Search and Seizure — Act Immediately
The day of the search — known in professional circles as "the day the tax investigators arrive" — is a defining moment. In many cases, a house search is the first moment at which those affected learn of the investigation at all. Tax investigators appear early in the morning, without warning, armed with a search warrant and frequently also with an asset freezing order. In this exceptional situation, composure is critical. Make no statements. Sign nothing without legal review. Call a tax criminal defense attorney immediately. My role begins precisely here: I examine the search warrant for formal and substantive defects, ensure that all statutory formalities are observed and ensure that your rights are protected throughout. Current case law shows that investigating judges and public prosecutors frequently make errors — in particular in the reasoning of the grounds for suspicion, the temporal scope of the warrant and the proportionality of the measures ordered. These errors can render the warrant unlawful and, in the subsequent proceedings, give rise to exclusion of evidence.

Search and Seizure in Tax Criminal Proceedings — Your Rights, Your Defense
Searches and seizures are among the most frequent and most serious coercive measures in tax criminal proceedings. They serve to secure evidence and may affect residential premises, business premises, vehicles and even digital storage media. For those affected — whether private individuals or entrepreneurs — a search constitutes a massive intrusion into privacy and business operations.
However, not every search is lawful. The case law of the Federal Constitutional Court, the Federal Court of Justice and the regional courts demonstrates that investigators make errors. And these errors can be used in your defense.
Legal Basis for Searches
Searches in tax criminal proceedings are governed by the provisions of the Code of Criminal Procedure (StPO), in particular:
-
Section 102 StPO — Search of the suspect
-
Section 103 StPO — Search of other persons (third parties)
-
Section 105 StPO — Judicial order (judicial reservation)
-
Sections 94, 98 StPO — Seizure of evidence
-
Section 97 StPO — Seizure prohibitions (in particular for professional secret-holders)
-
Section 160a StPO — Special protection for attorneys (subsection 1) and limited protection for tax advisors (subsection 2)
As a general rule, every search must be ordered by a judge — Article 13 of the Basic Law, Section 105 StPO. Only where there is "imminent danger" may the public prosecutor or tax investigation authority act without a judicial order — an exception that is to be interpreted narrowly.
The Search Warrant — Minimum Requirements
A search warrant must satisfy certain minimum substantive requirements. The Federal Constitutional Court has repeatedly held that the warrant must describe the alleged offence in specific terms — BVerfG, decision of 5 May 2000 — 2 BvR 2212/99.
The warrant must contain:
-
Specific allegations — What act or omission is alleged? Which type of tax? Which period?
-
Evidence to be searched for — What precisely is being sought? "All documents" is insufficient — LG Bielefeld, decision of 22 November 2007 — 9 Qs 3437/07.
-
Temporal limitation — The warrant may not apply "at random" to any period whatsoever — BVerfG, decision of 4 April 2017 — 2 BvR 2551/12.
-
Proportionality — The search must be the last resort (ultima ratio). Would a written request have sufficed? — LG Osnabrück, decision of 10 November 2022 — 1 Qs 24/22.
Typical Errors by Investigating Authorities
The regional courts have declared numerous search warrants unlawful in recent years. The most frequent errors are as follows.
1. The "Blank Warrant" — Missing Specification of the Offence
The Regional Court of Nuremberg-Fürth has quashed search warrants in several decisions on the ground that they failed to specify the alleged offence with sufficient particularity — LG Nürnberg-Fürth, decisions of 15 May 2023, 7 June 2023 and 4 August 2023. A warrant that merely cites "Section 370 AO" and alleges "incorrect statements" without specifying which statements, in respect of which tax type, were incorrect is unlawful.
Practical lesson: a warrant that does not state precisely what was evaded, when and how, does not meet the minimum requirements of the rule of law.
2. Temporally Unlimited Investigation
In cases involving the purchase of tax data CDs, searches were ordered for periods in respect of which no specific data were available. The Federal Constitutional Court criticised this approach: where a CD contains data only for the year 2006, a search cannot automatically be ordered for all subsequent years — BVerfG, decision of 4 April 2017 — 2 BvR 2551/12.
3. Disproportionality
The Regional Court of Osnabrück declared a search of the Financial Intelligence Unit (FIU) unlawful because the public prosecutor could have obtained the information by means of a simple written request for disclosure — LG Osnabrück, decision of 10 November 2022 — 1 Qs 24/22.
