CRA Medical Expenses: What Canadian Business Owners Need to Know

Under section 118.2 of the Income Tax Act and CRA guidance, many medical expenses can qualify if they fit the statutory category, are supported by receipts, and are not reimbursed or reimbursable elsewhere. Depending on the expense, the rule may also require a prescription or an authorized medical practitioner. These rules matter both for the Medical Expense Tax Credit (METC) on personal returns and for reimbursements through a compliant Private Health Services Plan (PHSP) such as a Health Spending Account. If you run an incorporated business in Canada, understanding how CRA defines, tracks, and limits medical expenses directly affects how much you save.

What does the CRA consider eligible medical expenses?

CRA's eligible medical expense rules are broader than many business owners expect. The main references are Income Tax Act section 118.2 and CRA Guide RC4065 — Medical Expenses.

Common examples include:

• dental work, including exams, fillings, crowns, and orthodontics
• prescription drugs that meet the Income Tax Act and CRA recording requirements
• physiotherapy, chiropractic care, and some massage therapy claims, depending on the province and the practitioner's CRA status
• vision care such as eye exams, prescription glasses, and contact lenses
• mental health services and counselling where the provider is authorized for the province or territory
• medical devices such as hearing aids and wheelchairs; some devices require a prescription
• fertility-related expenses that meet the tax rules
• certain lab tests, imaging, and specialist services

Two rules catch business owners off guard most often. First, province matters for practitioner-based expenses: an expense that qualifies in Ontario may not qualify in Alberta or Quebec. Second, purely cosmetic medical or dental services are generally not eligible, although medically necessary or reconstructive procedures may still qualify.

For the full expense-by-expense breakdown, see the HSA eligible expenses list.

Can you carry forward medical expenses with CRA?

CRA does not allow an open-ended carry-forward for medical expenses. Instead, the METC uses a 12-month claim window.

You can claim eligible medical expenses paid in any continuous 12-month period that ends in the tax year you are filing. The expenses must not have been claimed by you or anyone else for a previous year.

Example for a 2025 return:

Claim period	Valid?
July 1, 2024 to June 30, 2025	Yes
January 1, 2025 to December 31, 2025	Yes
A period ending in 2024	No — wrong tax year

This is why people describe METC timing as a "carry forward" even though it is really a claim-period selection rule. You cannot bank a receipt indefinitely and use it in a future year. If an expense falls outside every valid 12-month window for a given return, it is gone.

Why period selection matters: The METC only applies to the portion of eligible expenses above a threshold — the lesser of 3% of your net income or the CRA fixed limit ($2,834 for 2025 returns, indexed annually). Comparing two possible 12-month windows before filing can materially change the claim value.

Option	12-month period	Eligible expenses	Threshold (3% of $87,000 income)	Amount above threshold
A	Jan 1 – Dec 31, 2025	$4,200	$2,610	$1,590
B	Jul 1, 2024 – Jun 30, 2025	$5,150	$2,610	$2,540

Option B captures an extra $950 in claimable base simply by shifting the window.

How do you track medical expenses for CRA?

A simple medical-expenses worksheet is just a tracking spreadsheet you create yourself to organize receipts before filing. A well-structured worksheet lets you separate PHSP/HSA-reimbursed expenses from personal METC claims, track your threshold math, and stay audit-ready.

Use this column structure in a spreadsheet:

Date paid	Expense category	Provider	Amount	Eligible under ITA 118.2?	Reimbursed by PHSP/HSA?	Claim on line 33099/33199?	Notes
2025-01-15	Physiotherapy	ABC Physio Clinic	$220	Yes	Yes	No	PHSP claim #1024
2025-02-03	Prescription drug	Main St Pharmacy	$148	Yes	No	Yes	Keep Rx copy
2025-02-18	Massage therapy	Wellness Co.	$130	Province-dependent	No	Pending	Verify practitioner eligibility

Below the transaction rows, add a summary block:

• HSA-reimbursed total: $2,140
• METC-eligible expenses: $3,870
• METC threshold: $2,450
• Estimated claimable METC base: $1,420

This split is the practical output of the worksheet: a clean separation between what the corporation already handled and what remains for the personal return. Each receipt should have exactly one claim path — either corporate reimbursement through a PHSP/HSA, or personal METC. Never both.

Common worksheet mistakes:

• treating your worksheet as an official CRA form
• mixing personal and corporate expenses in one uncategorised total
• failing to mark whether a receipt was already reimbursed through PHSP/HSA
• missing province-specific practitioner eligibility checks

Which medical practitioners are authorised by CRA?

