Third Pillar in Switzerland 2026: How Private Pension Saving Works

Updated: October 10, 2026

The Swiss pension system rests on three pillars. The first is the AHV (Old Age and Survivors’ Insurance), the state pension. The second is occupational pension provision through a pension fund. It’s mandatory for employees above a certain annual salary, but not for everyone who works. The self-employed, for example, can join voluntarily (FSIO, in German).

The third pillar is private pension provision. It’s voluntary: you decide whether, how much and where you save. Your employer has nothing to do with it.

Pillar 3a vs 3b

The third pillar has two parts:

Pillar 3a (restricted pension): The money generally stays tied up until shortly before retirement. In return, you can deduct your contributions from your taxable income.
Pillar 3b (unrestricted pension): This includes things like a savings account, a brokerage account or a life insurance policy. As a rule, there’s no deduction like with pillar 3a. You can still be tied in, for example through a long-term insurance contract.

This guide focuses on pillar 3a.

Who can contribute to pillar 3a

You can contribute if you have earned income subject to AHV contributions. If you’re employed, you start paying AHV contributions on 1 January after your 17th birthday (AHV fact sheet 2.01, in German). Apprentices and students with a side job can contribute too, and so can people receiving unemployment benefits (FSIO, in German). If you only live on support from your parents or on scholarships, you can’t.

After AHV reference age, you can only keep contributing if you’re still working, and for no more than five years.

Maximum contribution 2026

How much you can contribute depends on whether you’re a member of a pension fund. Whether you’re employed or self-employed isn’t what decides it.

With a pension fund: up to CHF 7,258 a year
Without a pension fund: up to 20% of your net earned income, i.e. your earned income after social security contributions, capped at CHF 36,288 a year

That’s according to the Federal Tax Administration’s overview and the canton of Schwyz fact sheet (both in German). If you’re employed but not in a pension fund because of a low salary, the 20% rule applies to you. With net earned income of CHF 20,000, that’s no more than CHF 4,000. If you’re self-employed and voluntarily joined a pension fund, the lower amount applies instead.

The maximum applies per person and year across all your 3a accounts combined. Having several accounts doesn’t let you contribute more.

The amounts rise from 2027: on 5 October 2026, the Federal Tax Administration announced CHF 7,373 with a pension fund and up to CHF 36,864 without one (announcement, in German). For contributions in 2026, the amounts above still apply.

Contribution deadline

You can contribute throughout the year or all at once. For a contribution to count for the current tax year, it must be credited to your 3a account by 31 December. A payment order placed on 31 December isn’t enough (ESTV circular 18a, in German). Some providers also set an earlier cut-off. So it’s best to pay in early December or before.

Catch-up contributions: new since 2026

If you didn’t contribute the full amount in a year, you can now make up the gap later. This has been possible since 2026 for gaps from 2025 onwards, going back up to ten years. You must have had earned income subject to AHV contributions both in the year of the gap and in the year you catch up. In the catch-up year, you first pay the full ordinary contribution. On top of that, you can catch up at most the lower maximum per year, so CHF 7,258 in 2026. This also applies if you’re not in a pension fund.

Catch-up contributions are also deductible from your taxable income. Once you’ve drawn retirement benefits from pillar 3a for the first time, catch-ups are no longer possible. Simply paying in more isn’t enough: you have to request the catch-up from your 3a provider and back it up with the required information. Ask them about the exact process (FSIO, in German, ESTV circular 18a, in German).

When you can withdraw

For retirement, you can withdraw your 3a savings at the earliest five years before your AHV reference age. Normally, they’re paid out at reference age. If you keep working, you can defer the withdrawal until you stop, but by no more than five years.

Earlier withdrawals are only possible in specific cases:

for owner-occupied housing, i.e. buying, building or paying down your mortgage
if you become self-employed and are no longer subject to mandatory occupational pension provision
if you leave Switzerland permanently
if you receive a full disability pension (IV) and the disability risk isn’t insured
in the event of death, when the beneficiaries receive the savings

You can also use your savings to buy into your pension fund. In that case, the money is transferred directly rather than paid out to you (FSIO, in German, ESTV circular 18a, in German).

Important for planning: a regular retirement withdrawal always closes the whole account. For owner-occupied housing, a partial withdrawal is possible, but only until five years before reference age. Within those last five years, a withdrawal for housing also closes the whole account (ESTV circular 18a, in German).

