The tied pension plan (pillar 3a) is part of the private pension plan in the Swiss three-pillar system. Its aim is to secure the accustomed standard of living in old age. Since benefits from AHV and occupational pension plans cover only 60% of the last salary (often significantly less for higher incomes), pension gaps can be reduced through tied pension plans. Payments into pillar 3a are tax deductible. For insured persons with a pension fund, the maximum amount is currently CHF 7’056 (as of 2023).
