Third pillar in Switzerland: how can you secure extra retirement income?

What is the third pillar, and why does it matter to Hungarian readers?

The Swiss pension system is built on three pillars:

Together, the first and second pillars cover 60–70% of the last active salary according to Swiss statistics — this is the so-called “target level” (Leistungsziel). The third pillar is there to make up the difference.

Why is this especially important for Hungarians? Anyone who moves to Switzerland as an adult will have only partial contribution years in AHV. To qualify for the full Swiss AHV pension, 44 contribution years are required (for both women and men, since 2024). If someone arrives at 35 and works until 65, they will have 30 contribution years — and their AHV pension will be proportionally lower. The third pillar can partly compensate for this shortfall.

What’s more, savings accumulated in Switzerland — unlike some parts of the second pillar — can be handled more flexibly when returning home as well (see the payout rules below).

Third pillar 3a and 3b: how do they differ, and which one should you choose?

There are two forms of the third pillar, and they follow fundamentally different logic.

What is 3a (restricted savings / gebundene Vorsorge)?

The 3a account is strictly regulated: the annual contribution limit is set by law, the money can only be withdrawn in specific cases, and the range of investment options is limited. In return, the amount paid in is fully deductible from taxable income — this is the main attraction of this form.

What is 3b (free savings / freie Vorsorge)?

3b is not tied down: any life insurance, securities account, or bank deposit can fall under it. There is no annual limit and no restricted use. The tax benefit, however, is limited or varies by canton — in some cantons a partial deduction is possible, in others not.

Which one should you choose?

For most employees living in Switzerland, 3a is the primary tool, because the tax savings can be realized immediately and predictably. Pillar 3b is more relevant if someone has already used up the annual limit for Pillar 3a, or needs a level of flexibility that Pillar 3a does not provide (e.g. access at any time).

How much can be paid in, and how much tax relief is available in 2026?

Annual contribution limits

⚠️ I am flagging the figures below for human review in the INTERNAL NOTES block, because the Federal Social Insurance Office (BSV/OFAS) indexes these amounts every year.

How much tax can you actually save?

The amount saved depends on your marginal tax rate and the canton. In Switzerland, income tax is made up of federal, cantonal, and municipal components — together these range from 20–40% depending on the canton and income level.

A rough example (Zürich canton, 80 000 CHF gross annual income, calculated with 2026 tax rates):

• Pillar 3a contribution paid: 7 258 CHF

• Estimated tax savings: ~1 800–2 200 CHF (depending on the canton)

This means the actual “net cost” of the 7 258 CHF contribution is roughly 5 000–5 500 CHF — the rest comes back as a tax refund.

Important: the amount saved can vary significantly from canton to canton. In low-tax cantons such as Zug or Nidwalden, the absolute savings are smaller than in Genève or Vaud, where the marginal rate is higher.

Tax exemption during the accumulation period

On the capital held in a Pillar 3a account, no wealth tax (Vermögenssteuer) is due, and interest, dividends, and capital gains are also not taxable during the accumulation period. This is especially valuable if the account is invested in equity funds.

Who is eligible for a Pillar 3a account?

Eligibility depends on two conditions:

1. Swiss residence (Wohnsitz in der Schweiz): the person must live in Switzerland and be liable to tax there.

2. Income from employment or self-employment (Erwerbseinkommen): the maximum contribution may not exceed the earned income for that year.

As a Hungarian citizen: if with a B permit (Ausländerausweis B)If you live and work in Switzerland with a C permit (Niederlassungsbewilligung C), you are fully eligible. Holders of an L permit (short-term stay, Kurzaufenthaltsbewilligung L) can also open the account, but the rules for early withdrawal may differ — it is worth clarifying this with the specific financial institution.

Who is not eligible: retirees, unemployed persons (except if they receive unemployment benefits, which in some cases count as earned income — ⚠️ human review required), or persons who are not taxable in Switzerland.

