OASI: the cornerstone of the Swiss pension system

OASI is part of the first of three pillars on which the Swiss pension system is based. The three-pillar system comprises the state pension, occupational pension provision and private retirement savings.

Pillar 1 is mandatory for everyone. Pillar 2is mandatory for employees from 1 January after their 24th birthday and if they earn more than CHF 22,680 per year (figure for 2025). The aim is for retirees to receive a combined OASI and occupational pension that allows them to maintain their accustomed standard of living when they retire. As a rule of thumb, the target is 60% of the final salary. Pillar 3is voluntary. You can use it to reduce any pension gapsand maintain your standard of living when you retire.

What does pillar 1 cover?

“OASI” stands for old-age and survivors’ insurance, which forms the largest part of the first pillar. It is supplemented by disability insurance and any supplementary benefits. Together, they comprise the mandatory state pension provision. The aim is to ensure people can maintain a basic standard of living when they retire or become disabled and protect their dependents if they die.

Old-age and survivors’ insurance (OASI)

OASI provides retirement provision and offers protection for surviving dependents. Since 1948, the benefits provided under OASI have been adjusted more than 10 times – often they were increased though sometimes reforms were introduced.

Disability insurance

Disability insurance primarily helps with integration measures, but also with financial benefits such as daily allowance payments and disability pensions. Disability insurance comes into play when someone’s ability to work is permanently impaired for health reasons. It doesn’t matter whether the impairment is physical, mental or psychological.

Supplementary benefits

In some cases the OASI or disability pension benefits may be too low to cover the cost of living. In 2023, this applied to 50% of all disability pension recipients. In addition, those with low assets (below CHF 100,000 for single persons) and no other sources of income can apply to the supplementary benefits office to top up their OASI or disability pension and ensure a minimum standard of living.

Compensation for loss of earnings

The loss of earnings compensation scheme provides compensation for loss of earnings during maternity leave and – since 2021 – for paternity leave. Traditionally it replaces part of the lost earnings for all those carrying out military service or civil protection duties.

OASI contributions

Persons who live or work in Switzerland are subject to mandatory OASI contributions. The obligation to pay contributions ends in principle when a person reaches the reference age or – if they continue to work beyond that – when they are no longer employed. However, those who stop working before the reference age pay OASI contributions like all other non-employed persons, even if they draw an OASI pension early. In the case of married couples, a spouse who is not employed is co-insured if their spouse is employed and pays at least twice the minimum contribution (2025: CHF 1,060).

What contribution levels apply to OASI, disability insurance and compensation for loss of earnings in 2025?

Employees

10.6% of the gross salary; half is paid by the employer

Non-employed persons

Minimum of CHF 530, maximum of CHF 26,500, dependent on retirement income and assets

Self-employed persons

10.0% of the annual income; reduced contribution rates apply for incomes below CHF 60,500

OASI pension

The pension amount you receive depends on your income and whether you have the full amount of contribution years. In 2025, men who have paid contributions for 44 years (this applies to women as of 2028) will receive a minimum pension of CHF 1,260 per month and a maximum pensionof CHF 2,520.

If your individual OASI account has any contribution gaps, your pension will be lower. When gaps arise, they often go unnoticed, for example due to stays abroad. They can be closed retroactively for up to five years – or by working beyond the reference age and having the contributions credited before you reach the maximum age.

Impact of taking early retirement or deferring retirement

You can retire between the ages of 63 and 70. Early retirement is between ages 63 and 65, while if you retire after the age of 65 it is considered deferred retirement.

The challenges facing OASI

Demographic change – i.e. fewer contributors and more pension recipients – makes it difficult to finance the first pillar, as it is funded by a pay-as-you-go system.

The “OASI 21” reform aims to stabilize the social insurance system by 2030. The new rules for OASI came into effect on 1 January 2024. The statutory retirement age – now called the “reference age” – for women will be gradually aligned with that of men (65 years). Rules on compensation payments apply for women in the transitional generation, i.e. those born between 1961 and 1969.

In addition, you now have more flexibility when it comes to drawing a pension than before: between the ages of 63 and 70, you are relatively free to choose when you want to start receiving your pension – or a partial pension. If you continue to work beyond the reference age, you now have the chance to reduce gaps owing to missing contribution years.

Conclusion

OASI forms the basis of the Swiss social security system. It provides assistance in many situations in life. Just because contributions are automatically deducted by the employer does not mean that receiving benefits will be quite as easy. You need to take action to make use of and maximize the available options for drawing a pension. Submitting claims and applications, meeting deadlines, closing gaps – all of these require action on your part. Take some time to handle these tasks every four years. Check your individual account statement, which you can order from your compensation office.
