Understanding Corporate Tax Rates in British Columbia

The Canadian Corporate Tax Landscape

For business owners operating through a corporation in British Columbia, understanding the tax landscape is crucial for effective planning and forecasting. Corporate tax rates in Canada are comprised of a federal component and a provincial component.

The Small Business Deduction (SBD)

Canadian-controlled private corporations (CCPCs) benefit significantly from the Small Business Deduction. This reduces the corporate tax rate on the first $500,000 of active business income. In BC, the combined federal and provincial corporate tax rate on income eligible for the SBD is highly competitive, allowing businesses to retain more capital for reinvestment.

General Corporate Tax Rates

For active business income that exceeds the $500,000 threshold, or for income earned by non-CCPCs, the general corporate tax rate applies. While higher than the small business rate, careful tax planning can still optimize your overall tax burden.

Passive Investment Income

It's important to note that the rules surrounding passive investment income earned inside a corporation have changed in recent years. Earning too much passive income can grind down your access to the Small Business Deduction on your active income. This makes proactive tax planning with professionals like the team at Ampowro essential.
