Taxes may apply when dividends are distributed. You bear responsibility for this as a shareholder. The withholding tax, the solidarity surcharge and any church tax are deducted from the gross dividend. In the case of dividends on foreign stocks, so-called withholding tax may also be levied. The net dividend will then be paid out.
You will also receive your annual tax certificate in the first quarter of the following year, which will show you the tax you have paid.
If the dividend is reinvested, no taxes will initially be due.
