For every sale where you did not collect GST or QST, you must keep proof that the purchaser is an Indian registered under the Indian Act, a band council, a tribal council or a band-empowered entity.

When the purchase is made on a reserve by an Indian, the invoice must include the registration number from the person's Certificate of Indian Status issued by Indigenous Services Canada.

The band name and family number (commonly known as the “band number” or “treaty number”) are also acceptable.

When a band council, a tribal council or a band-empowered entity makes a purchase on a reserve, the purchaser must provide a document certifying that the property is being acquired by a band council, a tribal council or band-empowered entity.

When an Indian, a band council, a tribal council or a band-empowered entity makes a purchase off a reserve, you (as the vendor) must keep, in addition to the registration number and the document from the band council, tribal council or band-empowered entity, proof that you or your agent delivered the property to a reserve.

If you use your own vehicle to deliver property to a reserve, you must keep proof in your files. You can do this using form LE-20-V, Proof of Delivery to a Reserve.

In the case of services, the document must certify that the services are being acquired by a band council, a tribal council or a band-empowered entity for band management activities or for real property situated on a reserve.
