Health Spending Accounts (HSA / PHSP) for Small Business Owners

If you own an incorporated business, a Health Spending Account converts personal medical expenses into fully-deductible corporate expenses. On $6,000 of annual health spending for a typical family, the savings run $2,000–$3,000 per year — every year, for the rest of your working life. Here is exactly how HSAs work, who qualifies, and the narrow but critical traps that can disqualify your deduction.

Meet the family this article is about

Jenn runs a consulting corporation in Calgary. She and her partner spent about $6,800 last year on their family's out-of-pocket medical costs: $2,400 on their daughter's orthodontics, $1,100 on prescription drugs, $1,600 on dental, $800 on massage therapy, and $900 on Jenn's prescription glasses plus an eye exam. They paid every dollar from their personal after-tax income, at Jenn's 43% marginal rate. To cover $6,800 of personal spending, the corporation first had to pay Jenn a $11,900+ dividend. A Class-of-One HSA would have eliminated over $5,000 of that tax waste.

The Mechanics — Three Roles, One Transaction

An HSA (also called a Private Health Services Plan, or PHSP, in the Income Tax Act) is a reimbursement arrangement. Three parties are involved:

🏢

Your corporation

Pays into the HSA. This payment is a tax-deductible business expense under section 20.01 of the Income Tax Act.

🧾

Third-party administrator

Holds the funds, processes claims, and ensures expenses qualify under CRA rules. Typical admin fees: 5-10% of claims.

👤

You (the employee)

Submit medical receipts. Reimbursement arrives tax-free — not a taxable benefit, not on your T4.

Why this is so tax-efficient

The alternative is paying yourself a salary or dividend, paying personal tax, then paying medical bills with what is left. With an HSA, the corporation pays the medical bill directly — no personal tax ever applies. For a 43%-bracket owner, every $1,000 of medical spending paid through an HSA saves roughly $750 compared to paying from after-tax personal income.

Who Actually Qualifies

The CRA is strict about what qualifies as a PHSP. Two separate tests apply depending on your business structure.

✅ Incorporated business (easiest path)

If you have a corporation and receive T4 employment income from it, you can set up a "Class of One" HSA covering just yourself, your spouse, and your dependants. No arm's-length employees required.

• Corporate payment: fully deductible
• Your reimbursement: not a taxable benefit
• No cap on annual spending (within reason — CRA can challenge excessive plans)
• Common structure for doctors, dentists, consultants, IT professionals

⚠️ Sole proprietorship (stricter rules)

The CRA's position is that an HSA set up for a sole proprietor with no employees is NOT a PHSP and the costs are NOT deductible. To qualify:

• You must have at least one arm's-length employee (not your spouse working less than 20 hours/week)
• All arm's-length employees must also be covered by the HSA (no carving out just yourself)
• Alternative: self-employed premiums can be deducted on your personal return if your business income is 50%+ of your total income, up to $1,500/person + $750/dependent annually

What You Can Reimburse

Any expense that qualifies for the CRA Medical Expense Tax Credit (METC) is generally reimbursable through an HSA. The list is broader than most business owners realize:

Expense	Eligible?	Notes
Prescription drugs & insulin	✓ Yes	Only prescription items — most OTC medications don't qualify unless prescribed.
Dental: cleanings, fillings, crowns	✓ Yes	Cosmetic whitening is not eligible.
Vision: glasses, contacts, LASIK	✓ Yes	Readers sold over-the-counter don't qualify without a prescription.
Physiotherapy, chiropractic, massage	✓ Yes	Must be performed by a registered practitioner — receipts required.
Psychology & counselling	✓ Yes	Therapist must be licensed and regulated in your province.
Fertility treatments (IVF, IUI)	✓ Yes	Including some related medications. Surrogacy costs have their own narrow rules.
Orthodontics (braces, Invisalign)	✓ Yes	Fully covered under most plans; progress payments count as they're billed.
Hearing aids & batteries	✓ Yes	Both the device and ongoing battery costs qualify.
Cosmetic surgery (purely aesthetic)	✗ No	Unless medically necessary (reconstruction, correction).
Gym memberships & wellness apps	✗ No	Not eligible under CRA's medical expense rules.
Non-prescription vitamins	✗ No	Including supplements, unless prescribed for a specific condition.
Health insurance premiums	✓ Yes	Premiums paid to qualifying private health plans are eligible.

Full list is in CRA Income Tax Folio S1-F1-C1 (Medical Expense Tax Credit). When in doubt, your HSA administrator will confirm before reimbursing.

Three Traps That Disqualify Your HSA

⚠️ Self-insured plans without a third-party administrator

If you just reimburse yourself out of the corporate account with no admin, CRA can deem it a salary/benefit rather than a PHSP. Always use a qualifying third-party HSA provider.

⚠️ Excessive or unreasonable annual caps

A "Class of One" HSA with a $100,000 annual limit and no actual use plan will be challenged. CRA looks for reasonable commercial terms similar to a group plan.

⚠️ Covering family members who aren't eligible dependants

Adult children who don't live with you, extended family, boyfriends/girlfriends — none qualify. Only legal spouses/common-law partners and dependants as defined in the ITA.

The Bottom Line

For Jenn: a Class-of-One HSA with a reputable administrator costs $150-300 in annual setup and admin fees. On her family's $6,800 in recurring annual health spending, the HSA saves roughly $3,000-3,800 per year in combined corporate and personal tax. Over 15 years until retirement, that is $45,000-50,000 of wealth — on expenses she is already spending, simply routed through a different pocket. If you are incorporated and paying medical bills personally, you are almost certainly leaving money on the table.
