Whenever you are about to receive an announced dividend payment, you should check what withholding taxes or other charges may apply for the company's foreign shareholders.
You are living outside Germany and you hold 1 share with Allianz (ALV) a day before the ex-dividend date. Allianz announces a dividend payment of 9.60 EUR for its shareholders. Knowing that Germany applies a withholding tax on dividends paid to investors of German securities at a current rate of 25% with an additional “solidarity surcharge” of 5.5% of the 25% withheld, we can calculate the full net amount of the received dividend.
25% of 9.60 = 2.40 ->
-> 5.5 % of 2.40 = 0.132
9.60 - 2.40 = 7.20 - 0.13 = 7.07 EUR
In this case for a full amount of 9.60 EUR dividend payment, after withholding tax and the solidarity surcharge, the dividend you will receive is 7.07 EUR.
