GST/HST for Canadian Freelancers: Complete Guide [2026]

GST/HST confuses almost every new Canadian freelancer. Do I charge it? When do I register? What is an ITC? This guide answers all of it — and shows you how it affects the rate you need to charge. Use our Canadian freelance rate calculator to see the exact GST/HST threshold in your calculations.

What Is GST/HST?

• GST (Goods and Services Tax): Federal 5% tax on most goods and services in Canada.
• HST (Harmonized Sales Tax): A combined federal + provincial tax used in Ontario (13%), Nova Scotia, New Brunswick, Newfoundland, and PEI (15%).
• PST (Provincial Sales Tax): Additional provincial tax in BC (7%), Manitoba (7%), and Saskatchewan (6%) — collected separately from GST.
• QST (Quebec Sales Tax): Quebec's equivalent at 9.975%, collected in addition to GST.

As a freelancer providing taxable services, you eventually become a tax collector for the CRA. You add GST/HST to your invoices and remit it quarterly or annually.

The $30,000 Registration Threshold

You must register for a GST/HST number when your total taxable revenue (not profit — gross billings) exceeds $30,000 in any rolling 12-month period.

You can register voluntarily before $30,000. This is often wise because early registration lets you claim Input Tax Credits (ITCs) on business expenses from day one. If you plan to hit $30,000 within the year, registering early saves time and avoids the scramble.

How to Register

1. Go to the CRA's My Business Account portal at canada.ca
2. Register online, or call 1-800-959-5525
3. CRA assigns you a 9-digit Business Number + RT0001 suffix (e.g., 123456789 RT0001)
4. You receive a filing frequency assignment — quarterly is most common for freelancers

What to Charge Your Clients

Once registered, add the appropriate rate to all Canadian invoices based on the client's province:

International clients: If your client is outside Canada, your services are generally zero-rated — you charge 0% GST/HST but still get to claim ITCs on your Canadian expenses. This is one of the biggest tax advantages of serving international clients.

Input Tax Credits (ITCs) — The Hidden Benefit

Here is the part most freelancers miss: once registered, you can recover the GST/HST you paid on business expenses. This is called an Input Tax Credit.

ITC-eligible expenses include:

• Laptop, monitor, phone (business-use portion)
• Software subscriptions: Adobe, Figma, GitHub, Notion, Slack
• Home office expenses (proportional to business use)
• Professional development courses and conferences
• Accounting software (FreshBooks, Wave, QuickBooks)
• Office supplies and equipment
• Business meals (50% of the GST/HST portion)
• Professional association fees

If you spent $5,000 on business expenses with $250 in GST, you recover that $250 in your return. Over time, ITCs meaningfully reduce your net tax burden.

Filing Your GST/HST Return

Standard Method (Quarterly)

1. Collect GST/HST on all Canadian client invoices throughout the quarter
2. Track GST/HST paid on business purchases (your ITCs)
3. Calculate: GST/HST Collected − ITCs = Amount to Remit
4. File online via My Business Account before the quarterly due date

Quick Method (Simplified for Small Businesses)

If your revenue is under $400,000, you can elect the Quick Method:

• Remit a flat percentage of your gross revenues instead of tracking individual ITCs
• For services in Ontario: remit 8.8% of gross revenues (instead of collecting 13% and subtracting ITCs)
• Simpler bookkeeping, but you give up the right to claim most ITCs

The Quick Method often saves money for freelancers with low business expenses. Run both calculations annually to choose the better option.

Four Common GST/HST Mistakes

1. Mixing GST with operating income: GST is not your money. Keep it in a separate savings account (labelled "Tax") until remittance day.
2. Forgetting to update existing clients: Once registered, all future invoices — even to ongoing clients — must include GST/HST. Notify clients 30 days before.
3. Not claiming all ITCs: Many freelancers claim only obvious purchases and miss subscriptions, professional development, and partial home office costs.
4. Missing filing deadlines: Late-filing penalties start at 1% of the balance owing per month.

Quebec: A Special Case

Quebec freelancers must register separately with Revenu Québec for QST once revenue hits $30,000. You file a separate QST return, and the combined effective rate for Quebec-based clients is 14.975%. The rate calculator handles Quebec's combined rate in the GST/HST display.

How GST/HST Affects Your Freelance Rate

GST/HST does not directly affect your take-home income — it is collected from clients and remitted to CRA. However, it does affect cash flow significantly. A freelancer billing $10,000/month collects $11,300 (with 13% HST in Ontario) but must set aside that $1,300 for CRA.

Understanding this flow is critical when calculating your freelance rate. Your rate calculation should be based on your before-GST billing amount — the tax is on top.
