The GST/HST return reports sales tax collected, input tax credits, adjustments, and the resulting net tax.
A GST/HST return is the CRA sales-tax return used by registered businesses to report GST/HST activity for a filing period.
This term matters because it is easy for new business owners to think only in personal income-tax terms. A GST/HST return is different. It belongs to the sales-tax system and creates its own filing cycle, calculation, and remittance workflow.
Once a business is registered for GST/HST, the business may have to file GST/HST returns for the relevant reporting periods. Those returns focus on GST/HST reporting, not on the broader T1 income-tax calculation.
This is why a sole proprietor can have both a personal income-tax return and a GST/HST return workflow at the same time. The T1 return handles income-tax reporting. The GST/HST return handles the registered sales-tax side of the business.
Current CRA filing guidance makes three timing points especially important:
| Reporting period | Filing deadline | Payment deadline |
|---|---|---|
| Monthly | 1 month after the end of the reporting period | Same as filing deadline |
| Quarterly | 1 month after the end of the reporting period | Same as filing deadline |
| Annual with December 31 year-end and business income | June 15 | April 30 |
| Annual in most other cases | 3 months after fiscal year-end | Same as filing deadline |
CRA also says every registrant must file a return for each reporting period even if there were no transactions, no net tax to remit, or the business is closing the account. That kind of filing is often called a nil return.
For current periods ending in 2024 and later, the CRA also says most GST/HST registrants must file electronically unless a listed exception applies.
A self-employed business owner files a T1 return for personal income tax but also prepares a GST/HST return for the registered sales-tax activity. The two filings are related to the same business activity, but they are not the same return.
If the owner is an annual filer with business income and a December 31 fiscal year-end, the filing deadline and payment deadline are not the same. The return can usually be filed by June 15, but payment is generally due by April 30.
A GST/HST return is not the same thing as the T1 return.
It is also not simply a payment form. The return reports the sales-tax activity for the filing period and leads to the remittance result.
It is also not optional just because the period was quiet. CRA guidance requires a return for each reporting period, including a nil return when there is nothing to report.
Is a GST/HST return just another name for the T1 return? Answer: No. It is a separate CRA sales-tax return for registered businesses.
Why can a sole proprietor have both a T1 return and a GST/HST return? Answer: Because income tax and registered GST/HST reporting are separate filing workflows.
Filing periods, methods, and return details can vary by account and current CRA rules, so businesses should use current official guidance when preparing an actual return.
