Independent Contractor Invoice Template - Canada

You must register for GST/HST if your revenue exceeds $30,000 in any four consecutive quarters. Even if you're below the threshold, you can choose to register voluntarily. Many contractors register early to claim input tax credits on business expenses. If you register, you must charge GST/HST on invoices and remit collected taxes to the CRA quarterly or by other prescribed schedules. Consult the CRA website or an accountant to confirm your specific registration requirements.

Canadian invoices must include your business name and address, client's business name and address, invoice number and date, clear description of services provided, quantity and rate for each line item, total amount owing, and your GST/HST registration number if applicable. The CRA expects invoices to clearly distinguish between taxable and tax-exempt services. Include payment terms and your preferred payment method. This documentation helps both you and your client maintain proper records for tax purposes and during audits.

The CRA evaluates control over your work, ownership of tools and equipment, financial risk (potential profit or loss), ability to serve multiple clients, and provision of your own benefits. True independent contractors control their schedule, use their own equipment, invest in their business, and accept financial risk. If a client controls your hours, provides tools, or requires exclusivity, you may be classified as an employee. Document these arrangements; misclassification can trigger CRA audits and result in back taxes and penalties.

Add the applicable tax to your invoice subtotal. Rates vary by province: 5% GST only in some provinces, and 13-15% HST in others. Show the subtotal, GST/HST amount separately, and the final total on your invoice. Some services are reduced or zero-rated, but most professional services are fully taxable. Your invoice total must reflect collected tax, which you remit to the CRA according to your filing schedule. Use province-specific rates based on the client's location, not yours.

Retain invoices and supporting financial records for at least six years from the end of the tax year they were created. The CRA can request these during audits. This retention period is critical for substantiating business expenses—you'll need invoices and receipts to justify deductions claimed on your tax return. Digital copies are acceptable if legible and complete. Some contractors keep records longer for business reference. Proper documentation demonstrates professionalism and protects you if disputed claims arise.

Invoice when you're a true independent contractor with control over your work and multiple clients. Clients issue a T4A only if they meet specific criteria: they claim you as a business expense and paid you $500 or more annually. Some clients request invoices for their records; others handle reporting differently. Clarify upfront whether they'll issue a T4A or simply pay your invoices based on their accounting requirements. Never assume—this distinction affects both their tax reporting and your record-keeping.

Common terms include Net 15, Net 30, or Net 45 (payment due 15, 30, or 45 days after invoice date). Many Canadian contractors offer 2% discounts for payment within 10 days to encourage faster payment. Specify your accepted methods: bank transfer (most common), e-transfer, cheque, or credit card. Include late payment expectations such as interest charges or collection procedures. Clear terms reduce misunderstandings and cash flow delays. For retainer-based work, specify billing dates and deposit requirements in your invoicing agreement.

Yes, GST/HST rates vary significantly by province, and your invoice must reflect the rate applicable to your client's location. Ontario clients (13% HST) invoice differently than Alberta clients (5% GST). Some services are exempt in specific provinces. Track where each client operates, not where you're based. If you invoice across provinces frequently, use invoicing software that automates rate calculation by location. This complexity is another reason to consult a Canadian accountant familiar with provincial tax variations.
