With the official launch of the 2026 filing season on February 23, 2026, Canadians must navigate new tax rate adjustments, enhanced digital security requirements, and updated benefit delivery systems.

Critical Tax Deadlines for the 2026 Filing Season
The CRA has confirmed the official timeline for filing 2025 income tax and benefit returns. Adhering to these dates is essential for maintaining eligibility for federal and provincial benefits.
- February 23, 2026: The CRA officially opened the NETFILE and EFILE services, allowing taxpayers to begin submitting their 2025 returns electronically.
- March 2, 2026: This is the final deadline to contribute to a Registered Retirement Savings Plan (RRSP), Pooled Registered Pension Plan (PRPP), or Specified Pension Plan (SPP) to reduce taxable income for the 2025 tax year.
- April 30, 2026: The general filing deadline for most individuals. This is also the final date to pay any balance owing for the 2025 tax year to avoid interest.
- June 15, 2026: The filing deadline for self-employed individuals and their spouses or common-law partners. However, any taxes owed must still be paid by April 30 to avoid compounding interest.
Major Legislative Changes and New Tax Credits
The 2025 taxation year, which Canadians are filing for in 2026, features a notable reduction in the lowest federal personal income tax rate.
Federal Income Tax Rate Reduction
Effective July 1, 2025, the lowest marginal tax rate was reduced from 15% to 14%. Because this change occurred mid-year, the effective rate for the full 2025 tax year is 14.5%. For the 2026 tax year and beyond, the rate will remain at 14%. To prevent this lower rate from reducing the value of non-refundable tax credits, the government has introduced a “top-up tax credit” for eligible filers, ensuring no taxpayer is negatively impacted by the rate change.
The Canada Groceries and Essentials Benefit
Filing a 2025 return is now the primary gateway to access the new Canada Groceries and Essentials Benefit (formerly the GST/HST credit). For 2026, an eligible family of four could receive up to $1,890. The CRA uses tax return data to automatically calculate eligibility, making timely filing crucial even for those with no income to report.
Elimination of the Underused Housing Tax (UHT)
As of the 2025 calendar year, the federal Underused Housing Tax has been eliminated. Taxpayers are no longer required to file UHT returns or make payments for 2025 or subsequent years. However, obligations and penalties for the 2022 through 2024 tax years remain in effect.
New Penalties and Interest Structures
The CRA has updated its enforcement mechanisms to encourage compliance, particularly regarding late filings and digital security.
Late-Filing Penalties
If you owe tax and do not file your return on time, the initial late-filing penalty is 5% of your 2025 balance owing, plus an additional 1% for each full month the return is late, up to a maximum of 12 months. For repeated failures to file, these penalties can double to 10% of the balance plus 2% per month.
Digital Security and MFA Requirements
Starting in February 2026, all CRA “My Account” users are required to have a backup multi-factor authentication (MFA) option on file. This includes a passcode grid or a third-party authenticator app. Failure to set up a backup may lead to account lockouts, potentially delaying the ability to track refunds or view Notices of Assessment.
How to Prepare Today: SimpleFile and Digital Tools
Preparation for the 2026 season focuses on automation and digital accuracy.
- SimpleFile Digital: Starting March 9, 2026, the CRA will expand access to SimpleFile Digital, a simplified filing service for individuals with lower incomes and straightforward tax situations. Even those who did not receive an invitation can now use an online questionnaire to check their eligibility.
- Direct Deposit: The CRA is prioritizing digital refunds. Taxpayers should verify their banking information in “My Account” to receive refunds and benefits up to five days faster than paper checks.
- Manage Balance Service: For those with existing tax debts over $1,000, the new “Manage Balance” tool in My Account allows users to schedule self-service payment arrangements without needing to speak to a collections officer.
