Personal Services Business (PSB): What It Is, Why the CRA Is Watching, and How to Protect Your Corporation

You incorporated to keep more of what you earn. But if the Canada Revenue Agency decides your corporation is a Personal Services Business, that decision can be reversed almost overnight — and the back taxes, interest, and penalties can be devastating. We’ve seen incorporated drivers and contractors hit with reassessments that wiped out years of savings, simply because their setup looked, on paper, like employment.

The good news is that the rules are knowable, and most of the risk is manageable once you understand how the CRA thinks. This guide explains what a Personal Services Business is, how the CRA taxes one, who gets flagged most often (truckers, we’re looking at you), how to stay on the right side of the line, and exactly what to do if a PSB notice lands in your mailbox.

What Is a Personal Services Business?

A Personal Services Business — usually shortened to PSB — is the CRA’s term for a corporation that is really just an employee in disguise. The technical phrase the Income Tax Act uses is “incorporated employee.” In plain language: you set up a corporation, but the way you actually work looks no different from being on a company’s payroll.

The CRA’s core test is a simple thought experiment. If your corporation didn’t exist, would you reasonably be considered an employee of the company you provide services to? If the honest answer is yes, you’re at risk of being treated as a PSB.

Under the law, your corporation can be classified as a PSB when all of these are true (CRA: Determine if your corporation is carrying on a PSB):

• An individual (the “incorporated employee”) performs the services on the corporation’s behalf.
• That individual — or someone related to them — owns 10% or more of the corporation (a “specified shareholder”).
• Without the corporation, that individual would reasonably be regarded as an employee of the business receiving the services.
• The corporation does not employ more than five full-time employees throughout the year, and the income is not earned from an associated corporation.

That last point is important: employing more than five full-time staff is a built-in exception. Most one- and two-person corporations don’t come close, which is exactly why they draw scrutiny.

How the CRA decides whether you’re “really” an employee

To answer the employee-versus-contractor question, the CRA leans on long-established factors:

• Control — Does the payer dictate your hours, your routes, your methods, and how the work gets done? More control points toward employment.
• Tools and equipment — Do you supply your own major equipment, or does the payer provide it?
• Chance of profit and risk of loss — Can you actually profit from running your business well, and can you lose money if it goes badly? Genuine businesses carry financial risk.
• Integration and independence — Are you free to take on other clients, subcontract work, and run your own operation, or are you woven into one company like a staff member?

No single factor decides it. The CRA looks at the whole picture.

How the CRA Treats a PSB: Why the Tax Bill Hurts

This is where PSB status stops being a label and starts costing real money. A normal Canadian-controlled private corporation gets two big breaks: the small business deduction (SBD) and the general rate reduction. A PSB gets neither — and then gets penalized on top.

Here’s what happens to PSB income:

1. No small business deduction. The low small-business tax rate is gone.
2. No general rate reduction. The standard corporate rate cut that other corporations enjoy doesn’t apply either.
3. An extra 5% federal PSB tax. On top of losing those breaks, PSB income carries an additional 5% federal tax, pushing the federal rate to 33% (CRA: What is a personal services business).
4. Severely restricted deductions. This is the part that catches owners off guard.

Add federal and provincial rates together and the gap is stark. In Ontario, a corporation eligible for the small business deduction pays roughly 12.2% combined on that income. A Personal Services Business in Ontario pays about 44.5% — the 28% federal rate, plus Ontario’s 11.5% general rate, plus the 5% PSB tax (CRA: Personal services business). That’s not a small adjustment; it can more than triple the tax on the same dollar of income.

The deduction trap most owners miss

As a PSB, your corporation generally cannot deduct ordinary business expenses like rent, advertising, supplies, or most travel. The Income Tax Act limits a PSB to deducting little more than:

• Salary, wages, and benefits paid to the incorporated employee;
• Certain expenses the incorporated employee could have claimed as a regular employee; and
• Costs of selling property or negotiating contracts.

So a PSB can lose the small business rate, get taxed at the full general rate plus 5%, and lose the write-offs it was counting on — often for several past years at once, with interest and penalties layered on. When the CRA reassesses more than one year, the result can be a tax shock that runs into tens of thousands of dollars.

Who Is Most at Risk of Being Flagged as a PSB?

The CRA’s own PSB pilot project found that potential PSBs cluster heavily in a handful of industries. If you recognize yourself below, pay close attention.

Incorporated truckers and owner-operators

Trucking is squarely in the CRA’s sights, and it’s the number-one PSB question we get. Here’s why owner-operators get flagged so often: many trucking companies push drivers to incorporate before they’ll give them work. The motivation is usually to avoid the payer’s share of CPP and EI, overtime, vacation pay, and the paperwork of having an employee. But if you then drive exclusively for that one company, on their schedule and largely under their direction, you look exactly like an employee who happens to have a corporation — the textbook PSB.

