Switzerland's 3-pillar principle

The basis for material security in Switzerland is the 3-pillar principle. It is the pension system guaranteed by the Federal Constitution and has proven itself over several decades. The aim is to provide Swiss citizens with financial security in old age and in the event of disability. In addition, dependents should be covered in the event of death.

Demographic developments also pose major challenges for Switzerland. Nevertheless, spreading the responsibility over several pillars makes pension provision more stable. This makes it all the more important for each individual to know the instruments, the specialists involved, and their areas of expertise. This article is intended to serve this purpose and provide an overview of the individual possibilities.

The most important facts in brief

• Retirement provision rests on three pillars: the federal AHV and IV, occupational pension provision and private provision. This is set out in the constitution (BV Art. 111 para. 1).
• First pillar: the full AHV retirement pension runs from CHF 1,260 to CHF 2,520 a month. The maximum is exactly twice the minimum (AHVG Art. 34 para. 3 and 5, amounts in force since 1 January 2025).
• Second pillar: the insured portion of salary runs from CHF 26,460 to CHF 90,720, so at most CHF 64,260 (BVG Art. 8, amounts set by BVV 2 Art. 5, in force since 1 January 2025).
• Third pillar: anyone belonging to a pension fund may pay CHF 7,258 a year into Pillar 3a, otherwise 20 percent of earned income up to CHF 36,288 (BVV 3 Art. 7 para. 1).
• The constitution sets no percentage target. It requires the first two pillars together to let people maintain their accustomed standard of living (BV Art. 113 para. 2 let. a). The widely quoted figure of around 60 percent of the last salary is the BVG benefit objective.

The story: A social insurance system is created by referendum

The Health and Accident Insurance Act (KUVG) was passed in 1911 and approved by popular vote in 1912. Thirty-six years later, on 1 January 1948, the Old-Age and Survivors Insurance (OASI) was created. The two world wars were major triggers for this insurance. Many soldiers and their families were in dire straits because they were no longer able to work due to wounds. Families also experienced economic hardship due to the death of their main breadwinner.

It took many parliamentary initiatives before a nationwide solution was found. In 1960, the insurance was supplemented by disability insurance.

Many years later, the 3-pillar principle was enshrined in the Federal Constitution. On December 3, 1972, the Swiss approved the model with 73.95 percent of the popular vote and all 22 cantonal votes. For the first time in the history of Switzerland, a clear system was created that offered the population protection against the risks of disability, old age, and death of the main provider.

Before social insurance became part of public law in Art. 111 ff. of the Swiss Federal Constitution (BV), there were various institutions for this purpose. They were self-organized groups, as well as institutions to which those in distress could turn. These included, for example, welfare for the poor, mutual aid societies, and private insurance companies.

Structure and operation of the 3-pillar principle

The system is one of the fundamental values of Switzerland. It guarantees social security on a collective level and enables people to live a life of self-determination in old age. This objective is a major challenge in its implementation. After all, all pension systems are subject to demographic change and have to face a changing society.

In Switzerland, this means in particular:

• Anyone retiring today at 65 has a statistical 20.7 years ahead of them; for women it is 23.2 years. Twenty years ago the figures were 18.1 and 21.6 (BFS, 2025).
• Life expectancy at birth stands at 82.7 years for men and 86.3 for women (BFS, 2025). The rise continues, but according to the Federal Statistical Office it has slowed of late.

The 3-pillar principle does not remove the need for adjustment, it spreads it. Each pillar has its own purpose and scope of benefits: the first secures basic needs, the second is meant to allow people to maintain their accustomed standard of living, and the third supplements both on a voluntary basis. Solidarity and personal responsibility interlock within it.

The first pillar includes only mandatory benefits. Likewise, some of the second pillar insurances are standard. Another part of the second pillar is voluntary. The third pillar is based on completely voluntary benefits with its private insurances.

Pillar 1: Securing your livelihood, the state pension plan

The first pillar is based on the principle of solidarity. Employees (including cross-border commuters) and employers pay monthly contributions, which finance the payments to current pensioners. The reference age (formerly the ordinary retirement age) is 65 for men. For women it is being raised from 64 to 65 in stages under the AHV 21 reform since 2025, by three months per birth year (cohorts 1961 to 1963), so that 65 applies uniformly from the 1964 cohort onwards. The pension is granted upon application. If you want to know how much pension you can expect, you can apply to the cantonal compensation office for an advance calculation.

The maximum OASI pension is CHF 2,520 per month and the minimum CHF 1,260 (in force since 1 January 2025, unchanged in 2026). These pensions require the full contribution period.

With this pillar, Switzerland fulfills its duty as a welfare state. In old age and the event of disability, the beneficiary’s livelihood is secured. However, you cannot expect more from the first pillar.

