Will the EU force Spain to withdraw Real Decreto 933/2021?

No, the European Commission will not force Spain to withdraw Real Decreto 933/2021 in 2027, and you should absolutely not stop filing until then. Your obligations to register guests remain fully in force.

The European Commission has indeed opened an infringement procedure against Spain concerning its traveller-data regime, specifically case INFR(2026)4005. This procedure, initiated on 4 June 2026, raises concerns about the amount of data collected, the accessibility of this data by the police, and the three-year retention period. However, an infringement procedure is a legal process that can take several years and does not automatically lead to the withdrawal or cancellation of a national law.

Crucially, the opening of this procedure has not cancelled anything, and nothing about your legal obligations has changed. You are still required to report guest details to SES.Hospedajes within the established deadlines (Real Decreto 933/2021, article 6.3). Failing to do so can lead to significant fines, ranging from €601 to €30,000 for not filing at all (Ley Orgánica 4/2015, de 30 de marzo, de protección de la seguridad ciudadana, article 39.1.b).

Until the Spanish government officially amends or withdraws Real Decreto 933/2021, or a court rules it invalid, you must continue to comply with all guest registration requirements. Acting on the assumption that the law will be withdrawn would expose you to legal penalties.
