Best Broker for Expats in Spain (2026): What to Look For

Moving to Spain, or already settled there, changes how you invest. As an English-speaking expat you face questions a local investor rarely thinks about: will a broker accept you as a Spanish resident, can you keep the account if you move on again, and what does it cost when your money crosses currencies? This guide covers what matters when you invest from Spain, and which brokers tend to handle it best. It is about choosing a broker, not tax advice: Spain has its own rules, so confirm your own position with a local adviser.

For the wider picture, start with investing in Europe as an expat and how to start investing in Spain.

What matters when you invest from Spain

• Acceptance for Spanish residents. Confirm the broker actually onboards residents of Spain. Not all do, and some restrict certain nationalities.
• Account portability. Expats move. The real question is whether you can keep the account and simply update your residence if you leave Spain, or whether you would have to close it and start again somewhere new.
• Low FX and multi-currency. If you earn or hold money in pounds or dollars but invest in euro, currency-conversion costs add up fast. A broker with genuinely low FX or proper multi-currency accounts saves real money.
• UCITS (non-US) fund access. As a non-US investor in Europe you generally want UCITS ETFs, not US-domiciled funds, for tax and estate reasons. See UCITS ETFs explained, and check your broker offers them.
• Clear protection. Know which entity holds your account and what investor protection applies. It matters more in cross-border setups.

A note on Spanish tax and reporting

This is a broker guide, not tax advice, but two things are worth flagging so you get the right help. Spain taxes investment income under its own savings-income rules, and Spanish residents have historically had to declare overseas assets (the Modelo 720 declaration), where the rules and penalties have changed in recent years. Both are reasons to speak to a local gestor or tax adviser about your own situation rather than rely on a general guide. Choose the broker on the points above, and get the tax structure right separately.

Which brokers tend to handle it best

A starting point, not a verdict. Confirm current terms and acceptance for your situation.

• Interactive Brokers is the usual answer for expats in Spain, and for good reason: it accepts residents across many countries including Spain, offers the widest global market access and UCITS ETFs, has among the lowest currency-conversion costs anywhere, and lets you keep the account and update your residence if you move on. The platform is more complex, but that flexibility suits a mobile life.
• Trade Republic and Trading 212 are strong, low-cost options if you are settled in Spain and investing in euro: free or commission-free, simple, and good for regular ETF investing. The trade-off is that they are more euro- and single-country focused, so residency restrictions can matter more if you relocate often. See their fee breakdowns for Trade Republic and Trading 212.

A note for US citizens

If you are a US citizen or green-card holder living in Spain, you face a separate, stricter set of rules (FATCA reporting, and the PFIC treatment of non-US funds), and many European brokers will not accept you at all. That is a specialist situation that deserves dedicated professional advice, not a general guide like this one.

The bottom line

For most English-speaking expats in Spain the priorities are the same: a broker that will accept you, keeps your account portable, keeps FX low and offers UCITS funds. That points many toward Interactive Brokers, with Trade Republic or Trading 212 as simpler euro options if you are settled.
