How does the deduction of withholding tax work?

The capital gains tax is automatically withheld by the partner bank as soon as taxable investment income arises. This happens, for example, when a dividend is credited or you sell fund units at a profit. The bank then anonymously pays 25% capital gains tax plus solidarity surcharge (and if applicable, church tax) to the tax office.

Your earnings will therefore be paid out to you as net amounts.
