Joint liability, guarantee failures, and the insolvency trap every US decision-maker must understand before entering Italy's VAT system
Your tax attorney told you to appoint an Italian fiscal representative and move on. That advice was half right.
Appointing a representative handles the paperwork. What it does not do is insulate your company from Italian VAT liability. The moment you sign the notarised proxy, you and your representative become jointly and severally liable for every euro of Italian VAT — yours and, under certain circumstances, theirs. If your representative is insolvent, Italy's tax authority comes to you. If your company fails to pay, Italy's tax authority can go to your representative. Most compliance blogs explain the appointment process. Almost none explain what happens the morning after something goes wrong.
This article is for the US CFO, general counsel, or business owner who has already entered — or is about to enter — the Italian market and needs to understand the liability architecture before signing anything.
Yes, unless your company has a permanent establishment in Italy. A US company selling taxable goods or services in Italy, without a branch or subsidiary established there, must appoint a fiscal representative under Presidential Decree No. 633/1972 (Decreto del Presidente della Repubblica 26 ottobre 1972, n. 633), Italy's principal VAT statute.
The representative — an individual, partnership, or company resident in Italy — must be appointed by a notarised letter of authority lodged with the Agenzia delle Entrate, Italy's national tax authority. The appointment gives your company an Italian VAT number (partita IVA) and, if you trade cross-border within the EU, registers you on the VIES system (VAT Information Exchange System).
Direct registration — filing form ANR/3 without a representative — is available only to companies established in countries that have a mutual-assistance agreement on VAT with Italy. The United States does not have such an agreement. A US entity has no choice: a fiscal representative is mandatory.
The representative does not merely file returns. Under Presidential Decree 633/1972, the representative assumes full responsibility for Italian VAT compliance, including submission of periodic returns, payment of VAT due, and correspondence with the Agenzia delle Entrate. Unlike a US agent relationship, the representative assumes liability as a statutory co-debtor.
omit or place in a footnote — where there are benefits, there are burdens. The fiscal representative receives fees for managing your Italian VAT position; the burden is that Italy's Civil Code and the VAT Decree make the relationship one of joint and several liability.
Article 17(3) of Presidential Decree 633/1972 provides that the fiscal representative is jointly and severally liable with the non-resident principal for all Italian VAT obligations. This is the rule that generic compliance content omits, and it operates symmetrically: the Agenzia delle Entrate can recover unpaid VAT from either party, in any proportion, without first pursuing the other party.
Unlike in the United States, where a registered agent or a tax preparer is an agent of the taxpayer and bears no personal tax liability, the Italian fiscal representative is a statutory debtor. The Agenzia delle Entrate does not need a court judgment to pursue the representative: it can issue a tax assessment notice (avviso di accertamento) against the representative directly and enforce it through attachment of assets (pignoramento).
The reverse is equally true. If your representative has built up a VAT liability to the Italian treasury — perhaps by misapplying the rules for other clients — and becomes insolvent before settling it, Italy's rules allow the authority to assess whether those debts are recoverable from the principals on whose behalf the representative acted. In practice, the authority targets solvent principals. You are a solvent US company. You are an attractive target.
Legislative Decree no. 13 of 12 January 2024 (Decreto Legislativo 12 gennaio 2024, n. 13), and two implementing Ministerial Decrees issued in 2024, introduced changes to the fiscal representative framework that most US companies have not yet taken on board.
Any non-EU entity registering for VIES through a fiscal representative must now post a bank guarantee of €50,000. Separately, the fiscal representative itself must maintain a sliding-scale guarantee: €30,000 for a small client book, rising to €2,000,000 for a large one. Both guarantees must be current. A representative whose guarantee has lapsed, or whose insurer has withdrawn cover, is technically no longer a qualifying representative under the new rules.
The practical consequence: if your representative failed to renew its guarantee — or if it restructured, entered insolvency, or simply closed — your Italian VAT registration is broken. The Agenzia delle Entrate does not automatically notify you. Your partita IVA may still appear active in a land registry search (visura catastale) or in the VIES database for some weeks, but you are no longer compliant. Any Italian VAT invoiced, collected, or deducted during that gap creates a liability that accrues interest and penalties from the date the irregularity began.
