How does the Interest income get taxed inside a corporation?

Having a GIC or interest genreating income inside a  corporation is always a great idea. The simple reason is taxation.

Before we jump into taxation of interest income inside a corporation, one should also be aware of how RTDOH works. RTDOH is refundable dividend tax on hand. The tax rate paid by the corporations on investment income is significantly higher than rate paid on business income, and generally higher than top marginal rate for individuals. In Alberta, the tax rate for investment income is 46.67%, where RTDOH credit of 30.67% is available and may be refunded to the corporation on the basis of $1 for every $2.61 of taxable dividend paid.

Interest income earned in the corporation: $1,000

Corporate Tax 46.67%: $467

RDTOH : $307    

Available for Dividend: $840

Tax Payable by corporation: $160

Tax payable by an Individual on dividends: $355

Total Individual and corporate tax: $160+$355 = $515

Tax at top marginal rate if the interest is received by that individual directly will be $480.

Here, we can see that a corporation will pay higher taxes as compared to individuals on the investment income. No doubt, its a very safe investment, however, it should match your investment objectives.
