He BOE (Official State Gazette) on May 25, 2026 publishes the reorganization of part of the internal structure of the State Tax Administration Agency (AEAT) so that taxpayer assistance is reinforced, better coordinating its service channels and ordering the management of transparency and management of tax data.
The reform that appears in the BOE changes the structure of the AEAT’s planning and institutional relations service and centralizes the planning of in-person, telephone and digital attention. The standard is within the Strategic Plan of the Tax Agency 2024-2027, which establishes as one of the main axes the development of a strategy and an effective model of institutional communication and taxpayer service.

As the official document points out, the importance of these tasks has led to redesigning the organization of the units in charge of this matter.
Treasury unifies personal, telephone and online assistance
One of the most relevant changes is the one that affects the way in which the Tax Agency organizes citizen service. The new structure attributes to the General Subdirectorate of Planning and Coordination of Information and Assistance the coordination of the common elements of information and assistance services, both electronic, telephone and in person.
This will allow the different taxpayer service channels to be unified under the same planning, so that citizens receive a homogeneous response regardless of whether they go to an office, call by phone or carry out their procedures through the Electronic Office or other channels.
The resolution also states that this subdirectorate will be in charge of preparing the proposal for the catalog of assistance services, integrating planning and establishing the indicators corresponding to the information and assistance services of all areas.
The Treasury may propose the approval of new technologies or taxpayer service channels as well as means of identification used in these services. The standard also attributes the function of guaranteeing the homogeneity of the technological tools used in information and assistance, in collaboration with the Tax IT Department and the functional departments.
New units for transparency
The reform also affects information management and transparency within the Tax Agency. Under the General Subdirectorate of External Communication, two specific units are created: the Information Transfer Unit and the Transparency, Right of Access and Reuse of information Unit.
The Information Transfer Unit will be in charge, among other functions, of analyzing and proposing the authorization of information transfers requested by other state agencies, supporting delegations in this matter, developing agreements and forms to articulate information exchanges and designing standardized supplies.
For its part, the Transparency, Right of Access and Reuse of Information Unit will coordinate all the actions of the Tax Agency related to regulations on transparency, access to public information, good governance and reuse of public sector information.
The territorial delegations of the AEAT change
The resolution incorporates the regulation of the Regional Institutional Relations Units, which will have their main headquarters in the special delegations of Andalusia, Catalonia, Comunitat Valenciana, Madrid, Navarra and the Basque Country.
These agencies will assume functions such as the management and monitoring of agreements with the Spanish Federation of Municipalities and Provinces (FEMP), autonomous communities and other public organizations; the processing of requests for unstructured information; coordination with associations, professional associations, notaries, registrars, chambers of commerce and business associations; and the centralization of relations with organizations such as the Labor Inspection or the General Treasury of Social Security regarding the transfer of information.
The standard also specifies the management, supervision and replacement regime of these regional agencies, which will be headed by a headquarters and may have deputy regional inspectors, coordinating inspectors, subgroup A1 officials or service heads.
