Passive income, interest, taxable capital gains and certain rents as examples, earned by a CCPC is subject to a high corporate income tax rate of approximately 50%, a portion of which is accumulated in a notional account called the Refundable Dividend Tax On Hand (“RDTOH”). The RDTOH account is a mechanism that is used to simulate for the corporation the highest individual tax rate. In effect, the company “pre-pays” taxes to the federal government and is credited an amount in this pool. The CCPC is therefore entitled to a refund of its RDTOH of $38.33 for every $100 of dividend it pays to its shareholder, regardless of whether the dividend is sourced from the income it has generated from its active business or from its passive income. The refund is triggered at the time the dividend is paid since at this point the shareholder herself will now pay income taxes on that dividend earned. The RDTOH account is therefore used to achieve the integration at the corporate level by taxing passive investment income at roughly the top personal tax rate while it’s retained within the corporation.
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
