A professional corporation outside Quebec can run an HSA with limits by role for principals, associates and staff. Frontier suits uneven claims at 8% of approved claims plus taxes, with no fixed fees; Coastal's 7% plus a $50 setup fee costs less above $5,000 of steady claims. A partnership or LLP covers employees, not partners. A group plan adds life and disability cover.

Why the firm's structure comes first
Law firms and accounting practices are organized in more ways than most small businesses, and the structure decides who an HSA can cover. A Health Spending Account is a Private Health Services Plan: an employer reimburses eligible medical expenses for its employees. So the first question is who the employer is and who its employees are. Three set-ups cover most small firms.
One professional corporation that employs everyone. The corporation sponsors the plan. Associates, students and support staff are employees. Principals who hold shares are covered as shareholder-employees if they actively work in the practice. This is the simplest case, and the one the rest of this post works through.
A partnership or LLP. Partners are generally not employees of the partnership, so a plan run by the firm covers the associates and staff the partnership pays, not the partners themselves. Where each partner practises through their own professional corporation, that corporation can run its own HSA for the partner as a shareholder-employee, subject to the employment test and the owner-only caveats below. Frontier serves incorporated businesses only, so the partnership cannot be the sponsor with us; the partners' corporations can. Our PHSP explainer has the table by business type.
A sole practitioner's professional corporation. One principal, maybe a part-time assistant. The corporation can run a plan, but a principal who is the only employee needs the owner-only review covered below.
Frontier serves incorporated businesses outside Quebec and does not enrol sole proprietors, partnerships or LLPs as the plan sponsor. Check your eligibility before planning around a provider.
The shareholder-employee test for principals
A principal qualifies as a shareholder-employee when they actively work in the practice's day-to-day operations and receive the benefit because of that work, not because they own shares. T4 salary or bonus is Frontier's preferred evidence. A principal paid only in dividends must provide other documentation of their role and have the corporate accountant confirm the arrangement before enrolling. Passive, retired or non-working shareholders, and holding companies with no active employees, do not qualify.
One more point for the sole practitioner. At the May 3, 2022 CALU roundtable (2022-0928901C6), the CRA said a self-insured HSA for a sole shareholder-employee and their family would likely fail the insurance requirement a Private Health Services Plan must meet. Our accountant guide sets out the reasoning, and our post for incorporated consultants works through the one-person case. The CRA's answer was about a plan covering only the sole shareholder-employee and family. Whatever the firm's structure, each principal's own employment still has to be real, and your accountant should review the plan.
Classes by role, and what the CRA allows
A benefit class is a group of employees who share the same limit. The CRA allows different classes to receive different amounts when the grouping rests on employment criteria, not personal characteristics. A firm usually defines its classes by role, such as principal, associate, student and support staff, and by full-time versus part-time. Everyone in a class gets the same limit, and the limit must be reasonable for the role and its pay.
Here is an illustrative plan for a nine-person professional corporation. Yours will differ, and your accountant should review it.
| Class | Who | Annual limit | Total |
|---|---|---|---|
| Principals | Two shareholder-employees active in the practice | $5,000 each | $10,000 |
| Associates | Three employed lawyers or accountants | $2,500 each | $7,500 |
| Support staff | Four clerks and administrators | $1,500 each | $6,000 |
| All classes | Nine people | $23,500 |
Spouses, common-law partners and children claim against the employee's limit, not a separate one. Write down the employment reason for each class. Our small business HSA guide walks through the class rules with another example and shows what does not work.
What the year costs on this plan
Suppose the firm uses 60% of its limits, which is $14,100 in approved claims, and the corporation is in Alberta, where GST applies to the administration fee only.
- Claims reimbursed: $14,100
- Frontier fee, 8% of approved claims: $1,128
- GST on the fee: $56.40
- Corporation pays: $15,284.40, deductible to the corporation
In a quiet year with no claims, the corporation pays $0. If everyone claims their full limit, the corporation pays $23,500 in claims, a $1,880 fee and $94 GST, for $25,474. Ontario firms also pay retail sales tax and the premium tax on this kind of plan; our post on HSA taxes by province has the rates, and the true cost of an HSA works through a full year.
How the published fees compare at this volume
These are published administration fees, before tax, checked November 9, 2026, on $14,100 of claims for nine members. The claims themselves are paid by the firm under every provider. Fee types are listed separately because a nine-person firm pays setup, annual and per-member charges differently from a one-owner plan.
- Frontier HSA: 8% of approved claims, no setup, annual or per-member fee. $1,128.
- Coastal HSA: 7% plus a one-time $50 setup fee. $1,037 in year one, $987 a year after that. Coastal collects the claim, fee and tax by pre-authorized debit.
- Olympia Group HSA: 8% plus a $335 setup fee, a $99 annual fee and $40 per member added. For nine members, $1,922 in year one, then $1,227 a year if no members are added. Olympia's $249 Basic plan is its flat-fee owner plan; the Group HSA is the offer priced for staff.
- EasyHSA: 10%, no setup or annual fee. $1,410.
- Wellbytes Pay-As-You-Use: 10%, no setup fee. $1,410.
