How to buy US stocks from Europe: brokers, W-8BEN and withholding tax

Key takeaways

• Most European brokers offer US shares on NYSE and Nasdaq.
• Currency conversion fees can cost more than commissions.
• A valid W-8BEN cuts US dividend withholding from 30% to the treaty rate, often 15%.
• Non-residents generally pay no US tax on capital gains.
• UCITS ETFs are a common alternative to US-listed funds.

Buying shares of US companies such as Apple or Nvidia from Europe is straightforward with most online brokers. The parts that trip people up are currency costs, the W-8BEN form and US withholding tax on dividends.

Step 1: Choose a broker with US market access

Most European online brokers and many banks offer US stocks listed on the NYSE and Nasdaq. Compare:

• Trading fees per order on US markets.
• Currency conversion fees. Your euros must be converted to dollars; fees are often a percentage of the amount and can exceed the trading commission.
• Account type. Some countries have tax-advantaged accounts (for example the Finnish equity savings account, osakesäästötili) with different rules for foreign dividends.
• Regulation and investor protection in the broker’s home country. See broker.

Step 2: Sign the W-8BEN form

The W-8BEN is a US tax form in which a non-US person certifies their foreign status and claims tax treaty benefits. Brokers usually ask you to sign it electronically when you open an account or first buy US shares. It is generally valid until the end of the third calendar year after you sign it, after which you must renew.

Without a valid W-8BEN, US dividends are generally withheld at the full 30% rate.

Step 3: Understand dividend withholding tax

The US withholds tax on dividends paid to foreign investors. The standard rate is 30%, but tax treaties reduce it for residents of many countries. For residents of most EU countries, including Finland, the treaty rate on portfolio dividends is 15% with a valid W-8BEN.

In many countries you can credit the US tax against your domestic tax on the same dividend, so you are not taxed twice in full. How this works depends on your country and account type; in some tax-advantaged accounts the foreign tax cannot be credited. Check your tax authority.

US capital gains are generally not taxed by the US for non-resident individuals; you pay tax on them in your country of residence.

Step 4: Place the order

US regular trading hours are 9:30–16:00 New York time, which is usually 16:30–23:00 in Finland (the gap shifts briefly when the US and EU change clocks on different dates). Many brokers also offer pre-market and after-hours trading with wider spreads. Use a limit order if you want price control. Fractional shares are offered by some brokers.

Currency risk

Your investment is in US dollars. If the dollar weakens against the euro, your euro return falls even if the share price stays the same, and vice versa.

Alternative: UCITS ETFs

Instead of single stocks, many Europeans buy US exposure through EU-domiciled (UCITS) ETFs tracking the S&P 500 or Nasdaq-100. US-domiciled ETFs are often unavailable to EU retail investors because they lack the required key information documents. Irish-domiciled funds generally benefit from a 15% US withholding rate at fund level. See S&P 500 vs Nasdaq-100 and accumulating vs distributing ETFs.

Common mistakes to avoid

• Ignoring currency conversion fees.
• Letting the W-8BEN expire.
• Assuming foreign dividend tax is always creditable in a tax-advantaged account.
• Using market orders in thin extended-hours trading.

Bottom line

To buy US stocks from Europe, pick a broker with low currency fees, sign the W-8BEN to get the reduced treaty withholding rate, and understand how foreign dividend tax is credited where you live. Track the companies on Hodlia’s stock pages and read what is a stock for the basics.
