The 3rd pillar is Switzerland's voluntary private pension system. It's one of the best tax optimization tools available to Swiss residents, but choosing the wrong product can cost you tens of thousands of francs. Here's how to get it right.
Switzerland's retirement system has three pillars. The 1st pillar (AHV/AVS) is the state pension, mandatory for everyone. The 2nd pillar (BVG/LPP) is the occupational pension, mandatory for employees. The 3rd pillar is voluntary private savings designed to fill the gap between what pillars 1 and 2 provide and what you actually need in retirement.
The 3rd pillar comes in two flavors:
The priority is clear: max out pillar 3a first for the tax savings, then use pillar 3b (regular investing) for anything beyond that.
Pillar 3a is the most powerful tax optimization tool for Swiss residents. Every franc you contribute reduces your taxable income. Depending on your canton and marginal tax rate, this can save you 25-40% in taxes immediately.
Most common case. Maximum contribution regardless of income.
20% of net income, capped at CHF 36,288. Must not be affiliated with a pension fund.
Starting in 2026, you can make up missed pillar 3a contributions for up to 10 years back (only for gaps from 2025 onward). If you didn't max out your 3a in 2025, you can catch up in 2026 or any year until 2035. Conditions: you must first pay the full current-year contribution, you must have been employed in Switzerland during the gap year, and you must not have made an early retirement withdrawal. Each retroactive contribution is fully tax-deductible.
Contributing CHF 7,258 to pillar 3a with a marginal tax rate of 30%:
Over 30 years, that's CHF 65,000+ in tax savings alone, before any investment returns. If you invest the 3a in stocks (99% equity allocation via VIAC or Finpension), the compound growth on top of the tax savings is massive.
Every franc contributed is deducted from your taxable income. The higher your tax rate, the bigger the benefit.
Money inside your 3a account is exempt from wealth tax. In a regular brokerage account, your portfolio is taxed annually as part of your wealth.
Inside the 3a, dividends and capital gains accumulate tax-free. In a regular account, dividends are taxed as income every year.
This is the most important decision when opening a pillar 3a. There are two types of 3a products, and they are very different.
Offered by banks (PostFinance, Raiffeisen) and specialized pension foundations (VIAC, Finpension, frankly). You open an account, transfer money, and choose how to invest it (savings account or stock-based strategy).
Sold by insurance companies (Swiss Life, Axa, Helvetia, Zurich, Baloise) as "3a life insurance" or "combined 3a solutions." They bundle a savings product with life insurance and/or disability coverage into a single contract.
Insurance 3a products bundle savings and life/disability insurance into a single contract. This sounds convenient, but the combination is designed to benefit the insurer, not you:
The insurer's commission (often CHF 1,000-3,000+) is deducted from your first years of contributions. This is why your surrender value is often CHF 0 after the first year and barely positive for several years after. Your money pays the salesperson before it starts working for you.
Insurers argue that the binding contract forces you to save regularly. But discipline through penalty is not real discipline. A standing order to a bank 3a achieves the same thing without locking you into a 20-30 year contract. If your financial situation changes (job loss, reduced income, relocation), the insurance contract becomes a burden.
If you need life insurance or disability coverage, buy a standalone risk policy (assurance risque pure). It costs a fraction of the combined product and you keep full flexibility on the savings side. Mixing insurance and investment always benefits the insurer at your expense.
CHF 7,000/year contributed for 30 years, assuming 5% gross returns:
The difference: CHF 105,000 lost to higher fees over 30 years. And this doesn't account for the lower stock allocation in insurance products, which reduces returns further.
Because insurance companies have sales forces that actively sell these products. Banks and independent financial advisors earn high commissions (often CHF 1,000-3,000 per contract) for selling insurance 3a. The products are pitched as "safe" and "all-in-one," but the fine print reveals the true cost. If you've already signed one, check the surrender value before cancelling. Sometimes it's better to stop paying (make it "paid-up") and open a bank 3a alongside it.
Once you've decided on a bank/foundation 3a (the right choice for most people), here's what to compare:
The single most important factor. Even 0.3% difference compounds to thousands of francs over decades. Look for all-in fees below 0.50%. The best providers charge 0.00-0.40%.
If you have 15+ years until retirement, a high stock allocation (80-99%) gives you the best expected returns. Traditional bank 3a products often cap at 50-75%. Providers like VIAC and Finpension offer up to 99%.
Check what funds the provider uses. Low-cost index funds (tracking MSCI World, S&P 500, SPI) are ideal. Some providers use expensive proprietary funds that drag down returns.
