Dividend imputation is a corporate tax system in which some or all of the tax paid by a company may be attributed, or imputed, to the shareholders by way of a tax credit to reduce the income tax payable on a distribution. In comparison to the classical system, it reduces or eliminates the tax disadvantages of distributing dividends to shareholders by only requiring them to pay the difference between the corporate rate and their marginal tax rate. The imputation system effectively taxes distributed company profit at the shareholders' average tax rates.
