Process: 477/2014-T

Tax Type: Selo

Source: Original CAAD Decision

Summary

In CAAD arbitration process 477/2014-T, a Portuguese company successfully challenged a Stamp Tax (Imposto do Selo) assessment of €38,495.08 imposed on construction land under Verba 28.1 of the General Stamp Tax Table (TGIS). The dispute centered on whether construction land (terrenos para construção) qualifies as 'property with residential purpose' subject to the 1% annual stamp duty introduced by Law 55-A/2012 on properties valued at €1,000,000 or more.

The claimant owned an urban property in Porto classified as a construction site with a tax asset value of €3,849,508.23. The Tax Authority (AT) assessed stamp duty for 2013 under item 28.1 GTSD, which specifically targets 'property with residential purpose' (prédio com afetação habitacional). The property owner argued that construction land constitutes a legally distinct category from residential property and cannot be equated with it for tax purposes. They contended that the assessment violated both statutory law (Article 1 of the Stamp Tax Code and item 28.1 GTSD) and constitutional principles (Articles 13, 81, 103(3), and 104 of the Portuguese Constitution).

The Tax Authority maintained that construction sites should be treated as equivalent to residential properties for purposes of applying item 28.1. However, the arbitral tribunal identified a critical legal gap: the term 'property with residential purpose' represented an innovative concept not defined in any other Portuguese tax legislation, including the Municipal Property Tax Code (CIMI). The tribunal emphasized that tax law requires strict interpretation and cannot be extended beyond its express terms. Construction sites, being undeveloped land intended for future construction, lack the essential characteristic of actual residential use or purpose. The tribunal ruled that item 28.1 GTSD does not permit extensive interpretation to include construction land within its scope, finding the assessment illegal and ordering its annulment. This decision established important precedent that stamp duty under Verba 28.1 applies exclusively to existing residential properties, not vacant construction land.

Arbitral Decision

I. STATEMENT OF FACTS

A… – …, LDA, with registered office in … Porto, holder of the single registration number and legal entity identification number …, hereinafter simply designated as Claimant, filed a request for constitution of an arbitral tribunal in tax matters and a request for arbitral award, pursuant to the provisions of articles 2º no. 1 a) and 10º no. 1 a), both of Decree-Law no. 10/2011, of 20 January (Legal Framework for Arbitration in Tax Matters, abbreviated as LFRM), petitioning for the annulment of the tax act of assessment of Stamp Duty (SD) for the year 2013, in the total amount of € 38,495.08.

To substantiate its request, it alleges, in summary:

a) The Claimant is the owner of the urban property located at …, parish of Y…, Porto, registered in article … of the respective urban property register;

b) The Claimant was notified to make payment of the first and second instalments of the Stamp Duty assessment, referring to the year 2013, in the amounts of, respectively, € 12,831.70 and € 12,831.69;

c) Such assessment was made under item 28.1 of the General Table of Stamp Duty (GTSD);

d) The property subject to the stamp duty assessment in question is a construction site;

e) In the version given by Law no. 55-A/2012, of 29 October, in force on 31.12.2013, item 28.1 of the (GTSD) only provided for the taxation of properties with residential purpose, with no taxation being provided for construction sites;

f) Construction sites constitute a species of property completely distinct from properties classified as residential;

g) Neither the letter nor the spirit of the law permit the equation of construction sites with properties with residential purpose, for the purposes of their taxation by application of item 28.1 of the GTSD attached to the STC;

h) The classification of construction sites as "properties with residential purpose" for the purposes of their subsumption to SD, by application of item 28.1 of the GTSD, attached to the STC, in the version given by Law no. 55-A/2012, of 29 October, is illegal;

i) The assessment in question is illegal, for violation of the provisions of article 1 of the STC and of item 28.1 of the GTSD and unconstitutional, for violation of articles 13, 81, and no. 3 of articles 103 and 104 of the Constitution of the Portuguese Republic.

The Claimant attached four (4) documents and listed one witness.

In the request for arbitral award, the Claimant chose not to appoint an arbitrator, whereby, pursuant to the provisions of article 6º no. 1 of the LFRM, the signatory was appointed by the Deontological Council of the Administrative Arbitration Centre, with the appointment having been accepted in accordance with legal provisions.

The arbitral tribunal was constituted on 16 September 2014.

Notified in accordance with and for the purposes of the provisions of article 17º of the LFRM, the Respondent presented a response, invoking in summary that, for purposes of application of item 28.1 of the GTSD attached to SD, construction sites are equivalent to properties with residential purpose.

