Summary

This arbitral tribunal case (Process 301/2013-T) concerns the applicability of Verba 28 of the General Stamp Tax Table (TGIS) to urban properties classified as building land. The claimant, an architecture company, challenged stamp tax assessments totaling €34,646.18 on three high-value urban properties (each with tax values exceeding €1 million) classified as building land for construction. The central legal issue is whether Verba 28.1, which imposes 1% stamp tax on properties with 'housing designation' (afetação habitacional), applies to undeveloped building land or only to built/inhabited residential properties. The claimant argued that building land lacks housing designation since no dwellings exist, making the tax rule inapplicable. Additionally, the claimant contended that simultaneous application of stamp tax and IMI (Municipal Property Tax) on the same properties constitutes prohibited double taxation. The Tax Authority countered that the legislative intent behind 'housing designation' encompasses land suitable for construction with housing potential, not merely existing built structures, as evidenced by the properties' tax valuations. The Authority justified the tax as targeting manifestations of higher patrimonial wealth during the economic crisis, applying the principle of 'social equity in austerity,' and maintained that stamp tax and IMI involve distinct taxable events without duplication. The arbitral tribunal initiated constitutional analysis examining whether Verba 28 violates equality principles and protection of legitimate expectations. The case represents significant jurisprudence on interpreting stamp tax provisions affecting high-value real estate holdings, establishing important precedents for distinguishing between actual housing use versus potential housing designation for tax purposes, and clarifying the boundaries between overlapping property tax regimes.

I – Introduction

  1. On December 23, 2013, A... – ARCHITECTURE OF CITY, LTD, a commercial company with quota capital with Tax Identification Number ..., with registered office at Avenue ..., ..., hereinafter the Claimant, submitted a request for the constitution of a singular arbitral tribunal, in accordance with the combined provisions of arts. 2º and 10º of Decree-Law no. 10/2011, of January 20 (Legal Framework for Arbitration in Tax Matters, hereinafter only designated as RJAT), in which the Tax and Customs Authority is named as Respondent, hereinafter the Respondent or the AT.

  2. The request for a singular arbitral tribunal was accepted by His Excellency the President of CAAD on December 26, 2013.

On the following day, the Deontological Council appointed Prof. Doctor Jorge Bacelar Gouveia as arbitrator of the Singular Arbitral Tribunal, who communicated his acceptance of the position, an appointment that was not contested by the parties, with the SAT being constituted on February 25, 2014.

By agreement between the parties, the meeting provided for by art. 18º of the RJAT was dispensed with.

The six-month period for the delivery of the SAT's decision was extended until July 31, 2014.

II – Characterization of the Dispute

  1. With regard to the characterization of the dispute, the Claimant requested from the SAT the declaration of nullity by illegality – with restitution of amounts unduly paid, in addition to the necessary compensatory interest – of three tax assessments imposing stamp duty relating to 2012, concerning urban properties registered in the property register under urban articles ..., ... and ... of the parish ... – …, municipality of …, now corresponding to articles ..., ... and ... of the parish ... – Union of Parishes of … and …, … and …, in the amount of:
  • 11,611.91 euros for the property ..., pursuant to official communication 2013 ... of the Respondent;
  • 12,376.54 euros for the property …, pursuant to official communication 2013 ... of the Respondent;
  • 10,657.73 euros for the property …, pursuant to official communication 2013 ... of the Respondent.

The Claimant administratively challenged the aforementioned assessments, and the Respondent denied relief, after which the Claimant proceeded to make voluntary payment in the total amount of 34,646.18 euros.

The grounds invoked for the request relate to the fact that the provision of item no. 28 of the General Table of Stamp Duty cannot be applied to such urban properties as they are "land for construction," not falling within the provision of that tax rule inasmuch as they do not possess "housing designation," and furthermore those assessments represent double taxation due to the parallel application of IMI.

