Starting a freelance business comes with specific tax responsibilities. Understanding when and how to register for a GST/HST account is critical for self-employed newcomers.
The government requires certain business owners to register for a GST/HST account, collect this tax from clients, and remit it to the CRA. GST/HST is a consumption tax that your clients pay and you collect on behalf of the government. Both sole proprietors and independent contractors are subject to these rules if they meet the registration threshold. Failing to register when required can result in the CRA charging you the uncollected sales tax from your own revenue.
If your worldwide gross revenue from taxable supplies stays below $30,000, you are generally considered a small supplier and are not legally required to register. There are two separate ways the threshold can be crossed, with different effective registration dates. Test 1 — Four consecutive quarters: if your total revenue over any four consecutive calendar quarters exceeds $30,000, you must register within 29 days after the end of the month in which you crossed the threshold. Test 2 — Single quarter: if you earn more than $30,000 from taxable supplies in a single calendar quarter, you lose small supplier status immediately on the day of the specific sale that pushed you over $30,000. The registration deadline differs between these two tests — review the CRA's current GST/HST registration guidance at canada.ca for precise timelines.
Certain businesses must register before making their first sale, regardless of expected revenue. If you work as a taxi driver or commercial ride-share driver (such as Uber or Lyft), you must register for a GST/HST account before you carry your very first passenger. Check whether your specific industry has mandatory immediate-registration requirements at canada.ca.
Even if your income is below $30,000, you can register voluntarily. The main advantage is the ability to claim Input Tax Credits — recovering the GST/HST you paid on legitimate business expenses like laptops and software. This can be particularly valuable if you have significant startup costs.
The GST/HST rate you charge generally depends on where your client is located, but place-of-supply rules are complex and vary by type of supply. For many services, the recipient's address is the key factor — but this is not universal. Services to clients outside Canada may qualify as zero-rated exports in some circumstances, but not automatically in every case. Review the CRA's place-of-supply rules at canada.ca, or consult a tax professional if you serve clients in multiple provinces or internationally.
Registering for a GST/HST account is free through the CRA Business Registration Online portal at canada.ca. The CRA assigns you a Business Number with an RT account identifier. This number appears on all your invoices. Collect the applicable tax, hold it until your reporting period, file your GST/HST return electronically, subtract eligible Input Tax Credits, and remit the balance to the CRA.
