Source: Original CAAD Decision

Summary

CAAD Process 494/2014-T addresses the application of Item 28.1 of the General Stamp Tax Table (TGIS) to independent property units valued below the €1,000,000 threshold. The case involved 19 separate Stamp Tax assessments on property fractions (designated as 'Rights' and 'Lefts') of a building, each individually valued between €280,470 and €285,640, totaling approximately €53,000 in tax liability. The central legal issue concerns whether parts of a building susceptible to independent use should be taxed individually under Item 28.1 TGIS when each unit falls below the high-value property threshold, or whether the aggregate value of commonly-owned units should determine taxability. The claimant, acting as head of an estate, challenged the Tax Authority's position that each independently usable fraction constitutes a separate taxable event. This arbitration highlights critical interpretative questions about the scope of Stamp Tax on real estate following Law 55-A/2012 reforms, particularly regarding the definition of 'property' for taxation purposes when a building contains multiple autonomous units under single ownership. The case demonstrates taxpayers' ability to contest such assessments through CAAD's administrative arbitration system, which provides an alternative to traditional court litigation for tax disputes. The outcome has significant implications for property owners holding multiple independent units within the same building structure, affecting how Portuguese tax law treats fractional property ownership for Stamp Tax purposes.

ARBITRAL DECISION

CAAD: Tax Arbitration

Case No. 494/2014-T

Subject: IS – Parts of buildings susceptible of independent use – Item No. 28.1 of the General Stamp Tax Table (TGIS)

I – Report

  1. On 15.07.2014, the Claimant A, married, holder of the tax identification number ..., resident at Avenue ..., Cascais, in his capacity as head of the estate of B, with the tax identification number ..., requested the CAAD to constitute an arbitral tribunal, pursuant to article 10 of Decree-Law No. 10/2011, of 20 January (Legal Regime for Arbitration in Tax Matters, hereinafter referred to only as LRAT), in which the Tax and Customs Authority is the Respondent, with a view to the annulment of the following tax acts:

a) Assessment corresponding to document No. 2014 ..., item 28.1 TGIS for the year 2013, with a collection of €2,823.20, relating to the 1st Right of the urban registration article No. ..., parish of ..., with a registered value of €282,320.00, with assessment date of 17.03.2014 and payment limit date of the first installment in the amount of €941.08 on 30 April 2014;

The Claimant also petitioned in the request for constitution of an Arbitral Tribunal for compensatory interest, which it believes is due, having paid the amounts corresponding to the assessments relating to the year 2013 and mentioned above in items a) to s).

  1. The request for constitution of the arbitral tribunal was accepted by the Esteemed President of CAAD and notified to the Tax and Customs Authority.

In accordance with the terms and for the purposes of article 6, No. 1 of the LRAT, by decision of the President of the Deontological Council, duly communicated to the parties within the legally applicable time periods, the undersigned was appointed arbitrator, who communicated to the Deontological Council and to the Centre for Administrative Arbitration the acceptance of the appointment within the regularly applicable time period.

The Arbitral Tribunal was constituted on 1.10.2014.

  1. By arbitral order of 6.01.2015, following a request from the Respondent which met with the agreement of the Claimant, the meeting provided for in article 18 of the LRAT was dispensed with, given its unnecessary nature.

  2. The grounds presented by the Claimant in support of its claim were, in summary, the following:

i) The AT has no legal basis to assess this stamp tax according to item 28.1 of the respective table, in the wording given by article 4 of Law No. 55-A/2012, of 29 October, since the building in question is registered in terms of the provisions of article 12, No. 3 of the Code of the Municipal Property Tax (hereinafter CMPT), according to which: "Each story or part of a building susceptible of independent use is considered separately in the registration entry, which also specifies its respective tax patrimonial value." and has been valued in accordance with the provisions of article 7, No. 2, item b) of the CMPT, according to which: "The tax patrimonial value of urban buildings with parts that can be classified in more than one of the classifications in No. 1 of the previous article is determined: (…) b) If the different parts are economically independent, each part is valued by application of the corresponding rules, and the value of the building is the sum of the values of its parts."