Account, insurance or securities

3a savings account: Your balance doesn’t move with the stock market. But if the interest rate is below inflation, you lose purchasing power. An account can suit money you plan to withdraw within a few years, for example shortly before retirement or buying a home.

3a insurance: It combines saving with cover for death or disability. You usually commit to premiums for many years, and if you exit early, the surrender value can be well below what you’ve paid in, because part of the premiums goes toward risk cover and costs (Generali example, in German). Costs are also hard to compare. If you need risk cover, a separate risk insurance is often easier to understand. If you already have a 3a policy, check what exiting would cost and what cover you’d lose before cancelling.

3a securities: Your money is invested in funds holding stocks and bonds. With a horizon of 20 years or more, stocks offer higher potential returns than an account. But they can also drop sharply, and returns are never guaranteed. So only choose as much stock as you could hold through a crash without selling.

Passive index funds are particularly cheap. Digital providers like finpension, VIAC, True Wealth and frankly rely on them, and banks now also offer passive or index-oriented 3a funds. Compare the total costs: fund costs, the provider’s management fee and any commissions. You’ll find the providers in detail in the pillar 3a comparison, and examples from UBS, PostFinance and Raiffeisen in the section on bank funds.

How much tax you save

You can deduct your contributions from your taxable income up to the maximum. As long as the money stays in pillar 3a, you pay neither income nor wealth tax on the balance and returns (canton of Schwyz fact sheet, in German). Tax only applies on withdrawal.

How much you save depends on your marginal tax rate, i.e. how heavily your last francs of income are taxed. A simplified example: your taxable income before the 3a deduction is CHF 75,000, and you contribute CHF 7,258 in 2026. That lowers it to CHF 67,742. At an assumed marginal tax rate of 25%, you save CHF 1,814.50.

That’s pure arithmetic, not a tax calculation for a specific place of residence. Your actual rate depends on your income, canton, municipality and marital status and can be much lower or higher. The best way to work out your own saving is the federal tax calculator.

How much you can build up

An illustration, not a forecast: you contribute CHF 7,258 at the end of each year for 40 years, and your investments return 5% a year after costs. You end up with around CHF 877,000. Of that, you paid in CHF 290,320; the rest is investment return.

The 5% is an assumption, not an expected or guaranteed return. Inflation and withdrawal tax aren’t included, and the maximum amounts change over time. The example mainly shows how much a long investment horizon matters.

Tax on withdrawal and multiple 3a accounts

On withdrawal, the full capital is taxed, contributions and returns alike. The tax is levied separately from your other income. How high it is depends on your canton, municipality, marital status and the amount withdrawn. Depending on the applicable tariff, a larger withdrawal can be taxed at a higher rate.

If you withdraw several pension capital sums in the same year, they’re added together. In the canton of Zurich, for example, this includes pension fund and vested benefits, and for married couples, both partners’ withdrawals (canton of Zurich, in German).

With several 3a accounts, you can spread withdrawals over different years and often save tax. How much depends on your situation. But you can’t simply split an existing account into several later (ESTV circular 18a, in German). So open several accounts early and spread your future contributions across them.

When pillar 3a is less worthwhile

With a low income, you pay little tax, so the deduction is worth less. Then it’s worth comparing pillar 3a with a regular brokerage account. There, your money is always available, and capital gains on private assets are generally tax-free, as long as you don’t count as a professional securities trader. Dividends and interest, however, are taxed as income, and the account counts toward your taxable wealth (Federal Act on Direct Federal Tax, in German, ESTV on wealth tax, in German). In pillar 3a, you pay fees instead, and on withdrawal the full capital including returns is taxed.

That doesn’t mean pillar 3a never makes sense for apprentices or students. Starting early builds a saving habit, and money that’s tied up is harder to spend on impulse. And since 2026, it’s been possible to fill gaps later when your income is higher, as long as you meet the conditions.

Conclusion

For most people with a medium or higher income, pillar 3a is one of the simplest ways to save tax and build retirement savings. Self-employed people without a pension fund can deduct especially large amounts thanks to the 20% rule. Check which maximum applies to you, pay in on time and open several accounts early. With a long horizon, there’s a lot to be said for low-cost securities solutions with passive funds. The pillar 3a comparison shows which providers are worth considering.
