On 19 August 2026, the Federal Fiscal Court (Bundesfinanzhof, BFH) issued a landmark ruling (X R 8/25) clarifying the precise conditions under which the statute of limitations for tax assessments is suspended when a tax criminal investigation (Steuerfahndung) begins. The decision addresses a critical procedural intersection between tax assessment law and criminal tax procedure, providing much-needed certainty for taxpayers and practitioners regarding the temporal boundaries of tax liability. The Court examined the requirements of Section 171(4) of the German Fiscal Code (AO), which stipulates that the limitation period is suspended from the moment a formal investigation is initiated against a specific taxpayer.
Key Takeaways
- Formal Initiation Required: The BFH held that a mere preliminary inquiry or informal suspicion does not trigger the suspension; a formal order initiating the investigation procedure (Ermittlungsverfahren) under the Code of Criminal Procedure (StPO) or the Fiscal Code must exist, naming a concrete suspect.
- Objective Connection to Tax Matter: The investigation must objectively relate to a specific tax type and assessment period; investigations into unrelated crimes do not suspend the limitation period for tax assessments.
- Retroactive Effect Clarified: The suspension takes effect from the date of the formal initiation order, not from the date of the underlying acts or the eventual conviction, protecting taxpayers from indefinite exposure.
