German Finanzamt Letter Types Compared 2026: Mahnung vs Aufforderung vs Anhörung vs Schätzbescheid (Foreign Seller's Guide)

If you opened a letter from a German Finanzamt and you don't read German, the first useful thing is to identify what kind of letter you got. Each type has its own deadline, its own consequence if ignored, and its own correct response. This guide compares the five letter types foreign sellers actually receive in 2026, side-by-side.

Visual decision tree: if you want to see how these letters chain together as an escalation ladder (and what each step costs if ignored), see the Finanzamt escalation timeline.

Aufforderung zur Abgabe: the filing request

An Aufforderung zur Abgabe is the Finanzamt asking for missing returns. Under § 149 AO, every taxpayer with a VAT obligation must file a UStVA (monthly preliminary VAT return) by the 10th of the following month. When the Finanzamt's electronic systems detect a missing filing, they send an Aufforderung. Typical 14-day window.

This is the cheapest letter type to receive. No penalty has been applied yet. The Aufforderung is the system asking you to catch up. For a foreign Amazon FBA seller who landed a Steuernummer in late 2025 and never started monthly filings, the Aufforderung is the most common first contact.

What to do: file the missing UStVA returns inside the 14-day window. With Vaytax, three months of catch-up filings is around €237 (3 × €79). The Aufforderung itself doesn't carry a penalty if responded to in time. Even where a small Verspätungszuschlag (late-filing surcharge under § 152 AO) lands later, it is almost always negotiated down or waived on a clean catch-up.

If ignored: the Finanzamt moves you from "missing filings" to "formally overdue" and sends a Mahnung. The longer you wait, the more Verspätungszuschlag accumulates, capped at 10% of the assessed VAT or €25,000.

Mahnung: the payment reminder

A Mahnung is a payment reminder. The Finanzamt has either assessed VAT that hasn't been paid, or converted unanswered filings into estimated VAT to collect. Under § 240 AO, late-payment surcharge (Säumniszuschlag) accrues automatically at 1% per started month on the unpaid amount. The Mahnung is the formal notice that the count is running.

For foreign sellers, the most common path is: Aufforderung → Mahnung → Anhörung → Schätzbescheid. The Mahnung sits in the middle. The 14-day window matters: respond inside it (either pay, or file an objection if the amount is wrong, or file the missing returns to replace the estimate) and the next escalation step is paused.

If ignored: a Vollstreckungsankündigung (enforcement notice) follows on the payment side, and on the filing side an Anhörung warning of an upcoming Schätzbescheid. Säumniszuschlag keeps accruing, no cap.

Anhörung: the hearing notice

An Anhörung is the § 91 AO right-to-be-heard notice. Before issuing an adverse Bescheid (a decision against the taxpayer), the Finanzamt must give the taxpayer a chance to state their side. For VAT compliance, the Anhörung is sent when the Finanzamt is preparing to issue a Schätzbescheid. Typical 14-day window.

This is the last cheap off-ramp before the situation becomes expensive. Respond properly (file the missing returns plus a brief written statement) and the Schätzbescheid never issues. Ignore it and it does, with a typical 2-5× actual-VAT estimate attached.

Why this letter matters: the cost difference between responding to an Anhörung and responding to a Schätzbescheid is roughly €237 vs €30,000-€75,000 for a €10K/month seller with three months unfiled. Same case, same underlying tax, one window earlier.

Schätzbescheid: the estimated assessment

A Schätzbescheid is an estimated tax assessment under § 162 AO. The Finanzamt has stopped waiting and picked a number itself, usually based on Amazon-reported gross sales under § 22f UStG, prior-year proxies, or industry averages. The estimate is intentionally high to motivate filing. Typical figures land at 2 to 5× actual VAT owed.

The window is longer than the others (30 days from receipt under §§ 347 ff. AO), but the stakes are also higher. Miss it and the Schätzbescheid becomes bestandskräftig (legally final). Collection enforcement begins, German bank accounts can be frozen, cross-border enforcement requests can be sent to your home country under EU Council Directive 2010/24/EU, and Amazon can be notified under § 25e UStG.

