7 Underused Tax Deductions to Boost Your Canadian Tax Refund

Tax season often feels overwhelming, but for Canadian families, it also presents a valuable opportunity. While many people focus on the basics, there are several lesser-known deductions and credits that can significantly boost your refund or reduce the amount you owe.

Many families assume these benefits are only for low-income households, but the reality is that middle-income families often benefit the most—especially when multiple credits are combined.

Here are seven tax deductions and credits to review before filing your 2026 return.

1. Child Care Expense Deduction

If you pay for childcare so you or your spouse can work, study, or run a business, you can deduct those costs from your income. This is one of the most substantial deductions available to working parents.

Eligible expenses include:

• Daycare or nursery school fees
• Nannies or babysitters (with proper documentation)
• Day camps (note: overnight camps are not eligible)

Typical maximum deductions per child:

• Up to $8,000 for children under 7 years old
• Up to $5,000 for children aged 7 to 16
• Up to $11,000 for children with disabilities

This deduction is claimed by the parent with the lower net income, so plan accordingly to maximize the benefit.

2. Canada Caregiver Credit

If you support a dependent with a physical or mental impairment, you may be eligible for the Canada Caregiver Credit. This non-refundable credit can be worth several thousand dollars depending on your situation.

You can claim it for:

• Children
• Parents or grandparents
• Other dependent relatives

Common misconception: Many families miss this credit because they assume the dependent must live with them or be elderly. However, you may still qualify if the dependent relies on you for support, even if they don’t live in your home.

3. Medical Expense Tax Credit

While we hope our families stay healthy, medical costs can add up quickly. Fortunately, you can claim eligible medical expenses not covered by insurance.

Examples of claimable expenses:

• Prescription medications
• Dental work and orthodontics (braces)
• Vision care (glasses, contacts, laser eye surgery)
• Therapy or mobility aids
• Travel costs for necessary medical treatment

The threshold: You can claim medical expenses once they exceed the lesser of 3% of your net income or approximately $2,885 (this amount is indexed annually).

Pro Tip: You can choose which spouse claims the medical expenses. By combining family medical expenses on one return, you can reach the threshold faster and maximize the credit.

4. Tuition Tax Credit Transfer

As your children grow up and head to college or university, they accumulate tuition tax credits. However, full-time students often don’t earn enough income to utilize all these credits immediately.

If your child doesn’t need all of their tuition credit, they may transfer up to $5,000 of unused tuition credits to a parent (or grandparent). This is one of the most commonly overlooked tax savings for families with post-secondary students.

5. Canada Training Credit

For adults aged 26–65, the Canada Training Credit helps offset the cost of professional development. If you take courses, workshops, or training programs to improve your skills, you can claim a refund of up to 50% of eligible tuition costs.

This applies to both university courses and eligible vocational training. Even small courses can generate a refund, so be sure to check your CRA account to see your accumulated credit limit.

6. Home Accessibility Tax Credit

If your family is renovating your home to accommodate a senior or a person with a disability, you may qualify for the Home Accessibility Tax Credit. This is a non-refundable credit that can significantly reduce your tax bill.

Eligible upgrades include:

• Installing wheelchair ramps
• Installing walk-in bathtubs
• Widening doorways for accessibility
• Adding grab bars in bathrooms

You can claim up to $20,000 in qualifying renovation expenses per year. This credit is vital for families looking to keep loved ones safe and comfortable at home.

7. Eligible Dependant Credit

Single parents or caregivers supporting a dependent may claim the Eligible Dependant Credit (often called the “equivalent to spouse” credit) if they are not claiming a spouse.

This credit can be worth thousands in tax reduction, yet many single parents overlook it because they assume it only applies to married couples. If you are the primary caregiver for a child or dependent relative and live alone, this credit is designed for you.

Pro Tip: Don’t Leave Money on the Table

Many Canadian families miss refunds because they assume tax credits apply only to low-income households. In reality, middle-income families often benefit the most when multiple credits are combined.

For example, a family might combine the Child Care Expense Deduction with the Medical Expense Tax Credit to significantly lower their taxable income.