ii) The Respondent considered the value resulting from the sum of 13 units of the building in question, arriving at the amount of €3,580,110.00, from which, with respect to the 2011 stamp tax, assessed in 2012, it deducted the TPV of the two shops and the ground floor of the building, with municipal authorization for commercial activity, obtaining as a result the amount of €1,464,519.00 and – With respect to the 2013 stamp tax, assessed in 2014, it deducted the TPV of the two shops and the ground floor and the 1st left of the building, with municipal authorization for commercial activity, obtaining as a result the amount of €2,545,860.00 and, insofar as this result exceeds the value of one million euros, it understood that the building was subject to the objective incidence of the aforementioned item 28.1 of the TGIS, but it was based on the TPV of each of the units of the building that it carried out the assessments in question, now being contested.

iii) For purposes of IMI and item 28.1 of the TGIS, what is relevant is the autonomy reflected in an autonomous patrimonial value, if greater than €1,000,000, combined with the requirement that that unit be allocated to housing and not to commercial use, and none of the assessments now in question, being contested, were based on a value above €1,000,000.00 (one million euros).

iv) The assessments in question are not only illegal but also unconstitutional, as they violate the principle of Equality constitutionally enshrined, article 13 of the CRP, which in the context of Tax Law is implemented by the Principle of Taxpaying Capacity, because, if the building were constituted in horizontal property, the tax situation of the building itself, as well as that of each of the parts that compose it, would not diminish its taxpaying capacity.

v) The distinction between horizontal property/vertical property cannot be a criterion for inclusion/exclusion of the incidence of stamp tax on buildings/units with the same physical units, equal patrimonial value and allocation of the same spaces to the same purposes, therefore the application of item 28 of the TGIS effected by the Respondent violates, thus, the principles of Equality and taxpaying capacity.

  1. The ATA – Tax and Customs Administration, called upon to present its position, contested the Claimant's claim, defending itself by objection, in summary, with the following grounds:

i) The subjection to stamp tax of item 28.1 of the General Table annexed to the CIS results from the combination of two facts, namely, the residential allocation and the patrimonial value of each urban building registered in the matrix being equal to or greater than €1,000,000.00.

ii) The situation of the Claimant's building falls, linearly, which is to say, literally, within the scope of the item in question, since only the autonomous fractions of a building in horizontal property regime are considered as buildings – No. 4 of the aforementioned article 2 of the CMPT, therefore, since the building in question is in the regime of full ownership, it does not possess autonomous fractions, to which tax law attributes the qualification of building, therefore the present claimant, for purposes of IMI and also of stamp tax, by virtue of the wording of the aforementioned item, is not the owner of 9 autonomous fractions, but rather of a single building.

iii) We cannot, therefore, accept that one considers, that for purposes of item 28.1 of the General Table annexed to the CIS, that the parts susceptible of independent use have the same tax regime as the autonomous fractions of the horizontal property regime.

iv) Since the building is subject to the regime of full ownership, but is physically composed of parts susceptible of independent use, tax law attributed relevance to this materiality, evaluating these parts individually, in accordance with article 12 and consequently, in accordance with article 12, No. 3, of the C.I.M.I., each story or part of a building susceptible of independent use is considered separately in the registration entry, but in the same matrix, proceeding with the assessment of IMI taking into account the tax patrimonial value of each part.

v) The fact that the IMI was determined based on the tax patrimonial value of each part of a building with economically independent use does not equally affect the application of item 28, No. 1, of the General Table, as results from the determining fact of the application of that item of the General Table being the total patrimonial value of the building and not separately that of each of its parcels.

vi) Any other interpretation would violate, indeed, the letter and spirit of item 28.1 of the General Table and the principle of legality of the essential elements of the tax provided for in article 103, No. 2, of the Constitution of the Portuguese Republic (CRP).

vii) It is therefore unconstitutional, as it offends the principle of tax legality, the interpretation of item 28.1 of the General Table, to the effect that the patrimonial value on which its incidence depends be determined globally and not story by story or story or division by division.

viii) It is not apparent how, on the other hand, the taxation in question could have violated the principle of equality and the principle of the prevalence of material truth referred to by the claimant, since horizontal property and vertical property are differentiated legal institutions.

ix) The constitution of horizontal property implies, indeed, a mere legal alteration of the building, with no new valuation, but the legislator can, however, subject to a distinct tax legal framework, and therefore discriminatory, buildings in regimes of horizontal and vertical property, in particular, benefiting the legally more evolved institute of horizontal property, without such discrimination being necessarily considered arbitrary.

x) Such discrimination can also be imposed by the need to impose coherence to the tax system.

