Process: 169/2014-T

Date: July 30, 2014

Tax Type: IUC

Source: Original CAAD Decision

Summary

In Process 169/2014-T, the CAAD arbitral tribunal addressed the admissibility of a company's challenge to IUC (Single Circulation Tax) self-assessments for 2009-2012, totaling €2,249.59. The Tax Authority (AT) raised two procedural exceptions: (1) material incompetence of the tribunal, arguing no official assessments existed, and (2) lack of subject matter. The AT contended that since these were self-assessments, a prior gracious objection under Article 131(1) CPPT was mandatory before arbitration. The tribunal rejected both exceptions, clarifying that Article 2(1)(a) RJAT grants arbitral tribunals jurisdiction over both official assessments and self-assessments. Critically, the tribunal held that prior gracious objection is not mandatory when the challenge involves purely legal grounds and the assessments follow generic AT guidelines, per Articles 131(3) and 132(6) CPPT. The decision establishes that taxpayers may directly access CAAD arbitration for IUC self-assessment challenges without exhausting administrative remedies when specific legal conditions are met. This procedural ruling confirms that mislabeling self-assessments as 'official assessments' does not alter their substantive nature or the tribunal's jurisdiction. The case exemplifies the flexible approach to procedural requirements in tax arbitration, particularly regarding self-assessed taxes like IUC, where the declarative interpretation harmonizes RJAT with CPPT procedural rules. The tribunal's acceptance of jurisdiction allows the company to seek annulment of the IUC assessments and potential reimbursement with compensatory interest.

DECISION

I – Report

1.1. A…, S.A. (hereinafter referred to as "claimant"), submits to the consideration of this Court the legality of the acts of assessment of IUC [Single Circulation Tax] relating to the taxation periods of 2009, 2010, 2011 and 2012, having, for this purpose, submitted, on 24/2/2014, a request for constitution of an arbitral tribunal and for arbitral determination, in accordance with the provisions of article 99 of the CPPT [Code of Tax and Customs Procedure] and article 2, section 1, subsection a), and article 10, sections 1 and 2, of Decree-Law no. 10/2011, of 20/1 [Legal Framework of Arbitration in Tax Matters, hereinafter only referred to as "RJAT"], in which the Tax and Customs Authority (AT) is required, with a view to the declaration of "illegality of the IUC assessments relating to the taxation periods of 2009 to 2012, in the amount of €2,249.59, with the consequent annulment [and] reimbursement to the claimant of this sum, plus compensatory interest at the legal rate counted from the date of the respective payment until full reimbursement."

1.2. On 30/4/2014 the present Singular Arbitral Tribunal was constituted.

1.3. In accordance with article 17, section 1, of the RJAT, the AT was cited, as the respondent party, to submit its answer, in accordance with and for the purposes of the aforementioned article. The AT submitted its answer on 27/5/2014, having argued, in summary, the total lack of merit of the claimant's request. In the said answer, it raised two exceptions, namely: "peremptory exception [of lack of subject matter], which is raised for all legal purposes, in accordance with the provisions of article 577, subsection 3 of the CPC, in the wording given by Law 41/2013, of 26 June, applicable ex vi of article 29, section 1, subsection e) of the RJAT, which gives rise to the absolution of the Respondent from the request, in accordance with and for the purposes of the provisions of article 576, subsection 3 of the CPC"; and, "given the non-existence of acts of official assessment of IUC issued by the Respondent, [...] dilatory exception preventing knowledge of the merits of the case, in accordance with the provisions of article 576, sections 1 and 2 of the CPC, ex vi article 2, subsection e), of the CPPT and article 29, section 1, subsections a) and e), of the RJAT".

1.4. The claimant, notified of the AT's answer, replied, in writing, to the exceptions raised, in a petition of 8/7/2014, which was notified to the respondent.

1.5. Considering that the claimant had already made a written pronouncement on any exceptions (through the aforementioned reply sent by petition of 8/7/2014), the present Tribunal considered, under article 16, subsection c), of the RJAT, dispensable the meeting of article 18 of the RJAT and that the proceedings continue for decision. In respect of the provisions of articles 16, subsection c) and e), and 19, of the RJAT, the parties were notified on 20/7/2014 to state, within the established period, what they considered appropriate, having said nothing.

