Key Tax Filing Dates for Ontario Small Businesses

If you own a small business and pay salary or wages to staff or give a taxable benefit to another recipient, you must pay source deductions from the amount, which you are then obligated to remit to the Canada Revenue Agency (CRA). Filing before deadlines is not as easy as it sounds. However, with the help of our expert accountants, you don’t need to worry about dealing with this process on your own!

The source deductions that you must withhold and remit to the CRA include any combination of:

  • Canada Pension Plan (CPP) contributions;
  • employment insurance (EI) premiums; and
  • federal, provincial, or territorial income tax.

This means that as an employer, when you pay a salary to an employee, you will have to deduct CPP, EI and income tax. It is important to remit these source deductions on time to avoid any penalties or fines from the CRA (For more information, review the CRA website Failure to pay amounts deemed to be held in trust.)

The CPA4IT team helps small business owners file all required tax and source deduction reporting on time according to the CRA deadlines for source deductions below.
