MiAccounting | Tax Deductions, CRA, Medical Expenses, Tax Credits
Nobody enjoys paying more tax than necessary, which is why understanding available tax credits is crucial. One often-overlooked opportunity to reduce your tax bill is the Medical Expense Tax Credit (METC). By keeping track of your eligible medical expenses throughout the year, you can maximize your tax deductions when filing your return.
What Medical Expenses Can You Claim?
Certain medical expenses are commonly claimed, including:
- Prescription medications
- Dental treatments
- Vision care (glasses, contact lenses, laser eye surgery)
- Physiotherapy and chiropractic care
Beyond the basics, there are additional eligible medical costs that may surprise you, such as:
- CPAP machines and other assisted breathing devices
- Orthopedic braces and prosthetic devices
- Injection pens for medications like insulin
- Air purifiers and air conditioners (when prescribed for medical reasons)
Other expenses that may qualify:
- Private health insurance premiums
- Travel medical insurance
- Vitamin B12 injections (if prescribed by a medical professional)
- Medical travel expenses (see below)
Claiming Medical Expenses for a Disabled Dependent If you are supporting a disabled dependent, you may be eligible to claim additional medical expenses. The CRA allows claims for expenses related to the care and support of an individual with a disability, including:
- Home care services and personal support workers
- Mobility aids such as wheelchairs and walkers
- Accessibility modifications to your home (e.g., ramps, stairlifts, widened doorways)
- Specialized therapy services (e.g., speech therapy, occupational therapy)
- Costs associated with guide dogs or other assistance animals
You may also qualify for the Disability Tax Credit (DTC) in addition to medical expense claims, further reducing your tax liability. Claiming Travel Expenses for Medical Care if you must travel for necessary medical treatment, those costs may be eligible for a tax credit—especially for individuals in rural or remote areas. This includes trips for:
- Diagnostic tests
- Specialist consultations
- Surgeries
- Cancer treatments
To qualify, your travel must meet these CRA criteria:
- Equivalent medical services were not available near your home.
- You took a reasonably direct travel route.
- The trip was medically necessary under the circumstances.
Claiming Travel Expenses Based on Distance
- 40 km - 80 km (one way): Claim public transportation costs (or vehicle expenses if public transport was unavailable).
- Over 80 km (one way): You may also claim meals, accommodations, and parking fees.
How Much is the Medical Expense Tax Credit Worth? Medical expenses do not provide a dollar-for-dollar tax deduction but instead qualify for a non-refundable tax credit. This means they reduce the amount of tax you owe but do not lower your taxable income. For 2024, the allowable tax credit is 15% of eligible medical expenses, minus a deductible equal to the lesser of:
- 3% of your net income, or
- $2,759
Example Calculation Emma and Daniel incurred $4,500 in medical expenses. Emma’s income was $70,000, while Daniel’s was $50,000. Since Daniel has the lower income, his earnings are used to determine the deductible:
- Deductible = 3% of $50,000 = $1,500
- Eligible claim = $4,500 - $1,500 = $3,000
- Tax credit = $3,000 × 15% = $450 in tax savings
