What every family should know about the 3rd pillar.
The Swiss 3rd pillar is private, voluntary retirement saving. Pillar 3a is tax-deductible and locked in until close to retirement; Pillar 3b is fully flexible but not tax-privileged in most cantons. For most families and expats with taxable Swiss income, Pillar 3a is one of the most efficient long-term financial tools available.
Why the third pillar exists
State and occupational pensions are both capped. The higher the salary, the larger the share of income the first two pillars do not replace — and that uncovered space is what the third pillar is designed for.
Two pillars are fixed. The third is up to you.
The bar is your salary. Move the dial and watch what the first two pillars do — and what they stop doing.
See where the first two pillars stop.
- 1st pillar — AHV/AVSLocked · set by the state
Covers basic living costs — and pays out a capped maximum, however much you earned.
- 2nd pillar — BVG/LPPLocked · set by your employer
Built with your employer — but only insures salary up to a legally defined limit.
- 3rd pillar — 3a & 3bOpen · set by you
Voluntary, tax-privileged in Pillar 3a — and the only layer with no ceiling above it.
Illustrative proportions, not a pension forecast. The ceilings are real: AHV pays a capped maximum pension and the 2nd pillar only insures salary up to a defined limit.
Two pillars are fixed. Pillar 3 is the only place where your decision changes the number.
- Pillars 1 & 2
- Mandatory. AHV is paid for by today's workers, your pension fund by you and your employer — neither adapts to what you will actually need.
- Pillar 3
- Voluntary, and 3a is the tax-privileged version: every franc you pay in lowers this year's taxable income.
The third pillar comes in two forms
Before putting a number on it, one distinction matters: the tied Pillar 3a, which is tax-privileged, and the free Pillar 3b, which is not.
- Pillar 3a (tied)
- Yes, up to the annual maximum
- Pillar 3b (free)
- Generally no (some cantonal exceptions)
- Pillar 3a (tied)
- Locked in until roughly 5 years before retirement
- Pillar 3b (free)
- Anytime
- Pillar 3a (tied)
- Set annually by federal law
- Pillar 3b (free)
- No cap
- Pillar 3a (tied)
- Home purchase, self-employment, emigration, 2nd-pillar buy-in, full disability
- Pillar 3b (free)
- No restrictions
- Pillar 3a (tied)
- Reduced separate rate, split across accounts helps
- Pillar 3b (free)
- Depends on product (e.g. life insurance)
- Pillar 3a (tied)
- Long-term retirement building block
- Pillar 3b (free)
- Flexible saving, gifts, estate planning
| Pillar 3a (tied) | Pillar 3b (free) | |
|---|---|---|
| Tax-deductible contributions | Yes, up to the annual maximum | Generally no (some cantonal exceptions) |
| Access to funds | Locked in until roughly 5 years before retirement | Anytime |
| Contribution cap | Set annually by federal law | No cap |
| Withdrawal reasons before retirement | Home purchase, self-employment, emigration, 2nd-pillar buy-in, full disability | No restrictions |
| Taxation at withdrawal | Reduced separate rate, split across accounts helps | Depends on product (e.g. life insurance) |
| Typical use case | Long-term retirement building block | Flexible saving, gifts, estate planning |
What Pillar 3a is worth on your tax bill
Every franc you pay into Pillar 3a reduces your taxable income for the year, at federal, cantonal and communal level. Depending on your canton and marginal tax rate, the tax saving typically ranges between roughly 20% and 40% of the amount contributed. Assets inside the account are also exempt from wealth tax and no income tax is due on interest or investment gains while the money is tied.
At withdrawal, a reduced separate rate applies, typically well below ordinary income tax. The exact effect depends on your canton, commune and civil status.
An indicative figure for your income range takes about a minute.

Two annual maximums are set by federal law each year:
- Small maximum — for employees affiliated to a 2nd-pillar pension fund.
- Large maximum — for self-employed people without a 2nd pillar, expressed as a percentage of net income up to a cap.