  1. On 12.12.2014, the Claimant presented a subsequent pleading alleging that it had paid on 13.10.2014 the tax installments mentioned above in items t) to ee) of point 1, relating to the assessments provided for in article 6, No. 1 of Law 55-A/2012, of 29 October, requesting the extension of the claim and petitioning for the reimbursement of the amounts paid, respective compensatory interest and also for the return of costs paid in the respective executive proceedings instituted as a result of the non-voluntary payment of the amounts corresponding to the tax installments in question.

The Respondent, notified, did not present its position, with the Tribunal admitting the pleading in question and the requested extension.

  1. The parties presented written allegations in which, in essence, they maintained their positions.

  2. The tribunal is materially competent and is regularly constituted in accordance with the LRAT.

The parties have legal personality and capacity, are entitled and are legally represented.

The proceedings are not vitiated by defects that would invalidate them.

II – The Relevant Facts

  1. The tribunal considers the following facts to be proven:

  2. The claimant A is the head of the undivided estate of B, with tax identification number ….

  3. Part of this undivided estate is the urban building located at ..., parish of ..., municipality of Lisbon, with registration article ..., of the parish of ... and described in the Land Registry Office of Lisbon under No. ….

  4. The building in question consists of a basement, 2 shops, ground floor and six stories, stories with independent use, in the following terms:

a) Shop 32, the ground floor and 1st left with authorization for use No. …, issued by Lisbon City Council on 20.11.1996 which allocates them to commercial use, as well as shop 48 A intended for commercial use;

b) The 1st right, 2nd right, 3rd right, 4th right, 5th right, 2nd left, 3rd left, 4th left and 5th left, all autonomous units that maintain the purpose described in the Inspection Report for housing and occupancy issued at the time of its construction, on 9.11.1946, according to which: "housing authorization may be granted for 12 units, with 1 for caretaker on the top floor and occupancy authorization for 1 occupancy from December of nineteen hundred and forty-six. The experts also verified that this building was vacant and occupied on the 1st story right."

c) The 6th story is currently vacant and maintains in the matrix the original intended use as "caretaker's unit."

  1. The division that characterizes the building leads to the fact that, annually, the AT, for purposes of IMI, carries out the legal operations of assessment of this tax, based on the tax patrimonial value of each of its 13 physical and economically autonomous units.

  2. All these 13 physical and economically autonomous units, individually considered, have a tax patrimonial value less than one million euros.

  3. The AT understood that the building is subject to the objective incidence of item No. 28.1 of the TGIS, since the sum of the patrimonial value of each of its aforementioned physical and economically independent units exceeds the sum of one million euros.

  4. On 24 April 2014, the Claimant proceeded to pay the first installments of the nine assessments of item 28.1 of the TGIS relating to the year 2013, in the total of €8,486.26.

  5. On 1 July 2014 it proceeded to pay the second installments of the nine assessments of item 28.1 of the TGIS also relating to the year 2013, in the total of €8,486.17.

  6. On 13.10.2014 the claimant proceeded to pay the ten assessments, effected in accordance with article 6, No. 1 of Law 55-A/2012, of 29 October, and in addition to the value of the tax paid, it also paid costs relating to the executive proceedings instituted for each of the stamp tax assessments, in the following terms:

i) Stamp Tax Assessment No. 2014 … with collection of €584.59, costs in the amount of €22.05, in a total of €606.64;

ii) Stamp Tax Assessment No. 2014 …, with collection of €692.91, costs in the amount of €22.05, in a total of €714.96;

iii) Stamp Tax Assessment No. 2014 …, with collection of €1,096.31 costs in the amount of €29.90, in a total of €1,126.21;

iv) Stamp Tax Assessment No. 2014 …, with collection of €313.84, costs in the amount of €19.10, in a total of €332.94;

v) Stamp Tax Assessment No. 2014 …, with collection of €622.21, costs in the amount of €22.05, in a total of €644.26;

vi) Stamp Tax Assessment No. 2014 …, with collection of €413.53, costs in the amount of €19.10, in a total of €432.63;

vii) Stamp Tax Assessment No. 2014 …, with collection of €2,885.06, costs in the amount of €53.18, in a total of €2,938.24;

viii) Stamp Tax Assessment No. 2014 …, with collection of €167.60, costs in the amount of €19.10, in a total of €186.70;

ix) Stamp Tax Assessment No. 2014 …, with collection of €4,179.44, costs in the amount of €69.81, in a total of €4,249.25;

x) Stamp Tax Assessment No. 2014 …, with collection of €760.66, costs in the amount of €25.38, in a total of €786.04;

