Foreign Companies & Cross-Border Business

Can a Spanish tax resident own a company registered in another country?​

Yes. A person who is tax resident in Spain can generally own a company incorporated in another country. However, ownership of a foreign company does not automatically remove Spanish tax, reporting, or social security obligations.

The company's obligations, the owner's personal tax obligations, and social security requirements must each be evaluated separately. Many expats, digital nomads, and international business owners legally own companies outside Spain while residing in Spain.

Notes​

Owning a foreign company and being tax resident in Spain are not mutually exclusive. Many expats, digital nomads, and international business owners legally own companies outside Spain while residing in Spain.

If I own a foreign company while living in Spain, do I only pay taxes where the company is registered?​

Not necessarily. A Spanish tax resident is generally taxed in Spain on worldwide income. Depending on how money is received from the company (salary, dividends, director compensation, distributions, etc.), income may be reportable and taxable in Spain even if the company is incorporated abroad.

Tax treaties may help prevent double taxation, but do not necessarily eliminate Spanish tax obligations. The outcome depends heavily on how funds are withdrawn, the type of company involved, and the applicable tax treaty. A U.S. LLC, UK Ltd, Estonian OÜ, and German GmbH may not be treated identically under Spanish tax rules.

Does an A1 certificate eliminate Spanish tax obligations?​

No. An A1 certificate primarily determines which country's social security system applies under EU coordination rules. It is not an income tax document and does not determine where income taxes are due.

A person may still have Spanish tax obligations even if covered by another country's social security system through an A1 certificate. The A1 certificate addresses social security coverage only; income tax obligations are determined separately under national tax laws and applicable tax treaties.

Community discussions often confuse tax treaties and A1 certificates. The A1 certificate addresses social security coverage only; income tax obligations are determined separately under national tax laws and applicable tax treaties.
