Benji VisserIf you run an unincorporated business in Canada, you have probably heard that sole proprietors cannot get a Health Spending Account. That is only half the story. A sole proprietor without arm's-length employees cannot set up a self-insured HSA. But if you have at least one arm's-length employee, the door opens for them and for you.
This guide covers who qualifies, what the CRA actually requires, how the contribution caps work, and when incorporating is the better path.
Frontier HSA does not currently offer plans for sole proprietors. The CRA rules for sole proprietor HSAs are complex and easy to get wrong. We only administer plans for incorporated businesses to make sure every plan is on solid ground. If you are considering incorporating, see our guide for incorporated professionals.
The short answer
It depends on whether you have arm's-length employees.
Sole proprietor with no employees: You cannot set up a self-insured HSA for yourself. The CRA does not accept this arrangement because there is no legal separation between you and the business.
Sole proprietor with arm's-length employees: You can set up an HSA that covers your employees. You may also be able to claim your own self-employed PHSP premium deduction if you meet additional income tests.
Incorporated business owner: You may qualify as a shareholder-employee even if the corporation has no other employees. Incorporation alone is not enough: you must actively work in the corporation's day-to-day operations and receive the HSA because of that employment, not simply because you own shares.
Why the CRA treats sole proprietors differently
A Health Spending Account must qualify as a Private Health Services Plan (PHSP) under the Income Tax Act. The CRA's position is that a PHSP must function like real insurance, with an undertaking to indemnify another person for a loss or liability where the event is uncertain.
For an incorporated business, the corporation is a separate legal entity from the owner. That makes it possible for the owner to be an employee or officer of the corporation, but incorporation alone does not prove an employment relationship. The facts must support active work and an employment-based benefit.
For a sole proprietorship, there is no such separation. You are the business. You cannot insure yourself against your own expenses and call it a benefit. The CRA sees this as a personal expense, not an employee benefit.
The exception is when you have arm's-length employees. Once you employ someone who is not related to you, the plan starts to look like a genuine employee benefit rather than a personal reimbursement vehicle.
What "arm's-length" means
An arm's-length employee is generally someone who is not related to you and is not carrying on the business with you as a partner. Your spouse, your children, your siblings, and your parents usually would not count.
If your only help is your spouse doing the bookkeeping, that will not qualify you. Hiring even one part-time employee who is not related to you may be enough, but the employee relationship has to be real.
If you don't have arm's-length employees and don't plan to hire any, incorporating may make an HSA possible. As an incorporated shareholder-employee, you do not need arm's-length employees, but you still need an active employment or officer role. See our guide for incorporated professionals for more details.
How the contribution caps work
Even if you qualify, your contribution limits as a sole proprietor are more restricted than those of an incorporated business.
If 50% or more of your employees are arm's-length: Your maximum deduction is based on the lowest cost of equivalent coverage for each qualified employee. In practice, this means you cannot give yourself more generous coverage than you give your employees.
If fewer than 50% of your employees are arm's-length: Your maximum deduction is the lesser of:
- The lowest cost of equivalent coverage for each qualified employee
- The annual dollar-limit formula: $1,500 per insured adult and $750 per insured child under 18
For a family of four, that means a maximum of $4,500 per year. Compare this to an incorporated business, where there is no fixed dollar cap.
If you have an arm's-length employee with no coverage: You cannot claim your PHSP premiums as a deduction from self-employment income. You may still be able to claim them as medical expenses on your personal tax return.
The income test
Before you can deduct your own PHSP premiums, you must meet one of these tests:
- 50% income test: At least 50% of your total personal income comes from your sole proprietorship (in the current or previous year)
- $10,000 test: Your total income from all other sources (investments, rental income, other employment) is less than $10,000
You must also be actively engaged in the business on a regular and continuous basis.
How to set up an HSA as a sole proprietor
If you meet the arm's-length requirement and the income test, here are the steps:
- Verify your arm's-length employees. At least one person on your payroll must have no family relationship to you. The employment relationship must be genuine.
- Choose a benefit amount. Your limit cannot exceed what you offer to your qualified employees. If fewer than 50% of employees are arm's-length, the $1,500/$750 cap applies.
