Businesses and self-employed individuals operating in the Comunitat Valenciana must pay close attention to an agreement that may alter the fiscal and administrative rules applicable to them. On 23 February 2026, the Comisión Bilateral de Cooperación between the Administración General del Estado and the Generalitat Valenciana reached an agreement in relation to Ley 5/2025, of 30 May, on fiscal measures, administrative and financial management, and organisation of the Generalitat. This agreement was published by means of a Resolution of 27 February 2026 of the Secretaría General de Coordinación Territorial and appeared in the BOE on 25 March 2026.
The mechanism is significant: when the State identifies possible jurisdictional or constitutional conflicts in a regional regulation, it has two options. The first is to challenge it directly before the Tribunal Constitucional. The second, which is the route activated here, is the negotiated path through the Comisión Bilateral. This second route is more agile and can produce specific regulatory changes without the need for judicial proceedings.
What does this regulation establish?
The published agreement formalises the outcome of the negotiation between the State and the Generalitat Valenciana on Ley 5/2025. This regional law governs three main areas:
- Fiscal measures: changes to own or transferred taxes managed by the Generalitat Valenciana.
- Administrative and financial management: modifications to procedures, organisation and management of regional public resources.
- Organisation of the Generalitat: structural changes to the Valencian regional administration.
The bilateral agreement may have two specific effects on this law:
- Commitments to amend: the Generalitat commits to modifying certain provisions that the State considers to encroach on state competences or violate the Constitution.
- Agreed interpretations: both administrations agree on how certain articles should be interpreted and applied, without the need to amend the legal text.
At the time of publication of this analysis, the specific provisions affected by the agreement have not been detailed in the resolution published in the BOE. It is necessary to monitor regulatory developments to determine which specific aspects are modified or conditioned.
Economic and operational impact
The direct impact on Valencian businesses and self-employed individuals depends on which specific provisions of Ley 5/2025 are ultimately modified or reinterpreted. However, there are immediate operational consequences that must be taken into account:
- Temporary regulatory uncertainty: until the affected provisions are known, there is uncertainty regarding the definitive application of certain fiscal and administrative measures under Ley 5/2025.
- Possible changes to fiscal obligations: if the agreement entails modifying provisions of a fiscal nature, the tax obligations of Valencian businesses and self-employed individuals could differ from what was initially set out in the law.
- Impact on administrative procedures: changes to administrative and financial management may affect deadlines, requirements and procedures that businesses must comply with before the Valencian regional administration.
- Risk of incorrect application: applying provisions that are subsequently amended as a result of the agreement may create situations of legal uncertainty for businesses.
Who is affected?
This agreement and Ley 5/2025 affect all economic operators subject to the fiscal and administrative regulations of the Comunitat Valenciana:
- Businesses with a registered tax address or activity in the Comunitat Valenciana.
- Self-employed individuals who pay taxes or carry out their activity in the Comunitat Valenciana.
- Business groups with subsidiaries or establishments in the Comunitat Valenciana.
- Businesses carrying out transactions subject to own or transferred taxes managed by the Generalitat Valenciana.
- Entities that interact with the Valencian regional administration in administrative or financial procedures.
- Tax and legal advisors managing obligations for clients with activity in the Comunitat Valenciana.
- CFOs and financial directors of companies with a presence in the Comunitat Valenciana who must plan their regional tax obligations.
Practical example
An industrial company headquartered in Valencia that has been applying since June 2025 the fiscal measures introduced by Ley 5/2025 — for example, regarding regional deductions or applicable rates on transferred taxes — now finds itself in a situation of uncertainty.
If the bilateral agreement means that the Generalitat must amend any of those fiscal provisions, the company may have been applying regulations that are going to change. This could require it to review its tax returns, adjust its tax provisions or modify its internal compliance procedures.
The recommended immediate action for this company is to identify which specific articles of Ley 5/2025 apply to its daily operations and to actively monitor the amendments resulting from the bilateral agreement, in order to adapt its tax position as soon as the definitive changes are known.
What should businesses do now?
- Identify which provisions of Ley 5/2025 apply to your activity: review with your tax advisor which fiscal, administrative or financial measures under Ley 5/2025 directly affect your business or activity in the Comunitat Valenciana.
- Activate regulatory monitoring: establish an alert system to be informed as soon as the specific amendments resulting from the bilateral agreement between the State and the Generalitat Valenciana are published.
- Assess the risk of provisional application: if you are applying measures under Ley 5/2025 that could be affected by the agreement, consult your legal advisor on whether it is prudent to maintain that application or adopt a more cautious position.
- Review tax provisions: if the uncertainty affects tax obligations already accounted for, consider whether it is necessary to adjust tax provisions in your financial statements.
- Consult the official source: access the Resolution published in the BOE and the full text of Ley 5/2025 to gain a complete picture of the measures at stake.
