GST/HST Filing in Canada: What You Need to Know

If you're a business owner in Canada, understanding GST/HST is critical. Here's everything you need to know about registration, filing, and compliance.

What is GST/HST?

GST (Goods and Services Tax) is a 5% federal tax. HST (Harmonized Sales Tax) combines GST with provincial sales tax and ranges from 13-15% depending on the province.

Do You Need to Register?

You must register for GST/HST if your total revenue exceeds $30,000 in any 12-month period. Some businesses can register voluntarily even if below this threshold.

Filing Frequency

• Monthly: Large businesses remit monthly
• Quarterly: Medium-sized businesses file quarterly
• Annually: Small businesses may file annually

Key Filing Dates

• Monthly filers: Payment due by the 27th
• Quarterly filers: 1 month after quarter-end
• Annual filers: 3 months after year-end

GST/HST Credit

Registered businesses can claim Input Tax Credits (ITCs) on purchases. This means you only remit the GST/HST collected from customers, minus the GST/HST paid on business expenses.

Tips for Compliance

• Keep detailed records of all sales and purchases
• Maintain receipts for GST/HST paid
• Use accounting software to track GST automatically
• File on time to avoid penalties (5-50% of unpaid amounts)

Pro Tip: Many small businesses are eligible for GST refunds even with zero revenue in low-revenue periods. Let us calculate your GST/HST obligations and maximize your credits.