It concludes petitioning for the dismissal of the request and, consequently, the maintenance of the assessment acts at issue.

The Respondent did not attach a copy of the administrative file and did not list any witness.

Given the position assumed by the parties and there being no need for additional production of evidence, the questioning of the witness listed by the Claimant was dispensed with, and a waiver of the meeting referred to in article 18º of the LFRM and the presentation of arguments was also determined.

II. QUESTIONS TO BE DECIDED:

In the present case, the question to be decided consists solely in determining whether, for purposes of application of item 28.1 of the GTSD attached to the STC, in the version given by Law no. 55-A/2012, of 29 October, a construction site is considered as a property with residential purpose.

c. Substantiation of the Factual Matters:

The conviction regarding the facts given as proven was based on the documentary evidence submitted by the Claimant, indicated in relation to each of the points, whose authenticity and adherence to reality was not disputed by the Respondent.

IV. PLEAS IN ABATEMENT:

The Arbitral Tribunal is regularly constituted and is materially competent.

The parties enjoy legal capacity and legal standing, are legitimate and are properly represented.

The proceedings do not suffer from defects affecting their validity, with no exceptions or preliminary questions that prevent the judgment on the merits and of which it is necessary to take official cognizance.

V. ON THE LAW:

The factual matter being fixed, it is now necessary, with reference to it, to ascertain the applicable law.

The Claimant argues that construction sites cannot be considered, for purposes of subjection to SD, as properties with residential purpose.

In its understanding, the provision of item 28.1 of the GTSD attached to the STC does not allow for any extensive interpretation, so that construction sites can be equated with properties with residential purpose, with the indicated item 28.1 therefore not being applicable to them.

To the contrary, the Respondent argues that the property on which the impugned assessment falls has the legal nature of a property with residential purpose, not suffering from any illegality or unconstitutionality.

As to objective incidence, article 1, no. 1 of the STC provides that stamp duty is levied on all acts, contracts, documents, titles, papers and other facts or legal situations provided for in the General Table.

Article 4 of Law no. 55-A/2012, of 29 October added to the GTSD, attached to the STC, approved by Law no. 150/99, of 11 September, item no. 28, with the following wording:

"28 - Ownership, usufruct or right of superficies of urban properties whose tax asset value as shown in the register, pursuant to the Code of Municipal Property Tax (CMPT), is equal to or greater than € 1,000,000 - based on the tax asset value used for purposes of CMPT:

28.1 - For property with residential purpose - 1%;

28.2 - For property, when the taxpayers who are not natural persons are resident in a country, territory or region subject to a clearly more favourable tax regime, listed in the list approved by order of the Minister of Finance - 7.5%."

That said,

In item 28.1 of the GTSD added by Law no. 55-A/2012, of 29 October, an innovative concept was used, which is not used by any other tax legislation: the concept of property with residential purpose.

Neither in the CMPT, indicated by the aforementioned Law no. 55-A/2012 as the subsidiary applicable statute with respect to the tax introduced by the addition of item 28 to the GTSD, is any such defined concept used.

In fact, the CMPT defines the concept of property, defines the various types of properties and identifies the species of urban properties.

Thus,

Pursuant to article 2 of the CMPT, "property is any fraction of territory, encompassing the waters, plantations, buildings and constructions of any nature incorporated in or resting on it, with a character of permanence, provided that it forms part of the assets of a natural or legal person and, under normal circumstances, has economic value."

Properties are divided into rural (article 3), urban (article 4) or mixed (article 5), with urban properties subdividing into 4 species: residential, commercial, industrial or for services; construction sites and others (article 6).

No. 3 of article 6 of the CMPT clarifies that construction sites are considered to be "lands situated within or outside an urban agglomeration, for which a licence or authorization has been granted, admitted prior notification or issued favourable prior information for a subdivision or construction operation, and also those that have been so declared in the acquisition title."

Combining the aforementioned provisions, it appears that there is no reference to property with residential purpose in any of the indicated rules.

Therefore, in order to determine what a property with residential purpose is, an exercise of interpretation must be carried out, resorting to the general rules of legal hermeneutics contained in article 9 of the Civil Code.

Thus, interpretive activity will have to begin with the analysis of the letter of the law, which constitutes the limit of interpretation, and an interpretation cannot be considered that does not have in the letter of the law a minimum of verbal correspondence, even if imperfectly expressed.

