A co-op placement is treated as employment for tax purposes. File a T1, claim all available credits, and take advantage of deductions most co-op students miss.
Your co-op placement: tax basics
When you complete a co-op term with a real employer:
- You receive a T4 slip in February after the year end
- Your income is employment income on Line 10100 of your T1 return
- Your employer withheld CPP, EI, and income tax during the placement
- You file this income exactly like any other employment income
When co-op income is NOT a T4: If your placement is an unpaid volunteer role or a school-funded bursary for unpaid work, you may receive a T4A instead (scholarship/other income). See the next section.
T4 from co-op: what each box means
| T4 Box | What it shows | Where it goes on T1 |
|---|---|---|
| Box 14 | Total employment income | Line 10100 |
| Box 22 | Income tax deducted | Line 43700 (tax already paid) |
| Box 24 | EI insurable earnings | Used to calculate EI premium on T1 Schedule 1 |
| Box 26 | CPP pensionable earnings | Used to calculate CPP contribution credit |
| Box 16 | Employee CPP contributions | Line 30800 (CPP credit) |
| Box 18 | Employee EI premiums | Line 31200 (EI credit) |
| Box 40 | Other taxable allowances and benefits | Added to income |
| Box 52 | Pension adjustment | Not directly tax — reduces RRSP room |
If your T4 shows only income and withholdings with no unusual boxes, your filing is straightforward: enter Box 14 as employment income, enter Box 22 as taxes already paid, enter CPP and EI amounts from their respective boxes.
CPP and EI on co-op placements
CPP contributions
Co-op students are subject to standard CPP rules:
| Detail | 2025 |
|---|---|
| Employee CPP rate | 5.95% |
| Basic exemption (annual) | $3,500 |
| Contribution on a $20,000 co-op income | 5.95% × ($20,000 – $3,500) = ~$982 |
You cannot opt out of CPP as a student employee. However, you can claim a 15% non-refundable federal credit on your CPP contributions (Line 31000) — on $982 in contributions, that’s a $147 tax credit.
EI premiums
| Detail | 2025 |
|---|---|
| Employee EI rate | 1.66% |
| On $20,000 co-op income | 1.66% × $20,000 = $332 |
You cannot opt out of EI. The $332 generates a small non-refundable credit at 15% = $50.
T2202 and co-op terms: the tuition credit interaction
At many universities with structured co-op programs, co-op semesters count as registered academic terms. If your university issues a T2202 covering co-op semesters, you can:
- Claim the T2202 credit on any co-op administration fees charged by the university (not the wage itself)
- Count co-op months as enrolled months for purposes of scholarship income exemption
Common at Waterloo, Guelph, McMaster, Queen’s, and others: The co-op office charges a co-op fees amount each work term. This appears on your T2202 as tuition paid. It generates a tuition credit (15% federal × those fees).
What is NOT eligible: Your wages/salary from the employer are not tuition and do not generate T2202 credit. Only amounts paid to the institution qualify.
Moving expense deduction for co-op
The moving expense deduction is one of the most underused benefits available to co-op students.
The 40-km rule (detailed)
You can deduct moving costs if you move for a co-op placement AND your new home is 40+ km closer to the employer than your old home.
How to measure 40 km:
- Measure from old home to new work location (by shortest usual route)
- Measure from new home to new work location
- If (old home to work) minus (new home to work) ≥ 40 km → you qualify
What you can deduct
| Expense type | Deductible? | Notes |
|---|---|---|
| Moving truck or van rental | Yes | Keep receipt |
| Gas for your own vehicle | Yes | Use CRA per-km rates or actual gas |
| Hotel during move | Yes | Up to 15 days of temporary lodging |
| Meals during move | Yes | Use simplified method: $23/meal, ≤ $69/day |
| Storage unit | Yes | While between homes during move |
| First/last month rent at new place | Partially | New place lease deposit — keep records |
| Lease-breaking fee at old place | Yes if applicable | Keep documentation |
| Real estate agent commission | Yes if applicable | Rarely relevant for students |
Cannot deduct: New furniture, renovations, personal clothing and items damaged in move, costs not directly related to the physical move.
How to claim moving expenses
- File Form T1-M (Moving Expenses Deduction) with your T1 return
- The deduction is claimed against income earned at the new location (your co-op income)
- If your deductible moving expenses exceed your income at the new location, you can carry forward the excess to the following year
Example:
- Moved 200 km for co-op placement earning $22,000
- Moving costs: U-Haul $350, gas $80, one night hotel $120 = $550 total
- Deduction: $550 off your co-op income
- Income for tax purposes: $22,000 – $550 = $21,450
Can you deduct work-from-home expenses on a remote co-op?
If you worked remotely for your co-op placement from a home office, you may be eligible for the employment expenses deduction under Form T777 — but only if:
- Your employer provides a signed Form T2200 (Declaration of Conditions of Employment) confirming you were required to work from home
- You use a dedicated space in your home exclusively for work (not your bedroom desk used for school too)
For most students on remote co-op placements, the T2200 is typically not issued for a 4-month term, making this difficult to claim. The simplified $2/day home office method was eliminated after 2022. Without a T2200, you cannot claim home office expenses.
What to do when you receive multiple T4s from co-op and school jobs
If you worked at a co-op placement AND had a part-time campus or off-campus job in the same year, you receive multiple T4s. File all of them:
- Enter each T4’s income, deductions, and withholdings separately in your tax software
- All income stacks on Lines 10100/10400 in total
- All withholdings apply toward your total tax payable
- If too much CPP was withheld across multiple employers (exceeding the annual maximum), you receive a refund of the excess via Line 44800 (CPP over-contribution)
OSAP impact of co-op income
| Co-op term timing | OSAP classification | Impact |
|---|---|---|
| Pre-study (summer before academic year) | Pre-study income | Reduces next-year OSAP in full above allowance |
| During-study co-op (formally enrolled) | In-study income | Partial reduction — less impact than pre-study |
| Post-study (after graduation) | N/A | Does not affect OSAP |
Students in alternating work/study programs (Waterloo, Guelph, etc.) who have formal work terms built into their academic program may have special OSAP rules for co-op income. Check with your institution’s financial aid office for program-specific rules.
