The pillar 3a is a tax-privileged category of retirement savings. There are pillar 3a savings accounts, retirement funds, asset management services, and life insurance products. What makes these different from regular financial products is that your money is held in trust by a retirement foundation.
There is no specific obligation to make payments into the pillar 3a. If you use a pillar 3a savings account, retirement fund, or asset management service, you can simply stop making additional payments at any time you choose. Your existing pillar 3a assets will remain as they are, and continue to earn interest or returns.
If you use a pillar 3a life insurance product, things are more complicated, as the terms and conditions of your insurance policy add another layer of limitations. As a general rule, insurance companies give you the option of putting your insurance premiums on hold. In this case, the existing equity (cash value) that you have already accumulated in your policy will remain intact, but you will not build additional equity in your policy while your premiums are on hold. We at moneyland.ch generally recommend avoiding pillar 3a savings products based on insurance because these products are often complicated.
When you become unemployed, you can continue making payments into the pillar 3a as long as you are receiving benefits from Swiss social unemployment insurance, as the unemployment benefits are subject to OASI contributions. If you do not earn an income on which you have to pay OASI contributions (a salary or Swiss unemployment benefits, for example), then you cannot contribute to the pillar 3a until you begin receiving an eligible income again. Your existing pillar 3a benefits will remain intact. If you use a pillar 3a solution based on life insurance, the insurance company will generally put your insurance policy on hold, or give you the option of converting it into a pillar 3b policy (a normal life insurance policy outside of the pillar 3a).
