Introduction

Dental practices invest regularly in continuing education for their clinical and administrative teams — mandatory CE for registered dental hygienists, assistant upgrading courses, front desk training, software certification, and more. These are genuine business costs, and for a dental professional corporation, most of them are deductible — but the specifics matter.

The General Rule: Staff Training Is Deductible

Staff training and continuing education expenses paid by a corporation for its employees are generally deductible as business expenses under section 18(1)(a) of the Income Tax Act, provided they are incurred for the purpose of earning income from the business.

For a dental practice, this encompasses a wide range of staff development costs:

CE courses required for maintaining the registration of dental hygienists and dental assistants

Infection control and sterilisation recertification

Radiography certification and upgrading

Practice management software training (Dentrix, Tracker, Abeldent)

Front desk and patient communication training

WHMIS and workplace health and safety training

Where the training is directly related to the employee's current role and the corporation pays for it, the cost is a deductible payroll-adjacent expense.

When Staff Training Creates a Taxable Employee Benefit

Training paid by the employer that provides a primarily personal benefit to the employee — rather than a business benefit — may create a taxable employment benefit for the employee.

The CRA's general position is that where training is primarily for the benefit of the employer (maintaining the employee's skills for the current job, required by a regulatory body, or keeping pace with practice developments), it is not a taxable benefit to the employee.

Where training provides a significant personal benefit — a credential that is transferable and enhances the employee's market value well beyond their current role, particularly where the training is not required by the employer — the CRA may characterise all or part of the cost as a taxable employment benefit.

For most dental staff training — mandatory CE for hygienists, required certification renewals, software training for the practice's own systems — the training is primarily for the business benefit of the practice, and no taxable benefit arises.

Conferences and Travel for Dental Staff

Where the practice sends staff members to a dental conference or industry event — including covering registration, travel, and accommodation — the same business purpose test applies. If the conference is relevant to the employee's role and the corporation pays as a business expense, the cost is deductible without a taxable benefit arising, provided the primary purpose is professional development rather than personal leisure.

Documentation — conference registration receipts, agenda, and confirmation of attendance — should be retained in the same manner as any business expense.

GST/HST on Training Costs

Training and educational services provided in Canada may or may not be subject to HST depending on whether the provider is a GST/HST registrant and the nature of the service. Courses provided by regulated educational institutions may be exempt. Courses provided by private trainers or professional development companies are generally taxable.

Where the dental corporation pays HST on a staff training course, it may be entitled to an input tax credit to the extent the training relates to the corporation's taxable commercial activities (cosmetic services, product sales). Where the practice is exclusively exempt (OHIP-style exempt dental services), the HST on training costs is a non-recoverable cost.

The Owner Dentist's Own CE

The cost of the owner dentist's own continuing education is deductible by the corporation as discussed in Article 61 (in the physician context, but the principles are the same for dentists). The professional development expenses of the principal clinician are legitimate corporate expenses, subject to the same documentation and business purpose standards.

When to Speak With a CPA

For dental practices with significant annual training budgets — including multiple staff attending conferences or completing credential upgrading — a CPA can ensure these costs are claimed correctly and confirm whether any taxable benefit reporting is required.
