What You Need to Know for the 2026 Tax-Filing Season
Tax season is just around the corner, and if you’re like most Canadians, you probably have questions about what’s changed and what you need to do. The good news is that understanding the basics of the 2026 tax-filing season doesn’t have to be complicated. Whether you’re an employee, a business owner, or self-employed, knowing the key dates and what’s new can help you avoid costly mistakes and ensure you don’t miss important deadlines.
Let’s walk through everything you need to know to navigate this year’s tax season smoothly.
Important Dates for the 2026 Tax-Filing Season
Missing a tax deadline can cost you money in penalties and interest charges. Here are the critical dates you need to mark on your calendar:
February 23, 2026 – Online Filing Opens
This is the first day you can file your 2025 income tax and benefit return electronically. If you’re eager to file early (and get your refund faster), this is your green light.
However, before you rush to file, make sure you have all your tax slips. Most employers and financial institutions issue tax slips by the end of February. Filing without all your documents can lead to errors, which means delays, reassessments, or even missed deductions that could save you money.
If you haven’t received your tax slips by the end of March, contact the issuer directly to get copies.
April 30, 2026 – Deadline for Most Canadians
This is the big one. April 30, 2026, is the deadline for most individuals to file their 2025 tax return and pay any taxes owed.
Filing and paying on time is crucial. If you miss this deadline and owe money, the CRA will charge you late-filing penalties (usually 5% of your balance owing, plus 1% for each month you’re late) and daily compound interest on unpaid amounts.
June 15, 2026 – Deadline for Self-Employed Individuals
If you’re self-employed, you get a bit more time to file—until June 15, 2026. This extended deadline also applies if your spouse or common-law partner is self-employed, even if you’re not.
But here’s the catch: even though you have until June 15 to file, if you owe taxes, you still need to pay by April 30, 2026. If you don’t, the CRA will charge interest on the outstanding balance starting May 1.
For self-employed Canadians, calculating what you owe can be complicated. You need to account for business income, eligible expenses, GST/HST, CPP contributions, and more. This is where professional help becomes essential.
What’s New with CRA Digital Services in 2026
The CRA has rolled out several changes to its online services this year. While some are meant to improve security and convenience, they also add new layers of complexity—and new opportunities to make mistakes if you’re not careful.
Regaining Access to Your CRA Account
If you’ve been locked out of your CRA account because you forgot your password or security answers, there’s now a self-service option to regain access online. You can create a new credential without calling the CRA.
While this sounds convenient, it also means you need to manage your login credentials carefully. If you lose access during tax season, it can delay your filing and access to important documents.
Backup Multi-Factor Authentication (MFA) Required
Starting in February 2026, all CRA account users must have a backup multi-factor authentication option on file. This could be a passcode grid or a third-party authenticator app.
Multi-factor authentication (MFA) is an extra security step that requires you to verify your identity using a second method (like a code sent to your phone) in addition to your password. The backup option ensures you won’t get locked out if your primary method fails.
Setting this up correctly is important, but it can be confusing if you’re not tech-savvy. And if you get locked out during tax season, it creates unnecessary stress.
Changes to Authorizing Representatives
If you work with a tax professional, they need to use the CRA’s Represent a Client portal to request access to your account. You then need to approve their request through your My Account portal to give them instant access.
This process is designed to protect your information, but it also means there’s an extra step you need to complete before your accountant or bookkeeper can access your tax information. Missing this step can delay your tax preparation.
No More Paper Tax Slips by Phone
The CRA has eliminated the option to request paper copies of tax slips (like T4, T4A, and T5 slips) by phone. You now need to contact the issuer directly or access your slips online through My Account.
This digital-first approach can be challenging if you’re not comfortable navigating online portals or if you don’t have reliable internet access. It also means you need to be proactive about gathering your documents well before the filing deadline.
Digital-Only Notices of Assessment
Starting in February 2026, you can only view your notice of assessment (NOA) digitally through My Account after the CRA processes your return.
Your NOA is an important document—it confirms what you reported on your tax return, shows your refund or balance owing, and outlines your RRSP contribution limit for the next year. If you’re not checking your online account regularly, you might miss important information or fail to catch errors that need to be corrected.
NETFILE Access Code Now Easier to Find
If you’re filing electronically using tax software, you’ll need a NETFILE access code. This 8-character code (letters and numbers) is now easier to find in your CRA account under “My Account” and “Tax Returns.”
While this is a small improvement, it’s one more thing you need to manage when filing online.
Why Professional Tax Help Matters More Than Ever
With all these digital changes and complex rules, it’s easy to see why many Canadians feel overwhelmed during tax season. While the CRA promotes self-filing options and digital tools, there are real risks to going it alone:
- Missed deductions and credits: The Canadian tax system offers dozens of deductions and credits—many of which you might not even know exist. A professional tax preparer knows what to look for and can maximize your refund or minimize what you owe.
- Errors and omissions: Simple mistakes like entering the wrong number or forgetting to report income can trigger a CRA review or audit. Fixing errors after the fact is time-consuming and stressful.
- Penalties and interest: Filing late, missing payments, or making errors can result in costly penalties and interest charges that add up quickly.
- Complex situations: If you’re self-employed, own a business, have rental income, sold property, or have investment income, your tax situation is more complicated. Professional guidance ensures everything is reported correctly and you’re taking advantage of all eligible tax planning strategies.
- Audit protection: If the CRA questions your return, having a professional who prepared it means you have expert support to respond and resolve issues.

When does the 2026 tax-filing season start in Canada?
The 2026 tax-filing season officially begins on February 23, 2026, when you can start filing your 2025 income tax return online. However, it’s important to wait until you have all your tax slips (usually issued by the end of February) before filing to avoid errors.
What is the deadline for filing taxes in the 2026 tax-filing season?
For most Canadians, the deadline to file your 2025 tax return is April 30, 2026. Self-employed individuals and their spouses have until June 15, 2026, to file, but any taxes owed must still be paid by April 30 to avoid interest charges.
What happens if I miss the April 30 tax deadline?
If you miss the April 30 deadline and owe taxes, the CRA will charge late-filing penalties of 5% of your balance owing, plus 1% for each additional month you’re late. You’ll also be charged daily compound interest on any unpaid amounts starting May 1.
Should I file my own taxes or hire a professional for the 2026 tax season?