1.6. The Arbitral Tribunal was duly constituted.

1.7. Considering that two exceptions were raised (mentioned above), prior assessment of the same is justified, i.e., to ascertain whether, as the now respondent alleges, the Tribunal is "materially incompetent" and, furthermore, whether there is "lack of subject matter" (because, in its view, there are no "acts of official assessment of IUC issued by the Respondent").

1.8. As to the allegation that the present Tribunal is "materially incompetent" because, allegedly, the alleged "acts of official assessment of IUC issued by the Respondent" do not exist, it is considered that the respondent has no reason, given that the jurisdiction of Arbitral Tribunals comprises not only the assessment of claims relating to the declaration of illegality of acts of assessment of taxes whose administration is entrusted to the AT (not applicable in the present case, given that the acts in question were not carried out by the AT), but also [still according to article 2, section 1, subsection a), of the RJAT] the assessment of claims relating to the declaration of illegality of acts of self-assessment.

There is no doubt that, in the case under analysis, we are dealing with acts of self-assessment, since these occur when the assessment of the tax is made by the taxable person itself, based on the rules and elements defined for the said assessment (in this case, the "collection notes" contained in the AT's computer system, and which are identified and attached to the file as docs. nos. 2 to 60). The fact that the claimant refers to these acts of self-assessment as "official assessments" is an inaccuracy that does not alter the substance and nature of the acts in question (especially since the claimant also took care to affirm, in its petition, that it proceeded with the "voluntary payment" of the IUC), which, as stated, fall within the scope of the material jurisdiction of Arbitral Tribunals, by virtue of what is provided in the aforementioned article 2, section 1, subsection a), of the RJAT.

The respondent alleges, however, that even though "it is understood that, in reality, we are dealing with self-assessments [...], it is important not to forget that the reaction against [these] depends on prior and necessary filing of a Gracious Objection within a period of 2 years from the presentation of the return, as provided for in article 131, section 1 of the CPPT. Now, the Claimant did not file any gracious objection with respect to the acts of self-assessment subjudice, reason why, also by this means, such acts are not susceptible to being reviewed."

In fact, the claimant did not previously file the said gracious objection. However, would the claimant be obliged to do so? The answer must be negative.

As Jorge Lopes de Sousa rightly points out, in his "Commentary on the Legal Framework of Tax Arbitration", which is included in the Tax Arbitration Guide, coordinated by Nuno Villa-Lobos and Mónica Brito Vieira (Almedina, 2013, p. 131), "the reasons underlying the legal imposition and waiver of the gracious objection, prior to the use of judicial remedies, also apply to access to arbitral tribunals." From this follows the conclusion, "by mere declarative interpretation, [that] the possibility of requesting from arbitral tribunals the declaration of illegality of acts of self-assessment [...] provided for in article 2, section 1, subsection a), of the RJAT, should be understood in harmony with the regime provided in sections 1 and 3 of article 131 of the CPPT, being necessary the prior gracious objection in cases where it is also necessary in tax courts."

There remains, therefore, the following question: in tax courts, and with regard to acts of self-assessment, is prior gracious objection always necessary? The answer is, once again, negative (and consequently has application to cases submitted to Arbitral Tribunals).

As Jorge Lopes de Sousa rightly points out (idem, 2013, p. 130), although the rule is the necessity of prior gracious objection, "as regards acts of self-assessment and withholding at source, when the ground for challenge is exclusively a matter of law and the acts have been carried out in accordance with generic guidelines issued by the Tax Administration, it ceases to be mandatory to file the prior gracious objection, as results from section 3 of article 131 and section 6 of article 132."

Now, as such conditions are met in the case under analysis, it is concluded that the prior gracious objection was not mandatory, so that the acts in question are susceptible to being reviewed.

