Investment income inside a Canadian corporation
Distinguish retained profits, investment income and the tax consequences of distributions.

Separate the balance from the income
Retained earnings describe accumulated profits retained in a corporation; they are not necessarily cash sitting in a bank account. Investment income is income generated by assets. A rule based on investment income is not a rule triggered simply because the corporation retains the same dollar amount of business profit.
Avoid one-rate comparisons
Different income types can receive different tax treatment. The corporate tax system also includes refundable-tax mechanisms. A headline rate applied to one kind of income is not a complete measure of the final corporate and shareholder tax cost. Ask for a comparison that includes distributions and any relevant refunds.
Review the small business deduction
Adjusted aggregate investment income can affect a CCPC’s federal small-business limit, with associated corporations included in the calculation. The commonly discussed range is $50,000 to $150,000 of that income. The full calculation and provincial treatment need review; a fixed dollar tax penalty does not apply to every owner.
Give each portion of the surplus a job
Set aside working capital and planned purchases before assessing long-term alternatives. Ask the accountant to identify the relevant income types and the effect of any proposed change. An investment decision should reflect access needs and risk as well as tax.
Questions to bring to your specialist
- What part of the balance is actually available cash?
- Which income types and refundable taxes apply?
- How do associated companies affect the calculation?
