If you are self-employed and running a SaaS, the rate is actually 8.5% of revenue (PKWiU 58.29.40). Source: I am self-employed and running a SaaS. With my cost structure my (calculated for comparison) effective income tax rate is 13.5%, and that includes all social security and health insurance payments. It's unbelievably good, socially unjust, and I don't think it will last, but here we are. Poland also happens to be a really nice place to live, although if you don't speak Polish (or don't have a friend/spouse who does), dealing with government institutions can be a pain. Oh, we also have a terrible chaotic populist government and a bunch of other problems, but that seems to be the case everywhere these days, so.