- Kibono: $2.25 plus 5.25% per claim, plus payment processing of $1.50 plus 1.50% for debit or $0.30 plus 3.50% for cards. The total depends on how many claims the firm files, so work it out on your own count.
- Quikcard, myHSA and Canada Life HCSA: "typically" 12% for Quikcard, and quotes for the other two. We do not give totals from their published pages.
Said plainly: at this volume Coastal is cheaper than Frontier on administration fee, by $91 in year one and $141 a year after that. A firm with steady claims at this level should compare it seriously. Frontier's case is no fixed fees, nothing upfront, $0 in a quiet year, and no per-member line as students and associates come and go.
Who pays the employee, and when
An associate submits a receipt and we review it against the CRA's eligible expense rules. After approval, Frontier invoices the corporation for the claim, the fee and taxes. With automatic bank payments turned on, which is a pre-authorized debit verified once with two small deposits, the employee is paid as soon as the debit starts. With manual invoices, the employee is paid once the corporation pays the invoice. We do not promise a number of days. For a firm, we recommend automatic payments, so an associate's dental claim is not waiting on the month-end cheque run. The how it works page shows each step.
Running it from the practice manager's desk
The practice manager sets the classes and limits once and invites people. Each person submits their own receipts and follows their own claims. An articling student who is hired on is moved to the associate class; a leaver is removed. There is no per-member fee for either change, no payroll entries, and no contract. Our post on setting up an HSA without upfront funding explains why nothing is deposited.
Where another option fits better
- The firm needs life, disability or travel cover. An HSA reimburses expenses; it does not insure anyone. A group plan with a Health Care Spending Account inside it gives both, at a premium paid whether or not anyone claims.
- The partners want cover through the partnership itself. Frontier cannot be the sponsor for a partnership or LLP. The options are a group plan, a provider that serves partnerships, or each partner's own professional corporation.
- Claims are steady and well above $5,000 a year. On administration fee alone, Coastal's 7% costs less than Frontier's 8% after the setup year, and at this firm's volume in year one as well. Check its other terms, then decide.
- The firm is in Quebec. Frontier does not serve Quebec businesses, and Quebec treats HSA reimbursements as a taxable benefit provincially.
| Firm structure | Who a PHSP can cover | Frontier eligible? | What to do |
|---|---|---|---|
| Single professional corporation | Employees and active shareholder-employees | Yes, outside Quebec | Set classes by role; confirm each principal's employment |
| Partnership or LLP | Employees of the partnership, not the partners | No | Group plan or a provider that serves partnerships; ask your accountant |
| Partnership of professional corporations | Each corporation's shareholder-employee and its staff | The corporations, yes; the partnership, no | One plan per corporation; ask your accountant about the structure |
| Sole practitioner professional corporation | The principal, with the owner-only caveats | Reviewed before the plan starts | Read the accountant guide; confirm with your accountant |
What we recommend
For a law firm or accounting practice run through a professional corporation outside Quebec, we recommend a pay-per-claim HSA with limits by role for principals, associates and staff, dependants included, automatic payments on, and no contract. Frontier charges 8% of approved claims plus applicable taxes, and no other fee; on the nine-person plan above that is $1,128 on $14,100 of claims, and $0 in a quiet year. Look elsewhere in two cases: a partnership or LLP that wants to cover its partners through the firm itself, and a firm that needs insurance alongside the account. If claims are steady at this level, compare Coastal's lower percentage before you decide.
FAQ
Can partners in a law firm be covered by an HSA?
It depends on the structure. Partners in a partnership or LLP are generally not employees of the partnership, so a plan run by the firm covers associates and staff, not the partners. A partner who practises through their own professional corporation can be covered by that corporation's plan as a shareholder-employee, subject to the employment test.
Can principals have a higher limit than associates?
Yes, if the classes rest on documented employment criteria such as principal, associate and support staff, and the limits are reasonable for each role and its pay. Everyone in a class gets the same limit. A limit that tracks the person rather than the role puts the plan's PHSP status at risk, so document the reasoning and ask your accountant.
Can an articling student or junior be in a separate class?
Yes, as a class defined by role, which is the kind of employment criterion the CRA looks for. Give every student the same limit, write down why the class exists, have your accountant review it, and move people to the next class when their role changes.
Does an HSA work for a partnership of professional corporations?
Each professional corporation can run its own HSA for its shareholder-employee and any staff it employs directly, subject to the employment test and the owner-only plan caveats. The partnership itself can cover the employees it pays, but not the partners. Frontier serves the corporations, not the partnership. Ask your accountant how your firm is set up.
Is an HSA cheaper than group insurance for a small firm?
For dental, vision, paramedical and routine prescriptions, usually yes, because the firm pays only approved claims plus a fee and nothing in a quiet year. It is not a substitute for life, disability or travel insurance, which an HSA cannot provide. Price both against the claims you expect and the protection the firm needs.
Do partners need T4 income to qualify?
T4 salary or bonus is Frontier's preferred evidence that a shareholder-employee actively works in the corporation. It is not the only evidence. A principal paid only in dividends must provide other documentation of their role and have the corporate accountant confirm the arrangement before enrolling. Passive shareholders, and holding companies with no active employees, do not qualify.
