When you first arrive in Canada as a student, your main focus is usually on finding a part-time job to help cover your rent and groceries. Once you finally land that job at a coffee shop, retail store, or warehouse, you start receiving your bi-weekly paycheques.
Fast forward to February or March of the following year, and you will start hearing everyone around campus stressing out about “Tax Season.” Suddenly, your employer hands you a piece of paper called a T4 slip. If you are new to the Canadian financial system, this document can look extremely confusing. What are all these boxes and numbers? Why is this single piece of paper so important?
Understanding your T4 slip is one of the most critical financial skills you must learn in Canada. Not only does it keep you legally compliant with the government, but it is also the key to unlocking thousands of dollars in tax refunds and government benefits. Here is your ultimate guide to understanding the T4 slip as an international student.
What Exactly is a T4 Slip?
In simple terms, a T4 slip is an official tax document created by your employer. Every time you get paid throughout the year, your employer automatically holds back a small portion of your money and sends it to the Canada Revenue Agency (CRA) on your behalf to cover your income tax, Employment Insurance (EI), and Canada Pension Plan (CPP).
At the end of the year, your employer must create a summary of exactly how much money they paid you and exactly how much money they sent to the government. This summary is your T4 slip. You use this document to file your annual tax return so the government can calculate if you paid too much tax (meaning you get a refund) or if you paid too little.
Decoding the Boxes on Your T4
When you look at your T4, you will see a bunch of numbered boxes. You do not need to be an accountant to understand them, but as a student, you should pay close attention to these two main boxes:
- Box 14: This is the total gross amount of money you earned from this job before any taxes or deductions were taken out.
- Box 22: This is the total amount of income tax your employer automatically took out of your paycheques over the entire year. As a part-time student with a lower income, you will often get a large portion of this money back as a refund!
Why Do International Students Need a T4 Slip?
Many newcomers think that because they are on a Study Permit, Canadian tax laws do not apply to them. This is a massive misconception. Here is why you absolutely need your T4 slip.
1. It is Required by Law
If you live in Canada for more than 183 days in a year and establish residential ties, the Canada Revenue Agency considers you a “Resident for Tax Purposes.” If you worked legally in Canada, you are legally required to report your income to the government by April 30th every year. Your T4 is the primary document you need to do this.
2. You Will Get Your Income Tax Back
Because international students are restricted in the number of hours they can work off-campus, your total yearly income is usually quite low. Canada has a “Basic Personal Amount.” If you earn less than this amount, you legally do not have to pay federal income tax. However, your employer probably still deducted tax from your paycheques throughout the year just to be safe. When you file your taxes using your T4, the Canada Revenue Agency will refund the income tax you paid.
3. It Unlocks Massive Government Benefits
Even if you did not pay any income tax, filing your taxes using your T4 registers you into the Canadian benefit system. Once you file, the government will automatically start sending you free money throughout the year to help with the cost of living. This includes the GST/HST Credit and the Carbon Tax Rebate.
If you throw your T4 in the garbage and never file your taxes, you are leaving hundreds of dollars of free government money on the table.
How and When Do You Get Your T4?
By Canadian law, your employer must provide your T4 slip on or before the last day of February following the calendar year you worked. For example, if you worked between January and December of 2025, your employer must give you your T4 by February 28, 2026.
You can get your T4 slip in a few ways:
- Digital Portal: Most major companies use payroll software. You can simply log into your employee portal and download the PDF.
- By Mail: Some smaller employers will physically mail the T4 to the address they have on file for you.
- CRA My Account: If your employer submitted the T4 to the government but forgot to send you a copy, you can usually log into your secure “CRA My Account” online and download a digital copy directly from the government.
What If You Have Multiple Jobs?
International students often change jobs or work two part-time jobs at the same time. You will receive one T4 slip from every single employer you worked for during the year. If you worked at a restaurant from January to June and then worked as a security guard from July to December, you must wait until you have both T4 slips before you file your taxes.
The Difference Between a T4 and a T2202 Slip
When tax season arrives, international students need to gather two very important documents. It is easy to get them confused:
- The T4 Slip: This comes from your employer. It shows how much money you earned from working.
- The T2202 Slip: This comes from your college or university. It shows how much money you paid in tuition fees.
You need both of these documents to file your taxes properly. The T2202 slip is incredibly valuable because your international student tuition fees give you “Tuition Tax Credits.” These credits can carry forward into the future to lower your tax bill when you graduate and get a high-paying full-time job.
Frequently Asked Questions (FAQs)
What if I was paid in cash and did not get a T4?
Working for cash “under the table” without paying taxes is illegal in Canada. If you work a cash job, you are participating in the underground economy. You will not get a T4, you cannot claim government benefits, and it cannot be used as official Canadian work experience.
Do I need to file taxes if I didn’t work this year?
Yes! Even if you arrived in Canada in October, focused entirely on your studies, and made $0 in income, you should still file a tax return. Filing a “zero income” return is the only way to tell the Canada Revenue Agency that you are alive and living in Canada, which triggers your eligibility for the GST/HST credit and Carbon Tax rebates.
What should I do if my employer refuses to give me a T4?
First, ask your manager politely. If they still refuse or ignore you by mid-March, you can calculate your income using your final pay stub of the year and file your taxes anyway. You can also call the Canada Revenue Agency directly; they will contact the employer on your behalf to enforce the law.