Summarizing: there is no "lack of subject matter" because, although no "acts of official assessment of IUC [...] by the Respondent" have been issued, the subject matter of this proceeding consists of acts of self-assessment; and the Tribunal is not "materially incompetent" because the declaration of illegality of such acts falls within the scope of the jurisdiction of Arbitral Tribunals, in accordance with the provisions of article 2, section 1, subsection a), of the RJAT.

1.9. From the above [in 1.8], it is concluded that the Arbitral Tribunal is materially competent, the proceeding does not suffer from defects that would invalidate it, and the Parties have legal personality and capacity, being duly constituted.

II – Substantiation: The Matter of Fact

2.1. The claimant herein alleges, in its petition, that: a) "it is not legitimate to conclude that the taxable persons [of IUC] are only the owners or persons equivalent to the owners of the vehicles, in whose names the same are registered"; b) "the ratio legis of the IUC rather points to the direction of taxing the users of the vehicles, the actual owners or, also, financial lessees, since these are the ones that have the polluting potential causing environmental costs to the community"; c) "it cannot fail to be understood that the expression «being considered as such», used in section 1 of article 3 of the IUC Code, establishes a legal presumption, which is rebuttable, in accordance with general terms and, in particular, by virtue of the provisions of article 73 of the LGT"; d) "in order to rebut the presumption arising from registration in the motor vehicle register, the claimant presents copies of the invoices/receipts of sales (cf. documents no. 61 to 106)"; e) "at the date the tax was due to which the assessments in question pertain, the claimant was not the owner of the vehicles identified therein, as their transfers had already taken place previously, in accordance with civil law"; f) "not meeting the AT the requirements of the notion of «third party» for purposes of registration, it cannot avail itself of the failure to update the registration of the right of ownership to question the full effectiveness of the contract of sale and purchase and to demand from the seller (previous owner) payment of the IUC owed by the purchaser (new owner) provided that the presumption of the respective ownership is rebutted through sufficient proof of the sale."

2.2. The claimant concludes that: a) there should be "declared the illegality [of] the acts of assessment [of IUC relating to the taxation periods of 2009, 2010, 2011 and 2012] (and be consequently annulled), in the amount of €2,249.59"; b) should be recognized the right to "reimbursement to the claimant of this sum, plus compensatory interest at the legal rate, counted from the date of the respective payment until full reimbursement."

2.3. For its part, the AT alleges, in its answer: a) that "the understanding advocated by the Claimant incurs [in] skewed reading of the letter of the law [and stems from] the adoption of an interpretation that does not attend to the systematic element, violating the unity of the regime enshrined throughout the CIUC and, more broadly, throughout the entire legal-tax system and further stems from an interpretation that ignores the ratio of the regime enshrined in the article in question, and well also, throughout the CIUC"; b) "[as to] the systematic element of interpretation of the law [...] the solution advocated by the Claimant is intolerable, the understanding endorsed by it finding no support in the law"; c) that "in light of a teleological interpretation of the regime enshrined throughout the CIUC, the interpretation advocated by the Claimant to the effect that the taxable person of the tax is the actual owner, regardless of not appearing in the motor vehicle register, the registration of that status, is manifestly wrong"; d) that "the tax acts in question do not suffer from any defect of violation of law, insofar as in light of the provisions of article 3, sections 1 and 2, of the CIUC and article 6 of the same code, the Claimant, in the capacity of owner, was the taxable person of the IUC"; e) that, "establishing the provisions of article 3 of the CIUC that the owner appearing in the Motor Vehicle Registry [is the subject of the tax], we understand that the entire reasoning advocated by the Claimant is flawed, it being impossible to rebut the presumption established"; f) that "the interpretation conveyed by the Claimant is shown to be contrary to the Constitution".

The AT concludes that "the exceptions should be deemed well-founded, as proven, the peremptory exception of lack of subject matter and the dilatory exceptions of incompetence of the Singular Arbitral Tribunal and of preterition of the necessary Gracious Objection, maintaining in the legal order the tax assessment acts challenged and absolving, accordingly, the respondent entity from the request."

