How A Health Spending Account Works

HSA - June 04, 2026

How A Health Spending Account Works
A HSA (Health Spending Account) is a tax-effective benefit funded by the employer and used by an employee to pay for medical, dental, and vision expenses that fall under the Canada Revenue Agency (CRA) definition of eligible medical expenses. Reimbursements are tax-free to the employee and fully deductible for the employer.


Claim Workflow

1. Employee incurs an eligible expense
Pays out of pocket for a medical, dental, or vision service from a licensed provider. Expense must quality under the Income Tax Act.
Examples: prescription glasses, orthodontics, physiotherapy, prescription drugs.

2. Employee submits the claim
Uploads the receipt through the HSA administrator’s online portal or mobile app, including provider details, date of service, and amount paid.
Most administrators support direct mobile photo uploads.

3. HSA administrator adjudicates the claim
Verifies CRA eligibility, confirms available HSA balance, and reviews supporting documents. The claim is approved, partially approved, or declined.
Typical turnaround two to five business days.

4. Employee is reimbursed tax-free
Approved claims are deposited directly into the employee’s bank account. A statement of benefits is issued and the HSA balance is updated.
Reimbursement is not reported as taxable income.

5. Employer is invoiced
The administrator bills the employer for the reimbursed claim plus an 8.5% administration fee and applicable provincial tax.
Pay-as-you-go: employer is only billed for claims actually paid.

6. Employer pays via their business account
The administrator processes a pre-authorized debit from the employer's business bank account to cover the reimbursed claim amount, administration fee, and applicable taxes. Payment is triggered automatically following invoice generation.
No manual transfers required: the withdrawal is initiated by the administrator on a per-claim basis.



Why the administration fee exists

The 8.5% fee covers claims adjudication, CRA compliance, banking, employee portal access, application of transaction logistics and reporting. Because the HSA operates on a pay-as-you-go basis, the administrator only earns this fee when claims are actually paid – there are no monthly premiums and no float held by the carrier.

Tax treatment for the employer

The full amount on the invoice- the claim, the administration fee, and the GST – is a deductible business expense. This makes the HSA significantly more tax-efficient than reimbursing the same expense as a taxable bonus or salary top-up.

An HSA turns an ordinary medical bill into a tax-efficient benefit for both employer and employee — with no monthly premiums and no carrier float.

Key Plan Principles


Pay-as-you-go funding

The employer is invoiced only when claims are paid. There is no monthly premium, no minimum funding requirement, and no carrier float. Costs scale directly with actual employee plan utilization.

Tax-free to the employee

Reimbursements paid through an HSA are not reported as taxable income on the employee’s T4. A $500 reimbursement equals $500 in the employee’s pocket – the equivalent gross salary increase to deliver the same after tax-benefit would be substantially higher.

Best used as a complement

An HSA is most effective when paired with a traditional group benefits plan, covering items the core plan does not (such as orthodontics, laser eye surgery, or amounts over the annual maximum) rather than acting as a standalone solution.

CRA-defined eligibility

Eligible expenses are governed by the Canada Revenue Agency’s medical expense list under the Income Tax Act. The administrator enforces this list at the adjudication stage, protecting the plan’s tax-favoured status
