If a letter from a German Finanzamt announces a VAT examination of your Amazon sales, you have received an Umsatzsteuer-Sonderprüfung, a VAT special audit. For foreign sellers using Amazon FBA, these audits are common, repetitive, and almost always about the same thing: stock held in German warehouses and the VAT that should have been declared on the sales from it. This guide explains what the audit is, why foreign Amazon sellers get them, exactly what the Finanzamt checks, what it can cost, and how a licensed German tax advisor handles the response.

What is an Umsatzsteuer-Sonderprüfung?

An Umsatzsteuer-Sonderprüfung is a German VAT special audit: a targeted examination of a single taxpayer's VAT (Umsatzsteuer) for defined periods, ordered by the Finanzamt (the German tax office). Its legal basis sits in §27b UStG together with the general audit rules in §§193 ff. Abgabenordnung (AO). Unlike a routine desk query, it is a formal procedure: the Finanzamt issues a written Prüfungsanordnung (audit order) naming the tax type, the periods, and the auditor, and the examination ends with a written Prüfungsbericht (audit report) that can lead to amended VAT assessments.

The defining feature is its narrow scope. The auditor looks at VAT only, not income tax or corporate tax, and usually at a specific window of months or years. For a foreign e-commerce seller whose entire German footprint is VAT, that narrow scope still covers almost everything that matters.

How is it different from a Betriebsprüfung?

A Betriebsprüfung (general tax audit or field audit) is broader than a VAT special audit. Where the Umsatzsteuer-Sonderprüfung is limited to VAT, a Betriebsprüfung under §193 AO can examine several tax types and several years in one procedure: VAT, income or corporate tax, trade tax, and the underlying bookkeeping all at once. It is the wider, deeper review.

Foreign Amazon sellers almost always meet the VAT special audit rather than the full Betriebsprüfung, because a non-resident seller's German tax exposure is overwhelmingly VAT. The two procedures share the same backbone: both are announced by a Prüfungsanordnung, both give the taxpayer defined cooperation duties (§200 AO), and both close with a report. If you can resolve the VAT picture cleanly, you usually avoid the broader audit entirely.

Why foreign Amazon FBA sellers get audited so often

Foreign Amazon sellers get VAT audits in Germany more than almost any other group because their data is unusually visible and their cases are unusually repetitive. Several mechanisms stack on top of each other.

Marketplace reporting under §22f UStG

Under §22f UStG, Amazon and other online marketplaces must collect VAT registration data from their sellers and report seller transaction data to the German tax authorities. The Finanzamt therefore has an independent record of what each seller sold through the platform. When that record does not line up with a valid German registration, or with the VAT returns actually filed, the system flags a mismatch and a case opens.

Joint marketplace liability under §25e UStG

Under §25e UStG, the marketplace itself can be held jointly liable for a seller's unpaid German VAT. That liability is exactly why Amazon polices seller VAT status so aggressively and hands data to the Finanzamt. From the tax office's side, the same rule means there is a documented, collectible counterparty, which makes pursuing the case worthwhile. For a deeper look at this mechanism, see our guide to §25e UStG and Amazon marketplace liability.

Stock in a German warehouse is reachable

FBA inventory stored in a German fulfilment centre creates an immediate German VAT registration obligation with no minimum threshold, and that stock is physically in Germany. Unlike a purely cross-border seller, an FBA seller has assets the Finanzamt can identify and, if needed, act against. A repeatable trigger plus visible data plus reachable assets is why our in-house tax advisor sees these audits as a steady, recurring pattern, and why they are almost always Amazon sellers.

What the Finanzamt checks in an Amazon VAT audit

In an Amazon VAT special audit, the auditor reconciles the VAT you declared against independent data to confirm the German-taxable base was reported correctly and on time. The recurring checklist looks like this:

• Warehouse and stock records. When your inventory first entered a German fulfilment centre, how it moved between warehouses, and whether that arrival date matches your registration date. The first storage of goods in Germany is the classic trigger event.
• Marketplace transaction data (§22f / §25e). The Amazon transaction-level reports you hold are cross-checked against the data Amazon supplied to the authorities. Discrepancies between the two get questioned.
• Registration timing versus first taxable supply. The obligation runs from the first taxable supply, not from the day you eventually registered. Auditors look hard at the gap, because that gap is where back-VAT lives.
• Input VAT (Vorsteuer) claims. Any Vorsteuer you deducted must be backed by valid invoices. The auditor verifies the deductions and the documents behind them.
• Import VAT. For goods entering the EU through Germany, the auditor checks that import VAT was handled correctly and that any deduction matches the import documentation.
• Distance-sales thresholds and the transaction split. The auditor separates German-taxable B2C sales from intra-community supplies, exports, and B2B reverse-charge transactions. The €10,000 EU-wide distance-selling threshold and the correct treatment of each transaction type both get tested.

For the broader picture of how the underlying VAT obligation arises for FBA sellers, see our Amazon VAT in Germany guide and the dedicated Amazon FBA sellers overview.

Typical triggers

Most audits trace back to one of a small set of triggers. Sellers usually recognise their own situation in one of them:

• A mismatch between Amazon's §22f data and your filed returns. Reported sales exceed declared VAT, or there is no registration on file at all.
• Late registration. Stock sat in a German warehouse for months before you registered, leaving an undeclared back-period.
• Stopped filings. You registered, then the monthly UStVA filings lapsed (change of accountant, address, or a business pause).
• Unusual input VAT. Large or inconsistent Vorsteuer claims relative to declared turnover invite a closer look.
• Cross-border inconsistencies. Intra-community supplies or exports declared in a way that does not reconcile with customs or EU reporting data.