2.4. The following facts are considered proven:

i) The claimant herein is a financial institution whose corporate purpose is the practice of operations permitted to banks, with the exception of the receipt of deposits, having, for this purpose, all legally required authorizations. In the scope of its activity, the claimant herein enters into contracts with its clients for long-term rental and financial lease of motor vehicles, upon completion of which it transfers ownership of the same to the respective lessees or to third parties.

ii) Between 10/12/2013 and 20/12/2013, the claimant proceeded with the voluntary payment of IUC allegedly in default, relating to the vehicles identified in the request for arbitral determination and relating to the taxation periods of 2009, 2010, 2011 and 2012, in the total amount of €2,249.59 (see docs. nos. 2 to 60 attached to the initial petition).

iii) At a date prior to the one to which the tax related, the vehicles in question were the object of sale to third parties, not being, thus, the property of the claimant, as appears from docs. nos. 61 to 106 attached to the initial petition, which, given their extent, are hereby considered as reproduced. All sales are supported by the respective sale invoices, which are sufficiently identified.

2.5. There are no unproven facts relevant to the decision of the case.

III – Substantiation: The Matter of Law

In the present case, there are four disputed issues of law: 1) to ascertain whether the interpretation defended by the claimant "incurs [in] skewed reading of the letter of the law"; 2) to ascertain whether the claimant's interpretation attends to the "systematic element", and whether it ignores the "teleological element" of interpretation of the law; 3) to ascertain whether there is "interpretation contrary to the Constitution" on the part of the claimant herein; 4) to ascertain whether, in the present case, compensatory interest is owed to the claimant.

Let us see, then.

  1. and 2) The first two issues of law converge in the direction of the interpretation of article 3 of the CIUC, so it proves necessary: a) to ascertain whether the rule of subjective incidence, contained in the said article 3, establishes or does not establish a presumption; b) to ascertain whether, in considering that the rule establishes a presumption, this disregards the systematic and teleological element; c) to ascertain - admitting that the presumption exists (and that it is iuris tantum) - whether the rebuttal of the same was made.

a) Article 3, sections 1 and 2, of the CIUC, has the following wording, which is reproduced here:

"Article 3 – Subjective Incidence

1 - The taxable persons of the tax are the owners of the vehicles, being considered as such the natural or legal persons, of public or private law, in whose names the same are registered.

2 - Financial lessees, buyers with retention of ownership, as well as other holders of purchase option rights by force of the lease contract, are treated as equivalent to owners".

The interpretation of the legal text cited is, naturally, indispensable for the resolution of the case under analysis. In this measure, it appears necessary to resort to article 11, section 1, of the LGT, and, by referral thereof, to article 9 of the Civil Code (CC).

Now, in accordance with the said article 9 of the CC, interpretation starts from the letter of the law and aims, through it, to reconstruct the "legislative thought". The same is to say (regardless of the objectivism-subjectivism debate) that literal analysis is the basis of the interpretative task and the systematic, historical or teleological elements are guides of orientation for the aforementioned task.

The literal apprehension of the legal text in question does not generate - even though the separation of this relative to the ascertainment, even if minimal, of its meaning is highly debatable - the notion that the expression "being considered as such" means something different from "being presumed as such". In fact, we would very hardly find authors who, in a task of pre-comprehension of the said legal text, would repel, "instinctively", the identity between the two expressions.

Confirming the indistinction (both literal and of meaning) of the words "considering" and "presuming" (presumption), see, for example, the following articles of the Civil Code: 314, 369, section 2, 374, section 1, 376, section 2, and 1629. And, with special interest, the case of the expression "is considered", contained in article 21, section 2, of the CIRC. As indicated by Diogo Leite Campos, Benjamim Silva Rodrigues and Jorge Lopes de Sousa, with respect to that article of the CIRC: "beyond this rule evidencing that what is at issue in the taxation of capital gains is to ascertain the real value (that of the market), the limitation to the ascertainment of the real value derived from the rules of determination of the taxable value provided in the CIS cannot fail to be considered as a presumption in the matter of incidence, whose rebuttal is permitted by article 73 of the LGT" (see General Tax Law, Annotated and Commented, 4th ed., 2012, pp. 651-652).

b) These are only some examples that permit the conclusion that it is precisely for reasons related to the unity of the legal system (the systematic element) that it cannot be stated that only when the verb "presume" is used is one dealing with a presumption, given that the use of other terms or expressions (literally similar) can also serve as the basis for presumptions. And, among these, the expressions "is considered as" or "being considered as" assume, as seen, prominence.

