ABSTRACT: If an Italian client has not paid your invoice on time, Italian law automatically entitles you to interest at 10.40% per annum and a flat €40 recovery contribution—no reminder, no court, no negotiation required. The EU Regulation that would have tightened these rules collapsed in early 2026, leaving the existing framework firmly in place. Here is exactly what you are owed and how to enforce it.

You sent the invoice. The Italian client acknowledged it. The payment term passed weeks ago. You have sent one polite email and received a vague assurance. Meanwhile, interest is accruing on that overdue balance whether your client knows it or not—and whether you have asked for it or not.

This is not a matter of negotiation. It is a matter of Italian statute.

The Rule That Works in Your Favour Without You Lifting a Finger

Italian Legislative Decree no. 231 of 9 October 2002 (Decreto Legislativo 9 ottobre 2002, n. 231), implementing Directive 2011/7/EU on combating late payment in commercial transactions, gives business creditors an automatic right to interest. From the day after the contractual or statutory due date, interest begins to run. You do not need to send a formal demand. You do not need to issue a notice of default. The clock starts itself.

The statutory rate for the second half of 2026 is 10.40% per annum. This is composed of the European Central Bank's reference rate of 2.40%—the rate in force on 1 July 2026—plus the mandatory margin of eight percentage points that Directive 2011/7/EU requires member states to apply to commercial transactions. Italy applies that margin without deduction. The rate is reset every six months by reference to the ECB rate published each 1 January and 1 July.

On top of interest, Article 6 of D.Lgs. 231/2002 grants a minimum flat-fee recovery contribution of €40 per overdue invoice, automatically, as compensation for the creditor's collection costs. This is not discretionary. A creditor who has issued five unpaid invoices is entitled to €200 in flat-fee costs before a lawyer has been instructed, before a court has been approached, and before a single enforcement step has been taken.

What Interest Rate Can I Charge an Italian Client for Late Payment?

The answer for the second half of 2026 is 10.40% per annum on the outstanding principal, accruing daily from the day after the due date.

If your contract with the Italian counterparty specifies a payment term, interest runs from the day that term expires. If the contract is silent on payment terms, the statutory default is 30 days from receipt of invoice or from delivery of the goods or performance of the service, whichever is later. Contractual terms can modify this period within limits, but a clause that purports to exclude or reduce the creditor's right to statutory interest is void under Article 7 of D.Lgs. 231/2002 if it is found to be grossly unfair—a concept the Italian Court of Cassation has interpreted expansively in favour of creditors.

The rate applies regardless of whether the creditor is based in Italy. A British company supplying services to an Italian client under a contract governed by Italian law—or, or where the contract contains no choice-of-law clause and Italian law applies by default under Rome I (Regulation (EU) 593/2008)—benefits from exactly the same statutory entitlement as an Italian supplier. This is the point that most foreign creditors miss entirely.

Unlike in most common-law jurisdictions, where interest on a late commercial debt does not run automatically and must either be claimed contractually or pursued as damages, Italian law (following the Directive's mandate) treats interest as an automatic statutory consequence of late payment. A UK creditor accustomed to relying on the Late Payment of Commercial Debts (Interest) Act 1998 should note that this Act does not follow them into Italian contracts. Once Italian law governs the relationship—by agreement or by operation of Rome I—it is D.Lgs. 231/2002 that applies, not the UK statute. The practical effect is similar, but the mechanism is different, and the rate for H2 2026 is substantially higher than the UK statutory rate.

Is the €40 Flat Fee per Late Invoice Automatic in Italy?

Yes. Article 6 of D.Lgs. 231/2002 provides for a minimum sum of €40 per transaction as soon as the debt becomes overdue. The provision implements Article 6(1) of Directive 2011/7/EU, which requires member states to ensure creditors obtain this minimum compensation automatically. Italy has not set a higher national floor, but the statute also allows creditors to claim reasonable additional costs of recovery if they exceed €40—legal fees, tracing costs, and similar expenses may be recoverable if documented.

The €40 is owed per invoice, not per debtor. A supplier who has three outstanding invoicesvoices can claim three separate €40 contributions, without issuing any formal demand. In practice, many foreign creditors either do not know this or omit it from their demand letters, effectively gifting the amount to their debtor. Including it explicitly in any correspondence or proceedings is straightforward and costs nothing.

Did the EU Replace the Late Payment Directive in 2026?

No—and the story of why not is instructive.

In September 2023 the European Commission published its proposal for a Regulation of the European Parliament and of the Council on combating late payment in commercial transactions (COM(2023) 533 final). Unlike the existing Directive, a Regulation would have applied directly and uniformly across all member states without the need for national transposition. More significantly, the proposal would have imposed a hard mandatory maximum payment term of 30 days for all B2B transactions, with no contractual derogation permitted.

