Debt Collection in Austria: Inkasso Fee Caps and How to Dispute a Claim

Millions of consumers in Austria receive an Inkassoschreiben, a letter from a private debt collection agency (Inkassobüro or Inkassoinstitut) acting on behalf of a creditor, at some point. The letters are often worded urgently and add several separate fees on top of the original bill. Austrian law strictly regulates who may operate as an Inkassoinstitut, what it may charge, and what steps a debtor can take to dispute a claim.

This page explains the legal cap on Inkasso fees under the Inkasso-Verordnung, which charges are lawful and which are excessive, how to dispute a collection claim, and what happens if the underlying debt reaches court.

Who May Collect Debts in Austria: Inkassoinstitute and the Gewerbeordnung

Inkassoinstitute are one of the reglementierte Gewerbe (regulated trades) listed in § 94 Z 36 Gewerbeordnung 1994 (GewO). A company may only operate as an Inkassoinstitut if it holds a Gewerbeberechtigung for that trade, which requires proof of reliability and, for certain activities, a qualified Gewerbeinhaber.

A consumer who receives an Inkasso letter can ask the sender to confirm the name of the Inkassoinstitut and, if in doubt, contact the responsible Bezirkshauptmannschaft or Magistrat to confirm the Gewerbeberechtigung actually exists. A business collecting debts without this registration is acting unlawfully, which is itself one of the warning signs of a fraudulent letter covered further down.

What an Inkassoinstitut Can and Cannot Do

An Inkassobüro is a private company acting on a creditor's instructions. It has no special legal powers: it cannot enter a debtor's home, seize property, garnish wages, or freeze a bank account. Only a court, after a procedure that results in an enforceable title (Exekutionstitel), can authorise those measures.

In practice this means an Inkasso letter, however firmly worded, is a request for voluntary payment. It is not an enforcement action and it is not a court order. If a debt is genuinely owed and stays unpaid, the creditor's usual next step is a court Mahnverfahren, covered further down, not self-help enforcement by the collection agency.

The Legal Cap on Inkasso Fees: the Inkasso-Verordnung

The fees an Inkassoinstitut may charge are capped by a regulation, the Verordnung über die Höchstsätze der den Inkassoinstituten gebührenden Vergütungen (BGBl. Nr. 141/1996), referred to here as the Inkasso-VO. § 1 states that §§ 2 and 3 set Höchstbeträge, maximum amounts, and not fees the collector is automatically entitled to charge.

§ 2 of the Inkasso-VO sets a success-based percentage fee (Auftraggebergebühr) that the creditor, not the debtor, pays the Inkassoinstitut for a successful collection. This distinction matters: if a percentage figure is quoted in connection with an Inkasso file, it is often the fee the collector charges its own client, not a charge the debtor owes.

§ 3 sets the Schuldnergebühr, the costs that may be passed on to the debtor, tiered by the size of the original claim. The table below reproduces the current maxima in the tagesaktuelle Fassung of the regulation as verified on 22 July 2026.

A third reminder, and every reminder after that, is capped at the same maximum as the second reminder rate; the Inkasso-VO does not allow an escalating fee for each additional letter. The same second-reminder cap also applies to telephone collection calls, instalment agreements, deferrals and out-of-court settlement agreements (§ 3 Z 2).

Anschriftenerhebung, tracing a debtor's current address, is capped separately: up to €17.44 within the same municipality, up to €30.52 elsewhere in Austria, and up to €101.74 abroad, plus documented cash outlays (§ 3 Z 3).

These euro figures come from the 1996 regulation as converted to euro in 2002, and they have not been revalued since. They remain the current legal maxima in the tagesaktuelle Fassung, but they are old, and in practice some collectors charge above them, which is itself a lawful basis for a dispute.

A Worked Example: What a Collector May Lawfully Add

Take an original unpaid invoice of €500, which falls in the "over €364 to €727" tier of § 3. If two reminders go unanswered, the maximum lawful Bearbeitungskosten is 17% of €500, or €85.00. The first reminder is capped at €24.71 and the second at €27.62.

Added together, the maximum lawful collection cost on top of the €500 debt is €137.33, bringing the total the debtor could lawfully owe to €637.33, before statutory default interest. Any amount charged above these tiered maxima, for that claim size and that number of reminders, is not permitted by the Inkasso-VO.

The Arbeiterkammer Niederösterreich publishes a real-world example of an unlawful bill: an unpaid €40 invoice inflated to €145 through five separate reminder fees of €11 each, plus €90 in Inkassokosten. On a €40 claim, in the "up to €73" tier, Bearbeitungskosten are capped at €20.35 and only the first two reminders may be charged at their own rate. The Arbeiterkammer describes that combination as disproportionate and rechtswidrig (unlawful).

Which Fees You Only Owe if They Are "Zweckentsprechend"

The Inkasso-VO sets ceilings; it does not create an automatic entitlement to charge them. The underlying legal basis for charging any collection cost to a debtor at all is § 1333 Abs 2 ABGB, which allows a creditor to claim, alongside statutory interest, only the necessary costs of appropriate (zweckentsprechend) out-of-court collection or recovery measures, provided these stand in a reasonable proportion (angemessenes Verhältnis) to the claim being pursued.

In practice this necessary, appropriate and proportionate test is a debtor's main lever for disputing an Inkasso bill, alongside the numeric caps in the Inkasso-VO itself. A collection cost can fail this test even where it sits under the VO ceiling, for example where the underlying debt is small, disputed, or already settled.

How to Dispute an Inkasso Claim

Do not pay quickly simply because a letter is worded urgently. Check first whether the claim itself is valid: whether a contract exists, whether the goods or service were actually delivered, and whether the debt has already been settled, for example by a return or a Widerruf (contract withdrawal) that the creditor never registered.

If the underlying claim, the fee amount, or both are wrong, dispute the bill in writing (schriftlich bestreiten) and send a copy to the original creditor as well as the Inkassoinstitut. Avoid making a partial payment or signing an instalment plan while the claim is genuinely unclear, since this can be treated as an acknowledgement of the full debt and weaken a later dispute.

The Arbeiterkammer publishes a free sample objection letter (Musterbrief) for unjustified Inkasso claims, and its Konsumentenberatung reviews a letter's authenticity on request. Warning signs of a fraudulent Inkasso letter include missing or vague information about the creditor or the underlying claim, a request to transfer money to a foreign account, and obvious spelling or translation errors.

When It Goes to Court: the Mahnverfahren

Austrian law does not require a creditor to send an Inkasso Mahnung before suing; a lawsuit can be filed directly. For monetary claims up to €75,000, § 244 ZPO lets a court issue a Zahlungsbefehl (conditional payment order) without a hearing and without first questioning the defendant.

The Zahlungsbefehl gives the debtor 14 days to pay the claim plus interest, or four weeks to lodge a written Einspruch (objection). If no objection is filed in time, the payment order becomes enforceable exactly as if a court had ruled against the debtor after a full hearing, even if the underlying claim was disputable.

Filing an Einspruch cancels the payment order and the case proceeds to an ordinary hearing where both sides are heard. A debtor who believes a claim is wrong, or only partly correct, should use the objection period, for example by visiting the district court's Amtstag (office hours) or consulting a lawyer, rather than letting the deadline pass.

Only once a court claim results in an enforceable title does enforcement under the Exekutionsordnung become possible, including wage garnishment, seizure of movable property, or a forced sale of real estate. If a debtor cannot realistically pay a debt at all, including after a court judgment, Austrian law also provides a structured route out through personal insolvency.
