ABSTRACT: Most foreign suppliers who sell to Italian companies accept that an unpaid invoice is a double loss: the revenue they never received and the output VAT they already paid over to the Italian Treasury. That assumption is legally wrong, and a March 2026 ruling of the Italian Court of Cassation makes it more wrong than ever. Italian Court of Cassation judgment no. 4900 of 4 March 2026 (<i>Cass. civ., sentenza 4 marzo 2026 n. 4900</i>) confirms that a supplier can claim a direct VAT refund from the Treasury even when the debtor's insolvency proceedings have dragged on for more than ten years and issuing a credit note has become procedurally impossible.

The money you paid on an invoice that went unpaid / was never paid

Suppose you supplied goods or services to an Italian company in 2014 or 2015, charged Italian VAT, declared it on your Italian VAT return, and paid it to the Treasury. Your customer then entered insolvency. You filed a proof of debt, received almost nothing in any distribution, and assumed that was the end of it. Ten years on, the proceedings have not formally closed. The VAT — in many cases tens of thousands of euros — remains trapped in the Italian system.

This is not a niche problem. Foreign suppliers selling B2B into Italy routinely carry Italian VAT on their balance sheets as an irrecoverable cost. The reason is procedural ignorance, not legal impossibility. The Italian Court of Cassation has recently confirmed the legitimacy of a direct refund claim where the taxpayer paid VAT without receiving payment from a debtor that has been subject to insolvency proceedings lasting more than ten years (sentenza n. 4900/2026).

Can I claim VAT back on an uncollected Italian invoice?

The short answer is yes, but the route depends entirely on when the Italian customer's insolvency opened and how much time has elapsed. Under Article 26 of the Italian VAT Act (DPR 633/72), as amended by Article 18 of Decree-Law No. 73 of 25 May 2021, bad debt relief can be claimed as soon as insolvency proceedings are opened, without having to wait for their unsuccessful conclusion. remove or integrate into preceding sentence Before it, a credit note could only be issued once the bankruptcy proceedings had concluded. Now the credit note may be issued at the beginning of the proceedings — which can save years of cash-flow loss.

The mechanics work like this. The supplier issues a corrective document (a VAT variation note, or nota di variazione) through Italy's electronic invoicing system. That note reduces the output VAT previously declared. The tax credit can then be used in the supplier's Italian VAT return or, where the supplier has no Italian VAT position to offset, claimed as a cash refund.

The complication arises for older, pre-reform insolvencies. For proceedings commencing from 26 May 2021, as amended by Legislative Decree no. 73/2021 of the Italian VAT Act, a credit note can be issued after the start of the proceedings to adjust the VAT. For proceedings commencing before 26 May 2021, suppliers must apply the old Article 26 and wait until completion of the insolvency process. That wait, in Italy's historically slow insolvency landscape, can exceed a decade.

How does Italian bad debt VAT relief work for foreign companies?

Unlike in most common-law jurisdictions — where bad debt relief for VAT or sales tax is either immediate upon writing off the debt or triggered within a defined short window — Italian law has historically required formal procedural milestones within insolvency proceedings before relief is available. Under Article 26(2) of DPR 633/1972, as historically interpreted by Italian courts and the Italian Tax Agency, the right arose only on proof that recovery was impossible, established after the final distribution from the insolvent estate or after a court decree declaring the insolvency procedure exhausted. That was the pre-2021 regime. It was also the rule the Italian Supreme Court found directly incompatible with EU law in earlier references to Luxembourg.

For EU-based foreign suppliers — UK businesses registered for VAT in Italy, Irish, Dutch, or German exporters with Italian VAT numbers — the EU VAT Directive is the structural backdrop. Article 90(1) of Council Directive 2006/112/EC of 28 November 2006 (the EU VAT Directive) requires Member States to reduce the taxable amount and, consequently, the VAT due whenever, after a transaction has been concluded, the taxable person receives none or only part of the consideration. The Court of Justice of the EU (CJEU) has consistently enforced this. In its decision in Case C-314/22, Consortium Remi Group, the CJEU confirmed once again that the reduction of the taxable amount in the case of total or partial non-payment is a fundamental right of taxpayers based on the provisions of Council Directive 2006/112/EC and cannot be abolished altogether. Italy, as an EU Member State, must provide that right. The CJEU reaffirmed that it is not required, for the exercise of the right to reduce the taxable amount, that insolvency proceedings be completed. On the contrary, the principle of neutrality prohibits a disproportionately long pre-financing of VAT by the supplier, provided that the supplier has taken all reasonable steps to discharge its function as tax collector for the state.

For non-EU suppliers — UK companies post-Brexit, US exporters, Australian businesses — the EU Directive does not apply directly to the claim mechanism, but it shapes what Italian domestic law must offer. The principle of fiscal neutrality means Italy cannot permanently confiscate VAT a supplier has already remitted on a transaction that was never paid for.

What is the time limit to recover VAT on a bad debt in Italy?

This is where precision matters and where the Cassazione 4900/2026 ruling is most immediately useful. The deadline for issuing the credit note is the deadline for submitting the yearly VAT return for the year in which the insolvency procedure commenced. Once that deadline has passed, it is no longer possible to file a supplementary declaration in the taxpayer's favour or to request recovery of the tax from the Italian Tax Authority via that route.

The deadline for issuing the variation note is peremptory. If it has elapsed, the right to deduction cannot be recovered via a supplementary declaration. However, where the impossibility of timely action arises from objective causes not attributable to the taxpayer, it is possible to attempt a refund claim under Article 30-ter of DPR 633/1972, provided the claim is presented within two years of the right arising.

