T4 and Payroll Implications of HSA Benefits for Owner-Employees

The Income Tax Act has no entry for "Health Spending Account." The CRA classifies these arrangements as Private Health Services Plans, or PHSPs, and that classification, not the HSA label a provider puts on a brochure, is what makes the reimbursement tax-free. Paragraph 6(1)(a)(i) of the Income Tax Act is the actual statutory hook: it excludes qualifying PHSP benefits from employment income. When a plan meets every PHSP requirement, the employee receives reimbursements free of federal and provincial tax, the amounts don't appear on a T4 slip, and CPP and EI deductions don't apply. On the employer side, every dollar put into a compliant plan counts as a fully deductible business expense, which stands in sharp contrast to salary, where both payroll taxes and income taxes take a bite before the employee sees a cent.

The PHSP label does two jobs at once. It's the gate that lets the tax-free treatment through, and it's the source of an ongoing obligation. A plan has to meet CRA's criteria not just on the day it's set up, but every time a claim is paid. Treat PHSP status as something maintained, not something earned once and filed away.

Qualifying as a PHSP

PHSP qualification comes down to a handful of structural requirements. Missing any one of them turns what looked like a tax-free reimbursement into taxable income, often well after the money has already changed hands.

The plan has to be employer-funded. Employees cannot put their own after-tax dollars into an HSA the way they might into a similar personal account elsewhere. Eligible staff need to fall into clearly defined benefit classes. There can be no cash-out option: an employee can't pull unused funds out as cash or take them as a top-up to salary. If that door is open, CRA can reclassify the whole benefit as a taxable allowance, even for claims that were otherwise legitimate.

The plan also needs to be documented formally, either through a third-party administrator or a written internal policy, and reimbursements need to flow through the corporation rather than straight out of an owner's personal account. Third-party administration at arm's length is what CRA expects to see, and it does double duty: it also protects the plan from the "self-administered" red flag that audit reviews key in on. And where an HSA reimburses something CRA treats as taxable, fitness equipment being a common example, that amount has to be added to the employee's pay and reported on the T4 like any other taxable benefit.

These are the baseline conditions every plan has to clear. Owner-employees face a tougher version of this same test, and that's where the real complexity in this area starts.

The employment relationship as the gateway condition for incorporated owners

For an incorporated business owner, PHSP access starts with one question: is this person on payroll, drawing T4 employment income? Without that, CRA doesn't see an employment benefit at all. It sees a shareholder receipt.

The logic traces straight back to the statute. A PHSP is, by its nature, an employee benefit. Paragraph 6(1)(a)(i) excludes PHSP benefits from employment income, and that provision only does work when employment income exists. Compare that to section 15(1), which taxes shareholder benefits as income to the shareholder and denies the corporation any deduction for them. Running an HSA through a shareholder who has no T4 income can cause the same dollars to end up taxed twice: once because the corporation can't deduct them, and again because the shareholder has to report them as income.

The practical requirement for an incorporated owner is to be on payroll and to draw a regular, documented salary. That single fact ties the HSA decision directly to whether the owner should take salary or dividends, a choice the later sections of this piece return to directly. An HSA strategy for an incorporated owner can't be designed in isolation from that compensation choice. The two decisions move together.

Being close to an employment relationship isn't the same as having one. CRA looks past the corporate structure on paper and asks how the owner is actually paid, in practice, on an ongoing basis.

Employment Benefits and Shareholder Benefits

CRA's test for whether a benefit arrived by virtue of employment or by virtue of share ownership asks whether someone in a comparable arm's-length role, at a similarly sized company, would receive similar benefits. That test gets harder to pass as the company gets smaller.

Where equivalent PHSP coverage reaches every employee, including those who happen to hold shares, CRA generally treats the shareholder's benefit as flowing from employment. A one-person corporation sits at the opposite end of that spectrum and carries the highest risk, since CRA's general position treats a sole shareholder-employee as receiving PHSP benefits in their capacity as a shareholder unless they can show that employees who are not shareholders, doing similar work at another company of similar size, receive similar benefits under a similar plan, a demanding standard that asks the sole owner to prove a point by comparison to a market they aren't part of.

CRA's own guidance leaves room on the other side of that line too. Where the individual is actively engaged as an employee and the PHSP benefits are reasonable and consistent with what an arm's-length employee doing similar work would receive, CRA accepts that the benefit arises from employment.

The Spicy Sports Inc. case shows what that line looks like when a plan fails it. The company had more than 30 employees, but its cost-plus PHSP was available only to shareholder-employees. The Tax Court found against the taxpayer for that reason. The CRA's own internal technical interpretation on the case concluded it would be unlikely that the company would have entered into that same cost-plus arrangement with an arm's-length key employee. The plan didn't fail because of the size of the claims or the nature of the expenses reimbursed. It failed because its use was restricted to shareholders in a company where dozens of non-shareholder employees existed and received no comparable plan.

The cost-plus plan problem for sole shareholder-employees

Clearing the employment-relationship test is only the first hurdle. A cost-plus plan structure, which is how many small incorporated owners set up their HSA, brings a second and separate layer of scrutiny, one that applies regardless of how strong the employment relationship otherwise looks.

A cost-plus plan works by having an administrator agree to reimburse an employee, and in these cases a sole employee-shareholder and their household, for actual medical expenses, while the administrator collects only the amount reimbursed plus a fee for handling the paperwork. CRA's position on this structure was confirmed at the 2022 CALU conference, in document 2022-0928901C6: a cost-plus plan built around a sole employee-shareholder does not qualify as a PHSP, because it would likely not constitute a plan in the nature of insurance. No risk passes to the administrator. The administrator simply passes through the reimbursed amount and adds a handling fee, with no risk on its books.

