How much is the dividend income tax?

In Korea, dividend income tax is 15.4% (14% income tax + 1.4% local income tax), which is automatically withheld at source before the dividend is deposited. For US stocks, 15% is withheld locally with no additional domestic tax.

What is the ex-dividend date?

The ex-dividend date is the day on which the right to receive a declared dividend expires. To receive the dividend, you must purchase the stock at least one business day before the ex-dividend date. After the ex-dividend date, the stock price typically drops by the dividend amount.