The question that divided Italian courts for years was: what happens when both windows have closed because the insolvency itself has dragged on past ten years, yet no final distribution or closing decree has been issued? The supplier could not issue a credit note without a formal triggering event. The two-year supplementary return window had long since elapsed. The Treasury had received the VAT and seemed likely to keep it indefinitely.

The Italian Supreme Court, in judgment no. 4900 of 4 March 2026, recognised a taxable person's right to claim a VAT refund directly from the Treasury when it has not been paid by a customer that has been involved in insolvency proceedings for over ten years. A refund is allowed when it is not possible to issue a credit note to recover the VAT and when the impossibility of the creditor's claim being satisfied during the insolvency proceedings can be reasonably demonstrated.

The ordinary ten-year limitation period under Italian law — not the shorter two-year VAT procedural window — governs such direct refund claims. This is not a minor point. For companies that have ceased trading or been declared insolvent themselves, the Italian Court of Cassation has confirmed that the right to a VAT refund is subject to the ordinary ten-year limitation period and not the shorter two-year period applicable in a subsidiary and residual capacity.

Does the Italian insolvency of my customer let me reclaim output VAT?

Yes, but the mechanism and the timing depend on whether the insolvency opened before or after 26 May 2021. The table below sets out the two tracks in plain terms.

For post-May 2021 insolvencies, the path is the variation note, issued immediately on the opening of proceedings, declared in the Italian VAT return for that year, and claimed as a refund if no Italian output liability exists to absorb it. The deadline for issuing the variation note is 30 April of the year following the one in which the triggering event occurred, which corresponds to the submission deadline for the annual Italian VAT return pursuant to Article 26, second paragraph, of DPR 633/1972. Missing that date is not automatically fatal — but it closes the variation-note route and forces the supplier onto the harder, slower direct refund path.

For pre-May 2021 insolvencies still open after a decade, Cassazione 4900/2026 now confirms the direct Treasury refund route. Two conditions must be satisfied. First, issuing a credit note must be procedurally impossible — typically because the applicable deadline has elapsed or the statutory mechanism for the old-regime insolvency has not yet produced a distributable outcome. Second, the supplier must be able to demonstrate, with evidence, that its claim is realistically irrecoverable inside those proceedings.

Nemo locupletari debet cum aliena iactura — no one ought to be enriched at another's loss. That ancient maxim, which the philosopher and jurist Jeremy Bentham cited when arguing against unjust enrichment by the state, captures precisely the principle the Italian Supreme Court was applying. The Treasury had received VAT on a transaction for which the supplier never received the consideration. Retaining it indefinitely would be enrichment at the supplier's direct expense.

The EU VAT neutrality principle adds a constitutional dimension. All EU Member States must adhere to the EU VAT Directive (2006/112/EC), which grants the right to reduce VAT for non-payment. Article 90(2) allows Member States to set exceptions or additional conditions, but the Court of Justice of the EU has played a crucial role in striking down overly restrictive national measures that undermine the principle of fiscal neutrality. Cassazione 4900/2026 sits precisely at this intersection: it reads Italian domestic law through a lens of proportionality, refusing to let procedural deadlines permanently extinguish a substantive right where the impossibility of compliance was objectively caused by the length of the insolvency itself.

What a foreign supplier must do, and in what order

The first step is identifying which track applies. Establish the date on which your Italian customer's insolvency formally opened (it will appear on the Italian Insolvency Register, the Registro delle Imprese, or in the court order). If that date is after 26 May 2021, the credit-note route was available from the outset. If you missed the annual VAT return deadline for that year, seek Italian counsel on whether a supplementary declaration or a direct refund claim remains viable within two years of the missed window.

If the insolvency opened before 26 May 2021 and proceedings have been running for over a decade without a formal close, Cassazione 4900/2026 opens the direct refund route under Article 30-ter of DPR 633/1972 or the ordinary civil prescription rules confirmed in the Supreme Court's reasoning. You will need to gather your original invoice, proof of payment of the output VAT to the Italian Treasury, evidence of your participation in the insolvency proceedings (proof of debt filing), and documentation showing the proceedings remain open without dividend. The Italian Revenue Agency (Agenzia delle Entrate) may resist the claim initially. Refusal is challenged before the Italian Tax Court (Corte di Giustizia Tributaria).

One critical precondition that Cassazione 4900/2026 does not disturb: the VAT refund is available only where the output VAT was actually paid to the Treasury. A refund claim fails where the supplier declared the VAT on the invoice but never remitted it. Foreign suppliers who are VAT-registered in Italy must verify their payment records before lodging any claim.

Cost and timing: a direct refund claim through the Italian Revenue Agency, followed if necessary by Tax Court proceedings, realistically takes two to four years from lodging. Legal fees, translation, and Italian tax representation costs must be weighed against the recoverable VAT amount. Where the VAT sum exceeds approximately €10,000, the economics generally support pursuing the claim. Below that threshold, a cost-benefit analysis is advisable.

The one mistake to avoid above all others is inaction based on the assumption that the passage of time extinguishes the right. The whole point of Cassazione 4900/2026 is that proportionality and neutrality intervene precisely where procedural impossibility would otherwise produce unjust enrichment. The ten-year ordinary limitation period, running from the moment the right to a refund crystallised as a direct claim, gives suppliers a meaningful window — provided they move.
