3rd pillar: self-provision
Pillar 3 in the Swiss pension system is the private, self-determined pension provision. Pillar 3 is divided into Pillar 3a, which is subsidised by the state by allowing you to deduct payments from your taxes, and Pillar 3b. Pillar 3b refers to normal saving. In contrast to pillar 3a, the money in pillar 3b is not tied up and can be withdrawn at any time.
