Summary

This CAAD arbitral decision (Process 658/2017-T) examines whether Stamp Tax under clause 28.1 of the General Stamp Tax Table (TGIS) applies to building land (terrenos para construção) valued over one million euros. The claimant, a real estate investment fund, challenged two Stamp Tax assessments from 2014, arguing that taxation requires three cumulative elements: ownership of real rights, patrimonial value exceeding €1,000,000, and actual authorized or planned residential construction. The fund contended that mere matrix registration as 'building land' is insufficient without an approved construction project specifically for residential purposes. Subsidiarily, the claimant invoked unconstitutionality of clause 28.1 TGIS for violating the equality principle (Article 13 CRP), arguing it creates arbitrary distinctions by taxing only certain high-value properties while excluding others with different allocations or multiple lower-value properties totaling over €1 million. The Tax Authority defended the assessments as lawful, asserting direct application based on matrix classification with residential allocation, and raised a preliminary objection regarding CAAD's incompetence to rule on constitutional matters. The case highlights critical interpretative questions about whether 'authorized or planned construction' must be actually approved through administrative processes or whether matrix classification alone suffices for taxation. The decision impacts real estate investment funds and property owners regarding high-value urban land taxation, official review procedures (revisão oficiosa), and the scope of CAAD arbitral jurisdiction in constitutional challenges.

ARBITRAL DECISION

REPORT

A..., S.A. on behalf of B... – Open Real Estate Investment Fund, with the tax identification number ..., with registered office at Rua ..., no. ..., ..., ... – ... Lisbon, hereinafter referred to as the Claimant, presented on 18/12/2017 a request for constitution of an arbitral tribunal and for an arbitral decision concerning the dispatch rejecting the request for official revision of the tax act of Stamp Tax assessment (2014), of the property registered in the urban property matrix under article ..., parish of ..., municipality of ... and the dispatch rejecting the request for official revision of the tax act of Stamp Tax assessment (2014), of the property registered in the urban property matrix under article ..., of the union of parishes of ... and ..., municipality of ...

The Honourable President of the Ethics Council of the Centre for Administrative Arbitration (CAAD) appointed on 07/02/2018 as arbitrator, Francisco Nicolau Domingos.

On 27/02/2018 the arbitral tribunal was constituted.

In compliance with the provision of article 17, nos. 1 and 2 of Decree-Law no. 10/2011, of 20 January (RJAT), the Respondent was notified on 27/02/2017 to, if so wished, present a response, request the production of additional evidence and to remit the administrative case (PA).

On 06/04/2018 the Respondent presented its response in which it alleges the incompetence of the arbitral tribunal to assess the request for declaration of material unconstitutionality of item 28.1 of the General Stamp Tax Table (TGIS) and subsidiarily the dismissal of the request for an arbitral decision, in view of the legality of the assessments.

On 09/04/2018 the tribunal, by dispatch, ordered the notification of the Claimant so that, if it so wished, it could pronounce itself on the matter of the exception.

The Claimant made no statement.

By dispatch dated 26/04/2018 the tribunal deferred the consideration of the matter of the exception to the final decision and decided to dispense with the holding of the meeting referred to in article 18, no. 1 of the RJAT, on the basis of the principle of autonomy of the arbitral tribunal in the conduct of the proceedings and in determining the rules to be observed with a view to obtaining, within a reasonable period, a decision on the merits of the claims made, cf. article 16, para. c) of the RJAT, granted a time period for the parties, if they so wished, to present written final submissions and set a deadline for issuing the arbitral decision.

The Claimant on 27/04/2018 presented a request renouncing the production of submissions.

The Respondent did not present written final submissions.

POSITION OF THE PARTIES

The Claimant alleges that, with the provision of item 28 of the TGIS, the legislator intended to establish a special taxation that applies only to properties with a value exceeding one million euros, taxing the wealth and economic capacity of taxpayers.

However, taxation achieved with reference to properties registered in the matrix as "land for construction" is not, in its view, applicable to the case under scrutiny. For this to occur, actual construction authorized or planned would be required for residential purposes.

