How a 1e plan works
The name comes from Article 1e of the Ordinance on Occupational Retirement, Survivors’ and Disability Pension Plans (BVV 2). It allows pension institutions that insure exclusively salary components above one and a half times the upper limit amount to offer their insured members a choice of several investment strategies. In 2026 that threshold is CHF 136’080. Everything below it stays in the regular pension fund, the so-called base plan.
For this, your employer signs a contract with a 1e collective foundation and defines the pension plan: savings contributions of up to 25 % of the insured salary, risk benefits in the event of death and disability, and the selection of strategies. The foundation may offer at most ten strategies per plan, and at least one of them must be low-risk, for example an account solution without securities. You choose from this selection and can switch later.
The decisive difference from the pension fund: there is no minimum interest rate and no guarantee. Whatever your strategy earns is credited to your account, and so are losses. In return, there is no redistribution from working members to pensioners, and the foundation can never become underfunded. When you leave the company, you take the actual value of your assets with you, even if it is currently below the contributions paid in. That is why many foundations offer a vested benefits solution in which you can continue the same strategy.
For tax purposes, the same rules apply as for the pension fund: contributions and voluntary buy-ins reduce taxable income, the capital grows tax-free, and the payout at retirement is taxed separately at a reduced rate. Because the insured salary in a 1e plan is high, the buy-in potential is high too. According to PwC, the average buy-in in 2024 was CHF 22’200 per insured member.
