Small Supplier Status in Canada: GST/HST Explained

In Canada, small supplier status is a GST/HST concept that allows a sole proprietor to operate without registering for, charging, or collecting GST/HST as long as taxable revenue stays under the CRA's small supplier threshold. It is one of the first tax questions a new business owner faces, and the answer depends on your taxable supplies over four consecutive calendar quarters — not on your profit, your business structure, or how long you have been operating.

What small supplier status actually means

Small supplier status applies only to the GST/HST system. It does not change how you report business income on your T1 return, and it does not affect CPP contributions on self-employment income. If you qualify, the CRA generally does not require you to open a GST/HST account, which means you do not charge the tax on your invoices and you cannot claim input tax credits (ITCs) on the GST/HST you pay for business purchases.

• You are not required to collect GST/HST from customers.
• You cannot recover GST/HST paid on expenses through ITCs.
• Your invoices typically show no GST/HST, or show it at zero.
• You may still register voluntarily if it suits your business.

Being a small supplier is not the same as selling exempt supplies. Certain goods and services, such as most basic groceries and prescription drugs, are zero-rated or exempt no matter how large the business is. Small supplier status is about your revenue level, not the type of product you sell.

How the small supplier threshold is measured

The small supplier threshold is based on the total value of your taxable supplies — revenue from taxable sales of goods and services — over four consecutive calendar quarters. The CRA publishes the current dollar amount, and it is reviewed periodically, so confirm the latest figure on the CRA website rather than relying on an older article or a second-hand summary.

Several details matter when you run the test:

1. The window is four consecutive calendar quarters, which rarely lines up with your fiscal year or the calendar year.
2. Zero-rated supplies generally count toward the total; most exempt supplies do not.
3. Sales made through a partnership are usually counted separately from your own sole proprietorship.
4. Taxi and ride-sharing drivers, and businesses selling certain regulated products, generally must register regardless of revenue.
5. Once you cross the threshold, the CRA allows only a short window to register and start charging tax, so confirm the current timing rule before your next invoice.

Small supplier or registered: what changes

The practical difference comes down to five things.

Registering voluntarily

You can register for a GST/HST account even if you are under the threshold. Voluntary registration is often useful if you sell mainly zero-rated items such as exports, if you buy significant taxable inputs, or if your customers are businesses that can claim ITCs and expect to see GST/HST on your invoices. It may be less attractive if you sell directly to consumers, since adding GST/HST raises your effective price.

Registration is a commitment. Once you open a GST/HST account you take on filing obligations, record-keeping requirements, and the responsibility to remit what you collect. It also means keeping collected tax separate from your own revenue, which is a common stumbling block for new sole proprietors.

Small supplier status and your income tax

GST/HST registration and income tax reporting are two separate systems. Whether or not you are a small supplier, you still report business income and expenses on Form T2125, Statement of Business or Professional Activities, filed with your T1 return. You still pay income tax on net profit and CPP on net self-employment income.

What changes with GST/HST registration is only the indirect tax layer: you collect tax on behalf of the government, claim ITCs on eligible purchases, and remit the difference. That collected tax is never your revenue and should not be reported as income. For a walkthrough of reporting business revenue correctly, see how to report self-employment income in Canada.

Practical steps to stay compliant

1. Track taxable revenue by calendar quarter so you always know where you stand against the threshold.
2. Watch the rolling four-quarter total, not just the current year.
3. If you cross the threshold, register through CRA My Business Account — see do I need to charge GST/HST.
4. Once registered, follow the GST/HST return filing process and claim eligible ITCs, explained in input tax credits in Canada.
5. Confirm the rate you must charge using the GST/HST rates by province, since rates vary and some provinces have different rules.
6. Keep records for the retention period the CRA requires so any threshold calculation can be supported.

Where to confirm the current rules

Because the threshold and the timing rules can change, verify before you register or stop charging tax. The CRA's GST/HST pages on canada.ca set out the current threshold, the registration process, and filing obligations, and your CRA My Business Account shows your own account status. Provincial rules matter too: Quebec administers its own sales tax through Revenu Québec, and registration for provincial programs may be separate.
