From 2026 onwards, it will be possible to make retroactive payments for unpaid contributions to pillar 3a and deduct these from your taxes. Below is an overview.

Pension System in Switzerland

Switzerland’s pension system is based on three pillars: state, occupational, and private provision. The goal of this system is to ensure financial security and maintain the standard of living during retirement. Below is an overview of the three pillars:

 

1st Pillar

The state pension forms the first pillar of the Swiss pension system. Its purpose is to guarantee financial subsistence. It is financed on a pay-as-you-go basis, meaning that contributions are not saved individually but are used immediately to finance current pension payments.

2nd Pillar

The occupational pension forms the second pillar. It consists of the pension fund and accident insurance. Its purpose is to maintain the accustomed standard of living. It is financed through the capital funding method, meaning contributions are saved and later paid out as a pension or capital.

3rd Pillar

The voluntary private pension forms the third pillar. It complements the state and occupational pensions with the goal of closing potential pension gaps and securing the individual’s desired standard of living. On average, the 1st and 2nd pillars cover only about 60% of a person’s pre-retirement income. The remaining 40% can be covered through the 3rd pillar.

Example

Before retirement: Michael is approaching retirement and earns a net monthly salary of CHF 8,000. He has contributed to the mandatory pension system (1st and 2nd pillars) but does not have a 3rd pillar.

After retirement: The benefits from the 1st and 2nd pillars (AHV + BVG) cover approximately 60% of his pre-retirement income: CHF 8,000 × 60% = CHF 4,800.

Pension gap: Without a 3rd pillar, a shortfall of CHF 3,200 arises. With a 3rd pillar, Michael could build additional savings to maintain his lifestyle and close this gap.

What is the 3rd Pillar?

The voluntary private pension allows individuals to save additionally for old age. This helps close potential pension gaps and build further assets. The 3rd pillar is divided into two types of accounts – 3a (restricted pension provision) and 3b (flexible pension provision).

Pillar 3a

Pillar 3a is a restricted pension plan that primarily serves as financial security for old age. It is tax-advantaged by the government.

Tax Treatment

The annual amount contributed can be deducted from taxable income. Furthermore, the assets in a 3a account are exempt from wealth tax during the saving period. Upon withdrawal, the balance is taxed separately from regular income at a reduced tax rate.

Maximum Contribution 2025

  • Employees with an occupational pension: CHF 7,258
  • Self-employed persons without an occupational pension: CHF 36,288 (maximum 20% of net income)

Advantages

  • Tax savings
  • Closing pension gaps
  • Compound interest effect
  • Early withdrawals possible (e.g., for owner-occupied property)

Disadvantages

  • Funds are tied up
  • Annual maximum limit
  • Only available to individuals with AHV-liable earned income

Pillar 3b

Pillar 3b refers to free pension savings and offers more flexibility than the restricted Pillar 3a. Unlike Pillar 3a, there are no maximum contribution limits, and the amounts paid in are usually not tax-deductible.

Advantages

  • Flexible duration
  • Tax-free payout
  • No contribution limits

Disadvantages

  • No tax advantages (deduction only within the capped insurance allowance)
  • No statutory protection provisions
  • In some cases, limited product transparency

Can You Make Retroactive Contributions to Pillar 3a?

Previously, individuals who did not pay in the maximum amount in a given year could not make retroactive contributions. A parliamentary motion by Ettlin (June 19, 2019) instructed the Federal Council to create a legal basis to make this possible in the future.

Federal Council Decision of 6 November 2024

The Federal Council approved amendments to the Ordinance on Tax-Deductible Contributions to Recognized Pension Schemes (BVV 3). These came into effect on 1 January 2025.

New Regulations

Starting in 2026, in addition to the regular annual contribution, it will be possible to make an additional contribution (a so-called “small contribution”) to fill previous gaps. This allows retroactive payments and tax advantages to be utilized. However, gaps from years prior to 2025 can no longer be filled. To ensure compliance, the legislator introduced several conditions.

Conditions

  • The maximum contribution for the current year must already have been made.
  • Retroactive contributions are limited to the past 10 years.
  • The person must have earned AHV-liable income both in the year of the contribution and in the corresponding retroactive year.
  • Only one retroactive payment may be made per calendar year.
  • If a withdrawal was made within five years before the ordinary retirement age, no further retroactive contributions are allowed.
  • Early withdrawals for home ownership or self-employment are excluded from retroactive payments.
  • The retroactive contribution must be applied for in writing with the pension institution.

Advantages

  • Tax savings
  • Strengthening individual retirement savings

Weaknesses

  • Only possible retroactively from 2025 onwards
  • Administrative effort

Conclusion

The tax benefits of Pillar 3a make it an attractive tool to both save for retirement and reduce annual tax liabilities. Thanks to tax-deductible contributions, tax-free interest earnings during the accumulation phase, and preferential taxation upon withdrawal, significant financial savings can be achieved.

The new option starting in 2026 to make retroactive contributions provides additional flexibility and expands the financial planning options for employed individuals. It is worthwhile to make use of this opportunity to close pension gaps and benefit from tax advantages at the same time.

Do not forget: The final payment must be received by the pension foundation by 31 December.
