Podsumowanie

For most freelancers and IT service providers the 12% lump sum is the most advantageous. With high costs (>40% of revenue) it is worth considering the progressive scale or flat tax. With income above 120,000 PLN per year the 19% flat tax is almost always better than the progressive scale.