  1. Notified to contest, the Respondent stated that item no. 28 of the TGIS should be applied and the request should be dismissed, contending that the urban properties in question have housing designation, taking into account that they are suitable for construction, being "land for construction" with that potential, which would even be confirmed by their respective tax value.

The Claimant's argumentation is fundamentally based on the distinction – which the legislator intended to make – between "properties intended for housing" and "properties with housing designation," with the preference for this latter expression intended to signify an expansion of the provision of the tax rule by including building land in it, not merely already built or inhabited land.

It also invokes proportionality and equality of the tax rule in the context of the economic-financial crisis the country is experiencing, thereby justifying the taxation of manifestations of higher patrimonial wealth, based on the orientation dictated by the principle of "social equity in austerity," with there being no duplication of collection as it involves distinct tax facts.

  1. The SAT was duly constituted and is competent.

The parties have standing and legal capacity and are legitimate (arts. 4.º and 10.º, no. 2, of the same statute and art. 1.º of Regulation no. 112-A/2011, of March 22).

The process is free from defects.

A decision is warranted.

III – The Relevant Facts

  1. The relevant factual matter is straightforward and consists in the verification of ownership in favor of the Claimant of the above-identified properties, with the following facts being considered proven:

a) The Claimant A... – ARCHITECTURE OF CITY, LTD, is a commercial company with quota capital, with Tax Identification Number … and with registered office at Avenue …, …;

b) The Claimant is the owner of three urban properties registered in the property register under urban articles ..., ... and ... of the parish ... – …, municipality of …, now corresponding to articles ..., ... and ... of the parish ... – Union of Parishes of … and …, … and …;

c) The Respondent proceeded to make assessments of stamp duty relating to those properties, subsequently paid by the Claimant, in the following amounts: 11,611.91 euros for the property ..., pursuant to official communication 2013 ... of the Respondent; 12,376.54 euros for the property …, pursuant to official communication 2013 ... of the Respondent; 10,657.73 euros for the property …, pursuant to official communication 2013 ... of the Respondent.

The Tribunal's conviction regarding the factual findings was based on the documents submitted by the Claimant and the Respondent and on the positions expressed by the parties regarding the facts alleged by the opposing party, as well as on the absence of contestation of the documents attached to the record.

IV – Applicable Law

A) Preliminary Matters

  1. The present dispute has as its focal aspect the validity and application of item no. 28 of the General Table of Stamp Duty, added by Law no. 55-A/2012, of October 29, combined with the provision of art. 6º, no. 2, al. f) and i), of the same statute.

This new provision establishes that ownership of properties with housing designation with a tax patrimonial value equal to or greater than 1,000,000 euros is subject to stamp duty, in the following exact terms:

"28 – Ownership, usufruct or right of superficies of urban properties whose tax patrimonial value contained in the property register, in accordance with the Code of Municipal Property Tax (CIMI), is equal to or greater than 1,000,000 euros – on the tax patrimonial value used for purposes of IMI:

28.1 – For a property with housing designation – 1%;

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

  1. The Claimant submits its request for a declaration of nullity of the three official assessments of stamp duty on the basis of incorrect subsumption made by the Respondent to the mentioned properties.

However, in our view, the issue should also be analyzed from the perspective of the validity of that rule embodying item no. 28 in the TGIS in light of the Constitution of the Portuguese Republic (CRP), which any tribunal must apply, even an arbitral tribunal, in accordance with art. 204º of the CRP.

B) Grounds of Unconstitutionality and Error in Application of Item No. 28 of the TGIS

  1. From the perspective of applicable law, in the present dispute and in order to obtain acceptance of its request for annulment of the mentioned assessments of stamp duty, an examination of constitutionality is required by force of the supremacy of the Constitution and the duty of the courts to apply it, and the constitutionality of the rule embodying item no. 28 of the TGIS should be questioned in the following terms:

  • unconstitutionality due to violation of the principle of equality; and

  • unconstitutionality due to violation of the principle of protection of confidence.

