One of the most consequential decisions a Canadian business owner makes when growing their team is whether to hire an employee or engage an independent contractor. The distinction has significant tax implications — for both the business and the worker — and the CRA takes worker misclassification very seriously. At BOMCAS Canada, our Professional Tax Accountants and payroll specialists help small and medium-sized businesses across Edmonton and all of Canada navigate these rules correctly.
Key Differences: Employee vs. Contractor
| Factor | Employee | Independent Contractor |
|---|---|---|
| Control over work | Employer controls how, when, and where | Controls their own methods |
| Tools and equipment | Provided by employer | Provides their own |
| Financial risk | No financial risk | Bears risk of profit/loss |
| Integration | Integral part of the business | Operates independently |
| Exclusivity | Usually works for one employer | Can work for multiple clients |
| Benefits | Entitled to vacation pay, benefits | No entitlement to benefits |
| Tax slip | T4 | T4A (if unincorporated) |
CRA Tests for Worker Classification
The CRA uses a four-factor test to determine whether a worker is an employee or an independent contractor. No single factor is determinative — the CRA considers the total relationship between the parties.
1. Control
Does the payer control not just what work is done, but how it is done? Employees are subject to direction and supervision. Independent contractors control their own methods and processes.
2. Ownership of Tools and Equipment
Who provides the tools, equipment, and workspace? Employees typically use tools provided by the employer. Independent contractors typically use their own tools and may have their own office or workspace.
3. Chance of Profit and Risk of Loss
Can the worker profit from good management of their work, or lose money if they manage it poorly? Employees receive a fixed wage with no financial risk. Independent contractors can profit from efficiency and bear the risk of loss.
4. Integration
Is the worker's activity an integral part of the payer's business, or is it accessory to it? Employees are integrated into the business. Independent contractors provide services that are ancillary to the business's core operations.
The CRA also considers whether there is a written contract, whether the worker can subcontract the work, and whether the worker has an opportunity to build equity or goodwill in their own business.
Payroll Obligations for Employees
When you hire an employee, you take on significant payroll obligations. As an employer, you must:
- Register a payroll account with the CRA
- Withhold income tax from each paycheque based on the employee's TD1 forms
- Withhold and remit the employee's CPP contributions and pay the employer's matching CPP contribution
- Withhold and remit the employee's EI premiums and pay the employer's EI premium (1.4 times the employee's premium)
- Issue T4 slips to all employees by the last day of February each year
- File a T4 Summary with the CRA
- Comply with provincial employment standards (vacation pay, overtime, statutory holidays, etc.)
Our Payroll Services team at BOMCAS Canada handles all of these obligations for businesses across Edmonton and Alberta, ensuring accurate and timely remittances every pay period.
Obligations When Hiring Contractors
When you engage an independent contractor, your obligations are significantly simpler:
- Pay the contractor the agreed fee — no withholding required
- Issue a T4A slip if you pay an unincorporated contractor more than $500 in a calendar year
- No CPP or EI obligations (the contractor is responsible for their own)
- No vacation pay, benefits, or employment standards obligations
If the contractor operates through a corporation, you pay the corporation directly and generally do not need to issue a T4A.
Risks of Misclassification
Misclassifying an employee as an independent contractor is one of the most costly mistakes a Canadian business owner can make. If the CRA determines that a worker you treated as a contractor is actually an employee, the consequences can be severe:
- You will owe all unremitted income tax that should have been withheld from the worker's pay
- You will owe the employer's share of CPP for all years in question
- You will owe the employer's share of EI premiums (1.4 times the employee's premiums) for all years in question
- You will owe interest and penalties on all amounts owing
- The CRA can reassess up to three years back (or longer if there was misrepresentation)
The financial exposure can be enormous, particularly for businesses that have engaged multiple workers as contractors over many years. It is critical to get the classification right from the start.
T4 vs. T4A: Which Slip to Issue
The type of information slip you issue depends on the worker's classification:
- T4 (Statement of Remuneration Paid): Issued to employees. Shows employment income, income tax withheld, CPP contributions, and EI premiums. Must be issued by the last day of February.
- T4A (Statement of Pension, Retirement, Annuity, and Other Income): Issued to unincorporated independent contractors for fees paid. Must be issued by the last day of February if total payments exceed $500.
Issuing the wrong slip — or failing to issue a required slip — can trigger CRA penalties and a review of your worker classification practices.
Personal Services Business Warning
If an incorporated contractor provides services exclusively to one client, the CRA may classify the contractor's corporation as a Personal Services Business (PSB). A PSB is taxed at a much higher rate than a regular corporation (the small business deduction is denied), and the contractor cannot deduct most business expenses. This is a significant tax trap for both the contractor and the client business.
The PSB rules apply when the incorporated contractor would be considered an employee of the client if not for the existence of the corporation. If you are engaging incorporated contractors who work exclusively for you, consult with a Corporate Tax Accountant at BOMCAS Canada to assess your exposure.
Frequently Asked Questions
How does the CRA determine if a worker is an employee or an independent contractor?
The CRA uses a multi-factor test examining control, ownership of tools, chance of profit and risk of loss, and integration. No single factor is determinative — the CRA looks at the total relationship between the parties.
What are the tax consequences of misclassifying an employee as a contractor in Canada?
The employer can be held liable for all unremitted CPP contributions, EI premiums, and income tax withholdings, plus interest and penalties. The CRA can reassess multiple years and the financial exposure can be substantial.
Do I need to issue a T4 or T4A to my workers?
Employees receive a T4. Unincorporated independent contractors who receive more than $500 in fees receive a T4A. If the contractor operates through a corporation, no T4A is required.
What is the difference between payroll obligations for employees vs. contractors?
For employees, you must withhold and remit income tax, CPP (both shares), and EI (both shares). For independent contractors, you have no withholding obligations — the contractor handles their own taxes and CPP.

How the CRA Determines Worker Classification
The CRA uses a multi-factor test to determine whether a worker is an employee or an independent contractor. No single factor is determinative — the CRA looks at the overall relationship between the parties. The key factors include: control (does the payer control how and when the work is done?), tools and equipment (who provides the tools?), subcontracting or hiring assistants (can the worker subcontract the work?), financial risk (does the worker risk their own money?), and opportunity for profit (can the worker profit from good management of the work?).
The CRA also considers the intention of the parties as expressed in their written contract, though intention alone is not sufficient if the actual working relationship contradicts it. If you are unsure about the classification of a worker, you can request a ruling from the CRA using Form CPT1. BOMCAS Canada's corporate tax team can help you review your worker arrangements and ensure proper classification before the CRA raises the issue.
Consequences of Worker Misclassification
Misclassifying an employee as an independent contractor is one of the most costly mistakes a Canadian business can make. If the CRA determines that a worker classified as a contractor is actually an employee, the business will be assessed for all CPP contributions and EI premiums that should have been deducted and remitted, plus the employer's share, plus interest and penalties. The assessment can go back several years, resulting in a very large unexpected tax bill.
In addition to the CRA assessment, the worker may have claims under provincial employment standards legislation for unpaid vacation pay, overtime, and other statutory entitlements. Directors of the corporation can be held personally liable for unremitted payroll deductions. To protect your business, always have a written contractor agreement, ensure contractors work for multiple clients, and review your arrangements with a professional accountant at least annually.
