New AEAT Financial Inspection Director 2026: What Changes for Companies and Taxpayers

Key data

The body with the greatest impact on Spain's largest-scale tax inspections has just changed leadership. María Pilar Fernández Marín has been appointed Director of the Department of Financial and Tax Inspection at AEAT by Resolution of 25 September 2026, signed by the President of AEAT, Jesús Gascón Catalán, under the authority of Law 31/1990.

This department is not just any administrative body: it is the one that directs and coordinates the most economically significant inspection activities in Spain, with direct responsibility for checking large taxpayers, investigating significant assets and combating high-impact tax fraud. Whoever leads it effectively determines which sectors and profiles are prioritized in tax control plans.

What does this regulation establish?

The resolution is a formal appointment act: it designates María Pilar Fernández Marín as the new Director of the Department of Financial and Tax Inspection of the State Tax Administration Agency. The appointment is based on Law 31/1990 and is effective from 25 September 2026, although its publication in the BOE occurred on 30 September 2026.

The Department of Financial and Tax Inspection is the central body of AEAT responsible for planning, directing and coordinating the most economically significant tax verification and investigation activities. Its functions include combating tax fraud and supervising large taxpayers and significant assets.

Economic and operational impact

A change in the leadership of this department is not a mere administrative formality. In practice, the person holding this position has the ability to influence:

• The priorities of the annual Tax Control Plan: which sectors, types of taxpayers or tax structures are subject to greater scrutiny.
• The criteria for selecting taxpayers for inspection: risk profiles, turnover thresholds, intra-group operations, transfer pricing, etc.
• The approach of inspection activities: greater or lesser emphasis on agreed settlements, sanctions, or specific economic sectors.
• Coordination with other units of AEAT and with the Public Prosecutor's Office in cases of significant tax fraud.

For companies already in inspection procedures or that have received information requests, the change in leadership can result in variations in pace, approach or criteria in resolving their cases. It does not automatically change the outcome of procedures, but it can affect timelines and the intensity of activities.

Who does it affect?

• Large companies and business groups subject to verification by the Central Division of Large Taxpayers or by the Inspection Units of the Special Divisions.
• Taxpayers with significant assets under investigation or at risk of being so.
• Tax advisors and tax law firms managing active inspection procedures or advising clients with inspection risk.
• CFOs and financial directors of companies with complex operations: transfer pricing, restructurings, intra-group operations, international structures.
• Companies in historically priority sectors in tax control plans: technology, real estate, financial, e-commerce and digital economy.
• Taxpayers with ongoing inspection cases that may see variations in approach or resolution timelines.

Practical example

A technology sector company with turnover exceeding 20 million euros and operations with foreign subsidiaries—a typical profile of taxpayers managed by this department—has concrete reasons to review its situation:

• If it has an open inspection procedure on transfer pricing, the change in leadership may mean that the inspection team receives new instructions on valuation criteria or on the intensity of activities.
• If it is not currently being inspected, but its profile fits the sectors that the new leadership decides to prioritize in the next Tax Control Plan, it could receive information requests or be selected for verification in the coming months.

In both cases, the practical recommendation is the same: review the documentation supporting the most sensitive operations before any request arrives, not after.

What should companies do now?

1. Review the status of active inspection procedures: if your company has an ongoing inspection, communicate the change in leadership to your tax advisor and assess whether it is time to accelerate the submission of documentation or request meetings with the inspection team.
2. Audit documentation of sensitive operations: transfer pricing, related-party operations, recent restructurings and international structures are the usual focus areas of the Department of Financial and Tax Inspection. Ensure that supporting documentation is complete and up to date.
3. Follow closely the next Tax Control Plan: changes in department leadership are usually reflected in the priorities of the annual plan. When it is published, analyze whether your sector or profile appears among the objectives.
4. Consult with your tax advisor if your company fits the profile of large taxpayers or if it has operations with high inspection risk, to assess whether it is advisable to anticipate any voluntary settlement before an inspection activity arrives.
5. Keep your tax file updated: any corporate changes, structural changes or relevant operational changes that occurred in recent fiscal years must be properly documented and justified in the event of a future inspection.