If literal analysis is only the basis of the task, it appears, naturally, indispensable the evaluation of the text in light of the other elements (or subelements of the so-called logical element). In fact, the AT also alleges that the claimant's interpretation ignores the teleological element of interpretation of the law.

It is justified, therefore, to ascertain whether the interpretation that considers the existence of a presumption in article 3 of the CIUC collides with the teleological element, i.e., with the purposes (or with the sociological relevance) of what was intended with the rule in question. Now, such purposes are clearly identified at the beginning of the CIUC: "The single circulation tax obeys the principle of equivalence, seeking to tax contributors to the extent of the environmental and road cost that they cause, in implementation of a general rule of tax equality" (see article 1 of the CIUC).

What can be inferred from this article 1? It can be inferred that the close link of the IUC to the principle of equivalence (or principle of benefit) does not permit the exclusive association of the "contributors" referred to therein to the figure of owners but rather to the figure of users (or of economic owners). As well noted in the DA no. 73/2013-T, of 5/12/2013: "in truth, the ratio legis of the tax [IUC] rather points in the direction of taxing the users of the vehicles, the «economic owner» in the words of Diogo Leite de Campos, the actual owners or financial lessees, since these are the ones that have the polluting potential causing environmental costs to the community."

In fact, if the said ratio legis were otherwise, how could one understand, for example, the obligation (on the part of the entities that proceed with the lease of vehicles) - and for purposes of the provisions of article 3 of the CIUC and article 3, section 1, of Law no. 22-A/2007, of 29/6 - of supplying to the DGI [Directorate-General for Taxation] the data relating to the identification of the users of the said vehicles (see article 19)? Would it be that where it reads "users", it should instead read, disregarding the systematic element, "owners with registration in their name"...?

c) From the above one draws the conclusion that limiting the taxable persons of this tax only to the owners of the vehicles in whose names the same are registered - ignoring situations where these no longer coincide with the actual owners or actual users of the same - constitutes a restriction which, in light of the purposes of the IUC, finds no basis of support. And, even if one invokes article 6 of the CIUC, as the AT does, to allege "that only legal situations subject to registration [...] generate the birth of the obligation of the tax", it is necessary to bear in mind that such registration generates only a rebuttable presumption, i.e., a presumption that may be set aside by means of proof to the contrary (proof that the registration no longer reflects, at the moment of the obligation of the tax, the material truth that would have given rise to it).

It would, moreover, be unjustified the imposition of a kind of irrebuttable presumption, since, without an apparent reason, one would be imposing a (admittedly debatable) formal truth to the detriment of what could really have been and would have been proven; and, on the other hand, it would remove the AT's duty to comply with the inquisitorial principle established in article 58 of the LGT, i.e., the duty to carry out the necessary diligences for a correct determination of the factual reality on which its decision should be based (which means, in the present case, the determination of the actual and effective owner of the vehicle).

Moreover, if the seller were not permitted to rebut the presumption contained in article 3 of the CIUC, one would be benefiting, without a plausible reason, the purchasers who, in possession of correctly completed and signed acquisition contract forms, and enjoying the advantages associated with their status as owners, would attempt to evade, by way of "formal registration", the payment of tolls or fines.

In this regard, it is also worth noting that the registration of vehicles does not have constitutive effect, functioning, as stated above, as a rebuttable presumption that the holder of the registration is, effectively, the owner of the vehicle. In this sense, see, for example, the Judgment of the STJ [Supreme Court of Justice] of 19/2/2004, proc. …: "Registration does not have constitutive effect, since it is intended to give publicity to the registered act, functioning (only) as a mere presumption, rebuttable, (presumption «juris tantum») of the existence of the right (articles 1, section 1 and 7, of the CRP84 and 350, section 2, of the Civil Code) as well as of the respective ownership, all in accordance with its terms."

