Overpaid social security contributions

I receive the adjustment every year. Then I either get the excess refunded, or I have to pay what I still owe. But what you mean, as exists with vAT administration, does not exist with social security contributions, in my opinion.

Hoi DC, thanks for the feedback. Does that adjustment happen automatic for you?

You're welcome ;)

I just receive an invoice from (if I have to pay) or a credit note (if I get a refund). Of course, i don't know if that's the case everywhere. Perhaps you should check with your social secretariat to find out how it works for you.
