How to Be in a VAT Group in Italy (2026): Eligibility, Control Links, Modello AG/1 & Jan–sept Deadlines

Last updated: July 18, 2026

Understanding how to be in a VAT group is one of the most consequential compliance decisions a corporate group operating in Italy can make. Under Italian law, eligible businesses may elect to be treated as a single taxable person for VAT purposes, eliminating VAT on intra-group supplies, consolidating credits and debits, and filing a single periodic return. The mechanism is governed by D. P. R. 26 October 1972, n. 633 (Italy’s core VAT statute) and implements Article 11 of Council Directive 2006/112/EC (the EU VAT Directive).

Critically, the annual filing window for Modello AG/1, the declaration that creates, modifies or terminates a VAT group, runs from 1 January to 30 September, with the grouping taking effect on 1 January of the following calendar year. This guide walks CFOs, tax directors, in-house counsel and advisors through every step: eligibility tests, control-link calculations, filing procedures, representative-member obligations, and the practical traps to avoid.

Quick VAT Primer and Why Grouping Matters

Italy levies value added tax (imposta sul valore aggiunto, IVA) on the supply of goods and services within its territory, on intra-Community acquisitions and on imports. The standard rate is 22%, with reduced rates of 10%, 5% and 4% applying to specified categories. Every entity that independently carries out an economic activity must register for VAT, there is no registration threshold for non-resident businesses, while resident small businesses benefit from a flat-rate regime below certain turnover limits. How does the VAT tax work in Italy at a structural level? Each taxable person charges output VAT on sales, deducts input VAT on purchases, and remits the net balance to the Agenzia delle Entrate through periodic (monthly or quarterly) returns.

VAT grouping changes this dynamic fundamentally. When two or more persons form a VAT group under the vat grouping rules Italy has adopted, they cease to exist as separate taxable persons for VAT purposes. Instead, the group is treated as a single taxable person. Supplies between members are disregarded for VAT, and only transactions between the group and third parties generate VAT obligations. The representative member files a single consolidated return on behalf of all participants.

Key Consequences for Accounting and Cashflow

For groups with large volumes of intercompany transactions, management fees, shared services, licensing, goods transfers, VAT grouping can eliminate significant cashflow drag. Without grouping, one member charges VAT on an internal supply, the recipient claims a deduction, and both must account for the amounts in their respective returns. Even where the net effect is zero, the administrative burden and timing mismatches are real. Grouping removes these flows entirely: no invoicing obligation for intra-group supplies, no input-tax deduction to track, and consolidated net positions that reduce the overall compliance footprint. Industry observers expect the simplification benefit to be most pronounced for holding structures, financial-services groups and public-body conglomerates with exempt or partially exempt activities.

Who Can Join a VAT Group, Eligibility and Control Links

The vat group requirements Italy imposes are structured around three cumulative tests: a financial link (ownership or control), an economic link (aligned or complementary economic activities) and an organisational link (common governance or coordination structures). All three must be satisfied simultaneously. In addition, each prospective member must be established in Italy or have a fixed establishment there. Non-resident entities without an Italian fixed establishment cannot participate.

Participation is open to bodies corporate (companies limited by shares, limited-liability companies, cooperatives), partnerships, and, subject to conditions, other entities with legal personality such as foundations and public bodies. Natural persons carrying on an economic activity may also participate, although in practice the regime is most relevant to corporate groups.

Ownership and Control Tests, Numerical Examples

The financial link is typically demonstrated through direct or indirect ownership of more than 50% of the voting rights or share capital. Consider two worked scenarios:

• 100% subsidiary. Parent company Alfa S.p.A. wholly owns Beta S.r.l. and Gamma S.r.l. All three are established in Italy. The financial link is straightforward: Alfa controls both subsidiaries. If their activities are complementary (economic link) and they share a common board member or management structure (organisational link), all three are eligible to form a VAT group.
• 60/40 joint-control arrangement. Alfa S.p.A. holds 60% of Delta S.r.l., while an unrelated third party holds 40%. Alfa meets the majority-control threshold and can include Delta in a VAT group application. However, the third-party minority shareholder cannot itself join unless it independently satisfies the financial-link test with Alfa or another member.

Special Rules for Public Bodies and Investee Companies

Public bodies (enti pubblici) that carry out economic activities subject to VAT may in principle participate in a VAT group. The practical challenge lies in demonstrating the financial and organisational links. Where a municipality or public entity holds a majority stake in an investee company (società partecipata), the financial link is present, but the economic and organisational tests require careful documentation, particularly where the investee operates under public-procurement constraints or in-house-providing rules. The interaction between VAT grouping and the split-payment regime (discussed below) adds a further layer of complexity for public-body participants.

How to Be in a VAT Group: Modello AG/1 Timing, Content and Online Filing Steps

The Modello AG/1 is the official declaration through which a VAT group is created, modified (members added or removed) or terminated. According to the Agenzia delle Entrate, applications can be filed from 1 January to 30 September of any year, and the grouping takes effect from 1 January of the following year. This means that for Italy VAT groups registration effective 1 January 2027, the Modello AG/1 must be submitted no later than 30 September 2026.

The form is filed by the designated representative member (rappresentante del gruppo), typically the parent company or the entity with the broadest VAT activity. It must be submitted electronically through the Agenzia delle Entrate’s Entratel or Fisconline portal, either directly or through an authorised intermediary (intermediario abilitato).

