Do summer students pay income tax in Canada?

They pay tax exactly the way every other employee does. The federal basic personal amount in 2026 is $16,452, which means most summer students earning less than that across the year will owe no federal income tax at year-end. But the employer is still required to withhold tax during the summer based on the CRA's pay-period tables and the student's TD1 form. If too much is withheld, the student claims it back as a refund when they file their return.

Do students under 18 pay CPP?

No. CPP contributions begin in the month after the employee turns 18. An employee who turns 18 on July 15, 2026, starts CPP contributions in the August pay period, not earlier. This is the only age-based exemption in the Canadian payroll system. The same rule applies for QPP in Quebec.

Yes, in almost all cases. There is no student-specific EI exemption and no general age exemption either. The narrow EI exemptions are tied to non-arm's-length employment (a student working for a parent or sibling in a family business may be in non-insurable employment), self-employment, and certain narrow categories like agricultural work paid by piece-rate. A student earning $14 an hour at a coffee shop pays EI on every dollar.

How does the TD1 form work for a summer student?

Every employee, including a summer student, completes a federal TD1 and a provincial TD1 (or TD1-QC in Quebec) on their first day. The student claims the federal basic personal amount of $16,452 on line 1 of the federal form, plus the equivalent on the provincial form. The employer uses the totals to look up the right tax-withholding amount in the CRA tables for each pay period. A student who has multiple jobs in the same year should claim the BPA on only one TD1 to avoid under-withholding across the two employers.

What about Quebec summer students?

Quebec students pay QPP instead of CPP, on the same age basis (contributions start the month after their 18th birthday). They also pay QPIP (Quebec parental insurance plan) regardless of age, on every dollar of insurable earnings up to the 2026 QPIP ceiling of $98,000. EI in Quebec is at the reduced rate of 1.31% (2026 estimate). The Quebec TD1-QC determines provincial tax withholding.

Does a summer student need a T4 at year-end?

Yes. Any employee paid $500 or more in a year, or for whom any CPP or EI contributions were withheld, must receive a T4 from the employer. Summer earnings flow onto the T4 the same way regular employment income does. The student then files their personal tax return by April 30 of the following year and reconciles any over-withholding back.

Are there any payroll deductions that genuinely don't apply to summer students?

The only meaningful one is CPP for employees under 18. Everything else (federal tax, provincial tax, EI, employer health tax where applicable, workers' compensation premiums) applies the same way it would for any other employee. The 'students are exempt' framing that circulates in some employer guides is incorrect; the truth is closer to 'most students earn under the BPA threshold and get their tax withholding refunded at year-end.'

Hiring Summer Students in Canada: TD1, CPP, EI, and What's Actually Exempt

The myth and the reality

Every Canadian small employer making a first summer hire encounters the same belief, usually delivered with confidence by a friend or a family member: students do not need to have tax, CPP, or EI deducted from their pay. The belief is wrong in three different ways, but the underlying intuition (students often end up with little or no net tax liability) is correct. The path from the wrong premise to the correct conclusion runs through some confusing tax-withholding mechanics that the CRA designed long before anyone hired a 16-year-old for the summer.

What follows is the 2026 reality, what an SMB employer is actually required to do when hiring a student between May and Labour Day, and where the genuine exemptions are.

Federal income tax: the TD1 and basic personal amount

A summer student, like any other employee, completes a federal TD1 and a provincial TD1 (or TD1-QC for Quebec) on or before their first day of work. The TD1 is the form the employer uses to determine how much federal and provincial income tax to withhold from each pay period.

For 2026, the federal basic personal amount (line 1 of the federal TD1) is $16,452. The provincial basic personal amount varies by province: Ontario's is $12,989, Alberta's is $21,895, British Columbia's is $13,216, and so on across the country. The TD1 totals at the bottom of each form translate into a claim code, which the CRA's payroll deductions tables (or the equivalent CRA calculator output) convert into a per-pay-period tax-withholding figure.

For a student earning $18 an hour, working 30 hours a week from mid-May to late August (roughly 15 weeks), gross summer wages will land near $8,100. That is well under the $16,452 federal BPA threshold and under most provincial thresholds. The student will almost certainly owe zero federal tax for the year, and probably zero provincial tax in most jurisdictions.

