For self-employed Canadians, medical expenses are not automatically deductible from business income. The main business deduction is for qualifying premiums paid to an eligible Private Health Services Plan (PHSP) when CRA requirements are met.

Other eligible medical expenses may instead be claimed through the Medical Expense Tax Credit (METC). The right approach depends on your business structure, PHSP eligibility, employees, and the expenses involved.

Quick Notes

  • Sole proprietors cannot simply deduct personal medical bills as business expenses.
  • Qualifying self-employed individuals may be able to deduct eligible PHSP premiums.
  • Sole proprietors with no arm’s-length employees should not assume a Health Spending Account qualifies as a deductible PHSP.
  • Medical expenses not deducted as PHSP premiums may potentially qualify for the METC.
  • Incorporated professionals follow a different employer-benefit framework.

Self-Employed Medical Deductions in Canada

The term self-employed medical deductions can be misleading because there are two different tax treatments to consider.

A self-employed person may potentially:

  1. deduct qualifying PHSP premiums from self-employment income, or
  2. claim qualifying medical expenses through the personal Medical Expense Tax Credit.

These are not interchangeable, and the same amount cannot be claimed twice.

CRA allows qualifying self-employed individuals to deduct PHSP premiums when specific business, income, coverage, and contract requirements are satisfied. CRA — Self-Employed PHSP Deduction Guidance

Sole Proprietors and Health Spending Accounts

Sole proprietors need to distinguish between an HSA and the separate deduction available for qualifying PHSP premiums.

CRA specifically warns that where a sole proprietorship has no arm’s-length employees, it does not consider the HSA arrangement described in its warning to be a PHSP. Amounts paid to that type of account are not deductible business expenses.

That does not mean a self-employed person can never deduct health-plan costs. Qualifying PHSP premiums may still be deductible when the separate self-employed PHSP requirements are met.

PHSP Deduction vs. Medical Expense Tax Credit

PHSP Premium DeductionMedical Expense Tax Credit
Deduction from qualifying self-employment incomeNon-refundable personal tax credit
Applies to qualifying PHSP premiumsApplies to qualifying medical expenses
Subject to self-employed PHSP conditions and limitsSubject to METC eligibility and calculation rules
Reduces income when deductibleReduces federal tax otherwise payable
Cannot also be claimed as a medical expense if already deductedMay include eligible amounts not deducted as PHSP premiums

One option is not automatically better than the other.

If only part of a PHSP premium can be deducted, CRA states that the undeducted portion may potentially be included when calculating the Medical Expense Tax Credit.

Eligibility for the Self-Employed PHSP Deduction

CRA states that you may deduct qualifying PHSP premiums when the applicable conditions are met.

You must generally:

  • be actively engaged in your business on a regular and continuous basis
  • pay premiums to insure yourself, your spouse or common-law partner, or members of your household
  • meet the applicable income test
  • have coverage under a qualifying PHSP contract

For the income test, in the current or previous tax year, either:

  • your net self-employment income, excluding losses and PHSP deductions, must be more than 50% of your total income, or
  • your income from sources other than self-employment must be $10,000 or less

CRA also requires coverage under a qualifying contract with an eligible organization described in its self-employed PHSP guidance. Confirm the actual contract and all applicable conditions before claiming a deduction. Related: Canada.

Self-Employed PHSP Deduction Limits

The deduction is not automatically unlimited.

Under CRA’s published rules for the 2025 tax year, if you had no employees throughout 2025, the annual maximum generally uses:

  • $1,500 for yourself
  • $1,500 for your spouse or common-law partner
  • $1,500 for each insured household member age 18 or older at the start of the insured period
  • $750 for each insured household member under 18 at the start of the insured period

The maximum is also prorated based on the number of days the person was insured. Related: Canada.

These figures are PHSP deduction limits for the circumstances described by CRA, not universal HSA contribution limits.

Businesses With Employees

Different calculations apply when you have employees.

Where you had at least one qualified employee throughout 2025 and at least 50% of the insurable people in the business were qualified employees, CRA generally bases the maximum deduction on the cost of providing equivalent coverage to those employees.

If a qualified employee receives no coverage, CRA states that the proprietor cannot deduct their PHSP premiums from self-employment income in the described circumstances. Eligible premiums may potentially qualify as medical expenses instead. Related: Canada.

Medical Expenses That May Qualify

CRA recognizes many medical expenses, including certain:

  • dental and orthodontic services
  • prescription medications
  • prescription eyeglasses and contact lenses
  • practitioner services
  • medical devices
  • medical travel costs
  • attendant care and related qualifying services

Eligibility depends on the specific expense.

Some expenses require a prescription, certification, or other documentation. Practitioner eligibility can also vary by province or territory.

Health or wellness spending is not automatically a qualifying medical expense.

Incorporated Professionals Follow Different Rules

An incorporated professional is not treated the same way as an unincorporated sole proprietor.

A corporation may establish a qualifying HSA or PHSP for employees, including an owner who is also an employee when the applicable requirements are met.

Where the participant is a shareholder-employee, the benefit should genuinely be provided in the person’s capacity as an employee rather than simply because they own shares.

At the federal level, benefits provided under a qualifying PHSP are generally not taxable employee benefits. The compliance checklist likewise distinguishes qualifying PHSP benefits from ordinary employer-paid medical expenses.

A Practical Approach to Medical Deductions

1. Confirm Your Business Structure

Determine whether you operate as a sole proprietor, partnership, or corporation.

The applicable PHSP and HSA rules are different.

2. Determine Which Tax Treatment Applies

For self-employed individuals, determine whether you qualify to deduct PHSP premiums.

For other eligible medical costs, consider whether the Medical Expense Tax Credit applies instead.

3. Check Your Deduction Limit

Do not assume all PHSP premiums are deductible.

Your maximum can depend on your household coverage, insured period, employees, and the coverage provided to qualified employees.

4. Confirm Expense Eligibility

Check the CRA requirements for the specific medical expense and any practitioner, prescription, or documentation conditions.

5. Keep Supporting Records

Maintain PHSP contracts, premium records, receipts, prescriptions, certifications, and any other supporting documents relevant to the deduction or medical expense.

6. Avoid Double Claims

Do not claim the same amount both as a PHSP premium deduction and as a medical expense when CRA rules prohibit doing so.

Can a sole proprietor with no employees use an HSA?

CRA specifically warns that the HSA arrangement described in its guidance for a sole proprietor with no arm’s-length employees is not considered a PHSP. Separate self-employed PHSP-premium rules may still apply.

Are PHSP deductions unlimited?

No. CRA applies specific deduction limits and calculations depending on household coverage, the insured period, and whether the business has qualified employees.

Is a PHSP deduction always better than the Medical Expense Tax Credit?

No. The result depends on your income, premiums, medical expenses, business structure, and other tax circumstances.

Can an incorporated professional use an HSA?

Potentially, yes. Incorporated businesses can establish HSA benefits for eligible employees when the arrangement meets applicable PHSP requirements. Shareholder-employees require additional consideration of the employment relationship.
