How should I think about salary versus dividends for my retirement as an Ontario business owner?

Retirement planning for an incorporated Ontario business owner involves three main vehicles: the corporate retained earnings pool, personal RRSP savings, and CPP entitlement. The salary-dividend mix directly determines how much flows into each bucket.

Salary generates RRSP room (18% of prior year earned income, to the annual maximum) and CPP contributions. Over a career, maximizing RRSP contributions through salary provides a tax-sheltered investment pool that grows outside the corporation and avoids the passive income rules that can erode the corporate small business deduction. CPP, while modest relative to high business incomes, provides a government-backed indexed income stream starting as early as age 60.

Dividends, on the other hand, allow more retained earnings to grow inside the corporation where investment returns compound at the corporate tax rate on passive income. At retirement, drawing down the corporate account through a combination of dividends and potential IPP, retirement compensation arrangements, or other mechanisms gives you flexibility. Many business owners use a hybrid strategy: pay enough salary to max the RRSP, then draw dividends. The right balance shifts at different life stages and income levels. A financial planner and tax accountant working together are the right team for this decision.
