Background

In 1991, the Canada Revenue Agency (CRA) adopted an administrative arrangement with the Canadian Dental Association. Under the arrangement, a dentist who was a GST/HST registrant could, for each reporting period in a fiscal year, use an estimate up to a maximum of 35% of the total consideration charged for orthodontic treatments to represent the consideration for the supply of orthodontic appliances. This was used to estimate the extent of the dentist’s commercial activity for the reporting period.

However, at the end of the fiscal year, the GST/HST registrant dentist was required to determine the extent of their commercial activity by performing a reconciliation based on the actual amounts charged for orthodontic appliances. The reconciliation ensured that the dentist did not overclaim input tax credits (ITCs) on overhead expenses and purchases consumed, used, or supplied in the making of both taxable supplies (for example, cosmetic services and orthodontic appliances) and exempt supplies of dental services.

Throughout this document, where the term dentist is used, it refers to a dentist who is a GST/HST registrant. 

Revocation of administrative arrangement

The CRA has determined that the administrative arrangement is no longer appropriate and will be revoked. As the arrangement was only a guideline, it did not carry the weight of law and was not binding on the courts (such as the Tax Court of Canada). The administrative arrangement became redundant due to recent jurisprudence which determined that a dentist was able to claim ITCs in respect of supplies of orthodontic appliances that are supplied in conjunction with orthodontic services. Additionally, the administrative arrangement allows ITCs to be claimed in a manner that is contrary to the ITC provisions in the ETA.

The revocation of the administrative arrangement will be effective the first day of the GST/HST registrant’s fiscal year that starts on or after January 1, 2025.

Effect of revoking the administrative arrangement

As a result of the revocation, dentists will no longer be able to apply the administrative arrangement. Dentists who are following the administrative arrangement may continue to apply the administrative arrangement until the end of their current fiscal year. The revocation of the arrangement will apply to any fiscal year of the dentist that begins on or after January 1, 2025. A dentist who did not follow the administrative arrangement cannot apply it retroactively.

Dentists will be required to follow the same rules for claiming ITCs that GST/HST registrants must follow. The revocation of the administrative arrangement should not change the total amount of ITCs that a dentist who followed the administrative arrangement will be eligible to claim in a fiscal year. Under the arrangement, a dentist estimated their ITC eligibility and performed an end-of-fiscal-year reconciliation. The reconciliation ensured that the dentist’s ITC claims reflected the extent that the inputs were actually consumed or used in the course of their commercial activities. After the revocation of the arrangement, a dentist is expected to claim ITCs throughout the year based on their actual eligibility to do so without making estimates. The eligibility to claim an ITC for a particular input remains dependant on the extent that the input was acquired for consumption or use in the course of their commercial activities.

Input tax credit rules

A GST/HST registrant is generally eligible to claim an ITC for the GST/HST paid or payable on a property or service it acquired to the extent that the property or service was acquired for consumption or use in the course of the registrant’s commercial activities. A property or service is generally acquired for consumption or use in the course of a registrant’s commercial activities based on the extent to which the property or service is acquired for the purpose of making taxable supplies for consideration. Commercial activities include making taxable cosmetic service supplies or zero-rated supplies of orthodontic appliances for a fee. The making of exempt supplies, such as orthodontic services, is not a commercial activity for GST/HST purposes.

A GST/HST registrant dentist cannot claim an ITC for the GST/HST paid or payable on property or a service if the dentist acquires it for consumption or use substantially all (90% or more) in the course of the dentist’s exempt activities, such as making supplies of orthodontic services. Conversely, a dentist may generally claim an ITC equal to 100% of the GST/HST paid or payable on property or a service if the dentist acquires it for consumption or use substantially all in the course of making taxable supplies for consideration, including zero-rated supplies of orthodontic appliances.

An ITC must generally be apportioned where the property or service is acquired, imported or brought into a participating province for consumption or use, directly or indirectly, for the purpose of a dentist making both taxable supplies for consideration and exempt supplies.

In the case of capital personal property, a dentist is only eligible for ITCs on the GST/HST paid or payable if the property is acquired by the dentist for use primarily (more than 50%) in their commercial activities. Where a dentist acquires, imports or brings capital personal property into a participating province for use more than 50% in their commercial activities, the dentist may be eligible for an ITC equal to 100% of the GST/HST paid or payable on the property if all other conditions for claiming an ITC are met.

In the case of capital real property, a dentist may be eligible to claim an ITC to the extent that the property is acquired for use in their commercial activities if all other conditions for claiming an ITC are met. No ITC is allowed if the capital real property is acquired for use 10% or less in commercial activities. An ITC equal to 100% of the GST/HST paid or payable may be claimed if the capital real property is acquired for use 90% or more in commercial activities.

Where the dentist is operating their dental practice as a sole proprietor, the dentist cannot claim an ITC if the capital real property is acquired primarily (more than 50%) for their personal use or that of a related individual.
