In this case, there are also rules for the amount of income you're allowed to get without a VAT.

I'm pretty sure in most EU countries the profitability of a service supported by patreon (that is, a passive income in sub 10k range) would be almost nullified if correctly accounted for taxation.

I had long discussions with friends about legally accepting money for side projects. It's a very hard topic to discuss.

I'd be curious to know if anybody in an EU country is able to legally accept and declare a side income and retain anything more than 30%.
