Benji VisserA Canadian small business can use a Health Spending Account to reimburse eligible medical expenses through a Private Health Services Plan (PHSP). When the arrangement qualifies, reimbursements are generally not taxable to employees and are deductible to the business. There are no premiums, no insurance company, and no pre-set coverage tiers. The business pays only when claims are submitted.
This guide covers how to set one up, what it costs, who it covers, and how to keep it CRA-compliant.
The short answer
An incorporated small business can set up an HSA for its employees, including the owner if they are on payroll. There is no minimum number of employees. The business chooses a benefit limit, employees submit receipts for CRA-eligible medical expenses, and the business reimburses them. That reimbursement is a deductible business expense, and the employee receives it tax-free.
Why small businesses use HSAs instead of insurance
Traditional group insurance and an HSA solve different problems.
| Factor | Traditional group insurance | HSA / PHSP reimbursement |
|---|---|---|
| Cost model | Premiums are paid whether or not anyone claims | The business reimburses eligible claims and may pay an admin fee |
| Coverage | Set by the insurer and plan design | Set by the plan terms and CRA eligibility rules |
| Claim review | Insurer adjudicates the claim | Provider or administrator reviews receipts and plan rules |
| Tax treatment | Depends on the plan | Generally not taxable to the employee if the plan qualifies as a PHSP |
| Unused budget | Premiums are gone whether used or not | Unused balances can roll forward depending on plan terms |
| Flexibility | Fixed categories and caps | Any CRA-eligible expense, no per-category limits |
For small teams, the reimbursement model is often simpler and cheaper. There are no renewal increases, no bundled packages, and no coverage that disappears at the end of each year.
An HSA can cover eligible medical expenses the CRA recognizes under RC4065, including dental, vision, prescriptions, physiotherapy, massage therapy, chiropractic, mental health, fertility treatments, and medical devices. Eligibility depends on the specific expense, the supporting documents, and any practitioner or prescription requirements that apply.
How much does an HSA cost?
An HSA has two cost components:
- The eligible reimbursements you pay out under the plan
- The provider or administrator fee
The reimbursement itself is the main cost, and it only happens when employees actually submit claims. Provider fees vary. Frontier HSA charges 8% per approved claim with no setup fee, no annual fee, and no monthly minimums.
A simple example
An incorporated business owner spends $5,000 in a year on eligible medical expenses: dental work, glasses, prescriptions, and physiotherapy.
- Paying personally: The $5,000 comes from after-tax personal income. At a 40% marginal rate, the owner needs to earn roughly $8,300 pre-tax to have $5,000 after tax.
- Paying through an HSA: The corporation reimburses $5,000 plus an 8% admin fee ($400), for a total corporate outlay of $5,400. That $5,400 is a deductible business expense, and the owner receives the $5,000 tax-free.
The exact savings depend on the province, income level, and corporate structure, but the HSA route is almost always more tax-efficient than paying out of pocket.
Choosing a benefit limit
The CRA does not publish a universal dollar cap for HSAs. What matters is whether the arrangement qualifies as a PHSP.
For a self-insured HSA-style plan, the CRA says that all or substantially all (generally 90% or more) of the amounts paid under the plan must be for eligible medical expenses. As long as that test is met, you have flexibility in setting the limit.
Different employee classes can have different limits (executives vs. full-time staff vs. part-time staff), but the classes need to be real and supportable. Document the reason for any differences and make sure the plan still fits the PHSP rules.
How do you set up an HSA?
Setting up an HSA involves three things:
- Decide who the plan covers. Employees, owner-managers on payroll, or a defined class of employees.
- Write down the plan rules. Who can claim, what expenses are eligible, how claims are submitted, and whether unused amounts roll forward.
- Use a reimbursement process that matches CRA rules. The tax result depends on the actual plan, not just the label.
With Frontier HSA, the workflow is:
- Create your business account. Enter your business and contact details.
- Set your plan limits. Choose an annual or monthly ceiling for each covered person or class.
- Add covered employees. Invite them to submit claims through the platform.
- Start reimbursing claims. Once the plan is live and the documents are in place.
The setup is designed to be quick and mostly paperless.
Does an HSA cover spouse and dependants?
Yes, depending on the plan wording.
For CRA medical expense purposes, eligible expenses can be claimed for the employee, a spouse or common-law partner, children under 18, and certain other dependants who meet the support and residence tests.
