7. Common Mistakes to Avoid with Health & Dental B

Figuring out CRA rules can feel confusing, and even tiny mistakes can lead to tax audits or make you miss out on valuable savings. Here are the most common slip-ups to watch out for and avoid:

Mistake 1: Reporting non-taxable employer premiums as income: Most health and dental benefits from your job are tax-exempt—only report benefits that are clearly labeled as taxable on your T4 slip

Mistake 2: Forgetting to claim medical expense credits: Out-of-pocket dental costs can pile up fast, and this credit often cuts down the tax bill for low and middle-income families

Mistake 3: Quebec residents brushing off provincial taxable benefits: If you skip reporting employer-paid premiums on your RL-1 slip, you could face penalties from Revenu Québec

Mistake 4: Misusing HSA funds: Taking cash out of your Health Spending Account counts as taxable income, so only use this money for eligible medical expenses

Mistake 5: Misplacing receipts: The CRA requires detailed receipts for every medical expense claim—keep digital or paper copies for 6 years just to be safe

8. Final Takeaways: Do You Pay Tax on Health & Den

For 90% of working Canadians outside Quebec, the answer is no—standard employer-sponsored health and dental benefits that fall under a PHSP are totally tax-free, and you don’t have to report premium contributions or reimbursements as part of your income. For folks living in Quebec, employer-paid premiums are taxable on your provincial tax return (but not for federal taxes), so you’ll need to include that amount when filing provincially.

Taxable benefits are pretty uncommon and only apply in specific situations—like cash withdrawals from an HSA or coverage for non-medical expenses. And government dental programs such as the CDCP are always tax-free, no strings attached. Plus, don’t sleep on the medical expense tax credit for out-of-pocket costs—it’s an easy way to lower your tax bill and get back some of what you spent on dental care.

To stay on the right side of the rules, check your T4 or RL-1 slip carefully, hang onto all detailed receipts for medical and dental expenses, and talk to a tax pro if you have a non-standard plan (like a self-employed PHSP or flexible HSA). Once you understand these rules, you can make the most of your health and dental benefits without dealing with costly tax errors.

If you’re not sure whether your benefits are taxable, just reach out to your company’s HR team or a licensed tax advisor—they can clear up any confusion about your obligations and make sure you’re claiming every tax break you qualify for when it comes to healthcare costs.
