I since the time of use after my training every year WiSo control software. For years, under Windows, as I already had a Mac. Since 2 years now I use WiSo for Mac. The price has slowly adapted to luck at the Windows price. I am in this respect a "Schäppchenjägerin". At the new look and feel on Mac I got used quickly. The import of the control file from the previous year (under Windows created) was not a problem. The file extension is the same in both operating systems. This year I have the first time the "call of the tax assessment notice by ELSTER" used. I was the possibility the decision with the data collected in the program to submit excited. The explanation for the last year has also been issued and I hope the demand under the current version runs just as smoothly as in the previous year. The menu navigation and memo functions are what appeals to me personally the most. It should be simple and plausible even for lay people like me who are not a tax advisor. In the early years I have allowed myself to accompany always with the interview. Meanwhile, I no longer need this function. The program provides tips and suggestions for improvement. It checks calculated etc. In about 95% of the taxes previously submitted by me the result was right in line in the decision of the tax office with the calculation of the program. And there were many years of program experience! All these are for me good conditions to continue this program to remain faithful. Regular updates to the control content delivered to the installation.
