Received a Mahnung? Read this before you pay.

What is a Mahnung?

A Mahnung is a formal payment reminder. A company or creditor sends it when you have not paid an invoice by the due date. It restates what you owe, may add reminder fees (Mahngebühren) and late-payment interest (Verzugszinsen), and gives you a new deadline to pay.

It is serious — ignoring it can lead to debt collection or court — but a Mahnung itself is not a court document, not an enforcement order, and not the same as a Mahnbescheid in a yellow envelope. Most Mahnungen are routine: millions are sent every year for unpaid phone bills, insurance premiums, online orders, and utility invoices.

Who sends them?

Almost any creditor can send a Mahnung after a missed payment:

• Mobile and internet providers (Telekom, Vodafone, O2)
• Energy companies (Strom, Gas) and insurers
• Online shops, subscription services, and gyms
• Landlords or property managers (for rent or Nebenkosten)
• Local authorities and the Finanzamt — often as a step before harsher measures

The letter always comes from the creditor or their billing department, not from a court.

What the letter usually contains

A typical Mahnung includes:

• Rechnungsnummer — reference to the original invoice you missed
• Hauptforderung — the underlying amount still owed
• Mahngebühr — a reminder fee (often €2.50–€5 for a standard letter; higher on 2nd/3rd reminders)
• Verzugszinsen — statutory late interest, usually only after you are formally in default (Verzug)
• A new payment deadline — often 7–14 days; treat it as real even when it feels like pressure
• A threat of further steps — Inkasso, credit bureau reporting, or legal action if you do not pay

1st, 2nd, and 3rd Mahnung

Creditors often escalate in stages:

1. 1. Mahnung — first reminder after the invoice due date. May add a small Mahngebühr.
2. 2. Mahnung — stronger wording, sometimes a higher fee. Still from the original creditor.
3. 3. Mahnung (letzte Mahnung) — final warning before the file goes to Inkasso or a lawyer. Language gets urgent; deadlines get shorter.

Not every creditor sends three separate letters — some jump to Inkasso after one Mahnung. The numbering on your letter tells you where you are in the chain. A "letzte Mahnung" should be taken especially seriously.

Mahnung is not Abmahnung

These words look similar but mean completely different things. An Abmahnung is a formal legal warning — often from a lawyer — demanding you stop an alleged infringement and sign a declaration. A Mahnung is simply "you still owe money on this invoice."

If your letter mentions Unterlassungserklärung, Streitwert, or copyright, you probably have an Abmahnung, not a Mahnung. If it references an unpaid Rechnung and Mahngebühren, it's a Mahnung.

Mahnung vs Inkasso-Brief vs Mahnbescheid

Think of a ladder — each step is more serious:

1. Mahnung — creditor reminds you directly. No court involved.
2. Inkasso-Brief — debt sold or assigned to a collection agency. Still not a court order, but fees multiply and Schufa risk increases.
3. Mahnbescheid — court payment order in a yellow envelope. You have 14 days to file Widerspruch or it becomes enforceable.

Paying or disputing at the Mahnung stage is almost always cheaper and simpler than waiting for Inkasso or court.

Are Mahngebühren legitimate?

Creditors may charge reminder fees, but they are not unlimited. Under German law (BGB), fees must reflect actual costs or agreed contract terms — flat "Pauschalen" of €10–€25 on a first reminder are often challenged successfully, especially for consumers.

What is usually defensible:

• A modest fee for a paper reminder if your contract or AGB allows it
• Verzugszinsen once you are in Verzug (typically after a second reminder or a specific Mahnfrist in the contract)

What to question in writing:

• Multiple Mahngebühren for the same overdue period
• High "Bearbeitungsgebühren" with no contractual basis
• Interest charged before you were properly in default

When to pay, when to dispute

Pay (or arrange a plan) if the underlying invoice is correct, you received it, and you simply missed the date. Paying the Hauptforderung stops escalation; you can still dispute excessive Mahngebühren separately in writing.

Dispute in writing if:

• You already paid — send proof (Überweisungsbeleg, Kontoauszug)
• You never received the original invoice (Rechnung nicht zugegangen)
• The amount is wrong, the service was not delivered, or you cancelled properly
• The claim may be time-barred (verjährt) — most consumer debts expire after three years

Even when disputing, respond before the deadline. Silence is read as acceptance.

What to do — step by step

Step 1: Find the original invoice. Match Rechnungsnummer, date, and amount. Check your bank statements.

Step 2: Separate principal from extras. Note Hauptforderung, Mahngebühr, and Verzugszinsen separately.

Step 3: Respond in writing before the deadline. Email is fine for a first reply; for disputes, use Einschreiben mit Rückschein (registered mail with return receipt).

Step 4: Pay or negotiate. If you owe it, pay the principal promptly. If you need time, ask for a Ratenzahlung (payment plan) — many creditors agree if you contact them early.

Step 5: Keep records. Save every letter, payment proof, and your replies. You may need them if the case goes to Inkasso.

What happens if you ignore it?

Ignoring a Mahnung does not make the debt disappear. Typical escalation:

• More Mahnungen with higher fees
• Handover to an Inkassounternehmen — see our Inkasso-Brief guide
• Negative Schufa entry if legal conditions are met (usually after repeated notice and no dispute)
• Mahnverfahren at court → Mahnbescheid in a yellow envelope

The earlier you act, the more options you keep.
