How do I make an instalment payment for GST and QST in Quebec?

Are you familiar with instalments? These are partial tax payments that most businesses are required to make in monthly or quarterly intervals.

Income tax law requires companies to pay these instalments to ensure that they are not favoured over other taxpayers who have their taxes withheld at source.

Find out which businesses are required to pay GST and QST by instalments, as well as when and how they are required to do so.

Which businesses are required to pay GST and QST by instalments?

Not all businesses are required to pay their taxes in instalments. It is important to be aware of the different taxation rules to understand the obligations your business must meet.

Businesses subject to instalment payments in the GST system are those with a total tax and capital tax liability of more than $3,000 each. This is without taking into account the financial institutions' compensatory tax. This rule also applies to the QST system.

Corporations with a tax balance of less than $3,000 at the federal level and less than $3,000 at the provincial level for the previous or current year are not required to pay tax by instalments. The same applies to corporations that have just incorporated or are in their first year of operation.

Since the QST rate is higher than the GST rate (9.975% vs. 5%), you may have to make instalment payments under the QST system, even though you are not required to make them under the GST system.

How to calculate your instalments

There are 3 options to calculate instalments and accurately determine the amounts to be paid:

• The no-calculation option is best if your income, deductions and credits are more or less constant from one year to the next.
• The prior-year option is best if your current year's income, deductions and credits are very similar to the previous year, but significantly different from those of two years prior.
• The current-year option is best if your income, deductions and credits in 2021 are significantly different from year to year.

You can calculate these amounts using form VDZ-458.0.2-V for QST and form FPZ-558.C-V for GST and QST.

When do I have to pay taxes by instalments?

For GST and QST, businesses eligible for instalment payments must make 4 instalments per year if their business tax reporting period is annual and 12 if it is monthly.

These payments are due no later than one month after the last day of each quarter of your fiscal year. At the end of the year, the return to be completed allows you to compare the total of the instalments calculated with the net total of the GST and QST that you must actually pay.

Corporate taxation in Quebec can be very complex. When determining the amount to be paid in instalments, it is best to consult a corporate tax specialist.
