I've been using the control program for years now. In my view, the program has steadily worse, more complicated - but the 2006 tax return was definitely the last one that I have created with that software. Complicated menu navigation, an in my view illogical structure, and to top it all: With the dispatch of the tax return via Elster, an error message appeared. Three times I have written to the support, described the error message. Not once had it necessary to answer me. That's right traurig.Ich have then the tax return by mail passed-and I thought my part.
