Like the tax deducted from your monthly or bi-weekly paycheque, the businesses have to pay corporate tax regularly. You could have a small or a large company, but you are obliged to pay the tax. If you work with an accounting firm, you can easily handle corporate tax returns without putting yourself through a lot of stress and anxiety. They will handle it all for you, and you can focus on your business operations.

Quarterly Tax Installments 

When your business meets all the requirements to qualify as a small Canadian Private Corporation (CCPC) and fulfills CRA’s terms and conditions, you can choose to pay the quarterly installment payments.

Now you must be eager to know about the due dates, right? Well, the dates are decided based on the business’s fiscal year.

For instance, suppose the fiscal year of your business ends on 31st December. Now the quarterly taxes would be due by these dates below:

  • 31st March.
  • 30th June.
  • 30th September.
  • 31st December.

You have to ensure that you meet the requirements of the CRA if your small CCPC wants to pay quarterly tax installments. These Requirements include:

  • The compliance history has to be perfect.
  • The CCPC has claimed a small business deduction for the current or previous year.
  • The taxable income of the corporations has to be $500,000 or less than that, and the taxable capital has to be $10 million or less.

Monthly Tax Installments

When the corporation doesn’t fulfill the requirements of the quarterly tax installments, then you’d need to pay the monthly tax installments by the end of the month.

In case the corporation doesn’t qualify for the quarterly installments during a tax year. You can also proceed with paying the installment for the current year. After that, you can start paying the monthly installments.

However, there are few exceptions as well.

  • If the corporation is new, they don’t have to pay the tax in installments in the first year.
  • If the tax payable in total is $3000 or less than that, then you don’t have to pay the installments.

In both the cases above, you are required to pay the tax bill before the due date when it’s the end of the tax year.


Now you are familiar with the corporate tax installments due date in Canada. If your business qualifies for the quarterly tax payments, you can go for it, or else you have to pay it at the end of the month. On the other hand, new businesses are not required to pay the tax installments for the first year.
