Cadastre-FETAP Agreement 2026: What Changes for Tax Advisors

Key data

Tax advisors and tax technicians integrated in FETAP can continue operating normally with the Cadastre. The General Directorate of the Cadastre has published the amendment that modifies and extends the collaboration agreement signed with the Spanish Federation of Professional Associations of Tax Technicians and Tax Advisors (FETAP), through the Resolution of May 6, 2026 (BOE-A-2026-10405).

The extension prevents a gap in the collaboration framework, which would have forced professionals to manage their clients' cadastral procedures through ordinary channels, which are slower and have fewer available tools.

What does this regulation establish?

The amendment has two specific effects on the previous agreement between the Cadastre and FETAP:

• Modification: Introduces changes to the conditions of the original agreement. Although the exact details of the modifications are not specified in the published resolution, this type of amendment typically updates technical procedures, access systems or conditions for using cadastral information.
• Extension: Extends the validity of the agreement, ensuring that professionals associated with FETAP do not lose access to the cadastral services and information they had agreed upon.

The original agreement facilitates tax advisors and tax technicians from FETAP to act on behalf of their clients before the Cadastre, accessing:

• Cadastral data queries
• Cadastral certifications
• Information necessary for real estate, tax and patrimonial operations

Without this agreement, each procedure would require express authorization from the owner or access through general channels, which significantly slows down the daily operations of any advisory firm.

Economic and operational impact

The impact of this regulation is not economic in terms of direct costs or new fees: no new payments or penalties are introduced. The impact is fundamentally operational.

For tax and tax advisory firms integrated in FETAP, the continuity of the agreement means:

• No interruptions in operations: Workflows for obtaining cadastral data from clients are not altered. There is no need to adapt processes or seek alternative channels.
• Maintenance of access tools: The credentials, platforms and procedures agreed with the Cadastre remain in force under the same conditions.
• Agility in real estate and patrimonial operations: Cadastral queries, certifications and verifications for sales, inheritances, asset declarations or tax appeals can continue to be processed with the same speed.

If the agreement had expired without extension, advisory firms would have had to manage each cadastral access individually, with the resulting increase in time and administrative cost per operation.

Who does it affect?

This regulation directly affects:

• Tax advisors integrated in FETAP who manage cadastral procedures on behalf of individual or legal entity clients.
• Tax technicians associated with FETAP who work with cadastral data for tax settlements, appeals or declarations.
• Advisory firms and companies whose professionals are federated in one of the associations integrated in FETAP.

Tax or tax advisors not associated with FETAP are not affected by this regulation: they neither lose nor gain cadastral access with this resolution.

It also does not directly affect end clients (companies, individuals), although they do benefit indirectly from their advisor being able to continue managing their cadastral procedures with agility.

Practical example

A tax advisory firm associated with an entity integrated in FETAP regularly manages the following operations for its clients:

• Obtaining cadastral certifications for real estate sales operations.
• Consultation of cadastral values to calculate the Tax on the Increase in Value of Urban Land (municipal capital gains tax).
• Verification of cadastral data in Wealth Tax declarations or in inheritance proceedings.

Thanks to the extension of the agreement, the firm can continue accessing the cadastral platform directly with its collaborator credentials, without needing to request express authorization from the client for each query or to process access through the Cadastre's general electronic office.

If the agreement had expired without renewal, the same firm would have had to manage each access individually, adding administrative steps to each operation and extending response times to the client.

What should advisors do now?

1. Verify association with FETAP: Confirm that the firm or professionals are actually integrated in one of the member associations of FETAP, as the agreement only applies to federated members.
2. Review the full text of the amendment: Consult the resolution in the BOE (BOE-A-2026-10405) to identify whether the modifications introduced affect any procedure, credential or access condition that requires internal updating.
3. Check that access continues to work: Verify that the tools and credentials for accessing the Cadastre work correctly under the new conditions of the amendment.
4. Communicate to internal teams: Inform professionals in the firm who manage cadastral procedures that the agreement remains in force and of any operational changes resulting from the modification.
5. Contact FETAP if you have doubts: If there are doubts about the scope of the modifications or the new conditions of the agreement, the most direct way is to consult with the federation itself, which will have received detailed information from the Cadastre.