But the argumentation advanced by the Claimant regarding the factual matter previously established also includes error in the application of the new provision that created item no. 28 of the TGIS, since in its view it would not apply to the properties referred to in the said assessments, which would not meet the concept provided for in that rule.

We shall begin with the arguments relating to the constitutional validity of the rule that created item no. 28 of the TGIS, and then proceed to the assessment of its application to the properties that were considered for purposes of stamp duty assessment.

C) The Invalidity of Item No. 28 due to Violation of the Principle of Equality

  1. Equality is a value and a principle inherent to the paradigm of the Rule of Law that permeates the entire material Portuguese Constitution, which even becomes part of the very idea of Law or of Legal Order as a Legal Cosmos.

The principle of equality is directly stated by the Portuguese constitutional text in its art. 13º, in addition to its evident manifestation in the sphere of the principle of contributory capacity, which expresses a special orientation of equality in tax matters.

Thus, it is important to refer to this central constitutional provision of art. 13º of the CRP:

  • art. 13º, no. 1: "All citizens have the same social dignity and are equal before the law";

  • art. 13º, no. 2: "No one may be privileged, benefited, harmed, deprived of any right or exempted from any duty by reason of ascendancy, sex, race, language, territory of origin, religion, political or ideological convictions, education, economic situation, social condition or sexual orientation".

  1. The same applies to the General Tax Law (LGT), which also formulates the principle of equality in the context of Portuguese tax legislation, as can be seen in its art. 5º:

  • art. 5º, no. 1: "Taxation aims at satisfying the financial needs of the State and other public entities and promotes social justice, equality of opportunity and the necessary corrections of inequalities in the distribution of wealth and income";

  • art. 5º, no. 2: "Taxation respects the principles of generality, equality, legality and material justice".

  1. The principle of equality in a Social State is substantially different from the principle of equality that prevailed during the Liberal State period, involving a whole set of new dimensions and ways of acting to achieve material equality and equality of opportunity.

But in matters of taxation of property – not addressing here the theoretical question of the nature of stamp duty in the contrast between taxes on consumption and taxes on property – the Constitution itself establishes a central orientation in its art. 104º, no. 3: "Taxation of property must contribute to equality among citizens".

In its simplicity, this constitutional provision, specifically established for this type of taxation, exemplifies a principle of tax equality that takes into account the new dimensions of the social principle.

  1. We hold that the provision in question, which added item no. 28 to the TGIS, is affected by material unconstitutionality due to violation of the principle of equality.

It is important to note that the configuration of the tax fact, which distinguishes between various uses and designations of the properties in question, does not appear justified in terms of the purpose of the fiscal measure adopted.

If the concern is the taxation of higher patrimonies, what is the reason why such taxation, in this case of real property of which the taxpayer is the owner, should not tax all such properties in their multiple sub-distinctions?

If one looks carefully, there are several categories of properties that fail to be subject to this new taxation:

  • non-urban properties;

  • urban properties that do not correspond to the specifications of items nos. 28.1 and 28.2.

The rationale for not including all such uses and designations is not apparent, and it is certain that if all of them were included, tax revenue would be greater and would equalize taxpayers on the basis of the same patrimonial value referred to.

Even considering the difference in economic value between rural and urban properties, or within these in their various uses and designations, since the criterion is referred to the patrimonial value under the CIMI, by this mechanism objective assessment of the wealth in question would already have been made, being different according to those different distinctions that are taken into account in the assessment undertaken by the relevant CIMI provisions.