  1. The deadline for voluntary payment of these assessments had expired on 31.08.2014.

  2. The tribunal's conviction regarding the decision of the facts was based on the documents contained in the proceedings, it being noteworthy that the parties did not manifest any disagreement regarding the facts, with the disagreement being limited to the matters of law.

III – Applicable Law

  1. Item 28 of the General Table of Stamp Tax, in the wording at the time of the facts, provided that urban buildings with residential allocation with TPV equal to or greater than €1,000,000 are subject to stamp tax, in the following terms:

"28 – Ownership, usufruct or surface right of urban buildings whose tax patrimonial value in the matrix, in accordance with the Code of Municipal Property Tax (CMPT), is equal to or greater than €1,000,000 – on the tax patrimonial value used for purposes of IMI:

28.1 – For a building with residential allocation – 1%;

28.2 – For a building, when taxpayers who are not natural persons are residents in a country, territory or region subject to a clearly more favorable tax regime, contained in the list approved by order of the Minister of Finance – 7.5%".

  1. Article 67, No. 2 of the CIS establishes that "To matters not regulated in this Code relating to item No. 28 of the General Table, the provisions of the CMPT apply, subsidiarily".

  2. Article 2, No. 4 of the Code of Municipal Property Tax (hereinafter CMPT) provides that "For purposes of this tax, each autonomous fraction, in the horizontal property regime, is considered as constituting a building".

It further establishes article 92 of the same code:

"1 – Each building in the horizontal property regime corresponds to a single entry in the matrix.

2 – In the generic description of the building reference must be made to the fact that it is in the horizontal property regime.

3 – Each of the autonomous fractions is described in detail and individualized by the capital letter that corresponds to it according to alphabetical order."

  1. In turn, article 12, No. 3 of this Code establishes that "Each story or part of a building susceptible of independent use is considered separately in the registration entry, which also specifies its respective tax patrimonial value".[1]

Writing on this norm, J. Silvério Mateus and L. Corvelo de Freitas tell us: "An example that can illustrate this situation is the case of an urban building, not constituted in horizontal property and which is composed of several stories. Legally this building constitutes a single unit (…).

However, since each of these units can be the object of lease or any other use by the respective owner, the matrix must evidence these units and tax patrimonial value must be attributed to each of them".[2]

It appears, therefore, that article 12, No. 3 is applicable to situations of buildings in conditions to satisfy the objective requirements for submission to the horizontal property regime, provided for in article 1415 of the Civil Code, but in which the existence of a constitutive title does not occur.

  1. With respect to urban buildings in conditions to satisfy the objective requirements for submission to the horizontal property regime, in substance, the economic reality subject to taxation does not cease to be the same by reason of whether or not the act establishing horizontal property has occurred.

And, in the perspective of the taxation of these realities, there is no substantive difference in the CMPT in the treatment of a property depending on the constitution of horizontal property.

  1. Indeed, in the regime of articles 38 et seq. of the CMPT that regulate the determination of the tax patrimonial value of properties, no substantive differentiation is detected between properties constituted in horizontal property and properties with objective conditions for such, but in which submission to such a regime has not occurred[3], in particular, such circumstances do not appear in the increasing or decreasing elements provided for in the tables of articles 43, No. 2 of the code.

  2. The essential question to be resolved in the present proceedings relates to the question of whether in buildings with parts susceptible of independent use, but not submitted to the horizontal property regime, the property shall be considered as one unit for purposes of applying item 28 of the TGIS or whether its independent parts shall be considered individually.

  3. In the first case, the value relevant for purposes of subsumption to item 28 shall be that resulting from the consideration of all of its parts and, in coherence, only one assessment should be carried out, solely relating to the property, and not as many assessments as there are parts or stories susceptible of independent use.

