Share contributions:
Article 177 TUIR and the 2026 framework

A shareholder who wishes to reorganise a corporate structure may contribute shares or quotas held in an operating company to another company, often a newly incorporated holding company, receiving shares or quotas in the receiving company in return.

From a tax perspective, these transactions require particular attention because the ordinary rules governing contributions may result in the recognition of taxable gains. Article 177 TUIR provides a specific regime for qualifying transactions, commonly referred to as the controlled realisation regime.

What is the controlled realisation regime?

Under the conditions established by Article 177 TUIR, the tax value realised by the contributor is determined by reference to the corresponding equity amount recorded by the receiving company as a consequence of the contribution.

The regime is therefore not a general exemption from taxation. Instead, it introduces a specific criterion for determining the value realised by the contributor.

Contributions that give the receiving company control

Article 177 provides specific rules where, as a result of the contribution, the receiving company acquires control of the company whose shares are contributed, or increases an existing controlling interest.

Control must be assessed according to the relevant corporate law rules and the specific circumstances of the transaction. Therefore, the ownership structure before and after the contribution should always be examined carefully.

Contributions of qualifying minority interests

The regime may also apply in certain cases where the receiving company does not acquire control. Article 177, paragraph 2-bis, extends the controlled realisation mechanism to contributions of qualifying interests when the statutory requirements are satisfied.

In these situations, the percentage of voting rights and the percentage of capital or equity represented by the contributed interest become particularly important. Different thresholds apply depending on whether the shares are traded on regulated markets.

The receiving company and the shareholder structure

For transactions falling within paragraph 2-bis, the characteristics of the receiving company and its shareholder structure must also be considered.

The legislation allows the receiving company to be either an existing or newly incorporated company, subject to the requirements established by the applicable provisions.

Share contributions and holding companies

One of the most common applications of Article 177 is the creation or reorganisation of a holding structure.

A shareholder may contribute an interest held in an operating company to a holding company in exchange for an interest in the holding itself. This can allow ownership to be reorganised at a higher level while the operating company continues its business activity.

The tax regime should not, however, be the sole reason for creating a holding company. Governance, asset allocation, dividend flows, future investments, business succession and potential disposals should all be considered as part of the overall structure.

The 2026 developments

The rules governing share contributions have been subject to significant legislative intervention in recent years and were further revised in 2026.

The 2026 corrective tax legislation further refined the framework applicable to contributions, making it particularly important to verify the legislation in force at the date on which a transaction is implemented.

Values below the tax basis

Particular attention is required where the value determined under the controlled realisation mechanism is lower than the contributor's tax basis in the contributed interest.

The legislation specifically regulates these situations and the possible recognition of a tax loss. The normal value of the contributed interest may also become relevant when determining the amount of any deductible loss.

Contributions as part of a wider reorganisation

A share contribution is frequently only one step within a wider corporate reorganisation.

It may precede a generational transition, the creation of a family holding company, the entry of new investors, a corporate acquisition or disposal, or a broader reorganisation of the group.

For this reason, the transaction should be analysed not only from the perspective of Article 177, but also in light of its corporate purpose, governance implications and subsequent transactions.
