What’s Due End of October?

Here are some end of October due dates that may apply to your business;

  • If your GST/HST is quarterly, and falls on the standard quarters, then the third quarter (July to Sept), is due to be filed and paid on or before October 31st. If you are an annual filer, then your GST/HST Instalment is due on October 31st.
  • If you have employees, then you likely are registered for provincial Workplace Insurance (WSIB/WCB). The filing and remitting of WSIB/WCB is different from province to province. Some provinces are due monthly on the 15th. In Ontario WSIB is on a quarterly schedule, and the premium for the earnings paid to employees July to September are due to be filed and remitted on or before October 31st.
  • Is your business subject to any other quarterly remittances that are industry specific, such as Municipal Accommodations Tax? These may be due for the July to Sept Quarter.
  • If you are incorporated, and you owed greater than $3k in corporate Income Tax for your previous fiscal year, then you are required to pay installments for next year on the last day of every month. October 31st is the due date for the October Corporate Tax Instalment.
  • Though there are no other standard items due at the end of this month, be aware that if your Sales Tax filing is monthly, September's GST/HST filing and remittance is due on October 31st. Also, if your Corporate Fiscal Year End is April, your Corporate Tax Return is due 6 months after your Fiscal Year end (October 31st). If your Corporate Year End is August, the Income Tax Payable is payable 2 or 3 months after the Fiscal Year End; either due end of October or end of November, depending on your corporation. Check in with your accountant to find out more about your corporate tax due dates specific to your corporation.
