Whether you need to register for GST/HST depends on your business revenue and the type of supplies you sell. Most small businesses in Canada must register for GST/HST once their sales reach $30,000 over a four-consecutive-quarter period. However, some businesses are exempt from GST/HST, and others can choose to register voluntarily even if they haven't hit this threshold. Understanding the rules helps you stay compliant and claim input tax credits on business expenses. The $30,000 threshold is the key number for most small business owners. Here's what you need to know: - You must register when your total sales of taxable supplies exceed $30,000 over any four consecutive calendar quarters - This calculation includes sales made before you start actively operating (such as deposits or pre-launch revenue) - Once you hit the threshold, you have 30 days to register with the CRA - The threshold applies separately in each province for HST purposes - Timing matters: sales are counted by the quarter in which they occurred, not when money was received If you're unsure about your filing obligations, our Self-Employed Tax Estimator can help you track income and estimate your tax position.
You must register when your total sales of taxable supplies exceed $30,000 over any four consecutive calendar quarters. This threshold has remained the same for several years and applies across Canada, though each HST province tracks it separately.
Yes, you can register voluntarily even if your sales are below $30,000. This is often beneficial because it allows you to claim input tax credits on business expenses, which can improve your cash flow and competitiveness.
Exempt businesses include most health services, financial services, residential rent, eligible educational services, charities, and public transit. If you're in an exempt sector, you generally cannot register and cannot claim input tax credits on purchases.
Most small businesses file quarterly, but businesses with less than $1.5 million in annual sales can elect to file annually. You'll receive a GST/HST account number and reporting schedule when you register.
The CRA can assess penalties and interest on any GST/HST you should have collected and remitted. You also lose the ability to claim input tax credits on expenses incurred before registration, which can cost your business money.