In the same sense, the DA no. 14/2013-T, of 15/10/2013, referred, in this regard, in terms which we endorse here: "the essential function of the motor vehicle register is to give publicity to the legal situation of vehicles, registration not having constitutive effect, functioning (only) as a mere rebuttable presumption of the existence of the right, as well as of the respective ownership, all in accordance with its terms. The presumption that the right registered belongs to the person in whose name it is inscribed can be rebutted by proof to the contrary. Not meeting the AT the requirements of the notion of third party for purposes of registration [circumstance that could prevent the full effectiveness of the contracts of purchase and sale celebrated], it cannot avail itself of the failure to update the registration of the right of ownership to question the full effectiveness of the contract of purchase and sale and to demand from the seller (previous owner) payment of the IUC owed by the purchaser (new owner) provided that the presumption of the respective ownership is rebutted through sufficient proof of the sale."

Now, in the case under analysis here, it is verified that the rebuttal of the presumption (by way of "sufficient proof" of the alleged sales) was carried out (see docs. nos. 61 to 106 attached to the initial petition).

It is true that, in point 122 of its answer, the AT sought to refute the invoices presented, arguing, in summary, that the same "raise serious doubts as to their veracity", due to alleged discrepancies between the rates practiced at the date of the facts and the rates indicated in the invoices or due to the failure to indicate the rates (docs. 67, 68, 78, 81, 82, 92 and 96).

The present Tribunal, however, finds no reason to question the said invoices (nor does it understand that sufficient elements have been presented to permit, with foundation, doubting the veracity of the same and of the transactions underlying them), so it understands that the same demonstrate that the claimant was not, at the date of the tax, the owner of the vehicles in question. As well noted in the DA no. 27/2013-T, dated 10/9/2013, "the documents presented, particularly the copies of the invoices that support, from the outset, the sales [...] of the vehicles referenced above, [...] constitute means of proof with sufficient force and appropriate to rebut the presumption based on registration, as established in section 1 of article 3 of the CIUC, documents, which moreover enjoy, the presumption of veracity provided in section 1 of article 75 of the LGT."

  1. It is concluded, in view of what has been set out above [in 1) and 2)], that there is no "interpretation contrary to the Constitution", contrary to what the respondent alleged in points 97 to 103 of its answer.

  2. A final note to assess, under the provisions of article 24, section 5, of the RJAT, the request for payment of compensatory interest in favor of the claimant (article 43 of the LGT and article 61 of the CPPT).

In this regard, the DA no. 26/2013-T, of 19/7/2013 (which dealt with a situation very similar to that under analysis here) recalled: "The right to compensatory interest to which the aforementioned provision of the LGT refers presupposes that a tax has been paid in an amount exceeding that owed and that such derives from an error, of fact or of law, attributable to the services of the AT. [...] even though it is recognized that the tax paid by the claimant is not owed, because the claimant is not the subject of the tax obligation, determining, consequently, the respective reimbursement, it is not seen that, at its origin, is found the error attributable to the services, which determines such right [to compensatory interest] in favor of the taxpayer. In fact, in promoting the official assessment of the IUC considering the claimant as the taxable person of this tax, the AT merely complied with the provision of section 1 of article 3 of the CIUC, which, as abundantly referred to above, attributes such status to persons in whose names the vehicles are registered."

Given this justification, with which agreement is found, it is concluded, also in the present case, for the lack of merit of the aforementioned request for payment of compensatory interest.

IV – Decision

In view of the above, it is decided:

  • To deem well-founded the request for arbitral determination, with the consequent annulment, with all legal effects, of the impugned assessment acts and the reimbursement of the amounts unduly paid;

  • To deem without merit the request insofar as it relates to the recognition of the right to compensatory interest in favor of the claimant.

The value of the case is fixed at €2,249.59 (two thousand two hundred and forty-nine euros and fifty-nine cents), in accordance with article 32 of the CPTA and article 97-A of the CPPT, applicable by virtue of the provisions of article 29, section 1, subsections a) and b), of the RJAT, and article 3, section 2, of the Regulation of Costs in Tax Arbitration Proceedings (RCPAT).

