I don't think this means anything, there are indeed many other benefits, including direct payments. This is small and probably some legacy, but still not a reason to stop counting money. Well, 50 Eur is not 0 Eur. There are plenty of small credits for taxes and they keep adding up, fortunately, all is well automated and done without lifting your bottom from PC effortlessly (I've filled US tax papers for 7 years and even went to IRS to complain, thank you very much). Typically people end up with 800 Eur or so without even doing anything special.

That said, Vero just forgave me a few cents yesterday, they seem to drop taxes on certain transactions if they end up below 10 Eur or so - not worth the hassle, I guess, even electronically.
