✅ Updated for the 2025 tax year (filed in 2026)
This guide reflects the latest rules, deadlines, and CRA updates.
Filing your taxes in Canada can feel confusing at first — especially when you see unfamiliar terms like T4, T5, or T1 General.
The good news is that once you understand the flow, everything becomes much easier.
This guide walks you through the entire process step by step, in plain language, so you can file your 2025 tax return confidently.
Do you actually need to file a tax return? #
In most cases, yes.
If you worked, earned income, invested, or want to receive government benefits, you should file a return. Even if you didn’t earn anything, filing helps you receive credits like the GST/HST benefit.
When is the deadline? #
For the 2025 tax year, here are the key dates:
| Deadline | What It Means |
|---|---|
| April 30, 2026 | File your tax return |
| April 30, 2026 | Pay any taxes owed |
| June 15, 2026 | Filing deadline for self-employed |
⚠️ Interest starts May 1, 2026 on unpaid taxes.
Before you start: what do you actually need? #
This is where many people feel stuck — not because it’s complicated, but because the document names aren’t familiar.
Instead of focusing on form names, think about your situation first — then match it to the document.
If you had a job #
You’ll receive a T4 slip from your employer.
This shows:
- Your total income
- Taxes already deducted
If you earned extra or side income #
You may receive a T4A, or you may need to report income yourself.
This applies to:
- Freelance work
- Contract jobs
- Side businesses
If you have investments #
Your bank or brokerage will provide tax slips such as:
- T5 → interest or dividends
- T3 → income from trusts or ETFs
- T5008 → stock transactions (buying/selling investments)
These are usually available in your online account.
If you’re a student #
You’ll receive a T2202 from your school.
This allows you to claim tuition credits, which reduce your taxes.
If you contributed to an RRSP #
You’ll get an RRSP contribution receipt from your bank.
This helps reduce your taxable income.

Other income you may need to report #
Some income doesn’t always come with a slip, but still needs to be reported:
- Rental income
- Foreign income
- Cryptocurrency transactions
Expenses you may be able to claim #
Certain expenses can reduce your taxes if you kept receipts, such as:
- Medical expenses
- Charitable donations
- Childcare
- Moving expenses
- Union or professional dues
Missing documents? #
Don’t worry.
Most tax slips can be downloaded directly from your CRA My Account, which is often the easiest way to make sure nothing is missing.
How the tax filing process actually works #
Once you have your documents, the process follows a simple structure.
First, you report all your income.
Then, you apply deductions to reduce your taxable income.
After that, you apply credits to reduce the tax you owe.
At the end, you either receive a refund or pay a balance.
That’s the entire system.
Choosing how to file #
Most people file online using tax software.
This is the fastest and easiest method, and refunds are often issued within about 8 business days.
If your situation is more complex, you might use a tax professional.
Paper filing is still possible, but it’s slower and less common.
What is the T1 General? #
The T1 General is the official name for your personal tax return in Canada.
Even if you use software, you are still completing a T1 — it’s just done automatically.

Reporting your income #
You’ll enter all sources of income, including:
- Employment income
- Self-employment income
- Investment income
- Capital gains
- Pension income
- Foreign income
The CRA already receives copies of many of your slips, so accuracy is important.
Reducing your taxes with deductions #
Deductions reduce your taxable income.
Common examples include RRSP contributions, childcare expenses, and moving costs.
Reducing your taxes further with credits #
Credits reduce the actual tax you owe.
Some apply to almost everyone, while others depend on your situation.
Some credits are even refundable, meaning you can receive money back.
Submitting your return #
Once everything is complete, you submit your return.
- Online → submitted instantly via NETFILE
- Paper → mailed to the CRA
After filing, you’ll receive a Notice of Assessment (NOA).
What happens after you file? #
Your NOA confirms:
- Your final tax result
- Your refund or balance owing
- Your RRSP and TFSA contribution room
Refunds are typically issued within 8 business days if you use direct deposit.
What if you owe money? #
You can pay using:
- Online banking
- CRA My Account
- Pre-authorized debit
Interest starts after April 30, so paying early helps avoid extra charges.
A simple example #
Imagine someone earning $52,000 from a job.
They enter their income from a T4, claim an RRSP contribution, add a few expenses, and submit their return online.
Depending on how much tax was already deducted, they either receive a refund or owe a small amount.
Common questions #
Do you need to file with no income?
Yes, to receive benefits.
What if you’re missing slips?
Download them from CRA My Account.
How long keep records?
At least 6 years.
Made a mistake?
Use ReFILE or adjust your return.
