On 27 June, Spain published Order HAC/649/2026 of 21 June in the Official State Gazette (BOE), amending the list of non-cooperative jurisdictions originally approved under Order HFP/115/2023.
Why has the list been updated?
This update reflects Spain’s commitment to keeping its tax framework aligned with the international standards established by the European Union and the OECD, reinforcing efforts to combat tax fraud and aggressive tax planning.
Key changes
The Order removes the following jurisdictions from the list, recognising the progress they have made in terms of tax transparency and fair taxation:
- Barbados
- Dominica
- Gibraltar
- Seychelles
- Trinidad and Tobago
In addition, Samoa’s offshore business regime is no longer considered a harmful tax regime.
New addition to the list
The Order also adds the International Holding Companies tax regime of the Russian Federation to the list of harmful tax regimes. This change will become effective six months after the publication of the Order.
What does this mean for businesses?
Being classified as a non-cooperative jurisdiction can have significant tax implications across a range of areas, including:
- the application of specific anti-abuse measures;
- restrictions on the deductibility of certain expenses and transactions;
- enhanced reporting and documentation requirements;
- implications for related-party transactions and international corporate structures.
Companies with investments, subsidiaries or transactions involving the affected jurisdictions should assess how these changes may impact their tax planning and compliance obligations.
Key takeaways
The regular review of this list highlights the importance of continuously monitoring international tax developments to ensure effective tax risk management.
Spain continues to align its tax framework with EU and OECD standards, meaning further updates to the tax system can be expected. Contact our international tax specialists to help ensure your business remains compliant and operates efficiently in Spain.
