How to File Taxes Canada: Step-by-Step Guide for 2025

NETFILE opens for 2024 returns: February 24, 2025 ·
Filing deadline (most individuals): April 30, 2025 ·
Self‑employed filing deadline: June 15, 2025 (payment due April 30)

Six key facts, one pattern: the CRA makes the same information available on multiple pages, so you can cross‑check deadlines and amounts with confidence.

Can I file tax by myself in Canada?

Yes, most Canadian residents with a Social Insurance Number can file on their own using CRA‑certified software. The two main electronic methods are NETFILE (you file directly) and EFILE (a preparer files for you). The CRA’s My Account portal lets you see past returns, get your notice of assessment, and even change a return online.

• Who can use NETFILE? Anyone with a SIN and a simple tax situation (T4, interest, tuition) can use approved software. The CRA lists all certified products on its site (CRA – certified software).
• Benefits of filing yourself vs. using a preparer You save money (many free software options exist) and learn the process. The trade‑off: you’re responsible for accuracy. The CRA says if you make a mistake, you can change your return online – processing takes about two weeks (CRA – change a return).
• Common mistakes first‑time self‑filers make Forgetting to include all T4 slips, missing the deadline, or overlooking refundable credits like the GST/HST credit. The CRA advises keeping copies of all documents in case they ask to see them (Scotiabank – keep copies).

The implication: if your taxes are straightforward (T4, a bit of interest), self‑filing is a fast, low‑cost choice. If you have rental income, business expenses, or assets, a professional preparer may save you headaches.

Do I have to file taxes if I made less than $10,000 in Canada?

Not necessarily – but you often should. The basic personal amount for 2024 is $15,705. If your total income is below that, you generally don’t have to file. However, if you had tax withheld from a paycheque or are eligible for refundable credits (GST/HST credit, Canada Child Benefit, Canada Workers Benefit), filing ensures you get that money back.

• Basic personal amount and when you still should file The basic personal amount is the income level at which federal tax starts. In 2024 it’s $15,705. But even if you earned less, filing can unlock benefits – the CRA won’t send you the GST credit unless you file (Canada.ca – refundable credits).
• Refundable credits you might miss The GST/HST credit, Canada Child Benefit, and Canada Workers Benefit all require a tax return. If you don’t file, you forfeit payments you may be entitled to.
• Self‑employed or investment income exceptions Self‑employment income over $3,500 requires filing regardless of total income. Similarly, if you have capital gains or certain investment income, you may need to file even if your total is below the threshold.

The trade‑off: filing a return that shows you owe nothing costs you only an hour or two, but the potential benefits can exceed $1,000. For most people earning under $15,705, filing is a net gain.

Who’s Required to File Taxes in Canada?

Canadian residents must file if they owe tax, received a demand from CRA, had capital gains, or if a repayment of benefits is required. Non‑residents with Canadian‑source income (rent, dividends, part‑time work) usually need to file as well.

• Residents vs. non‑residents Residents file a full T1 return on worldwide income. Non‑residents file only on Canadian‑source income. The CRA provides clear guidance on residency status (CRA – residency guidelines).
• Students, seniors, and new immigrants Students with scholarships or bursaries may need to file if the amount exceeds the education amount. Seniors receiving OAS and CPP have filing obligations if their income is above the threshold. New immigrants file from the date they become a resident.
• Special cases A deceased person’s legal representative must file a final return. Bankrupt individuals file for the period before bankruptcy. Trusts and estates have their own rules.

The pattern: the CRA’s rule is less about a number and more about whether you’ve already paid too much or too little. If you’re owed a refund, you want to file. If you owe, you have to file.

How much income tax will I pay on $70,000?

On $70,000 of taxable income in 2024, a resident of Ontario would pay approximately $14,700 before any credits. That breaks down to roughly $10,200 in federal tax and $4,500 in provincial tax. The exact amount depends on your province, deductions (RRSP contributions, union dues) and credits (basic personal amount, tuition, etc.).

Use the CRA’s payroll deductions calculator for precise numbers (CRA – payroll calculator). The key takeaway: your effective tax rate on $70k is about 21%, but RRSP contributions can drop it significantly. For more on future tax bracket adjustments, see CRA 2026 Tax Bracket Changes.

When can I start filing taxes for 2025 Canada?

For the 2024 tax year, NETFILE opened on February 24, 2025. For the 2025 tax year, the earliest day to file online is expected to be February 23, 2026, and the filing deadline will be April 30, 2026 (Canada.ca – 2025 tax season).

• CRA’s filing window NETFILE typically opens in late February. Mark your calendar for the third or fourth week of February.
• Deadline for 2024 returns April 30, 2025 – this is a firm date for most people. If you owe, pay by then to avoid interest.
• Self‑employed deadline You have until June 15, 2025 to file, but any balance owing must be paid by April 30. Penalties and interest start accruing on May 1 if you haven’t paid.
• Refund timing Filing online with direct deposit typically gets you your refund in 2 weeks. Paper returns can take 8 weeks or more.

The trade‑off: filing early gives you a faster refund and more time to fix mistakes. Waiting until the last week of April risks penalties if you run into problems.

How to File Your Taxes Online Step by Step

The CRA recommends using certified tax preparation software or a web application through its secure NETFILE service. Here’s a step‑by‑step walkthrough for first‑time filers.

1. Gather your documents Collect all T4 slips (employment), T5 (investment), RRSP receipts, tuition forms (T2202), and any other income or deduction slips (Canada.ca – gather documents).
2. Choose your software Pick a CRA‑certified NETFILE product. Many are free for simple returns (e.g., Wealthsimple Tax, TurboTax Free, StudioTax). Compare features on the CRA’s certified list (CRA – certified software).
3. Enter your information Follow the software’s prompts to input your personal details, income, deductions, and credits. The software will calculate your tax automatically.
4. Review and submit Double‑check all figures. The software will generate a tax return file. Submit it to the CRA through NETFILE (the software handles the transmission).
5. Confirm receipt You’ll receive a confirmation number. Keep this for your records. You can view the return in your CRA My Account within 24 hours.

For first‑time filers, the CRA also offers SimpleFile by phone – a short interview that determines if you need to file and automatically prepares a return for you. For information on maximum CPP amounts, see Maximum CPP Benefit 2025.
