Tax Assessment and Criminal Tax Proceedings in Germany

By Dr. Julius Hagen, Attorney at Law

Parallel tax and criminal proceedings in Germany

German tax criminal cases often involve two procedures at the same time. The tax office wants to assess the tax. The criminal tax authorities or prosecutors examine whether a criminal offence may have been committed. Any response must be assessed by reference to both procedures.

Two procedures, two standards

The tax assessment procedure is about determining the correct tax. The tax authority may request documents, require cooperation and draw tax conclusions if the facts remain unclear. If records are missing or accounting entries appear unreliable, the authority may estimate the tax basis.

Criminal proceedings follow a different standard. The authorities must prove that a tax-relevant fact was declared falsely or incompletely, that this led to a tax reduction or an unjustified tax benefit, and that the suspect acted intentionally. An additional tax assessment does not replace this criminal-law analysis.

Section 393 of the German Fiscal Code and the limit of compelled cooperation

The difficult interface is addressed by Section 393 of the German Fiscal Code. The taxpayer generally remains subject to cooperation duties in the tax assessment procedure. At the same time, a suspect must not be forced by coercive tax measures to incriminate themselves in relation to a tax offence or tax-related administrative offence.

This does not justify a purely passive approach in every case. The tax procedure continues, tax assessments may still be issued and adverse tax consequences may arise if information is missing. The decisive issue is classification: which information concerns only the tax assessment, which information may support the criminal allegation and which information cannot be compelled

Statements may define the case

Explanations given after the event are particularly sensitive. A statement explaining why a payment was treated as a business expense may also address the economic purpose of the payment. An explanation of a foreign company may disclose ownership structures, decision-making routes or knowledge. Comments on cash irregularities may unintentionally confirm organisational responsibility.

This risk is not limited to personal statements by the suspect. Letters from tax advisers, replies from accounting staff, internal summaries or later-submitted spreadsheets may acquire their own significance in the criminal case. Before responding, it should be clear not only whether the tax content is correct, but also what personal or corporate attribution may follow from the statement.

Tax estimates, payment and criminal exposure must be separated

A tax estimate can have serious financial consequences. It may lead to additional tax, interest, amended assessments and follow-up issues for further years. For the criminal case, however, a different question matters: which specific tax loss can be supported under criminal procedure standards?

This distinction is especially important in cash-heavy businesses, defective cash registers, mixed private and business expenses, foreign structures, intercompany accounts or incomplete records. The tax authority may work with probabilities for assessment purposes. In criminal proceedings, the incriminating interpretation must be tied back to a reliable factual basis.

Correction, subsequent declaration and defence must not be confused

Once errors are identified, the immediate question is often whether a correction or subsequent declaration should be made. That question must not be answered from a tax perspective alone. A correction under German tax law, a possible voluntary disclosure and defence after the opening of criminal proceedings each follow different rules.

This page does not set out the full requirements for voluntary disclosure or the full elements of tax evasion. The decisive preliminary question is the procedural position of the client. Only then can it be assessed whether a statement may correct the tax position, have a penalty-avoiding effect, neutralise risk or create additional exposure.

Companies need a controlled procedural track

In companies, knowledge is often distributed among several people. Management knows strategic decisions, the tax department knows the filing position, accounting staff know individual entries and the external tax adviser often communicates with the tax authority. Investigators may try to connect these levels.

Uncoordinated answers may lead to a tax explanation later being treated as a statement about responsibility, organisational fault or individual intent.
