Accountant's Guide to HSAs

This guide is designed for licensed tax professionals — accountants, CPAs, and tax advisors — who advise incorporated clients on the use of Private Health Services Plans (PHSPs) as a tax-efficient employee benefit.

Frontier HSA is structured as a cost-plus PHSP under ITA s.248(1), administered at arm's length. The plan reimburses CRA-recognized medical expenses and is designed to comply with all applicable provisions of the Income Tax Act, including IT-339R2 and related CRA technical interpretations.

The division of responsibilities is clear: Frontier administers claims and ensures plan compliance, while tax professionals assess the suitability of the plan for their clients' specific circumstances.

PHSPs are one of the most tax-efficient ways for incorporated businesses to cover health expenses. Compared to paying out-of-pocket via dividends, the savings are substantial.

All PHSP reimbursements are 100% deductible to the corporation as a business expense. For the employee, benefits received under a PHSP are tax-free under subparagraph 6(1)(a)(i) of the ITA, which excludes private health services plan benefits from employment income.

A Private Health Services Plan is defined under ITA s.248(1) as a contract of insurance for hospital or medical expenses, or any plan established to cover such expenses, provided it meets certain structural requirements.

Frontier HSA operates as a cost-plus arrangement as described in IT-339R2. Under this structure, the employer reimburses actual medical expenses incurred by the employee, plus an administration fee. This is distinct from traditional insurance in that there are no premiums paid in advance — costs are incurred only when claims are submitted.

The plan reimburses only CRA-recognized medical expenses as defined under ITA s.118.2 and further outlined in CRA guide RC4065. This ensures all reimbursements qualify for the tax treatment described above.

Frontier administers claims, ensures plan compliance, and provides CRA-ready documentation. The tax professional assesses whether a PHSP is suitable for the client's specific tax situation and corporate structure.

For a cost-plus arrangement to qualify as a PHSP, it must satisfy the "nature of insurance" requirement per IT-339R2, paragraph 6. Frontier HSA incorporates five structural elements to meet this requirement:

The CRA presumes that benefits received by a shareholder are taxable under s.15(1) unless the taxpayer can demonstrate that the benefit was received in their capacity as an employee, not as a shareholder.

To ensure PHSP benefits are treated as tax-free employment benefits under subparagraph 6(1)(a)(i), the following requirements should be met:

• Written employment agreement — The shareholder-employee should have a formal employment contract with the corporation that includes health benefits as part of compensation.
• T4 employment income — While employment status is ultimately a question of fact, paying T4 salary or bonus significantly strengthens the position that PHSP benefits are received in an employment capacity. Dividend-only compensation makes it difficult to defend against s.15(1) shareholder benefit characterization.
• Participation consistent with employee class — The shareholder-employee's plan benefits should be consistent with those offered to other employees in the same class. If the shareholder-employee is the only employee, the plan terms should still be reasonable and documented.
• Corporate minutes — A board resolution or corporate minutes documenting the establishment of the PHSP as an employee benefit.

PHSP benefits must be offered on a non-discriminatory basis within employee classes. Classes must be based on legitimate employment criteria — not shareholding status.

Valid classification criteria include:

• Full-time vs. part-time status
• Length of service
• Job function or department
• Management vs. non-management

Key rules:

Eligible expenses are determined by ITA s.118.2 and CRA guide RC4065. Frontier reviews every claim against these criteria. For a complete list of covered expenses, see our eligible expenses page.

Enhanced Documentation Items

Certain expenses require additional documentation to confirm eligibility:

• Travel for medical care — Must be to obtain medical services not available locally. Requires documentation of distance and medical necessity.
• Supplements and vitamins — Must be prescribed by a medical practitioner and recorded by a pharmacist.
• Home modifications — Must be medically necessary and prescribed by a medical practitioner.

Ineligible Items

• Cosmetic procedures (unless medically necessary)
• Gym memberships and fitness equipment
• Over-the-counter products without a prescription
• Insurance premiums

PHSPs are available to incorporated businesses in all Canadian provinces and territories, but two provincial considerations affect plan administration:

Frontier HSA follows a structured claim process designed for compliance and efficiency:

1. Submission — The plan member submits a photo of the receipt via the Frontier app or web portal. Required documentation includes: provider name, date of service, description of service, amount paid, and patient name.
2. Review — Each claim is reviewed against ITA s.118.2 eligibility criteria. Frontier applies a conservative interpretation policy, meaning borderline claims are flagged for additional documentation rather than automatically approved.
3. Approval & Reimbursement — Approved claims are reimbursed via EFT same day. The corporation is invoiced for the claim amount plus the administration fee.
4. Documentation — All claims, receipts, and approval records are retained by Frontier for audit support.

Plan members must submit claims within 12 months after the end of the benefit year for eligible expenses incurred during that benefit year. This carry-forward/grace period aligns with CRA guidance in IT-529, paragraph 16, which permits a plan to carry forward either unused allocation or eligible expenses (but not both) for up to 12 months without disqualifying the arrangement as a PHSP.

Unused entitlement expires at the end of that period and cannot be cashed out or transferred (other than as a premium to another PHSP, if applicable). Because Frontier operates on a pay-as-you-go basis, the corporation is only invoiced when claims are submitted — there is no pre-funded pool. Each plan member is allocated an annual benefit entitlement, and any unused portion expires. The corporation never pays for unclaimed amounts, but the employee permanently loses the right to claim against them.

This expiry provision helps evidence the reasonable element of risk required for a plan to qualify as a PHSP under ITA s.248(1). CRA notes that where there is little risk an employee will not eventually be reimbursed for the full annual allocation, the arrangement may fail to meet the "nature of insurance" test described in IT-339R2, paragraph 3. Employees have no inherent right to the balance of credits in the account, and if an employee can withdraw or transfer amounts from the plan (except to pay a premium to another PHSP), the arrangement will not qualify as a PHSP and reimbursements become taxable employment benefits.

What Frontier Retains

Sole proprietors cannot participate in a PHSP. The definition under ITA s.248(1) requires an employer-employee relationship, which does not exist when an individual is self-employed.

A sole proprietor cannot be both the employer and the employee. The absence of this separation means the arrangement fails to meet the fundamental structural requirements of a PHSP.

Alternative for sole proprietors: Medical expenses may be claimed as a Medical Expense Tax Credit (METC) under ITA s.118.2 on the individual's personal tax return.