To formulate this conclusion, it states that item 28.1 of the TGIS, as amended by Law no. 83-C/2013, of 31 December, provides for the taxation of "land for construction" whose construction, authorized or planned, is for residential purposes and whose tax patrimonial value (VPT) is equal to or greater than 1,000,000.00 €. That is, the taxable event generating Stamp Tax consists of three cumulative elements: i) the ownership of the real right over the property; ii) the VPT of the property and iii) construction authorized or planned for residential purposes.

Taxation in question shall only be applicable in situations where actual construction of the "land" has been authorized or planned in the specific case and such construction is intended for "residential" purposes. Thus, mere registration of the property in the matrix as "land for construction" does not legitimize the application of item 28 of the TGIS; there must always be the existence of an administrative process associated with construction, a construction permit/authorization (valid) and a project (approved), and this must be intended for residential purposes.

If the properties in question did not have in 2014 authorized or planned construction for residential purposes, the taxation enshrined in item 28.1 of the TGIS could not have been applied, as not all application prerequisites were met. Or, put another way, the dismissal of the revision requests and the underlying assessments are illegal due to error in the factual and legal premises.

Subsidiarily, the Claimant invokes the unconstitutionality of item 28.1 of the TGIS when applied to "land for construction", for violation of the principle of equality, enshrined in article 13 of the Constitution of the Portuguese Republic (CRP).

In its argumentative framework it observes that: i) the violation of the constitutional principle of equality stems from the fact that the relevant taxable event is restricted only to a portion of real estate property allocated or intended for residential purposes with a value exceeding 1,000,000.00 €, with all remaining high-value property allocated to other purposes being excluded from the scope of taxation; ii) the special taxation, as it has been implemented – by applying to urban properties considered individually – does not effectively burden all owners who have high-value property, because if an owner has only a single urban property and it has a tax patrimonial value exceeding 1,000,000.00 € they will be subject to special taxation, whereas if an owner has multiple urban properties with individual values below 1,000,000.00 € but which in total far exceed that amount, they are not subject to this special taxation; iii) item 28 of the TGIS constitutes double taxation of the same taxable event, the ownership of a real right, a circumstance that generates negative discrimination against certain taxpayers in relation to others who, on the same taxable event, have only been subject to a single tax and iv) item 28.1 of the TGIS, with respect to "land for construction", does not provide any limitation on its application based on the value of authorized or planned "residential" buildings; its application depends only on the VPT of the "land" itself, disregarding the value of the buildings provided for or authorized therein.

It concludes by requesting reimbursement of the amount of Stamp Tax assessments that it timely paid, in view of their illegality, and the condemnation of the Respondent to payment of compensatory interest, to the extent that it considers there to be "error attributable to the services".

The Respondent presents a defense with subsidiary grounds as follows:

Material Incompetence of the Arbitral Tribunal

The arbitral tribunal is incompetent to assess the request for declaration of material unconstitutionality, since the competence of arbitral tribunals constituted under the CAAD does not include the assessment of the constitutional conformity of legislative acts or their provisions.

Error in the Factual and Legal Premises

It defends itself by contesting, sustaining that the assessments which are the subject of these proceedings were made by direct application of the legal norm and the "land for construction" is allocated to residential purposes. If in the course of their respective valuations residential allocation was assigned, appearing in the matrices, it is subject to Stamp Tax.

Unconstitutionality of Item 28 of the TGIS

There is no alleged unconstitutionality, to the extent that the choice of this mechanism is applicable indistinctly to all and any holders of real property with residential allocation with a value exceeding 1,000,000.00 €, applying to wealth embodied and manifested in the value of real properties.

Reimbursement of Stamp Tax Amounts Paid and Condemnation to Payment of Compensatory Interest

The assessments that are the subject of the revision request of the tax act should be maintained in the legal order, therefore there is no basis for reimbursement of the amounts of Stamp Tax delivered.

On the other hand, if the Tax and Customs Authority (AT) made an application of the law in the terms to which, as an executive body, it is constitutionally bound, one cannot speak of error attributable to the services and, thus, there is also no entitlement to compensatory interest.

