What’s Due End of March?

• If your GST/HST Filing is annual, and based on the Calendar Year January to December, AND your business is a partnership or your business is incorporated, then your annual ​GST/HST Return​ is due to be filed and paid on or before March 31st.
• If your business is incorporated, and owed greater than $3k in corporate Income Tax for the previous fiscal year, then it is required to pay installments for next year on the last day of every month. March 31st is the due date for the ​March Corporate Tax Installment​.
• If required, partnerships (except those made up of corporations, or a combination of individuals, corporations, and trusts with different filing dates) must file a ​Partnership Information Return ​before this March 31st.
• ​​NR4's​ are issued by Canadian Payers who make payments to non-residents of Canada for income such as interest, dividends, rents, royalties, pensions, and acting services. These are due to be filed with CRA on March 31st.
• Though there are no other standard items due at the end of this month, be aware that if your Sales Tax filing is monthly, February's GST/HST filing and remittance is due on March 31st. If your Sales Tax quarterly filing is on a different schedule because of a corporate fiscal year end date that is not standard, the GST/HST for a quarter December to February would be due March 31st. Also, if your Corporate Fiscal Year End is September, your Corporate Tax Return is due 6 months after your Fiscal Year end (in March). If your Corporate Year End is January, the Income Tax Payable is payable 2 or 3 months after the Fiscal Year End; either due in March or in April, depending on your corporation. Check in with your accountant to find out more about your corporate tax due dates specific to your corporation. Find out more ​here​.

What due dates are coming up in April?

Now’s the time to prep your April Calendar! #BeThatBusiness that is organized! Here are some April due dates that might affect your business:

• April 3rd is Good Friday, and a Holiday in most provinces. To find out the ins and outs of the Easter Weekend Payroll Legislation by province, check out this great ​post ​about the Easter Holiday from Paytrack.
• If you have employees, April 15th is the due date for your payroll source deductions if you are a regular remitter relating to March's payroll.
• If you are in Newfoundland & Labrador, and are a provincial government employee, then for you, the Monday closest to St. George's Day on April 23rd is a ​holiday for you​! This year, that's April 20th.
• If you have employees, then you likely are registered for provincial Workplace Insurance (WSIB/WCB). WCB in some provinces is due monthly, and on the 15th. In Ontario, ​WSIB is due quarterly for Insurable Earnings over $20k​, and the premiums on earnings from Jan 1st to March 31st are due on April 30th.
• If your GST/HST is quarterly, and falls on the standard quarters, then the 1st quarter (Jan to Mar), is ​due to be filed and paid​ on or before April 30th
• If your ​GST/HST Filing is annual​, and based on the Calendar Year January to December, AND you are a self-employed, then your due date to file your HST is June 15th. BUT! Your due date to PAY is April 30th.
• If your GST/HST is annual, and is based on the standard Calendar Year, and also was payable by more than $3k the previous year you filed, then you are required to pay a ​GST/HST installment​ towards your 2026 GST/HST Return on or before April 30th. This installment should be either 25% of what your net GST/HST was from your previous filing, or 25% of what you predict it will be if you predict it to be less then the year before.
• For those who are not self-employed (or are not a spouse of someone self-employed), their ​Personal Income Tax Return​ is due on or before April 30th. April 30th is also their due date to pay any income tax owing. ​
• For those who ARE self-employed (or are the spouse of someone self-employed), though their Personal Income Tax Return is not due until June 15th,​ your due date to pay any income tax owing is STILL April 30th!​ Even if your income tax is not finalized, find out an estimate of what the taxes may be, and be sure to pay that to CRA as an installment on 2025's tax account before April 30th.
• If you are incorporated, and you owed 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. April 30th is the due date for the ​April Corporate Tax Installment​.
• Though there are no other standard items due at the end of this month, be aware that if your Sales Tax filing is monthly, March's GST/HST filing and remittance is due on April 30th. Also, if your Corporate Fiscal Year End is October, your Corporate Tax Return is due 6 months after your Fiscal Year end (in April). If your Corporate Year End is February, the Income Tax Payable is payable 2 or 3 months after the Fiscal Year End; either due in April or in May, depending on your corporation. Check in with your accountant to find out more about your corporate tax due dates specific to your corporation. Find out more ​here​.
