What is the GST/HST registration threshold in Canada for 2026?

For 2026, the threshold for mandatory GST/HST registration remains at $30,000 CAD in total taxable supplies over four consecutive calendar quarters. This includes sales made by yourself and any associates. If your revenue exceeds this limit in a single quarter or over a 12 month period, you must register within 30 days of the day you are no longer a small supplier. Digital economy businesses selling to Canadian consumers may face lower or different thresholds depending on their nexus and business model.

When are 2026 GST/HST returns due for annual filers?

For most small businesses and sole proprietors with an annual reporting period ending December 31, 2026, the GST/HST return is due by June 15, 2027. However, any net tax owed must be paid by April 30, 2027, to avoid interest charges. If your business is a corporation with an annual reporting period, the return and payment are generally due three months after your fiscal year end.

Can I voluntarily register for GST/HST if my revenue is under $30,000?

Yes, you can register voluntarily even if your revenue is below the $30,000 threshold. Voluntary registration allows you to claim Input Tax Credits (ITCs) to recover the GST/HST paid on business expenses, equipment, and rent. This is particularly beneficial for startups with high initial costs but low revenue. Once registered, you must collect and remit tax on all taxable sales and remain registered for at least one year before you can request cancellation.

What are the 2026 GST/HST rates by province?

As of 2026, the tax rates vary by province. Use the 5 percent GST rate for sales in Alberta, British Columbia, Manitoba, Northwest Territories, Nunavut, Quebec, Saskatchewan, and Yukon. Use the Harmonized Sales Tax (HST) rate of 13 percent in Ontario. Use the 15 percent HST rate in New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island. Note that Quebec also applies a 9.975 percent QST which is separate from the federal 5 percent GST.

2026 Canada GST/HST Registration Guide for Small Businesses

TL;DR: In 2026, Canadian small businesses must register for a GST/HST account once their worldwide taxable revenue exceeds $30,000 CAD over four consecutive quarters. Registration allows for the recovery of sales tax paid on business inputs through Input Tax Credits, but requires strict adherence to quarterly or annual filing deadlines.

Navigating GST/HST Registration for Canadian Small Businesses in 2026

Understanding the 2026 Canada GST/HST registration requirements is essential for any entrepreneur operating within the Canadian market. The Goods and Services Tax (GST) is a federal tax applied to most supplies of goods and services in Canada. In several provinces, this is combined with provincial sales tax to form the Harmonized Sales Tax (HST). As a business owner, you act as an agent for the Canada Revenue Agency (CRA) by collecting these taxes from customers and remitting them to the government. Failing to register when required can lead to significant back taxes, interest, and penalties that can jeopardize a startup cash flow.

The Small Supplier Threshold and Mandatory Registration

For the 2026 fiscal year, the CRA maintains the small supplier threshold at $30,000 CAD. You are considered a small supplier and are not required to register for GST/HST if your total taxable revenues (before expenses) from all your businesses are $30,000 or less in the last four consecutive calendar quarters.

There are two specific triggers for mandatory registration. First, if you exceed the $30,000 limit over four consecutive quarters, you lose your small supplier status. You have 30 days from the end of the month following that period to apply for an account. Second, if you exceed the limit in a single calendar quarter, you are no longer a small supplier at the moment of the sale that took you over the limit. In this case, you must register within 30 days of that specific sale and begin collecting tax immediately on the transaction that exceeded the threshold.

Voluntary Registration and Input Tax Credits (ITCs)

Many founders choose to register voluntarily even if they earn less than the $30,000 threshold. The primary advantage of voluntary registration is the ability to claim Input Tax Credits (ITCs). An ITC allowing you to recover the GST/HST you pay on business purchases such as laptops, software subscriptions, office space, and inventory.

However, voluntary registration comes with administrative responsibilities. You must charge GST/HST on all of your taxable sales, file regular returns even if you have zero income to report, and maintain meticulous records for at least six years. For service based businesses with very low overhead, remaining a small supplier might be simpler. For capital intensive startups, the ITCs often outweigh the compliance costs.

Digital Economy and Cross Border Rules

The 2026 landscape continues to enforce strict rules for digital economy participants. If you operate an e-commerce platform or provide digital services (such as SaaS or streaming) to Canadian consumers, you may be required to register under the simplified GST/HST regime. This applies to non-resident vendors who have no physical presence in Canada but exceed the $30,000 threshold in sales to Canadian residents. Unlike the standard registration, simplified registrants generally cannot claim ITCs but must collect and remit tax on all digital supplies.

Filing Frequencies and Reporting Periods

Your reporting period is the timeframe for which you must prepare and file your GST/HST returns. This is usually determined by your annual revenue. Most small businesses with less than $1.5 million in annual taxable supplies are assigned an annual reporting period by default. You can, however, elect to file monthly or quarterly if you prefer more frequent reconciliations or expect regular refunds from ITCs.

2026 Filing and Payment Deadlines

Filer Type	Reporting Period	Return Due Date	Payment Due Date
