Filing taxes for the first time can feel overwhelming, but it is simpler than most people expect. This guide walks you through every step — what to gather, which software to use, and how to make sure you do not leave money on the table.
Why Filing Taxes Matters
Even if you earned very little, filing your tax return:
| Benefit | What You Unlock |
|---|---|
| GST/HST Credit | Up to $500/year tax-free |
| Climate Action Incentive | Up to $700+/year (most provinces) |
| RRSP contribution room | Accumulates each year you file |
| Canada Child Benefit | Up to $7,437/year per child under 6 |
| Student grants & loans | Many require a filed return |
| Future income-tested benefits | Based on filed income |
The CRA cannot issue you these benefits unless you file.
Step 1: Gather Your Documents
What You Will Need
| Document | What It Shows | Who Sends It |
|---|---|---|
| T4 slip | Employment income + tax withheld | Your employer (by end of February) |
| T4A slip | Other income (scholarships, freelance) | Payer |
| T5 slip | Interest and investment income | Your bank |
| T2202 | Tuition amounts | Your school |
| RRSP contribution receipt | RRSP contributions | Your financial institution |
| Social Insurance Number (SIN) | Your tax ID | Service Canada |
| Prior year return | Carry-forwards (if applicable) | Your records |
No T4 yet? Log into My CRA Account after late February — your employer’s submitted copies appear there.
First-Time Filer Checklist
- Gathered all T slips from employers, banks, schools
- Have your SIN ready
- Have your date of birth and address
- Collected receipts for any deductions (tuition, medical, moving, donations)
- Know which province you lived in on December 31 of the tax year
Step 2: Set Up Your CRA My Account
CRA My Account is your personal online portal with the CRA. Register before filing so you can:
- See your T slips directly
- Track your refund status
- Check RRSP and TFSA room
- Set up direct deposit for your refund
Register at canada.ca/my-cra-account. You will need your SIN, date of birth, and a code that the CRA mails to you.

Step 4: Enter Your Information
Most tax software uses an interview format — it asks you questions and fills in the forms automatically.
What You Will Enter
Personal Information
- Full name, SIN, date of birth
- Province of residence on December 31
- Marital status
Income
- Enter each T slip exactly as it reads
- Report all income, even from side jobs or tips
Deductions
- RRSP contributions
- Tuition (enter T2202 amounts)
- Moving expenses (if you moved for work or school)
- Union dues and professional fees
- Home office expenses (if working from home)
Credits You May Qualify For
| Credit | Who Qualifies |
|---|---|
| Basic Personal Amount | Everyone (~$15,705 federal) |
| Tuition Tax Credit | Post-secondary students |
| GST/HST Credit | Most Canadians under $50K |
| Canada Training Credit | Workers aged 25–65 |
| Disability Tax Credit | If you have a disability |
| Medical Expense Credit | If medical expenses > 3% of income |
Step 5: Review Before Submitting
Before you hit send, check:
- All T slips entered correctly (amounts match exactly)
- Correct province selected
- SIN matches your card
- Bank account info entered for direct deposit
- Review total tax owing or refund amount — does it seem reasonable?
Red flags: A very large refund (over $5,000) or a large balance owing suggests an entry error. Double-check your T4 amounts.
Step 6: File with NETFILE
NETFILE lets you submit your return directly to the CRA electronically. To NETFILE you need:
- A CRA-certified software (all options above qualify)
- Your SIN
- Your date of birth
- Your prior year income (for identity verification — if this is your very first return ever, you will submit a paper return instead)
First-ever return: The CRA cannot verify your identity electronically. Mail your first return to your tax centre by the deadline.
Second year onward: File online via NETFILE. Much faster — most refunds arrive in 2 weeks.
Common First-Time Filer Mistakes
| Mistake | Consequence | How to Avoid |
|---|---|---|
| Not filing at all | Miss out on benefits | File every year, even with no income |
| Missing T slips | Audits or penalties | Log into CRA My Account to confirm all slips |
| Wrong province | Under/over paying tax | Use your address on December 31 of the tax year |
| Not claiming tuition | Miss thousands in credits | Always enter your T2202 |
| Not setting up direct deposit | Wait weeks for cheque | Add bank info in software or CRA My Account |
| Forgetting to report TFSA room | Not a tax issue, but track it | Log into CRA My Account |
Understanding Your Notice of Assessment
After filing, the CRA sends a Notice of Assessment (NOA). This is your official tax result. It shows:
- Taxable income
- Taxes paid and owed
- Any balance owing or refund
- Your RRSP contribution room for next year
- Carry-forward amounts (tuition, capital losses)
Keep your NOA on file — you will need it next year.
What Happens After You File
| Timeline | What Happens |
|---|---|
| Day 0 | File via NETFILE |
| 2 weeks | Refund deposited (if direct deposit set up) |
| 4–8 weeks | Paper cheque (if no direct deposit) |
| 2–8 weeks | Notice of Assessment arrives |
| April 30 | Deadline for balance owing — interest starts after |
