Individual and business taxpayers should be aware of these primary tax filing due dates:
April 30th — This is the deadline for filing most tax returns. If you owe anything, you must pay any balance by this date or interest will accrue. For 2016 tax returns, the filing deadline is May 1, 2017 as April 30th falls on a weekend.
June 15th — This is the deadline for self-employed individuals. If you, your spouse, or common-law partner conducted business during 2016, then you must file your 2016 tax return before this date (unless the business has expenditures that are primarily in connection with a tax shelter). However, it is necessary that you pay any balance due for tax year 2016 on or before April 30th.
For businesses, there are additional tax deadlines—as given in the explanations below.
HST (sales tax deadline)
The personalized GST/HST return (Form GST34-2) will show the due date at the top of the form. The due date of your return is determined by your reporting period. The CRA may charge penalties and interest on any returns or amounts that they do not receive by the due date.
A corporation must file a T2 income tax return if it resides in Canada, has done business in Canada, has a taxable capital gain, or sold taxable Canadian property—even if no tax is payable.
The due date to file a corporate income tax return is 6 months after the end of your corporate fiscal year-end. If, for example, a corporation has a December 31 year-end, then the return is due on June 30. For a fiscal year-end of March 31, the return is due September 30.
Trust Tax Returns
The due date for filing the T3 return varies according to the fiscal year-end for the particular type of trust.
It’s necessary to file the T3 return, along with the corresponding T3 slips, NR4 slips, and T3 and NR4 summaries no later than 90 days after the fiscal year-end for the trust. Any balance that you owe is due for payment no later than 90 days after the tax year-end for the trust. Read the CRA page on T3 filings for more details.
If necessary, we encourage you to review additional information on the fiscal periods for various types of trusts.
