Is a graduate student stipend taxable in Canada?

It depends on the source and structure of the stipend. If your stipend comes from an employer-employee relationship (e.g., you are employed as a research assistant or teaching assistant with a formal employment contract and pay stubs), you receive a T4 and the income is fully taxable employment income subject to CPP and EI deductions. If your stipend is a scholarship, bursary, or fellowship received from your university with no employment relationship, you receive a T4A and the income is technically "scholarship income" — which for a full-time student enrolled in a program lasting 3+ consecutive weeks is generally exempt from income tax under Section 56(1)(n) of the Income Tax Act. In practice, most grad students receive both a T4 (TA employment) and a T4A (scholarship/bursary component), and only the T4 amount is typically taxed.

What is the difference between a T4 and T4A for graduate students?

A T4 (Statement of Remuneration Paid) is issued by your university for income you earned as an employee — typically as a teaching assistant (TA) or research assistant (RA) where you have an employment contract and CPP/EI are deducted. This income is fully taxable employment income. A T4A (Statement of Pension, Retirement, Annuity and Other Income) is issued for scholarship, bursary, or fellowship income — typically shown in Box 105 of the T4A. For full-time students in a qualifying educational program, the scholarship exemption under Section 56(3) of the ITA makes this income fully exempt from tax. Enter the T4A Box 105 amount on Line 13010 of your T1 return; the scholarship exemption is automatically applied.

How is SSHRC, NSERC, or CIHR funding taxed?

Tri-council awards (SSHRC Doctoral Award, NSERC CGS, CIHR Fellowship, etc.) are reported on a T4A in Box 105 as scholarship/fellowship income. For a full-time graduate student enrolled in a program lasting 3+ consecutive weeks, the scholarship exemption under Section 56(3) of the ITA makes the entire amount non-taxable. You report the income on your T1 (Line 13010) and the exemption zeros it out — resulting in $0 taxable from the award. Important: this exemption applies only while you are enrolled full-time in a qualifying program. If you take a leave of absence or are not enrolled for part of the year, the calculation is pro-rated. Even though the income is non-taxable, you still file a T1 return to claim all other available credits.

Does a tuition waiver reduce the T2202 amount I can claim?

No — a tuition waiver does not reduce your T2202 amount or your eligibility for the tuition tax credit. The T2202 is issued by your university showing the full tuition fee, regardless of whether you received a waiver. If your university provides a tuition waiver reducing your out-of-pocket cost to zero or near-zero, you still receive a T2202 showing the full tuition amount, and you can still claim the full tuition credit. This is one of the most valuable — and most commonly misunderstood — benefits of a grad school package: you get the tax credit without paying the full tuition out of pocket. The tuition credit can be carried forward to high-income years after graduation.

Do graduate students build RRSP contribution room?

Yes, but only from employment income (T4), not from scholarship income (T4A). RRSP contribution room is generated at 18% of your previous year's earned income. For the RRSP formula, earned income includes employment income (TA/RA T4), self-employment income, and rental income — but NOT scholarships, bursaries, or fellowships. If your grad stipend package is $32,000 total, broken down as $15,000 TA employment (T4) and $17,000 scholarship (T4A): your RRSP room for the following year = 18% × $15,000 = $2,700. If you negotiate more of your stipend as employment income, you generate more RRSP room. This generally does not change your tax situation much during grad school, but matters for the cumulative room you will have available when your income rises post-graduation.

What happens to student loans while I am in graduate school?

If you return to full-time graduate study after an undergraduate degree and had an OSAP or Canada Student Loan, your loan re-enters the non-repayment period automatically when you register as a full-time student at a designated institution. You do not need to make payments during grad school. Your federal loan does not accumulate interest (0% since 2023). When you finish your program, the 6-month non-repayment period begins again before payments are due. If you were already in repayment before starting grad school, any payments you made applied to principal and your repayment clock does not restart from zero — it pauses and resumes from where you left off when you re-enter grad school.

Can graduate students claim home office expenses?

Graduate student home office expenses: if you work as a TA and are required to work from home by your university employer, you may be eligible to claim home office expenses using Form T777 — but only if your employer provides a signed T2200 (Declaration of Conditions of Employment) confirming the home office requirement, a dedicated workspace is used exclusively for work (not a bedroom desk), and you are claiming employment expenses (not research expenses). In practice, many TA employees cannot get T2200 forms from their universities for the home office condition. Research-related expenses (lab supplies, computing equipment purchased personally for research) can sometimes be claimed under academic research provisions — consult a tax professional familiar with Canadian graduate student situations.

Graduate Student Financial Guide Canada: Stipends, T4A Slips, SSHRC, and Taxes

Graduate student funding in Canada is a patchwork of T4 employment income, T4A scholarship income, tri-council awards, and tuition waivers — each with different tax treatment. Understanding the distinctions saves money and prevents errors on your T1 return.