  1. With this differentiation, a perverse revaluation is even introduced into the Portuguese tax system, contrary to the general orientation that may be derived from the CRP, which is that of imposing greater sacrifice on taxpayers who own properties with housing designation to the detriment of other uses or designations that are not as valuable in light of constitutional values and principles, and in that sense it is appropriate to invoke:

  • not only the valorative prominence of the right to housing, provided for in art. 65º of the CRP, which, even being an economic and social right offering legal efficacy inferior to that of rights, freedoms and guarantees, nonetheless has a privileged constitutional place that serves as a benchmark to, at least, avoid discrimination in relation to other uses that do not have the same constitutional importance;

  • but also one cannot forget the projection of the principle of human dignity itself, a guiding principle of the Portuguese constitutional order and stated at the outset in art. 1º of the CRP, which certainly implies special valorization of the uses that citizens pursue in their life spheres, there being here a manifestation of that value in the greater protection that must be accorded to property devoted or designated for housing – which is human housing – than to properties that have other uses or designations.

  1. There is another reason to consider that item no. 28 of the TGIS infringes the principle of tax equality, in this case considering the constitutional prohibition of double taxation in the legal sense, which is also here a double taxation in the economic sense.

Double legal taxation means that the same manifestation of wealth, expressed in the same tax fact, is taxed twice, thereby constituting negative discrimination in relation to other taxpayers whose taxation occurred only once on the same tax fact.

Although without literal expression in the constitutional text, the prohibition of double legal taxation is not only deduced from the principle of contributory capacity, being expressed in Constitutional Criminal Law through the principle non bis in idem.

The most authoritative Portuguese tax doctrine has emphasized this aspect of the principle of equality, as is the case with JOSÉ CASALTA NABAIS: "...in imposing intra-systemic limits, that is, coherence between the various taxes and coherence of the tax system as a whole, the principle in question should be invoked for the solution of problems such as internal double taxation, whether manifested in double taxation (double legal taxation) or in an overlap of taxes (double economic taxation), multiple or plural taxation, which results in the same goods, for example real estate, being subject to various taxes, the conversion of taxes, which materializes in the transformation of income taxes into property taxes by virtue of, for example, the legislator's inertia in the face of the inflation phenomenon, etc." (JOSÉ CASALTA NABAIS, Tax Law, 7th ed., Coimbra, 2012, p. 164).

  1. However, what precisely does this double taxation consist of? It consists in the fact that ownership of real rights is simultaneously taxed under the CIMI and under IS, which falls upon the same reality, which becomes abundantly evident when the terms of the taxation of item no. 28 of the TGIS are referred to the applicable CIMI rules.

We thus have two concurrent taxations with respect to urban properties, to which two taxes apply, each with their own rates:

  • the taxation established in art. 1º of the CIMI; and

  • the taxation established in item no. 28 of the TGIS.

It is not considered a relevant counter-argument that the active subject of the tax legal relationship is different, the State in IS and the municipalities in IMI, since only the position of the passive subject is relevant here.

  1. It does not seem pertinent to defend the result of unconstitutionality the fact that the rule in question establishes a threshold below which equivalent manifestations of wealth, also pertaining to properties with housing designation, remain untaxed, either because they approach the 1,000,000 euro threshold or because in the same taxpayer various properties may accumulate which, together, exceed that threshold, with taxation being assessed property-by-property and not as a global taxation from the perspective of the taxpayer's patrimonial situation.

Obviously the legislator has the necessity of establishing limits in the quantification of taxation, a phenomenon that occurs in many other branches of law, such as the age of majority in Civil Law or speed limits in Road Law.

Although these limits, which always artificially divide the underlying reality to which the rules apply, are not arbitrary and are required by the necessity to regulate situations in life, in addition to the necessity for security that Law also requires, they must be accepted and validated from the perspective of their constitutionality and legality. Now, that is what occurs in the case at hand.

On the other hand, this threshold expresses the definition – within the freedom conferred by the Constitution on the ordinary legislator – of a criterion above which it is considered acceptable to tax more or even to tax at all in the name of a principle of contributory capacity that expresses concern for social justice.

This means that the principle of equality today has inherent to it the admission of negative discrimination against those groups that, earning higher incomes or possessing more valuable patrimonies, may be subject to greater taxation, in two senses:

  • either through progressive taxation, as realized in personal income taxes;

  • or through proportional taxation, in this case only affecting property above 1 million euros.

