Benji VisserIf you run a small business in Canada, you have probably heard of two ways to help your team with health expenses: group health insurance and a Health Spending Account (HSA).
They both help pay for medical costs. But they work very differently.
This article compares the two so you can figure out which one makes more sense for your business. We are only comparing them on what they have in common: paying for medical expenses like dental, prescriptions, glasses, physio, and massage.
Things like life insurance, disability insurance, and critical illness coverage are separate products. They are not part of this comparison. You can add those on top of either option if you need them.
How group health insurance works
With group health insurance, your business pays a monthly premium to an insurance company. In return, the insurer covers certain medical expenses for your team based on the policy.
That policy decides what is covered, how much is covered, and what is not. It usually includes things like limits per category, co-pays, deductibles, waiting periods, and exclusions.
For example, your plan might cover 80% of dental up to $1,500 per year, or $500 per year for massage. If the expense is not in the policy, it is not covered. If you hit the cap, you are done for the year.
You pay the premium every month whether anyone uses the plan or not.
How an HSA works
An HSA works differently. Your business sets an annual budget for each employee or family, and then reimburses eligible expenses as they come in.
There are no category limits, no co-pays, no deductibles, and no exclusions. As long as the expense is eligible under CRA rules, the HSA covers it.
The business only pays when there is an actual claim, plus a small admin fee. If nobody submits a claim, you do not pay anything.
When the HSA is set up properly, the reimbursement is tax-free for the employee and tax-deductible for the business.
The key differences
| HSA | Group Health Insurance | |
|---|---|---|
| How you pay | Pay claims as they happen, plus an admin fee | Monthly premiums whether anyone uses it or not |
| What is covered | Anything eligible under CRA rules | Only what the insurance policy includes |
| Category limits | None. One budget covers everything | Separate caps per category (dental, vision, massage, etc) |
| Deductibles and co-pays | None | Often built into the policy |
| Waiting periods | None | Common, especially for dental and paramedical |
| Pre-existing conditions | No underwriting | Waiting periods or exclusions are common |
| Unused money | No premiums paid, so nothing is wasted | Premiums are gone whether anyone claims or not |
| Tax treatment | Tax-deductible for the business, tax-free for the employee | Depends on the plan component and province |
Which one covers more?
This surprises a lot of people. An HSA usually covers more than group health insurance, not less.
That is because an HSA follows the CRA's list of eligible medical expenses, which is very broad. Group health insurance follows the insurer's policy, which is narrower.
For example, an insurance plan might not cover fertility treatments, orthodontics for adults, or certain types of therapy. An HSA can cover all of those, as long as they are on the CRA eligible list.
With insurance, you also run into category caps. You might get $500 for massage and $300 for vision per year. With an HSA, the full budget can go toward whatever your employee actually needs. If they need $800 of dental and nothing else, the full $800 comes from the same budget.
How the cost compares
This is usually the biggest reason small businesses pick one over the other.
With group health insurance, you pay a monthly premium. That premium can change at renewal based on claims history, the age of your team, your province, and the insurer. You pay it every month even if nobody makes a claim.
With an HSA, there is no premium. You set a budget and pay claims as they come in, plus an admin fee. If nobody claims, you pay nothing.
| Group Health Insurance | HSA | |
|---|---|---|
| Monthly payment | Recurring premium to an insurer | No premium. Pay claims as they happen |
| Budget control | Insurer sets the price | You set the budget |
| Predictability | Premium can change at renewal | Budget stays what you set it to |
| Unused value | Premiums are gone if nobody claims | No premiums, so nothing is wasted |
| Tax treatment | Depends on the benefit and jurisdiction | Tax-deductible for business, tax-free for employee |
For a small team with mostly normal medical expenses, an HSA is often significantly cheaper than group health insurance.
Downsides of an HSA
An HSA is a strong option, but it is not perfect.
The employee usually pays for the expense first and then gets reimbursed. That means cash flow matters for the employee. This is exactly why Frontier HSA reimburses within 24 hours. Most other HSA providers take 3 days or more.
