Everything written in this article is true, but there are as usual more nuances to all of these. One of the primary reasons for me to go with a GmbH (and a holding) was the expectation of excess profits that I'd want to reinvest instead of drawing a salary. The other neat aspect of stacking a holding company on top of the operating company is that capital gains are not taxed in the event of a sale. That goes for investing into ETFs for example, but more importantly if the holding company ever sells the operating company then that sale is tax-free for the holding company. The ultimate owner is then able to pay out the proceeds and only be taxed using his personal capital gains tax rate (25%-ish).
