Personal Services Businesses (PSBs) in Canada: What Every Incorporated Contractor Needs to Know

Many professionals choose to incorporate for the flexibility, liability protection, and potential tax advantages it offers. However, if the Canada Revenue Agency (CRA) determines that your corporation is a Personal Services Business (PSB), many of those tax advantages can disappear.

A PSB generally cannot claim the Small Business Deduction and is subject to a different corporate tax regime, often resulting in a significantly higher corporate tax bill.

If you're an IT consultant, truck driver and owner-operator, project manager, engineer, or other independent contractor working primarily for one client, understanding the PSB rules is essential.

What Is a Personal Services Business?

A Personal Services Business is a corporation that provides the services of an individual who would likely be considered an employee if the corporation didn't exist.

In other words, if your corporation simply invoices a client for work you perform under conditions similar to employment, the CRA may classify your business as a PSB.

Why Does PSB Status Matter?

A PSB does not qualify for many of the tax benefits available to other Canadian-controlled private corporations.

If your corporation is classified as a PSB, you could:

• Pay corporate tax at rates significantly higher than those available to qualifying active businesses, with combined rates potentially exceeding 40% in some provinces.

• Lose access to the Small Business Deduction.

• Face restrictions on the expenses your corporation can deduct.

  
  

Unlike an ordinary operating business, a PSB generally has limited deductible expenses. Deductions are typically restricted to salary paid to the incorporated employee and certain expenses specifically permitted under the Income Tax Act.

For many incorporated professionals, this can eliminate many of the tax advantages of incorporation.

How Does the CRA Determine PSB Status?

There is no single test. Instead, the CRA evaluates the overall working relationship using the Income Tax Act, principles established through Canadian court decisions, and its own administrative guidance. No single factor determines whether a corporation is a Personal Services Business.

Some of the key factors include:

Control. If the client determines how, when, and where you perform your work, the relationship may resemble employment.

Tools and equipment. Independent businesses typically provide and maintain their own equipment, software, and workspace.

Financial risk. Contractors usually incur business expenses and assume financial risk regardless of whether they are paid.

Opportunity for profit. An independent business can often increase profits by improving efficiency, hiring staff, or taking on additional clients.

Integration. The more your services are integrated into the client's business, the more likely the relationship resembles employment.

It's also important to remember that while a written contract matters, the CRA looks beyond the wording of the agreement and considers how the relationship actually operates in practice.

Common Situations That May Increase PSB Risk

While every case is different, certain working arrangements are more likely to attract CRA scrutiny. For example, you may face greater PSB risk if you work almost exclusively for one client, your contract is repeatedly renewed, you work regular hours under the client's supervision, use equipment provided by the client, perform duties similar to those of employees, or cannot hire someone else to perform the work.

Risk may also increase if your agreement prevents you from working for other clients or if you are treated in substantially the same way as employees of the client.

Is There an Exception?

Generally, a corporation will not be considered a Personal Services Business if it employs more than five full-time employees throughout the year. However, most incorporated contractors and independent professionals operate without that level of staffing, making the PSB rules particularly relevant.

Can You Avoid Being Classified as a PSB?

Although no structure guarantees a particular tax outcome, there are practical steps that may help demonstrate you're operating an independent business:

• Work with multiple clients whenever possible.

• Maintain your own website and actively market your services.

• Invest in your own equipment and software.

• Set your own work methods and schedule where practical.

• Negotiate contracts that reflect an independent business relationship.

• Carry business insurance.

• Accept some degree of financial risk and opportunity for profit.

  
  

These factors may strengthen the argument that your corporation operates as an independent business. However, none of them guarantees that CRA will accept the corporation’s position. The CRA will continue to assess the complete relationship between the parties.

Responding to a CRA PSB Review or Information Request

If CRA reviews your corporation’s PSB status, you may be asked to provide information about your working relationship with a client. A strong response should focus on how the business operates, supported by documentation such as contracts, invoices, business insurance, evidence of other clients, and records showing financial risk and independence.

A written agreement alone may not determine the outcome. CRA considers the facts of each situation, including the nature of the relationship and the responsibilities of each party. A complete response supported by relevant documentation is essential when addressing a CRA review.

What Happens If the CRA Reassesses You?

If the CRA determines that your corporation is a PSB, it may reassess previous tax years. Potential consequences include:

• Additional corporate tax.

• Interest on unpaid taxes.

• Possible penalties.

• Loss of access to certain corporate tax deductions.

  
  

CRA may also deny Small Business Deduction claims previously made and reassess deductions that would not be available to a PSB.

The financial impact can be substantial, especially if the reassessment covers multiple years.

Should You Still Incorporate?

Incorporation can still be an excellent choice for many professionals. It offers liability protection, flexibility in compensation planning, and tax deferral opportunities when structured appropriately.

However, incorporation should be based on your specific circumstances—not simply because a client requires it.

Before incorporating or accepting a long-term contract through your corporation, it's worth reviewing whether the arrangement could create PSB risk.

How an Accountant Can Help

The Personal Services Business rules depend on the specific facts of your working relationship, making them difficult to assess without professional advice. An experienced accountant can help you evaluate your PSB risk, identify potential issues, and recommend practical strategies to help you remain compliant and make informed decisions about your corporation.

An accountant can also assist if CRA reviews your corporation’s PSB status by helping gather relevant documentation, analyze the working relationship, and prepare a response that accurately reflects how the business operates in practice.
