Personal Services Business Rules in Canada: Why Incorporated Contractors Need to Be Careful
Incorporated contractor in Canada? Ottawa CPA Majdi Ibrahim explains personal services business rules, PSB tax consequences, and how to assess your risk.
By Majdi Ibrahim, CPA | Majdi Ibrahim, CPA Professional Corporation | Ottawa, Ontario
Incorporating is one of the most common steps an independent contractor takes — and for good reason. The tax deferral benefits, the ability to control the timing of personal income, and the potential to retain earnings inside the corporation can make incorporation genuinely worthwhile.
But there's a classification that can strip all of those benefits away: the Personal Services Business (PSB).
If CRA determines that your corporation is a PSB — that you're effectively an "incorporated employee" rather than a genuine independent business — the corporation loses the small business deduction, loses access to most ordinary business deductions, and is taxed at a much higher corporate rate. The tax advantage of incorporating disappears almost entirely.
This isn't a theoretical risk. CRA launched a PSB pilot in 2022 focused on outreach, education, and compliance awareness. Budget 2025 proposes funding for a focused program addressing PSB-related non-compliance and reporting fees for service. Ottawa's contractor community — heavily concentrated in government and tech — is exactly the type of environment where PSB risk is real and worth understanding.
At a Glance
A Personal Services Business is a corporation that provides the services of an "incorporated employee." If the corporation didn't exist and the individual provided their services directly, they would reasonably be considered an employee of the client — not an independent contractor.
The consequences are significant. A PSB loses the small business deduction, the general rate reduction, and most ordinary business deductions. Corporate tax rates jump substantially.
PSB determination is fact-specific. No single factor determines PSB status. CRA looks at the actual working relationship, not just the contract.
A written contract doesn't solve the problem on its own. CRA and the courts look through the form of the arrangement to the substance of how services are actually provided.
Ottawa government contractors should pay particular attention. These arrangements can include several PSB risk factors: one client, long-term placement, client direction, use of client systems, and integration with the client's team.
What Is a Personal Services Business?
A Personal Services Business is defined in subsection 125(7) of the Income Tax Act. A corporation generally carries on a PSB where:
- An individual performs services through the corporation — this person is called the "incorporated employee"
- The incorporated employee (or a related person) is a specified shareholder — generally meaning they own at least 10% of the corporation's shares directly or indirectly
- If the corporation did not exist, the incorporated employee would reasonably be considered an employee of the entity receiving the services
- The corporation does not employ more than five full-time employees throughout the taxation year
- The amounts received are not from an associated corporation
The fifth condition — the associated-corporation exclusion — is worth noting briefly: the PSB rules are generally aimed at incorporated individuals providing services to arm's-length clients, not ordinary services provided within an associated corporate group.
The third condition is the heart of the analysis — and it's also the most fact-intensive. Whether the incorporated employee "would reasonably be considered an employee" depends on the actual nature of the working relationship, not on what the contract says.
The five-employee exception: If the corporation employs more than five full-time employees throughout the year, the PSB conditions are not met and the corporation generally won't be classified as a PSB regardless of the other factors. For most sole-contractor operations, this exception doesn't apply.
How CRA Assesses the Working Relationship
Because the third condition requires a judgment about the nature of the relationship, CRA applies the same tests used in employment law to distinguish employees from independent contractors. These tests come from decades of court decisions, and they look at substance over form.
Control. How much does the client control how, when, and where the work is done? If the contractor follows the client's schedule, works at the client's location, uses the client's processes and systems, and can't subcontract or delegate the work, these all point toward employment.
Tools and equipment. Does the contractor use their own tools, equipment, and technology — or does the client provide everything? Using the client's computers, systems, and workspace consistently is an employment indicator.
Financial risk and opportunity for profit. A genuine independent contractor has the possibility of making more money by being efficient or less money if things go wrong — and bears the risk of business expenses. An incorporated contractor who receives a fixed hourly or daily rate, works set hours, and has no meaningful business exposure of their own looks more like an employee.
Integration into the client's business. Is the work integral to the client's core business operations, performed alongside employees doing similar work? Or is the contractor providing a distinct, specialized service that the client's own workforce doesn't do? The more integrated the work, the more it resembles employment.
Exclusivity and dependence. Having one main client who provides the vast majority of revenue is a significant PSB risk factor. A genuine independent business typically has (or is seeking) multiple clients. A corporation that exists solely to service one client and bills nowhere else looks like a corporate wrapper on an employment relationship.