In this sequence, the following issues are those which the tribunal must assess:

Whether the tribunal is competent to assess the request for material unconstitutionality of item 28 of the TGIS;

Whether the express dismissal/rejection of the requests for revision of the tax acts and the assessments which are the subject thereof suffer from error in the factual and legal premises;

Whether item 28 of the TGIS should be disapplied, in the specific case, for violation of the constitutional principle of equality;

Whether the AT should be condemned to reimburse the Claimant for the amount of Stamp Tax paid in relation to the assessments that are the subject of the requests for revision of the tax acts;

Whether the AT should be condemned to pay compensatory interest to the Claimant.

PRELIMINARY ISSUES AND CASE MANAGEMENT

Incompetence of the Arbitral Tribunal

The Respondent argues that the tribunal is not competent to assess or declare the (un)constitutionality of item 28 of the TGIS, since abstract review of legality and constitutionality is reserved to the Constitutional Court.

Would the Respondent be correct?

In this respect, it is universally accepted that the application of a materially unconstitutional provision in the context of tax assessment results in its annulment, as it suffers from the defect of violation of law arising from error in the legal premises.

Now, what the Claimant is questioning is the application of a provision which it considers unconstitutional, item 28 of the TGIS, and not abstract review of constitutionality.

Thus, the exception raised by the Respondent is deemed not to be well-founded.

On the other hand, in the review proceedings numbers ...2016... and ...2017..., the AT determined their summary rejection. Therefore, it is legitimate to question: is the tribunal competent to assess the request for an arbitral decision filed against the dispatches summarily rejecting the requests for official revision?

Absolute incompetence constitutes a dilatory exception preventing consideration of the merits of the case, as determined by article 576, nos. 1 and 2 of the Code of Civil Procedure (CPC), applicable by virtue of article 29, no. 1, para. e) of the RJAT, which the tribunal must consider ex officio.

As JORGE LOPES DE SOUSA teaches[1] with respect to judicial challenge: "There are acts in tax matters that are challenged by means of a special administrative action, as follows from para. p) and no. 2 of article 97 of the CPPT. From these provisions it follows that the special administrative action is the appropriate procedural means when the act to be challenged is one of total or partial dismissal or revocation of exemptions or other tax benefits, when dependent on recognition by the tax administration, and other administrative acts relating to tax matters that do not involve assessment of the legality of a tax assessment act. From this article it clearly follows that, in cases where the act to be challenged is a tax assessment act or an act that involves assessment of the legality of a tax assessment act (act of dismissal of a gracious complaint or of hierarchical appeal filed against the decision ruling on it or an act assessing a request for official revision, as per article 78 of the LGT) the appropriate means is the challenge procedure".

The position referred to above is applicable to arbitral tribunals constituted under the CAAD, that is, by application of article 2 of the RJAT, excluded from the competence of these tribunals is assessment of the legality of administrative acts of total or partial dismissal or revocation of exemptions or other tax benefits, when dependent on recognition by the AT, as well as administrative acts relating to tax matters that do not involve assessment of the tax assessment act, to which article 97, no. 1, para. p) of the Code of Tax Procedure and Process (CPPT) refers. Or, put another way, the competence of arbitral tribunals includes assessment of the legality of tax assessment acts.

Thus, it is necessary to inquire whether the specific case is appropriate for the procedural means – request for an arbitral decision, as a means of reaction to acts rejecting requests for official revision. The answer thus consists in determining whether in those decisions the AT assessed or did not assess the legality of the Stamp Tax assessments which are the subject of these proceedings.

Analyzing the question, it appears that the AT did not merely reject the revision requests; rather, it even concludes that no error attributable to the services occurred, that is, it assessed the legality of the Stamp Tax assessments. Now, if that is the case, the dilatory exception referred to above does not apply.

Case Management

The cumulation of requests underlying these proceedings is admissible, in so far as there is identity between the matter of fact and the merits thereof depend on the interpretation of the same principles and rules of law, cf. article 3, no. 1 of the RJAT. On the other hand, the subject matter of the proceedings involves the same tax, that of Stamp Tax.