This provision is not considered unconstitutional due to violation of the principle of contributory capacity.

D) The Violation of the Principle of Protection of Confidence

  1. Since the SAT is obviously subject to the principle of party autonomy, in the sense that the procedural object is necessarily defined by the parties, it is not bound, as regards applicable law, to the legal arguments put forward by the parties.

This means that for the SAT the rule of item no. 28 of the TGIS raises another question of unconstitutionality, due to violation of the principle of protection of confidence, which can and should be assessed.

  1. Although not literally enshrined in the text of the CRP, this principle nonetheless affirms itself in Portuguese constitutional normativity by deduction from the general formulation of the principle of the Rule of Law, referred to in art. 2º of the CRP.

On the other hand, there have been abundant – especially in these recent decisions issued in the context of measures to combat the economic-financial crisis – references and applications that the Constitutional Court has made of it.

The principle of protection of confidence, in general terms, means that public power – or legislative power in particular – is prevented from enacting legal measures whose effects mean a revocation or limitation of interests or expectations of citizens, legitimately constructed through preceding legal regimes, without there being a sufficient rational basis for such action.

  1. One of the specific dimensions of the principle of confidence is that of retroactive application of laws, which is expressly prohibited in a set of cases stated in the constitutional text.

But the operability of this principle is not only connected with retroactivity, nor even with the soft version of retrospective application, which has specific application in Tax Law when faced with periodic taxes.

This principle can also invalidate future changes to legislation, if these present themselves as abrupt, appearing as surprise decisions, with which citizens could not have counted and had the legitimate expectation that they would not arise in the manner in which the legislative decision-maker modeled them.

"The principle of confidence, requiring that the existing regulatory framework not change in a manner that frustrates the expectations generated in citizens about its continuity, implies the prohibition of intolerable retroactivity of laws, as well as the necessity of its future alteration in conformity with expectations that are constitutionally protected" (JORGE BACELAR GOUVEIA, Manual of Constitutional Law, II, 5th ed., Coimbra, 2013, p. 726).

  1. The assessment of the rule of item no. 28 of the TGIS does not raise, in this regard, a problem of retroactivity, nor even a problem of retrospective application, being in fact a single-occurrence tax: the new tax fact is constructed for the future, more precisely, for the day following the entry into force of the rule that creates it.

It does raise, however, a problem of breach in the confidence that should exist between the State-Legislator and the Citizen, who trusted in the stability of tax provisions on stamp duty, having been "caught by surprise" by a legislative measure that entered into force on the day following its publication.

This is a fact that in itself would not have special significance if it were an economically neutral measure or if it were inserted in a legal context in which the prospective effectiveness of legislative acts could be indifferently established between the day following its publication or any other later day.

This is not the case because the placement of the effectiveness of this new rule on the day following its publication deeply disturbs the predictability with which taxpayers had the right to rely on in the configuration of stamp duty, whose tax fact is always assessed on December 31.

Suddenly, there is a substantial change in the relevant date of that tax fact to October 31, not giving taxpayers time to act in light of the new tax provision created. That is the purpose of art. 6º of Law no. 55-A/2012, of October 29.

  1. What is most striking is that this change itself assumes no other rationale than to suddenly capture an increase in revenue, by advancing the tax fact from December 31 to October 31: because for the following year, the year 2013, since the rule of art. 6º applies only to the year 2012, the tax fact again becomes December 31.

One understands why, by the application of the general IMI rule, there would no longer be in the following year any surprise factor. It is not believed that in a State of Law it is legitimate, in terms of protection of confidence, for the legislator to act in this manner.

Such behavior on the part of the tax legislator violates the good faith that the citizen placed in the State, trusting that on its part there would be no surprise measures without adequate rational foundation.

E) The Incorrect Application of the Concept of "Property with Housing Designation" Provided for in Item No. 28 of the TGIS

  1. Even with the conclusion of unconstitutionality of the rule that added item no. 28 to the TGIS, for the reasons set out, it is necessary to assess the other question at hand, which is the application to the assessments made of stamp duty of the concept of "property with housing designation".