Features 1st pillar

The main features of the first pillar are:

1. mandatory pension plan
2. performances:

• Old-age and survivors’ insurance (OASI)
• Disability insurance (DI)
• The supplementary benefits (EL) for OASI and DI
• Unemployment insurance (ALV)
• Maternity allowance (MSE)
• EO (according to the income replacement regulation, benefits during military service, civil defense, or civilian service)

3. Objective: Securing livelihood
4. Financing: pay-as-you-go system (paid in by employed persons to payout approved pensions)

Features of the OASI

The OASI is national insurance. It covers all persons who live or work in Switzerland. This means that the insurance also covers cross-border commuters, guest workers, and people who are not gainfully employed (students, invalids, pensioners, housewives).

The OASI contributions are paid by all insured persons. Only children are exempt from this. Married persons who do not receive any income from gainful employment are also required to pay contributions. However, a limit applies to this contribution, which corresponds to twice the minimum contribution of the gainfully employed spouse.

Employee contributions are paid by the employer. The amount is based on income following the assessment for direct federal tax. Self-employed persons settle directly with the compensation office.

Pillar 2: Occupational pension provision, a building block for securing the standard of living

All employees are insured against disability from the age of 17. In addition, the family is financially protected in the event of death. The benefits are extended from the 24th birthday to include retirement benefits upon retirement.

The BVG itself names no percentage. It requires occupational provision, together with OASI and DI, to let people continue their accustomed standard of living in an appropriate manner (BVG Art. 1 para. 1). The widely quoted figure of around 60 percent of the last salary is the BVG benefit objective. What a given case actually produces depends on the contribution period, the salary level and the pension fund’s own regulations.

Features 2nd pillar

The main features of the second pillar are:

1. Mandatory occupational pension plan
2. Services:

• BVG (Federal Law on Occupational Retirement, Survivors and Disability Pension Plans, mandatory, represented by pension funds)
• UVG (Federal Law on Accident Insurance, compulsory)
• FZG (vested benefits on leaving or changing a pension fund)
• Non-mandatory insurance for the BVG as well as for the UVG

3. Objective: Maintaining the standard of living in old age and providing coverage in the event of disability and for dependents in the event of death (in combination with the first pillar).
4. Funding: funded (savings)

Features of the occupational pension plan (BVG)

The second pillar is divided into two parts: the mandatory and the extra-mandatory part. In the mandatory part, the annual income that is insured is limited. The extra-mandatory part is the part above that limit.

In the mandatory area, the pension plan covers the Protection in old age (BVG pension) as well as services for Disability and survivors’ insurance. It also includes vested benefits (assumption of claims in the event of a change of benefits provider). Continued payment of wages in the event of illness, by contrast, is covered by separate, voluntary daily sickness benefits insurance and is not part of the BVG mandatory scheme. The second pillar is supplemented by accident insurance (UVG), which covers employees against the risks of occupational and non-occupational accidents and work-related illnesses.

As soon as the annual salary subject to OASI exceeds the BVG minimum annual salary, employees are required to pay BVG contributions and insurance. The employers are responsible for the correct insurance in the BVG. As with the OASI contributions, they pay at least half of the contributions. Self-employed persons pay into the BVG voluntarily. The capital is managed by public and private pension funds.

The obligation to insure is thus limited to income in the mandatory area. Above it, a pension fund insures only what its own regulations provide for. That part is called extra-mandatory provision, or pension 2b, and it still belongs to the second pillar, not the third. Contributions to occupational provision reduce taxable income, and the accumulated capital is not taxed as wealth until it is paid out.

Pillar 3: Private pension provision, the supplement for the accustomed lifestyle

The benefit objective of around 60 percent refers to the mandatory part. It stops at an annual salary of CHF 90,720 (in force since 1 January 2025, unchanged in 2026). Anything above that is not insured under the mandatory scheme. Extra-mandatory arrangements cover more; how much is set out in each pension fund’s regulations and cannot be stated as a general figure. On top of this come demographic trends: in the future, far fewer working people in Switzerland will have to pay for the benefits of more and more pensioners.

The further the mandatory scheme’s benefit objective sits from the last salary, the larger the share the third pillar has to carry.

Features 3rd pillar

The main features of the third pillar are:

1. voluntary private provision
2. Benefits: the Federal Constitution anchored the third pillar as a principle in 1972. Its present division took shape only with the implementing law:

• Pillar 3a (a tied pension plan, tax-deductible with restrictions; in certain cases, such as the purchase of a home or the start of a self-employed business, the capital can be withdrawn early)
• Pillar 3b (free pension provision, fewer restrictions, no dedicated deduction, only the general insurance deduction, financial risks due to disability or death can be covered more in line with needs)

Features of private pension provision

Voluntary private provision rests on a wide range of financial products. As can be seen above, the third pillar is divided into a tied pension plan (3a), which is available to all employed persons and persons subject to OASI contributions in Switzerland, and a free pension plan (3b).