The proceedings are not affected by nullities; the arbitral tribunal is regularly constituted and is materially competent to know and decide the request, with the conditions consequently being met for the final decision to be rendered.

4.3. Basis for the Factual Matter Deemed Proven

The factual matter deemed proven originates from the documents used for each of the alleged facts and whose authenticity was not called into question.

5. LEGAL MATTER

Considering that the arbitral process has as its source two requests for official revision of the tax act, let us begin with the one concerning the property registered in the urban property matrix under article..., of the parish of .... municipality of ....

The first issue which the tribunal must address consists in determining whether, in the case in question, there exists error attributable to the services, since from this stems the determination of the period for challenge.

To do so it is necessary to identify, firstly, the applicable provision, that is, article 78 of the General Tax Law (LGT), which provides as follows:

"1. Revision of tax acts by the entity that made them may be effected at the initiative of the taxpayer, within the period for administrative complaint and on the basis of any illegality, or, at the initiative of the tax administration, within four years after assessment or at any time if the tax has not yet been paid, on the basis of error attributable to the services.

2. Revoked.

3. Revision of tax acts pursuant to no. 1, regardless of whether it is a material or legal error, implies its respective recognition duly reasoned in accordance with no. 1 of the preceding article.

4. The head of the service may authorize, exceptionally, within the three years following that of the tax act, revision of the taxable matter determined on the basis of serious or notorious injustice, provided that the error is not attributable to negligent conduct by the taxpayer.

5. For the purposes of the preceding number, only ostensive and unequivocal notorious injustice and grave injustice resulting from manifestly excessive and disproportionate taxation with reality or from which significant prejudice has resulted for the National Treasury are deemed serious.

6. Revision of the tax act on the grounds of duplicate collection may be effected, whatever the basis, within four years.

7. The period for official revision of the tax act or of the taxable matter is interrupted by the taxpayer's request addressed to the competent body of the tax administration for its realization".

The institution of revision constitutes an implementation of the duty to revoke illegal acts and, as such, the AT should proceed in this manner in cases where errors occur in assessments that result in the collection of taxes in an amount exceeding that legally provided for. The principles of justice, equality and legality that inform the activity of the AT impose this official correction.

Thus, while on one hand revision of the act is admissible at the taxpayer's initiative within the period for administrative challenge, on the other, the AT, at the taxpayer's request, may also promote the so-called "official revision".

In this sense, case law[2] affirms that: "It follows from the law and constitutes settled case law of this Supreme Court that official revision of tax acts to which the latter part of no. 1, article 78 of the LGT 'at the initiative of the tax administration' may be carried out at the taxpayer's request (article 78, no. 7 of the LGT), and the dismissal, express or implied, of such revision request is susceptible to contentious challenge, in accordance with article 95, nos. 1 and 2, para. d) of the LGT and article 97, no. 1, para. d) of the CPPT, when what is at issue is assessment of the legality of the assessment act and this possibility is not prejudiced by the fact that the request for official revision was presented long after the periods for administrative challenge were exhausted, but within the 4-year period for revision of the assessment act 'at the initiative of the tax administration'".

The revision request must also be based on "error attributable to the services" and be presented within the four-year period. Now, this error encompasses oversight, material or factual error, as well as legal error.

In support of the latter conclusion, case law[3] also states: "…this Supreme Court has for a long time understood in settled fashion that where there exists a legal error in an assessment made by the services of the tax administration, and this incorrect application of the law does not result from any information or declaration by the taxpayer, the error in question is attributable to the services, since both no. 2 of article 266 of the Constitution and article 55 of the General Tax Law establish the generic obligation of the tax administration to act in full compliance with the law,…".

"Official revision" requires that, cumulatively, the following requirements be met: i) the request be formulated within four years from the act whose revision is requested or at any time when the tax has not been paid; ii) it originates from "error attributable to the services" and iii) it proceeds from the taxpayer's initiative or is carried out officially by the AT.

