Whether to incorporate your self-employed business is one of the biggest tax decisions you'll make. The short answer: incorporation can save you money on taxes if you earn over $50,000 annually, but it also adds accounting complexity and costs. The right choice depends on your income level, business structure, and long-term goals. Most sole proprietors benefit from incorporation eventually, but not always right away. When you're self-employed as a sole proprietor, all your business income flows directly to your personal tax return. You pay full income tax on every dollar earned, plus you're responsible for both the employer and employee portions of CPP contributions (about 9.9% combined in 2026). Incorporation creates a separate legal entity that earns income on its own, and this separation can trigger tax savings. The primary advantage is income splitting and tax deferral. When you incorporate, your business pays corporate tax (which is lower than personal income tax in most provinces), and you only pay personal tax on what you withdraw as salary or dividends. Money left in the corporation isn't taxed at your personal rate, allowing you to reinvest or save for retirement more efficiently.
This rule may apply to you: incorporation typically becomes tax-efficient when your net business income exceeds $50,000 to $60,000 annually. Below that threshold, the accounting and legal costs usually outweigh the tax savings. Your exact break-even point depends on your province and personal circumstances.
No. You can run a self-employed business as a sole proprietor without incorporating. Many Canadians operate successfully this way, especially in the early stages. Incorporation is optional but becomes beneficial as income grows.
Your personal RRSP stays yours. When you incorporate, you can set up a corporate RRSP or a spousal RRSP through the corporation, which may offer better tax planning opportunities. You should consult a tax professional about how to transition your savings effectively.
Yes, you can incorporate at any time during the year. However, you'll need to split your tax year between sole proprietor income and corporate income on your tax return. This creates more complexity, so most people choose to incorporate at the start of a new tax year.
Not necessarily. While your corporation pays corporate tax, you can control when and how much you withdraw as income, potentially deferring personal taxes. The overall tax picture depends on your withdrawal strategy and local tax rates. Use a tax calculator to compare both scenarios for your income level.
