💡 The CRA Spousal Rule: Under the Income Tax Act, either spouse may claim the family's medical expenses regardless of who paid the bill. Having the lower-income spouse claim maximizes your tax credit by lowering the 3% deduction floor.

Complete Guide to the CRA Medical Expense Tax Credit (METC)
The Medical Expense Tax Credit (METC) is a non-refundable tax credit provided under Section 118.2 of the Canadian Income Tax Act. It is designed to assist Canadian families burdened by high unreimbursed healthcare, dental, and medical costs.
1. How the 3% Statutory Threshold Works
You cannot claim 100% of your medical expenses; rather, the CRA only allows you to claim expenses that exceed your minimum threshold floor:
For example, an individual earning $50,000 net income has a 3% threshold of $1,500. If they have $4,000 in qualifying medical bills, they can claim $2,500 ($4,000 - $1,500). That $2,500 claimable amount generates a 15% federal tax credit ($375) plus their provincial credit (~$126 in Ontario), saving over $500 on their tax bill.
2. The Spousal Optimization Rule (Strategic Tax Planning)
Under Canadian tax law, medical expenses for yourself, your spouse or common-law partner, and your dependent children under 18 can be combined and claimed entirely by one spouse, regardless of who paid the receipts.
Because the 3% deduction floor is tied directly to the claimant's net income, having the spouse with the lower net income claim the expenses yields a smaller non-claimable floor, a larger qualifying expense balance, and therefore a significantly higher tax refund for the household.
3. Commonly Overlooked Eligible Medical Expenses
- Private Health Insurance Premiums: Monthly premiums paid to private health and dental plans (including deductions made by your employer on your pay stubs).
- Orthodontics and Dentures: Braces, aligners, crowns, implants, and major restorative dental work not covered by private insurance.
- Prescription Eyewear: Contact lenses, prescription glasses, and laser eye surgery.
- Medical Travel (>40 km & >80 km): If medical treatment is unavailable locally, travel expenses over 40 km one-way are deductible (fuel, parking), and accommodation/meals are deductible if traveling over 80 km.
- Fertility Treatments: IVF, donor fees, and associated medications.
Frequently Asked Questions
Is the Medical Expense Tax Credit refundable? ▼
The standard METC is non-refundable (it reduces your tax payable to zero, but will not create a cash refund beyond tax withheld). However, low-income working Canadians may also qualify for the Refundable Medical Expense Supplement (Line 45200), which provides up to $1,464 in direct cash refunds.
Can I claim expenses paid for a dependent parent or grandparent? ▼
Yes. You can claim medical expenses for other adult dependants (parents, grandparents, adult children) on Line 33199. The calculation is based on the dependant's own net income with their own 3% threshold.
Do I need to mail receipts to the CRA when filing? ▼
No. If you file electronically via NETFILE, do not send receipts. However, the CRA routinely reviews medical expense claims during post-assessment processing, so you must retain all receipts, prescription slips, and insurance explanation of benefits (EOBs) for at least 6 years.
