Sales tax obligations differ depending on the province, registration status and activities of the business.

GST

The Goods and Services Tax is a federal sales tax that applies in Canada in accordance with the applicable tax rules.

HST

The Harmonized Sales Tax combines federal and participating provincial sales tax components in provinces where HST applies.

QST

The Quebec Sales Tax is Quebec's provincial sales tax and may apply in addition to GST for businesses subject to Quebec sales tax requirements.

Frequently asked questions

GST/HST & QST FAQs

How much does sales tax return preparation cost?
Fees depend on the periods to file, transaction volume, quality of the records and accounting work needed. A written proposal confirms the scope and fees. See the information needed for a quote.
Is a GST/HST or QST return the same as an income tax return?
Sales tax returns report information under the GST/HST or QST system. Personal and corporate income tax returns are separate filings. For incorporated businesses, T2 corporate tax services can be coordinated under the agreed scope.
How often do businesses file GST/HST returns?
Reporting frequency can vary by account and circumstances. Businesses may have monthly, quarterly or annual reporting periods. Your specific reporting period should be confirmed using the information associated with your tax account.
Can you prepare both GST and QST returns?
Yes. Where both GST and QST reporting applies, the two returns can be addressed together as part of the agreed engagement.
Can you help with late or outstanding sales tax returns?
Assistance may be available for outstanding reporting periods when the required accounting records and supporting information can be obtained.
Do I need bookkeeping completed before filing GST/HST or QST?
Reliable accounting information is important when preparing sales tax returns. If bookkeeping is incomplete, additional reconciliation or bookkeeping work may be required before the return can be finalized.
Can the GST/HST and QST process be completed online?
Yes. CPA Firm Online is designed to provide routine accounting and tax services remotely through digital document exchange, email and telephone communication, subject to the requirements of the engagement.
Do you work with businesses outside Quebec?
Yes. GST/HST and related accounting support may be provided to clients across Canada, subject to the requirements of each file. QST-specific services apply where Quebec sales tax requirements are relevant.