Now, as results from the legal provisions already cited, the concept of property with residential purpose is absolutely innovative in the STC, not existing in any other tax law.

The closest concept is that of "residential property", defined in no. 2 of article 6 of the CMPT as the building or construction licensed for such purpose or, in the absence of a licence, that has as its normal destination this purpose.

The truth, however, is that the legislator, in item 28.1 of the GTSD attached to the STC did not use the expression "residential property" but rather "property with residential purpose".

Therefore, proceeding from the principle – which is held as certain – that the legislator knew how to express itself in adequate terms, it cannot be maintained that these distinct expressions have the same meaning. Instead, and by way of application of the principles enshrined in nos. 2 and 3 of article 9 of the Civil Code, it must necessarily be maintained that, by using distinct expressions, the legislator intended to encompass different realities.

Let us focus, therefore, on the word "purpose", the noun form of the verb "to purpose".

This concept has already been exhaustively analysed by diverse and learned jurisprudence delivered by this arbitral centre[1], so we will refrain from dissecting such concept, accepting and maintaining that it consists in the action of destining something to a specific use.

Thus, property with "residential purpose" will be that which is destined for housing.

Indeed, the same conclusion is reached also through the reconstruction of legislative intent, taking into account the unity of the legal system, the circumstances in which the law was drafted and the specific conditions of the time in which it is applied, as mandated by the aforementioned article 9 of the Civil Code.

First and foremost, it is important to take into account that the introduction of this item 28 in the GTSD occurred at a time when, given the absolute necessity of dealing with the installed crisis, it was necessary to collect the maximum possible revenue, which was intended to be achieved, in particular, through the taxation of so-called "luxury" real properties.

It was intended, therefore, with the introduction of the taxation provided for in item 28 of the GTSD, to tax wealth, externalized in the ownership, usufruct or right of superficies of "luxury" urban properties with residential purpose.

That only properties with residential purpose are included in this new taxation results expressly from the Statement of Reasons of Bill no. 96/XII, in which it is stated that, with a view to strengthening the "principle of social equity in austerity, ensuring an effective distribution of the sacrifices necessary to comply with the adjustment programme", the legal diploma to be approved "extends the taxation of capital income and property, encompassing equitably a broad set of sectors of Portuguese society".

Thus, it can also be read in the aforementioned Statement of Reasons that "a rate is created under Stamp Duty levied on urban properties of residential purpose whose tax asset value is equal to or greater than one million euros" (emphasis ours).

Already within the scope of the discussion in general of the aforementioned Bill, it can be read:

"First, the Government proposes the creation of a special rate to tax urban residential properties of higher value. It is the first time in Portugal that a special taxation on high-value properties intended for housing is created. This rate will be 0.5% to 0.8%, in 2012, and 1% in 2013, and will apply to houses with a value equal to or greater than 1 million euros" (emphasis ours).

There is no doubt, therefore, that the legislator's intention was to tax houses, urban residential properties, properties intended for housing, that is, properties that are already actually destined for residential purpose.

Having established that the concept of "property with residential purpose" is as property actually destined for, devoted to housing, it is now important to analyse the actual scope of such concept. In other words, it is necessary to verify whether such residential purpose, for purposes of application of the provisions in item 28.1 of the GTSD, must be present or may be future, that is, whether it will encompass only properties that are already actually devoted to housing or also properties that, as is the case of the property in this case, being a construction site, do not yet have any defined purpose.

The distinction assumes special significance if we consider that a construction site may be destined to build, in the future, one or more residences, whereby, if future purposes that may be given to the property are included in the concept of "residential purpose", it could, in this case, be argued that item 28.1 of the GTSD applies to construction sites.

This understanding, however, has no adherence, in our view, to the letter and spirit of the law.

In fact, when analysing the literal tenor of item 28.1 of the GTSD it seems manifest that its application to properties whose purpose is unknown must be ruled out, as these, manifestly and from any point of view, cannot be considered destined for residential purpose.

For, not being known the purpose of the property in question, this may be destined for housing, as well as for commerce, industry or services, and it is certain that item 28.1 will only be applicable to properties with residential purpose and not to properties with any other purpose, in particular economic.

In the case at hand, having analysed the proven facts, it appears that the property in question does not yet have any known purpose, whereby it is manifest that item 28.1 of the GTSD should not be applied.

But even if the property in this case already had a known purpose, although not actual, and that purpose were residential, it would not be encompassed by the application of item 28.1 of the GTSD.

