Hi Sam,
The corporate tax rate for a non-CCPC is 27% on average (varies by province). Assuming a non-CCPC made a profit of $100,000, a corporate tax is payable for $27,000. In addition to this, a non-resident withholding tax of 25% is deducted from dividends paid to non-resident shareholders. Assuming a dividend payment of $73,000, the non-resident dividend withholding tax amounts to $18,250. Therefore, the total burden of tax is $45,250 or 45.25%.
The 25% non-resident tax deducted from dividends may be reduced under a tax treaty with Canada. For example, the Canada-US treaty stipulates that the non-resident tax is 15% where the shareholder is a US individual and 5% where the shareholder is a US corporation.
Tax relief, such as foreign tax credits or tax deductions, may be available in the foreign country. This will help reduce/prevent double taxation.
