However, in two scenarios, Recipient will be required to pay a refundable tax on dividends it receives from Payer. The tax is 38.33% of the dividends received, and is refundable when Recipient in turn pays out dividends to its shareholders, as further explained below. The refundable tax is called Part IV tax because that is the Part of the Income Tax Act that imposes this tax.
First, if Recipient is a private corporation and it receives dividends on “portfolio shares”, the refundable tax will apply. By “portfolio shares”, we mean that Recipient owns 10% or less of the shares of Payer (counting either votes or fair market value). The 38.33% tax is added to a notional account of Recipient called refundable dividend tax on hand (“RDTOH”). The tax is refunded to Recipient when it pays dividends to its shareholders, on a basis of 38.33% of the dividends paid to its shareholders. The payment of those dividends then reduces the RDTOH.
