Understand tax obligations
When you invest abroad you must meet reporting requirements both in Europe and, if you’re a US citizen or green-card holder, back in the States. Two of the most important US rules are FATCA and FBAR.
FATCA and Form 8938
The Foreign Account Tax Compliance Act, or FATCA, requires US taxpayers with significant foreign financial assets to file IRS Form 8938 alongside their annual tax return. As of 2025, you must report if your aggregate assets exceed:
- $200,000 at year-end, or $300,000 at any point in the year (married filing jointly)
- $100,000 at year-end, or $200,000 at any point in the year (single living abroad)
- Lower thresholds apply if you lived in the US part of the year [1]
Foreign financial assets include bank accounts, brokerage accounts, ETFs, mutual funds, certain crypto held on foreign platforms, and some insurance contracts. Missing this filing triggers penalties and potential tax understatements.
FBAR requirements
In addition to FATCA, US persons must file FinCEN Form 114, known as FBAR, if the combined maximum balance of all foreign bank accounts exceeds $10,000 at any time during the calendar year. Key points:
- FBAR is filed electronically with FinCEN by April 15, with an automatic six-month extension
- It covers bank, securities, brokerage, and certain crypto exchange accounts held outside the US [2]
Even if you fall below FATCA thresholds, you might still need to file an FBAR.
Penalties for noncompliance
Failing to file Form 8938 can cost you a base penalty of $10,000 plus $10,000 more for each 30-day period the form is late, up to $60,000, plus 20 percent of any underpaid tax due to undisclosed assets [2]. FBAR violations carry up to $10,000 per non-willful violation and up to $100,000 or 50 percent of the account balance per willful violation, with possible criminal charges. If you’ve missed filings you may qualify for streamlined compliance procedures aimed at nonresident taxpayers [1].
Navigate EU country rules
Europe does not have a single tax code. Each country sets its own residency criteria, reporting requirements, and withholding taxes on investment income.
Determine tax residency
You’re generally tax-resident in the country where you spend more than six months in a calendar year. Exceptions include posted workers and cross-border commuters.
| Scenario | Residency rule |
|---|---|
| Standard | More than 183 days in country |
| Posted worker | Covered by home system up to 24 months with PD A1 form |
| Cross-border commuter | Taxed where you work if you perform ≥25 percent of work there |
(European Commission [3])
Use double tax agreements
If two countries claim you as a resident, double tax treaties assign taxing rights to avoid double taxation. You may file for relief or credits in your home jurisdiction based on treaty provisions.
Meet host country reporting
Once you’re resident you must report worldwide income, including dividends, interest, and rental income from other countries. Some nations require annual declarations of foreign assets. Check local thresholds to avoid fines: for example Spain requires Form 720 for assets over €50,000 abroad.
Choose investment vehicles
Your choice of investment product affects your tax treatment, reporting burden, and risk profile.
Stocks and ETFs
Equity investments held in a European brokerage are subject to local withholding tax on dividends. You can often reclaim part of that withholding under US-EU treaties if you file Form W-8BEN with your broker. ETFs domiciled in Europe may classify as Passive Foreign Investment Companies (PFICs) under US law, triggering complex reporting and punitive tax rates unless you make a Qualified Electing Fund election.

Crypto assets
Crypto held on European platforms must be reported as foreign assets for FATCA/FBAR if your overall balance exceeds thresholds. Tax treatment varies: some countries treat crypto gains as capital gains, others as miscellaneous income. Track your cost basis carefully and report on local tax return schedules.
Real estate
Property investment can deliver rental yields and capital appreciation, but it involves:
- Annual property taxes based on assessed value
- Rental income reporting with allowable deductions (mortgage interest, maintenance)
- Capital gains tax on sale, often with taper relief for long-term holdings
- Inheritance tax on passing property to heirs [4]
Alternative options
Consider diversifying into:
- Gold and precious metals stored in vaults subject to local VAT [5]
- Crowdfunding and peer-to-peer lending platforms regulated by EU-wide rules [6]
- Private equity or angel rounds via local networks [7]
Select compliant accounts
Where you hold your assets matters for fees, controls, and compliance.
Local brokerage accounts
Opening a brokerage in your country of residence lets you pay domestic fees, access local platforms like iDEAL in the Netherlands, and build a credit history. EURES advisers recommend this for straightforward banking and investing [8].
US-based custodial accounts
If you maintain US investments you need a US address. Many banks and brokers won’t serve you without one. Some specialized firms enable you to keep US accounts from abroad, simplifying IRS reporting but often charging higher fees [9].
Cross-border fund options
International wealth managers partner with US and EU custodians to offer dual-compliant accounts. For example, Savile Capital Group works with a Wyoming-based bank to help US expats maintain US accounts while investing in Europe [9]. Explore expat investment accounts europe for more.
Manage cross-border planning
Beyond choosing products and accounts you need a holistic plan for currency, advice, and retirement.
Currency and repatriation
- Track exchange rates and use limit orders to optimize entry and exit points
- Beware conversion fees on non-euro transactions
- Repatriate dividends via tax-efficient structures or withholding reclaim processes
Work with qualified advisors
Cross-border investing and tax planning is complex. Look for advisers authorized in your host country and familiar with US rules if you’re a US citizen. Check credentials at europe expat financial planning and europe expat investment advisors.
Plan for retirement
If you receive US Social Security while abroad you must meet residency-verification requirements or make visits to the US to keep benefits [10]. For local pensions consider expat retirement investments europe and venue-specific products. Coordinate benefit timing to avoid gaps.
Mitigate regulatory risks
Proactive compliance keeps you out of trouble and preserves returns.
Understand PFIC rules
Foreign-domiciled funds can be PFICs, taxed unfavorably under US law. If you hold European ETFs or mutual funds, evaluate PFIC status and consider making a Qualified Electing Fund election or stick to US-domiciled vehicles when possible.
Consider post-Brexit impacts
British expats in the EU lost financial services passporting as of 2021. UK-based advisers can no longer manage EU clients without local authorization, potentially leaving portfolios unmanaged. Verify your adviser’s EU permissions to avoid service disruptions [11].
Review Social Security and benefits
If you’re covered by EU social security systems or remain on US Social Security, understand coordination rules, PD A1 forms for posted workers, and eligibility for health, pension, family, and unemployment benefits across borders [12].
Adopt best practices
Consistent habits reduce stress and keep you compliant.
Keep detailed records
Store statements, trade confirmations, exchange receipts, tax filings, and proof of physical presence if you need to maintain Social Security.
Seek professional support
An experienced cross-border tax advisor and wealth manager can guide you through changing rules. Explore europe expat wealth management europe to find qualified specialists.
Review investments regularly
Market conditions, tax thresholds, and reporting rules change. Schedule annual reviews to update your strategy, rebalance portfolios, and confirm compliance with both EU and US requirements.
