Of the 9 stock brokers & investing apps on this list, 5 serve Spain from a CySEC licence in Cyprus (eToro, Trading 212, NAGA and 2 more), 1 serves Spain from a CBI licence in Ireland (Interactive Brokers), 1 serves Spain from a KNF licence in Poland (XTB) and 1 serves Spain from a Finantsinspektsioon licence in Estonia (Lightyear); 1 more is licensed by BaFin.

Currency conversion, which you pay on every US share bought from a non-dollar account, costs from 0.25% (DEGIRO) to 0.5% (XTB). DEGIRO charges €2 per order for US stocks.

• Search the company name on the CNMV register (cnmv.es); for a firm licensed elsewhere, on its home regulator's register too (CySEC, CBI and KNF for most of this list).
• Check which company your contract is with. Interactive Brokers, for example, onboards residents of Spain through Interactive Brokers Ireland Limited (CBI licence C423427), and the name on the account-opening documents should match the list.

Yes, with a licensed provider. Brokers need MiFID II authorisation from an EEA regulator; firms authorised elsewhere in the EEA may serve residents under the European passport.

By Coinish Score, Interactive Brokers (71/100, Editor Rating 4.1/5), through Interactive Brokers Ireland Limited (CBI licence C423427). eToro (71) and XTB (69) follow. The score rates the company that would serve you in Spain, so the same brand can rank differently in another country.

None of the 9 brokers here is a Spanish firm. Each serves Spain under a licence from another EU country.

The Agencia Tributaria's Modelo 720 information return has a separate block for securities held or managed abroad. You have to file once that block is worth more than €50,000, so a sizeable portfolio at a foreign broker can trigger it. After that, you only file again when the value has gone up by more than €20,000 since your last return.

Yes. A firm authorised under MiFID II in one EEA country can serve residents of the others once its home regulator has notified them. All 9 on this list reach Spain that way, most from Cyprus (5), Ireland (1) and Poland (1).

The home regulator supervises the firm and its compensation scheme applies, while CNMV can still set conduct rules for clients in Spain.

If a broker fails, the compensation scheme of the regulator that licenses it applies, not one chosen by where you live. For this list: Investor Compensation Fund (Cyprus): 90% of covered claims, up to €20,000 for clients of CySEC-licensed investment firms (5 on this list); Investor Compensation Company (ICCL): 90% of the loss, up to €20,000 per investor for clients of CBI-licensed investment firms (1 on this list); KDPW investor compensation scheme (Poland): 100% up to €3,000 and 90% above that, at most €20,100 per investor for clients of KNF-licensed investment firms (1 on this list); Entschädigungseinrichtung der Wertpapierhandelsunternehmen (EdW): 90% of the claim, up to €20,000 per investor for clients of BaFin-licensed investment firms (1 on this list). Compensation covers missing client money and assets after a firm's failure, never trading losses.

Gains on shares traded on official markets are savings income and go in section F2 of the IRPF return, however long you held them. For 2025 the state and regional scales on savings income each run from 9.5% on the first €6,000 to 15% above €300,000, so the combined rate is 19% to 30%. A net loss on sales can be offset against dividends and interest, but only up to 25% of their positive balance for the same year. Anything left over carries forward for four years.
