Self-Employed Individuals

If in 2025, you or your spouse or common-law partner were self-employed, you have until June 15, 2026, to file your income tax and benefit returns.

Payments – Corporations

Eligible small-CCPCs can make quarterly instead of monthly tax instalment payments.
For example:

  • If a corporation’s tax year begins on October 10, 2025, the first instalment payment is due by January 9, 2026
  • The following payments are due on April 9, 2026, July 9, 2026, and October 9, 2026

GST/HST

You have a December 31 fiscal year-end. Your net tax for the 2025 fiscal year was $4,000 and you expect your net tax for the 2025 fiscal year to be at least that much. You have to make installment payments throughout your 2025 fiscal year. Your instalment due dates are as follows:

Fiscal Quarter

  • January 1 – March 31
    Due Date: April 30
  • April 1 – June 30
    Due Date: July 31
  • July 1 – September 30
    Due Date: October 31
  • October 1 – December 31
    Due Date: January 31

For those who have a December 31st year end, file annually and reported an amount owing for 2025, it is important to note that you must pay the amount owed by April 30, 2026, but have until June 15, 2026, to file the return.

Underused Housing Tax (UHT)

If you’re an affected owner of residential property in Canada, you must file a separate Underused Housing Tax (UHT) return for each applicable calendar year in which you owned property, by April 30, 2026, to avoid penalties and interest.

Corporation Income Tax

Income tax is determined by the corporation’s tax year-end, rather than the calendar year.

Filing deadline

  • Corporations are required to file their T2 corporate income tax returns within six months of the end of each tax year

For example:

If your tax year ends March 31, your filing due date is September 30.
If your tax year ends August 31, your filing due date is February 28 (or Feb 29 in leap years).
If your tax year ends September 23, your filing due date is March 2 (2026).

Payment deadline

Corporations generally have to pay income tax in monthly or quarterly instalments.

  • Two or three months after the fiscal year ends.

For example:

If a corporation’s tax year begins on October 10, 2025, the first instalment payment is due by January 9, 2026.
The following payments are due on April 9, 2026, July 9, 2026, and October 9, 2026.

Trust Income Tax (T3)

All trusts, unless specific conditions are met, must file a T3 return for tax years ending after December 30, 2025.

Filing dates

In the same calendar year, you have to file the T3 return, the related T3 slips, NR4 slips, and T3 and NR4 summaries no later than 90 days after the trust’s tax year-end. You should also pay any balance owing no later than 90 days after that year-end.

Partnership income

Annual return

You need to file your yearly business return and give out T5013 forms to partners by a specific deadline. This deadline changes depending on the type of partners you have. You can send these forms by mail, in person, or online, but it must be done by the filing deadline.

Due dates

  • March 31 after the calendar year in which the fiscal period of the partnership ended if, throughout the fiscal period:
    • all partners are individuals, including end members of tiered partnership, and investment clubs that file on the modified-partnership basis. We consider a trust to be an individual.
  • Five months after the end of the partnership’s fiscal period if, throughout the fiscal period:
    • all partners are corporations, including end members of a tiered partnership.
  • In all other cases, the earlier of:
    • March 31 after the calendar year in which the fiscal period of the partnership ended
    • the day that is five months after the end of the partnership’s fiscal period

Doing taxes for someone who died

In Canada, handling taxes for someone who has passed away involves filing a final tax return, known as the “final return,” for the deceased. The deadlines for filing and making payments on the final return depend on the date of death and whether the deceased, their spouse, or common-law partner was running a business at the time of death.

If a person dies early in 2025, on or before the filing due date for their 2025 T1 Return, and they have not filed that return, the due date for filing that return and paying any balance owed is:

  • 6 months after the date of death, on the same calendar day as the date of death.

Any balance owed on the surviving spouse’s or common-law partner’s 2025 return must still be paid on or before April 30, 2026, to avoid interest charges.

 

The Filing Deadline For The Final Return

  • Six months after the date of death.

Payment Deadline For Taxes Owed

  • Six months after the date of death.

 

If The Deceased, Their Spouse, Or Common-Law Partner Was Running A Business At The Time Of Death:

  • The filing deadline for the final return (if the death occurred on or before December 15, 2025) is June 15, 2026 — six months after the date of death.

If you are a GST/HST registrant with a reporting period that begins in 2025, you must file your GST return electronically.

  • file monthly or quarterly and
  • were not previously required to file electronically and
  • are filing a GST/HST return for a filing period beginning on or after January 1, 2025, and before April 1, 2026.
