As of 11 October 2026, the Spanish Supreme Court is examining whether the Tax Agency can issue a new tax assessment for the same facts and periods after a previous settlement was annulled by the courts, but on different legal grounds. The case addresses the tension between legal certainty (res judicata) and the Administration’s power to correct errors. A ruling against the taxpayer would allow successive inspections for the same operations.
Key Takeaways
- Annulment Not Final: An annulled settlement may not close the matter if the Administration identifies an alternative legal basis for the same tax liability.
- Res Judicata Scope: The Court will define whether the annulment’s reasoning binds the Administration to the factual determinations or only the specific legal qualification.
- Strategic Impact: Taxpayers winning on procedural grounds may face renewed assessments; comprehensive defense on all potential grounds is advisable.
