Enhance employee benefits with a Health Spending Account

A Health Spending Account is one of the few employee benefits where the tax treatment is genuinely good on both sides. The employer deducts what it spends. The employee receives the reimbursement without paying tax on it. There is no premium to a third party insurer for coverage nobody uses.

It also gets skipped, usually because owners assume it is complicated or confuse it with the American account of the same name, which works nothing like this one.

What an HSA actually is

In Canadian tax terms an HSA is a private health services plan. The employer sets an annual amount for each employee. The employee pays for eligible medical or dental costs, submits the receipt, and the plan reimburses them from their allotted amount. Nothing is paid out until a claim is made.

Eligible expenses are broadly the ones that qualify for the medical expense tax credit, which is a much longer list than most group plans cover:

• Prescription medication
• Dental work, including major restorative work
• Vision care, glasses and laser correction
• Physiotherapy, chiropractic and massage from a qualifying practitioner
• Psychological and mental health services
• Orthotics, hearing aids and medical devices
• Deductibles and co-pays left over from a spouse's group plan

How the money moves

1. The employer sets the limits. Amounts can differ by class of employee, for example by role or years of service, provided the classes are reasonable. They can be reset each year.
2. The employee incurs an expense and claims it. Most businesses use a third party administrator who adjudicates claims against the CRA eligible list.
3. The plan reimburses the employee. No tax is withheld and the amount is not added to their income.
4. Unused amounts. CRA permits a carry forward of unused credits, or of unclaimed expenses, for a maximum of 12 months. Anything beyond that is lost.

Why it is tax efficient

The employer's cost is a deductible business expense, so it reduces taxable income the same as any other staff cost. Because the reimbursement is not employment income, no CPP or EI is payable on it, and it does not go through payroll.

Take a business setting aside $1,000 a year for each of five employees. The full $5,000, if it is all claimed, is deductible. Nothing is added to any employee's T4. There are no employer CPP or EI costs attached to it, which is not true of a $1,000 raise. What the employee receives is the full $1,000 of purchasing power, where a raise of the same size arrives after tax at their marginal rate.

The costs to weigh against that are the administrator's fee, which is normally a percentage of claims paid and carries GST/HST, and the fact that unclaimed money does not benefit anyone.

The rules that trip employers up

It has to be a plan, not a reimbursement habit. There needs to be a written plan document setting out who is covered, the annual amounts and what is claimable. Ad hoc reimbursement of an employee's dental bill is a taxable benefit.

Employees cannot choose cash instead. If the arrangement lets someone take the money as pay rather than as a health reimbursement, it stops being a private health services plan and the whole amount becomes taxable.

Coverage classes have to be defensible. A plan that covers the owner generously and everyone else minimally invites the argument that the owner received the benefit as a shareholder rather than as an employee, which makes it taxable to them and non-deductible to the corporation.

Unincorporated businesses face caps. A sole proprietor or partner can deduct payments for themselves and their household, but the annual amount per person is limited by statute and there are conditions where the business has arm's length employees. Confirm the current caps before budgeting.

Owner-only corporations need care. A corporation whose only employee is its shareholder can have a valid plan, but the coverage has to be reasonable in relation to the employment. This is worth structuring properly at the outset rather than defending later.

Where it fits in a benefits package

An HSA works well as the whole benefit for a small team, or alongside a basic group plan where it picks up the deductibles and the categories the insurer excludes. It is common in professional services, trades and health and wellness practices, where staff costs are the main expense and a traditional group plan is priced for a larger headcount. We see it used often in the clinics we work with.

Setting one up means choosing an administrator, writing the plan document, and recording the reimbursements correctly in the books so the deduction is clean at year end. That bookkeeping and payroll side is covered in bookkeeping, HST and payroll. An HSA also sits alongside several other benefits that are deductible to the business and tax-free to the employee, which we set out in smart employee benefits.
