The Goods and Services Tax (GST) is a federal tax applied to most goods and services sold in Canada. The Harmonized Sales Tax (HST) combines the federal GST with provincial sales tax in participating provinces and is administered by the Canada Revenue Agency (CRA).

Sales tax compliance involves registering for GST/HST when required, charging the correct tax, maintaining accurate records, filing returns on time, and remitting collected taxes to the CRA.

Businesses generally must register for GST/HST if their taxable revenues exceed $30,000 in a single calendar quarter or over four consecutive calendar quarters. Voluntary registration may also be available for some businesses.

A GST/HST number is a unique business account number issued by the CRA that allows businesses to collect, report, and remit GST/HST.

Failure to register when required may result in penalties, interest charges, and the obligation to pay GST/HST that should have been collected from customers.

The applicable tax depends on the province or territory where the supply is made. Different provinces have different GST/HST requirements and rates.

Filing frequency may be monthly, quarterly, or annually, depending on the size and revenue of the business and the reporting period assigned by the CRA.

Businesses typically need records of sales, collected GST/HST, purchases, expenses, input tax credits, adjustments, and prior filing information.

Input Tax Credits allow eligible businesses to recover GST/HST paid on business-related purchases and expenses used in commercial activities.

ITCs reduce the amount of GST/HST that a business must remit to the CRA by offsetting taxes paid on eligible business expenses.

Eligible expenses may include office supplies, rent, utilities, professional services, equipment purchases, marketing costs, and other business-related expenditures.

Businesses should retain invoices, receipts, contracts, supplier information, and supporting documentation that clearly show GST/HST paid.

Late filings can result in penalties, interest charges, delayed refunds, and increased attention from tax authorities.

Errors can often be corrected through adjustments, amended filings, or future return corrections. Professional assistance can help ensure corrections are handled properly.