What back-VAT and penalties can result

The financial exposure from an Amazon VAT audit is the back-VAT plus statutory add-ons, and it scales with the number of periods involved. The components:

• Back-VAT. The core liability. Where registration was late, this is often retroactive to the first taxable supply, which can mean several years of German VAT on FBA sales.
• Verspätungszuschlag (late-filing surcharge, §152 AO). Up to 10% of the assessed tax per late return, capped per period, for returns filed late or not at all.
• Statutory interest (§233a AO). Roughly 1.8% per year on under-declared VAT for periods from 1 January 2019, the rate set after the Bundesverfassungsgericht struck down the older 6% figure.
• Penalty or criminal-tax exposure. Where the Finanzamt sees deliberate non-declaration rather than an oversight, a separate penalty procedure or a Steuerstrafverfahren can follow. This is the part where professional handling matters most.

If an estimated assessment (Schätzbescheid) has already been issued because returns were missing, a strict one-month appeal window applies. Our Schätzbescheid guide for foreign sellers covers that clock and the options in detail.

How to respond, and where a licensed tax advisor fits

The right response to an Umsatzsteuer-Sonderprüfung is to engage early, in German, with the correct statutory references, and to reconstruct the accurate German-taxable base rather than accept an estimate. Three things make a licensed German tax advisor (Steuerberater) the practical default for a foreign seller:

• Language and procedure. The Prüfungsanordnung, the correspondence, and any appeal must be handled in German and reference the right provisions. The Finanzamt will not translate or rephrase on your behalf.
• A point of contact in Germany. A foreign company without a German address benefits from a represented contact for service of documents and for the back-and-forth with the auditor. A Steuerberater fills that role.
• Reconstructing the correct numbers. Amazon's raw data over-states the German base: it mixes in shipments to other EU countries and B2B reverse-charge transactions that are not German-taxable. Pulling the genuinely German-taxable portion out of the transaction detail, and substantiating it, is where the assessment usually comes down.

How Vaytax helps

Vaytax is software plus a licensed German tax advisor (Steuerberater) who files. For an audit, the tax advisor reviews the Prüfungsanordnung, acts as your point of contact for the Finanzamt, reconstructs the correct German-taxable base from your Amazon transaction data, prepares any missing returns, and handles the correspondence in German. Because the work depends on how many periods are in scope, we scope each audit case and quote it individually, rather than quoting a fixed audit price. Once the audit is resolved, you can move onto routine ongoing compliance: €79 per month for the regular filings, or €1,199 per year all-in if you still need German VAT registration (the registration is included in that annual price). The €79 monthly plan covers routine ongoing filings.

Frequently asked questions

What is an Umsatzsteuer-Sonderprüfung?

An Umsatzsteuer-Sonderprüfung is a German VAT special audit: a targeted examination of one taxpayer's VAT (Umsatzsteuer) for specific periods, ordered by the Finanzamt (the German tax office) under §27b UStG and §§193 ff. AO. Unlike a routine desk check, it is a formal procedure announced in writing (a Prüfungsanordnung). It focuses only on VAT, not income or corporate tax, and is the tool the Finanzamt uses when marketplace data or warehouse records suggest a foreign seller's declared VAT does not match its actual German turnover.

Why do foreign Amazon FBA sellers get VAT audits in Germany so often?

Because their data is unusually visible to the Finanzamt and the cases are repetitive. Under §22f UStG, Amazon reports seller registration and transaction data to the German tax authorities, and under §25e UStG the marketplace can be held jointly liable for a seller's unpaid VAT. Stock held in a German fulfilment centre creates an immediate, threshold-free VAT registration obligation, and that stock is physically in Germany, so the audit has something to reach. When reported sales do not line up with filed returns, an audit follows almost automatically.

What does the Finanzamt check in an Amazon VAT special audit?

The auditor reconciles your declared VAT against independent data. Typical items: warehouse and stock movement records (when inventory first entered a German fulfilment centre), Amazon transaction-level reports cross-checked against the §22f data, the registration date versus the first taxable supply, input VAT (Vorsteuer) claims and the invoices behind them, import VAT on goods entering the EU, and the correct split between German-taxable B2C sales, intra-community supplies, exports, and B2B reverse-charge transactions. The goal is to confirm the German-taxable base was declared correctly and on time.

What is the difference between an Umsatzsteuer-Sonderprüfung and a Betriebsprüfung?

An Umsatzsteuer-Sonderprüfung is limited to VAT and to defined periods. A Betriebsprüfung (general tax audit or field audit) under §193 AO is broader and can cover several tax types and years at once. Foreign e-commerce sellers most commonly face the VAT special audit because their German exposure is almost entirely VAT. The procedural rights and obligations are similar: both are announced by a Prüfungsanordnung, both end in a report (Prüfungsbericht), and both can lead to amended assessments.

What can a German VAT audit cost a foreign seller in back-VAT and penalties?

It depends on how many periods were under-declared. The core exposure is the back-VAT itself, often retroactive to the first taxable supply rather than the registration date. On top of that the Finanzamt can add a late-filing surcharge (Verspätungszuschlag, §152 AO) of up to 10% of the assessed tax, statutory interest (around 1.8% per year on periods from 2019 under §233a AO), and in cases of deliberate non-declaration a separate penalty or criminal-tax procedure. The amounts scale with the volume and the number of unfiled or wrongly filed periods, which is why the response should be scoped case by case.
