A Guide to Understanding GST/HST for Small Businesses

For small businesses in Canada, navigating the complex world of taxes can be a daunting task. One area that often raises questions is the Goods and Services Tax (GST) and the Harmonized Sales Tax (HST). In this guide, we'll break down the essentials to help small business owners gain a better understanding of their obligations and make informed decisions.


Understanding GST/HST Basics

GST and HST are consumption taxes that apply to most goods and services in Canada. While GST is a federal tax, HST is a combined federal and provincial tax that applies in certain provinces. The provinces that have adopted HST include Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island.


GST/HST Registration

As a small business owner, it's crucial to determine whether your business needs to register for GST/HST. Generally, businesses with annual revenues exceeding $30,000 must register. However, even if your revenues are below this threshold, voluntary registration may be beneficial, as it allows you to claim input tax credits (ITCs) on business expenses.


Collecting and Remitting GST/HST

Once registered, your business is required to collect GST/HST on taxable supplies. The rate varies depending on the province, so it's essential to know the applicable rate for your business location. Ensure that your invoices clearly indicate the amount of GST/HST collected.

On the flip side, you can also claim ITCs on the GST/HST you pay on eligible business expenses. This helps to reduce the overall tax burden on your business.


Filing GST/HST Returns

Small businesses registered for GST/HST must file regular returns, typically on a quarterly or annual basis. The return will include information on the GST/HST collected and paid, allowing the Canada Revenue Agency (CRA) to reconcile your tax obligations. Timely and accurate filing is crucial to avoid penalties and interest.


Special Considerations for Small Businesses

Small businesses may be eligible for the GST/HST small supplier threshold, allowing them to avoid registration until their revenues exceed $30,000. However, voluntary registration may still be advantageous to claim ITCs.

Additionally, certain supplies, such as basic groceries and certain healthcare services, are exempt or zero-rated, meaning they are not subject to GST/HST. Understanding the nuances of these categories can impact your tax liabilities.



Navigating the world of GST/HST as a small business owner requires diligence and a clear understanding of your obligations. By staying informed, ensuring proper registration, and filing accurate returns, you can manage your tax responsibilities effectively. Consulting with a professional CPA firm can provide valuable guidance tailored to your specific business needs, ensuring compliance and potentially optimizing your tax position. Remember, knowledge is power, especially when it comes to taxes!