Only CRA-eligible expenses count. The list is broad, but it is not unlimited.
A sole proprietor without arm's-length employees generally cannot use one. An HSA works best for incorporated businesses, or unincorporated businesses that have at least one arm's-length employee.
Quebec has separate rules. Do not assume the federal tax treatment works exactly the same there.
And the budget is only as big as what you set. If you cap it for the year, that is the limit unless you decide to add more.
HSA vs. the Medical Expense Tax Credit
If you are an incorporated business owner, there are two main ways to get tax help on medical expenses.
One is to have the corporation reimburse the expense through an HSA.
The other is to pay personally and claim the Medical Expense Tax Credit on your personal tax return.
The Medical Expense Tax Credit is a personal tax credit. You can only claim the portion of your medical expenses that exceeds the lesser of $2,834 or 3% of your net income. So if you earn $90,000, the first $2,700 of your medical expenses does not count at all. And the credit only gives you partial relief on what is left, at tax time.
For example, if you have $4,000 of medical expenses and $90,000 of net income, the first $2,700 does not count (3% of $90,000). That leaves $1,300 eligible for the credit. At the 15% federal rate, that is about $195 back at tax time. With an HSA, the corporation reimburses the full $4,000 tax-free.
You cannot claim the same expense twice. If it was reimbursed through the HSA, you cannot also claim it under the Medical Expense Tax Credit.
Can you use an HSA and group insurance together?
Yes. Some businesses use both.
A common setup is group health insurance for things like high-cost drug coverage, and an HSA for routine medical, dental, and paramedical expenses. If your insurance plan only covers 80% of something, the HSA can cover the remaining 20%.
This gives you broader coverage while keeping costs under control.
When group health insurance makes more sense
Group health insurance is usually the better fit if:
- someone on your team has very expensive recurring drug costs that would eat through an HSA budget quickly
- your employees expect a traditional benefits card and plan booklet
- you want the insurer to handle everything and you do not mind paying the premium for that
That said, the case for group insurance gets weaker the smaller your team is. Insurance premiums are higher per person at small scale, and the risk pooling benefit is minimal when you only have a few people. For most teams under 5-10 people, an HSA is almost always the better starting point.
When an HSA makes more sense
An HSA is usually the better fit if:
- you are a small incorporated business
- your team mostly has normal everyday medical expenses
- you want more control over your budget
- you do not want to pay monthly premiums for coverage people may not use
- you want broader coverage than what a typical insurance policy offers
- you want a simple, flexible option without dealing with an insurance company
Bottom line
For covering medical expenses, an HSA and group health insurance do the same basic job: they help your team pay for health costs.
The difference is how they do it.
Group health insurance charges you a monthly premium and decides what is covered through a policy with limits, exclusions, and co-pays.
An HSA lets you set your own budget, covers anything CRA-eligible, and only costs you money when someone actually has a claim.
For most small businesses in Canada with normal medical expenses, an HSA is the simpler, cheaper, and more flexible option.
If you want to see how it works, Frontier HSA takes about 10 minutes to set up, has no monthly fees, and reimburses claims within 24 hours.
FAQ
Is an HSA the same as health insurance?
No. An HSA reimburses eligible medical expenses from a budget you control. Health insurance is a policy with premiums, limits, and insurer rules. They cover similar expenses but work very differently.
Can a sole proprietor use an HSA?
Usually only if the business is incorporated, or if the unincorporated business has at least one arm's-length employee.
Are HSA reimbursements taxable?
Generally not federally, when the plan is set up as a valid PHSP. Quebec has separate rules.
Can you switch from group insurance to an HSA?
Yes. The HSA should be set up properly before claims start, and the timing should match your insurance renewal or cancellation.
What about life insurance and disability?
Those are separate products. They are not part of the HSA vs health insurance comparison. You can buy life insurance, disability insurance, or critical illness coverage on top of either an HSA or group health insurance.
