Ok so your an expat? Ok so let me tell you one thing the Belastingdienst don't play around I can tell you that .
As you don't have free cash flow as you state you need to be thinking about cheap relocation. Not sure what visa your gonna try to obtain to move to Singapore unless your Swiss? Would be interested to know how you plan on getting residency there which is not easy. But perhaps remote working visa could work for some other countries below:

Yes I am an expat and I don't want to mess up with NL Tax office I heard stories so that is why I don't want to cheat...
Malaysia could be done by MM2H (but that is on hold at the minute), Singapore is more tricky I agree but I am in conversation with my employer to maybe relocate me there.... TBC Dubai is just 'easier' but happy to hear other opinions
Thanks for the link will read the content later.
