  • RRSPs mature by December 31 of the year that you turn age 71. On or before that date, funds need to be withdrawn, transferred into a RRIF, or used to purchase an annuity.
  • Payroll:
    • Payroll remittances are generally due by the 15th day of the following month.
      • There are exceptions for small employers and for large employers. Contact us for more information.
  • GST:
    • GST returns and remittances are due as follows:
      • For monthly filers, your return and remittance are due by the end of the next month.
      • For quarterly filers, your return and remittance are due one month after the end of the quarter.
      • For annual filers:
        • Self-employed individuals, your remittance is due April 30th, and your return is due June 15th.
        • Corporations, partnerships, etc., your return and remittance are due three months after your fiscal year end.
        • Note: Annual filers generally are required to make quarterly installments if your net tax for the previous year was $3,000 or more. Installments are due one month after the end of the quarter.
  • PST:
    • B.C. PST returns and remittances are due monthly by the end of the next month.
  • Income taxes:
    • If your corporation is required to make income tax installments, they are generally due monthly on the last day of each month.
      • Some eligible small business corporations can make quarterly installments. Contact us to discuss.
      • If you are a self-employed individual, see the “Individuals” tab for installment due dates.
    • The balance of your corporation’s taxes owing are generally due two months after the end of the fiscal year. (For example, for a fiscal year ending August 31, taxes owing are due by October 31.)
      • However, for private companies with active business income and meeting certain criteria, including that the prior year’s taxable income was less than the small business limit, the balance of taxes owing are due three months after the end of the fiscal year. (For example, for a fiscal year ending August 31, taxes owing are due by November 30.)
    • Your corporation’s income tax return is due six months after the end of the fiscal year. (For example, for a fiscal year ending August 31, the return is due by February 28 of the following year.)
  • Information slips:
    • The due dates for various information slips are:
      • T4s for employee wages – the last day of February of the following year.
      • T4As for self-employed commissions or fees for services, death benefits, etc. – the last day of February of the following year.
      • T5s for dividends or interest paid – the last day of February of the following year.
      • T5018s for payments to subcontractors if your primary source of business income is from construction activities – six months after your choice of the end of the calendar year or the end of your company’s fiscal year.
  • Fiscal year end:
    • Generally all estates or trusts are required to use the calendar year as their taxation year.
    • A graduated rate estate (“GRE”) is an exception. For three years after an individual’s date of death, the GRE is allowed to have a fiscal year other than the calendar year. (Commonly, the anniversary of the date of death is used for the fiscal year end.) After three years, a GRE is required to change to a calendar year.
  • Income tax and information returns:
    • T3 Trust Income Tax and Information Return (“T3 Return“) – due 90 days after fiscal year end (i.e., March 31, 2026 for December 31, 2025 year ends).
      • New filing requirement: Beginning with taxation years ending on December 31, 2023, T3 Returns, including Schedule 15 Beneficial Ownership Information of a Trust, are required for almost all Canadian trusts or estates. For 2023 and 2024, the Canada Revenue Agency announced that this filing requirement does not apply to an arrangement under which the trust can reasonably be considered to act as agent for all the beneficiaries under the trust with respect to all dealings with all of the trust’s property (commonly called a “bare trust”).
    • T3 Statement of Trust Income Allocations and Designations (“T3 Slip“) and T3SUM Summary of Trust Income Allocations and Designations (“T3 Summary“) – due 90 days after fiscal year end.
      • T3 Slip(s) and a T3 Summary are required for any year in which the estate or trust allocated income or capital gains to a beneficiary. They generally are filed with the T3 Return.

Resources for executors

Both the Federal and the British Columbia governments have web pages and check lists that give you guidance about what needs to be done and who needs to be notified when someone passes away.

Here are some particular points to note:

  • Notify Canada Revenue Agency by calling 1-800-959-8281. You will need the deceased’s social insurance number. Here is a link with more details.
  • If the deceased was receiving Canada Pension Plan (“CPP”) or Old Age Security (“OAS”) benefits, call 1-800-277-9914 to notify Service Canada. Here is a link with more details.
  • Within sixty days of the date of death, you should apply for the CPP death benefit. You can apply online or by mail using Form ISP-1200. Here is a link with more details.
  • You should compile a list of the deceased’s assets. As you do so, note which assets were held by the deceased alone and which were held jointly with other parties.
    • You should identify the fair market value of the deceased’s assets as of the date of death. For investment accounts, request this from the financial institution.
    • Depending on the nature and ownership of the assets, you may or may not have to have the deceased’s will probated. If you do not already have a legal professional, we can give a referral.
    • If there are assets held outside of Canada, be sure to contact us about possible other considerations.

Here are some key dates and tax considerations to keep in mind:

  • As already noted, within sixty days of the date of death, you should apply for the CPP death benefit.
  • The due date for the deceased’s Canadian income tax returns depends on the date of death.
    • If the date of death is in November or December, then the deceased’s final tax return is due 6 months after the date of death or, if the deceased was self-employed, the later of 6 months after the date of death and June 15th.
    • If the date of death is before April 30th (or, if self-employed, before June 15th) and the prior year’s tax return has not been filed, the prior year’s tax return is due 6 months after the date of death or, if the deceased was self-employed, the later of 6 months after the date of death and June 15th. And, the final tax return is due by the normal due date in the following year.
  • Deemed disposition: Generally, the Income Tax Act (Canada) deems the deceased to have sold his or her capital assets for fair market value immediately prior to death. The effect of this is to trigger capital gains (or losses) that will be included in the deceased’s final income tax return. For this reason, you should identify the fair market value of assets as of the date of death.
  • Depending on the nature of deceased’s assets and whether or not there are any beneficiaries other than a spouse, a Form T3 Trust Income Tax and information Return may be required for the deceased’s estate. This return, if needed, is generally not due until ninety days after the first anniversary of the date of death.
  • There may be opportunities to minimize tax by making permitted elections or filing optional returns. Contact us to explore these possibilities.
  • After all required income tax returns are filed, the last step in the process related to income taxes is to file Form TX19 Asking For A Clearance Certificate. This ensures that all income tax obligations are met.
