Does the timing of when I incorporate affect my salary or dividend options in the first year?

Incorporating mid-year creates a transition from sole proprietorship income to corporate income. For the months you operated as a sole proprietor, income is reported directly on your personal T1. For the months after incorporation, income belongs to the corporation and personal tax only arises when you extract it through salary or dividends.

If you incorporate in October, for example, you have a two-month corporate year before December 31 if you choose a December year end, or a longer first fiscal period if you choose a later month end. The corporation's income in those two months is low, meaning the small business deduction may shelter it all at the low corporate rate. Salary drawn from the corporation in those months reduces corporate income and raises your personal income for the year — timing the salary draw affects which tax year it lands in and your effective bracket.

In the first year, the most common issue is ensuring the sole proprietorship income and corporate compensation are both properly reported, with no double-counting and no gap. The transition also requires a new GST/HST account for the corporation and, if assets were transferred, potentially a section 85 rollover election. Planning the incorporation timing and the first year's pay structure together with your accountant avoids costly corrections later.
