Why Accurate GST/QST Filing Matters For Québec Businesses

In Québec, most businesses must collect Goods and Services Tax (GST) and Québec Sales Tax (QST), known in French as Taxe sur les produits et services (TPS) and Taxe de vente du Québec (TVQ). These consumption taxes apply to the sale of most goods and services. Filing and remitting these taxes properly is not optional – every registered business must file a GST and QST return for each reporting period, even if there is no tax to remit. Accurate filing matters because:

• Avoiding Penalties: Revenu Québec imposes fines and interest for late filings or payments. For example, monthly and quarterly GST/QST returns are due one month after the end of the period. Missing a deadline even by a day can trigger penalties.

• Staying Compliant: Proper GST/QST reporting is a legal obligation. Québec businesses are required to register for GST/QST once they exceed $30,000 in taxable sales in a quarter or year. Non-compliance can jeopardize your standing with tax authorities.

• Cash Flow & Credits: Filing correctly ensures you recover all eligible Input Tax Credits (ITCs) and Input Tax Refunds (ITRs) – the GST/QST you paid on business purchases. These credits can significantly reduce how much tax you owe or even result in a refund if your expenses exceed your sales tax collected.

• Peace Of Mind: Knowing that your business taxes are handled accurately lets you focus on operations. It also prevents the stress of audits; both CRA and Revenu Québec increasingly use digital cross-checks to flag discrepancies in filings.

In short: Timely, accurate GST/QST filing is critical to keep your business running smoothly and to avoid giving the government any more money (or information) than necessary. Next, we'll look at the advantages of getting professional help with these filings.