What a contract says matters — but doesn't control the outcome. CRA and the courts regularly look past the form of the arrangement to how the relationship actually operates. A contract calling someone a "contractor" with full independence doesn't determine PSB status if the facts on the ground show employment-like conditions.
The Tax Consequences of PSB Classification
No small business deduction. The corporation can't apply the small business rate to its income. The main tax benefit of incorporating — the significantly lower corporate rate on active business income — disappears.
No general rate reduction. PSBs are also excluded from the general rate reduction that applies to most other corporate income.
Higher effective corporate tax rate. Federally, PSB income is taxed at 28% after the federal abatement (the basic federal rate of 38% less 10% abatement), plus an additional 5% tax introduced in 2016, for a combined federal rate of 33%. In Ontario, the combined corporate tax rate on PSB income has commonly been described as approximately 44.5%, made up of the federal rate after abatement, the additional 5% federal PSB tax, and Ontario corporate tax. By comparison, income eligible for the small business rate is taxed at a much lower combined rate — though rates should be confirmed for the relevant year.
Severely limited deductions. A PSB can generally only deduct:
- Salary, wages, or remuneration paid to the incorporated employee
- Benefits or allowances provided to the incorporated employee
- Certain selling or contract-negotiation expenses that would have been deductible if the individual were an employee under an employment contract requiring those expenses
- Legal expenses incurred to collect amounts owed for services rendered
That's it. The broad range of business expenses available to most corporations — office costs, equipment, professional development, business insurance, and similar items — are generally not deductible for a PSB.
Common PSB Risk Scenarios
The IT consultant working exclusively for one federal department. They work on-site, use government systems, attend government meetings, and follow the department's direction. The contract says "independent contractor." The facts say otherwise.
The finance contractor placed through a staffing agency. They work full-time hours at the client's location, are supervised by client management, and have been doing the same work for the same client for three years. There are no other clients, no business development activities, and no real financial risk.
The project manager at a construction company. They incorporated because the company required it, use the company's equipment, follow the company's schedule, and have no other clients. The incorporation doesn't change the substance of the relationship.
What these situations have in common: one main client, client control over how and when work is done, little or no independent business presence, no meaningful risk of profit or loss beyond the fixed rate. None of these is automatically a PSB — the analysis is always fact-specific. But each presents significant risk factors that a CPA should review before the situation is assessed by CRA rather than after.
Why Ottawa Government Contractors Should Pay Particular Attention
Ottawa government contractors should pay particular attention because these arrangements can include several PSB risk factors: one client, long-term placement, client direction, use of client systems, and integration with the client's team. This doesn't mean Ottawa contractors are assumed to be PSBs — the analysis is always fact-specific. But these are exactly the factors CRA considers, and the combination that often characterizes government contracts makes a proper PSB review worthwhile at incorporation and with each new contract.
A CPA conversation upfront is a much better investment than a reassessment several years after the fact. We discuss the broader question of whether incorporation makes sense in our incorporation guide.
What Doesn't Solve PSB Risk
Having a written contract that says "independent contractor" doesn't determine status. CRA looks at the actual working relationship — how the work is done, who controls it, what risk exists. The label in a contract is relevant but not determinative.
Incorporating doesn't establish independent contractor status. The PSB rules exist specifically because incorporation doesn't change the underlying nature of the working relationship. The Tax Court has repeatedly found PSBs despite the presence of a corporation.
Registering for GST/HST doesn't confirm independent contractor status. Contractors should register for GST/HST once revenues exceed the threshold regardless of employee/contractor classification. Being registered doesn't resolve the PSB question.
One factor alone doesn't determine the outcome. Having one client isn't automatically a PSB. Working on-site isn't automatically a PSB. CRA looks at the totality of the circumstances. The risk increases as more factors point toward the employment side of the spectrum.
What Actually Helps — and Its Limits
Certain factual characteristics genuinely support an independent contractor position:
- Multiple clients — servicing more than one client is one of the strongest indicators of independent business activity
- Setting your own schedule and methods — genuine control over how, when, and where work is performed
- Using your own tools, equipment, and systems — not relying on the client's infrastructure
- Having real financial risk — bearing the cost of business expenses, the possibility of not getting paid, or the financial risk of a fixed-price contract
- Maintaining an independent business presence — a website, separate business address, marketing activity, professional memberships, or other indicators of carrying on a genuine business
- A well-drafted services agreement — one that describes the relationship accurately, not just labels it "independent contractor"
These factors can strengthen the position — but they need to be real, not cosmetic. A contract that says the contractor can subcontract work doesn't help much if the work has never actually been subcontracted and the client wouldn't permit it.
