And again it goes to the troublesome issue tax return. And like the last years I'm doing my tax return with this program, in which the data acquisition from last year a lot of work will be spared. Because changes to year at us much of the year, I have to really adjust just a few numbers and get rid of it. For this I find the plausibility check very helpful here. So far I had not received any inquiries of the tax office, because I already could correct any errors before.
