Voluntary Disclosure for Tax Evasion in Germany

By Dr. Julius Hagen, Attorney at Law

Voluntary disclosure is not a quick note to the tax office

A voluntary disclosure can prevent criminal tax proceedings. It can also become the starting point of an investigation if it is incomplete, blocked by statutory grounds or not supported by timely payment.

A voluntary disclosure is not a precautionary correction letter. It is a criminal-law relevant step. It may prevent punishment for tax evasion if the statutory requirements are met. It may also worsen the position if it is drafted too narrowly, filed too late or based on an incomplete reconstruction of the facts.

Typical triggers include

• undeclared foreign accounts,
• hidden cash income,
• incorrect VAT returns,
• concealed business revenue,
• false business expenses,
• inheritance issues,
• separations,
• shareholder disputes or
• an upcoming tax audit.

Before filing, it must be clear which taxes, years, persons and amounts are affected – and what the tax authority already knows or may be able to discover.

Voluntary disclosure has limited scope

Voluntary disclosure primarily concerns tax evasion under section 370 of the German Fiscal Code. It is not a general mechanism for eliminating all tax, criminal or professional risks.

Other tax offences, non-tax offences, professional consequences, corporate disputes or risks for other individuals must be assessed separately. This is particularly important where managing directors, shareholders, spouses, heirs or advisers are connected to the same facts.

Completeness determines whether disclosure works

A voluntary disclosure must correct, complete or submit the previously incorrect or missing tax information in a way that enables the tax authority to assess the tax correctly. A general statement that the taxpayer wants to regularise the past is not enough.

Partial corrections are particularly dangerous. If only one foreign account is disclosed while other accounts, capital income, years or tax types are left out, the disclosure may fail. The same applies in corporate cases where individual invoices are submitted, but the relevant VAT, income tax or corporate tax periods are not fully reconstructed.

Persons, roles and conflicts of interest

Completeness also concerns the persons involved. In cases involving spouses, heirs, managing directors, shareholders or factual participants, it must be clarified for whom the disclosure is intended to work. A voluntary disclosure does not automatically protect everyone connected to the facts economically, organisationally or for tax purposes.

Where several individuals are involved, joint preparation may be useful, but it may also create conflicts of interest. Who initiated, reviewed or signed the original tax filings can matter for the criminal-law assessment.

Blocking grounds – when the authority is already too close to the facts

A voluntary disclosure may be blocked if the tax authorities or criminal authorities have already taken certain steps. Relevant situations include

• notification of a tax audit order,
• the appearance of an official,
• notification that criminal or administrative fine proceedings have been opened, or
• discovery of the offence.

In practice, the chronology matters. When did which letter arrive? Which tax type is mentioned? Which years are covered? Who is the addressee? Are there control notifications, bank data, international information exchanges, bank inquiries or findings from a tax audit?

Tax audit and discovery of the offence

A tax audit does not necessarily block every possible fact. It may, however, close the room for voluntary disclosure in relation to specific years, taxes or persons. Conversely, even without a search, the authority may already have reached a point where the offence is discovered and the taxpayer had to expect discovery.

Reviewing blocking grounds determines whether voluntary disclosure can still be a route to immunity or whether the case has already moved into criminal defence.

Payment, interest and additional amounts

The declaration alone is not sufficient. The evaded taxes must be paid. Interest will often be due. In certain high-value or aggravated cases, an additional amount under German law may also become relevant.

If the amounts cannot be paid within the required timeframe, the protective effect may fail. Before filing, the expected amounts and the person able to pay them must be assessed realistically.

Voluntary disclosure or correction under section 153 of the German Fiscal Code

Not every tax correction is a voluntary disclosure. If a taxpayer later realises that a previous tax return was incorrect or incomplete, a correction duty may arise under section 153 of the German Fiscal Code. This type of error correction must be distinguished from voluntary disclosure intended to prevent punishment for tax evasion.

In practical terms, the question is what was known at the time of the original filing. Was the original tax return defensible from the taxpayer’s perspective, and was the mistake discovered only later? Or do emails, booking instructions, cash flows, internal notes or adviser correspondence suggest that tax-relevant facts were deliberately withheld?

When voluntary disclosure no longer works

Not every situation can still be solved through voluntary disclosure. If criminal proceedings have already been opened, a blocking ground applies or the facts can only be reconstructed in part, the focus changes.

The case then becomes a matter of defence in tax criminal proceedings. Tax loss, intent, responsibility, estimates, limitation periods, restitution and the procedural outcome remain important – but no longer as requirements of an effective voluntary disclosure.