This is because, from the combination of the rules contained in item 28.1 of the GTSD and in no. 3 of article 6 of the CMPT, it results, without any margin for doubt, that the purpose must be actual and not merely future or probable.

In sum, a construction site whose purpose is unknown, as is the case of the property in this case, cannot be considered as a property with residential purpose for purposes of application of item 28.1 of the GTSD attached to the STC.

Neither should it be said, as the Respondent does, that the legal identity, for purposes of application of item 28.1 of the GTSD, between construction sites and properties with residential purpose results clearly from the fact that the legislator determines the application to construction sites of the valuation methodology for properties in general.

It is true that article 45 of the CMPT determines the application to construction sites of the same valuation methods applicable to properties in general.

However, it cannot be overlooked that such identity is limited to the valuation methodology and not to their classification.

With regard to valuation, there is no doubt that the legislator mandates the application of the same rules both to construction sites and to residential properties.

But as regards the classification of the property, nothing in the law or in general legislative intent permits us to conclude the existence of such identity.

In fact, as we believe is well stated in a judgment delivered by the Supreme Court of Justice, "it would be strange, besides, if the determination of the scope of the rule of tax incidence of item no. 28 of the General Table of Stamp Duty were found, after all, in the rules for determining the tax asset value of the CMPT Code, and that the terminological imprecision of the legislator in the drafting of that rule were, ultimately, elucidated and finally clarified by means of an indirect and equivocal reference to the purpose coefficient established by the legislator in relation to built properties (article 41 of the CMPT Code)[2].

Therefore, and following closely jurisprudence already established by this arbitral centre[3], it is to be concluded that "the available interpretive elements, including the 'circumstances in which the law was drafted and the specific conditions of the time in which it is applied', clearly point to the fact that it was not intended to encompass within the scope of incidence of item 28.1 situations of properties that are not yet devoted to housing, in particular construction sites held by companies", as is the case in this case.

But not only has the jurisprudence of this arbitral tribunal pronounced itself in this sense. In judgments delivered very recently, the Supreme Administrative Court decided that "since the legislator did not define the concept of 'properties (urban) with residential purpose', and as a result of article 6 of the CMPT Code – subsidiarily applicable to the Stamp Duty provided for in the new item no. 28 of the General Table – there is a clear distinction between 'urban residential properties' and 'construction sites', these cannot be considered, for purposes of incidence of Stamp Duty (Item 28.1 of the GTSD, in the version of Law no. 55-A/2012, of 29 October), as urban properties with residential purpose[4].

And that this is so results clearly from the fact that, in the last amendment made to item 28.1 of the GTSD attached to the STC, by Law no. 83-C/2013, of 31 December, which approved the State Budget for 2014, construction sites were here expressly included. Note, however, that even with this amendment, not all construction sites are subject to taxation by the application of item 28.1 of the GTSD attached to the STC, but only and exclusively construction sites whose building, authorized or planned, is for housing.

Since the aforementioned State Budget 2014 is not any interpretative law, it seems evident that, if the legislator felt the need to include in this item 28.1 the construction sites, it is because previously such sites were not included in the same, especially since such sites, as is the case of the land in this case, do not yet have any defined purpose, and it is unknown whether they will or will not be devoted to housing.

Any other interpretation of item 28.1 of the GTSD attached to the STC, in the version given by Law no. 55-A/2012, of 29 October, has no minimal legal support and cannot be defended.

It is thus verified that the assessment at issue in the present case is clearly illegal, as it has no legal foundation or sustenance.

Thus, as construction sites are not contained in item 28.1 of the GTSD attached to the STC, in the version given by Law no. 55-A/2012, of 29 October, and as these cannot be classified, for this purpose, as properties with residential purpose, it seems evident that these cannot be the object of taxation under this item.

Therefore, as there is no legal foundation for the assessment act carried out, its annulment tout court is necessary.

VI. OPERATIVE PART:

In light of the foregoing, it is decided to rule in favour of the request for declaration of illegality of the Stamp Duty assessment act in the total amount of € 38,495.08, with the consequent annulment of the same and of the payment instructions issued.


The value of the case is fixed at € 38,495.08, pursuant to item a) of no. 1 of article 97-A of the Tax Procedure and Process Code, applicable by virtue of items a) and b) of no. 1 of article 29 of the LFRM and of no. 2 of article 3 of the Regulation of Costs in Tax Arbitration Proceedings.


