(2021) What is the advance flat rate?

The so-called advance lump sum ensures that a certain minimum taxation takes place at the investor level - even in cases where a fund makes no or insufficient distributions. The amount of the advance lump sum always refers to the previous year. When the shares are actually sold, the advance lump sums taxed up to that point are deducted from the sales proceeds (sales proceeds minus acquisition data minus advance lump sum).

This means that a capital gain is reduced (and thus also the tax burden). In the case of a capital loss, the advance lump sum already calculated increases your capital loss. Double taxation is therefore excluded.

The advance lump sum was first introduced and taxed at the beginning of 2019 - for the 2018 tax year it is not yet relevant for tax purposes.
