IMT Jovem and Undivided Inheritances: Does inheriting a house prevent the tax exemption?

Inheriting a property might seem like a clear-cut reason to lose the "IMT Jovem" tax benefit—but that is not always the case. The Portuguese Tax Authority (AT) has clarified when it is possible to maintain the exemption, revealing a decisive factor: the moment the inheritance is partitioned.

The implementation of the IMT Jovem regime brought a significant incentive for the onerous acquisition of a first home by young people up to the age of 35. However, a practical doubt quickly arose that continues to lead to incorrect—and potentially very expensive—decisions: what happens when the young person is already an heir to a property?

The intuitive response for many taxpayers—and even some professionals—has been immediate: if you inherited a house, you are already an owner and have lost the benefit. But this conclusion is not only simplistic; it can be legally wrong.

Binding information from the Tax Authority has clarified this issue—and the understanding is more favorable than one might suppose.

The Distinction Between Heir and Owner The core issue lies in the distinction between being an heir and being an owner. In Portuguese law, as long as an inheritance has not been partitioned (partilha), we are dealing with an undivided inheritance (herança indivisa). This is an autonomous patrimony belonging to the collective group of heirs. At this stage, none of them is the owner of specific assets; there is only a right to an "ideal share" of the inheritance as a whole.

This distinction, which may seem purely theoretical, has very significant practical consequences.

According to the Tax Authority, as long as the inheritance remains undivided, the heir cannot be considered the owner of a specific property. Consequently, the cause for exclusion from the IMT Jovem regime does not, by itself, apply.

To put it clearly: inheriting a house does not automatically mean losing the right to the IMT exemption.

The Decisive Factor: The Timing of the Partition However, there is a detail that makes all the difference—and which can determine the loss or maintenance of the benefit: the moment of the partition.

1. Before Partition: If, at the time of acquiring the new home, the inheritance has not yet been partitioned, the taxpayer is still not considered the owner of specific assets. In this scenario, they can benefit from IMT Jovem, provided they meet the other legal requirements.

2. After Partition: On the other hand, if the partition has already occurred and the heir has become the owner (or even a co-owner) of at least one urban residential building, they are automatically excluded from the benefit.

In practice, carrying out partitions before purchasing a home can mean losing an exemption worth thousands of euros. Most critically, this consequence often results from decisions made without proper legal guidance.

A Case-by-Case Analysis It is important to emphasize that not all situations are linear. The number of heirs, the existence of a sole heir at the relevant time, or changes in the composition of the inheritance can influence the tax framework. The analysis must always be case-specific.

This topic demonstrates that the intersection between succession law and taxation requires a technical approach. Intuitive solutions—such as proceeding with partitions without assessing the tax impact—can translate into significant and unnecessary costs.

Conclusion In light of the Tax Authority's understanding, the heir of an undivided inheritance that holds at least one residential property is not considered the owner of a residential property for the purposes of IMT Jovem.

Before buying a house, and especially when there are inheritances involved, you must analyze the issue. In this field, the difference between paying or not paying tax can depend on a legal detail that is not obvious at first glance.

VPA – Sociedade de Advogados and its team are available to provide legal advice on this matter, specifically in analyzing the framework of undivided inheritances regarding IMT Jovem and verifying the legal requirements for accessing the benefit. A case-by-case assessment of each situation, particularly regarding the timing of the partition and the structure of the inheritance, will identify the most legally appropriate and tax-efficient solution.