What complicates the picture is the structure of CRA withholding. The CRA's pay-period tables assume a uniform earnings pattern across the year, the employee earning at this rate in each pay period for the full year. For a summer student, that assumption is wildly wrong: the actual income pattern is concentrated in 15 weeks, with zero earnings in the surrounding 37. But the employer is required to withhold based on the tables, not based on guesses about what the student's annualised income will be.

The result, common across Canadian summer employment, is that some tax may be withheld during the summer that the student then claims back as a refund the following April. The withholding is correct given the tables; the refund is correct given the actual annual income. The student gets the money back; the system works as designed; the only loss is the time value of the withheld cash sitting at the CRA between July and the following May.

A student who knows they will earn under the BPA across the year can ask the employer to reduce withholding using CRA form T1213, which lets the CRA authorise reduced source deductions in advance. In practice almost no summer student does this. The refund route is easier.

CPP: the one real age-based exemption

The Canada Pension Plan Act contains one clean exemption that does apply to a meaningful slice of summer hires: contributions to CPP begin only in the month following the month in which the employee turns 18.

The legislative source is the Canada Pension Plan Act, paragraph 6(2)(a), which excludes from the definition of pensionable employment any month before the month in which the employee attains 18 years of age. An employee who is 17 for the entire summer pays no CPP. An employee who turns 18 on August 12, 2026, pays no CPP for May, June, July, or August, and starts contributing in September.

For the employer, this means the CPP calculation depends on the employee's age in each pay period. Payroll systems should pick this up automatically based on the employee's date of birth on file, but the most common error is treating a date of birth as a static "yes / no" CPP flag rather than a month-by-month determination. An employee whose 18th birthday falls in the middle of the summer flips on partway through.

The Quebec equivalent rule is identical in structure: QPP contributions begin in the month following the employee's 18th birthday. Quebec exercised its right under section 94A of the Constitution Act to administer its own pension plan rather than join the federal CPP, and the resulting Quebec Pension Plan, in force from 1966, was negotiated in parallel with the federal scheme and preserved most of its design elements, including the under-18 exemption. The contribution rates differ (QPP is 6.40% versus CPP's 5.95% in 2026), but the age threshold is the same.

There is no upper age exemption for CPP contributions until the employee elects, at age 65 or later, to stop contributing using CRA form CPT30. That is rarely relevant for the summer-student segment.

EI: nearly no exemption

Employment Insurance, unlike CPP, does not have a student or age-based exemption. A 16-year-old earning $14 an hour at a coffee shop pays EI on every dollar at the 2026 federal rate of 1.66% (1.31% in Quebec, where the lower rate reflects the existence of QPIP). The employer pays 1.4 times that amount on top.

The narrow EI exemptions are not student-related at all. They are structural categories defined in the Employment Insurance Act and the Employment Insurance Regulations:

Non-arm's-length employment. A student employed by a parent, sibling, or other related party in a way that does not approximate an arm's-length arrangement may be in non-insurable employment. The CRA applies a facts-and-circumstances test: would the same employment have been offered to a stranger on the same terms? If the answer is materially no, the employment is non-insurable, and no EI is withheld.
Self-employment. A student who is genuinely self-employed (running a lawn-care business, freelancing as a tutor) is not in insurable employment and does not pay EI from those earnings. They may pay EI on a side employment job at the same time.
Specific agricultural and fishing categories. Some piece-rate work in agriculture and fishing is partially exempt. The categories are narrow and rarely relevant to mainstream summer hiring.

For the typical summer student in retail, hospitality, or service work, none of these apply. EI is withheld at the standard rate.

The OECD provides a useful comparator here. The United Kingdom's National Insurance system, broadly analogous to Canada's CPP-plus-EI structure, exempts employees under 16 from National Insurance entirely and zeros out the employer-side rate for under-21s up to the upper secondary threshold, an explicit youth-rate adjustment on the employer side. Canada chose, in the design of the EI scheme in the 1940s and the CPP scheme in 1966, to use a simpler universal rule with no youth-rate adjustment on either the employee or employer side. The single under-18 CPP exemption acknowledged that pensionable employment before adulthood was unusual rather than worth designing a graduated rate around.

Quebec: QPP, QPIP, and the lower EI rate

Quebec summer students are governed by a parallel structure that differs from the rest of Canada in three measurable ways.

