Pillar 3a for Expats in Switzerland: The Complete 2026 Guide
When I ask expats what they wish they'd done differently in their first year in Switzerland, the answer is almost always the same: "I should have started my 3a immediately."
Not because it's a complex product. It's actually the simplest financial decision you can make in Switzerland. But because every year you don't contribute, you leave CHF 1,500–2,500 in tax savings on the table. Gone. Unrecoverable — until 2026, when the rules changed. More on that later.
This guide covers everything you need to know about Pillar 3a as an expat: who's eligible, how much you can contribute, how much tax you save, bank vs. securities, what happens when you leave Switzerland, and the brand-new retroactive contribution rules for 2026. Whether you arrived last week or five years ago, there's something here for you.

What is Pillar 3a — and why expats should care
Switzerland's pension system rests on three pillars. The first two are mandatory — state pension (AHV) and occupational pension (BVG). The third is voluntary, private, and tax-advantaged. That's Pillar 3a.
Here's why it matters: every franc you put into 3a is fully deducted from your taxable income. At a marginal tax rate of 25–35% (typical for expats in Zurich, Geneva, or Basel), that's an immediate "return" of 25–35% in the form of tax savings — before any investment return.
No other financial product in Switzerland offers this. Not your savings account. Not your ETF. Not crypto. Pillar 3a is the single most powerful tool in the Swiss financial system for anyone who earns AHV-liable income.
Think of 3a as the Swiss government paying you to save for retirement. You contribute CHF 7,258. You save ~CHF 2,200 in taxes. Your effective cost: ~CHF 5,000. And the full CHF 7,258 is yours — including when you leave Switzerland.
For expats, there's an additional benefit: you can withdraw the entire 3a balance when you permanently leave Switzerland. This makes it not just a retirement tool, but a tax-efficient savings vehicle for anyone who plans to live in Switzerland for 3+ years.
Who's eligible (spoiler: almost every expat)
The rule is simple: anyone who earns income subject to Swiss AHV contributions can contribute to Pillar 3a. This includes:
| Status | Eligible? | Notes |
|---|---|---|
| Employed with B-permit | Yes | Most common expat situation. Full eligibility. |
| Employed with C-permit | Yes | Same as B-permit for 3a purposes. |
| Employed with L-permit (short-term) | Yes | As long as you pay AHV contributions. |
| Cross-border commuter (G-permit) | Yes | If subject to Swiss AHV. |
| Self-employed | Yes | Higher limit: up to CHF 36,288/year (if no 2nd pillar). |
| Unemployed (receiving ALV) | Yes | ALV counts as AHV-liable income. |
| Not working / no AHV income | No | No AHV income = no 3a eligibility. |
Key point for new arrivals
The annual 3a maximum is not pro-rated for partial years. If you move to Switzerland in September and start earning AHV income, you can still contribute the full CHF 7,258 for that calendar year — as long as the payment reaches your 3a account by 31 December. Don't wait until January. Open an account immediately.
How much you can contribute — and how much tax you save
2026 contribution limits
| Category | Max. annual contribution | Per month |
|---|---|---|
| Employed with pension fund (2nd pillar) | CHF 7,258 | ~CHF 605 |
| Self-employed without pension fund | CHF 36,288 (20% of net income) | ~CHF 3,024 |
Tax savings by canton (on CHF 7,258 contribution)
Your tax savings depend on your marginal tax rate, which varies by canton, municipality, income level, and marital status. Here are estimates for the most common expat cantons at a taxable income of CHF 100,000 (single, no children):
| Canton | Approx. marginal rate | Approx. annual tax savings |
|---|---|---|
| Zurich | ~30% | ~CHF 2,177 |
| Geneva | ~33% | ~CHF 2,395 |
| Basel-Stadt | ~32% | ~CHF 2,323 |
| Vaud | ~34% | ~CHF 2,468 |
| Zug | ~22% | ~CHF 1,597 |
| Schwyz | ~20% | ~CHF 1,452 |

The maths over 10 years
If you contribute CHF 7,258 per year for 10 years in Zurich, you save approximately CHF 21,770 in taxes alone. That's before any investment return on the capital. At 5% annual return (securities-based 3a), your 3a balance after 10 years is approximately CHF 94,000 — of which CHF 21,770 came from tax savings you would have otherwise paid to the canton. This is free money. There is no other product in Switzerland that does this.
Bank account vs. securities: the CHF 100,000+ difference
You have two choices for your 3a: a savings account or a securities solution (invested in stocks/bonds). This is the most important decision — and most expats get it wrong by defaulting to the savings account.
| Factor | 3a Savings Account | 3a Securities (invested) |
|---|---|---|
| Interest/return | ~1.0% (2026) | ~5–7% long-term average |
| Risk | No market risk | Market fluctuations, but historically positive over 10+ years |
| After 10 years (CHF 7,258/yr) | ~CHF 76,000 | ~CHF 94,000–100,000 |
| After 20 years | ~CHF 160,000 | ~CHF 250,000–280,000 |
| Difference over 20 years | CHF 90,000–120,000 more with securities | |
| Best for | Leaving Switzerland within 1–3 years | Staying 3+ years or until retirement |
The rule of thumb
If you're staying in Switzerland for 3+ years, invest your 3a in securities. The tax savings are identical either way — but the investment return over time creates a six-figure difference. A securities-based 3a with 60–99% equities is appropriate for anyone with a 10+ year horizon. If you're leaving within 1–2 years, a savings account avoids short-term market risk.

