Incorporation is often pitched as an automatic tax win. In practice, it can lower your tax — or it can add cost and complexity that outweighs the benefit. The decision comes down to how much you earn, how much you need to live on, and how long you can leave money inside the company.
When incorporation starts to pay off
Incorporation typically makes sense once your net business income consistently exceeds your personal living costs. At that point, the surplus can be retained inside the corporation and taxed at the lower small business rate rather than your top personal rate. Below that threshold, the added compliance cost usually outweighs the saving.
The small business deduction
A Canadian-controlled private corporation pays a reduced tax rate on the first $500,000 of active business income. Money retained inside the company isn't taxed again until you pay it out — but it is not tax-free forever. The strategy is deferral, not elimination.
The catch
Incorporation brings an annual T2 return, a separate corporate bank account, and a more structured way of paying yourself through salary or dividends. Model the after-tax outcome with a professional before you incorporate — not after — so the structure matches your actual numbers.
