If the CRA classifies your IT consultancy or contractor corporation as a Personal Services Business (PSB), your corporate tax rate can jump from the small business rate of 12.2% to a punishing 44.5% (in Ontario). Defending an audit involves proving you operate with genuine financial risk and true independence.
Many Canadians choose to incorporate their businesses to work as independent contractors, IT consultants, or freelance project managers. In major hubs like Toronto, Calgary, and Ottawa, forming a corporation provides access to the highly favourable Small Business Deduction (SBD), which lowers your corporate tax rate significantly. However, the Canada Revenue Agency (CRA) is intensely auditing these small corporations to see if they are actually “incorporated employees” in disguise. This trap is legally known as a Personal Services Business (PSB).
A PSB assessment is financially devastating. When the CRA reclassifies your corporation as a PSB, you lose all your small business tax benefits. Worse, the CRA denies almost all your business expense deductions-meaning you can no longer write off your home office, travel, or supplies. You are suddenly taxed at an extremely high rate and will likely face a massive reassessment for past years. If a CRA auditor comes knocking, you must be prepared to prove that your corporation is a genuine, independent business entity. Consulting a local tax lawyer from our directory can be a lifesaver in these disputes.
Step-by-Step Process for Fighting a PSB Audit in Canada
Defending against a PSB audit requires strong legal arguments and impeccable documentation. The CRA uses a multi-factor test established by the Tax Court of Canada to determine your status. Here is how you can fight back.
Step 1: Understand the CRA’s Four-Point Test
The auditor will evaluate your working relationship with your client using four main criteria: Control, Ownership of Tools, Chance of Profit/Risk of Loss, and Integration. You must analyze your situation. Do you set your own hours? Do you provide your own laptop and software? If you make a mistake, do you fix it on your own dime? Answering “yes” strengthens your defence as an independent contractor.
Step 2: Review Your Master Service Agreements
Your contracts are your first line of defence. Gather your Independent Contractor Agreements or Master Service Agreements (MSA). 📋 These contracts must explicitly state that you are an independent contractor, not an employee. However, the CRA will look past the contract to see the “reality” of your daily work. If your contract says you are independent, but your client forces you to attend mandatory staff meetings and wear a company badge, the CRA will rule against you.
Step 3: Document Your Financial Risk and Expenses
A true business takes on financial risk. You need to prove this to the auditor. Gather invoices showing you paid for your own training, liability insurance, software licenses, and marketing. Evidence that you hired a subcontractor to help you complete a project is one of the strongest ways to prove you are a legitimate business, not a Personal Services Business.
Step 4: Respond to the CRA Audit Questionnaire
The auditor will send you a detailed questionnaire about your daily operations. 📩 Do not fill this out hastily. The wording you use is critical. If you refer to your client as your “employer” or your project fee as your “salary,” you are handing the CRA ammunition. It is highly recommended to have a tax lawyer review your answers before submitting them.
Step 5: File a Notice of Objection
If the auditor decides you are a PSB and issues a Notice of Reassessment, you have exactly 90 days to fight it. You must file a formal Notice of Objection. At this stage, your tax lawyer will draft a detailed legal submission to the CRA Appeals Division, citing relevant case law from the Tax Court of Canada to overturn the auditor’s decision.
How Much Does a PSB Reassessment Cost?
A PSB ruling can bankrupt a small corporation. The costs are a mix of back taxes, lost deductions, and professional defence fees.
| Tax Impact / Fee Type | Estimated Cost (CAD) | Description |
|---|---|---|
| Loss of Small Business Rate | Varies (Approx 32% increase) | Your corporate tax rate rockets from ~12% to over 44% on all PSB income. |
| Denied Business Expenses | $5,000 – $20,000+ | The CRA will disallow your phone, travel, and home office deductions, adding to your tax bill. |
| Audit Representation Fees | $3,000 – $8,000 | Cost for a tax professional to handle the initial auditor questions and meetings. |
| Notice of Objection Legal Fees | $5,000 – $15,000 | Lawyer fees to formally dispute the reassessment at the appeals level. |
How Long Does the Process Take?
An initial PSB audit generally lasts between 6 to 12 months, depending on how quickly you provide documentation. ⏳ If the CRA reassesses your corporation and you file a Notice of Objection, you will enter a waiting period. It currently takes the CRA Appeals Division 12 to 24 months just to assign an Appeals Officer to your file. If the objection fails, appealing to the Tax Court of Canada adds another 2 to 3 years.
Frequently Asked Questions (FAQ)
What exactly is an incorporated employee?
An incorporated employee is someone who provides services through a corporation, but acts exactly like a normal employee. If you have a boss, strict working hours, and use the client’s equipment, the CRA views you as an employee hiding behind a corporate shell.
Am I automatically a PSB if I only have one client?
No. While having only one client is a red flag for the CRA, it is not an automatic fail. If you can prove you had the capacity to take on other clients, assumed financial risk, and controlled your own work schedule, you can still win a PSB dispute.
What expenses can a PSB deduct?
If classified as a PSB, you can only deduct the salary and benefits paid directly to the incorporated employee (you). You cannot deduct standard business expenses like travel, meals, home office costs, or accounting fees.
How far back can the CRA audit for a PSB?
The CRA can generally audit your corporate tax returns for the past three years. However, if they suspect gross negligence or deliberate misrepresentation, they can open up audits indefinitely.
Should I use my accountant or a tax lawyer for a PSB audit?
An accountant is great for filing your daily taxes, but a PSB audit is a legal dispute based on contract law and Tax Court precedents. Hiring a tax lawyer ensures your arguments are rooted in the law and protects your communications under solicitor-client privilege.
