The personal medical expense tax credit (METC), a corporation’s employee-benefit deduction and a self-employed Private Health Services Plan (PHSP) premium deduction are different tax mechanisms. Identify who paid, who received the benefit, whether the expense was reimbursed and which tax year applies before choosing a claim.
The personal credit reduces tax payable
An eligible individual claims the METC on a personal return. It does not reduce a corporation’s taxable income and is not a deduction equal to the full medical bill. The eligible unreimbursed expense, applicable threshold, credit rate and available tax payable determine its value.
A clearly stated federal example for 2025
Assume $4,000 of eligible unreimbursed expenses for the individual, spouse or common-law partner, or minor children, and $50,000 of the relevant net income. The 2025 federal threshold is the lesser of 3% of net income and $2,834. Three per cent of $50,000 is $1,500, so the illustrative credit base is $4,000 − $1,500 = $2,500.
The $2,500 is a credit base, not the tax refund or an income deduction. Apply the tax year’s credit rate and tax-payable limits separately. Other dependants use their own applicable net-income threshold. Provincial credits, including Québec’s, require a separate calculation.
Incorporated employers and PHSP benefits
An employer may deduct qualifying employee-benefit costs, subject to the plan, business purpose, reasonableness and applicable timing rules. Eligible employee reimbursements under a qualifying PHSP can receive favourable federal tax treatment. Where an individual is both an employee and a shareholder, the capacity in which the benefit is received matters.
Incorporation alone does not establish eligibility or guarantee a deduction. Québec has separate provincial treatment and reporting for employer-paid private health benefits. Keep employer deductibility, federal employee treatment and Québec valuation/reporting distinct.
Sole proprietors need a separate analysis
CRA warns that the self-insured HSA arrangement described in its warning does not qualify for a sole proprietorship with no arm’s-length employees. Separately, qualifying self-employed PHSP insurance premiums may be deductible under section 20.01 if its conditions and limits are met. Personal eligible unreimbursed expenses may instead be relevant to the METC.
Prevent double claims
Identify reimbursements from a PHSP or another plan before preparing a personal medical-expense claim. An amount already reimbursed is not automatically available for a second personal credit. Check the applicable inclusion and reimbursement rules rather than treating the same bill as both a full reimbursement and a separate deduction.
Compare complete costs
When comparing an HSA with personal payment or insurance, include the funded reimbursement, administration, applicable taxes and actual insurance protection. A personal marginal tax rate does not establish the corporation’s deduction value or a verified customer saving.
Under the current Wellbytes Pay-As-You-Use model, administration is 10% of eligible reimbursed amounts, plus applicable taxes. Prepaid pricing follows the accepted rate and annual funding amount. Historical customer prices require their own dated agreement or invoice.
Prepare the records
- Identify the payer, participant, relationship and relevant province.
- Use the correct tax year and current filing instructions.
- Check the precise medical-expense category and required prescription, certification or practitioner authorization.
- Retain itemized receipts, reimbursements, plan terms, invoices and payment records.
- Keep the personal credit, employer deduction and self-employed premium deduction in separate calculations.
