⚡ Key Takeaway
The CRA estimates billions of dollars in eligible credits go unclaimed every year. Most Canadians only claim the basics — RRSP and basic personal amount — and leave significant money on the table.
Why Canadians Miss Tax Credits
Canada's tax code contains dozens of refundable and non-refundable credits — but you only receive them if you claim them. DIY software helps if you know what to look for, but most Canadians don't. Here are 12 credits that consistently go unclaimed.
The 12 Most Missed Credits
1. Disability Tax Credit (DTC)
One of the most valuable and most overlooked credits in the Canadian tax system. Worth up to $8,870 federally (2025) for adults with qualifying physical or mental impairments. Must be certified by a medical practitioner on Form T2201. Retroactive claims possible for up to 10 years.
2. Canada Workers Benefit (CWB)
A refundable credit for low-to-moderate income working Canadians. Many filers earning under $35,000 qualify but never claim it because it requires filing a return and completing Schedule 6. The CWB also now includes advance payments — check your CRA My Account.
3. Medical Expense Tax Credit
Claimable for medical expenses exceeding 3% of net income (or $2,635 — whichever is less). Most people think only prescriptions count, but the CRA list includes: dental work, glasses, physiotherapy, chiropractic, attendant care, service animals, gluten-free food (celiac), and over 100 other items. Claim the higher-income spouse's expenses for a bigger credit.
4. Tuition Amount Transfer
Students who can't use their full tuition credit can transfer up to $5,000 to a parent, grandparent, or spouse. Many families miss this because the student files first and simply carries forward the credit without considering the transfer benefit.
5. Caregiver Credits
Three overlapping credits for Canadians caring for a dependent with a physical or mental impairment: the Canada Caregiver Credit, Eligible Dependant Amount, and Infirm Dependant Credit. Often missed because the dependent may not be a child and may not live with you.
6. Home Buyers' Amount
First-time buyers (or those who haven't owned a home in the past 4 years) can claim a $10,000 non-refundable credit — worth up to $1,500 in tax savings. Frequently missed because it's claimed in the year of purchase and buyers are busy with the move.
7. Volunteer Firefighter / Search & Rescue Credit
A $3,000 non-refundable credit for Canadians who volunteer at least 200 hours per year as a firefighter or search and rescue volunteer. Almost universally unclaimed.
8. Adoption Expense Credit
Eligible adoption expenses up to $18,210 per child can be claimed in the year the adoption is finalized — agency fees, legal fees, translation fees, and travel. Often missed due to the complexity of the year it's claimable.
9. Digital News Subscription Credit
Up to $500 in qualifying Canadian digital news subscriptions (Globe and Mail, Toronto Star, etc.) generates a 15% federal credit — up to $75 in savings. Small but consistently unclaimed.
10. Union & Professional Dues
Employment-related union dues, professional association fees, and licensing fees are fully deductible against employment income. Many salaried employees overlook this on their T4 (box 44) or forget to claim dues paid separately.
11. Moving Expense Deduction
If you moved at least 40 km closer to a new job or school, eligible moving costs (movers, travel, temporary accommodation, real estate fees) are deductible against income earned at the new location. Frequently missed by graduates moving for their first job.
12. Climate Action Incentive (CAI)
A quarterly refundable payment for residents of provinces subject to the federal carbon price (Ontario, Alberta, Saskatchewan, Manitoba, and others). Must be claimed on your T1 return — it is not automatically paid. Rural residents receive a 20% supplement.