QPP. Quebec employees pay QPP instead of CPP. The 2026 employee rate is 6.40% on pensionable earnings above the $3,500 basic exemption and below the $74,600 YMPE, plus 4.00% on earnings between the YMPE and the $85,000 YAMPE. The age threshold is the same as CPP: contributions start the month after the employee's 18th birthday.

QPIP. Quebec's parental insurance plan applies to every employee regardless of age. The 2026 employee rate is 0.494% on insurable earnings up to the $98,000 QPIP ceiling. A 16-year-old Quebec student pays QPIP on every dollar of summer earnings; the employer matches at 0.692%.

Reduced EI. Because Quebec runs QPIP separately, Quebec employees pay a reduced federal EI rate. The 2026 employee rate is 1.31% (compared with 1.66% in the rest of Canada). The reduction reflects the fact that QPIP, not federal EI, funds parental and maternity benefits for Quebec workers.

The TD1-QC form replaces the provincial TD1 in Quebec and feeds the Quebec tax withholding tables maintained by Revenu Québec. The mechanics are similar to the rest-of-Canada TD1; the credit amounts differ.

A worked example: 17-year-old earns through her 18th birthday

A useful concrete case. Élise, who turns 18 on July 22, 2026, takes a summer job at a Mississauga garden centre at $16.50 an hour, working 32 hours a week starting May 19. Her gross pay is $528 per week.

For pay periods ending before July 22 (May 19 through July 20, a 9-week window), the deductions are:

Federal tax: based on TD1 BPA of $16,452. Per-pay-period table likely produces a few dollars per period or zero.
Provincial tax (Ontario): based on TD1-ON BPA of $12,989. Similar.
CPP: $0 (Élise is 17).
EI: $528 × 1.66% = $8.76 per pay period.

For the first pay period after she turns 18 (covering July 21 onward), CPP starts. The CPP contribution is calculated on her pensionable earnings less the prorated basic exemption: $528 minus $67.31 (the weekly share of the $3,500 annual exemption) = $460.69 pensionable, times 5.95% = $27.41 per week in employee CPP. The employer matches at the same rate.

Across her 15-week summer, Élise contributes EI on every week and CPP for about six weeks. Her gross summer income is roughly $7,920. Her net tax liability at year-end is almost certainly zero (well under the federal BPA), but she has paid into the EI system, six weeks of CPP, and any tax that was withheld will be refunded the following April when she files her T1.

What this means at year-end

Every summer student who earned $500 or more or had any CPP or EI deducted must receive a T4 slip from the employer, due by the last day of February of the following year. The T4 reports gross employment income, CPP withheld, EI withheld, and any income tax withheld. The student uses the T4 to file their personal return by April 30. Most summer students get a full refund of the tax withheld, retain the EI contributions on their record (relevant if they ever claim EI benefits later in life), and retain the CPP contributions on their record (relevant for their eventual retirement pension).

For the employer, the summer student appears on the regular T4 summary at the end of February the same way any other employee does. There is no separate filing process for student employees.

The student-specific pieces of the Canadian payroll system are remarkably small: one CPP age exemption, one TD1 mechanic that produces an end-of-year refund pattern. Everything else is the standard machinery applied as written. The popular mythology around "exempt" student employment is mostly the gap between what the system looks like at the pay-period level and what it produces at the year-end reconciliation.

The takeaway for summer hiring

For a Canadian SMB hiring its summer roster between May and Labour Day in 2026, the operational picture is:

Every student fills out a federal TD1 and provincial TD1 on day one.
Federal and provincial tax is withheld each pay period using the standard CRA tables.
CPP applies only from the month after the student's 18th birthday.
EI applies to every employee regardless of age, at the federal rate (or reduced Quebec rate).
T4s issue at year-end. The student reconciles any over-withholding through their personal return.

The myth, comforting but wrong, is that students sit outside the payroll system. The reality, less convenient but defensible, is that they sit inside it on the same terms as everyone else, with one narrow CPP exception and an end-of-year tax refund pattern that produces most of the "no tax owing" outcomes the myth was reaching for.

For the platform that handles all of this automatically (TD1 collection, age-based CPP gating, T4 production at year-end), see Hibiscus HR. The CRA and Revenu Québec rates for 2026 are pre-loaded; the age-based CPP rule fires automatically based on the date of birth on file.
