Understanding expat investing Europe guide is essential for making informed decisions in today’s market.

Let’s get something out of the way.

“If you’re an American living in Europe and you’ve been investing through a regular US brokerage account like it’s no big deal, you’re probably breaking rules you don’t even know exist.”

Not in a dramatic, jail-time way. More in a slow, expensive, paperwork-nightmare way that catches up with you during tax season.

This expat investing Europe guide exists because the real version of this conversation rarely gets told. Most articles you’ll find online are written by people who sell financial products or by expats who’ve been here for six months and think they’ve figured it out. They haven’t. I’ve watched people make mistakes that cost them tens of thousands of euros, not because they were greedy, but because nobody explained the system clearly.

Here’s what’s actually going on. When you move to Europe, your financial life splits into two overlapping worlds that don’t play well together. There’s the US tax system, which doesn’t care that you live in Amsterdam or Lisbon. It wants its cut no matter where your passport stamps land. Then there’s the local tax system in whatever European country you’ve moved to, which has its own rules about capital Gains, wealth taxes, and what counts as taxable income.

And then there’s the third layer that most expat guides skip entirely. The investment products themselves. The funds and ETFs you can actually buy as a US person living in Europe are dramatically different from what your friends back in the States can access. Some of what you’re used to is simply off-limits. Not because of your broker. Because of European regulations.

So let’s walk through this properly. Not the sanitized version. The real one.

Throughout this guide, we’ll explore expat investing Europe guide and how it directly impacts your financial future.

Why your US brokerage account stops working the way you expect – expat investing Europe guide

You’d think your Fidelity or Schwab account would just keep humming along after you move abroad. It doesn’t. The moment your address changes to a European country, most US brokerages Start restricting what you can do. Some will freeze your account entirely. Others will let you hold existing positions but block new purchases. A few will ask you to transfer out.

Why? Because of European securities regulations, specifically MiFID II. This is the regulatory framework that governs how investment products are sold within the European Union. Under MiFID II, US-registered funds and ETFs generally cannot be marketed or sold to investors located in the EU. Your brokerage isn’t being difficult. They’re complying with a legal requirement that carries serious penalties for violations.

This means that Vanguard’s US-listed ETFs, the ones with rock-bottom expense ratios and massive liquidity, become essentially unavailable to you as a resident of most European countries. You can usually hold what you already own. You typically can’t buy more.

Now here’s where it gets annoying. Some brokerages handle this better than others. Interactive Brokers has become the default recommendation in expat investing circles, and for good reason. They’re registered in multiple jurisdictions, they understand the cross-border situation, and they give you access to European exchanges where you can buy locally compliant funds. But they’re not perfect. Their interface looks like it was designed in 2004 and their customer service can feel like shouting into a canyon.

Schwab International accounts exist and work for many expats, but they’ve tightened restrictions over the years. Fidelity generally won’t open new accounts for US persons living in Europe. Vanguard US will ask you to transfer your assets elsewhere if you update your address to a European one.

The honest reality is that maintaining your old setup usually isn’t an option. You need to pick a new brokerage and that choice shapes everything else about your investing life in Europe.

The brokerage question nobody agrees on – expat investing Europe guide

There’s no single right answer here, but there are wrong ones. Let me walk through the main options with their actual trade-offs.

Interactive Brokers Ireland is the one most expats end up at. It gives you access to stocks, options, and UCITS-compliant ETFs across European exchanges. You can buy in euros, pounds, or dollars. The currency conversion costs are low, often under 0.20%, which matters more than people think when you’re funding an account from a European bank. The downside is the platform itself. It is powerful but unintuitive. If you’re used to the clean simplicity of Vanguard’s website, prepare for a steep learning curve.

Local brokerages are another option, and they vary wildly by country. In Germany, Scalable Capital and Trade Republic are popular. In France, Boursorama and Fortuneo. In the Netherlands, DEGIRO used to dominate before its acquisition byflatex. These platforms are cheap and user-friendly, but they may not accept US persons due to the compliance burden of SEC regulations. Some will. Many won’t. You need to check specifically.

Then there are the newer fintech options. Trading 212, eToro, and Revolut all advertise commission-free trading. They also tend to offer limited fund selections and may not support the specific investment strategy most long-term expats need. They’re fine for dabbling. They’re not where I’d build a retirement portfolio.

Here’s my honest take after watching hundreds of expats navigate this. Interactive Brokers is the most reliable default for US expats in Europe. It’s not the most pleasant experience. It is the one that will consistently let you do what you need to do without surprise lockouts or forced transfers.

“The biggest mistake I see expats make is choosing a brokerage based on the app design instead of the regulatory access. A beautiful interface means nothing if you can’t buy what you need to buy.”

