From co-ownership to a commercial company: the tax authorities accept the tax neutrality regime

Many farming businesses and family estates are still organised today as co-ownerships set up decades ago. The growth of the estate, the arrival of new generations and the geographical spread of the properties eventually reveal the limits of that legal form. Reorganisation by contributing the assets to a commercial company is the natural way out, and the Spanish Directorate General for Taxation has again ruled on its tax treatment in binding ruling V0770-26 of 7 April 2026.

The facts submitted

A co-ownership set up in 1990 farms several rural properties totalling more than 1,500 hectares. For the last two years it has kept accounts in accordance with the Spanish Commercial Code, recording the land at cost.

The co-owners are considering contributing that land, at book value, to a company resident in Spanish territory, so that after the transaction each of them holds at least 5% of its equity. The stated purpose is to bring the family estate together under a single legal entity, to prepare the succession and the generational handover through the transfer of shares rather than undivided interests in land spread across different provinces, and to modernise the management of the business.

Characterisation: contribution of shares in the co-ownership, not of a business unit

It should be made clear at the outset that there is no conversion in the company law sense. What takes place is the contribution by each co-owner of their undivided share.

For that reason the Directorate General for Taxation rules out the application of article 87.2 of the Corporate Income Tax Act, which deals with contributions of business units. None of the contributions taken individually has as its subject matter a set of assets constituting an autonomous economic unit, but rather an aliquot share of the ownership of assets held in undivided co-ownership.

The applicable route is article 87.1, which governs special contributions in kind made by personal income taxpayers. Each co-owner therefore makes their own contribution.

Requirements under article 87.1 of the Corporate Income Tax Act

For the transaction to qualify for the special regime in Chapter VII of Title VII of the Corporate Income Tax Act, three conditions must be met.

First, the entity receiving the contribution must be resident in Spanish territory or carry on activities there through a permanent establishment to which the contributed assets are allocated.

Second, after the contribution the contributor must hold at least 5% of the equity of the receiving entity. This requirement must be met individually by each co-owner, not jointly by the co-ownership.

Third, the contributed assets must be allocated to economic activities whose accounts are kept in accordance with the Commercial Code or equivalent legislation. In the case examined, that obligation falls on the co-ownership itself, which must carry on an economic activity and keep accounts in accordance with those rules.

The Directorate General for Taxation stresses that these circumstances are questions of fact to be proved by the applicant under articles 105 and 106 of the General Tax Act, and that their assessment will fall to the review bodies of the tax administration.

Valid economic reasons

Application of the neutrality regime also requires passing the filter in article 89.2 of the Corporate Income Tax Act, which excludes it where the principal purpose of the transaction is tax fraud or evasion.

The ruling sets out the settled doctrine on this clause. The Supreme Court, in judgments 2508/2016 of 23 November and 1503/2022 of 16 November, has held that the absence of valid economic reasons does not automatically preclude application of the regime but constitutes a presumption to be assessed, and that the tax advantage inherent in deferral is legitimate as part of the freedom to choose the least burdensome lawful arrangement, unless it becomes the very purpose of the transaction. The Court of Justice of the European Union, in its judgment of 8 March 2017 in Euro Park (C-14/16), had already rejected the use by Member States of general presumptions of fraud or predetermined criteria, requiring instead an overall examination of each transaction.

Given the reasons put forward, namely bringing the family estate together, preparing the succession, planning the generational handover and modernising management, the Directorate General for Taxation concludes that the transaction may qualify for the tax neutrality regime.

What this ruling actually means

The ruling reads as a favourable answer, but it is worth noting how it is constructed.

The authorities do not verify facts, they assume them on the basis of what the applicant states. Both the allocation of the assets to an economic activity and the keeping of accounts in accordance with the Commercial Code are expressly left to proof and to a possible subsequent review. In a co-ownership that has farmed land since 1990 and has kept Commercial Code accounts for only two financial years, that is precisely where any review will begin.

There is also a practical consequence flowing from the characterisation of the transaction: since there is no business unit, there is no contribution by the co-ownership but as many contributions as there are co-owners. The 5% threshold is tested one by one and the transaction documents must reflect that.

Conclusion

Reorganising a co-ownership by contributing it to a commercial company is an accepted transaction and, in large family estates, frequently advisable. The tax neutrality regime allows it to be carried out without an immediate tax cost, provided the legal requirements are met.

That regime is not obtained, however, merely by invoking it in the deed. It is sustained by accounts, records and genuine economic activity capable of showing, if the authorities review the matter, that the requirements were met on the day of the contribution. Preparing that documentation before executing the transaction, and not afterwards, is what makes the difference.

Where the reorganisation is undertaken with the succession in mind, it should be analysed alongside the other testamentary decisions, among them the bequest of assets in favour of the company itself, whose tax cost follows different rules.