Choosing a 3a provider: what matters
For a securities-based 3a, the main providers for expats in Switzerland are:
| Provider | Total cost (TER + fees) | Max. equity allocation | Approach |
|---|---|---|---|
| arvy ⭐ | 0.84–1.11% | 100% (Climbing) | Actively managed quality stocks — ~30 hand-picked companies, founders co-invest, weekly education |
| Finpension | 0.39% | 99% | Passive ETF-based |
| VIAC | 0.44% | 99% | Passive ETF-based |
| frankly (ZKB) | 0.45–0.48% | 95% | Passive ETF-based, bank-backed |
| True Wealth | 0.40% | 99% | Passive ETF-based |
Why arvy 3a is different
Most 3a providers give you a passive ETF portfolio with 1,500+ anonymous companies. arvy's 3a is actively managed by 3 CFA Charterholders who invest their own money — six figures — in the same portfolio as yours. You get ~30 hand-picked quality companies (Visa, LVMH, Microsoft, L'Oréal, Nestlé…) that you actually understand, plus a weekly company analysis (arvy Weekly, 12,000+ readers). Higher fees than passive ETFs — but you get quality selection, education, and skin-in-the-game alignment you won't find anywhere else. → Open your arvy 3a
arvy 3a strategies
arvy offers five 3a strategies with different equity allocations, named after a walking metaphor — from gentle to adventurous:
| Strategy | Equity allocation | Best for |
|---|---|---|
| Strolling | ~25% | Conservative, short horizon or close to retirement |
| Walking | ~45% | Balanced with lower volatility |
| Hiking | ~65% | Balanced growth with meaningful stability |
| Mountaineering | ~80% | Growth-oriented, 10+ year horizon |
| Climbing | ~100% | Maximum long-term growth, 15+ year horizon |
The rule of thumb: For expats staying 3+ years with a 10+ year investment horizon, Climbing or Mountaineering typically makes the most sense. The long horizon lets you ride out market volatility while benefiting from compound growth on quality companies.
NEW in 2026: Retroactive contributions
This is the biggest change to Pillar 3a since it was introduced in 1987. Starting 1 January 2026, you can make up missed 3a contributions from previous years — up to 10 years back.
How it works
1. The catch-up only applies to contribution years from 2025 onwards. Gaps from 2024 and earlier cannot be recovered.
2. You must first pay the full regular 3a amount for the current year (CHF 7,258 in 2026) before making any catch-up payment.
3. You must have had AHV-liable income in the year you're catching up for.
4. Catch-up contributions are fully tax-deductible, just like regular contributions.
5. The first catch-up is possible in 2026, for the gap year 2025.
Example
You arrived in Switzerland in August 2025 and contributed CHF 3,000 to your 3a (instead of the maximum CHF 7,258). Gap: CHF 4,258. In 2026, you can: pay the regular CHF 7,258 for 2026 AND pay CHF 4,258 as a catch-up for 2025. Total 3a deduction in 2026: CHF 11,516. At a 30% tax rate, that saves you ~CHF 3,455 in taxes — in a single year.

