You can of course but there are rules that you need to follow for the tax office; if they mark you as defacto employee in NL for a US company, different taxation applies. You are marked as not an entrepreneur or company in that case and you will be taxed (a lot) more. I didn’t say anywhere it is illegal or prohibited anyway (I just said you will be flagged as defacto employee which brings consequences); it is just not very smart as you will have all the bad things and none/little of the good things working like that.
