Common Mistakes to Avoid

Underestimating Deductions

Many independent contractors overlook eligible deductions, which can significantly reduce their taxable income. Make sure to include all business-related expenses.

Ignoring Tax Brackets

Ontario's tax system uses progressive brackets. If you earn more, you'll pay a higher percentage on that additional income. The calculator helps you see how different income levels affect your taxes.

Forgetting CPP and EI

As an independent contractor, you're still required to pay CPP and EI contributions. The calculator includes these in your net earnings calculation.