Who may be covered
- Spouse or common-law partner if the plan covers them and the expense is eligible
- Children under 18 covered in the main family bucket for medical expense purposes
- Other dependants if they are dependent on the employee for support and meet the CRA residence rules
Family coverage example
Mark runs a small incorporated business and sets up an HSA with a $3,000 annual limit. His family uses it for:
| Expense | Amount |
|---|---|
| Kids' dental cleanings and a filling | $900 |
| New glasses for spouse | $500 |
| Physiotherapy for Mark's back | $600 |
| Prescriptions for the family | $500 |
| Orthodontic consultation | $500 |
| Total | $3,000 |
The corporation reimburses these eligible expenses, deducts them as a business expense, and the family receives the benefit tax-free.
How does the claims process work?
- Pay for an eligible medical expense. Dental, vision, prescriptions, therapy, or another eligible item.
- Submit the receipt. Photo or upload through the provider's app or portal.
- Receive reimbursement. By EFT, usually within 24 hours with Frontier HSA.
When the plan qualifies, the reimbursement is not taxable to the employee. The business deducts the reimbursement as a business expense.
What documents do employees need?
| Required document | Notes |
|---|---|
| Itemized receipt | Keep the provider name, date, description, and amount |
| Proof of payment | Card record, bank record, or payment confirmation |
| Prescription or certification | Required for some drugs, devices, and expense categories |
| Practitioner details | Needed for certain province-specific practitioner claims |
Claim requirements by category
- Massage therapy and chiropractic: Check the CRA's province-specific authorized practitioner list. Some provinces recognize certain practitioners and others do not.
- Prescription drugs and medical devices: Many items need a prescription or must meet a specific CRA rule. Over-the-counter products do not qualify just because a practitioner recommends them.
- Fertility treatments: Many fertility-related expenses qualify, including IVF-related costs, but the exact expense matters.
- Laser eye surgery: Generally an eligible medical expense. Keep the invoice and supporting documentation.
- Vision care: Prescription eyewear is commonly eligible. Keep the receipt and any prescription.
- Cosmetic procedures: Purely cosmetic procedures (liposuction, wrinkle filler, teeth whitening) are generally not eligible. Reconstructive or medically necessary procedures may qualify.

Does an HSA work for remote and distributed teams?
Yes. A reimbursement plan can be used across Canada without a provider network. Employees submit claims from different provinces, and the business reimburses eligible expenses from one plan.
Why an HSA is simpler for remote teams
- No provider network. Employees choose their own doctors, dentists, therapists, and pharmacies.
- One reimbursement workflow. Same claim process regardless of where the employee lives.
- Portable administration. Employees upload receipts from anywhere.
- Simpler onboarding. No insurer enrollment process.
If someone moves provinces, the reimbursement workflow stays the same. Some CRA rules for specific expense types can change based on the practitioner and province, but the plan itself is national.
How does an HSA help with hiring and retention?
Offering a health benefit helps a small business compete with larger employers.
- It covers real spending. Employees use the benefit for expenses they actually have.
- It is flexible. Different employees use the budget for different needs.
- It is tax-efficient. Reimbursements are not taxable to the employee.
- It works for small teams. A reimbursement plan is simpler to explain than a traditional insurance package.
- It complements salary. A reimbursement of eligible medical expenses is more tax-efficient than a salary increase for the same amount.
Who qualifies for an HSA?

Frequently asked questions
How long does setup take?
Frontier's online workflow is designed to be quick. Most businesses can set up and start accepting claims within a day.
Do I need to pre-fund the account?
Not with a pay-as-you-go model like Frontier HSA. You reimburse claims as they are approved.
What if nobody submits claims in a given month?
The reimbursement cost is zero for that month. With Frontier HSA, there is no monthly minimum or administration fee when there are no claims.
Can I use an HSA alongside group insurance?
Yes. Many businesses use both. The HSA covers eligible out-of-pocket costs that insurance does not pay, as long as the claim is otherwise eligible under the plan.
Is there a contract or cancellation fee?
That depends on the provider. Frontier HSA has no contract and no cancellation fee.
Will my HSA hold up in a CRA audit?
It can, if the plan is properly structured, documented, and administered. Having a third-party administrator handle claims makes it much easier to stay on the CRA's good side.
Can sole proprietors use an HSA?
Sole proprietors have separate PHSP premium deduction rules. See our sole proprietor guide for the full details.
How is an HSA different from a Health Care Spending Account (HCSA)?
In the market, people use HSA, HCSA, and PHSP interchangeably. For tax purposes, the important question is whether the arrangement qualifies as a PHSP.