In 2026, at least one major provider — P&S VAT Compliance Services SRL — entered liquidation. Clients of that firm found themselves without a valid fiscal representative and needed urgent re-registration with a new appointment, a new bank guarantee, and in some cases, voluntary disclosure to regularise the gap.
The day your representative enters liquidation or ceases to operate, your Italian VAT registration becomes technically defective. There is no automatic grace period under Presidential Decree 633/1972. The Agenzia delle Entrate does not send a warning letter to your US address. The burden to monitor the representative's status and act immediately falls on you.
The immediate steps are: appoint a replacement representative, execute a new notarised letter of appointment, file it with the Agenzia delle Entrate, and confirm that the new representative holds a valid, current bank guarantee. The Agenzia delle Entrate will assign continuity of your partita IVA or, in some cases, issue a new one — which then requires updating across all your Italian counterparties, e-invoicing configurations, and customs registrations.
If there is a gap between your old representative's failure and your new appointment, the authority may open an assessment for that period. Penalties under Legislative Decree no. 471 of 18 December 1997 (D.Lgs. 18 dicembre 1997, n. 471) for late or missing VAT returns start at 120% of the tax due and can reach 240% in cases of repeated violation. Interest runs at the official rate from the date payment was due.
In our files, the most common mistake is discovering the representative's insolvency through a returned email or a bounced invoice rather than through proactive monitoring. By then, the gap is already two or three filing periods long, and a voluntary disclosure — which reduces penalties significantly — is still available but requires speed.
No. As noted above, direct registration under form ANR/3 requires a mutual-assistance agreement on VAT between Italy and the company's country of establishment. Italy has concluded such agreements with EU member states and a handful of third countries. The United States is not among them.
This contrasts sharply with what US companies experience in, for example, the United Kingdom, where a non-UK business can register directly for UK VAT without appointing a resident intermediary (though a tax agent is common in practice). The EU VAT framework — and Italy's domestic implementation of it — treats non-EU countries without a treaty differently and more stringently.
The only route for a US entity without an Italian permanent establishment is through a qualified fiscal representative who holds the required bank guarantee. There is no shortcut, no online self-registration portal, and no interim period of unrepresented compliance.
The gap between what US companies expect and what Italian VAT law requires is consistently the same: US decision-makers treat the fiscal representative as an outsourced compliance vendor, akin to a payroll processor or a registered agent. Italian law treats it as a co-debtor relationship with full joint and several exposure.
We see this misunderstood most acutely when US companies negotiate their fiscal representation agreements without any due-diligence clause on the representative's guarantee status. A well-drafted appointment letter should include a contractual obligation on the representative to provide annual written confirmation that its bank guarantee is current and at the required level, and an immediate-termination clause if that confirmation is not provided. Without it, the US company is flying blind on one of the prerequisites to a valid registration.
The next concrete step: before your next Italian VAT return is due, obtain written confirmation from your fiscal representative that it holds a valid bank guarantee at the amount required by the 2024 implementing decrees. If you cannot obtain that confirmation within five working days, treat your registration as at risk and seek replacement.
How long does it take to appoint a new Italian fiscal representative?
The notarised letter of appointment and the filing with the Agenzia delle Entrate typically take two to three weeks from instruction, assuming the new representative already holds its bank guarantee. Obtaining a new or updated bank guarantee from an Italian bank or insurer adds five to ten working days. Rush processing is possible but not guaranteed.
Can the Agenzia delle Entrate assess my US company directly, without going through the representative first?
Yes. Because the liability is joint and several, the Agenzia delle Entrate can address a tax assessment notice to the US company, to the representative, or to both simultaneously. It is not required to exhaust its claim against one party before pursuing the other. A US company receiving a formal assessment notice from the Agenzia delle Entrate has sixty days to respond before the notice becomes enforceable.
If we set up an Italian subsidiary, do we still need a fiscal representative?
No. An Italian subsidiary — a società a responsabilità limitata (SRL) or società per azioni (SpA) — is itself an Italian VAT taxpayer and registers directly for its own partita IVA. The fiscal representative requirement applies only to non-resident entities without a permanent establishment in Italy. Establishing a subsidiary eliminates the fiscal representative exposure but introduces separate corporate, employment, and transfer-pricing obligations.