4. Defective Searches at Professional Secret-Holders
Where searches are conducted at law firms or tax advisory offices, the critical question is which professional the documents are to be attributed to. Attorneys benefit from absolute protection against seizure pursuant to Section 160a(1) StPO. Tax advisors, by contrast, enjoy only relative protection under Section 160a(2) StPO — LG Nürnberg-Fürth, decision of 8 January 2025 — 18 Qs 27/24.
Your Rights During a Search
Even where you are taken by surprise by a search, you have rights:
Remain silent. You are not obliged to make any statements. Everything you say can be used against you.
Demand the search warrant. Read it carefully. Note the date, time and names of the officials present.
Call your attorney immediately. You have the right to legal assistance. The search does not have to be suspended, but you can receive advice by telephone.
Sign nothing without legal review. In particular, do not sign any records, waivers or declarations of consent.
Object to the seizure of specific documents. In particular where attorney correspondence or client documents held by professional secret-holders are concerned.
FAQ - Questions about the search
Must a search warrant precisely describe what I am alleged to have done, or do general formulations suffice?
A search warrant may not be a mere formality. It must "delineate" the alleged offence as specifically as possible. The Regional Court of Nuremberg-Fürth has held on multiple occasions that blanket formulations such as "made incorrect statements" or mere repetition of the statutory text — Section 370 AO — are insufficient. The warrant must specify which particular act or omission, at which point in time, is alleged to have resulted in the shortfall of which type of tax. Where this "description of the facts" is absent, the warrant is unlawful, as it affords the person concerned no means of oversight or defense.
Where investigators have initial suspicion relating to a specific year, may they also seize documents from other years?
No — not automatically. The Federal Constitutional Court has held that a search may not be extended "at random" to other periods. Where, for example, a tax data CD contains data only for the year 2006, the search warrant may not extend to subsequent years without further specific grounds. Such temporally unlimited investigation violates fundamental rights.
Is a search permissible where the authority could simply have requested the documents instead?
No. A search is a serious intrusion into privacy and may only be employed as a last resort — ultima ratio. The Regional Court of Osnabrück declared a search of an authority — the FIU — unlawful because the public prosecutor could have obtained the required information by means of a simple written request for disclosure pursuant to Section 95 StPO. The principle of proportionality must be observed without exception.
May a search be conducted at the premises of my tax advisor or attorney?
This depends on the status of the advisor. Attorneys benefit from an absolute seizure prohibition pursuant to Section 160a(1) StPO where they are acting as defense counsel. Tax advisors are subject to relative protection under Section 160a(2) StPO. In a recent decision of 2025, the Regional Court of Nuremberg-Fürth clarified that in a mixed practice — combining attorneys and tax advisors — a search is permissible where the suspicion relates only to the tax advisory part of the practice and no pure defense situation exists.
Does every search automatically interrupt the limitation period for my tax debts?
As a general rule, a search interrupts the limitation period pursuant to Section 171(7) AO. However, the Federal Fiscal Court has held that this only applies where the search warrant satisfies the minimum substantive requirements. A warrant that fails to specify the alleged offence, the relevant period or the evidence sought with sufficient particularity is so defective that it does not trigger a suspension of the limitation period. In such a case, the tax assessment may become statute-barred.
What happens if, as an entrepreneur, I have inadvertently become involved in a VAT carousel? Is that sufficient grounds for a search?
The threshold for initial suspicion is high in such cases. The Federal Constitutional Court requires particularly careful reasoning in complex matters such as VAT carousels. Mere objective involvement in a supply chain involving fraudsters is not sufficient. There must be specific facts indicating that the entrepreneur knew of the fraud or accepted it with conditional intent. Where these individual grounds for suspicion are absent, the search warrant is unconstitutional.
May the tax investigation authority take items during a search that are not specified in the warrant — for example "chance finds"?
The investigation authority is bound by the purpose of the search. The Tax Court of Cologne held that the removal of documents — such as receipt books — by means of direct compulsion is unlawful where they are not covered by the search warrant or where there is no connection to a tax criminal offence. A "fishing expedition" for further, unspecified evidence is impermissible.
Can I challenge the manner in which the officials conduct the search?
Yes. You may lodge a complaint. Even after the search has been completed, you have a legitimate interest in a declaration of unlawfulness — in particular given the serious intrusion into the fundamental right of inviolability of the home under Article 13 of the Basic Law, and for the purposes of potential rehabilitation. Investigating judges are moreover required to conduct an independent examination and may not simply adopt public prosecutor applications without scrutiny.
