There are two types of dividends with different gross-up and dividend tax credit amounts. An “eligible dividend” is generally a dividend paid out of the corporation’s business income that was subject to the general corporate rate of tax, which is between 25% and 30%, depending on the province. A “non-eligible dividend” is generally a dividend paid out of the corporation’s income that was subject to the small business deduction, so that the corporation’s tax rate on the income was about 9% to 13%, depending on the province.
For eligible dividends, the gross-up is 38% of the dividend and the federal dividend tax credit is 6/11ths of the gross-up. The provincial credit depends on the province. For non-eligible dividends, the gross-up is 15% of the dividend and the federal credit is 9/13ths of the gross-up. Again, the provincial credit depends on the province.
The gross-up of the dividend is meant to put the shareholder in roughly the same position as if the shareholder earned the corporation’s pre-tax income. The shareholder then computes their tax payable on that amount, and the dividend tax credit is meant to roughly offset the corporate tax payable. The net result, if there is perfect “integration”, is no double taxation, and the shareholder pays personal tax on the corporation’s underlying income at the shareholder’s marginal tax rate, while getting a refund of the tax the corporation paid.