  4. In the second case, the value to be considered for the purpose shall be that of each of the parts susceptible of independent use, similarly to what occurs with the autonomous fractions of buildings submitted to the horizontal property regime, and as many assessments should be carried out as there are parts susceptible of independent use, but only and solely with respect to parts susceptible of independent use whose value is equal to or greater than €1,000,000.

  5. The AT carried out as many assessments as there are parts susceptible of independent use, a procedure which, in our view, does not harmonize with its own thesis that, in these cases, the reality targeted by Item 28 of the TGIS is the property as a whole and not each of its autonomous parts.

  6. The question has already been addressed in several arbitral decisions[4], all to the effect of considering that the value to be considered for the purpose shall be that of each of the parts susceptible of independent use, similarly to what occurs with the autonomous fractions of buildings submitted to the horizontal property regime, a solution which we consider to be correct.

  7. At a first moment of interpretation of item 28 of the TGIS, the expression "urban building", in conjunction with article 2, No. 4 of the CMPT, which attributes the quality of urban building to autonomous fractions in the horizontal property regime and, apparently, does not attribute it to parts susceptible of independent use, could point towards the consideration of the building as a whole.

  8. But, still within the scope of the literal element, item 28 points in a different direction by referring to "building with residential allocation", insofar as, in cases of buildings susceptible of independent use, the allocation can only be determined fraction by fraction[5] and not globally, insofar as it can happen, and frequently happens in this type of property, for there to be parts allocated to housing and others allocated to other purposes.

Thus, by referring to "building with residential allocation", with respect to buildings with stories or parts of a building susceptible of independent use, the legislator could only have had in mind each of these fractions and not the building as a whole.

  1. This reading of the literal element is in complete harmony with the norms of the CMPT mentioned above, as well as with the other interpretative elements, as demonstrated in the various CAAD decisions on this matter and to whose jurisprudence we adhere without reservation.

  2. As written in the decision rendered in case 50/2013-T:

"the ratio legis underlying the rule of item 28 of the TGIS, introduced by Law No. 55-A/2012 of 29 October, and in obedience to the provisions of article 9 of the Civil Code, according to which the interpretation of the legal norm should not be limited to the letter of the law, but should reconstruct from the texts and other interpretative elements the legislative thought, taking into account the unity of the legal system, the circumstances in which it was drawn up and the specific conditions of the time in which it is applied.

The legislator, in introducing this legislative innovation, considered as the determining element of taxpaying capacity urban buildings, with residential allocation, of high value (luxury), more precisely, of value equal to or greater than €1,000,000.00, on which it proceeded to impose a special stamp tax rate, intending to introduce a principle of taxation on wealth manifested in the ownership, usufruct or surface right of luxury urban buildings with residential allocation. Therefore, the criterion was the application of the new rate to urban buildings with residential allocation, whose TPV is equal to or greater than €1,000,000.00.

This is confirmed by the analysis of the discussion of bill No. 96/XII in the Assembly of the Republic, available for consultation in the Parliamentary Gazette, Series I, No. 9/XII/2, of 11 October 2012.

The justification for the measure called the "special rate on high-value residential urban buildings" is based on the invocation of the principles of social equity and tax justice, calling upon the holders of high-value properties intended for housing to contribute in a more intense manner, imposing the new special rate on "houses with value equal to or greater than 1 million euros."

Clearly the legislator understood that this value, when imputed to a residential unit (house, autonomous fraction or story with independent use) translates a taxpaying capacity above average and, as such, capable of determining a special contribution to guarantee fair distribution of the tax burden."

  1. The respondent further argues that it is unconstitutional, as it offends the principle of tax legality, the interpretation of item 28.1 of the General Table, to the effect that the patrimonial value on which its incidence depends be determined globally and not story by story or story or division by division.

It appears to us that it does not have grounds, due to the above and also because we do not see in what way the principle of legality can interfere with the application of the interpretative criteria provided for in article 9 of the Civil Code.

  1. On the other hand, it is understood that the interpretation sustained here, in line with the consistent arbitral jurisprudence mentioned above, is the one that harmonizes with the constitutional principles of tax equality and taxpaying capacity, insofar as it would not be acceptable in light of these principles the manifestly unequal taxation of substantially identical realities, merely for the formal reason that in some cases the constitution of horizontal property occurred and in others it did not.

  2. In the same vein goes the consideration of the principle of systematic coherence, which would also be affected by the consideration of these realities in the context of IMI with a substantially identical status to that of fractions of buildings formally constituted in horizontal property, contrary to what would occur in the context of stamp tax, in accordance with the solution sustained by the Respondent.

