CLM Administrative Simplification Law 2026: what changes for companies and procedures

Key data

Companies operating in Castilla-La Mancha can now apply with full legal certainty the new procedures of the Law 4/2025 on Simplification, Streamlining and Administrative Digitalization. The bilateral agreement between the State and the Autonomous Community, reached on March 25, 2026 and published on April 21, closes the jurisdictional conflict without need for appeal to the Constitutional Court.

This has a direct consequence for any company that processes licenses, authorizations, prior communications or any procedure before the Castilla-La Mancha regional administration: the law that simplifies those procedures is final and applicable.

What does this regulation establish?

The Bilateral Commission for Cooperation General State Administration — Autonomous Community of Castilla-La Mancha is the institutional mechanism activated when the State detects possible jurisdictional conflicts in a regional law. In this case, the conflict originated in Law 4/2025, of July 11, which regulates the simplification, streamlining and digitalization of administrative procedures in Castilla-La Mancha.

The result of the bilateral process is as follows:

• Both administrations have negotiated and resolved the discrepancies in an extrajudicial manner.
• No appeal has been filed with the Constitutional Court.
• Law 4/2025 remains in force, with the modifications or interpretations that may have been agreed in the agreement.
• The application of the regional simplification regulation is guaranteed with full legal certainty.

The agreement was adopted on March 25, 2026 and published by Resolution of the General Secretariat of Territorial Coordination on March 30, 2026, with publication in the BOE on April 21, 2026.

Law 4/2025 affects the following areas of the relationship between citizens, companies and the regional administration:

• Administrative procedures before bodies of the Junta de Castilla-La Mancha.
• Resolution deadlines for procedures.
• Digital procedures and electronic processing.
• Reduction of bureaucratic burdens for companies and citizens.

Economic and operational impact

For companies with activity in Castilla-La Mancha, the impact of this agreement is mainly legal certainty and reduction of operational uncertainty. While the jurisdictional conflict was open, there was a risk that part of Law 4/2025 would be challenged or suspended as a precautionary measure, which would have generated uncertainty about which simplified procedures were applicable.

With the agreement closed, companies can:

• Plan their administrative procedures on a stable regulatory basis.
• Take advantage of the reduced deadlines and digital procedures established by Law 4/2025 without risk of them being reversed through judicial channels.
• Reduce management costs associated with administrative bureaucracy in the region.

The digitalization and simplification of administrative procedures has a real economic impact for companies: less time spent on procedures, lower costs for management and advisory services for routine procedures, and greater agility in obtaining licenses and authorizations necessary to operate.

Who does it affect?

This agreement and Law 4/2025 that it confirms directly affect:

• Companies with headquarters or activity in Castilla-La Mancha that carry out procedures before the regional administration: activity licenses, sectoral authorizations, prior communications, subsidies, public contracts.
• SMEs and self-employed workers that depend on agile administrative procedures to start or maintain their activity in the region.
• Advisory and management firms that process files before bodies of the Junta de Castilla-La Mancha on behalf of their clients.
• Local administrations in the region, which are also affected by the regional simplification regulation.
• Citizens of Castilla-La Mancha who carry out any procedure before the regional administration.

Practical example

An industrial sector company with a plant in Albacete needs to renew an environmental authorization before the Junta de Castilla-La Mancha. Under Law 4/2025, this procedure has been simplified: processing is digital, resolution deadlines have been reduced and redundant documentary requirements have been eliminated.

Before the bilateral agreement, the compliance officer of that company had a legitimate doubt: can I already apply the simplified procedure or is there a risk that the Constitutional Court will suspend it? With the agreement of March 25, 2026, that doubt disappears. The company can process the renewal through the simplified digital procedure established by Law 4/2025 with full assurance that this regulatory framework is final and will not be reversed.

The same reasoning applies to any company that manages opening licenses, prior communications of start of activity, applications for regional subsidies or any other procedure before the Castilla-La Mancha administration.

What should companies do now?

1. Confirm what procedures you have pending before the Junta de Castilla-La Mancha and verify if Law 4/2025 has modified the applicable procedure (deadlines, documentation, submission channel).
2. Update internal administrative processing procedures to take advantage of the digital channels and reduced deadlines established by Law 4/2025, now with full legal certainty.
3. Inform operations and compliance teams that the regulatory framework for regional simplification in Castilla-La Mancha is stable and applicable without reservations.
4. Consult with your advisory or management firm if there are specific procedures that have been modified by Law 4/2025 and that are still being processed through the old method, to adapt the file to the new framework.
5. Review updated resolution deadlines to correctly plan the times for obtaining licenses, authorizations or administrative resolutions in the region.
