Boss Sent You a T4? Here’s What It Means

So, you’ve got your first job (yay paycheques 🎉), but then February hits and your boss drops a T4 slip in your inbox. 🤔 What even is this thing? Here’s the lowdown ⬇️


💡 What’s a T4?

A T4 slip = your yearly money scorecard 📊.

It’s officially called the Statement of Remuneration Paid, and it shows:

  • 💵 How much $$ you made (your total employment income)
  • 🏦 How much tax your boss already sent to CRA
  • 🧾 Other deductions like CPP (Canada Pension Plan) & EI (Employment Insurance)

Think of it as a summary of all your paystubs and what was sent to the government. It’s not a receipt—it’s more like your annual financial report card.


Who Gets a T4?

  1. Employees
    Anyone who worked for an employer and received employment income (salary, wages, commissions, bonuses, etc.) during the year.
  2. Part-Time & Seasonal Workers
    Even if you worked only a few weeks or earned a small amount, you should still receive a T4 if you were paid as an employee.
  3. Students & Interns
    If you were paid for your work (not just receiving academic credit), you’ll likely get a T4.
  4. Contract Employees (Sometimes)
    If you were treated as an employee (not self-employed), you’ll get a T4. But if you were paid as an independent contractor, you might receive a T4A or no slip at all—you’d report income using invoices and bank records.
  5. Anyone with Tax Deductions at Source
    If your employer deducted income tax, CPP, or EI, they must issue a T4.

Who Doesn’t Get a T4?

  • Self-employed individuals (you report income on your own)
  • Freelancers or gig workers paid without payroll deductions
  • Volunteers or unpaid interns

📅 When Do You Get It?

Employers must give you your T4 by the end of February every year.

👉 Example: Your 2025 T4 should show up by Feb 28, 2026.


⚠️What If I Do Not Receive A T4 From My Employer?

  1. Wait Until Early March
    Employers are legally required to issue T4 slips by February 28 (or the next business day). If you haven’t received it by the first week of March, it’s time to follow up.
  2. Check CRA My Account
    If your employer submitted the T4 to the CRA, you can access it online:
    • Sign in to CRA My Account
    • Look under “Tax Information Slips” for your T4
    • You can use this version to file your taxes
  3. Contact Your Employer
    Reach out to your employer or HR department. Confirm:
    • They filed your T4 with CRA
    • They have your correct mailing/email address
    • When they plan to send it
  4. Use Pay Stubs to Estimate
    If you still don’t get your T4, you can:
    • Use your final pay stub to estimate income and deductions
    • File your return with a note explaining the missing T4
    • CRA may request documents later, so keep everything
  5. Call CRA for Help
    If your employer is unresponsive, call CRA directly. They may:
    • Confirm if the T4 was filed
    • Provide box amounts over the phone
    • Help you file without the physical slip

🪧 Important Notes

  • Don’t skip filing just because you’re missing a T4.
  • Keep records of all communication with your employer.
  • Attach a note to your return if filing without a T4, explaining the situation.

⚠️What If There Is A Mistake In My T4?

  1. Review the Slip Carefully
    Compare your T4 with your final pay stub or payroll records. Common errors include:
    • Wrong income amount
    • Incorrect tax deductions
    • Mistakes in CPP or EI contributions
    • Incorrect Social Insurance Number (SIN)
  2. Contact Your Employer Immediately
    Your employer is responsible for issuing accurate T4 slips. If you spot an error:
    • Let them know what’s wrong
    • Ask for an amended T4 slip
    • They must mark it as “Amended” and send it to both you and the CRA
  3. Use the Corrected Slip to File
    If you receive the amended T4 before filing, use it to file your return.
    If you already filed your taxes, you’ll need to:
    • Wait for your Notice of Assessment (NOA)
    • Then file a T1 Adjustment Request (T1-ADJ) to update your return
  4. If Your Employer Won’t Fix It
    If your employer refuses or delays:
    • You can file a complaint with the CRA
    • CRA may investigate and request corrections if you provide enough evidence
    • File your return with a note explaining the incorrect T4

🪧 Important Notes

  • You can’t change the nature of income (e.g., from salary to dividends) once the T4 is filed.
  • Don’t ignore the error—even small mistakes can affect your refund or trigger CRA reviews.
  • Keep all records (emails, pay stubs, amended slips) in case CRA asks for proof.

🔑 Why Does It Matter?

You need your T4 to file taxes 📂. Without it, CRA can’t calculate your refund or balance.

It matters because:

  • 💸 You might get a refund (extra cash back)
  • 😬 Or you might owe money (less fun)
  • 🎁 It’s used for benefits like the GST/HST credit & other government $$

📊 What’s on a T4?

It looks complicated but it’s just boxes + numbers. Key ones:

  • Box 14 💵: Total income
  • Box 22 💳: Income tax deducted
  • Box 16 🏦: CPP contributions
  • Box 18 🛟: EI premiums

👀 Example

You worked part-time at Starbucks ☕ in 2024 & made $15,000.

Your T4 could show:

  • Box 14: $15,000 💵
  • Box 22: $1,000 💳 (tax withheld)
  • Box 16: $600 🏦 (CPP)
  • Box 18: $250 🛟 (EI)

When you file, CRA checks if you paid too much tax. If yes, you get some of that $1,000 back 👏.


Pro Tips

✅ Don’t lose it 📂 — keep a digital copy
✅ Taxes due April 30 🗓️
✅ Even if you made little $$, file anyway ➡️ you might receive a refund 🤑


🏁 Bottom Line

Your T4 = yearly money scorecard 📊.
It’s not scary—it’s how you make sure you get your refund 💸 and stay on the government’s good side 👌.

So when February hits and you see “T4,” don’t panic 🚫😅.
Just grab it, file it, and let future-you enjoy the $$$.
