5 Tax Lessons They Definitely Didn't Teach You in High School

Between calculus and gym class, most of us missed the "How to Canada" curriculum—especially when it comes to the CRA. Taxes are a lifelong habit, and starting early is the best way to make sure you aren't leaving free money on the table.

1. There is no "minimum age" to pay taxes.

In Canada, the CRA doesn't care if you're 16 or 65; it’s all about how much you earn. If your boss takes tax off your cheque but you make less than the "basic personal amount" (around $15,000+), that money isn't gone—it’s just on hold. You have to file a return to get that cash back as a refund.

2. Your tuition is a "future-proof" tax break.

Being a student is expensive, but your tuition acts like a savings account for your future self. If you don't earn enough to use your Tuition Tax Credits this year, you can "carry them forward." This means when you’re finally working that high-paying dream job, those old school receipts will swoop in to slash your tax bill.

3. The deadline only "hurts" if you owe money.

The magic date is April 30th. If you’re getting a refund, there’s no penalty for filing late—but you’re basically giving the government an interest-free loan of your own money. However, if you owe the CRA, missing the deadline triggers immediate late-filing penalties. Even if you can’t pay the full bill yet, filing on time stops those extra fees from stacking up.

4. You’re eligible for more than just "student" credits.

Just because you're under 25 doesn't mean you're stuck with basic credits. If you moved for school or work, those moving expenses might be deductible. If you have a side hustle, your self-employment expenses (like your laptop or phone) count too. If you aren't rolling in cash, you should at least be rolling in credits.

5. Mistakes aren't permanent (usually).

Panic-typed a number wrong? The CRA actually lets you request changes to your returns from up to 10 years ago. Once you get your official Notice of Assessment (NOA), you can file an adjustment. If they approve it, they’ll send you a "Notice of Reassessment" and any extra cash you were owed.
