TGSS-INE Agreement Extension 2026: What Changes in Your Social Security Procedures

Key data

The General Treasury of Social Security and the National Institute of Statistics have extended their municipal registry data sharing agreement, published in the Official Gazette on May 11, 2026 through the Resolution BOE-A-2026-10197. The agreement allows Social Security to directly consult the municipal registry to verify residence and address data without requiring the citizen or company to provide additional documentation in each procedure.

The extension does not introduce substantive changes to how the system works: its objective is to prevent an interruption in the data flow between both bodies, ensuring that ongoing administrative procedures are not affected.

What does this regulation establish?

The original agreement between the TGSS and the INE establishes a municipal registry data sharing channel that allows Social Security to access citizens' residence and address information directly from the municipal registry, without needing to request it from the interested party in each transaction.

The published amendment extends this agreement on the same terms, ensuring the continuity of the following aspects:

• TGSS access to residence and address data from the municipal registry managed by the INE.
• Verification of the identity and location of Social Security system beneficiaries and contributors.
• Streamlining of procedures related to benefits, registrations and deregistrations in the system.
• Compliance with applicable data protection regulations in all municipal registry information transfers.

Data transfer is not unrestricted: it is limited to the specific administrative purposes of the agreement and subject to the guarantees established by applicable data protection regulations in Spain.

Economic and operational impact

This extension generates no direct costs for companies, self-employed workers or citizens. Its impact is fundamentally operational and translates into administrative efficiency:

• Less documentation to provide: Social Security can automatically verify the address of workers and beneficiaries, reducing the documentary burden in registration, deregistration and benefit procedures.
• Continuity without interruptions: Without this extension, the TGSS would have lost automated access to the registry, which would have slowed down case management and increased resolution times.
• Data protection guaranteed: The agreement requires that all information transfers comply with applicable data protection regulations, protecting workers and beneficiaries against unauthorized use of their residence information.

For HR departments and advisory firms managing worker registrations and deregistrations, the continuity of this automated access means that processes do not change and no internal procedures need to be adapted.

Who does it affect?

• Citizens with active Social Security procedures: Any person who applies for or receives benefits, or who is in the process of registration or deregistration in the system.
• Companies and self-employed workers with registered employees: Automatic verification of their workers' addresses remains unchanged.
• HR departments and management firms: Registration, deregistration and benefit management processes continue to function with the same level of automation.
• TGSS and INE bodies: They are the direct signatories of the agreement and responsible for its compliance.
• Benefit recipients: Pensioners, unemployment benefit recipients and other beneficiaries whose residence is verified periodically.

Practical example

A company with 15 employees registers a new employee with Social Security. In the process, the TGSS needs to verify that the address declared by the worker matches the one in the municipal registry.

Thanks to this extended agreement, the TGSS consults directly with the INE without the company or worker having to provide a registry certificate. The procedure is resolved automatically and without additional documentation.

Without this extension, the TGSS would have lost that direct access to the registry, which could have required the worker to provide an updated registry certificate to complete the registration, lengthening the process and adding administrative burden to both the company and the employee.

What should companies do now?

1. Do not modify any internal processes: The extension maintains the agreement on the same terms. Registration, deregistration and benefit management procedures do not change.
2. Inform workers if necessary: If your company communicates to employees how their data is managed, remember that Social Security can consult their residence data in the municipal registry under this agreement.
3. Review records of processing activities: If your company acts as a data controller and collaborates with Social Security in procedures involving address data, verify that your record of processing activities correctly reflects this transfer.
4. Consult with your advisory firm in case of doubts about data protection: The agreement requires compliance with data protection regulations. If you have doubts about how it affects your workers' data, consult with your data protection officer or legal advisor.