What to do: file an Einspruch (objection) inside the 30-day window, plus a parallel Aussetzung der Vollziehung (collection suspension under § 361 AO). Then file corrected UStVA returns based on your real numbers, replacing the estimate with reality. Typical reduction is 60-80% of the original estimate.

If ignored: the assessment is final, the Finanzamt collects, and the director becomes personally exposed under § 69 AO. Late objection (Wiedereinsetzung in den vorigen Stand under § 110 AO) is possible only in narrow circumstances like serious illness or postal failure.

Amazon §25e letter: the marketplace-liability route

The Amazon §25e letter is structurally a Schätzbescheid (same § 162 AO mechanic) but specifically triggered by Amazon's marketplace-liability reporting. Under § 22f UStG, Amazon must report seller VAT data to the Finanzamt. Under § 25e UStG, Amazon is jointly liable for unpaid VAT of marketplace sellers, which is why Amazon polices VAT documentation aggressively.

For foreign sellers, the §25e letter usually arrives after Amazon reported your German marketplace sales for years 2022-2025 and the Finanzamt found no matching UStVA filings. The assessment is built from Amazon's gross sales figures, which are usually much higher than actual VAT-relevant sales (returns, refunds, B2B reverse-charge transactions all reduce the real number).

What to do: file corrected UStVA returns from your real numbers (Amazon VAT Transactions Report download from Seller Central → Reports → Tax Document Library), file the Einspruch + Aussetzung der Vollziehung, negotiate the corrected assessment.

Common confusion: Aufforderung vs Anhörung vs Mahnung

Three letters that all give 14 days and all sound similar. The distinguishing question is what they ask for:

• Aufforderung zur Abgabe asks for missing returns. Filings, not money.
• Mahnung asks for overdue payment. Money, on VAT already assessed.
• Anhörung warns that an adverse Bescheid is being prepared. Gives you a window to state your side before it issues.

The three often arrive in sequence: Aufforderung (returns missing) → Mahnung (now overdue VAT to collect) → Anhörung (about to issue Schätzbescheid). Same case, three escalation stages.

Frequently asked questions

Which Finanzamt letter is the most serious?

A Schätzbescheid (estimated assessment under § 162 AO) is the most serious before enforcement begins. It carries the largest € exposure (typically 2-5× actual VAT owed) and the longest single deadline (30 days for Einspruch under §§ 347 ff. AO). Miss the window and the estimate becomes legally binding and collection enforcement starts. An Aufforderung zur Abgabe is the least serious if responded to inside its 14-day window.

Can I get multiple Finanzamt letters in the same month?

Yes. The escalation steps run in sequence but can compress when the Finanzamt is processing several missing periods at once. A foreign Amazon seller with six unfiled UStVA returns may receive an Aufforderung for some months, a Mahnung on prior unpaid VAT, and an Anhörung warning of an upcoming Schätzbescheid, all in the same week. Each letter has its own deadline and its own response action.

What is the difference between Mahnung and Aufforderung zur Abgabe?

An Aufforderung zur Abgabe asks for missing returns (the filings themselves). A Mahnung asks for overdue payment (VAT already assessed but unpaid, or accruing surcharges). The two often arrive in sequence for the same case: the Aufforderung first, then a Mahnung once the unanswered filing is converted into estimated VAT to collect. Aufforderung has no penalty yet; Mahnung adds 1%/month Säumniszuschlag under § 240 AO.

Do all Finanzamt letters give 14 days to respond?

No. Aufforderung zur Abgabe, Mahnung, and Anhörung typically give 14 days. A Schätzbescheid gives 30 days for the Einspruch (objection) under §§ 347 ff. AO. Some Amazon § 25e letters give 21 days. Always check the deadline written on the letter itself, since the Finanzamt occasionally sets shorter windows depending on the case posture.

Can I respond to a Finanzamt letter in English?

Legally no. § 87 AO requires correspondence with German tax authorities to be in German. The Finanzamt is permitted to disregard or set aside replies in other languages. In practice, a foreign seller responding in English may receive no acknowledgment and watch the deadline pass. A licensed German tax advisor handles the German correspondence, while you communicate with the advisor in English.
