The Swiss pillar 3a is a tax-privileged category of private retirement savings and providence. Participation in the pillar 3a is voluntary and extends the coverage of the pillar 1 (government pensions, social security) and the pillar 2 (occupational pensions, occupational accident insurance). Contributions to pillar 3a retirement savings and premiums for pillar 3a insurances can be deducted from personal taxable income. Pillar 3a retirement savings do not count as taxable wealth.
Pillar 3a retirement savings are held in trust by a retirement foundation until you become eligible to withdraw them. You can transfer your pillar 3a assets from one foundation or solution to another, but you cannot withdraw them.
You become eligible to withdraw pillar 3a retirement savings 5 years before you reach standard retirement age (64 for women, 65 for men). You can also withdraw pillar 3a savings ahead of retirement age if you use the money to buy a primary residence, if you leave Switzerland permanently and under other exceptional circumstances.
When you withdraw pillar 3a assets, you pay a one-time capital withdrawal tax. In most cases this tax works out to be less than the cumulative income tax and/or wealth tax which you save by contributing to the pillar 3a.
Pillar 3a retirement savings can be placed in pillar 3a savings accounts or invested in pillar 3a retirement funds or pillar 3a asset management services. You can also use pillar 3a cash value life insurance to save for retirement, but doing this rarely makes financial sense.
