The Small Business Deduction (SBD) can significantly reduce the federal corporate tax rate on eligible income: but the rules matter.
For a Canadian-controlled private corporation (CCPC), the SBD generally applies to the first $500,000 of active business income. However:
• Associated corporations must share the $500,000 business limit.
• Significant passive investment income can reduce access to the SBD. The business limit may begin decreasing when adjusted aggregate investment income exceeds $50,000 and can be eliminated at $150,000.
• Federal and provincial rules may differ, so proper planning is essential.
Action steps for your business:
1. Confirm your corporation’s CCPC status and identify active business income.
2. Review associated corporations and complete required CRA allocations and filings on time.
3. Monitor passive investment income throughout the year.
4. Track income carefully by source to support a clean, accurate year-end.
Don’t wait until year-end to discover that your SBD access has been reduced. A timely review can help you plan with confidence.
