Unannounced German VAT Inspection (Section 27b): When Tax Officers Ring the Bell

An inspection is not an audit. But it often decides whether one begins.

Two officers arrive at reception without warning, show their identification and ask to “take a brief look at the VAT situation”. This is the Umsatzsteuer-Nachschau — the unannounced VAT inspection under Section 27b of the German VAT Act (UStG). It is a legitimate tool against fraud structures, especially in sectors exposed to carousel risk. That is right and proper. But it is also the most underestimated high-risk moment in VAT compliance: an informal visit with no notice, in which the authority’s first version of the facts takes shape, data changes hands — and, overlooked by many, the door to a penalty-free voluntary disclosure can close. Companies that know the limits of the inspection and use their rights precisely lose nothing. Companies that improvise hand the administration the frame within which a special audit, a tax fraud investigation and a Section 25f assessment will later argue.

What the inspection may do — and what it may not

Section 27b UStG allows tax officers entrusted with VAT matters to enter business premises during business and working hours, without prior notice, to establish facts that may be relevant for VAT. Typical triggers: verifying that a newly registered company actually exists, checking input-VAT refund claims, comparing stock and premises against the declared business model.

Just as important is what the inspection is not. It is not a formal external audit (Außenprüfung): there is no audit order, no defined audit period, no formal audit procedure. And it is emphatically not a search (Durchsuchung): officers may enter and look, but they may not open cupboards against your will, comb through rooms systematically or hunt for documents. If the authorities want to search, they need a criminal-procedure basis — normally a judicial warrant. Private living quarters may be entered against the occupant’s will only to avert imminent danger to public safety and order; the home enjoys heightened constitutional protection in Germany.

On request, you must produce records, books and business papers relevant to VAT and provide information. Since the rules were tightened with effect from 2020, the inspection also extends to electronically stored records: officers may demand access to the stored data and use your data-processing system for that purpose. This is where much is decided in practice — a company without a data filter shows more than the law requires. The access reaches as far as VAT relevance, and no further.

The junction: from inspection to special audit — and to investigation

Section 27b(3) UStG contains the real leverage: if the findings give cause, the authority may switch directly to an external audit — usually a special VAT audit — without issuing a prior audit order. The transition must be notified in writing; it is an administrative act that can be challenged, but remedies generally have no suspensive effect. The audit continues while you dispute it.

The second track leads into criminal territory. Audit units and the tax fraud investigation service (Steuerfahndung) are not separate worlds: internal administrative guidelines provide for early involvement of the penalty units, and whatever surfaces openly during an inspection can establish initial suspicion. Practitioners therefore rightly describe inspection and special audit not as mere preliminaries but as the first stage of a crisis. If matters escalate — search warrant, seizure, questioning as a suspect — the 72-hour emergency playbook applies.

Once criminal or administrative-penalty proceedings have been initiated, the legal position shifts fundamentally: duties to cooperate in the tax procedure may no longer be enforced with coercive means (Section 393 of the German Fiscal Code, AO). No one is required to incriminate themselves. That is why classifying the visit correctly — routine inspection, audit, or an already suspicion-driven exercise? — is not a formality. It is the first defence decision.

The underestimated trap: the voluntary-disclosure block

Since 2015, the appearance of an officer for a VAT inspection has been a statutory blocking ground: for the taxes concerned, a penalty-releasing voluntary disclosure (Selbstanzeige, Section 371 AO) is barred while the inspection lasts. Anyone hoping to “tidy up” old errors on the occasion of the visit is too late — and risks producing an ineffective disclosure that serves the authorities as evidence. The practical rule of caution: from the moment the officer shows identification, no correction communication without advice. Whether and how a correction can be made after the inspection ends — as a simple correction under Section 153 AO or as a voluntary disclosure — is the most important junction in German correction law and belongs in professional hands before anything reaches the tax office.

Your rights during the visit — used with precision

The statutory limits translate into a clear protocol. It is not a confrontation programme — cooperation within the legal frame is usually the best defence. But the frame must hold:

1. Verify identity and purpose. Ask for service IDs, note names, ask what the inspection concerns. There is no inspection “into the blue”; a VAT connection must be apparent.
2. Assign roles. One designated spokesperson (management or tax function) handles the conversation; everyone else politely refers to that person. Spontaneous statements by warehouse or sales staff are the most common source of later misunderstandings — employees are not obliged to give statements on the spot.
3. Keep your own minutes. Who attended, what was asked, what was produced, what was copied or exported? Your record is often the only counterpart to the official file note.
4. Provide data within the statutory scope. Meet disclosure duties — for VAT-relevant matters. No blanket access to the entire system, no “voluntary” full exports without review.
5. Name limits without blocking. No searching, no living quarters, no coercion once proceedings are initiated. If a line is crossed, object and document; the dispute is resolved later, not at the office door.
6. Call your advisers. Involving tax and criminal-defence counsel during the visit is permissible and routine. It does not irritate professional inspectors.

After the visit: the follow-up decides the next round

When the officers leave, the visit ends — the matter does not. Within 24 hours the debrief belongs on the table: finalise your own minutes and have every participant countersign them; record precisely which documents and data exports were handed over; collect and prioritise open promises (“we will send that on”) — nothing leaves the house unreviewed. Then the risk diagnosis: which findings did the officers address? Were there questions about particular suppliers, prices or transport routes — that is, about the building blocks of a later “should have known” allegation? Depending on the result, the course is set: a clarification to the office, an orderly correction review, or quiet preparation for the audit order that may follow. One typical trigger deserves special mention: refund positions. Where sizeable input-VAT surpluses are pending, the inspection often decides whether the office pays out, withholds or escalates — the visit is then a decision about liquidity, not a walk-through. And finally the system view: every inspection is an involuntary stress test of your control system. Whatever was missing during the visit — the current VAT ID confirmation, the transport document, the documented approval — gets closed now, not when the special audit asks the same question.

Preparation begins before the doorbell

The honest message: during the visit itself you can only manage what was organised beforehand. A role model for unannounced visits, a data-access concept, an emergency card at reception and a maintained Evidence Pack — checks, timestamps, approvals for every risk-bearing deal — turn the surprise into a routine event. Because the inspection tests exactly what Section 25f of the German VAT Act will ask later: can this company show whom it checked, when, and with what result? Whoever starts answering that question after the doorbell rings answers too late. The VAT CMS Quick Scan shows in ten questions whether your organisation is ready for this moment.

And if the visit has already happened — perhaps gone badly? Then: do not send follow-ups, “clarifications” or documents until the situation is structured. The VSK team of German attorneys and tax advisers reconstructs the visit, secures your own version of the facts and decides the next steps with you — from the response strategy towards the inspector to the correction junction.
