International tax, legal and employment
International taxation:
the keys to not overpaying
When your company, your investments or your employees cross borders, questions arise that a local advisor doesn’t cover: in which country each tax is paid, how to avoid double taxation and what has to be reported. These are the points we work on most.
Double taxation and residence
Spain has double taxation treaties with around a hundred countries. We analyse your tax residence (more than 183 days or centre of interests), where each type of income is taxed and how to apply the treaty or the tax credit, including non-residents who pay non-resident income tax (IRNR).
Beckham Law and work abroad
If you move to Spain, the impatriate regime lets you pay 24% up to €600,000 for six years. And if your employees work temporarily abroad, the exemption in article 7p of the Spanish income tax law can make up to €60,100 a year tax-free.
Structures and related-party transactions
We help you decide whether to open a subsidiary, a branch or work with agents in another country, and to document intra-group transactions at market value (related-party transactions and form 232) to avoid adjustments by the Tax Agency.
Expats and assets abroad
We manage the hiring of international employees and their social security under bilateral agreements, and reporting obligations such as form 720 for assets abroad or form 721 for crypto held outside Spain.
More information on the Spanish Tax Agency website and on the Ministry of Finance website, which publishes the double taxation treaties in force. Figures based on the rules in force in 2026; before you decide, we review your specific case.

Yes. We advise Spanish companies with activity abroad and companies and professionals from other countries who invest, work or settle in Spain. Everything is handled with digital documents, e-signature and video calls.
It depends on where you are tax resident (more than 183 days or your centre of economic interests) and on the double taxation treaty between both countries. We analyse your case so you don’t pay twice on the same income.
If you move to Spain and have not been resident in the previous five years, you can pay 24% up to €600,000 for six years. You must apply within six months of registering with social security, using form 149. We help you check whether you meet the requirements.
If you hold accounts, securities or property outside Spain worth more than €50,000 in each category, you must file form 720, and form 721 for crypto held abroad. We help you comply and check whether it needs updating each year.
You have a dedicated advisor you can call or write to, we remind you before every deadline and share your numbers in real time with Holded. That way your business stays up to date even with business in several countries, with no paperwork or waiting.
