Claiming your dependant's medical expenses
You can claim a non-refundable tax credit for medical expenses you paid in the year for your dependants. A dependant can be your or your spouse’s or common-law partner’s:
- Child or grandchild who was 18 years of age or older on December 31, 2022*
- Parent or grandparent
- Brother or sister
- Uncle or aunt or
- Niece or nephew
In order to be eligible, your dependant must have relied on you for support and lived with you during the year. If your dependant didn’t live with you, he or she must have been a resident of Canada at some time during the year. The residency requirement doesn’t apply to your or your spouse’s child or grandchild.
*Note: If you want to claim medical expenses for a child under 18, you can combine these with any medical expenses you paid for yourself and/or your spouse or common-law partner, on your tax return. Refer to our Medical expenses article for more information.
You can claim the total of the eligible expenses you paid minus whichever is less:
- $2,479 or
- 3% of your dependant's net income
You can only claim medical expenses for which you or someone else have not been or will not be reimbursed. For example, if your health insurance plan reimbursed you for 80% of your dependant’s medical expenses, you can only claim the remaining 20% on your return (minus $2,479 or 3% of your dependant’s net income).
Keep in mind, the medical expenses you’re claiming can’t be used to calculate any other credit, including the disability supports deduction. Additionally, your dependant needs to claim the medical expenses on his or her return first. Any unused medical expenses can then be claimed by you.
You can claim expenses for any 12-month period ending in the tax year for which you’re filing a return. This means, for the 2022 tax year, you could claim expenses paid in 2021 and in 2022.
Tax tip: While it is usually more beneficial for the lower income spouse to claim the family’s medical expenses, when it comes to unused medical expenses from dependants over the age of 18, it might be better for the higher income spouse to claim this amount.
Some common eligible medical expenses that you might be able to claim are:
- Medical services provided by qualified medical practitioners (includes diagnostic, therapeutic or rehabilitative services provided by a medical practitioner acting within the scope of his or her professional training)
- Fees paid to a medical practitioner to complete health and disability forms
- Dentist and dental services
- Prescription drugs and medications
- Medical marihuana, including marihuana plants or seeds, cannabis or cannabis oil if you’re authorized to possess these substances, for your own medical use (under the Access to Cannabis for Medical Purposes Regulations or section 56 of the Controlled Drugs and Substances Act)
- Ambulance service to or from a hospital
- Prescription eyeglasses and prescription contact lenses
- Laboratory tests and x-rays
- Diabetic testing supplies
- Premiums for private health insurance plans, including those you paid through payroll deductions (premiums for mandatory provincial health plans, such as the British Columbia medical services plan, are not claimable)
- Travel expenses paid to access medical services that was at least 40 km away from your home
- Cost to adapt a van to transport a person who needs a wheelchair

Important: Before you begin, make sure that you’ve told us about your dependants, then follow these steps to claim their medical expenses:
You’ll only see a difference in your refund or tax owing amount if you have a significant amount of medical expenses. The amount paid in medical expenses must exceed the least of the following amounts:
- $2,479 or
- 3% of your dependant’s net income
For example, let’s say on October 1st 2022, you paid $300 for your dependant’s prescription glasses and that was your only medical expense for the year. Since the medical expense is less than 3% of your dependant's net income, entering this amount on your 2022 tax return won’t make a difference to your refund or tax owed.
2022 dependant net income |
$15,000 |
Less $2,479 or 3% of dependant’s net income (whichever is less) |
- ($15,000 X 3%) = $450 |
Allowable medical expenses claim |
$300 - $450 = –$150 (a negative amount can’t be claimed) |
However, since medical expenses paid in any 12-month period ending in the tax year can be claimed, you might be able to combine the above expense amount with other medical expenses you’ll have next year and claim it on that year’s return.
Let’s say you paid $2,000 for your dependant’s medical expenses from October 1, 2022 to October 1, 2023. Provided these expenses have not been claimed before, you’ll be able to claim the following amount in medical expenses on your 2023 return:
2023 dependant net income |
$15,000 |
Less $2,479 or 3% of dependant’s net income (whichever is less) |
- ($15,000 X 3%) = $450 |
Allowable medical expenses claim for 2023 |
$2000 - $450 = $1,550 -- claimable amount for 2023 |
