The new VAT taxable base for barter transactions from 2026: what changes

From January 1, 2026, the rules for determining the VAT taxable base in barter transactions will officially change. The update was introduced by the 2026 Budget Law (Law No. 199/2025) with the aim of aligning Italian legislation with European regulations and overcoming certain interpretative issues that have generated application doubts over the years.

The reform modifies one of the most sensitive aspects of barter transactions: the criterion used to determine the value on which the tax is calculated.

VAT taxable base in barter transactions: the regime until 2025

Until December 31, 2025, in barter transactions, the VAT taxable base is determined by referring to the open market value of the goods or services being exchanged. According to Art. 14 of Presidential Decree 633/1972, the open market value corresponds to the average price charged for similar goods or services under conditions of free competition and at the same stage of commercialization.

Furthermore, Art. 11 of the same decree establishes that, in barter transactions, each supply of goods or services must be considered independently for VAT purposes. This means that each transaction is subject to tax based on the open market value of the exchanged good or service.

Misalignment with European regulations

This mechanism, applied generally to barter transactions, is not perfectly consistent with the provisions of VAT Directive 2006/112/EC. In fact, European regulations allow recourse to the open market value only in specific cases, particularly when transactions occur between parties linked by special relationships (corporate, family, or financial) and there is a risk of altering the taxable base.

The Court of Justice of the European Union has also clarified that the use of the open market value cannot be applied generally to exchange transactions. For this very reason, the European Commission initiated a dialogue with Italy within the framework of the EU Pilot procedure 2022/10314, requesting the alignment of national legislation.

The new VAT taxable base for barter transactions from 2026: the reform

To overcome this issue, the 2026 Budget Law intervenes by directly amending Art. 13 of Presidential Decree 633/1972. From January 1, 2026, the new VAT taxable base for barter transactions will be determined:

Based on the value of the goods or services involved in the transaction, calculated on the basis of the total amount of costs incurred to carry out the supply or service.

In essence, the reference for calculating the tax will no longer be the market value of the exchanged item, but the total cost attributable to the transaction itself.

Operational impacts for businesses and professionals

The new regulations will require greater attention to the reconstruction and documentation of costs related to exchange transactions. For businesses that frequently use barter—for example, in commercial relationships or services exchanged between economic operators—it will therefore become essential to:

• Correctly identify the costs attributable to the individual transaction.

• Maintain clear, analytical, and traceable accounting documentation.

• Verify the impact of the new regulations on the determination of the VAT actually due.

The amendment therefore represents an important step towards greater consistency between Italian legislation and European law, with practical effects that businesses and professionals must consider starting from 2026.

MEF clarification on the effective date of contracts

In this regard, it is noted that the MEF, in its press release dated 2026-03-12, has announced a forthcoming legislative measure that will intervene in the 2026 Budget Law.

Specifically regarding barter transactions, the Ministry will clarify that the new criterion (which adopts the total amount of costs as the VAT taxable base for barter transactions and transfers in lieu of payment) applies exclusively to transactions carried out in execution of contracts entered into or renewed from January 1, 2026.

Consequently, for contracts entered into before January 1, 2026, the old open market value criterion will continue to apply. This solution, in compliance with the principle of legitimate expectation and legal certainty, allows for the preservation of contractual arrangements already established under the previous regulations.