The rule in question textually refers to item no. 28.1 of the TGIS as affecting "property with housing designation," but nowhere addresses the explanation of that concept.

  1. Reading the CIMI does not permit finding any provision in which the expression "property with housing designation" is used.

Therein we find the fundamental distinction between urban and rural properties, in addition to the category of mixed properties, then specifying that urban properties may subdivide themselves into various classes, one of which being "residential properties," as established in art. 6º, no. 1, al. a), of the CIMI.

A first distinction removes from art. 4º of Law no. 55-A/2012 properties that are rural, or in mixed properties the part that is not urban, as well as removes the uses or designations of urban properties that are not residential, as occurs with commercial or industrial purposes, in accordance with the various categories provided for in art. 6º, no. 1, als. b) to d), of the CIMI.

  1. Proceeding with that analysis, there remains the need to know whether the housing designation must be effective – that is, to be a property as such licensed – or whether that designation as a normal designation is sufficient, without there being yet a license for use for housing purposes.

It is believed that there are reasons to require an effective and concrete designation, and not merely a potential one, such being the fundamental meaning to be obtained from the expression "property with housing designation," which is understood to incorporate an effective purpose, because already concretized. In this sense, see the argumentation put forward in Decision no. 27/2014 of the Arbitral Tribunal of the CAAD, which we reiterate here.

  1. If this were not so, the legislator would not have had the necessity to alter this normative provision through the new wording given by art. 194º of Law no. 83-C/2013, of December 31, which approved the State Budget for 2014, in which the reference to "building land" is added: "28.1. For a residential property or for building land whose building, authorized or intended, is for housing, in accordance with the provisions of the IMI Code – 1%".

Even though not being an interpretive provision, not applying retroactively (which, if it were to happen, would raise the greatest reservations from the perspective of protection of taxpayers' guarantees…), here is a provision revealing that the new reality now contained in it was not encompassed by its earlier formulation: precisely "building land," which is not even mentioned at any point in the parliamentary discussion that the 2012 statute provoked at the time of its approval.

  1. In light of the foregoing, we consider that the indicated properties, being "land for construction," do not offer housing designation due to lacking that referred to concretization with respect to their use, and therefore do not fall within the legal concept of property of item no. 28 of the TGIS.

V – Decision

  1. For the foregoing reasons, the Singular Arbitral Tribunal decides:

a) To declare the illegality, with its consequent annulment, of the assessments of stamp duty – three tax assessments imposing stamp duty relating to 2012 concerning urban properties held by the Claimant, registered in the property register under urban articles ..., ... and ... of the parish ... – …, municipality of …, now corresponding to articles ..., ... and ... of the parish ... – Union of Parishes of … and …, … and …, in the total amount of € 34,646.18 – 11,611.91 euros for the property ..., pursuant to official communication 2013 ... of the Respondent, 12,376.54 euros for the property …, pursuant to official communication 2013 ... of the Respondent, and 10,657.73 euros for the property …, pursuant to official communication 2013 ... of the Respondent – as the same, being concerning "land for construction," do not fall within the normative provision of item no. 28 of the General Table of Stamp Duty, with the consequent restitution of the amounts thus unduly paid by the Claimant;

b) Not to apply the rule of item no. 28 of the General Table of Stamp Duty, as it infringes the principle of equality and the principle of protection of confidence enshrined in the Constitution of the Republic, in obedience to the rule enshrined in art. 204º of the CRP, the assessments of stamp duty made remaining without legal basis;

c) To determine payment to the Claimant by the Respondent of applicable compensatory interest, in accordance with article 43.º of the General Tax Law, in the sequence of the invalidation of the assessments of stamp duty that were made by the Respondent.

Amount in dispute: € 34,646.18 (thirty-four thousand, six hundred and forty-six euros and 18 cents).

