$1,000 subtotal + $130 HST = $1,130 total. iBill.ca calculates this automatically on every Ontario invoice.
Ontario uses the Harmonized Sales Tax — a single 13% rate that combines federal and provincial tax into one line on your invoice.
Ontario invoices show HST as a single line — there's no separate GST or PST because HST is harmonized. Try the calculator: Ontario HST Calculator.
If you're a business based in Alberta, BC, Quebec, or anywhere else in Canada, and you're invoicing a client located in Ontario, the Canada Revenue Agency's place-of-supply rules determine which tax you charge — and it's not your province's rate. For most services and digital products delivered to an Ontario client, you charge 13% Ontario HST, not your home province's GST or PST. iBill.ca handles this automatically based on your client's province on file.
This is not something you can figure out with a tax calculator alone — the calculator gives you the rate, but the invoice software enforces the place-of-supply logic across every line item, every client, and every return. iBill.ca's address-based tax engine means you never have to remember which rate to apply — just pick the client and the correct tax appears.
A few Ontario-specific invoice rules that iBill.ca handles automatically but you should know about.
CRA's Excise Tax Act Section 3 requires your 9-digit Business Number followed by the RT0001 program identifier (e.g., 123456789RT0001) on any invoice to an HST registrant for a supply over $30. iBill.ca prints this automatically once you add it to your organization profile — you never have to remember it per-invoice.
Ontario provides an automatic point-of-sale rebate that removes the 8% provincial portion of HST for specific categories — children's clothing and footwear, children's car seats, diapers, feminine hygiene products, print newspapers, and books. If you invoice these items, charge 5% GST only (not 13% HST). iBill.ca supports tax-exempt line items for these cases — mark the line as exempt and the reduced rate flows through automatically.
CRA assigns filing frequency based on your annual taxable supplies: annual ($1.5M or less), quarterly ($1.5M–$6M), or monthly (over $6M). Most Ontario small businesses start on annual filing. iBill.ca generates HST return reports for any period you choose — run them quarterly or annually depending on your assigned schedule. See CRA tax reporting for the full workflow.
Ontario HST registrants can claim ITCs on HST paid for business expenses — including the business-use portion of home office costs, vehicle expenses, and meals (50%). iBill.ca's expense tracking automatically captures HST paid on each expense and flows it into your ITC total on the return. No manual reconciliation at quarter-end.
Every feature an Ontario small business needs — tax, accounting, payments, and CRA-ready reports in one place.
When you select an Ontario client, HST is calculated automatically at 13% on the invoice subtotal. No manual entry, no missed calculations. Built from the canonical CRA rate table.