Thus, after the period for judicial challenge or gracious complaint has elapsed, article 78, nos. 1, 3 and 4 of the LGT establishes as an essential requirement for "official revision" that the error be attributable to the services. "Error attributable to the services" admits pathology in fact and in law; however, illegality cannot be attributable to the taxpayer due to negligent conduct, but to the AT.

This is the position of the Supreme Administrative Court when it states that: "…any illegality not resulting from conduct by the passive subject is attributable to the Administration itself, and this attributability to the services is independent of demonstration of fault by any of the officials involved in the issuance of the act affected by the error,…"[4]. And, in the same sense: "…it is to the tax administration that this error is attributable, whenever the incorrect application of the law is not based on any information from the taxpayer"[5].

The doctrine, beyond agreeing with the case law position referred to above, teaches that "error attributable to the services" concretizes any relevant illegality, not attributable to the taxpayer due to negligent conduct, but to the Tax Administration[6]. As it also observes that there will be "error attributable to the services" when, despite the assessment having been made on the basis of the taxpayer's declaration, the latter has adopted a generic guidance from the AT duly published, due to defective performance of the latter's duty of collaboration[7]. It happens that, this is manifestly not what occurs in the present case, to the extent that the IMI form 1 declarations were not presented with support in any generic information, a matter that is not even alleged.

Reverting the said position to the specific case, it was the Claimant who presented the IMI form 1 declaration with the number ... in which it declared that the land was intended for construction. As well as, on 31/12/2014, it submitted a new IMI form 1 declaration no...., for the following reason "request for valuation-VPT outdated". And let it not be forgotten that at the date of the taxable event, article 67, no. 2 of the Stamp Tax Code (CIS) determined that: "For matters not regulated in this Code relating to item no. 28 of the General Table, the provisions of the CIMI shall apply subsidiarily". This Decree which in its article 113, no. 1 provides: "The tax is assessed annually, in relation to each municipality, by the central services of the Directorate-General of Taxes, based on the tax patrimonial values of properties and in relation to passive subjects that appear in the matrices on 31 December of the year to which it relates". Now, the assessment relating to said property was made on the basis of the content of the IMI form 1 declarations, confirmed after valuation. Or, put another way, on the basis of the taxpayer's declaration. For which reason, the essential requirement for revision is not fulfilled, that is, that the error be attributable to the services.

And what about the request for revision concerning the property registered under article ..., urban, of the union of parishes of ... and ...?

Let us state in advance that the conclusion is similar, that is, there is no error attributable to the services. Indeed, on 23/01/2013 the Finance Service of ... submitted the IMI form 1 declaration for the reason – general valuation. Now, the matrix registration that determined the Stamp Tax assessment originates from a general valuation and, in such cases, the passive subject is obligated to deliver the approved form 1 declaration, article 67, no. 2 of the CIS and article 16, no. 2 of the Code of Municipal Real Estate Tax (CIMI). Moreover, the Claimant was notified of the content of the valuation and did not complain. For this reason, there is negligence attributable to the Claimant that prevents revision.

In sum, the period for using the arbitral route had already expired on 18/12/2017, the date of presentation of the request for constitution of a tribunal and arbitral decision, generating the peremptory exception of expiration and the consequent dismissal of the requests, in accordance with article 576 of the CPC, applicable ex vi article 29 of the RJAT.

6. DECISION

In these terms, it is decided that the request for an arbitral decision is completely without merit, with all legal consequences.

7. VALUE OF THE PROCEEDINGS

The value of the proceedings is set at 44,117.80 €, in accordance with article 97-A of the CPPT, applicable by virtue of article 29, no. 1, para. a) of the RJAT and article 3, no. 2 of the Costs Regulation in Tax Arbitration Proceedings (RCPAT).

8. COSTS

Costs to be borne by the Claimant, in the amount of 2,142 €, cf. article 22, no. 4 of the RJAT and Table I attached to the RCPAT.

