Pillar 3a — Tax-Free Retirement Savings
Step by step
- 1
Understand the 3-pillar system
Pillar 1 (AHV) = state pension. Pillar 2 (BVG) = employer pension. Pillar 3a = voluntary private savings with tax benefits. Together they aim to maintain your standard of living in retirement.
- 2
Know the maximum contribution
Employees: CHF 7,258/year (2026). Self-employed without BVG: CHF 36,288/year. Contribute the maximum every year for the biggest tax saving.
- 3
Choose a provider
Banks: UBS, PostFinance, Raiffeisen (capital guaranteed, low returns). Digital: VIAC, frankly, finpension (invested in ETFs, higher long-term returns). The difference over 30 years is significant.
- 4
Open multiple accounts
You can split contributions across up to 5 accounts. At withdrawal, each account is taxed separately — staggered withdrawals reduce the one-time tax hit.
- 5
Withdrawal rules
Locked until 5 years before retirement age (60 for women, 60 for men). Early withdrawal allowed for: buying property, leaving Switzerland permanently, starting self-employment.

Claim the deduction
Declare your 3a contributions on your tax return (or correction request for Quellensteuer). The full amount is deducted from taxable income.
Why Pillar 3a is so powerful for expats
Every franc you contribute to Pillar 3a is deducted from your federal, cantonal and communal taxable income in the year of contribution. For a typical expat earning CHF 100,000 in Zurich and maxing out CHF 7,258, the tax saving lands around CHF 1,800–2,200 — money that would otherwise simply leave your account. Over a 30-year working career, compounded contributions and tax savings often exceed CHF 500,000.
Bank vs investment-based Pillar 3a
Traditional bank Pillar 3a accounts pay near-zero interest and lose value to inflation over long horizons. Investment-based 3a (VIAC, frankly, finpension) puts your contributions into low-cost equity ETFs — historically delivering 5–7% real returns over decades. For anyone with a 10+ year horizon, the difference is enormous. The trade-off is short-term volatility: equity 3a will drop in bad years.
Early withdrawal: when you can access the money
Pillar 3a is normally locked until 5 years before AHV retirement age. Early withdrawal is allowed only in specific cases: buying your primary residence in Switzerland, starting self-employment, permanently leaving Switzerland (for a non-EU destination in most cases), or buying into your Pillar 2 pension fund. Withdrawals for property or self-employment are taxed at a reduced one-time rate.
How much you save by canton — worked examples
The actual saving depends on your marginal tax rate, which depends on income, canton and commune. Illustrative estimates for a single employee maxing CHF 7,258 in 2026: at CHF 80,000 income, roughly CHF 1,100 saved in Zug city, CHF 1,650 in Zurich city, CHF 1,900 in Geneva city. At CHF 120,000 income: roughly CHF 1,500 in Zug, CHF 2,300 in Zurich, CHF 2,700 in Geneva. Married couples with CHF 200,000 combined income in Zurich typically save around CHF 2,400 per person maxing out.
Practical rules to claim it
Deadline: contribution must hit your 3a account by 31 December of the tax year. Bank transfers in late December occasionally settle in January — pay by 28 December to be safe. Proof: your provider issues a Steuerbescheinigung (tax certificate) in January. Attach it to your tax return. Quellensteuer: if you are taxed at source and earn below the cantonal threshold for ordinary assessment, request a Tarifkorrektur by 31 March. Staggering: open 3–5 accounts over your career and close them in separate years between age 60 and 70 to break the capital-withdrawal tax into multiple smaller tranches.

How much tax do I actually save?
Depends on your canton and income. At CHF 100k in Zurich, maxing out 3a saves roughly CHF 1,500–2,000 in tax per year. Use our tax calculator to see the exact impact.
Should I choose a bank or investment 3a?
For horizons over 10 years, investment-based 3a (VIAC, frankly, finpension) historically outperforms bank accounts significantly. For shorter horizons, a bank account is safer.
Can I contribute if I just arrived?
Yes — as soon as you start working and paying into AHV, you can open a 3a account and contribute. Do it in your first year.

File your annual tax return
Swiss tax is levied at three levels — federal, cantonal and communal — and either withheld from your salary at source (Quellensteuer) or assessed by your canton after you file a return. Which one applies to you depends on your permit, income and assets, and it changes the moment you cross the CHF 120,000 threshold or acquire a C permit.
