Combined federal + provincial rates on active business income, 2026 planning figures — including the mid-2026 small-rate cuts in Ontario, Quebec and Newfoundland. Passive income over $50,000 grinds the $500,000 small-business limit away ($5 per $1). Associated corporations share one limit; investment income itself is taxed separately at refundable rates. An estimate, not a filing.
