When Are Taxes Due in Canada for 2026? Key Deadlines You Need to Know

Quick Summary of 2026 Tax Deadlines

For the 2025 tax year (filed in 2026), most individual Canadians must file and pay by April 30, 2026. If you or your spouse are self-employed, the filing deadline is June 15, 2026, though all taxes owed must still be paid by April 30, 2026 to avoid interest. Corporations generally must file within six months of their fiscal year-end, while payment is typically due within two to three months of that same date.

Navigating the Canadian tax landscape requires more than just circling a single date on your calendar. Between personal income tax, self-employment returns, corporate filings, and the evolving requirements for trusts, the “tax season” is actually a series of milestones.

Missing these dates results in a stern letter from the Canada Revenue Agency (CRA) and it triggers compound interest and penalties that can significantly erode your hard-earned capital. At Bateman MacKay LLP, we prioritize proactive planning. This guide provides a comprehensive breakdown of the 2026 tax deadlines (for the 2025 tax year) to ensure you stay compliant and keep more of your money where it belongs, in your business and your pocket.

2026 Personal Income Tax Deadlines (T1)

For the vast majority of Canadians, the T1 General Income Tax and Benefit Return is the primary focus of the spring.

• Filing Deadline: April 30, 2026
• Payment Deadline: April 30, 2026

Even if you cannot pay your balance in full, it is vital to file your return on time. The CRA’s late-filing penalty is triggered by the date the return is received, regardless of when the payment is made. By filing on time, you avoid the initial 5% penalty on the balance owing.

RRSP Contribution Deadline

To reduce your taxable income for the 2025 tax year, you must have made your Registered Retirement Savings Plan (RRSP) contributions by March 2, 2026 (since the traditional March 1 deadline falls on a Sunday).

Deadlines for Self-Employed Individuals and Sole Proprietors

Self-employed Canadians receive a “filing grace period,” but there is a catch that often catches business owners off guard regarding interest.

• Filing Deadline: June 15, 2026
• Payment Deadline: April 30, 2026

While you have until mid-June to submit your paperwork, the CRA begins charging interest on any unpaid balance starting May 1, 2026. If you expect to owe tax, it is best practice to estimate your balance and make a payment by the April deadline to avoid accruing interest at the current prescribed rates.

Corporate Tax Deadlines (T2)

Corporate tax deadlines are determined by the corporation’s fiscal year-end rather than the calendar year.

Example for a corporation with a December 31, 2025 year-end:

• Payment Due: March 31, 2026 (for CCPCs) or February 28, 2026 (for others).
• Return Due: June 30, 2026.

“Tax deadlines in Canada are not simply administrative dates on a calendar. Missing them can trigger penalties, interest, and unnecessary stress for business owners. At Bateman MacKay, our role is to help clients stay ahead of these obligations through proactive planning and clear communication so there are no surprises when filing season arrives.”

Trust and Partnership Deadlines

The landscape for trusts has shifted recently with expanded reporting requirements and the introduction of new rules for bare trusts. It is essential for trustees to be aware of these timelines:

• T3 Trust Returns: For trusts with a December 31 year-end, the deadline is March 31, 2026.
• T5013 Partnership Returns: Generally due March 31, 2026, for partnerships where all partners are individuals.

Penalties and Interest for Late Filing

The CRA is not lenient when it comes to late submissions, especially for repeat offenders.

Late-Filing Penalty

The basic penalty is 5% of your 2025 balance owing, plus 1% of your balance for each full month your return is late, to a maximum of 12 months.

Interest on Overdue Tax

As of early 2026, the CRA’s prescribed interest rate for overdue taxes is 7%, compounded daily. This rate is reviewed quarterly. While it has decreased slightly from the highs of 2024, it remains a significant cost for those who do not pay on time.

Frequently Asked Questions (FAQ)

1. What happens if a tax deadline falls on a weekend?

When a deadline falls on a Saturday, Sunday, or a public holiday recognized by the CRA, your return is considered on time if it is received or postmarked by the next business day. This is why the 2025 RRSP deadline moved to March 2, 2026.

2. Can I get an extension on my tax payment?

The CRA does not typically grant extensions for the payment of taxes. However, if you cannot pay in full, you can contact the CRA to discuss a Payment Arrangement. While this doesn’t stop interest from accruing, it can prevent more aggressive collection actions.

3. I have no income to report. Do I still need to file?

Even if you have no income, filing is often beneficial. It is the only way to claim certain credits, such as the GST/HST credit, the Canada Child Benefit, and to keep your RRSP contribution room updated.

4. What is the penalty for a “Repeated Failure to File”?

If the CRA charged you a late-filing penalty in any of the three previous years (2022, 2023, or 2024), the late-filing penalty for 2025 could double to 10% of your balance owing, plus 2% for each month late (up to 20 months).