You can open multiple 3a accounts (5 is the common recommendation for staggered withdrawals). Check if the provider supports this easily.
Up to 99% stocks, 0% product fees (only fund TER ~0.38%), Swiss pension foundation. Multiple accounts supported. App-based, simple to use.
Up to 99% stocks, low all-in fee, Swiss pension foundation. Multiple accounts supported. Strong customization options for investment strategy.
Up to 95% stocks. Backed by Zurcher Kantonalbank. Slightly higher fees but a solid option.
PostFinance, UBS, CS, Raiffeisen. Higher fees, lower max stock allocation (usually 45-75%). Only worth it if you specifically need a savings account 3a with capital guarantee.
Fees and offerings may change. Verify current rates on each provider's website before opening an account.
An important clarification first: in practice, "pillar 3b" almost always refers to insurance products. When a financial advisor or insurer says "3b," they mean a life insurance policy, not your brokerage account. Technically, any private savings outside of 3a falls under 3b (your ETF portfolio, savings account, etc.), but the term is used almost exclusively by the insurance industry to sell their products.
With that in mind: pillar 3b has no federal tax benefit. However, two cantons are exceptions: Geneva and Fribourg allow you to deduct 3b insurance premiums from your cantonal taxable income.
You can contribute more than these amounts, but only the amounts above are deductible. Anything above the cap gives you no tax benefit. In all other cantons, 3b has no tax deduction at all.
This deduction only applies to 3b held as insurance products, not bank or brokerage accounts. That means the same problems as insurance 3a apply: high fees, long-term lock-in, front-loaded commissions, and penalties for early cancellation. A CHF 2,200 deduction at 30% tax rate saves you CHF 660/year. If the insurance fees cost you more than that in lost returns, the deduction isn't worth it. Do the math carefully before signing.
Max out pillar 3a first (CHF 7,258 tax-deductible everywhere). Then invest everything beyond that in a regular brokerage account using low-cost, accumulating ETFs. Capital gains on securities are tax-free in Switzerland for private individuals, making a regular brokerage account already very tax-efficient. If you live in Geneva or Fribourg, run the numbers on a 3b insurance, but don't sign one just for the deduction without understanding the fees and lock-in.
When you withdraw your pillar 3a, the full amount is taxed as income at a reduced rate. The tax rate is progressive, meaning the more you withdraw in a single year, the higher the rate.
The solution: open multiple 3a accounts and withdraw them in different tax years. This is called staggered withdrawal.
Assume you have CHF 250,000 across your 3a accounts at retirement:
Saving: ~CHF 10,000 just by splitting into 5 accounts. Tax rates vary by canton. The general recommendation is to open 5 accounts throughout your career, contributing equally to each.
You can withdraw 3a funds before retirement only in specific cases:
Your 3a and 3b investments are a major part of your financial picture. Boring Money brings them together:

Start tracking your retirement savingsAs soon as you start earning taxable income in Switzerland. Even if you can't max out the full CHF 7,258, every franc contributed saves you taxes today and grows tax-free until retirement. Starting at 25 instead of 35 gives you 10 extra years of compound growth, which can mean CHF 100,000+ more at retirement.
First, request the current surrender value (Ruckkaufswert) from your insurer. Compare it to the total premiums you've paid. In the first 3-5 years, the surrender value is often 30-60% less than what you contributed (because of front-loaded acquisition costs). You have three options:
In all cases, open a bank 3a (VIAC, Finpension) immediately for all future contributions.
Yes, bank/foundation 3a accounts can be transferred to another provider at any time, usually for free. The transfer happens in kind (your investments are sold and rebought) or as cash. This is another advantage over insurance 3a, which cannot be transferred without cancelling.
If you have 10+ years until retirement, investing in stocks (high equity allocation) is almost always better. A 3a savings account currently earns 0.5-1.5% interest, which barely keeps up with inflation. A stock-based 3a historically returns 5-7% per year. Over 30 years, the difference is massive. Only keep your 3a in a savings account if retirement is less than 5 years away.
Yes, this is one of the early withdrawal exceptions. You can withdraw pillar 3a funds for the purchase of your primary residence (as a down payment or to pay off a mortgage). You can also pledge your 3a as collateral for a mortgage without withdrawing. The withdrawal is taxed at the reduced capital withdrawal rate. Note: once withdrawn for property, you can continue contributing to rebuild the account.
The common recommendation is 5 accounts. This allows you to stagger withdrawals over 5 tax years (from age 60 to 65), reducing the total tax burden. Some people open more, but the administrative overhead increases. Start with 1-2 accounts and add more over the years as your balances grow.
