When the Canada Revenue Agency reclassifies a worker from contractor to employee (or vice versa), it can significantly change how much tax you owe, what deductions you can claim, and whether you're entitled to employment benefits. The difference comes down to how each status treats income, deductions, and mandatory contributions. In 2026, understanding the financial impact of misclassification is critical because the CRA has been increasingly auditing gig workers and independent contractors to verify their actual status. The CRA doesn't just care about labels. They look at the actual relationship between you and the person paying you. A contractor enjoys more independence, sets their own hours, and can work for multiple clients. An employee, by contrast, works under someone else's control, follows a set schedule, and typically works exclusively for one employer. When the CRA suspects misclassification, they may: Demand back taxes, including unpaid payroll deductions Apply interest charges on any amount owed Assess penalties for non-compliance Reclassify your income retroactively (sometimes going back several years) The stakes are real. A contractor earning $60,000 per year might owe significantly more in taxes than an employee earning the same amount, but for different reasons.
You may owe back income tax on any business expenses you deducted, back CPP or EI contributions (depending on what you paid), plus interest. The CRA typically assesses back 4 to 6 years unless they suspect fraud, in which case it can go further. Penalties may also apply if the misclassification was wilful.
Yes. You can file Form CPT1 (Request for a Determination of Employment Status) with the CRA and request a formal ruling. Once the CRA issues a written decision, you're protected from penalties if you follow that ruling, even if your circumstances change later.
Possibly. Contractor CPP contributions are higher than employee CPP contributions because you pay both halves. If the CRA determines you should have been an employee, you may qualify for a refund on the overpaid employer portion, though this depends on when the reclassification is made.
The CRA looks at both. They examine written agreements, but more importantly, they assess the actual control, tools, risk, and integration of your work. Even if a contract says 'contractor,' the CRA may reclassify you if you work like an employee (fixed hours, employer provides tools, single client, employer directs your work).
The amount depends on your income level, how many deductions you claimed as a contractor, and your province. Generally, losing contractor deductions can increase your taxable income by 15% to 25%, which translates to a tax bill of $3,000 to $8,000 over two years for someone earning $60,000. Interest and penalties add to this amount.
