Health spending accounts for owner-managers: the rules that make them real

A health spending account is one packaging of a private health services plan, and where it qualifies the arithmetic is clean: your corporation deducts what it pays out, and the money reaches you without appearing on a T4. Whether it qualifies has almost nothing to do with the account and everything to do with the plan behind it — limits written down before the year starts, expenses confined to what the CRA already treats as medical, and a real employment relationship for the coverage to attach to. An owner who is the only person in the plan is the hard case, and it is the case most of these are sold into.

The account is the plumbing. The plan is what gets read.

What the CRA is reading when it reads your plan

A private health services plan is a plan in the nature of insurance — an undertaking, for consideration, to indemnify someone against defined health costs. Insurance has limits fixed before anyone knows what the year holds, and a real chance it pays out more or less than it cost. The paperwork follows. Each participant’s annual allotment is set in writing before the coverage period begins, not in March against a shoebox of receipts. Classes can carry different limits where the classes are defensible on job grounds, not on who is related to whom. And the allotment has to behave like coverage: an amount that reaches the participant whether or not claims are made is remuneration, whatever the document calls it.

The mechanics are ordinary. You pay the dentist. An administrator checks the claim against the eligible-expense list and your remaining allotment, the corporation funds the reimbursement and a fee on top, and deducts both as a cost of employing people. Nothing lands on your T4, the slip reporting employment income — the same logic that keeps a documented home-office reimbursement off your slip.

The owner-only problem

This is the condition the sale skips over: the exclusion from your income works because you receive the coverage as an employee. Where the only participant is the person who controls the corporation, the CRA can read it as received as a shareholder instead — and a shareholder benefit is taxable to you with no offsetting corporate deduction. Both halves go at once, on reassessment, years after the claims were paid.

The practical test is comparative: would the corporation give the same coverage, on the same terms, to an arm’s-length employee doing the same job? A corporation with two people in the plan on written class terms answers with a payroll register. A corporation whose only participant owns it answers with an assertion. Putting a spouse or an adult child on the payroll does not settle it either — the reasonableness test that governs their salary reaches their coverage on the same logic.

One prerequisite sits under all of it: a plan for employees needs employees, and an owner who takes only dividends may not be one. If the corporation has never opened a payroll account and you have never had a T4, there may be nothing for the coverage to attach to — a quiet input into the salary-and-dividend mix rather than a decision made after it.

Reasonableness is the softer test, and nobody designs for it

A plan that clears all of that is still deductible only so far as the cost is reasonable — read generally against the whole compensation package, not the allotment alone. A coordinator paid a market wage with a modest allotment is unremarkable. An owner drawing very little salary and carrying a very large allotment is a compensation decision wearing a plan’s clothes. The CRA has published no number and neither will we — but the amount is testable, the test is comparative, and it is asked years later against limits you set in advance. Sizing the allotment to what your family spent last year is what most often fails it: it removes the uncertainty the definition depends on.

What the plan is allowed to pay for

Confine covered expenses to what would qualify as medical expenses on a personal return and the plan stays inside its definition. The CRA publishes that list and revises it, which is the honest answer to every “does this count” question. Read the current list, not a brochure.

The broad shape is stable. Prescription drugs · dental work · prescription eyewear · services from a defined set of authorized practitioners · premiums paid to another private health or travel plan. Which practitioners qualify is set by province, so the same treatment can be covered for one employee and not another. Out are most of the things people want in: over-the-counter purchases, most cosmetic procedures, gym memberships and general wellness spending — the last of which is often sold in the same conversation as a health plan. Non-qualifying items are generally a taxable benefit at minimum, and running them through the same plan puts its status in play.

Against paying the dentist yourself

Pay medical costs personally and the relief is the medical expense tax credit on your T1 — non-refundable, computed at the lowest federal rate, and applied only to the part of eligible expenses exceeding a threshold: the lesser of a fixed indexed amount and a percentage of your net income. Each feature costs you. Non-refundable means it reduces tax owing and stops. Lowest rate means a dollar of expense returns a fraction of a dollar. A threshold means the first slice returns nothing.

That is the smaller half of the gap. To hand the dentist a dollar personally, the corporation first has to pay you enough that a dollar survives your marginal rate. The plan route skips that step. The credit does not disappear, it shrinks — expenses no plan covered still go on the return, where a family’s are generally combined on one spouse’s over a 12-month period ending on any date in the year.

The costs against it are real and small. The administration fee, generally a percentage of claims, carries GST/HST, and some provinces apply a premium or sales tax as well; below a certain spend the fee costs more than the deduction returns. And Quebec treats employer-paid contributions to a private health plan differently from the federal treatment, so a Quebec-resident owner should not assume the federal answer is the whole one.

A worked example: C$2,400 of claims, two ways

Illustrative, round numbers, December 31 year-end. An engineering consultant works through her corporation and employs one arm’s-length coordinator. Before the plan year starts she sets two classes in writing: C$3,000 of annual coverage for the owner-employee class, C$1,500 for the staff class.

Her family’s qualifying claims come to C$2,400 — C$1,800 of orthodontics, C$400 of eyewear, C$200 of prescriptions. Each is submitted, checked against the eligible list and her remaining allotment, and reimbursed. The corporation funds C$2,400 plus the fee, deducts both against active business income taxed federally at 9% on the first C$500,000 for an eligible CCPC in 2026 plus its provincial rate, and issues her no slip. The C$600 of unused allotment is not paid out — the feature, not the flaw.

Outside a plan the same C$2,400 starts further back. She has to draw enough salary or dividend for C$2,400 to survive her personal rate, so the corporation parts with meaningfully more to settle identical bills. Then only the part above the threshold enters the credit, at the lowest rate. The difference is not really deduction versus credit — it is the draw she never had to make. And the coordinator’s C$1,500 class is no rounding detail. It is most of what makes the owner’s C$3,000 look like a plan.

Reimbursing yourself is not a plan

The common failure has no plan in it: the owner pays a medical bill from the corporate account, books it to a health spending account, and stops there. No administrator, no adjudication, no limits — generally a shareholder benefit, taxable to him, with no corporate deduction, and if it is booked against what the company owes him instead, it lands in the shareholder-loan account.

What Cadence does

We neither sell nor administer these plans; an administrator does. We decide whether one belongs in your file before you sign — whether there is an employment relationship for it to attach to, whether your payroll supports a class structure that means something, and what the allotment can be without turning a benefit question into a compensation one. Then we read the plan against your last two years of medical spending and say where the fee eats the deduction.

After that it is maintenance, which is where these fail: limits re-set in writing before each plan year, the expense list re-checked when the CRA revises it, and the arrangement re-examined the year you hire, lose your last arm’s-length employee, or change your compensation mix. That work sits inside year-round tax planning and is included in the year-round packages rather than in annual compliance. It comes up most often with consultants and professional-services owners, for the obvious reason: they are usually the whole payroll.
