I recommend it because software: Quick installation u.fehlerfreier operation. Content very well because: precise, clear and, if necessary provided with explanations. The software has steadily improved over the last years. I prefer it over the WISO program because it is not so very inflated with multimedia animation. In the current test, the program has some also outperformed as the WISO software. The calculations by the way voted largely in line with the tax office numbers. Overall grade for use: 1.3. Please rate me!
