Reviewed July 1, 2026 · Health and dental plans for Canadians outside Quebec.
A Health Spending Account can turn medical and dental costs you were already paying into a legitimate business expense. It is one of the quiet advantages of working for yourself — but the rules are very different for a sole proprietor than for an incorporated owner, and an HSA is not a substitute for insurance. Here is how they actually work.
Is this you?
- You are self-employed and paying for drugs, dental, or glasses out of your own pocket.
- You have heard an HSA is a tax-smart way to cover health costs and want to know if it fits.
- You are trying to decide between a health spending account, an insured plan, or both.
If any of those fit, read on.
What a Health Spending Account is
A Health Spending Account (HSA) is a form of private health services plan. Rather than paying a fixed insurance premium, your business funds an account, and eligible medical and dental expenses are reimbursed from it — generally as a deductible expense to the business and a tax-free benefit to the person receiving it.
The key distinction: an HSA is a spending arrangement, not insurance. It does not pool risk across many people. If you spend more than the account holds, the account does not bail you out. That is exactly why it pairs well with, rather than replaces, an insured plan.
The rules for sole proprietors — mind the cap
If you are a sole proprietor with no arm's-length employees, the Canada Revenue Agency caps how much you can deduct through a private health services plan each year. The annual limits are:
- $1,500 for the proprietor.
- $1,500 for a spouse or common-law partner.
- $1,500 for each dependant 18 or older.
- $750 for each dependant under 18.
To use this route at all, you generally must be actively engaged in the business on a regular and continuous basis and meet an income test — broadly, your self-employment income has to be your main income, or your other income has to be modest. These are CRA figures and conditions; confirm the current ones on Canada.ca before relying on them.
Why incorporation changes the math
An incorporated business with legitimate employees generally is not bound by those sole-proprietor caps. A properly structured HSA can then reimburse a broader range of eligible costs as a business expense. But there are conditions: it must be a genuine private health services plan, the benefits must be reasonable, and the arrangement usually runs through a third-party administrator rather than paying yourself directly. This is firmly accountant territory — set it up on advice, not assumptions.
HSA vs. an insured plan — use the right tool
They are not competitors so much as complements:
- An HSA shines for predictable, everyday costs — routine dental, a new pair of glasses, a recurring prescription. You are essentially pre-funding known expenses with pre-tax dollars.
- An insured health and dental plan shines for big, unpredictable costs — an expensive specialty drug, a crown, a hospital extra. Because it pools risk, a $50 monthly premium can stand behind thousands in coverage.
The common self-employed setup is both: an insured plan for the catastrophic and unknown, an HSA for the routine and predictable.
The one rule not to break
You cannot run a cost through your HSA as a business deduction and claim that same cost personally on the Medical Expense Tax Credit. That is double-dipping, and the expense has already had its tax benefit. Keep clean records of what the HSA reimbursed versus what you paid out of pocket, so the two never overlap.
The bottom line
A Health Spending Account is a real advantage for the self-employed, but it rewards people who understand its limits: capped for sole proprietors, powerful but structured for incorporated owners, and never a replacement for the risk protection an insured plan provides. Decide which costs are predictable and which are catastrophic, and cover each with the right tool.
If the insured half of that picture is what you are missing, see what real plans cost for your age and province and compare plans side by side. It takes about two minutes.

Frequently asked questions
What is a Health Spending Account?
A Health Spending Account (HSA) is a type of private health services plan that lets a business pay for employees' — or an owner's — eligible medical and dental costs and treat them as a business expense. Instead of paying a fixed insurance premium, the business funds an account, and eligible expenses are reimbursed from it, typically tax-free to the person receiving the benefit. It is a spending arrangement, not an insurance policy, so it does not pool risk the way a plan does.
Can a sole proprietor use a Health Spending Account?
Yes, but with a hard cap. Where a business has no arm's-length employees, the Canada Revenue Agency limits the annual amount a self-employed person can deduct through a private health services plan to roughly $1,500 for the proprietor, $1,500 for a spouse, $1,500 for each dependant 18 or older, and $750 for each dependant under 18. You also have to be actively engaged in the business and meet an income test. These figures and rules are set by CRA — confirm the current ones on Canada.ca.
How is an HSA different for an incorporated business?
An incorporated business with legitimate employees generally is not bound by the sole-proprietor annual caps, so a properly structured HSA can reimburse a wider range of eligible costs as a business expense. But the plan still has to be a genuine private health services plan, benefits must be reasonable, and the arrangement usually needs a third-party administrator. The details matter, so incorporated owners should set one up with an accountant rather than on assumptions.
Is a Health Spending Account better than a health and dental plan?
They solve different problems. An HSA is efficient for predictable, everyday costs you know you will spend — routine dental, glasses, recurring prescriptions — because you are essentially pre-funding them with pre-tax dollars. An insured health and dental plan protects against big, unpredictable costs, like a major drug or a large dental bill, because it pools risk. Many self-employed people use both: an insured plan for the catastrophic, an HSA for the routine.
Can I claim the same expense on an HSA and the Medical Expense Tax Credit?
No — you cannot deduct a cost as a business expense through an HSA and also claim it personally on the Medical Expense Tax Credit. That would be double-dipping. An expense reimbursed by your HSA has already received a tax benefit, so it is not also eligible for the personal credit. Keep clean records of what went through the HSA versus what you paid out of pocket, and confirm the treatment with a tax professional.