What to Attach: Documents and Evidence

While the Modello AG/1 itself is a structured electronic form, the Agenzia delle Entrate may request supporting documentation to verify the three control links. Groups should prepare and retain the following:

• Up-to-date share registers and ownership charts for all prospective members
• Board resolutions from each member authorising participation in the VAT group
• Intercompany agreements evidencing economic and organisational integration
• Certificates of incorporation or fixed-establishment documentation for each member
• Signed declarations of intent from each member’s legal representative

How to Form a VAT Group in Italy Tax Online: Agenzia delle Entrate Portal

To file the Modello AG/1 online, the representative member (or its intermediary) logs in to the Agenzia delle Entrate portal, navigates to the “Servizi per” section and selects the VAT group declaration service. The form requires identification data for every member (VAT number, fiscal code, registered office), a description of the control links, and the designation of the representative member. Once completed and digitally signed, the declaration is transmitted electronically. The portal issues a receipt confirming submission, retain this as proof of timely filing.

Representative Member, VAT Number and Intra-Group Accounting

Once a VAT group is established, it receives a single VAT identification number. All external transactions, supplies to third-party customers, purchases from non-members, are invoiced under this group VAT number, with the representative member responsible for filing the consolidated periodic and annual VAT returns.

Intra-group supplies are disregarded for VAT purposes: no output VAT is charged, no input VAT is deducted, and no invoice is required for VAT purposes (although members may still need internal documentation for accounting, transfer-pricing or corporate-tax reasons). For external supplies, each member acts in the name of the group. The representative member collects data from all participants, consolidates output and input VAT, and files a single return.

Consider a simplified example: Member A sells consulting services to a third-party client for €100,000 plus 22% VAT (€22,000). Member B purchases raw materials from an external supplier for €50,000 plus 22% VAT (€11,000). The group’s net VAT liability for the period is €22,000 minus €11,000 = €11,000, which the representative member remits. Any internal supply from A to B is invisible for VAT.

Liability and Governance

The representative member bears primary responsibility for VAT compliance on behalf of the group. Under the provisions of D.P.R. n. 633/1972, all members of the group are jointly and severally liable for the VAT debts of the group. This joint-liability exposure is a critical governance consideration: a default by any member in providing accurate data can trigger penalties and interest for the entire group. Robust internal-governance protocols, data-sharing agreements, reconciliation procedures, and clear allocation of compliance tasks, are essential to manage this risk effectively.

Pros, Cons and Traps, VAT Group vs Split Payment and Other Alternatives

VAT grouping is not universally advantageous. Decision-makers should weigh the benefits against the constraints and consider whether Italy’s split-payment regime (scissione dei pagamenti) or remaining as separate taxable persons produces a better outcome.

The split-payment mechanism requires certain purchasers, primarily public administrations and listed companies, to pay VAT directly to the Treasury rather than to the supplier. Where a public body participates in a VAT group, the interaction between grouping and split payment can be complex: supplies from the group to external public administrations may still fall under split-payment rules, while intra-group supplies to the public-body member are disregarded. Early analysis is essential to avoid unexpected cashflow consequences.

Record-Keeping, Audits and Common Documentary Evidence Requested by Agenzia delle Entrate

The Agenzia delle Entrate may audit a VAT group to verify that the eligibility conditions continue to be met and that intra-group transactions are correctly excluded from VAT returns. Groups should maintain a comprehensive audit file, updated annually, containing at minimum the following:

• Ownership and control documentation. Current share registers, shareholder agreements, and corporate-governance charts demonstrating the financial link.
• Board resolutions. Minutes authorising initial participation and any subsequent changes to the group’s composition.
• Intercompany agreements. Contracts evidencing the economic link, service-level agreements, licensing arrangements, shared-services contracts.
• Management and organisational evidence. Documentation of common directors, shared management functions or coordination structures satisfying the organisational link.
• Intra-group transaction records. Although no VAT invoice is required, internal documentation of goods and service flows between members supports transfer-pricing compliance and corporate-tax reporting.
• Consolidated VAT returns and working papers. The representative member’s filed returns, reconciliation schedules and supporting calculations.
• Correspondence with Agenzia delle Entrate. All notices, queries and responses related to the VAT group, including the AG/1 filing receipt.

Step-by-Step Checklist and Timeline to Form a VAT Group in Italy

For groups targeting a 1 January 2027 effective date, the following action plan provides a practical roadmap. Each step should be assigned to a responsible person (typically the group tax director or external adviser) with a clear deadline.

1. January–March 2026: Assess eligibility, confirm financial, economic and organisational links for all prospective members. Identify the representative member.
2. April–May 2026: Gather supporting documentation, share registers, board resolutions, intercompany contracts and establishment certificates.
3. June 2026: Prepare the Modello AG/1, complete all required fields; obtain signed declarations of intent from each member’s legal representative.
4. July–August 2026: Internal review, legal and tax advisers review the form and supporting file for completeness and accuracy.
5. By 30 September 2026: Submit Modello AG/1 electronically via the Agenzia delle Entrate portal. Retain the electronic receipt.
6. October–December 2026: Prepare for operational transition, align accounting systems, update invoicing procedures, and establish internal data-sharing protocols for consolidated returns from 1 January 2027.

Conclusion

Forming a VAT group in Italy offers substantial compliance and cashflow benefits for corporate groups, holding structures, public bodies and their investee companies, but only if the eligibility conditions are met and the procedural steps are followed precisely. The single most important deadline is 30 September: file Modello AG/1 by that date for a grouping effective the following 1 January. Understanding how to be in a VAT group requires methodical preparation, from verifying control links and gathering documentation to aligning internal systems for consolidated reporting. For groups considering this step, engaging specialist tax advisers with experience in Italian VAT grouping is essential to navigate the eligibility tests, manage joint-liability risks and ensure a smooth transition.