Step by step: how do you open a third pillar account?

The process is simpler than many people think. The steps below apply to opening a bank 3a account (the procedure is different for insurance-based solutions).

1. Choose a provider. A 3a account can be opened at a bank or with an insurance company. With a bank solution, the money grows through bank deposits or investment funds; with an insurance solution, the product is combined with life insurance.

1. Gather the required documents.

- Valid identity document (passport or ID card) - Residence permit (if you are not a Swiss citizen) - Swiss tax identification number (AHV number / Sozialversicherungsnummer)

1. Fill out the account-opening application. This can be done online (at most digital banks and fintech providers) or in person at a branch.

1. Choose the investment strategy. Bank deposit (low risk, low return) or equity fund (higher risk, higher expected long-term return). This decision should be made based on the number of years remaining until the planned withdrawal date.

1. Set up a standing transfer. Most providers allow monthly or annual contributions. The annual limit cannot be split across multiple accounts — but you can open multiple 3a accounts with the same or different providers, and the total contributions together may not exceed the annual maximum.

1. Declare it in your tax return. Each year, the amount paid in must be reported in the cantonal tax return (Steuererklärung). The bank or insurance company issues a certificate (Bescheinigung), which must be attached.

Investment options and costs: what should you compare?

Bank 3a account vs. insurance-based 3a solution

Investment funds within the 3a account

Many banks offer 3a accounts linked to equity funds (e.g. a portfolio with an 80% equity / 20% bond allocation). The annual management fee (TER, Total Expense Ratio) ranges from 0.2–0.8%, depending on the provider and the fund. Digital providers (e.g. fintech platforms) generally use a lower fee structure than traditional large banks.

In the long run, the fee difference is significant.Over a 30-year accumulation period, a 0.5% annual fee difference means losing 10–15% of the final capital (due to the effect of compound interest).

Withdrawal rules: when and how can the money be taken out?

The 3a account is tied up — the money cannot be withdrawn at any time. The law (BVG/LPP and related ordinances) allows payout in the following cases:

Especially important from a Hungarian perspective: in the event of permanent departure

If you move back to Hungary (or another EU country) and your Swiss tax residency ends, you must withdraw the 3a account — you cannot leave it “sitting” in Switzerland indefinitely. When paid out, Switzerland deducts withholding tax (Quellensteuer), the rate of which varies by canton (typically around 5–10%, but this should be verified — ⚠️ human review required). Under the Hungarian-Swiss double taxation agreement (1981, with amendments), this amount cannot be taxed again in Hungary — but it must be documented in the tax return.

Taxation upon payout

The paid-out amount is taxed at a separate tax rate (Kapitalauszahlungssteuer), which is lower than the regular income tax. The tax rate varies by canton. If you have multiple 3a accounts, it is strategically advantageous to spread the payouts across different tax years — this reduces the amount taxed at once.

Common questions and frequent pitfalls

What are the most common mistakes?

1. Starting too late. The earlier you start contributing, the more compound interest works in your favor. Someone who starts at 30 and contributes CHF 7,000 a year until age 65 (approximate figure) will build up a significantly larger capital than someone who starts at 45.

2. Keeping the money only in a bank deposit. Over the past decade, interest on traditional 3a bank deposits has typically been around 0–0.5%. Over a long accumulation period, a solution linked to an equity fund has historically delivered higher real returns — but this comes with investment risk.

3. Buying an insurance product without flexibility. Some 3a products combined with life insurance tie up the saver for a long contractual term. If you cancel early, a surrender loss may arise.

4. Not spreading out the payouts. If you withdraw your 3a capital as one large lump sum, a higher tax rate may apply. With multiple accounts, staggered withdrawals over several years can be more tax-efficient.

5. Not declaring it in the tax return. The tax deduction for contributions is not automatic — you have to claim it actively. If you miss this, you lose the benefit for that year (there is a limited possibility of retroactive corrections — ⚠️ human review required).