Costs awarded against the Respondent, in the amount of € 1,836.00.

Frequently Asked Questions

Automatically Created

Does Verba 28 of the General Stamp Tax Table apply to urban properties classified as building land (terrenos para construção)?
The application of Verba 28 TGIS to building land (terrenos para construção) is the central dispute in this case. The claimant argues that Verba 28 requires actual 'housing designation' which building land lacks, as it contains no built or inhabited structures. The Tax Authority contends that the expression 'properties with housing designation' was intentionally broad to include land suitable for construction with housing potential, not just existing buildings. The Authority argues this interpretation is supported by the properties' tax valuations and the legislative intent to expand the tax base beyond merely built properties. The tribunal's analysis examines whether 'afetação habitacional' requires physical housing or includes land with housing construction potential.
Is housing allocation (afetação habitacional) required for Stamp Tax liability under Verba 28 of the TGIS?
Housing allocation (afetação habitacional) is the critical requirement under Verba 28.1 TGIS for stamp tax liability. The legal interpretation centers on whether this term encompasses only properties currently designated for residential use with existing structures, or extends to vacant building land with potential for future housing construction. The claimant maintains a restrictive interpretation requiring actual housing use or built residential structures. The Tax Authority advocates an expansive interpretation where land zoned and suitable for housing construction possesses 'housing designation' by virtue of its intended purpose and construction potential, regardless of current development status. This interpretive question determines the tax's scope and applicability to undeveloped real estate holdings.
Can Stamp Tax under Verba 28 TGIS and IMI be applied simultaneously without constituting double taxation?
The question of double taxation arises from simultaneous application of Verba 28 stamp tax and IMI (Municipal Property Tax) to the same properties. The claimant argues this constitutes prohibited double taxation on identical tax bases. The Tax Authority responds that these are distinct taxes with different legal foundations and taxable events: IMI is an annual municipal tax on property ownership based on patrimonial value, while stamp tax under Verba 28 is an exceptional levy targeting high-value property holdings as manifestations of wealth capacity. The Authority maintains there is no constitutional prohibition against multiple taxes on property when they serve different purposes and respond to distinct policy objectives, particularly during economic crisis requiring 'social equity in austerity.' The tribunal must determine whether sufficient differentiation exists between these levies.
What is the procedure to challenge Stamp Tax liquidations on high-value properties before CAAD arbitration?
The procedure to challenge stamp tax liquidations on high-value properties involves submitting a request to constitute an arbitral tribunal before CAAD (Centro de Arbitragem Administrativa) under the Legal Framework for Arbitration in Tax Matters (RJAT - Decree-Law 10/2011). The taxpayer must file the request within the legal deadline, identifying the contested tax assessments and legal grounds for annulment. After acceptance, the CAAD President appoints an arbitrator (or tribunal panel), which the parties may contest. The tribunal is constituted once appointments are final. Parties may agree to dispense with preliminary hearings. The tribunal has six months (extendable by agreement) to render a decision. Prior administrative challenge is not mandatory before arbitration. This alternative dispute resolution mechanism provides specialized, expedited resolution of tax disputes outside traditional courts.
Are taxpayers entitled to compensatory interest (juros indemnizatórios) when Stamp Tax liquidations on building land are annulled?
Taxpayers are entitled to compensatory interest (juros indemnizatórios) when stamp tax liquidations are annulled if amounts were paid before the annulment decision. The Legal Framework establishes that when tax assessments are declared null or illegal and the taxpayer made voluntary payment, restitution includes the principal amount plus compensatory interest from the payment date until reimbursement. This compensates taxpayers for loss of use of funds improperly collected. In this case, the claimant specifically requested restitution of €34,646.18 plus compensatory interest. The interest rate and calculation method follow statutory provisions in the General Tax Law (LGT). Entitlement arises automatically upon annulment of assessments where payment preceded the favorable decision, without requiring separate demonstration of damages beyond the improper retention of funds by the Tax Authority.
