Arm's Length Requirement for PHSP Shareholder-Employees

A PHSP can pay out the exact same dollar amount to two shareholder-employees in identical corporations, and one gets it tax-free while the other pays full income tax on it. The difference isn't the plan. It's whether the CRA decides the person received that dollar as an employee or as a shareholder. This piece unpacks that distinction by tracing the arm's length logic that produces it.

How the ITA defines a PHSP and the significance of the insurance character requirement

Section 248(1) of the Income Tax Act defines a private health services plan as either a contract of insurance for hospital and medical expenses, or a plan of medical or hospital care insurance. That sounds simple enough, but the CRA's own guidance, IT-339R2, issued back in August 1989, spells out five things a plan needs to actually look like insurance:

An undertaking by one person, to indemnify another person, for agreed consideration, against a loss or liability, where the triggering event is uncertain.

That last part, the uncertainty, is doing more work than it looks like. Employees may or may not get sick. They may or may not need a crown, physio, or new glasses in a given year. If they don't use the benefit, the money doesn't roll over into their pocket, it gets forfeited. That forfeiture is what makes the arrangement resemble insurance rather than a savings account with a tax exemption stapled on.

Without genuine uncertainty and without real forfeiture, the CRA doesn't see insurance. It sees disguised compensation wearing an insurance costume. And a plan the employer can cancel whenever it feels like, at its sole discretion, fails the same test. The CRA addressed related insurance character concerns in 2022-0928901C6, part of its response to CALU's Q10, where it concluded that a self-insured HSA for a sole employee-shareholder would likely not constitute a plan in the nature of insurance.

Shareholders run into trouble right here. The tighter the control a shareholder has over both sides of the deal, the payer and the payee, the harder it gets to argue real risk transfer happened at all. That's the whole reason the arm's length concept exists in this context: it's a proxy for genuine separation between the party bearing the risk and the party covered by it.

Post-2015, the CRA's position is that a plan qualifies as long as "all or substantially all" premiums (for insured plans) or benefits paid (for self-insured plans) relate to expenses eligible for the Medical Expense Tax Credit. "Substantially all" means 90% or more. Stray much past that cushion on ineligible expenses, and the plan's status as a PHSP is at risk.

What the employee-versus-shareholder distinction requires in practice

The Income Tax Act itself lays out the stakes. Subparagraph 6(1)(a)(i) excludes PHSP benefits from employment income when they're received in the capacity of an employee. Section 15(1) does the opposite: benefits received in the capacity of a shareholder are taxable to that individual. Same plan, same benefit, opposite tax outcomes, depending entirely on which hat the CRA decides the person was wearing.

CRA Technical Interpretation 2003-0050541E5, corroborated by taxtips.ca, points to several conditions that support the employee side of that line:

Active, regular, ongoing engagement in the business. Evidence of an actual employment relationship with the corporation. And a benefit level that's reasonable, meaning consistent with what an arm's length employee doing similar work would get.

Compensation structure matters a lot here, maybe more than people expect. If a shareholder takes nothing but dividends, that's a red flag the CRA can point to when reclassifying the PHSP payout as a shareholder benefit under section 15(1). To be fair, the CRA hasn't issued a hard rule requiring T4 salary. taxtips.ca notes there's no clean, definitive answer on record. Still, the conservative move, and the one most advisors recommend, is to have at least some portion of compensation flow through as T4 income. It corroborates the employment relationship instead of leaving it to argument alone.

The employment contract itself needs teeth too. It should name the PHSP as a term of employment, obligate the corporation to reimburse eligible claims, and limit the employer's ability to yank coverage or change it on a whim without notice.

And the benefit size can't be reverse-engineered from what the shareholder wants to spend on orthodontics this year. It has to be benchmarked against what a comparable arm's length employee in a similar role, at a similar company, would reasonably receive.

