First Time Filing Taxes in Canada: A Step-by-Step Guide (2026)

Updated

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 3: Choose Your Tax Software

Software Cost Best For
Wealthsimple Tax Free Most Canadians, simple returns
TurboTax Free Free Simple T4 only returns
H&R Block Free Free Basic returns

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
