In 2012 I had W iso, which I found a bit confusing. This is better for TAX, although I think that you could make it perhaps easier, but I do not want to evaluate here because I see it compared to W iso. It is worthwhile in any case to use such a program, since it contains a lot of tips and also lists paragraphs. So you do not forget anything and bring the maximum out. I also have a small business that I could thus work through everything. After submission to the FA came a positive review from, so everything is OK :)