1. Pillar 3a (tied pension plan)

• As the name suggests, the capital saved in pillar 3a products is tied up and can only be withdrawn early in a few defined exceptional cases.
• The contributions are tax-deductible within annually defined limits. In 2026, these amount to CHF 7,258 for employed persons with a pension fund and up to 20 percent of earned income for employed persons without a pension fund, up to a maximum of CHF 36,288.
• Tax incentives also include the fact that the income is tax-free during the term and the capital saved for pension purposes is not subject to wealth tax. In addition, the early payout of the capital is taxed at a reduced special rate.
• Payment can be made no earlier than five years before reaching OASI retirement age.
• If employment is continued beyond the regular retirement date, receipt can be postponed by up to five years.
• Pillar 3a pension provision is often represented by classic products such as pension accounts and pension custody accounts.
• Paid pensions are fully taxed by the federal government as well as the cantons.

2. Pillar 3b (untied pension plan)

• The free pension plan 3b is not subject to any state requirements such as payments, availability, or payout dates. This means that the pension gap can be closed completely and individually.
• The pension plan can be geared to achieving personal savings goals and wishes at self-determined dates, for example. There are no government restrictions on deposits, withdrawals, or payout dates. The relevant contractual provisions of the financial product are exclusively authoritative.
• The unrestricted pension plan can be used by all persons living in Switzerland.
• Contributions to unrestricted provision can only be deducted within the general insurance deduction. That deduction also covers premiums for health and accident insurance, which often means the maximum has already been exhausted.
• If the statutory regulations are complied with, no taxes are payable on the lump-sum payment of periodically financed endowment life insurance policies. For this purpose, the contract must have been in force for at least five years and must have been concluded before the age of 66. In addition, the capital may not be paid out until after age 60.
• Compared to pensions from pillar 3a, which are fully taxable, pensions from the free 3b pension plan are now taxed only on a reduced, interest-rate-dependent income share (a change introduced in 2025; previously a flat 40 percent).

Unrestricted provision 3b: individual choice through a wide range of financial products

The ratio of pay-as-you-go to funded pension provision will continue to shift due to demographic developments, rising wages, and higher life expectancy. For the 3-pillar principle, this means that private provision in the third pillar will gain in importance. Pillar 3b is the least regulated form of provision: no contribution ceilings, and unlike pillar 3a its capital is not tied until the reference age. In return, its contributions are deductible only within the general insurance deduction, which health insurance premiums often exhaust on their own.

Besides banks, fintechs also offer products for unrestricted provision. The range runs from account solutions through securities-based saving to insurance-based arrangements. The choice of investment type depends on the investment horizon and on risk capacity.

The most important forms of investment in the area of unrestricted pension provision are:

• Savings account
• Stocks
• Bonds
• Funds
• Commodity funds (e.g. gold)

Spot pension gaps early and adjust the form of provision

Everyone’s requirements are individual. What is certain, however, is that once a standard of living has been achieved, people are reluctant to give it up. You should bear this in mind when planning your retirement provision. The benefit objective of the first two pillars refers to the mandatory insured part of the salary, and that part stops at CHF 90,720. Anyone earning more has a gap in the mandatory scheme, and it widens as the salary rises. Its size is shown on the pension fund statement.

In addition, make sure to adapt your pension plan to personal changes. These are, for example:

• Start of self-employed activity
• Divorce
• Family (children)
• Homeownership formation
• Early retirement

The provider market has responded to the challenges. So you can call on professional help for your retirement planning. Digitization has made wealth planning at “family office level” accessible to broad sections of the population.

The strengths of the Swiss pension system in an international comparison

The quality of pension systems was measured for years by HelpAge International’s Global AgeWatch Index, which ranked countries according to the situation and well-being of their older population. In its last edition, in 2015, Switzerland ranked first among the 96 countries surveyed. The index has not been published since; however, Switzerland also performs consistently well in more recent international comparisons of old-age provision systems.

The Swiss model has stood since 1948. The mandatory second pillar followed in 1985 with the BVG, and tied pillar 3a in 1987 with BVV 3. What distinguishes it from other systems is that the three pillars are financed differently and therefore complement each other:

• The OASI runs on a pay-as-you-go basis: today’s working population pays today’s pensions. The maximum pension is exactly twice the minimum, however much more has been paid in.
• Occupational provision runs on a funded basis: each insured person builds up their own capital. Demographic shifts therefore affect it less directly.
• Private provision in the third pillar is voluntary and tax-privileged during working life. Pillar 3a is tied to the reference age for that reason; pillar 3b is not.

Another feature of the Swiss welfare state is that supplementary benefits are paid to people who cannot build up savings or whose income is below the subsistence level.

That a pay-as-you-go system and a funded system sit side by side is the core of the construction: the two react differently to population change and inflation, and neither carries the load alone. Responsibility is spread too. The state organises the OASI, employers and employees carry the second pillar together, and the third remains voluntary.