Why corporations with only shareholder-employees face a harder test

A plan available only to shareholders invites an obvious argument: the benefit flows from ownership, not from the job. CRA guidance makes this point directly. But a plan open to all employees, even ones who happen to also be shareholders, can still hold up, because availability isn't restricted along ownership lines.

The cleanest fix, when it's available, is having non-shareholder employees participate in the same plan. That removes the ambiguity almost entirely. Small operations and single-person corporations don't always have that option, though, and when they don't, the entire evidentiary burden shifts onto the employment contract and the compensation structure. There's no other backstop.

Incorporation gives the shareholder a separate legal identity from the business, and that separation is exactly what makes a genuine employment relationship possible in the first place. But it's a necessary condition, not a sufficient one. Incorporating doesn't prove employment on its own, the facts on the ground still have to support it.

Incorporated businesses don't face the statutory dollar caps that sole proprietors do. There's no fixed formula here. The test is reasonableness, benchmarked against comparable arm's length arrangements, even in cases where no arm's length employee actually works at the company.

The sole shareholder-employee: CRA's current position after its earlier shifts

If there's one scenario that keeps tax advisors up at night on this topic, it's the sole shareholder who is also the sole employee. And the CRA hasn't exactly been consistent about it.

Back in March 2006, document 2005-0163771E5 showed the CRA willing to permit a plan for a sole shareholder-employee and family members, under certain conditions, marking the permissive era. That was the permissive era.

Then came 2014-0521301E5, which flipped the framing: where the sole shareholder is also the sole employee, the CRA said it would treat the benefits as received in the capacity of shareholder, unless that person could show that non-shareholder employees with similar duties, at a similarly sized corporation, receive similar benefits under a similar plan. A tough bar. Finding a truly comparable arrangement to point to isn't easy in practice.

September 2017 brought another shift. Document 2017-0703871C6 saw the CRA softening again, acknowledging it was "likely" that a sole employee-shareholder would be reimbursed for the full amount allocated each year under such a plan. Not a green light exactly, but a warmer tone.

Then 2022-0928901C6, the CALU Q10 response, reversed course once more. The CRA concluded that a self-insured HSA covering a sole employee-shareholder and family members would "likely not constitute a plan in the nature of insurance" and therefore wouldn't qualify as a PHSP at all.

The logic behind that 2022 stance goes back to the insurance character requirement itself. When one person controls the corporation and is also the only person the plan benefits, there's no real transfer of risk happening. It's the same person on both sides of the transaction, just paying personal medical bills through a corporate structure instead of a personal bank account.

This concern is widely reflected in Canadian tax practice: where an incorporated professional is the sole employee of their own professional corporation, the tendency is to treat PHSP benefits as flowing from shareholding, which makes them taxable to the individual.

The pattern across these rulings isn't a straight line, it zigzags. Advisors working with sole shareholder-employees should treat this scenario as elevated risk, full stop, and document the employment basis as thoroughly as the facts allow.

Structural safeguards that strengthen the employment-capacity argument

None of this means a sole shareholder-employee is locked out of PHSP eligibility. It means the structure around the plan has to do real work.

For exactly this situation, sound practice calls for specific employment contract language: an explicit reference to the HSA as a term of employment, a stated obligation on the corporation to reimburse all properly submitted eligible claims up to the plan limit, and a restriction on the employer's ability to modify or cancel the plan at will or without advance notice.

These aren't boilerplate additions. They create an actual, enforceable obligation running from the corporation to the individual, and that obligation is the structural ingredient that gives the plan its insurance character in the first place. Without it, there's nothing binding the corporation to pay, which means there's no risk being transferred at all.

Compensation mix still matters here too. Taking at least a portion of pay as T4 salary corroborates the employment relationship, even without a formal CRA rule demanding it.

Benefit levels need discipline as well. For a sole shareholder-employee, the coverage amount chosen should be something that could be defended as what a non-shareholder employee, doing similar work at a similarly sized company, would plausibly receive. That's the benchmark test straight out of 2014-0521301E5, and it remains the standard against which benefit levels are measured.

