Dissolution of co-ownership: stamp duty or transfer tax

The dissolution of a co-ownership over real estate is one of the transactions that most frequently ends in a supplementary tax assessment. The difference in cost between one treatment and another is substantial, and it does not depend on the intention of the parties but on how the allotment is structured. Binding ruling V0623-25, issued on 3 April 2025 by the Spanish Directorate General for Taxation, sets out the complete framework and is particularly useful as a reference.

The facts examined

A married couple holds, within their community of acquisitions, a 25 per cent interest in a dwelling, a storage room and two parking spaces. The applicant additionally holds 8.33 per cent as separate property, and each of his two siblings holds 33.33 per cent. The dwelling, the storage room and one of the parking spaces share a single cadastral reference; the second parking space has its own.

The proposed transaction consists of contributing the separate interest to the community of acquisitions and subsequently dissolving the co-ownership with the siblings, allotting the properties to that community.

The starting point: dissolution is not a transfer

The termination of a co-ownership with an allotment to each co-owner in proportion to their share does not amount to a genuine transfer, but to the specification or crystallisation of a pre-existing abstract right. This follows from article 450 of the Spanish Civil Code and has been consistently confirmed by the Supreme Court, among others in its judgment of 28 June 1999.

Hence the rule in article 61 of the Regulations on transfer tax and stamp duty: the dissolution of co-ownerships that have not carried on business activities, provided that the allotments are duly proportionate to the ownership shares, is taxed only, where applicable, under stamp duty.

The relevant question is therefore whether what each co-owner receives corresponds to their share. Three scenarios follow from the answer.

First scenario: no excess allotment

There is no transfer of assets and, accordingly, no charge to transfer tax. It is precisely that absence of charge which allows the deed to be subject to the variable stamp duty rate on notarial documents, provided that the four requirements of article 31.2 of the consolidated text are met: first authorised copy of a public deed, quantifiable subject matter, registrable act, and no charge to inheritance and gift tax or to the transfer tax or corporate transactions heads.

Second scenario: uncompensated excess allotment

If a co-owner receives more than their share and no compensation is paid, the transaction embodies a gratuitous transfer. The excess is taxed under inheritance and gift tax, pursuant to article 3.b) of Law 29/1987, as an acquisition by gift.

Third scenario: compensated excess allotment

Where the excess is compensated, the general rule in article 7.2.B) of the consolidated text characterises it as a transfer for consideration, taxable as such and payable by the recipient.

There is, however, a special rule of considerable practical importance. If the excess arises through the application of article 1062 of the Spanish Civil Code, that is, because the jointly owned asset is indivisible or would be substantially impaired by division, and it is allotted to one of the co-owners subject to the obligation to pay the others the excess, it is not treated as a transfer for consideration. The transaction is then subject to the variable stamp duty rate on notarial documents instead.

The application of this rule requires three cumulative conditions: indivisibility of the asset or substantial impairment on division, allotment to a single co-owner, and effective compensation of the co-owner who receives less.

As to the form of that compensation, the Supreme Court, in judgment 1502/2019 of 30 October, accepts that it need not be confined to cash: the assumption of the outstanding mortgage debt and the transfer of other assets in payment equally perform the balancing function required by the provision. Where several co-ownerships exist between the same co-owners, their simultaneous dissolution with allotment of the assets to one of them, or through the formation of lots that are as equivalent as possible, also falls within the scope of the exclusion.

The ruling notes that this approach represents a change of position compared with earlier answers issued by the same authority, prompted by the Supreme Court doctrine established in judgment 1058/2019 of 26 March.

How many co-ownerships exist

This is the point that most often determines the outcome and the one that usually receives least attention.

If several co-ownerships exist over the assets, there will be as many legal transactions as there are co-ownerships, and each must be dissolved independently, with equivalent lots within each of them. In the case examined, the Directorate General for Taxation identifies two: the one comprising the dwelling, the storage room and the parking space sharing a cadastral reference, and the one comprising the separate parking space.

The consequence is decisive. If the co-owners exchange properties belonging to different co-ownerships, the transaction ceases to be a dissolution and is characterised as a barter, with the resulting charge to transfer tax, under the characterisation principle in article 2 of the consolidated text.

It is worth stressing that the tax authorities themselves acknowledge that determining whether one or several co-ownerships exist is a question of fact on which they cannot rule definitively, and which will fall to be assessed by the tax management and inspection bodies.

The taxable base

The Supreme Court, in settled case law comprising judgments 1484/2018, 344/2019, 1317/2019 and 1379/2019, has held that the value documented in the dissolution of a co-ownership is not that of the entire asset, but only that of the portion acquired anew, which is what the deed covers and where the taxpaying capacity is manifested.

This does not exclude the application of the rules for determining the taxable base in articles 10 and 30 of the consolidated text, including the reference to the cadastral reference value where appropriate.

Conclusion

The dissolution of co-ownership admits three very different treatments and the line between them is a fine one. Identifying the co-ownerships that actually exist, ensuring the lots are equivalent and making the compensation effective are decisions taken before attending the notary, because once the deed has been signed there is virtually no scope for correction.

Before dissolving a co-ownership it is worth reviewing how many co-ownerships there really are, whether the assets allow an alternative distribution that avoids or reduces the excess, how the compensation is documented and what value is stated. The same requirement of advance planning applies to other transactions involving family assets, such as a succession agreement in the Balearic Islands or the purchase of property by someone resident outside Spain.
