Investing in the US vs. Europe: Accounts, Taxes and Market Access Compared
How a retail investor in the United States and one in Europe buy the same assets differently: 401(k) and IRA vs. European wrappers, capital gains tax, UCITS ETFs, PRIIPs and why Europeans can't just buy US ETFs.
An American and a German can both decide to invest $500 a month in the stock market — and then discover that almost everything about how they do it is different. This guide compares the two systems honestly: accounts, taxes, products and the hidden frictions.
Tax-Advantaged Accounts
United States. The system is built around employer plans and IRAs: - 401(k): contributions up to $23,500 (2025 limit, plus catch-up over age 50), pre-tax or Roth, often with an employer match — free money that should never be left on the table. - IRA / Roth IRA: $7,000 per year; Roth contributions grow tax-free forever. - Brokerage: unlimited, taxed annually.
Europe. There is no single European system; each country has its own wrapper: - UK: ISA (£20,000/year, completely tax-free) and SIPP pensions. - France: PEA (€150,000 cap, tax-free after 5 years) and assurance-vie. - Germany: famously no special stock wrapper — gains are taxed at the 26.375% flat Abgeltungsteuer, though the pension reform debate continues. - Netherlands: no capital gains tax at all; instead a deemed-return wealth tax (box 3) on total assets.
The UCITS Wall
The single biggest practical difference: since 2018, the EU's PRIIPs regulation requires funds sold to European retail investors to publish a Key Information Document. US-domiciled ETFs (VOO, QQQ, SPY) do not produce one, so European brokers cannot sell them to retail clients. Europeans instead buy UCITS ETFs — Irish- or Luxembourg-domiciled equivalents like CSPX (S&P 500) or VWCE (all-world) — which are often accumulating (dividends reinvested automatically) and enjoy a favorable US-Ireland treaty withholding rate of 15% on US dividends.
Americans face the mirror image: buying European funds triggers the IRS's punitive PFIC rules, so US investors stay in US-domiciled products.
Capital Gains Tax Snapshot
- US: 0/15/20% long-term federal rates by income, plus 3.8% net investment income tax above thresholds, plus state tax (0% in Texas/Florida, up to 13.3% in California).
- Europe: 0% in Belgium and (for gains) Switzerland; 19-28% in Spain's sliding scale; 26% in Italy; 30% in France's flat tax; 26.375% in Germany. Several countries (UK, Ireland) have annual exemptions.
Market Structure
US markets are deeper: the NYSE and Nasdaq together are larger than all European exchanges combined. Settlement is T+1 in the US (since May 2024) while the EU moved to T+1 in October 2027 planning with T+2 still standard. Commission-free trading is normal in both, though European neobrokers (Trade Republic, DEGIRO, Scalable) monetize via payment-for-order-flow arrangements the EU has decided to phase out by 2026.
Practical Takeaways
- Americans: max the employer match first, then Roth IRA, then taxable.
- Europeans: choose accumulating UCITS ETFs if your country taxes dividends annually.
- Both: currency matters. A European buying the S&P 500 is long USD; a 10% euro rally can erase a year of equity gains. Track EUR/USD on USD Euro 360 before large conversions.