- Keep the rules separate. Reimbursements under a valid PHSP are generally non-taxable to employees. Your own claim is subject to the separate self-employed PHSP deduction rules.
- Sign up with a CRA-compliant provider. The provider should handle plan documentation, claims processing, and reporting to keep you aligned with CRA rules.
The alternative: incorporate
If the contribution caps feel too tight or the arm's-length requirement does not apply to your situation, incorporating your business removes most of these restrictions.
An incorporated owner may qualify as a shareholder-employee without arm's-length employees and without the sole-proprietor $1,500/$750 formula. T4 salary or bonus is Frontier's preferred evidence of the employment relationship. A dividend-only shareholder-employee is not automatically disqualified, but Frontier requires other supporting documentation and confirmation from the corporation's accountant. A passive or non-working shareholder does not qualify simply because the corporation is a separate taxpayer.
Incorporation has costs (legal fees, annual filings, accounting complexity), but if you are spending more than a few thousand dollars a year on medical expenses, the HSA tax savings often outweigh those costs.

A warning about fraudulent providers
The CRA has issued a public warning about providers that falsely claim sole proprietors without employees are eligible for HSA plans. These arrangements can result in unexpected tax liabilities, penalties, and interest. If a provider tells you that you can get an HSA as a sole proprietor with no employees, that should be a red flag.
Sole proprietor HSA vs. incorporated HSA
| Sole proprietor HSA | Incorporated HSA | |
|---|---|---|
| Employees required | At least one arm's-length employee | None |
| Owner eligible | Only with arm's-length employees and income test | May qualify as a shareholder-employee |
| Annual cap (owner) | $1,500/adult, $750/child (if <50% arm's-length employees) | No fixed cap |
| Equal benefit rule | Coverage tied to what employees receive | No requirement |
| Tax treatment for employees | Reimbursements are non-taxable | Reimbursements are non-taxable |
| Tax treatment for owner | Self-employed PHSP deduction (separate rules) | Same as employee |
| Setup complexity | Higher | Lower |
If you do not qualify: the METC
If you are a sole proprietor without employees and are not ready to incorporate, the Medical Expense Tax Credit (METC) on your personal tax return is your main option for tax relief on medical expenses.
The METC is a non-refundable credit that kicks in once your total eligible medical expenses exceed 3% of your net income (or a fixed threshold set by the CRA, whichever is lower). It does not eliminate the tax on your medical expenses entirely, but it reduces what you owe.
For a detailed comparison, see our guide on METC vs. HSA.
Frequently asked questions
Can I set up an HSA if I am a sole proprietor with no employees?
No. The CRA does not accept a self-insured HSA for a sole proprietorship with no arm's-length employees. You may be able to deduct PHSP premiums under the separate self-employed PHSP rules, but this is not the same as a traditional HSA reimbursement account.
Does my spouse count as an arm's-length employee?
Generally, no. The CRA considers your spouse, children, siblings, and parents to be non-arm's-length. You need at least one employee who is not related to you.
Can I give myself more coverage than my employees?
No. Your maximum deduction is tied to the lowest cost of equivalent coverage for each qualified employee. And if fewer than 50% of your employees are arm's-length, you are also subject to the $1,500/$750 annual cap.
What if I only have one part-time employee?
One part-time arm's-length employee can be enough to qualify, as long as the employment relationship is genuine. But your own contribution cap will be tied to what you provide that employee.
Should I incorporate instead?
If you do not have arm's-length employees and want an HSA, incorporating may be the better path. It removes the sole-proprietor arm's-length requirement and the $1,500/$750 formula, but it does not make a passive shareholder eligible. The owner must still qualify as a shareholder-employee. The decision involves other factors, including legal fees, annual filings, and accounting, so get professional advice before incorporating.
Does Frontier HSA offer plans for sole proprietors?
Frontier HSA only offers plans to incorporated employers, including qualifying shareholder-employees and businesses with staff. The sole proprietor rules are narrower and easier to get wrong, and we want to make sure every plan we administer is on solid ground with the CRA.
