The Canada Medical Expense Tax Credit (METC) is a personal tax credit—not a corporate tax credit. Business owners may claim qualifying medical expenses on their personal returns. Eligible health-plan premiums and employer-paid benefits follow separate business-deduction rules.
The starting point is to separate personal medical costs, self-employed health-plan premiums, and employee benefits. They do not belong in the same tax calculation.
Medical Expense Claims by Business Structure
| Situation | Potential tax treatment | Important distinction |
|---|---|---|
| An owner pays personal or family medical bills | Personal METC, subject to eligibility and thresholds | Not automatically a business expense |
| A qualifying self-employed person pays PHSP premiums | Deduction from self-employment income, subject to conditions and limits | Not the same as deducting personal medical bills |
| A corporation provides qualifying employee health benefits | Business-expense treatment under applicable tax rules | The corporation does not claim the personal METC |
A Private Health Services Plan (PHSP) is a health-benefit arrangement that meets applicable federal tax requirements. A Health Spending Account (HSA) can operate within that framework, but the HSA label alone does not establish eligibility.
How the Canada Medical Expense Tax Credit Works
The METC is a non-refundable credit that reduces personal income tax payable. It does not reduce taxable income or reimburse the full cost of treatment.
Under CRA’s METC guidance, individuals can claim qualifying expenses for themselves and certain family members. Running a business does not turn this personal credit into a corporate claim.
Federal Medical Expense Threshold for 2025
For yourself, your spouse or common-law partner, and your or your partner’s children under 18 at year-end, the calculation subtracts the lesser of 3% of your net income or $2,834 from eligible expenses. A positive remainder is used to calculate the credit; it is not the amount refunded.
Other eligible dependants require a separate calculation. Provincial and territorial credits also have their own rules.
Use the CRA’s calculation instructions for lines 33099 and 33199. The $2,834 figure applies to the 2025 tax year.
Sole Proprietors: Personal Claims and PHSP Deductions
A sole proprietor’s personal dental, prescription, or therapy bills do not become business expenses simply because business income paid for them. Qualifying costs may instead support a personal METC claim.
Separately, qualifying self-employed individuals may deduct PHSP premiums from self-employment income. Eligibility depends on business activity, income tests, the PHSP contract, employee coverage, and applicable deduction limits.
An amount deducted as a PHSP premium cannot also be claimed as a medical expense. An eligible undeducted portion may qualify for the METC.
Review the CRA’s self-employed PHSP deduction rules rather than assuming all health-plan payments are deductible.
Sole Proprietors Without Arm’s-Length Employees
CRA states that an HSA for a sole proprietorship with no arm’s-length employees is not considered a PHSP under the arrangement described in its warning, and payments to that account are not deductible business expenses.
This is distinct from the deduction available for qualifying PHSP premiums. See the CRA’s HSA warning for sole proprietors.
Incorporated Businesses and HSA Benefits
Corporations can provide eligible employees with health benefits through a qualifying PHSP, including an appropriately structured HSA.
Employer-paid qualifying health and dental benefits are generally deductible business expenses, subject to applicable rules. This is separate from the personal METC. Assigning an HSA allocation does not, by itself, establish a deductible payment.
Federally, benefits paid under a qualifying PHSP are generally non-taxable to employees. Ordinary employer reimbursement of medical bills outside a PHSP is generally taxable unless another exception applies.
The arrangement must meet CRA’s PHSP requirements, and claims must satisfy the plan’s eligibility, funding, and documentation rules.
Shareholder-Employees
For an incorporated owner, the benefit must be assessed as an employment benefit rather than assumed to qualify because of share ownership. The employment relationship and circumstances matter under CRA’s shareholder-benefit rules.
Quebec Employees
Quebec generally treats employer-paid PHSP coverage as a provincial taxable employee benefit, even where federal treatment is non-taxable. The benefit value is generally reported on the RL-1.
Review Revenu Québec’s PHSP taxable-benefit guidance rather than assuming HSA benefits are tax-free across Canada.
Eligible Medical Expenses and Supporting Records
Common qualifying categories include dental treatment, prescription vision care, qualifying prescription drugs, authorized practitioner services, and certain medical devices.
Requirements vary. Some expenses need a prescription or certification, and practitioner recognition depends on the province or territory where the service is provided.
Check the CRA’s medical-expense guide or the Wellbytes HSA Eligible Expenses Guide. An HSA does not expand the CRA’s list of qualifying medical expenses.
Steps to Claim Medical Expenses Correctly
1. Separate Personal and Business Records
Identify who paid each expense, who received the treatment, and whether the payment belongs to a personal claim, a PHSP-premium deduction, or an employer benefit.
2. Choose the Personal Claim Period
For a standard 2025 METC claim, eligible expenses may come from any 12-month period ending in 2025, provided they have not already been claimed.
For shared family expenses, compare which spouse or common-law partner can use the credit most effectively. Lower net income may help, but available tax payable also matters because the credit is non-refundable.
3. Account for Reimbursements
Generally, exclude expenses reimbursed—or eligible to be reimbursed—by insurance or an HSA from the personal METC claim.
CRA provides an exception when the reimbursement is included in income and is not deducted elsewhere. Apply the CRA’s reimbursement rules rather than claiming the same cost twice.
4. Keep the Required Documents
Retain receipts, prescriptions, certifications, reimbursement statements, and relevant PHSP records. Use the appropriate personal-return lines or business-expense reporting for the treatment that applies.

Frequently Asked Questions
Can a corporation claim the Canada Medical Expense Tax Credit?
No. The METC is a personal credit. A corporation’s qualifying employee health-benefit costs follow business-deduction rules instead.
Can I claim medical expenses below the METC threshold through an HSA?
Potentially. Personal METC income thresholds are not HSA reimbursement minimums. HSA claims depend on the qualifying plan’s terms, eligible expenses, available allocation, and documentation.
Does an HSA always provide greater savings than the METC?
No. The result depends on business structure, income, expenses, plan costs, and provincial rules. An HSA is an employee-benefit arrangement, not a corporate version of the METC.