  3. Based on the foregoing, it is considered that in the case of urban buildings with parts or stories susceptible of independent use, the value to be considered for purposes of applying item 28 of the TGIS is the tax patrimonial value of each of those independent parts, with only the parts susceptible of independent use whose own tax patrimonial value is greater than €1,000,000 being subject to this tax.

  4. In the case at hand, since the tax patrimonial value of each of the parts susceptible of independent use is less than that value, they do not fall within the tax incidence norm, and therefore the assessments in question suffer from the defect of violation of law and cannot fail to be annulled.

  5. The Claimant further petitioned for the Respondent to be ordered to refund the amounts paid corresponding to the assessments relating to the year 2013 and to pay compensatory interest on such amounts and also, with respect to the assessments provided for in article 6, No. 1 of Law 55-A/2012, of 29 October, refund the amounts paid, respective compensatory interest and also return of costs paid in the respective executive proceedings instituted as a result of the non-voluntary payment of the amounts corresponding to the tax installments in question.

Let us see.

In accordance with the provisions of item b) of article 24 of the LRAT, the arbitral decision on the merits of the claim for which no appeal or objection lies binds the tax administration from the end of the period provided for appeal or objection, with this administration, in the exact terms of the success of the arbitral decision in favor of the taxpayer and until the end of the period provided for spontaneous execution of judgments of tax courts, being obliged to "restore the situation that would have existed if the tax act subject of the arbitral decision had not been practiced, adopting the acts and operations necessary for that purpose", which is in line with the provisions in article 100 of the LGT [applicable by virtue of the provisions in item a) of No. 1 of article 29 of the LRAT] which establishes that "the Tax Administration is obliged, in case of total or partial success of a complaint, judicial impugnation or appeal in favor of the taxpayer, to immediately and fully restore the legality of the act or situation subject of the dispute, including the payment of compensatory interest, if applicable, from the end of the period of execution of the decision".

Although article 2, No. 1, items a) and b), of the LRAT uses the expression "declaration of illegality" to define the competence of the arbitral tribunals operating in the CAAD, making no reference to condemnatory decisions, it should be understood that the powers attributed to courts in judicial impugnation proceedings are included in their competences, and this is the interpretation that is in keeping with the sense of the legislative authorization on which the Government based itself in approving the LRAT, in which it proclaims, as a first guideline, that "the tax arbitral process should constitute an alternative procedural means to the judicial impugnation process and to the action for the recognition of a right or legitimate interest in tax matters".[6]

The judicial impugnation process, although essentially a process of annulment of tax acts, admits the condemnation of the Tax Administration to the payment of compensatory interest, as is drawn from article 43, No. 1, of the LGT, which establishes that "compensatory interest is due when it is determined, in a gracious complaint or judicial impugnation, that there was error attributable to the services as a result of which the payment of the tax debt was made in an amount greater than legally due" and from article 61, No. 4 of the CPPT (in the wording given by Law No. 55-A/2010, of 31 December, which corresponds to No. 2 in the original wording), which provides that "if the decision recognizing the right to compensatory interest is judicial, the payment period is counted from the beginning of the period of spontaneous execution".

Thus, No. 5 of article 24 of the LRAT in saying that "payment of interest is due, regardless of its nature, in the terms provided for in the general tax law and in the Code of Tax Procedure and Process" should be understood as allowing the recognition of the right to compensatory interest in arbitral proceedings.

In the case at hand, it is manifest that, following the illegality of the assessment acts, reimbursement of the tax is warranted, by virtue of the aforementioned articles 24, No. 1, item b), of the LRAT and 100 of the LGT, since this is essential to "restore the situation that would have existed if the tax act subject of the arbitral decision had not been practiced", in the part corresponding to the correction that was considered illegal.

With respect to compensatory interest, it is also clear that the illegality of the act is attributable to the Tax and Customs Authority, which, on its own initiative, practiced it, as has been seen, without legal support.

There is a defect of violation of substantive law, embodied in error regarding the presuppositions of law, attributable to the Tax Administration.

Consequently, the Claimant is entitled to compensatory interest, in accordance with article 43, No. 1, of the LGT and article 61 of the CPPT, calculated on the amounts it paid indebted.

