Filing Your First Canadian Tax Return? Start Here.
Whether you just turned 18, arrived in Canada as a newcomer, or simply never filed before, your first tax return can feel overwhelming. It doesn’t have to be.
Here’s a straightforward guide to getting it done, even if you’ve never looked at a T4 in your life.
Do You Need to File?
You should file a Canadian tax return if any of the following apply:
- You owe tax for the year
- You want to receive the GST/HST credit, Canada Carbon Rebate, or Canada Child Benefit
- You had income tax withheld from your pay and want a refund
- You want to build RRSP contribution room for the future
Even if you earned very little or nothing, filing is often worth it because it unlocks government benefits and builds your tax history.
What You Need to Gather
Income slips
- T4: Employment income (from your employer)
- T4A: Scholarships, bursaries, or other income
- T5: Investment income (bank interest, dividends)
- T2202: Tuition amounts (from your school)
Most slips are available by late February in CRA My Account under “Auto-fill my return.”
Personal info
- Social Insurance Number (SIN)
- Date of birth
- Current address
- Direct deposit details (for faster refund)
How to File: 3 Options
Option 1: Free tax software (recommended)
CRA certifies several free tax programs each year. Popular choices include Wealthsimple Tax, TurboTax Free, and StudioTax. These walk you through each step and file electronically via NETFILE.
Option 2: Community volunteer tax clinic
If your income is modest, free tax clinics are available across Canada. Volunteers prepare and file your return at no charge. Check CRA’s website for locations near you.
Option 3: Hire a professional
If your situation is complex (self-employment, foreign income, rental properties), a tax professional can help ensure accuracy and maximize deductions.
Key Deadlines
- April 30: Filing deadline for most individuals. Also the deadline to pay any balance owing.
- June 15: Extended filing deadline for self-employed individuals (but any tax owing is still due April 30).
Common First-Timer Mistakes
- Not filing at all. Even with zero income, filing activates benefits like the GST/HST credit.
- Forgetting tuition credits. T2202 amounts can be carried forward or transferred to a parent.
- Skipping RRSP room. Filing builds RRSP contribution room even if you don’t contribute yet.
- Wrong SIN or address. Double-check before submitting. Errors delay processing.
What Happens After You File?
CRA processes electronic returns in about 2 weeks. You’ll receive a Notice of Assessment (NOA) confirming your return was accepted, your refund amount (if any), and your RRSP deduction limit for the following year.
Keep your NOA. You’ll need it for future reference.
The Bottom Line
Your first tax return is simpler than you think, especially with free software and CRA’s auto-fill feature. The hardest part is starting. Once you file that first return, every year after gets easier.