Forfeiture has to be real, not theoretical. If unused balances carry forward indefinitely, or get paid out whenever the plan winds down, that undermines the insurance character right at its foundation. Structuring the plan so unused amounts are genuinely lost at period-end reinforces the arm's length, insurance-like nature of the whole arrangement.

And using a third-party administrator instead of self-administering claims adds a layer of separation between the corporation and the person benefiting from the plan, consistent with how employer-sponsored benefit plans actually function in the arm's length world.

How the arm's length requirement works differently for unincorporated businesses

Sole proprietors face a completely different problem, because the business and the owner are legally the same person. The business and the owner are legally the same person. There's no separate entity capable of "insuring" the owner against the owner's own expenses, because insuring yourself against yourself isn't insurance at all.

That means the plan can't satisfy the insurance test unless it covers at least one other person, someone the proprietor is genuinely indemnifying, not just themselves.

An arm's length employee, for this purpose, can't be related by blood, adoption, or marriage (including common-law), can't be a business partner, and can't be a temporary or seasonal hire. They need to be full-time and continuously employed for at least three months to count as a "qualified employee." Even one part-time arm's length employee can open the door, so long as the employment relationship is genuine and not just paperwork.

From there, a 50% threshold kicks in. If half or more of the employees are arm's length, the sole proprietor's deduction gets capped at whatever equivalent coverage costs for each qualified employee, no richer plan for the owner than what the staff gets.

If fewer than half the employees are arm's length, the deduction cap drops to a fixed annual number: $1,500 per insured adult and $750 per insured child under 18. For a family of four, that tops out at $4,500 a year.

There's also an income test layered on top: either more than half of total personal income has to come from the sole proprietorship, in the current year or the prior one, or income from every other source combined has to be $10,000 or less.

And if there are no arm's length employees at all? The plan simply doesn't qualify. The CRA's position on this is consistent, confirmed across its published guidance. Some providers have marketed these plans to sole proprietors without any employees anyway, but the CRA has been explicit that doing so doesn't meet the requirements of the Income Tax Act.

That's the sharp contrast with incorporation. An incorporated shareholder-employee doesn't need arm's length employees on staff to qualify for a PHSP, because the legal separation between the corporation and the individual makes genuine employment structurally possible even in a company of one. The sole shareholder-employee still faces the heightened scrutiny covered above, but the door isn't closed the way it is for an unincorporated sole proprietor working alone.

What a compliant PHSP setup looks like for an incorporated shareholder-employee

Four elements, taken together, build the strongest case for employment capacity: active and ongoing engagement in running the corporation, an employment contract that names the PHSP as a binding term and limits the employer's termination rights, at least some compensation taken as T4 salary, and a benefit level pegged to what a comparable arm's length employee would receive elsewhere.

Third-party administration adds real structural weight too. When an arm's length administrator handles claims adjudication, that separates the decision-making function from the shareholder-employee who stands to benefit, which lines up with how the CRA expects genuine insurance arrangements to operate.

Annual reporting and reimbursement by electronic transfer, rather than informal cash or in-kind arrangements, creates a documented trail showing the plan functions as an employer-sponsored benefit rather than a personal expense account with a different name on it.

Expense eligibility still has to hold up on its own terms, too: at least 90% of what's reimbursed needs to qualify under the Medical Expense Tax Credit rules, reflecting the CRA's post-2015 position on "all or substantially all.""

For incorporated professionals and small business owner-operators, a pay-as-you-go structure administered at arm's length, with a per-claim fee (an 8% administration charge on approved claims is one common structure, with no setup or annual fees) rather than a fixed premium, is a fairly clean way to meet the insurance character test while tying cost directly to actual usage instead of speculative coverage limits.

None of this replaces professional judgment. Every one of these factors, business structure, the actual employment relationship, how the plan is designed, and the CRA's current interpretive position, has to be weighed together by a tax professional reviewing the specific facts.
