Simple Invoice Template - Canada

GST (Goods and Services Tax) is a 5% federal tax that applies nationwide. HST (Harmonized Sales Tax) combines federal and provincial tax, ranging from 13% to 15% depending on the province. You charge GST if your province hasn't adopted HST, and HST if you operate in Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador, or Prince Edward Island. Alberta, Yukon, Northwest Territories, and Nunavut use only the 5% GST. Check your provincial business registry to confirm your jurisdiction's tax rate, then apply the correct rate to invoices sent to clients within that province.

Only if you're registered for GST or HST with the Canada Revenue Agency. If your annual revenue exceeds the registration threshold (currently $30,000), you must register and include your account number on invoices. Unregistered small businesses and sole proprietors below the threshold should not display a GST/HST number—doing so could incorrectly imply registration status. If registered, your account number appears on your CRA Notice of Assessment and must be clearly displayed on all invoices for tax purposes and client credibility.

Yes, but you'll need to adjust the tax rate based on your client's location. Each province has different HST or GST rates, so you cannot use a single fixed rate across all invoices. The template's structure remains the same—you simply update the tax percentage when invoicing clients in different provinces. If your business is registered in one province but regularly serves clients across Canada, ensure your invoicing system clearly shows which tax rate applies to each transaction. This prevents compliance issues with the CRA and keeps client records accurate.

Canadian invoices must include your business name and address, the client's name and address, a unique invoice number, the invoice date, a clear description of goods or services provided, the quantity and price of each item, payment terms, and the total amount due. If GST or HST is applicable, it must be shown separately with the applicable rate. Include your GST/HST account number only if registered. The CRA doesn't mandate a specific format, so this simple template covers all legal requirements. Missing information can create issues during CRA audits or when clients need documentation for tax purposes.

Absolutely. Service-based businesses—consultants, contractors, freelancers, and professionals—use simple invoice templates most effectively. Unlike product invoices with stock numbers and SKUs, service invoices need clear descriptions of work performed, hourly rates or project fees, and time breakdowns. This template's line-item structure accommodates hourly billing, project-based fees, retainers, and milestone payments. The simplicity actually works in your favor: clients appreciate straightforward invoices without unnecessary fields. The template's flexibility makes it ideal for Canadian service providers across consulting, design, trades, and professional services.

No—Canadian GST and HST do not apply to exports of services to non-residents. This is called zero-rating and applies when your client is outside Canada. Consulting, software development, and other professional services provided to US or international clients are considered exports and should not include Canadian tax. You must document the client's location and the export nature of the transaction. Keep records showing the foreign client's address and proof of services delivered outside Canada. This applies even if the payment is received in Canadian dollars—the tax exemption is based on client location, not currency.

Create separate line items or invoices clearly identifying the tax rate and province for each transaction. If one invoice includes services billed to clients in Ontario (HST 13%) and Alberta (GST 5%), calculate tax separately for each province's portion. Use invoice notes to clarify which services apply to which province. This transparency protects you during CRA audits and prevents client confusion. For businesses regularly serving multi-province clients, consider using accounting software that automates tax rate selection by postal code. Accurate province-specific tax calculation demonstrates compliance and professionalism to clients and tax authorities.

If you're registered for GST or HST, you must retain invoices and supporting records for at least six years from the end of the year they were issued. The CRA uses these records to verify tax compliance and deductions. Even if you're not GST/HST registered, keeping invoices for six years is standard business practice for tracking income and client history. Store copies digitally or in hard copy in a secure location. Good invoice retention practices also help if clients dispute payments or timelines. Organized record-keeping makes tax filing easier and protects your business in case of a CRA inquiry.
