It's funny how the author complains that he has to pay 15% taxes in Romania. In Germany you have to pay ~50% for taxes and different duties and all expenses are much higher than in Romania. Also German tax authorities are known for "torturing" self-employed people with different types of requests. So when I worked as freelancer in Germany I voluntarily abstained from possible tax reductions via expenses, because German tax authorities will make your life a hell to force you pay as much taxes as possible.
