❓ Frequently Asked Questions: Canadian Corporate Income Tax
What qualifications make a company a CCPC in Canada? ▼
To be a Canadian-Controlled Private Corporation (CCPC), the corporation must be incorporated in Canada, resident in Canada throughout the tax year, and not controlled directly or indirectly by non-residents or public corporations traded on designated stock exchanges.
How does corporate income split when profits exceed $500,000? ▼
If an eligible CCPC earns $800,000 in active taxable profit, the first $500,000 is taxed at the low small business rate (9% federal + provincial small rate, e.g. 12.2% in Ontario). The remaining $300,000 above the business limit is taxed at the general corporate rate (15% federal + provincial general rate, e.g. 26.5% in Ontario).
What is the passive investment income grind rule? ▼
Under federal tax rules, every dollar of Adjusted Aggregate Investment Income (AAII) earned in a corporation exceeding $50,000 reduces the corporation's active small business deduction limit by $5. Once passive income reaches $150,000 in a tax year, the small business deduction limit is completely eliminated ($0), taxing all operating profits at general corporate rates.
How does salary vs. dividend remuneration compare for owner-managers? ▼
Paying a salary creates an expense deduction for the corporation, generates RRSP contribution room, and requires CPP contributions. Paying dividends is not deductible by the corporation (paid from after-tax profit), avoids CPP payroll deductions, and takes advantage of dividend tax credits on the shareholder's personal tax return.
What are corporate tax installment payments? ▼
If a corporation's total tax payable exceeds $3,000 in both the current and preceding tax year, the corporation is legally required to remit monthly (or quarterly for eligible small CCPCs) tax installments throughout the fiscal year to avoid CRA installment interest penalties.
