The lump sum paid for complementary activities should be taken into account when calculating your pension. As far as I know, that is not the case and it is not fair that we pay extra into the pension fund and get nothing out of it. There is also nothing to gain from paying a lump sum for health insurance. Those of us who are employed and already pay all the benefits there are still paying EUR 760 a year for the lump sum. But is that fair and incentive-based? We do, of course, pay taxes for the activity. So if we are already paying twice, we should take that into account in our pensions.
