Ontario uses a single Harmonized Sales Tax (HST) at 13%, making tax recovery straightforward — every dollar of HST you pay on business purchases is fully recoverable through Input Tax Credits.
How your business purchases are taxed at the register.
Ontario operates under the Harmonized Sales Tax (HST), which combines the federal 5% GST with a provincial 8% component into a single 13% tax. For self-employed workers, this is the simplest system to manage — one tax rate, one line on your invoices, and one Input Tax Credit claim.
Because HST is fully harmonized, every cent of the 13% you pay on legitimate business expenses is recoverable when you file your GST/HST return. There is no split between recoverable and non-recoverable portions, unlike provinces with separate PST. Ontario adopted HST on July 1, 2010, replacing the old 8% PST + 5% GST system.
Ontario is home to the largest population of self-employed Canadians, with over 1.1 million sole proprietors. The province's diverse economy means ScanForTax processes everything from Bay Street IT consulting receipts to Muskoka construction invoices — all at the same 13% HST rate.

Claim ITCs on your GST/HST return
In Ontario, all HST paid on business expenses is recoverable through Input Tax Credits (ITCs). File your GST/HST return (quarterly or annually) and list total ITCs claimed. For invoices under $30, simplified documentation is accepted. For $30–$99, the supplier's GST/HST registration number is required. For $100–$499, full details including date and total are needed. For $500+, the supplier must also include your name or business name. Common claimable categories include office expenses, motor vehicle expenses, and telephone and utilities. ScanForTax automatically extracts HST amounts and validates invoice tier requirements.
3 advantages, 1 things to watch
Unlike BC or Saskatchewan where PST is a sunk cost, Ontario's HST is 100% recoverable. A $10,000 equipment purchase means $1,300 back in your pocket through ITCs.
The Ontario Trillium Benefit (OTB) is a personal credit — it does not reduce or interact with your business ITCs. You can claim both independently.
Before HST (pre-2010), Ontario exempted PST on certain items like children's clothing and books. Under HST, the full 13% applies to almost everything. Rebates exist for some items like new homes but not for typical business purchases.
Ontario previously restricted ITCs on certain expenses (energy, telecom, meals, vehicle fuel) for large businesses. These restrictions were fully phased out by July 2018 and do not affect small businesses or sole proprietors.
