It is little said, the calculation of this tax is enormously important, especially since the non-payment leads to the fact that you will have quite large fines. Accountants, being people, can sometimes make mistakes in calculations. In order not to have such problems I use an online platform that carries out the entire accounting. So both salaries and fees I pay through ThePayStubs. By this method I also have transparency, but it is much simpler, because the bank alone makes payments and I do not forget about this.