What to Do if You're Already Incorporated and Concerned
If you're reading this and recognizing your own situation, the appropriate first step is a frank assessment of the actual risk — ideally with a CPA who understands PSB rules.
If the risk is real and the corporation's past filings have been done on the assumption it's an active business (claiming the small business deduction and ordinary business deductions), there may be an exposure on prior years. Depending on the circumstances, this could be a situation where the Voluntary Disclosures Program is relevant — coming forward before CRA contacts you about those specific filings can significantly affect the outcome. We cover that in detail in our behind on taxes and VDP article.
If the corporation hasn't yet been filing as a PSB but the working relationship warrants review, the options might include restructuring the working arrangements (genuinely, not cosmetically), considering whether salary is the most appropriate form of compensation from the corporation, or accepting the PSB status and managing accordingly.
What Happens When You Bring This to Majdi Ibrahim, CPA?
An honest PSB risk assessment. We review your actual working arrangements — the contract, the day-to-day reality, the client relationship — and give you an informed view of where the risk sits, without sugarcoating it.
Practical advice, not just a warning. If PSB risk is real, we help you understand what that means for your current and prior filings, what options exist, and what — if anything — can be genuinely (not cosmetically) improved.
Filing and catch-up support if needed. If prior years need to be addressed, we help navigate the options, including whether VDP or catch-up filing makes sense given the specific circumstances.
Ongoing review as your contracts change. PSB risk can change with each new contract or client. We review the question whenever it's relevant — not just once at incorporation.

Frequently Asked Questions
What is a Personal Services Business in Canada?
A Personal Services Business is a corporation that provides the services of a shareholder who, if the corporation didn't exist, would reasonably be considered an employee of the client. The definition is in subsection 125(7) of the Income Tax Act and requires meeting several conditions — the individual is a specified shareholder, the corporation employs five or fewer full-time employees, the amounts are not from an associated corporation, and the incorporated employee would reasonably be considered an employee of the payer if the corporation did not exist. The associated-corporation exclusion means the rules are aimed at arm's-length service arrangements, not ordinary services within an associated corporate group. The core question is whether the working relationship looks more like employment than independent business, assessed on the actual facts.
What are the tax consequences of being classified as a PSB?
A PSB loses the small business deduction and the general rate reduction, and is subject to an additional 5% federal tax on PSB income. The corporation can generally only deduct salary paid to the incorporated employee, related benefits, certain selling and contract-negotiating expenses, and legal fees for collection. In Ontario, the combined corporate tax rate on PSB income has commonly been described as approximately 44.5%, made up of the basic federal rate after abatement, the additional 5% federal PSB tax, and Ontario corporate tax — rates should be confirmed for the relevant year. By comparison, income eligible for the small business rate is taxed at a much lower combined rate.
Does having a written independent contractor agreement protect me from PSB classification?
No. CRA and the Tax Court look through the form of the arrangement to the actual working relationship — who controls the work, who provides the tools, whether there is real financial risk, and how integrated the contractor is into the client's business. A contract labelling the arrangement as independent contracting is relevant but not determinative. The facts on the ground matter more.
I only have one client — does that automatically make me a PSB?
Not automatically. Having one client is a significant risk factor — it's consistent with employment-like financial dependence — but PSB determination is always fact-specific. A contractor with one client might still be genuinely independent if they control how they work, use their own tools, bear real financial risk, and the arrangement looks like independent contracting in substance. But one client with employment-like conditions is exactly the scenario CRA scrutinizes, and the risk should be assessed properly.
What deductions can a PSB claim?
A PSB can generally only deduct salary, wages, or remuneration paid to the incorporated employee, benefits and allowances provided to them, certain selling or contract-negotiating expenses that would have been deductible under an employment contract requiring those expenses, and legal fees for collecting amounts owed. Ordinary business expenses such as office costs, equipment, professional development, and business insurance are generally not deductible for a PSB.
Does incorporating help Ottawa government contractors with taxes?
It can, but the PSB risk needs to be assessed first. Ottawa government contracting arrangements can include several PSB risk factors: one client, long-term placement, client direction, use of client systems, and integration with the client's team. Whether the benefits of incorporating outweigh the PSB risk depends on the actual working conditions of the specific contract, and the analysis is always fact-specific.
If I think I might be a PSB but haven't been filing that way, what should I do?
Speak to a CPA before doing anything else. The options depend on the specific facts, how many years are involved, and whether CRA has already been in contact about the issue. In some situations, the Voluntary Disclosures Program may be available to address prior filings with reduced penalties and interest. Acting earlier generally creates better options than waiting.
