The annual tax return is - apart from possible refunds from - a mostly bureaucratic mandatory stroke. By tax2015 control program and its predecessors, I have been working for many years. Who led his tax return electronically, structured and wants to make, not least with data acquisitions from the previous year, can go wrong with tax2015 nothing! Good and current assistance / judgments / references for the necessary inputs, system tables, "accounting" of depreciation, good leadership by the tax return, preview / calculation and delivery / balancing of the decision by ELSTER interface. What more do you want? OK, maybe an accountant ;-)
