In the UK, we just got increased child benefit (new baby) and so our reduced council tax (local taxation based on [an imaginary] property value) has been increased. Net loss to us. Sadly we're not allowed to refuse the added child benefit.

Mind you the system is so complex that they couldn't tell us in advance what child benefit we'd get - presumably they just wait and see what number the computer spits out. This number appears to have a random perturbation.