US ETFs versus UCITS ETFs: the practical difference that changes your returns

This section is where most expat investing guides either oversell UCITS ETFs or pretend the difference doesn’t matter. Both are wrong.

When you can no longer buy US-listed ETFs, you turn to UCITS ETFs, which are the European equivalent. They’re regulated under Undertakings for Collective Investment in Transferable Securities rules. They trade on exchanges in Dublin, London, Frankfurt, and Paris. Many of them track the same indices as their US counterparts.

The iShares Core MSCI World ETF, traded under ticker EUN2 in Dublin and listed in euros, tracks the MSCI World Index just like its US-traded counterpart. The Vanguard FTSE All-World ETF trades as VWCE on the Xetra exchange in Germany. These are legitimate, well-constructed funds from reputable providers.

But there are real differences. UCITS ETFs tend to have slightly higher expense ratios. The difference is small, often 0.02% to 0.10% more than the US equivalent. Over decades, that adds up. On a €500,000 portfolio, an extra 0.10% in fees means €500 per year going to the fund provider instead of staying in your account.

The bigger issue is something called tracking difference versus tracking error. US ETFs, particularly Vanguard’s, have historically been excellent at matching their benchmark indices after fees. UCITS ETFs can have slightly wider tracking differences, partly because of the way they handle securities lending revenue and dividend withholding taxes within the fund structure.

Then there’s the currency factor. If you’re investing in euro-denominated UCITS ETFs but your long-term financial planning is in dollars, maybe because you plan to retire in the US or because you still file US taxes in dollars, you’re adding a currency conversion layer that affects your actual returns. This isn’t a reason to avoid UCITS ETFs. It’s a reason to think about it.

The counterintuitive truth is that for most expats, the UCITS switch is a non-issue in practice. The funds are cheap enough, the index coverage is broad enough, and the convenience of being able to invest regularly from a European bank account outweighs the marginal cost difference. People who spend hours trying to optimize between a 0.07% and a 0.20% expense ratio are often optimizing the wrong thing.

What matters more is your asset allocation and your savings rate. A broadly diversified UCITS ETF portfolio funded consistently will outperform a theoretically perfect US ETF portfolio that you can’t actually contribute to.

FAQ

Can I keep my US brokerage account after moving to Europe? – expat investing Europe guide

You can usually keep it open, but most US brokerages will restrict new purchases once your address is in Europe. You’ll typically be able to hold existing positions, sell them, and withdraw funds, but buying new US-listed securities may be blocked. Some brokerages will ask you to transfer out entirely. The specific restrictions vary by brokerage and change over time.

Are UCITS ETFs safe? – expat investing Europe guide

Yes. UCITS ETFs are regulated under European Union directives that impose strict requirements on fund diversification, leverage, and custody of assets. They’re among the most regulated retail investment products in the world. The fund providers, iShares, Vanguard, Amundi, and State Street Global Advisors, are large, established firms. The risk in a UCITS ETF is the market risk of the underlying index, not the safety of the fund structure itself.

Do I need to file taxes in both the US and my European country?

In most cases, yes. US citizens and green card holders must file US taxes on worldwide income regardless of residence. Your European country of residence will also tax your income and gains according to local rules. Tax treaties and foreign tax credits generally prevent true double taxation, but you’ll likely need to file in both jurisdictions. The complexity of your filings depends on your specific situation and the country you live in.

What is a PFIC and why should I care?

A Passive Foreign Investment Company is a US tax classification for foreign corporations that meet certain income or asset tests. Most non-US mutual funds, insurance-based investment products, and some structured notes qualify as PFICs. The tax treatment can be harsh, with potential effective rates well above normal capital gains rates and complex annual filing requirements on IRS Form 8621. UCITS ETFs generally do not qualify as PFICs, which is one reason they’re preferred by US expats.

Should I invest in my European country’s pension scheme?

It depends on the country and the specific product. Some European pension schemes are excellent for local residents but create PFIC complications for US expats. Others may be acceptable. The German Riester-Rente, for example, is generally not recommended for US expats due to PFIC issues. The French PER may be more manageable. Always check the specific fund composition before enrolling and consult a cross-border tax advisor.

How much do I need to start investing in Europe?

You can start with very little. Interactive Brokers has no minimum deposit for a cash account. Many UCITS ETFs can be purchased in single shares, so you could begin with as little as €50 to €100. The key is starting, not the amount. Regular contributions, even small ones, build the habit and benefit from compound growth over time.

What happens to my investments if I move to another European country?

Your brokerage account typically stays open regardless of which European country you live in, as long as the brokerage serves that country. Your tax situation, however, changes based on your new country of residence. Capital gains rates, wealth taxes, and available tax-advantaged accounts all vary. You may need to adjust your strategy when you move. The investments themselves don’t need to change just because your address does.
