Here’s the truth: If you’re a European expat in Switzerland, Germany, or the Netherlands and you’re blindly maxing out your Pillar 3a (or equivalent) every year, you might be leaving tens of thousands of euros of potential returns on the table.
Too many expats treat their Pillar 3a like a sacred cow. But with ETF investing becoming both easier and cheaper in Europe, it’s time to question the old orthodoxy. Should you really keep stuffing that Pillar 3a, or is it smarter to shift your spare cash into a globally diversified ETF portfolio instead?
The Bottom Line
Pillar 3a delivers tax breaks, but the tradeoff is liquidity and growth. In 2026, most mobile expats are better off blending ETF investments with only modest 3a contributions.
The Allure of Pillar 3a: Tax Relief With Strings Attached
Let’s start with the Pillar 3a basics. In Switzerland, the 2026 tax-deductible limit is CHF 7,350 for employees. Maxing it out sounds like a no-brainer, especially when Zurich’s top marginal rate is a punishing 40%. A full 3a contribution can slash your tax bill by up to CHF 3,000 per year depending on your bracket. That’s real money.
Over a decade, Swiss expats who max out their Pillar 3a could save CHF 20,000–30,000 in taxes — but they’re also locking away CHF 73,500 in assets, inaccessible until retirement or emigration.
Germany and the Netherlands offer similar incentives with Riester and private pension products, but the story is the same: the state rewards you up front, but demands patience and residency in return. And good luck getting at those funds early if your career takes you to Singapore or Dubai in five years.
You want more numbers? Annualized real returns for Swiss bank 3a accounts averaged a pathetic 0.4% (2013-2023). The best “investment” 3a funds — UBS Vitainvest, Swiss Life Index — barely cracked 3% after fees, constrained by regulation and home bias. Inflation? You’re losing ground.
ETFs: Flexibility and Growth for the Globally Mobile
This is where ETFs crush the Pillar 3a. Let’s say you choose a low-cost, accumulating MSCI World ETF — like the iShares Core MSCI World UCITS (EUNL) — available to most EU residents. Over the past decade, it delivered an annualized 9.4% in EUR terms. Even in a sluggish 2022, it outperformed most 3a funds by 400–600 basis points.
Now factor in flexibility. Need to move to the UK for a job? No paperwork hell. Want to buy a house or start a business? Your ETF portfolio is liquid in days. Want to optimize your tax position each year? You’re in control, not boxed in by locked products or capricious government reforms.
If you’d invested EUR 7,000 per year in a global ETF (9% average return) from 2013 to 2023, you’d have EUR 110,000. In a typical Pillar 3a fund: just EUR 82,000. That’s a EUR 28,000 difference — and the ETF is fully yours.
And don’t give me the “but taxes!” refrain. Yes, you’ll pay some capital gains and maybe dividends tax, but most countries (Germany, Netherlands, Portugal) have allowances and flat rates (26.375% in DE, capped at EUR 1,000 exemption per year). That’s a small price for freedom and long-term growth. For the full tax picture, see The Best Tax-Efficient Investing Strategies for Europeans in 2026.
The Case Against Ditching Pillar 3a Entirely
To be fair, there are situations where Pillar 3a (or Riester, or Dutch third-pillar pensions) still makes sense. If you’re highly paid and expect to stay put, the upfront tax savings can compound — especially if your country lets you withdraw at lower rates upon emigration or retirement. And the forced discipline? For some, it’s a feature, not a bug.
What about market risk? In 2022, global equities sank 18%. Conservative 3a products with a hefty bond allocation lost just 4–5%. Some risk-averse savers value that stability, even if it means lower returns long term. And yes, the “pension gap” in aging Europe means state pensions alone won’t cut it — so any savings are better than none.
But let’s not kid ourselves. Most expats are not planning to retire in Switzerland. And bureaucratic withdrawal penalties or forced annuitization (hello, Dutch expats) can erase much of the original tax break.
ETF Investing: Not Just Hype, But the New Standard for Expats
Look at the facts: Europe’s ETF market hit EUR 1.8 trillion in 2025, and cross-border investing keeps getting easier and cheaper. Platforms like DEGIRO, Trade Republic, and Scalable Capital have slashed fees below 0.3% per year. The days of high-minimum, high-fee, home-biased Pillar 3a “funds” are coming to an end.
Want proof? The number of Swiss expats withdrawing Pillar 3a upon leaving the country jumped 42% from 2019 to 2024, according to the Swiss Federal Tax Administration. Why? Because they want control, not handcuffs.
For those who crave efficiency, flexibility, and growth, ETFs are not just “the new thing” — they’re the rational default. Yes, keep your eyes on accumulating vs. distributing ETF tax impacts (read our deep-dive). But make no mistake: ETFs are the future for internationally mobile professionals.
The Verdict: Blend, Don’t Blindly Max Out
Here’s my take: Pillar 3a is no longer the slam-dunk it once was for European expats. The tax break is nice, but the illiquidity, mediocre returns, and bureaucratic nightmares on exit are not. For most mobile professionals, the optimal move in 2026 is to contribute the minimum needed to capture the bulk of the tax deduction (or skip it entirely if you’re already planning a move), then pour the rest into a globally diversified ETF portfolio.
Don’t let nostalgia for “safe” pension products sabotage your financial freedom. The numbers don’t lie — ETFs outgrow, outsmart, and outflex Pillar 3a for the next generation of European expats.
Prediction: By 2030, Europe’s expat class will treat legacy pension pots as a tax tool, not a main vehicle. The real wealth will be built in liquid, borderless funds — not locked boxes. The sooner you act, the further ahead you’ll be.