The exact amounts are updated periodically. Contributions must be received by 31 December of the tax year to qualify. From 2025, retroactive contributions for missed years are gradually being allowed under new federal rules — worth checking each year before you plan.
When you get the money back
Pillar 3a is a long-term product. In addition to ordinary retirement withdrawal, the law allows early withdrawal in a limited set of situations:
- Purchase or amortisation of owner-occupied property (main residence).
- Becoming self-employed as a main occupation.
- Permanently leaving Switzerland.
- Buying additional years into your 2nd-pillar pension fund.
- Receiving a full disability pension.
Bank or insurance — the two ways to hold a 3a
Pillar 3a can be held with a bank (including securities-based 3a) or with a life insurer. Both are recognised under Swiss law and both qualify for the annual tax deduction up to the federal maximum. They differ in structure, not in status.
- Bank 3a (incl. securities 3a)
- Bank or fund provider
- Insurance 3a
- Life insurance company
- Bank 3a (incl. securities 3a)
- Freely chosen each year, up to the annual maximum
- Insurance 3a
- Fixed premium schedule agreed in the policy
- Bank 3a (incl. securities 3a)
- Cash account or securities portfolio (funds)
- Insurance 3a
- Guaranteed component and/or unit-linked component
- Bank 3a (incl. securities 3a)
- Not included — arranged separately if desired
- Insurance 3a
- Integrated within the policy (death, disability, premium waiver)
- Bank 3a (incl. securities 3a)
- Pause or resume contributions any year
- Insurance 3a
- Contractual commitment for the policy term
- Bank 3a (incl. securities 3a)
- Account or fund management fees
- Insurance 3a
- Insurance premium including risk and cost components
- Bank 3a (incl. securities 3a)
- Yes, up to the annual 3a maximum
- Insurance 3a
- Yes, up to the annual 3a maximum
- Bank 3a (incl. securities 3a)
- Standard Pillar 3a rules
- Insurance 3a
- Standard Pillar 3a rules, plus policy-specific surrender terms
| Bank 3a (incl. securities 3a) | Insurance 3a | |
|---|---|---|
| Provider type | Bank or fund provider | Life insurance company |
| Contributions | Freely chosen each year, up to the annual maximum | Fixed premium schedule agreed in the policy |
| Investment | Cash account or securities portfolio (funds) | Guaranteed component and/or unit-linked component |
| Life / disability cover | Not included — arranged separately if desired | Integrated within the policy (death, disability, premium waiver) |
| Flexibility | Pause or resume contributions any year | Contractual commitment for the policy term |
| Fees | Account or fund management fees | Insurance premium including risk and cost components |
| Tax deduction | Yes, up to the annual 3a maximum | Yes, up to the annual 3a maximum |
| Withdrawal rules | Standard Pillar 3a rules | Standard Pillar 3a rules, plus policy-specific surrender terms |
Both solution types can coexist. Some households hold a bank 3a alongside an insurance 3a to combine savings flexibility with integrated risk cover. Which combination fits depends on individual circumstances, and both are compared impartially during a consultation.
The 3rd pillar for expats
Expats with Swiss earned income can generally open a Pillar 3a account from their first year of Swiss taxation. If you are taxed at source, the 3a deduction is normally claimed by filing a rectification (Tarifkorrektur / rectification of the withholding tax). If you leave Switzerland permanently, you can withdraw the balance — usually taxed at a favourable rate in the canton where the account provider is domiciled.
The 3rd pillar for families
For families, the 3rd pillar plays two roles: long-term saving with strong tax efficiency, and a source of equity for a future home purchase. Each spouse with Swiss income can contribute up to the full 3a maximum in their own name — meaning a working couple can effectively double the household deduction.
- Each spouse with Swiss earned income can hold their own Pillar 3a account.
- Contributions can be split across multiple 3a accounts held with different providers.
- Pillar 3a assets can be used towards owner-occupied property under the WEF/EPL rules.
- Both bank 3a and insurance 3a qualify for the annual tax deduction up to the federal maximum.
