Many citizens now have the chance to voluntarily pay more into the pension fund.
On the one hand, this allows you to top up your later pension; on the other hand, it can help to close insurance gaps and secure a statutory old-age pension in the first place.
However, if you want to shoot more for 2020, you have to hurry. The Deutsche Rentenversicherung is still accepting applications until March 31st. The transfer itself can still be made afterwards. WELT gives an overview of who can voluntarily top up and how that works.
