Tax return almost identical to the tax-saving statement (of Academic Consortium), an enormous price advantage!

I have this software installed and used yesterday and found that the surface is almost identical to the tax-saving Declaration 2014 (Academic Consortium). Given the price difference (4.99 vs. 26.99), the question arises, where the stems? I suspect a sublicense to another publisher (in this case, of the Academic Association of the Wolters Kluwer Germany GmbH). And what is in the license terms?

"Licensing terms of Wolters Kluwer Germany GmbH (" Wolters Kluwer ') for brand products Akademische Arbeitsgemeinschaft "

To illustrate the similarity I add two clients images with screenshots of the two programs, a (tax-savers in 2014 vs. tax-saving declaration in 2013 because I have only the last year's version).

So who wants to save money, reach for.

Supplement for further use: There are some differences, namely that, for example, the component for creating a revenue-surplus account (yours) by lack of self.. That's an important shortcoming, which is why I want to pull a star. For employees, however, that should not carry weight because the main use seems to be the same as using tax-saving statement (not self-employed income, advertising costs, etc.).

Addendum 2: The data acquisition of the control-saving explanation for tax-savers did not work with me. Although the program can not accept files with the extension ".ESt2012" loud dialogue, came when entering my last year file a message indicating that the data can not be taken for a different version of the program. However, it went quite quickly, as I have just opened two programs in parallel and acquired the data on copy-paste.