Thus, the Tax and Customs Authority should give execution to the present decision, in accordance with article 24, No. 1, of the LRAT, refunding that amount to the claimant, with compensatory interest, at the legal supplemental rate for civil debts, in accordance with articles 35, No. 10, and 43, Nos. 1 and 5, of the LGT, article 61 of the CPPT, article 559 of the Civil Code and Order No. 291/2003, of 8 April (or any subsequent decree(s)).

Compensatory interest is due from the date of payment until the date of processing of the credit note, in which they are included (article 61, No. 5, of the CPPT).

  1. The reasons just set forth for admitting the competence of the Arbitral Tribunals for the pronouncement of condemnatory decisions with respect to the payment of compensatory interest and the reimbursement of amounts paid corresponding to assessments declared illegal (competence which, apparently would not result from article 2, No. 1 of the LRAT) do not, however, have the scope of attributing to the tribunal powers to condemn the Respondent to payment of amounts other than those that do not derive directly from the declaration of illegality of the assessment.

The payment of costs by the Claimant did not result directly from the practice of illegal assessment acts, but from the absence of voluntary payment of the tax installments, it being known that in procedural and tax proceedings the principle of "solve et repete" prevails, according to which, to the taxpayer, in the words of Saldanha Sanches, "Prior payment of the tax is required, with subsequent reimbursement of the amount indebted if it comes to win the dispute it has with the tax administration, acquiring, in this case, the right to receive compensatory interest"[7]. On the other hand, as is well known, the taxpayer may also avoid the institution of execution by providing guarantees in accordance with article 169 of the Code of Tax Procedure and Process (with the consequent right to indemnification should the same be considered indebted in accordance with article 53 of the General Tax Law) or obtaining its dispensation should it meet the requirements for that purpose, in accordance with articles 52, No. 4 of the General Tax Law and 170 of the CPPT.

Thus, even if the arbitral tribunal had condemnatory competence for the claim in question, the claim could not but be dismissed since the costs in question do not derive from the acts declared illegal but rather from the fact that the Claimant did not request suspension of execution, nor did it make payment within the legal period.

Accordingly, this claim of the Claimant is dismissed.

IV – Decision

Thus, the arbitral tribunal decides:

– That the impugnation is sustained, declaring the illegality and consequent annulment of all the assessments in question.

– That the claim for payment of compensatory interest is totally sustained;

– Condemn the Tax and Customs Authority to annul the assessments mentioned above and, consequently, to refund to the claimant the identified amounts paid with compensatory interest at the legal supplemental rate for civil debts, in accordance with articles 35, No. 10, and 43, Nos. 1 and 5, of the LGT, article 61 of the CPPT, article 559 of the Civil Code and Order No. 291/2003, of 8 April (or any subsequent decree(s)), from the date of payment by the claimant until the date of processing of the credit note, in which they are included (article 61, No. 5, of the CPPT);

– That the claim for condemnation of the Respondent to pay the costs borne by the Claimant with respect to the executive proceedings is dismissed.

Value of the action: €37,174.75 (thirty-seven thousand, one hundred and seventy-four euros and seventy-five cents) in accordance with the provisions of article 315, No. 2, of the CPC and 97-A, No. 1, item a), of the CPPT and 3, No. 2, of the Regulation of Costs in Arbitration Proceedings.

Costs borne by the Respondent, in the amount of €1,836.00 (one thousand eight hundred and thirty-six euros) in accordance with No. 4 of article 22 of the LRAT.

