Personal Services Business Rules in Ontario: When Incorporating Doesn't Save Tax

Many Ontario consultants and contractors incorporate expecting an automatic tax win. Sometimes it works out that way — and sometimes the Canada Revenue Agency looks at the arrangement and decides the corporation is not really running a business at all. When that happens, the corporation can be reclassified as a personal services business, and most of the tax advantage of incorporating disappears.

This is one of the more misunderstood corners of Ontario corporate tax planning. The label doesn't turn on how the paperwork is written; it turns on the substance of the working relationship. Understanding the test — and its narrow exceptions — matters before you incorporate, not after CRA reassesses you.

What Makes a Corporation a "Personal Services Business"?

A personal services business (PSB) exists, broadly, when an individual performs services through a corporation but would — if the corporation didn't exist — reasonably be regarded as an employee of the person or company paying for those services. CRA calls this person an "incorporated employee."

The corporation is real. The contract is real. But if the working relationship looks like employment in substance, the Income Tax Act treats the income the same way it would treat a disguised employment arrangement, regardless of the corporate wrapper around it.

The Test Looks at Substance, Not Labels

CRA and the courts weigh the same factors used generally to distinguish employees from independent contractors:

• Control — who directs how, when, and where the work gets done
• Ownership of tools — who supplies the equipment and workspace
• Chance of profit / risk of loss — whether the corporation can genuinely profit or lose money on the engagement, beyond simply being paid for hours worked
• Integration — how deeply the individual is woven into the payer's organization (a company email address, attendance at staff meetings, ongoing supervision)

No single factor decides the outcome. CRA looks at the whole relationship, and a written independent-contractor agreement doesn't override what actually happens day to day.

The Narrow Exceptions

A corporation that would otherwise look like a PSB can escape the label in two situations:

1. It employs more than a small number of full-time staff throughout the year in the business — a bright-line employee-count test built into the Income Tax Act.
2. It provides services to a corporation associated with the payer rather than to an arm's-length client.

Outside these two exceptions, a single incorporated consultant working long-term for one client, under that client's day-to-day direction, is squarely in PSB territory.

Why the Label Is Expensive

PSB status strips away the two things that make incorporating attractive for a small operating business:

The combined effect is a corporation that pays more tax on that income than a genuine small business would, while also losing most of its expense deductions. Confirm current federal and Ontario corporate rates with your accountant before relying on any specific figure — they change and this article won't quote them.

Situations That Raise PSB Risk

Watch for these patterns, which don't guarantee PSB status but tend to attract CRA's attention:

• [ ] One client accounts for essentially all of the corporation's revenue, year after year
• [ ] The client sets your hours, location, and supervises your day-to-day work
• [ ] The client provides your laptop, software licences, or workspace
• [ ] You were an employee of the same organization immediately before incorporating
• [ ] You have no realistic ability to profit beyond being paid for time worked
• [ ] You function like part of the client's internal team rather than an outside vendor

Reducing the Risk

• Build and maintain more than one client relationship where possible
• Negotiate contract terms that preserve genuine independence over methods and schedule
• Own and use your own equipment and tools where practical
• Keep records that document the business risk you actually carry
• Have a professional review the relationship periodically, especially before renewing a long single-client engagement
