VIES Bond Authorization: What Non-EU Companies Must Know About Power of Attorney

Many non-EU companies seeking VIES registration in Italy discover their bond applications have been rejected or delayed. The root cause is rarely technical: it is a misunderstanding about the scope of authority granted to a tax representative. The Italian Tax Authority (Agenzia delle Entrate), through its Milan Provincial Office, has issued formal guidance clarifying a critical distinction that every non-resident operator must understand before submitting documentation. If you are still mapping out the broader process, our guide on VIES registration in Italy with the Revenue Agency provides the full procedural context.

The core compliance issue

Companies frequently assume that simply appointing a tax representative under Italian law automatically grants that representative the power to sign the VIES bond on their behalf. This assumption is incorrect, and acting on it leads to rejected applications, processing delays, and in some cases temporary loss of intra-community trading eligibility. Before going further, it is also worth understanding who is actually required to provide a guarantee bond for VIES registration.

Under Article 17, paragraph 3, of Italian Presidential Decree 633/1972, when a non-resident company appoints a tax representative, that appointment establishes a representation mandate within Italian territory. However, this mandate has narrowly defined boundaries — it does not, by itself, include the power to execute a financial guarantee bond on behalf of the company.

The legal distinction: appointment does not equal authorization

Tax representation and the power to sign binding financial documents are two distinct legal authorities. The first does not automatically include the second. This stems from Italian civil law principles governing agency relationships (rapporto di mandato con rappresentanza): the tax representative acts as a legal agent with explicitly defined powers, and cannot legally execute any act that falls outside that defined scope, regardless of how broad their general representational role may appear.

Signing the VIES bond is a specific act that requires specific authorization. Without it, the signature is technically valid in form but cannot produce the legal effects required for VIES registration purposes. Note that the Tax Authority has also rolled out a verification portal for fiscal representatives that adds another layer of compliance scrutiny on the representative side.

Mandatory validity requirements for the bond

The Italian Tax Authority will recognize a VIES bond as legally valid and capable of fulfilling the registration requirement only when three conditions are met simultaneously. The recent TAR Lazio decision 4986/2026 has confirmed the underlying €50,000 guarantee obligation, making strict compliance with these formal requirements even more critical.

What happens when documentation is missing

When the Italian Tax Authority identifies a VIES bond signed by a tax representative without proper authorization documentation, it follows a standard procedure: it issues a formal request for documentary evidence, demands proof that the tax representative received specific authorization to sign the bond, suspends VIES registration processing until complete documentation is submitted, and may reject the application entirely if proper documentation is not provided within the specified timeframe.

The correct power of attorney structure

If your company intends to authorize the tax representative to sign the VIES bond, the power of attorney must include specific language and elements. Generic language granting “general tax representation” or “authority to handle all tax matters” will not satisfy the Tax Authority — the document must explicitly reference the VIES bond.

Essential components of a compliant power of attorney

• Full legal identification of the authorizing company: name, registered office, foreign tax identification number
• Full identification of the tax representative: name, address, Italian tax code
• Explicit clause granting authority to sign, in the name and on behalf of the company, the guarantee bond (polizza fideiussoria) required for registration in the VIES database of intra-community operators
• Date of execution
• Signature of an authorized representative of the company (notarized signatures are strongly recommended)
• Duration and any scope limitations

Alternative path: direct signature by the foreign company

Not all non-resident companies want to delegate bond-signing authority to their Italian tax representative. A second legally valid approach exists: the foreign company can sign the bond directly, through its own legal representative. Under Italian law, the function of the bond signature is to perfect the contractual agreement — there is no statutory requirement that the tax representative must be the signatory. Direct signature by the foreign company is fully acceptable to the Tax Authority and avoids the complexity of additional power-of-attorney documentation.

How foreign companies can sign directly

A company based in Switzerland, the United Kingdom, or any other non-EU jurisdiction can sign the VIES bond directly using one of the following methods:

Italian Tax Authority requirements for direct signatures

• The signature must originate from the company’s legal representative or from someone holding a notarized power of attorney
• The signature method must ensure document authenticity and integrity — a qualified digital signature is the safest option
• If a qualified digital signature is not used, the document must be accompanied by an official certificate of authenticity (notarial certificate or government certification)
• The bond must clearly identify the signing company: name, registered office, foreign tax identification number
• The execution date must be clear and verifiable
• If documentation is in a language other than Italian, an official Italian translation should be attached to avoid additional documentation requests

The role of the tax representative remains essential

Even if your company opts for direct signature of the bond, your Italian tax representative continues to perform essential functions. Tax representation for ordinary Italian tax matters, VAT reporting, and other administrative obligations still requires a tax representative. Choosing direct bond signature does not eliminate the need for a tax representative — it simply handles a single document differently.

Immediate action steps

If your company is preparing to register for VIES, or has already received a Tax Authority request for power-of-attorney documentation, do not wait for a rejection notice. Companies that delay until rejection find themselves in a much weaker position, often facing resubmission with additional scrutiny.
