HSA Rules for Self-Employed Canadians

If you are self-employed and paying for a GLP-1 prescription out of pocket, a health spending account looks like an obvious answer: run the cost through the business, deduct it, stop paying for it with after-tax dollars. Some of that works. Some of it does not, and CRA has published a warning about the version that does not.

This page describes what CRA publishes. It is about tax mechanics, not about medication.

Not tax advice. This is the highest-stakes page in this series and your situation decides the answer. Confirm everything here with the Canada Revenue Agency or your own accountant before you set up or pay into any arrangement. Nothing on this page is a recommendation to enter one.

The definition that governs everything

An HSA only delivers its tax advantage if the arrangement is a private health services plan (PHSP). When it is, CRA's payroll guidance is that "medical expenses paid under the terms of a private health services plan (PHSP) will not be taxable" to the employee (CRA, Medical expenses, including payments from a private health services plan (PHSP), accessed 30 September 2026). CRA's archived interpretation bulletin IT-339R2 sets out what qualifies as one (accessed 30 September 2026).

If the arrangement is not a PHSP, the tax result is not "slightly worse". The deduction goes away and the reimbursement is not sheltered.

CRA's buyer-beware warning, in CRA's words

This is the part worth reading twice. In a published tax tip, Warning: Buyer beware when it comes to Health Spending Accounts (18 April 2019), CRA states that "if the business is a sole proprietorship with no arm's-length employees, the CRA does not consider an HSA to be a private health services plan", and that in that case "any costs incurred for amounts paid to this account are not deductible business expenses" (CRA tax tip, accessed 30 September 2026). CRA's stated reason for publishing it was that these arrangements were being marketed to exactly those businesses.

Read plainly: a one-person business with no employees at arm's length cannot solve its prescription costs by paying into an HSA and deducting it.

Incorporated and unincorporated are not the same question

• Sole proprietorship, no arm's-length employees. CRA's position above applies directly.
• A business with arm's-length employees. An HSA can be part of a genuine employee benefit plan. Whether the arrangement qualifies as a PHSP turns on the plan's terms, not on the label the provider puts on it.
• Incorporated, owner is an employee of the corporation. Different analysis again, and one an accountant should do on your facts rather than one an article should assert. The questions that matter are whether there is a real employment relationship, whether the benefit is provided in that capacity, and whether the plan meets the PHSP definition.

Nobody can settle this from the outside. The useful step is to take the plan documents to your accountant before signing, and to ask the provider in writing why they say the arrangement is a PHSP.

The premium deduction that does exist for the self-employed

Separately from an HSA, CRA does allow self-employed individuals to deduct PHSP premiums against business income, subject to conditions. CRA's page on other business expenses states that you must be "actively engaged in your business on a regular and continuous basis, individually or as a member of a partnership", that "the premiums are paid to insure yourself, your spouse or common-law partner, or any member of your household", and that in the current or previous tax year either your net self-employment income is more than 50% of your total income or your income from other sources is $10,000 or less. The contract has to be with an insurance company, trust company, PHSP administrator or a tax-exempt trade union or professional organisation, and the deduction is reported on line 9270 of Form T2125 (CRA, Other business expenses, accessed 30 September 2026).

Three cautions. First, this is a deduction for premiums paid for coverage, not for the drug bill itself. Second, CRA's page sets out the conditions above but does not publish the dollar limits that can apply to this deduction — so confirm the amount you can actually claim with CRA or your accountant rather than assuming the full premium is deductible. Third, you cannot use the same premium twice: CRA states on the same page that "you cannot claim a deduction for PHSP premiums if another person deducted the amount, or if you or anyone else claimed the premiums as a medical expense".

What this means for a prescription bill

If the business route does not work for you — and for a one-person business with no employees, CRA says the HSA route does not — the remaining levers are the ones available to everyone:

• The medical expense tax credit. It does not require a plan, an employer or a business. A drug that lawfully requires a prescription and whose purchase is recorded by a pharmacist qualifies under the conditions CRA sets out in Income Tax Folio S1-F1-C1 ¶1.123 (accessed 30 September 2026), and only the amount above a floor produces a credit. The mechanics are in our page on GLP-1 prescriptions and the medical expense tax credit.
• Premiums you pay yourself. RC4065 lists "premiums paid to private health services plans including medical, dental, and hospitalization plans" as eligible medical expenses, claimable "as long as 90% or more of the premiums paid under the plan are for eligible medical expenses" (CRA, RC4065 Medical Expenses, accessed 30 September 2026). That can add to the same claim.
• Price. The one lever with no eligibility test at all. The same strength and quantity can differ substantially between Canadian pharmacies — compare on Ozempic, Wegovy, Mounjaro, Zepbound and Apo-Semaglutide, read how we verify prices, and see the generic Ozempic cost guide.

FAQ

Can a self-employed Canadian use a health spending account?

Only where the arrangement genuinely qualifies as a private health services plan. CRA's published position is that a sole proprietorship with no arm's-length employees does not have one, and amounts paid into such an account are not deductible business expenses.

Is an HSA deductible for a sole proprietor?

Not where there are no arm's-length employees — CRA says those costs "are not deductible business expenses". With arm's-length employees, it depends on the plan's terms; ask your accountant.

What about the premiums on private coverage I buy myself?

CRA allows a self-employed PHSP premium deduction on line 9270 of Form T2125 if you meet the conditions on its Other business expenses page. Limits can apply — confirm the deductible amount with CRA or your accountant.

Can I claim the prescription itself as a business expense?

A personal prescription cost is not a business expense. The route for it is the medical expense tax credit, or reimbursement from a plan that qualifies.

A provider told me their HSA works for my one-person business. Now what?

Read CRA's tax tip, then ask the provider in writing to explain why their arrangement is a PHSP, and have your accountant review the plan documents before you pay anything into it.

Which is better for me, the tax credit or a plan?

That is a question about your income, your expenses and your business structure, which is exactly the question to put to an accountant.
