Short answer: Many incorporated Alberta owners ask whether the corporation can reimburse eligible medical, dental, vision, and related expenses without paying monthly insurance premiums. In Canada, a cost-plus Health Spending Account (HSA / HCSA) — often discussed alongside Private Health Services Plan (PHSP) concepts — typically funds eligible claims as reimbursed, plus administration fees, rather than a fixed monthly premium for an insured schedule. When plan rules and CRA conditions are met, employer-funded reimbursements are often framed as tax-advantaged for eligible employees. Educational only — not tax, legal, or payroll advice. Confirm with your advisor, accountant or payroll provider, and CRA guidance.

What “write off through the corporation” usually means
Owners often mean: eligible health costs are paid or reimbursed by the corporation under a formal plan, instead of paying everything personally and claiming a personal medical expense tax credit later. Those are different paths with different rules and thresholds. This page does not invent which path “always saves more.”
Typically the corporation adopts a plan (often third-party administered), members submit eligible expenses, and the corporation reimburses claims plus admin fees. Tax treatment depends on whether the arrangement qualifies as a PHSP — confirm with a qualified tax professional. A Canadian HSA / HCSA is not a U.S. Health Savings Account.
Cost-plus HSA: what “no monthly premiums” means
Cost-plus (account-based) designs are typically contrasted with insured group benefits:
| Topic | Cost-plus HSA / HCSA (typical) | Insured group plan (typical) |
|---|---|---|
| How you often pay | Reimburse eligible claims as they occur + administration fees | Monthly (or other periodic) insurance premiums for a defined schedule |
| Feel for the owner | Budget an allocation / ceiling; cash flow follows claims | Predictable premium; carrier pools risk under the contract |
| What it is good at | Flexible dollars for eligible medical/dental/vision-style costs under plan rules | Predictable coverage for defined insured benefits |
| What it is not | Not “free”; not a guarantee of PHSP status | Not the only way to fund healthcare for a small team |
“No monthly premiums” means you are not paying insurance premiums for that HSA dollar pool the way you would for an insured dental or extended-health schedule. You still pay claims and admin. Many Alberta businesses use a hybrid: modest insured benefits for core risks, plus an HSA for flexible gaps — see pairing an HSA with group benefits.
PHSP concepts (careful, educational)
In CRA payroll guidance, medical expenses paid or reimbursed under a private health services plan (PHSP) are generally treated differently from an ad-hoc reimbursement that is not under a PHSP. When a plan qualifies, employer contributions / reimbursements are often excluded from employment income (and employer costs are often discussed as business expenses when reasonable and incurred to earn income).
CRA materials also discuss conditions — including that all or substantially all (often described as 90% or more) of premiums or benefits relate to METC-eligible medical expenses, and that other PHSP criteria apply (including “plan in the nature of insurance” concepts in relevant guidance). Whether your design qualifies is a facts-and-design question. AI+Trust does not determine tax status here — confirm with a qualified tax professional before relying on “tax-free reimbursement” language.
Corporation vs personal — and a sole-shareholder caution
Corporation path: Eligible expenses reimbursed under a qualifying plan for eligible employees. Design, eligibility classes, allocations, and administration matter.
Personal path: You pay personally and may explore personal medical expense tax credit rules. Different thresholds — not the focus here.
Sole employee-shareholder caution (light): CRA commentary has raised concerns that a self-insured HSA for a sole employee-shareholder and family may not qualify as a PHSP where there is little insurance risk. One-person or tightly held corps should get file-specific advice — this page does not decide your file. Also see self-employed health insurance in Alberta.
When you still want insured benefits (or both)
A cost-plus HSA is a flexible dollar tool, not a replacement for every insured benefit. Many owners still insure core risks and use the HSA for eligible gaps. Wellness / lifestyle dollars are a different (often taxable) bucket — see HSA vs WSA. For group-eligibility basics, see minimum employees for group benefits in Alberta.
Common mistakes to avoid
- US HSA confusion. Canadian HSA/HCSA products are not U.S. Health Savings Accounts.
- Assuming “no premiums” means “no cost.” You still fund claims and administration.
- Ad-hoc reimbursements without a plan. Random corporate medical reimbursements without proper design can create taxable-benefit problems — confirm with your accountant.
- Assuming every HSA is automatically a PHSP. Design, risk, eligible expenses, and administration matter.
- Ignoring sole-shareholder edge cases. One-person corporations need file-specific review.
- Mixing wellness into “medical write-off” language. Gym/lifestyle perks are typically WSA territory and commonly / typically taxable — see HSA vs WSA.
- Inventing tax savings percentages. Use your census and a quote or audit — not made-up Alberta averages.
Checklist before you rely on a corporate medical write-off story
- Confirm incorporation and who will be eligible under the plan.
- Choose the design: HSA alone, insured benefits alone, or hybrid — see HSA with group benefits.
- Separate medical vs wellness dollars (HSA vs WSA).
- Ask your accountant about PHSP framing, shareholder-employee facts, and payroll reporting before announcing “tax-free medical write-offs.”
- Define eligible expenses under your booklet — start with HSA / HCSA eligible expenses.
- Budget for claims + admin, not just a “no monthly premiums” line.
- Decide administration (claims proof, turnaround, portal).
- Bring census and goals to a multi-carrier conversation if you also want insured benefits or a second opinion.
FAQ
Can my Canadian corporation write off medical expenses with an HSA / PHSP?
Often, incorporated employers use a cost-plus HSA / HCSA discussed alongside PHSP concepts so the corporation reimburses eligible medical expenses under plan rules. When the arrangement qualifies as a PHSP, employer-funded reimbursements are often framed as non-taxable to eligible employees — confirm with a qualified tax professional. This page does not determine status for your file.
What does “cost-plus” or “no monthly premiums” mean?
Typically, the corporation pays eligible claims as they are reimbursed, plus administration fees, instead of paying monthly insurance premiums for that dollar pool. It is not free coverage, and it is not automatically a substitute for every insured benefit.
Is a Canadian HSA the same as a US HSA?
No. A Canadian Health Spending Account / HCSA is a different product concept from a U.S. Health Savings Account. Use Canadian plan materials and CRA guidance.
Can a one-person corporation use a cost-plus HSA?
Possibly in some designs — but CRA commentary has raised concerns about self-insured HSAs for sole employee-shareholders where there is little insurance risk. Get file-specific tax advice before relying on PHSP treatment. Also see self-employed health insurance in Alberta.
What expenses can be reimbursed?
Usually eligible medical, dental, vision, prescriptions, and related costs under the plan booklet and CRA medical-expense concepts — see HSA / HCSA eligible expenses. Your booklet controls; wellness/lifestyle items often belong in a separate WSA conversation (HSA vs WSA).
