Ontario Invoice Template - Canada

You must charge and display HST (13% in Ontario) if your business is HST-registered with the Canada Revenue Agency (CRA) and your client is subject to HST. However, if your client is also HST-registered, they can claim the HST as an input tax credit, so the tax doesn't create a net cost for them. If your annual revenue is below the HST registration threshold (currently $30,000), you may not be required to register. Non-residents and certain service providers have different rules, so confirm your specific situation with CRA. Always display your HST registration number prominently on invoices.

Your Ontario invoice should include your business name, complete address, and HST registration number (if applicable). While not always mandatory, including your business phone number and email builds credibility. Some businesses operating as proprietorships list a personal name; others use registered business names. Your client's full name and address are equally important for record-keeping and payment tracking. If you're a contractor or freelancer, your business registration number (BN) should be visible—this ensures CRA compliance and professional appearance. The template automatically positions these elements correctly, but verify accuracy before sending.

Yes, but with adjustments. If your client operates in Ontario, use the 13% HST rate. If they're in Quebec, you'd typically apply GST (5%) and QST (9.975%); in British Columbia, use GST (5%) and PST (7%). The Ontario template handles the HST calculation, but you'll need to modify tax fields for out-of-province clients. Some businesses serving multiple provinces use simplified invoices showing GST only, then adjust based on the client's province. If your client provides a valid HST registration number and they're registered, reverse charging may apply—consult CRA guidance for your specific situation.

Yes. Certain organizations—including charities, not-for-profits, public sector bodies, and educational institutions—may be HST-exempt or entitled to HST relief under CRA rules. These clients must provide proof of exemption status. On invoices to exempt entities, you do not charge HST. However, you cannot claim input tax credits on your business expenses related to those exempt sales. Document the exemption reason on each invoice for your records. Your Ontario template should allow you to create invoices without HST when needed. Always request exemption certificates from clients claiming exemptions to protect your business and maintain CRA compliance.

Yes, but Ontario contract law limits what's reasonable. Standard practice in Ontario is 1–2% per month (12–24% annually) or the Bank of Canada prime rate plus a reasonable margin. Clearly state your late payment terms on the invoice—for example, "Payment due within 30 days; interest accrues at 1.5% per month on overdue balances." Avoid excessive or punitive rates, which could make the invoice unenforceable. Different industries have different expectations: contractors often allow net-30; consultants may require net-15. Specify terms upfront to reduce payment disputes and set clear expectations with clients.

List all payment methods you accept: bank transfer (e-transfer via Interac is extremely popular in Ontario), credit card, check, or digital wallets. Include your bank details for direct deposits or e-transfer handle prominently at the bottom of your Ontario invoice. Many Ontario businesses prefer e-transfer for its speed and security. If you're an incorporated business, your business bank account name should match your legal business name exactly. Include your business address for check payments. Accepting multiple payment options reduces payment friction and speeds up cash flow. Your template should have clearly labeled sections for payment instructions.

The Canada Revenue Agency requires you to keep all business records, including invoices, for at least six years from the end of the year they relate to. Invoices are critical for proving income and HST claims, so retention is essential for audits or disputes. Ontario does not have additional retention rules beyond federal CRA requirements. Whether you store invoices digitally or in hard copy, they must be retrievable and legible. Digital copies are acceptable if they're exact reproductions of originals. Consider cloud storage or external backups to protect against loss. Proper record-keeping protects your business during audits.

Both contractors and consultants use invoices, but expectations differ. Contractors typically bill hourly or by project with detailed line items (labor, materials, equipment); invoices often include job site addresses. Consultants usually bill by hour or deliverable with less detail, emphasizing expertise and outcomes. Ontario contractors must include their WSIB account number if required by law. Both must display HST and business registration numbers. Contractors often invoice weekly or bi-weekly; consultants typically monthly. The Ontario template adapts to both, but adjust line-item descriptions and payment terms to match your business model and client expectations.
