Personal income tax returns, except for those of individuals with self-employment income, are normally due by April 30th, as is any amount owing. This applies to residents and non-residents. Penalties and interest may be charged for late returns or late payments.
Individuals with self-employment income and their spouses have until Monday, June 15, 2026 to file their 2025 personal tax returns, but any amounts owing must still be paid by April 30th. The June 15th date also applies for individuals who have both employment and self-employment income.
This extension applies to individuals who carried on a business in the year, other than a business whose expenditures are primarily the cost or capital cost of tax shelter investments. The extension also applies to the spouse of an individual who carried on a business in the year. S. 150(1)(d)(ii) of the Income Tax Act regarding the extension for individuals who carried on a business does not indicate that the individual must be exclusively self-employed (i.e., no employment income) to get the extension.
Tax Tip: Always file your tax return on time, or better yet, early!
If you are filing online, Canada Revenue Agency (CRA) sometimes allows a grace period for taxpayers who may experience delays in submitting their return online. Any amount owing is still expected to be paid by April 30th to avoid any penalties. See the CRA home page for more information, as they would post information here if they are allowing a grace period. You can NetFile your tax return online until long after the due date, but it will be considered late if filed after the due date.
Many CRA offices stay open until midnight on the personal income tax return filing due date to accept returns.
If you can't afford to pay, file your tax return on time to avoid late-filing penalties!
If you are unable to meet your tax obligations due to extraordinary circumstances (such as flooding), actions of the CRA, financial hardship or other circumstances, you may be able to apply for Taxpayer Relief.
The Income Tax Act specifies the due dates above as April 30th and June 15th. The Interpretation Act s. 26 indicates that when the due date falls on a holiday, then the due date will be considered to be the next day that is not a holiday. The Interpretation Act s. 35(1) defines "holiday" by listing the applicable statutory holidays, and indicates that Sunday is considered a holiday. According to the Interpretation Act, Saturday is not considered a holiday. However, the CRA information on Important Dates for Individuals indicates that "When a due date falls on a Saturday, a Sunday, or a public holiday, we consider your payment to be paid on time or your return to be filed on time, if we receive it or if it is postmarked on the next business day." Note that this is not true of the remittance of an amount deducted or withheld (such as payroll or GST/HST remittances), or payable by a corporation. Payments of these amounts are deemed to have been made on the date that they are received by CRA (Receiver General), as per s. 248(7) of the Income Tax Act.
