Investing Through a Canadian Corporation: What Business Owners Should Understand About Passive Income
Your corporation is profitable.
Cash is building up.
You do not need all of it personally.
So naturally, you start thinking:
โShould I invest this money inside the corporation?โ
That can absolutely make sense.
But corporate investing is not as simple as opening an investment account and chasing the best return.
Once your corporation starts earning passive investment income, different tax rules come into play.

โข Interest income
โข Dividend income
โข Rental income
โข Capital gains
โข Foreign investment income
And each can create a different tax result.
For Canadian-controlled private corporations, passive investment income can also become important when looking at the Small Business Deduction.
Once adjusted aggregate investment income becomes high enough, the corporationโs small business limit can begin to shrink.
That means a growing investment portfolio can affect more than just the tax on the investment itself.

โข Is this truly excess cash?
โข How much passive income could the portfolio generate?
โข How will that income be taxed?
โข Could it affect the Small Business Deduction?
โข Does the corporation still need access to the money?
โข Is investing personally or corporately more efficient overall?

Corporate investing can be a powerful wealth-building tool.
But the strategy should be built before the investment portfolio gets large.