The underlying concern is straightforward. A sole employee-shareholder running personal medical expenses through their own corporation, with no actual transfer of risk to a third party, doesn't have the insurance character CRA requires of a PHSP. Some practitioners push back on this position, pointing out that the Income Tax Act itself contains no explicit "insurance risk" test for PHSPs. That requirement comes from CRA's administrative policy, not from legislation.

That debate doesn't change the practical exposure for a business owner today. Whether or not the cost-plus plan qualifies as a PHSP, a sole employee-shareholder who receives these benefits in their capacity as a shareholder still has to include them in income under subsection 15(1). Challenging CRA's administrative position is a legal argument that would need to be made in front of the Tax Court, and until that happens, the plan's structure determines the tax result.

What appears on a T4 across different HSA scenarios

The T4 is where the legal analysis turns into a payroll reality. Whether a reimbursement shows up on that slip is a direct readout of whether the plan met PHSP requirements, and the reporting rules for non-compliant arrangements catch a lot of small business payroll administrators off guard.

A PHSP-compliant HSA reimbursement doesn't appear on the T4. It isn't subject to CPP or EI, and no payroll deductions apply.

A medical reimbursement paid outside a PHSP is a taxable benefit. It has to be reported in Box 14 of the T4 using code 40, and CPP applies to it.

A Wellness Spending Account (WSA) reimbursement is reported as employment income in Box 14. It's subject to CPP, and generally subject to EI when paid as a cash reimbursement, though EI insurability under CRA's T4130 guide depends on whether the benefit is paid in cash or delivered as a non-cash or near-cash benefit. WSA reimbursements fall outside PHSP treatment because they cover non-medical expenses, like gym memberships or wellness classes, that PHSPs aren't built to cover.

A shareholder benefit assessed under section 15(1) doesn't appear on the T4 either; it's included in the shareholder's personal income, on a different line of the tax return. That separation trips up incorporated owners: no T4 entry can read, incorrectly, as no tax consequence, when in fact a section 15(1) inclusion is sitting on the personal return.

Where employees contribute to a PHSP themselves, employers have to report those contributions using code 85 on the T4 (or code 135 on a T4A for former employees). Employees use that reported amount to claim qualifying medical expenses on their own return, and if it isn't reported, CRA may come back and ask the employee for supporting documentation directly.

Quebec adds its own reporting layer. Employer contributions to a PHSP that count as a taxable benefit go in Box J of the RL-1. Where the benefit is a shareholder benefit rather than an employment benefit, it goes instead in Box O, using code RO. Ontario employers get a narrower but useful break: HSA contributions there are exempt from the Employer Health Tax.

Common audit triggers CRA looks for when it reviews an owner-employee HSA

CRA's review of an owner-employee HSA tends to focus on a small, consistent set of structural red flags, and most of them trace straight back to the employment-versus-shareholder distinction already covered. Recognizing them is less about fear and more about knowing which specific facts make a given plan more or less defensible.

The clearest trigger is no T4 salary for the person making the claim. If the owner's only compensation is dividends, the PHSP deduction has no legitimate foundation to stand on, no matter how the plan itself is documented. Self-administered plans without proper paperwork are another weak point: a plan with no written policy, no formal claims process, and no third-party administrator is exposed on two fronts at once, the "insurance element" test and the arm's-length comparison test. Benefit levels that are disproportionate to the owner's compensation draw scrutiny too, independent of how the plan is structured, if the limits exceed what an arm's-length employee in a similar role would reasonably receive.

Exclusive or near-exclusive use by the shareholder is the Spicy Sports Inc. pattern, and it's what auditors look for as evidence that benefits flowed from share ownership. Claims for ineligible expenses, items outside Section 118.2(2) of the Income Tax Act, or wellness costs that belong in a WSA rather than an HSA, signal that the plan isn't actually operating as a PHSP in practice, whatever its paperwork says.

A defensible plan looks different on every one of these points. It has documented T4 salary for the owner-employee, written plan terms, administration handled by an arm's-length third party, benefit limits that match what a comparable arm's-length employee would receive, and a clean line between eligible medical expenses and any wellness spending kept in a separate account.

The salary-versus-dividend decision and its effect on the HSA outcome for incorporated owners

Everything in the preceding sections funnels back to one choice an incorporated owner makes before any HSA paperwork gets filled out: how to draw compensation from the corporation. That decision is the upstream factor that shapes whether the HSA works as intended.

Salary creates T4 employment income, and that income is what establishes the employment relationship CRA requires before PHSP treatment applies. Dividends don't create that relationship, regardless of how large they are or how long the owner has been running the company. Salary carries other downstream effects that matter here too: it builds RRSP contribution room, it generates CPP entitlement, and it gives the owner a concrete income figure against which reasonable PHSP benefit levels can be benchmarked when CRA asks whether the plan looks like something an arm's-length employee would actually receive.

A sole shareholder-employee who draws enough salary to establish a credible employment relationship, sets up the HSA with genuine arm's-length administration, keeps benefit limits in line with comparable arm's-length employment, and documents the plan properly stands in a materially stronger position than one who skips these steps. Neither owner is guaranteed a smooth outcome if CRA opens a file. But the owner who has built salary, documentation, and arm's-length structure into the plan from the start has something to point to. The owner who hasn't is relying on the plan never being asked to prove itself.
