Summer is when a lot of young Canadians earn their first real paycheque — a job at a camp, a retail shift, a landscaping crew, an internship. And it’s usually the moment a parent asks me some version of: “Does my kid need to file taxes? They barely made anything.” It’s a fair question, and the answer surprises people.

Here’s the short version: most students earning summer-job money will owe little or no income tax, thanks to a credit that shelters a substantial amount of income. But “you don’t owe tax” and “you shouldn’t file” are two very different things — and treating them as the same is one of the most common, and costly, mistakes students make. As a CPA, I’d argue filing is more important for students than for many higher earners, precisely because of what filing unlocks. Let me walk through why.

Will a Student Actually Owe Tax? Usually Not

The reason most students owe no federal income tax is the basic personal amount (BPA) — a non-refundable credit every Canadian resident can claim. For 2026, the federal BPA is $16,452. In plain terms, that means the first $16,452 of income is effectively free of federal income tax. A student who earns $8,000 flipping burgers or lifeguarding over the summer is comfortably below that line and will owe no federal tax on those earnings.

Each province has its own BPA on top of the federal one, and they vary widely — from around $12,000 in some provinces to over $22,000 in Alberta — so the exact point at which provincial tax begins depends on where you live. But for a typical student with part-time or summer earnings, both the federal and provincial thresholds usually leave the income untaxed.

There’s an important distinction to understand here, because it explains a lot of student confusion: income tax is not the only thing deducted from a paycheque. Even when a student owes no income tax, an employer is still required to deduct CPP contributions (on earnings above the $3,500 annual exemption) and EI premiums from their pay. Those are separate from income tax and aren’t refunded just because the student’s income is below the BPA. So a student can look at their pay stub, see deductions, and assume they’re “paying tax” — when in fact those deductions are CPP and EI, not income tax.

Why Deductions on the Paycheque Often Mean a Refund Is Waiting

Here’s where filing starts to pay off directly. Many employers calculate income tax withholding on each paycheque as though that rate of pay will continue all year. A student earning $600 a week at a summer job may have income tax deducted as if they were earning that amount for 52 weeks — pushing them past the BPA — when in reality they only work 14 weeks over the summer and earn far less than the threshold.

The result: income tax was withheld from their pay during the summer, but because their total annual income falls below the BPA, they owe none of it. That withheld tax is refundable — but only if they file a return to claim it. Every year, students leave real money with the CRA simply because nobody told them to file. For a student who had a few hundred dollars of income tax withheld over the summer, filing is often the difference between getting that money back and losing it entirely.

This alone is reason enough to file. But it’s not the biggest reason.

The Real Reason to File: What It Unlocks

Even a student who had zero tax withheld and is owed no refund should still file. Filing a return does several things that have nothing to do with whether tax is owed, and these are where the long-term value lies.

It builds RRSP contribution room. RRSP room accumulates at 18% of your prior year’s earned income, and employment income from a summer job counts. Filing a return is what reports that earned income to the CRA and generates the contribution room — which then carries forward indefinitely. A student who files every year they work, starting at 16, can accumulate years of RRSP room they can use later, when they’re earning a professional salary and the deduction is worth far more. Skip filing, and that room simply never gets created. It’s one of the quietest but most valuable reasons to file early.

It triggers benefit and credit payments. Several government benefits are income-tested and paid based on your filed return. The GST/HST credit is the big one for students: once a student turns 19, they’re generally eligible to receive it — but only if they’ve filed a return. It’s a quarterly, tax-free payment that can total several hundred dollars a year, aimed squarely at lower-income individuals, which describes most students. There’s also the newer Canada Carbon Rebate in applicable provinces and, as of July 2026, the new Canada Groceries and Essentials Benefit — all of which flow from having a return on file. A student who doesn’t file leaves this money unclaimed.

It banks tuition credits for the future. More on this next, because it’s substantial.

Tuition Credits: A Deferred Asset Worth Protecting

If the student is in post-secondary education, they’ll receive a T2202 (Tuition and Enrolment Certificate) from their institution — typically available through the student portal by the end of February. It reports eligible tuition and fees paid during the year.

The tuition tax credit is calculated at the lowest federal rate — 14% for 2026 — of eligible fees, plus a provincial credit where applicable. So $10,000 of tuition generates a federal credit of roughly $1,400, with provincial credits on top in most provinces (Ontario is a notable exception, having eliminated its provincial tuition credit).

Here’s the key insight: a student with little or no income can’t use much of this credit, because they have little or no tax to offset. But the credit isn’t lost. There are two options, and the choice matters:

Carry it forward. Unused tuition credits carry forward indefinitely, staying attached to the student until they have taxable income to apply them against — typically their first year or two of full-time work after graduation. For most students, this is the better long-term choice, because the credit ends up sheltering income that would otherwise be taxed at their new, higher earning level.

Transfer it. Alternatively, the student can transfer up to $5,000 of the current year’s federal tuition amount to a supporting parent, grandparent, or spouse, who claims it on their own return. This creates immediate tax savings at the family level, which is appealing if the parent is footing the tuition bill.

A few rules worth knowing. The student must always apply the credit to reduce their own tax to zero first; only the leftover current-year amount can be transferred. Only the current year’s tuition can be transferred — carry-forward balances from prior years can never be transferred, they can only be used by the student. And a transfer is permanent: once given to a parent, that amount can’t be reclaimed by the student later. My general guidance is that carrying forward is usually the stronger play unless the family genuinely needs the savings now, because the credit is typically worth more to the student down the road — but it’s a family conversation worth having deliberately rather than by default.

One historical note that still trips people up: the separate federal “education and textbook amounts” were eliminated back in 2017. Only actual tuition and eligible fees on the T2202 generate the credit now — not living costs, parking, or student association fees of a personal nature.

A Few Practical Pointers for Students

Keep every T4 and T2202. Employers must issue T4s for employment income, and you’ll need them (and any T2202) to file accurately. The CRA also receives copies, so leaving income off your return will eventually surface.

Consider filing even for years with no income at all. If you were a student with tuition but no job, filing still records your tuition carry-forward and keeps your benefit eligibility current.

Watch for scholarship and bursary income. For most full-time post-secondary students, scholarship, fellowship, and bursary income is fully exempt from tax under the scholarship exemption — but it should still be reported correctly on the return, and the rules differ for part-time students.

If self-employed — tutoring, freelance design, reselling, content creation — the rules change. That’s business income, with no tax withheld at source, and if it’s substantial it can carry its own filing and even CPP obligations. A student earning meaningful self-employment income should get advice rather than assume the rules are the same as a T4 job.

The Bottom Line

For most students, a summer job won’t generate an income tax bill — the basic personal amount of $16,452 for 2026 sees to that. But that’s precisely why filing matters more, not less. Filing recovers income tax that was over-withheld during the summer, builds RRSP room that compounds in value over a career, switches on tax-free benefit payments like the GST/HST credit once the student turns 19, and banks tuition credits worth real money down the road.

The habit is what counts. A student who files every year — even the zero-income years — is quietly building financial infrastructure that pays off for decades. It’s one of the best-value hours a young person can spend, and a genuinely worthwhile thing for parents to help set up.

If you or your child has questions about a first return, whether to transfer or carry forward tuition, or how self-employment income changes the picture, a short conversation with your CPA is a smart place to start.