This is no longer a quiet issue. Recent federal budget measures specifically target worker misclassification in the trucking industry, including expanded information-sharing between the CRA and Employment and Social Development Canada. If you’re an incorporated driver working for a single carrier, your risk is rising, not falling.

Other high-risk profiles

• IT consultants and software contractors who bill one client through their corporation, often on long-term contracts that resemble full-time roles.
• Trades and construction contractors who work primarily for one general contractor or builder.
• Professionals and consultants — engineers, project managers, marketers, and similar — who left a job and came back to do the same work through a corporation for the same employer.
• Anyone working mainly for one payer while functioning like a member of their team.

The common thread isn’t your industry — it’s whether you operate like a genuine, independent business or like an employee with a numbered company.

How to Avoid Being Flagged as a PSB: A Practical Checklist

You can’t change what your work truly is, but you can make sure your structure and documentation reflect a real, independent business. Use this as a starting checklist:

• Work for more than one client. Relying on a single payer is the strongest PSB red flag. Diversifying your client base is the single most protective step.
• Control your own work. Set your own hours where possible, choose your own methods and routes, and avoid being supervised like staff.
• Supply your own tools and equipment. Owning the major assets you work with signals an independent operation.
• Take on genuine business risk. Quote fixed prices, carry your own insurance, and accept that you can profit or lose based on how you run things.
• Use proper contracts. A written contract for services — not an employment-style arrangement — that reflects an independent-contractor relationship matters. (A contract alone won’t save you if the facts say “employee,” but the wrong contract certainly hurts.)
• Invoice like a business. Issue professional invoices, register and charge GST/HST where required, and keep your billing separate and businesslike.
• Keep clean, complete records. Document your clients, contracts, equipment, marketing, and the day-to-day independence of your operation.
• Know the five-employee exception. A corporation that employs more than five full-time employees throughout the year generally falls outside the PSB rules — relevant if your business is genuinely scaling.

If your situation is borderline, this is the point to get advice before you file — not after a notice arrives.

What to Do If You Get a CRA Notice About PSB Status

Receiving a letter or reassessment from the CRA about PSB status is alarming, but how you respond matters enormously. Take a breath and work the steps:

1. Don’t ignore it. CRA notices carry deadlines. Missing them can cost you the right to object and lock in the assessment.
2. Don’t respond alone. Anything you say can shape how the CRA characterizes your relationship with the payer. A poorly worded reply can do real damage.
3. Gather your documentation. Pull together contracts, invoices, proof of multiple clients, equipment ownership, insurance, and anything showing your business operates independently.
4. Understand your rights. You generally have the right to provide additional information and, if you disagree with a reassessment, to file a formal Notice of Objection within the prescribed deadline.
5. Call a CPA right away. A professional can frame your facts correctly, communicate with the CRA on your behalf, and protect both your current return and prior years.

The earlier you bring in help, the more options you have.

A Real-World Example: The Incorporated Trucker

Consider “Mr. X,” an owner-operator who incorporated at his carrier’s request. His corporation has one client — the carrier — and Mr. X drives the routes and schedule they assign. He claimed the small business deduction and wrote off fuel, meals, his cell phone, and vehicle costs.

On review, the CRA concluded Mr. X would clearly be an employee of the carrier if his corporation didn’t exist: one payer, their schedule, their direction. It reassessed the corporation as a PSB. The small business deduction was denied, the income was taxed at the full general rate plus the 5% PSB tax, and most of his deductions were thrown out — across multiple years, with interest. A setup that was supposed to save tax ended up costing far more than staying an employee ever would have.

The painful part: with the right structure, documentation, and advice from the start, much of that exposure could have been managed.

Frequently Asked Questions About Personal Services Businesses

Is a PSB taxed higher in Canada? Yes — significantly. A PSB loses the small business deduction and the general rate reduction and pays an extra 5% federal tax, bringing the federal rate to 33%. Combined with provincial tax, the rate in Ontario is roughly 44.5%, compared to about 12.2% for income eligible for the small business deduction.

Can a one-person corporation be a PSB? Yes. In fact, one- and two-person corporations are the most common PSB profiles, because they rarely meet the “more than five full-time employees” exception and often serve a single client.

Why does the CRA target incorporated truckers? Carriers frequently require drivers to incorporate to avoid CPP, EI, and other employer costs. When an incorporated driver works for one carrier on the carrier’s terms, the arrangement looks like employment — the classic PSB pattern. Recent federal measures specifically target misclassification in the trucking industry.

What expenses can a PSB deduct? Very few. Generally only salary and benefits paid to the incorporated employee, certain expenses that employee could have claimed personally, and costs related to selling property or negotiating contracts. Most ordinary business write-offs are denied.

What should I do if I get a PSB notice from the CRA? Don’t ignore it and don’t respond alone. Gather your documentation, note the deadlines, and contact a CPA immediately so your facts are presented correctly and your objection rights are protected.
