INE-Registrars Agreement 2026: what data is shared and how it affects your business

Key data

The data your company deposits in the Commercial Register—including annual accounts—is now an official source of national statistics. The INE and the College of Registrars of Property, Commercial and Personal Property of Spain have formalized an agreement, published in the BOE on October 10, 2026 (reference BOE-A-2026-21160), effective from October 1, 2026.

The agreement does not impose new reporting obligations on companies. Its logic is the opposite: instead of requesting more information from citizens and companies, the INE reuses existing administrative sources to reduce information burdens. But it has implications worth knowing about.

What does this regulation establish?

The agreement regulates the periodic supply of registry information to the INE and access to registry services, with two major areas of action:

1. Statistics from the National Statistical Plan 2025-2028

Data from the Property Register and Commercial Register will directly feed the following official statistical operations:

2. Integrated Business Information System (SIE)

The agreement supports the development of the Integrated Business Information System (SIE), a project that will integrate data from the Commercial Register—including financial statements deposits—to build a reference statistical business directory at the national level.

3. Eurostat Reservation on Gross National Income 2020-2024

The agreement also responds to a reservation made by Eurostat regarding the treatment of non-resident operators for VAT purposes, within the framework of the Gross National Income (GNI) verification process for the period 2020-2024. Access to registry data allows the INE to improve the quality of macroeconomic estimates that Spain submits to European institutions.

Economic and operational impact

For most companies, the direct impact is zero in terms of cost or administrative burden. The agreement does not require any action by commercial companies or owners of mortgaged properties.

However, there are three relevant operational consequences worth considering:

• Greater statistical traceability of companies: Data from financial statements deposits—which are already public in the Commercial Register—will be integrated into the SIE and can be used to develop sectoral, company size, and economic activity statistics with greater granularity.
• Reduction of future information burdens: By reusing existing administrative sources, the INE can dispense with direct surveys to companies for certain statistical operations. This is an advantage for SMEs that currently receive statistical information requests.
• Implications for non-resident operators: Foreign companies with registry activity in Spain (real estate operations, company incorporation, VAT-subject operations) fall within the scope of data analyzed in the context of the GNI 2020-2024 verification by Eurostat.

Who does it affect?

• Spanish commercial companies with data registered in the Commercial Register (incorporation, statutory amendments, annual financial statements deposits).
• Real estate owners and investors with mortgages, transfers, or executions registered in the Property Register.
• Non-resident operators with registry activity in Spain subject to VAT, in the context of the GNI 2020-2024 verification.
• Law firms, tax advisors, and management consultancies that process registry registrations for their clients: they should know that this data feeds official statistics.
• Financial institutions whose mortgage products generate registrations in the Property Register (data on mortgages established, modified, or executed).
• INE and College of Registrars as signatory parties to the agreement, with periodic supply and access obligations.

Practical example

A medium-sized construction company deposits its annual accounts in the Commercial Register each fiscal year. Until now, this data was public but did not flow in a structured way to the INE's statistical system.

With the new agreement, this data—along with that of thousands of companies in the sector—is integrated into the Integrated Business Information System (SIE). The INE can thus build statistics on business activity by sector, size, and territory without needing to send a statistical questionnaire to that company.

The result for the company: less likelihood of receiving direct statistical information requests from the INE, because its data is already available via administrative source. There is no cost, no adaptation period, no new obligation. But its registered financial data is now part of the national statistical system.

What should companies do now?

1. Verify that financial statements deposits are up to date: If Commercial Register data will feed official statistics, having accounts deposited correctly and on time is more important than ever. An incomplete or incorrect deposit can distort the statistical data associated with your company.
2. Review pending registry registrations: Any statutory amendment, change of administrator, or registrable act pending in the Commercial Register should be regularized. The data that circulates is what is registered.
3. Inform the tax department if there are operations with non-residents: Companies with non-resident partners, financiers, or counterparties that have carried out VAT-subject operations in Spain between 2020 and 2024 should be aware that those operations are within the scope of the GNI verification that Eurostat is reviewing.
4. Update external advisors: Law firms and management consultancies that process registry registrations for clients should know about this agreement to properly inform about the statistical use of registry data.
5. Do not expect new reporting obligations: This agreement does not generate new burdens for companies. If you receive any communication from the INE related to this agreement, verify it with the official source before acting.
