Take a deep breath, everyone! I'm not trying to accuse anyone of any criminal activity - I'm just stating that unless you have managed to claim back training costs, then Eu15oo is not the right amount of tax in six months and you need to go through the figures again to make sure you pay the correct amount. like I said, a typical amount is about 1/3 of your earnings.
It's amazing how defensive some people get, banding around accusations of libel when someone is just making a minor point.