Frequently Asked Questions

Automatically Created

Does Stamp Tax (Imposto do Selo) under clause 28.1 of the TGIS apply to building land (terrenos para construção) valued over one million euros?
Clause 28.1 of the General Stamp Tax Table applies to building land (terrenos para construção) with patrimonial value equal to or exceeding €1,000,000 when construction is authorized or planned for residential purposes. The central dispute is whether this requires actual approved construction projects through administrative processes, or whether matrix registration as 'building land' with residential allocation suffices. The claimant argues that mere matrix classification is insufficient and actual authorized or planned residential construction must exist through valid permits and approved projects. The Tax Authority contends that matrix registration with residential allocation is adequate for taxation under direct application of the legal norm.
Can CAAD arbitral tribunals rule on the constitutional validity of clause 28.1 of the General Stamp Tax Table?
CAAD arbitral tribunals face jurisdictional limitations regarding constitutional review. The Tax Authority raised a preliminary objection arguing that arbitral tribunals constituted under CAAD lack competence to assess the material unconstitutionality of legislative acts or their provisions. This procedural objection challenges the tribunal's authority to rule on the claimant's subsidiary argument that clause 28.1 TGIS violates Article 13 of the Portuguese Constitution (principle of equality). The tribunal deferred consideration of this exception to the final decision, but the jurisdictional question remains fundamental to determining whether CAAD can address constitutional conformity issues or whether such matters belong exclusively to Constitutional Court jurisdiction.
What is the process for requesting an official review (revisão oficiosa) of Stamp Tax assessments on high-value urban properties in Portugal?
The official review (revisão oficiosa) process for Stamp Tax assessments on high-value urban properties begins with submission of a request to the Tax Authority challenging the assessment's legality. If the Tax Authority issues a decision rejecting the revision request, taxpayers can escalate to arbitral proceedings at CAAD under the RJAT (Decree-Law 10/2011). The process requires payment of the disputed tax amount pending resolution. In this case, the claimant challenged Stamp Tax assessments from 2014 on two properties registered as urban land, following rejection of official revision requests. The arbitral procedure involves appointment of an arbitrator by the CAAD Ethics Council President, tribunal constitution, notification to the Tax Authority for response and submission of the administrative file (processo administrativo), potential hearings (which may be dispensed with), and issuance of a final arbitral decision within established deadlines.
Is the taxation of building land under clause 28.1 TGIS consistent with the constitutional principle of taxing wealth and economic capacity?
The taxation of building land under clause 28.1 TGIS raises constitutional questions regarding wealth and economic capacity taxation principles. The claimant argues the provision violates Article 13 CRP (equality principle) because: (1) it taxes only certain high-value residential properties exceeding €1 million while excluding other high-value properties for different purposes, creating arbitrary distinctions; (2) it taxes individual properties rather than aggregate wealth, allowing owners of multiple sub-€1 million properties totaling much higher values to escape taxation while single-property owners are taxed; (3) it creates double taxation on the same taxable event (ownership of real rights) alongside IMI (municipal property tax); and (4) for building land specifically, it taxes based solely on land value without considering the value of authorized or planned buildings. The Tax Authority defends the provision as constitutionally valid, applying indistinctly to all holders of residential real property exceeding €1 million, taxing wealth embodied in real property values.
How are real estate investment funds affected by Stamp Tax on urban properties inscribed in the property matrix as building land?
Real estate investment funds managing urban properties face significant Stamp Tax exposure under clause 28.1 TGIS when properties are inscribed in the matrix as building land (terrenos para construção) with values exceeding €1,000,000. In this case, the claimant fund (B... Open Real Estate Investment Fund, managed by A... S.A.) challenged assessments on properties registered as urban land, arguing that matrix classification alone is insufficient for taxation without actual authorized or planned residential construction projects. Investment funds must navigate interpretative uncertainty regarding whether 'authorized or planned construction' requires valid construction permits and approved projects, or whether matrix registration with residential allocation triggers taxation. The decision impacts fund asset management strategies, tax provisioning, property acquisition due diligence, and potential restructuring to avoid individual property values exceeding the €1 million threshold. Funds may seek declaratory clarity through official review procedures or arbitral challenge when assessments are issued based solely on matrix classification without underlying construction authorization.
