Personal Services Business Rules: When An Incorporated Consultant Loses Small Business Tax Rates

A consultant leaves a full-time role, incorporates, and continues doing effectively the same work for the same client under a services agreement instead of an employment contract. This is one of the most common paths into incorporation, and one of the most common ways to accidentally trigger Canada's Personal Services Business rules.

What A Personal Services Business Actually Is

A Personal Services Business exists where an individual performs services on behalf of a corporation, and that individual, or a person related to them, would reasonably be regarded as an employee of the entity receiving the services if the corporation did not exist, unless the corporation employs more than five full-time employees throughout the year or the services are provided to an associated corporation[1].

The Employee Test CRA Actually Applies

CRA applies the same general employee-versus-contractor factors used elsewhere in tax law: the degree of control the client exercises over how and when the work is performed, whether the individual provides their own tools and equipment, whether there is a genuine chance of profit or risk of loss, and the degree of integration into the client's own organization[2]. A consultant working exclusively for one client, on that client's premises, using the client's equipment, under the client's direct supervision, closely resembles an employee regardless of the incorporated structure sitting on top of the relationship.

The Tax Consequences Of PSB Classification

The consequences of PSB classification are considerably more severe than simply losing the small business deduction. A Personal Services Business is also denied most ordinary business expense deductions, generally limited to the salary and benefits paid to the incorporated employee and certain other narrow costs, and is taxed at the full corporate rate on remaining income with no small business rate available at all[1]. The combined effect frequently produces a higher total tax burden than if the individual had simply remained a direct employee of the client, precisely the outcome the rules are designed to prevent being avoided through incorporation.

The Fact Patterns That Trigger It Most

• A single client relationship, especially one that mirrors a former employment role with the same organization.
• Client-directed schedule and location, working specific hours at the client's office using the client's equipment.
• No genuine business risk, guaranteed payment regardless of outcome, with no ability to profit beyond agreed fees or bear a loss on the engagement.
• Long-term, indefinite engagements that read more like ongoing employment than a defined project or genuine multi-client practice.

Reducing The Risk

The most direct way to reduce PSB risk is to structure the relationship, and actually operate it, in a way that reflects genuine independent contracting: multiple clients rather than one, control over how and when work gets done, use of the consultant's own equipment and workspace where practical, and defined, project-based engagements rather than open-ended ongoing arrangements. Documentation matters, but substance matters considerably more, a contract that describes independent contracting while the actual working relationship looks like employment does not resolve the underlying risk.