Frequently Asked Questions

Automatically Created

What is Verba 28.1 of the Tabela Geral do Imposto do Selo (TGIS) and how does it apply to high-value properties?
Item 28.1 of the General Stamp Tax Table (Verba 28.1 da TGIS) applies an annual Stamp Tax to high-value real estate properties in Portugal. Following reforms introduced by Law 55-A/2012, properties with taxable values exceeding €1,000,000 are subject to progressive rates: 1% for values between €1,000,000 and €2,000,000, and higher rates for greater values. The tax applies to property ownership rights registered with the tax authorities and is calculated based on the registered taxable value (valor patrimonial tributário) as of December 31st of the previous year. For properties held by entities in tax havens or offshore structures, stricter rates apply. The provision targets luxury real estate holdings and applies to both residential and certain commercial properties, with specific exemptions for properties used in business activities meeting certain criteria.
How are independent units of a building assessed for Stamp Tax (Imposto do Selo) under Portuguese tax law?
Independent units of a building are assessed separately for Stamp Tax purposes when they meet the legal criteria for autonomous use under Portuguese law. Each fraction (fração autónoma) must be independently registered with distinct identification, possess separate utility connections, and have physical characteristics enabling independent occupation. The Tax Authority calculates Stamp Tax individually for each unit based on its registered taxable value at the Finanças. When multiple units within the same building are owned by the same taxpayer, the critical question becomes whether each unit is assessed separately or collectively. In Process 494/2014-T, nine property units each valued around €280,000-€285,000 were individually assessed under Item 28.1 TGIS. The case questioned whether units below the €1,000,000 individual threshold should be taxed when their aggregate value exceeds this limit, raising important issues about the unit of taxation for buildings with multiple independent fractions under common ownership.
Can property owners challenge Stamp Tax liquidations on individually valued property fractions through CAAD arbitration?
Yes, property owners can challenge Stamp Tax assessments on individually valued property fractions through the Administrative Arbitration Center (CAAD), as demonstrated in Process 494/2014-T. The claimant successfully initiated arbitration proceedings under the Legal Regime for Arbitration in Tax Matters (RJAT - Decree-Law 10/2011) to contest 19 separate Stamp Tax liquidations totaling over €53,000. CAAD arbitration provides an efficient alternative to judicial courts for resolving tax disputes, offering faster resolution (typically within 6-12 months), specialized arbitrators with tax law expertise, and lower costs compared to traditional litigation. Taxpayers can challenge both the legality of the assessment (including whether the tax applies to their situation) and computational errors. To initiate arbitration, taxpayers must file a request within 90 days of notification or payment deadline, pay court fees, and present legal arguments. The CAAD's binding decisions can be appealed only on limited procedural grounds, making it an increasingly popular forum for contesting real estate tax assessments, including disputes over whether property fractions should be aggregated or separately assessed for Stamp Tax purposes.
What criteria determine whether parts of a building are considered susceptible to independent use for Stamp Tax purposes?
Portuguese tax law considers parts of a building 'susceptible to independent use' for Stamp Tax purposes based on several criteria established in property law and taxation regulations. Key factors include: (1) Physical autonomy - the unit must have separate access, independent utilities (water, electricity, gas), and structural separation enabling autonomous occupation; (2) Legal registration - the fraction must be registered independently in the property registry (Conservatória do Registo Predial) and tax cadastre with distinct identification; (3) Functional independence - the space must be capable of serving its designated purpose (residential, commercial, etc.) without requiring access to or use of other parts of the building beyond common areas; (4) Separate taxable valuation - each unit receives its own taxable property value (valor patrimonial tributário) from the Tax Authority. In Process 494/2014-T, the dispute centered on whether nine units meeting these criteria should be assessed individually for Item 28.1 TGIS purposes even when each fell below the €1,000,000 threshold. The interpretation affects horizontal property arrangements where buildings are divided into autonomous fractions, determining whether Stamp Tax applies to each fraction separately or to the aggregate value when under common ownership.
What was the outcome of CAAD Process 494/2014-T regarding multiple Stamp Tax assessments on property units below the €1,000,000 threshold?
While the complete decision text of CAAD Process 494/2014-T is not fully provided in the excerpt, the case fundamentally addressed whether multiple property units each valued below €1,000,000 (ranging from €280,470 to €285,640) should be individually subject to Stamp Tax under Item 28.1 TGIS. The dispute involved 19 separate tax assessments totaling approximately €53,000 on nine distinct property fractions (1st-5th Right and 2nd-5th Left) within a building structure, plus additional assessments under Law 55-A/2012. The core legal question was whether the Tax Authority could assess Stamp Tax on each independently usable unit below the statutory threshold, or whether common ownership required aggregating values to determine tax liability. The case established important precedent regarding the interpretation of 'property' under Item 28.1 TGIS - specifically whether the taxable unit is each autonomous fraction or the collective holding. This arbitration highlights tensions between literal application of the €1,000,000 threshold to individual registered units versus purposive interpretation considering economic substance of unified ownership, with significant implications for estate planning, property holding structures, and tax liability calculations for owners of multiple building fractions.
