution timing.

The dividends aren’t automatically tax-free

Inter-corporate dividends between connected Canadian corporations generally flow without immediate tax, which is what makes the structure work. But subsection 55(2) can recharacterize a dividend as a capital gain where it exceeds safe income, and Part IV tax applies in circumstances that catch people out.

None of this makes a holding company a bad idea. It makes it a structure that needs a calculation and a paper trail, not a template.

What it costs

A second corporation means a second T2 return, a second year-end, its own financial statements, annual corporate filings, and the legal work to set it up and keep the articles compliant. Realistically that’s a recurring annual cost on top of a one-time setup cost.

Against that, the benefits are mostly contingent — creditor protection matters if something happens, the capital gains exemption matters if you sell, the freeze matters on succession. Contingent benefits are still worth paying for. They’re just harder to weigh, which is why the honest version of this conversation starts with your actual retained earnings and your actual timeline rather than a list of advantages.

If there isn’t much accumulating inside the corporation, there usually isn’t much to protect, and the structure is premature.

A note on the workarounds

Because the restriction on holdcos frustrates legitimate planning, workarounds circulate — most commonly a short-duration arrangement in which a holding corporation is briefly a shareholder, a dividend is paid, and the shareholding is unwound.

We don’t treat these as routine. The regulatory position is not settled, the outcome depends on facts, and the downside sits with the certificate of authorization rather than with the tax return. If a client wants to consider one, that’s a conversation involving their lawyer and, where appropriate, their college — not a step taken quietly at year-end.

How to decide

Four questions, in order:

1. Does your regulator permit it? If not, the rest is academic and the planning goes in a different direction.
2. How much is actually accumulating in the corporation each year, after what you draw?
3. Is a sale of the practice or its assets plausible in the next several years?
4. Is there a succession question — family, partners, retirement — that’s going to need answering anyway?

If the answer to the first is yes and at least one of the others is substantial, the structure is worth modelling. If not, the money is better spent elsewhere.