The value of the arbitration fee is fixed at € 1,836.00, pursuant to Table I of the Regulation of Costs of Tax Arbitration Proceedings, as well as the provisions of no. 2 of article 12 and of no. 4 of article 22, both of the LFRM, and of no. 4 of article 4 of the aforementioned Regulation, to be paid by the Respondent as the unsuccessful party.

Frequently Asked Questions

Automatically Created

Does Verba 28.1 of the Portuguese General Stamp Tax Table apply to construction land (terrenos para construção)?
No, Verba 28.1 of the Portuguese General Stamp Tax Table does not apply to construction land (terrenos para construção). CAAD arbitration process 477/2014-T established that item 28.1, introduced by Law 55-A/2012, specifically targets 'property with residential purpose' (prédio com afetação habitacional). Construction land represents a legally distinct category of urban property that lacks residential purpose or use. The tribunal ruled that tax law requires strict interpretation without extensive application, and construction sites cannot be equated with residential properties merely because they may potentially be developed for housing in the future. Only properties actually designated and used for residential purposes fall within the scope of Verba 28.1 GTSD.
Can construction land be classified as residential property for Stamp Tax purposes under Portuguese law?
No, construction land cannot be classified as residential property for Stamp Tax purposes under Portuguese law. In process 477/2014-T, the CAAD arbitral tribunal rejected the Tax Authority's argument that construction sites are equivalent to residential properties under item 28.1 GTSD. The tribunal noted that 'property with residential purpose' is an innovative concept not defined in other Portuguese tax codes, including the Municipal Property Tax Code (CIMI). Construction land (terrenos para construção) constitutes a distinct species of urban property under Portuguese property classification systems. Without actual residential use, allocation, or characteristics, vacant construction land cannot be subsumed within the definition of residential property for stamp duty purposes. The principle of strict interpretation in tax law prohibits extending Verba 28.1 beyond its express scope.
What was the outcome of CAAD arbitration process 477/2014-T regarding Stamp Tax on construction land?
The CAAD arbitral tribunal ruled in favor of the taxpayer in process 477/2014-T, annulling the Stamp Tax assessment on construction land. The tribunal found that the Tax Authority's application of Verba 28.1 GTSD to a construction site valued at €3,849,508.23 was illegal. The assessment totaling €38,495.08 for 2013 was cancelled. The tribunal determined that construction land does not qualify as 'property with residential purpose' under item 28.1 of the General Stamp Tax Table as amended by Law 55-A/2012. The decision emphasized that tax legislation must be interpreted strictly according to its letter and spirit, and the undefined term 'residential purpose' cannot be extended to include undeveloped construction sites that lack any actual residential use or allocation.
Is it unconstitutional to tax construction land under Verba 28.1 TGIS as amended by Law 55-A/2012?
Yes, the claimant in process 477/2014-T argued that taxing construction land under Verba 28.1 GTGIS violated the Portuguese Constitution. The challenge invoked Articles 13 (equality principle), 81 (economic tasks of the state), 103(3) (tax legality and typicity), and 104 (taxation of income and wealth) of the Portuguese Constitution. The argument centered on the principle of tax legality requiring clear, precise legal definitions for tax obligations. By extending Verba 28.1—which expressly refers to 'property with residential purpose'—to construction land without legal basis, the assessment potentially violated constitutional requirements for legal certainty, equal treatment, and the principle that taxes must be created by law with clearly defined taxable events. While the tribunal resolved the case on statutory grounds, the constitutional dimension highlighted fundamental concerns about arbitrary tax expansion beyond legislative intent.
How can property owners challenge unlawful Stamp Tax assessments through CAAD tax arbitration in Portugal?
Property owners can challenge unlawful Stamp Tax assessments through CAAD (Centro de Arbitragem Administrativa) tax arbitration under Decree-Law 10/2011 (RJAT—Legal Framework for Tax Arbitration). As demonstrated in process 477/2014-T, taxpayers file a request for constitution of an arbitral tribunal within the statutory deadline, specifying the contested assessment and legal grounds. The process offers advantages over judicial review: faster resolution (this case was decided within months of the September 2014 tribunal constitution), specialized tax expertise, lower costs, and binding decisions. Taxpayers can represent themselves or use legal counsel, present documentary evidence, and invoke both legality and constitutionality arguments. If the Tax Authority's assessment violates substantive or procedural law—such as misapplying Verba 28.1 GTSD to property categories outside its scope—CAAD arbitrators have authority to annul illegal assessments and order refunds of amounts paid.