Overview: typical grad student funding package

Income source	Tax slip	Taxable?
TA employment income	T4	Yes — fully taxable employment income
RA employment income	T4	Yes — fully taxable employment income
University scholarship/bursary	T4A Box 105	No — scholarship exemption for full-time students
SSHRC/NSERC/CIHR tri-council award	T4A Box 105	No — scholarship exemption
External fellowship (non-government)	T4A Box 105 (usually)	Usually exempt if student enrolled full-time
Tuition waiver	None (benefit in kind)	Not taxable; does not reduce T2202
Conference travel reimbursement	Sometimes T4A Box 28	Potentially taxable — verify with university

TA and RA employment (T4 income)

Teaching assistants and research assistants who have employment contracts with their university are employees. Your university deducts:

Income tax at source (based on your TD1 declaration)
CPP contributions (5.95% above $3,500 basic exemption)
EI premiums (1.66% of insurable earnings)

Important for grad students on TD1 forms: Many grad students forget to update their TD1 when they start a TA position. Claim:

Basic personal amount ($15,705 federal)
Your tuition credit if you want it reflected in reduced withholding (or file and receive it as a refund)
Provincial amounts on the provincial TD1

CPP and EI on TA/RA income: You cannot opt out. However, unlike many students who pay EI premiums they will never collect on, RA/TA employees who are terminated or laid off (not voluntarily quitting) may qualify for EI benefits between academic years if they have accumulated 420+ insurable hours — this is a real benefit for some grad students.

Scholarship and fellowship income (T4A Box 105)

The scholarship exemption

Under Section 56(3) of the Income Tax Act, scholarship and bursary income received by a student enrolled full-time in a program lasting at least 3 consecutive weeks is fully exempt from income tax.

How to claim on your T1:

Enter the T4A Box 105 amount on Line 13010 (Scholarships, fellowships, bursaries, and study grants)
On the adjacent line, claim the scholarship exemption — your tax software does this automatically if you claim “full-time student” status
Result: the income on Line 13010 is offset by the exemption → zero taxable income from scholarships

What if you are doing a part-time graduate program? The scholarship exemption is reduced for part-time students. The amount eligible for the exemption is limited to tuition paid plus a fixed amount per registered term. If you are part-time (which is uncommon for funded grad students), consult CRA guides or a tax professional.

Tri-council awards: SSHRC, NSERC, CIHR

The three federal research councils award competitive graduate students:

Council	Key programs	Typical doctoral award
SSHRC	SSHRC Doctoral Fellowship, CGS-M, CGS-D	$50,000–$70,000/year (CGS-D)
NSERC	NSERC CGS-M, CGS-D, PGS D	$17,500–$35,000/year
CIHR	CIHR CGS-M, CGS-D, Fellowship	$50,000–$70,000/year

Tax treatment of tri-council awards: Reported on T4A Box 105. Apply the scholarship exemption on Line 13010. Result: the full award is non-taxable while you are enrolled full-time.

Does the non-taxable nature affect RRSP room? Yes — tri-council awards do NOT generate RRSP contribution room because they are scholarship income, not earned income. Only your TA/RA employment income generates RRSP room.

What if you win a tri-council award and previously held a T4 TA position? In many cases, holding a CGS or major fellowship means the university restructures your funding package. Some universities reduce TA employment to $0 and replace it entirely with scholarship. This is important: if your package moves from mostly-T4 to mostly-T4A, you generate less RRSP room for that year. Plan accordingly.

Tuition waivers and T2202

Graduate students at many Canadian universities receive partial or full tuition waivers as part of their funding package. This is a benefit in kind paid by the university directly to your tuition account.

Key facts:

The tuition waiver is not income you receive and is not reported on your T4 or T4A
Your T2202 still shows the full tuition amount regardless of waiver
You claim the full tuition credit against any tax you owe or to carry forward
A typical PhD student in Ontario with $8,000+ in annual tuition accumulates $1,200+ in federal tuition credits per year even if they pay nothing out of pocket

Example:

Tuition: $8,500/year
Waiver: 100% (you pay $0)
T2202 shows: $8,500
Federal tuition credit: 15% × $8,500 = $1,275
This credit offsets future income tax after graduation

Do not throw away or ignore your T2202 slips during grad school — they are worth real money in your first years of post-graduation employment.

Building RRSP room during graduate school

Income source	Generates RRSP room?
TA employment income (T4)	Yes — 18% of that year’s T4 income
RA employment income (T4)	Yes
SSHRC/NSERC/CIHR award (T4A)	No
University scholarship/bursary (T4A)	No
Tuition waiver	No

Example:

TA income (T4): $18,000/year
Scholarship income (T4A): $14,000/year
RRSP room for next year: 18% × $18,000 = $3,240
Total grad school RRSP room (4 years): ~$12,960

This room is available immediately but most grad students don’t contribute in school (income is low). The room carries forward indefinitely — you can contribute it in your first high-income post-graduation year, creating a significant tax deduction.

Filing your T1 as a graduate student

What to include:

All T4 slips (TA/RA employment income)
All T4A slips (Box 105 scholarship income — claim scholarship exemption)
T2202 from your institution (for tuition credit — carry forward or apply)
Statement of interest paid on government student loans (for Line 31900 if provincial loans still have interest)
Any other income sources

Commonly missed credits:

T2202 tuition credit (carry forward to post-graduation years)
CPP employee contribution credit (15% of Box 16 from T4)
EI premium credit (15% of Box 18 from T4)
GST/HST Credit (register at first filing — received quarterly if income is low)
Ontario Trillium Benefit (if Ontario resident with low income)
