Are you in a situation where you need to register your business for GST/QST, but don’t know where to start? Some steps are essential to getting things right. In this guide, you’ll learn about the various benefits and eligibility criteria. You’ll also learn about the registration process and tax obligations.

The importance of registering your business for GST/QST

To begin with, anyone doing business in Quebec must register for the Goods and Services Tax (GST) and Quebec Sales Tax (QST). Once you’ve registered for GST, you’re also registered for Harmonized Sales Tax (HST). For accounting purposes, the GST rate is 5% and the QST is 9.975%, for a total of 14.975%.

Registering for GST/QST is essential if you make taxable rentals and supplies in Canada. However, you cannot register if you :

  • Are a personal trust
  • Are an individual or a partnership
  • Run a non-profit business
  • Offer tax-free products and services

To facilitate registration for various government programs and services, we recommend you obtain a Business Number (BN).

The benefits of registering your business for GST/QST

There are many advantages to registering your business with GST/QST files, including :

  • Claim taxes paid by your company
  • Increase your company’s credibility
  • Simplify management and customer relations

Here’s more information on each of them.

Claim taxes paid by your company

One of the main advantages of registering your company for GST/QST is that you can claim an input tax credit. This allows you to obtain a refund of the taxes you paid on purchases of goods or services for your business.

Increase your company's credibility

Charging and collecting GST and QST can help build your company’s credibility. In fact, being registered for GST/QST gives a clue as to your sales, generally in excess of $30,000. For some current or future customers, this can be significant. If your sales revenue is less than $30,000, you’re considered a small supplier, which relieves you of certain obligations such as collecting taxes.

Simplify management and customer relations

If your sales increase, you should think about registering your business for GST/QST. Because, if your business income exceeds $30,000, you’ll have to start billing and collecting taxes. Some of your customers may be unhappy, especially if this happens mid-year or during a fixed-term contract. The earlier you start charging GST and QST, the less of a surprise it will be for your customers… and the better your relationship will be with them.

Eligibility criteria for obtaining a GST/QST number

It’s important to be aware of the various eligibility criteria before registering for taxes. You must register your company for GST/QST if :

  • Making “taxable supplies” (commercial activities subject to GST/QST)
  • You are not a “small supplier” (your business revenues exceed $30,000 in a single quarter or over four consecutive quarters).

However, there are some special cases related to the application of the GST/QST. For example, for suppliers outside Quebec. To find out more, visit the Revenu Québec website.

Steps to register your business for GST/QST

The process of registering your business for GST/QST is relatively straightforward. First, you need to determine what type of business you are:

  • Individuals in business (self-employed)
  • Corporations
  • Partnerships
  • Trusts
  • Cooperatives
  • Etc.

Next, you must indicate whether the company’s head office is in Canada and whether you are the company’s ex-officio representative. In addition to entering your contact details, you must create a temporary code to leave the service and return anytime.

To start registering your business for GST/QST, use Revenu Québec’s online services.

Tax obligations of registered companies

Regardless of your sales, you must meet the tax obligations of Revenu Québec and the Canada Revenue Agency (CRA). Here are a few regulations and laws to be aware of if you’re a Quebec entrepreneur:

  • Quebec tax system
  • Labor standards
  • Health and safety at work
  • Environment Act
  • Consumer protection
  • Protection of personal information
  • Access to information

Don’t hesitate to seek advice from professionals and specialists.