Italian industry—and several other member states with established practices of longer credit terms in certain sectors—strongly opposed the mandatory cap. By early 2026, after two years of legislative negotiation, the proposal had effectively been abandoned. The European Parliament and Council did not reach agreement, and the Commission did not press the text forward. Directive 2011/7/EU therefore remains the governing instrument, and D.Lgs. 231/2002 remains the Italian transposition of it.

This matters for foreign creditors in two ways. First, the current framework with its variable rate and automatic entitlements is here for the foreseeable future—there is no imminent EU reform to wait for. Second, Italy was already in difficulty with the Commission over compliance with the existing Directive: in October 2023, the European Commission referred Italy to the Court of Justice of the European Union for failing to ensure that public authorities pay their commercial suppliers within the Directive's 30-day limit. That infringement proceeding (Commission v Italy, registered in late 2023) was still outstanding as of the date of this article, underscoring that Italy's record on timely payment—particularly in the public sector—remains a live issue.

Does Late Payment Interest Apply to B2G Contracts in Italy?

Yes, with stricter terms than apply to purely private transactions. For business-to-government (B2G) contracts—where the debtor is a public authority, a public hospital, or another contracting authority—Directive 2011/7/EU and D.Lgs. 231/2002 impose a maximum payment term of 30 days, extendable to 60 days only for public healthcare entities and universities where the longer period is expressly agreed and objectively justified. The rate of statutory interest is the same: ECB reference rate plus eight percentage points.

In practice, Italian public bodies have historically been among the slowest payers in the EU. The Commission's infringement proceedings against Italy reflect data showing that public-sector payment terms in Italy routinely exceed the statutory 30-day ceiling. For a foreign company contracting with an Italian public entity, this means that interest at 10.40% is likely accruing on a substantial portion of any outstanding balance—but collecting it against a public authority requires formal enforcement steps, typically beginning with a payment order (decreto ingiuntivo) issued against the authority by a competent Italian court, followed by attachment of assets (pignoramento) if necessary.

Protecting Your Position: What to Do With an Overdue Italian Invoice

The first practical step is to establish the governing law of your contract. If it is Italian law, or if Rome I defaults to Italian law, D.Lgs. 231/2002 applies and your entitlements are already crystallised. If the contract specifies a different governing law, the position is more complex and depends on whether the chosen law provides equivalent rights.

The second step is to document the due date and the overdue period precisely, because interest is calculated from the day after the due date. A payment that was due on 15 June 2026 and remains unpaid on 15 September 2026 has accrued 92 days of interest.

The third step is to include a formal request for statutory interest and the €40 flat fee in any written demand. Silence on this point does not forfeit the entitlement—it is automatic—but claiming it expressly signals awareness of Italian law and often accelerates settlement.

If informal steps fail, the payment order (decreto ingiuntivo) procedure under Articles 633–656 of the Italian Code of Civil Procedure (Codice di Procedura Civile) provides a fast-track route to an enforceable title, typically obtainable within weeks if the debt is documented. The interest and flat fee claims are included in the application. Once obtained, enforcement through attachment of assets (pignoramento) of the debtor's bank accounts or receivables can follow rapidly.

Debitor non praesumitur—the debtor is not presumed: the law presumes the debt is owed once the invoice is established. What Italian law does not do is pursue the debt for you.

As the legal theorist H.L.A. Hart observed in The Concept of Law, the distinction between rules that impose obligations and rules that confer powers is fundamental to understanding what a legal system actually does for its subjects. Italy's late payment statute is, in Hart's terms, a power-conferring rule: it places an entitlement in your hands. Whether you exercise it is a different question.

The colour palette contrasts the amber warmth of the office interior with the cool steel-blue of the urban exterior. The mood is quiet tension—the kind that comes from waiting too long for money that is already legally yours.

LOCAL NOTE:
1. Search intent targeted: informational with strong transactional pull — a foreign creditor who searches this phrase already has an unpaid Italian invoice and is assessing whether to act.
2. Local-market framing: the article explicitly contrasts Italian automatic interest accrual with common-law jurisdictions where interest must be contractually reserved or claimed as damages, and flags the Rome I trap for UK creditors who assume their own Late Payment Act applies abroad.
3. Italian terms kept untranslated: decreto ingiuntivo (kept in italics and explained as payment order on first use — retained because it has a specific procedural meaning that readers may encounter in Italian correspondence); pignoramento (translated as attachment of assets and explained — kept because it appears in Italian enforcement documents); Codice di Procedura Civile (kept in italics on first use with English equivalent — retained because practitioners searching Italian sources will encounter the Italian name).
