I can only agree with the previous speakers. Despite various updates no data from previous programs (2011, 2010.2009, ....) taken. In addition, the tax law does not seem to be up to date. I have around 250 euros to get less from Finazamt than me the program has calculated. This is really bad. For the next tax return I will probably no longer rely on WISO. Too bad, because I have my friends from before the program even raved over the years .... The two stars does the process because it is stable and the entry is easy.
