Incorporation

Incorporating does not reduce tax on money you spend — it defers tax on money you leave inside the company. This compares both structures at your profit level, including the salary-dividend mix and the annual cost of keeping a corporation alive.

  • Corporate vs personal
  • Salary / dividend split
  • Break-even income

Salary or dividend

Salary creates RRSP room$10,260 of new room at your current mix18% of salary
Salary builds CPPAn 11.9% cost, and a lifetime indexed pension in returnBoth halves
Dividends skip payroll taxCheaper now, but no RRSP room and no CPP creditNo CPP, no EI
IntegrationCanadian rules aim to make both routes cost the same; the differences are RRSP room, CPP and timingRoughly neutral
Passive investment income erodes the small-business rateOnce a corporation earns more than $50,000 of passive investment income in a year, the small-business limit is reduced $5 for every $1 above that, disappearing entirely at $150,000. A large retained balance invested in the company eventually undoes the advantage this page is showing.
Non-tax reasons often decide itLimited liability, selling shares with the lifetime capital gains exemption, and clients who will only contract with a corporation are frequently worth more than the deferral. So is the opposite: a corporation you cannot afford to administer properly is a liability.
How this is calculated

Corporate tax combines the federal small-business rate of 9.0% with your province’s rate of 3.2% on the first $500,000 of active business income, and the general rates of 15.0% and 11.5% above it.

Dividends are treated as non-eligible: grossed up 15.0%, then reduced by the federal credit of 9.0% of the grossed-up amount and an approximate provincial credit. Provincial dividend credits change frequently and are modelled as a single rate, so treat the dividend figures as close rather than exact.

The deferral estimate applies the gap between your personal marginal rate and the small-business rate to the balance left inside the company. It is a deferral, not a saving: withdrawing that money later triggers dividend tax.

Salary is assumed to carry self-employed CPP, because a sole shareholder pays both the employee and employer halves. EI is not payable on a controlling shareholder’s salary.
