Why Do Health Spending Accounts Still Have Tax in Ontario?
Understanding RST, Premium Tax, and PHSP Rules for Employers
Many Canadian business owners are surprised to learn that Health Spending Accounts (HSAs) and group benefits plans can still include taxes in Ontario – specifically Retail Sales Tax (RST) and Premium Tax (PT).
This raises a common question:
If HSAs and group benefits qualify as a Private Health Services Plan (PHSP) and are tax-free to employees, why do employers still see taxes on their benefits invoices?
The answer lies in an important distinction within Ontario tax law.
A tax-free employee benefit does not mean the transaction used to deliver that benefit is tax-free.
Understanding this difference helps explain why Ontario HSA tax rules include provincial charges such as Retail Sales Tax (RST) and Insurance Premium Tax (PT).
The Difference Between the Benefit and the Transaction
Under rules set by the Canada Revenue Agency (CRA), a Private Health Services Plan (PHSP) provides significant tax advantages:
- Employees receive reimbursements tax-free
- Employers can fully deduct benefit costs as a business expense
However, while the benefit itself is tax-advantaged, the insurance or administrative services used to deliver that benefit may still be taxed at the provincial level.
In Ontario, two taxes apply to employer benefit plans:
- 8% Retail Sales Tax (RST)
- 2% Insurance Premium Tax (PT)
These taxes apply at the plan level, not the employee level.
Employees still receive their reimbursements tax-free.
Why Ontario Applies Retail Sales Tax (RST) to HSAs
The 8% Retail Sales Tax (RST) applies because Ontario treats many benefit arrangements as insurance or insurance-like transactions.
The tax is administered by the Ontario Ministry of Finance.
Under these rules, RST applies to:
- Insured group health and dental plans
- Health Spending Accounts structured as PHSPs
- Administrative services related to insurance-type benefit arrangements
This means:
- Employers pay the 8% RST
- The tax cannot be recovered like HST
- It becomes part of the total cost of providing employee benefits
Importantly, this tax does not affect employee taxation.
Understanding Ontario’s 2% Insurance Premium Tax
Ontario also applies a 2% Insurance Premium Tax on certain insurance products, including:
- Life insurance
- Accident insurance
- Sickness and health insurance

This tax is typically remitted by the insurer or administrator but ultimately appears in the total premium paid by the employer.
Like RST, this tax:
- Does not apply to employees
- Does not make benefits taxable
- Simply reflects provincial taxation of insurance activity
Are HSAs Still Tax-Free in Ontario?
Yes.
Despite the presence of RST and Premium Tax, Health Spending Accounts remain one of the most tax-efficient employee benefit structures available in Canada.
When structured properly as a PHSP, HSAs remain:
- 100% tax-free for employees
- Fully deductible for employers
- Flexible compared with traditional group insurance plans
Many Canadian small businesses now use modern HSA-based benefit models because they provide predictable costs without the volatility of traditional insurance.
For example, platforms like Kibono offer pay-per-claim benefits that allow businesses to provide tax-advantaged health benefits while avoiding many of the cost drivers of traditional group insurance.
The Bottom Line: Why Ontario HSAs Still Include Tax
Health Spending Accounts and group benefits remain extremely tax-efficient — but the province taxes the mechanism used to deliver them.
| What Is Taxed | Who Pays |
|---|---|
| Employee reimbursements | No tax |
| Employer benefit deduction | Fully deductible |
| HSA or benefits transaction | Subject to 8% RST |
| Insurance premiums | Subject to 2% Premium Tax |
The 8% RST and 2% premium tax are unavoidable provincial charges tied to insurance transactions — not a failure of PHSP status.
Understanding this distinction helps employers see why Ontario HSA tax rules can look confusing on invoices while still delivering powerful tax advantages.
