Dividends
Received from resident companies. In general, one-half of dividends received by resident companies from other resident companies may be excluded from taxable income. However, the full amount of the dividends may be excluded if either of the following applies:
-The recipient is a company listed on the Stock Exchange of Thailand.
-The recipient owns at least a 25% equity interest in the distributing company, provided that the distributing company does not own a direct or indirect equity interest in the recipient company
-Received from foreign companies. A Thai company that owns an equity interest of at least 25% in a foreign company can exclude dividends received from such foreign company from its taxable profit if, on the date of receipt of the dividend, it has held the investment for at least six months and if the profit out of which the dividends are distributed is subject to income tax in the hands of the foreign company at a rate of at least 15%
