Ontario Retail Sales Tax Purchase Exemption Certificate

Ontario’s Retail Sales Tax Purchase Exemption Certificate (form 013-3479) is the document a qualifying buyer gives a vendor or insurer so the seller can complete the transaction without charging the 8% RST on insurance premiums or other still-taxable supplies.¹ The purchaser fills it out, signs it, and hands it over at the time of the sale. If you do not provide a properly completed certificate, the supplier is required to charge the tax.

The certificate matters because RST still applies to a narrow set of transactions even after the HST took over most sales tax in 2010. The biggest one is insurance: premiums on taxable insurance contracts, group policies, and certain benefits-plan contributions attract 8% RST.² A quick boundary note: the certificate is not the route people use for private vehicle purchases, which carry their own 13% RST paid at registration rather than waived at the counter.

Who Can Use the Certificate

The form lists the categories of buyers eligible to claim an exemption. You need to fit one of them substantively, not just check the box:

Resellers buying taxable goods or services for resale rather than their own use.
Manufacturers purchasing machinery, equipment, or processing materials used directly in manufacturing.
Farmers and fishers buying equipment, tools, or machinery for those operations.
Registered charitable, religious, and benevolent organizations purchasing qualifying items.
Hospitals purchasing qualifying equipment.
First Nations individuals and bands purchasing property situated on a reserve, where the buyer holds a valid Certificate of Indian Status identity card.
Foreign entities and international organizations claiming a diplomatic exemption.

First Nations Purchasers

First Nations individuals, Indian Bands, and band councils can claim RST exemptions on insurance contracts and benefits plans relating to real or personal property situated on a reserve. Proof of registration is a valid federal Certificate of Indian Status identity card, or a Temporary Confirmation of Registration Document for those still waiting on the permanent card.¹

Foreign Diplomats and International Organizations

Diplomatic missions, consular posts, and international organizations such as UN agencies qualify, as do individual foreign representatives and officials who carry a DFATD identity card marked “D,” “C,” “I,” or “J” (the “J” card covering administrative, technical, and consular employees only). The exemption extends to the representative’s spouse but not to their children. An individual representative shows the DFATD card to the vendor when entering an insurance contract; a foreign entity or international organization provides a completed Purchase Exemption Certificate instead.³

How to Fill Out Form 013-3479

The blank form is on the Ontario Central Forms Repository. You, the purchaser, complete it. The fields to work through:

Purchaser identity: full legal name and current residential or business address.
Vendor permit number: if your business is registered for Ontario RST, include the number.
Exemption category: check the box that matches your reason for the claim, such as “Insurance/Benefit Plan,” “Machinery, Equipment, and/or Processing Material Purchased for Manufacturing,” or “Identity Card Type and Number” for First Nations purchasers. An “Other” line with a write-in field covers less common situations.
Description of goods or services: enough detail to match the purchase invoice or insurance contract.
Signature and date: your signature attests the information is accurate and every condition of the exemption is met.

Signing the form does not by itself create the exemption. You have to actually qualify. Leaving the category blank, or ticking one that does not fit your circumstances, is the kind of error that surfaces during an audit and can result in the exemption being denied after the fact.¹

Handing the Certificate to the Vendor

Give the completed certificate to the vendor or insurer at the time of the transaction. The vendor then processes the sale without collecting RST. Suppliers are responsible for checking that the certificate is properly completed and keeping a copy on file. Without a valid certificate or approved identity card in hand, the supplier must charge RST.¹

Records to Keep

Ask the vendor to reflect the tax-exempt status on the final invoice. That invoice is your evidence the tax was legally waived. Keep it. The vendor keeps their copy of the certificate; if they cannot produce it during a government audit, they can be held liable for the uncollected tax plus interest and penalties. From your side, an invoice showing the exemption is what you would reach for if your eligibility is later questioned.

Penalties for a False Certificate

A Purchase Exemption Certificate is a legal declaration, and giving false information on one is an offence under the Retail Sales Tax Act. The Act targets anyone who makes or participates in false or deceptive statements on a certificate, return, or answer required under the law. On conviction, penalties include fines up to $10,000 plus up to double the tax that should have been paid, imprisonment of up to two years, or both.⁴ Auditors compare what the certificate says against the purchaser’s actual circumstances.

If You Already Paid RST on an Exempt Purchase

If tax was charged on a transaction that should have been exempt (because you did not realize you qualified, or the vendor would not accept the certificate), you can apply to the Ministry of Finance for a refund. Your application and all supporting documents, including proof of tax payment, must be received within four years from the date the tax was paid.⁵ Pull together the original invoice, proof of payment, and documentation of your exempt status before filing; a complete package moves through faster than one the ministry has to chase.