For practitioner-based claims, the provider must be authorized to practise under the laws of the province or territory where the service is provided. CRA maintains a reference page listing authorised medical practitioners by province.

In practical terms, the claim usually needs all of the following to be true:

1. The service itself is a CRA-eligible medical expense
2. If the category requires it, the provider is licensed or otherwise authorized in that province or territory
3. Your receipt includes enough detail to verify provider identity, date, amount, and service type

The most frequently claimed practitioner-based categories are:

• physiotherapy, massage, and chiropractic
• mental health therapy and counselling
• prescription-related care (pharmacist dispensing)
• physician and specialist services

For each claim, keep documentation clear enough that an auditor can confirm who provided care and why the service qualifies. At minimum, every receipt should include the provider's full name and clinic name, the service date (not just the invoice date), a description of the service rendered, the amount paid, and the provider's registration or licensing details where required.

Does practitioner eligibility vary by province?

Yes — and this is where many claims get denied. Two identical treatments with the same dollar amount can have different claim outcomes depending on the provider's credentials in that jurisdiction.

Practitioner type	Ontario	Alberta	British Columbia	Quebec
Registered massage therapist	Eligible	Not eligible	Eligible	Not eligible
Physiotherapist	Eligible	Eligible	Eligible	Eligible
Psychologist	Eligible	Eligible	Eligible	Eligible
Naturopath	Eligible	Eligible	Eligible	Not eligible
Acupuncturist	Eligible	Eligible	Eligible	Not eligible

The most notable gap: massage therapy is not eligible in Alberta because registered massage therapists are not listed by CRA as authorized medical practitioners there. A massage receipt from an Alberta RMT would generally not qualify for METC or a compliant PHSP/HSA reimbursement, while the same receipt from an Ontario RMT would generally qualify.

This is also why copying "eligible lists" from random websites is risky. Your claim outcome depends on the exact provider, location, and documentation — not just the procedure name. When in doubt, confirm your provider's status against CRA's authorised practitioners page before treatment, especially for less common service categories.

How do HSAs and the METC interact?

Business owners with a compliant Health Spending Account often ask whether they can also claim those same expenses on their personal METC. The short answer: no. Expenses reimbursed or reimbursable through a PHSP/HSA generally cannot be claimed again under the METC.

For each receipt, you choose one path:

• Corporate reimbursement through PHSP/HSA — the reimbursement is generally non-taxable to the employee if the plan is compliant
• Personal METC claim — you claim the expense on line 33099 or 33199, subject to the 3%-of-net-income threshold

The METC route is threshold-limited: you only get tax relief on the amount above the lesser of 3% of net income or $2,834 for 2025 returns. A PHSP/HSA reimbursement is not subject to that threshold.

Example: incorporated owner with $4,800 of eligible expenses

Claim path	Amount	Tax treatment
Reimbursed through PHSP	$2,900	Generally non-taxable to employee
Paid personally, not reimbursed	$1,900	Tested against METC threshold on personal return

Only the unreimbursed $1,900 can be included in the METC calculation. The $2,900 already went through the corporate health plan route.

For many incorporated owners, the "carry forward" question is really a planning question: should this expense go through the corporation via a compliant PHSP, or through the personal return via METC? When expenses are recurring or material, that decision can change your after-tax outcome significantly. For a side-by-side savings framework, see the HSA tax guide for corporations.

FAQ

Is there a CRA medical expenses worksheet I can download? No standard worksheet is required. A simple self-made spreadsheet is usually enough to organize receipts, separate PHSP/HSA reimbursements from personal claims, and keep your records in order.

What is the METC threshold for 2025? The lesser of 3% of your net income or $2,834. This threshold is indexed annually by CRA. You only receive tax relief on the eligible expenses above this amount.

Can I claim medical expenses from 2024 on my 2025 return? Yes, if those expenses fall within a continuous 12-month period ending in 2025 and were not already claimed on a previous return. For example, expenses paid between April 1, 2024 and March 31, 2025 would be valid.

Do HSA and METC use the same practitioner rules? They rely on the same underlying medical-expense rules, but the exact requirement depends on the expense category. Some items need an authorized practitioner, some need a prescription, and some depend on other CRA conditions.

What happens if my METC claim is audited? CRA may request receipts, proof of payment, and evidence that the practitioner was authorized where that matters for the expense. Keep records for at least six years after the tax year in question.

Can my corporation deduct medical expenses directly without an HSA? A corporation can pay or reimburse medical expenses, but if the arrangement is not a compliant PHSP, the payment is generally treated as a taxable benefit to the employee rather than a tax-free health benefit.
