Last year, my refund to the penny exactly coincided with what WISO has calculated. If the tax return is coherent, the tax office to complain less. In my opinion, you really can not do any more rounded tax return as a layman.
I have let down my program right on the publication and it is not a lot time with me crashed. It runs like the famous sewing machine.

So a little addendum to my review. Yesterday was finally the tax bill in the mail and the tax office has everything I have mentioned in the program, without a murmur and waved through inquiries. Get the tax office even 30 euros more again than it has calculated my WISO Steuer. So I have the cost of the program loose inside :)
