June 2026 will mark an important milestone for multinational companies with subsidiaries in Spain, as it will be the first year in which they will have to submit the information forms derived from the Pillar 2 regulations: forms 240, 241 and 242 to the Tax Agency.
Below, we explain what this obligation entails and what the key deadlines are.
What is Pillar 2 and who is required to submit these declarations?
Pillar 2 is a set of international standards designed to ensure that multinational groups pay a minimum rate of corporate tax. In Spain, it is transposed through Law 7/2024, Royal Decree 252/2025, and Order HAC/1198/2025.
Every constituent entity located in Spain that forms part of a large multinational or national group must submit the Constituent Entity Communication declaring the Complementary Tax information return (Form 240). This communication includes:
- Identification of the entity and tax period
- Jurisdiction of the ultimate parent company or entity designated to file the declaration
- Details of the taxpayer substitute, if applicable
It should be noted that a single communication that includes all the information of the Spanish entities of the group is sufficient.
What other models should be submitted?
- Form 241: Supplementary Tax Information Return
This form collects information from all companies belonging to the multinational group. It is not required if the return is filed by a parent company in Spain or in a country with an information exchange agreement. - Form 242: Self-assessment of the Complementary Tax
This form must be submitted by Spanish entities when the effective tax rate of the group in Spain is lower than the minimum rate, for example, in the case of substitute taxpayers.
Deadlines for the first year (fiscal year 2024)
- Models 240 and 241: until June 30, 2026
- Model 242: until July 25, 2026
- Supplementary declaration (if applicable): until 25 July 2026
It is important to remember that, even if the safe harbor regime applies, in Spain there is still an obligation to submit the forms, even if no tax is owed.
In summary
The year 2026 will be crucial for multinational companies to comply with their Pillar 2 reporting obligations in Spain. The correct filing of forms 240, 241, and 242 ensures tax transparency and helps avoid penalties for non-compliance.