What happens when you leave Switzerland
This is the question every expat asks — and the answer is good news.
The key rule
You can withdraw your entire 3a balance when you permanently leave Switzerland. There is no penalty. There is no minimum holding period. The money is 100% yours from day one.
However, there's a withdrawal tax — and it varies significantly by canton:
| Canton of withdrawal | Approx. tax on CHF 50,000 withdrawal | Approx. tax on CHF 100,000 withdrawal |
|---|---|---|
| Schwyz | ~CHF 2,000 (4.0%) | ~CHF 4,500 (4.5%) |
| Zug | ~CHF 2,400 (4.8%) | ~CHF 5,200 (5.2%) |
| Zurich | ~CHF 3,000 (6.0%) | ~CHF 7,000 (7.0%) |
| Basel-Stadt | ~CHF 3,500 (7.0%) | ~CHF 8,000 (8.0%) |
| Geneva | ~CHF 3,800 (7.6%) | ~CHF 8,500 (8.5%) |
| Vaud | ~CHF 4,000 (8.0%) | ~CHF 9,500 (9.5%) |
Note: Rates are approximate and depend on municipality, marital status, and other factors. The withdrawal tax is separate from income tax and is applied at a reduced rate.
Expat strategy: the multiple-accounts trick
If you accumulate CHF 100,000+ in 3a over several years, split it across 3–5 different 3a accounts and stagger your withdrawals across different tax years. Because the withdrawal tax is progressive, withdrawing CHF 25,000 four times (in four years or upon departure) costs significantly less than withdrawing CHF 100,000 at once. This is legal, standard practice, and recommended by tax advisors.
Destination matters
Where you move to affects how your 3a withdrawal is taxed in your home country. Some countries (like Germany) may tax the withdrawal again under their domestic rules, while double taxation agreements (DTAs) usually prevent actual double taxation. If you're moving to the EU/EEA, your Pillar 2 (pension fund) may be partially blocked — but 3a is always withdrawable in full. Consult a cross-border tax advisor before leaving.
The multiple-accounts strategy
Sophisticated expats don't just open one 3a account. They open 3–5 — and here's why.
Reason 1: Tax optimisation at withdrawal. As explained above, the progressive withdrawal tax means multiple smaller withdrawals cost less than one large withdrawal. You can withdraw each account in a different year (e.g., one per year in the years before leaving).
Reason 2: Different investment strategies. You can put your first CHF 20,000 in a high-equity strategy (long-term growth) and later accounts in a more conservative strategy (if your departure date approaches).
Reason 3: Provider flexibility. You're not locked in. Different providers may offer different underlying funds, costs, or features. Having accounts at 2–3 providers gives you flexibility.
The maximum number of 3a accounts is not legally limited, but 3–5 is the sweet spot recommended by most tax advisors. The administrative overhead is minimal — most are managed through apps.
Beyond 3a: What to do with the rest
Pillar 3a is capped at CHF 7,258/year (~CHF 605/month). If you have more to invest — which most expats do — you need a plan for the surplus.
The order of priority:
1. Max out your 3a: CHF 605/month — tax-deductible, tax-sheltered growth, fully withdrawable on departure. Non-negotiable. With arvy's 3a, your money goes into the same ~30 quality companies that made the arvy team well-known.
2. Free investing: everything above CHF 7,258/year. This is where the arvy savings plan comes in — the same quality strategy, now in a tax-free wrapper (capital gains in Switzerland are tax-free). Your 3a and your savings plan work together: 3a for maximum tax efficiency, savings plan for unlimited contributions and flexibility.
The combination of arvy 3a + arvy savings plan is the most complete financial setup for expats who want quality, transparency, and skin-in-the-game alignment. Weekly analyses, 11 calculators, a book club, and a complete education library — all included. → How to invest CHF 500/month: the optimal allocation

Frequently Asked Questions
Can I contribute to 3a if I arrived mid-year?
Yes. The annual maximum is not pro-rated. If you arrive in September and earn AHV income, you can contribute the full CHF 7,258 for that year — as long as the payment is made by 31 December. Open your 3a account as soon as possible after arrival.
What if I have withholding tax — can I still deduct 3a?
Yes, but you need to request an ordinary tax assessment (ordentliche Veranlagung / TOU). This allows you to deduct your 3a contributions and other eligible expenses. For most expats, this results in a net tax refund. The request is free and can be done retroactively in some cantons. → Withholding tax guide
Can I contribute to 3a and invest with arvy at the same time?
Yes — and we recommend it. Your arvy 3a is your tax-efficient core (up to CHF 7,258/year). Your arvy savings plan is for everything beyond the 3a limit. Same quality philosophy, same ~30 hand-picked companies, same CFA team. The 3a gives you tax savings; the savings plan gives you unlimited contribution flexibility. → Learn about arvy 3a
What happens to my 3a if I die?
Your 3a is paid out to a defined order of beneficiaries: surviving spouse/partner first, then children, then parents, then other heirs. The payout is subject to the same reduced withdrawal tax. You can adjust the beneficiary order within the legal framework.
Can I withdraw 3a early for buying property?
Yes. You can withdraw or pledge your 3a for purchasing your primary residence in Switzerland. This is one of three early withdrawal triggers (the others being permanent emigration and becoming self-employed). If you're planning to buy, this can serve as your down-payment fund.
Should I use a bank or insurance 3a?
For most expats: a bank/securities 3a (not insurance). Insurance-based 3a products lock you into fixed premiums, have higher fees, and charge surrender penalties if you cancel early. Bank/securities 3a offers full flexibility: contribute any amount up to the maximum, skip years, change providers at any time, zero lock-in.
Is 3a really worth it if I'm only staying 3–5 years?
Yes — emphatically. In 5 years at CHF 7,258/year, you accumulate ~CHF 36,290 plus investment returns (~CHF 40,000 at 5%). You save ~CHF 10,900 in taxes over 5 years. When you leave, you withdraw the full balance minus ~5–8% withdrawal tax. Net benefit: ~CHF 8,000–9,000 in pure tax savings. No other product delivers this return.
What's the catch-up limit for retroactive contributions?
You can catch up missed contributions from up to 10 years back — but only for years from 2025 onwards. In 2026, you can catch up 2025 only. In 2027, you can catch up 2025 and 2026. The catch-up amount equals the gap between your actual contribution and the maximum for that year. You must first pay the full current-year maximum before making any catch-up. → Full retroactive contributions guide
