I can think of one: The CEO of a Dutch corporation (BV) needs to receive a minimum salary of €47.000 per year, even if your startup is operating at a loss. You can easily get this reduced by the tax inspector if you show a loss but it's a hassle and you can't reduce it to zero. (So you if you fund your own incorporated startup you will have to pay your saving to yourself, and lose taxes along the way)
Please explain what you mean by this for the Netherlands? (I say this as an expat Brit with his own business in the NL)