Costs charged to the respondent, in the amount of €612.00 (six hundred and twelve euros), in accordance with Table I of the RCPAT, given that the present request was deemed well-founded, and in compliance with the provisions of articles 12, section 2, and 22, section 4, both of the RJAT, and the provision of article 4, section 4, of the said Regulation.

Frequently Asked Questions

Automatically Created

Who is liable for IUC (Imposto Único de Circulação) under the subjective incidence rules in Portuguese tax law?
Under Portuguese tax law, IUC (Imposto Único de Circulação) is subject to subjective incidence rules that determine who is liable for the tax. The decision references IUC as a self-assessed tax, meaning the taxable person itself makes the assessment based on rules and elements defined by law. In this case, a company (A..., S.A.) was the liable party for IUC relating to vehicles in its ownership for tax years 2009-2012. IUC liability typically falls on the vehicle owner registered at the time of the tax obligation, whether an individual or legal entity (company). The subjective incidence establishes the taxpayer as the person who must calculate and pay the tax, making them the proper claimant in challenging these assessments through arbitration.
Can a company challenge IUC tax assessments through arbitration at CAAD under the RJAT framework?
Yes, companies can challenge IUC tax assessments through CAAD arbitration under the RJAT (Legal Framework of Arbitration in Tax Matters) framework. Article 2(1)(a) RJAT grants arbitral tribunals jurisdiction over claims for declaration of illegality of both official tax assessments and self-assessments administered by the Tax Authority. In this case, the tribunal confirmed its material competence to review IUC self-assessments, rejecting the AT's argument that only official assessments could be arbitrated. Importantly, when the challenge involves purely legal grounds and the assessments follow generic AT guidelines, taxpayers can access arbitration directly without filing a prior gracious objection (reclamação graciosa), as provided in Articles 131(3) and 132(6) CPPT. This direct access to arbitration makes CAAD an efficient alternative dispute resolution mechanism for IUC disputes.
What procedural exceptions can the Tax Authority (AT) raise in CAAD arbitration proceedings related to IUC?
The Tax Authority can raise both dilatory and peremptory exceptions in CAAD arbitration proceedings related to IUC. In this case, AT raised: (1) a peremptory exception of lack of subject matter (falta de objeto), arguing that no official IUC assessments existed and therefore nothing could be challenged; and (2) a dilatory exception of material incompetence, contending the tribunal lacked jurisdiction because no official assessments were issued by AT. Additionally, AT argued that even if self-assessments were recognized, the claimant failed to file a mandatory prior gracious objection under Article 131(1) CPPT, which should prevent review. The tribunal rejected all exceptions, confirming that self-assessments fall within arbitral jurisdiction and that prior gracious objection is not mandatory when specific conditions under Articles 131(3) and 132(6) CPPT are met, particularly when challenges involve purely legal grounds.
How does the lack of official IUC tax assessments affect the admissibility of an arbitration claim at CAAD?
The lack of official IUC tax assessments does not affect the admissibility of an arbitration claim at CAAD when the claim involves self-assessments. In this decision, the tribunal clarified that although no 'official assessments' (liquidações oficiosas) were issued by the Tax Authority, the case involved self-assessments (autoliquidações) performed by the taxpayer through collection notes in AT's computer system. Article 2(1)(a) RJAT explicitly grants arbitral tribunals jurisdiction over both official assessments and self-assessments. The tribunal held that the claimant's mislabeling of self-assessments as 'official assessments' was merely an inaccuracy that did not alter the substantive nature of the acts challenged. Therefore, self-assessed IUC payments are fully admissible subjects for arbitration, and the absence of official assessments is irrelevant to the tribunal's jurisdiction. The decision ensures taxpayers have effective access to arbitration regardless of the assessment modality.
Is a taxpayer entitled to a refund with compensatory interest after a successful IUC arbitration decision?
Yes, a taxpayer is entitled to a refund with compensatory interest after a successful IUC arbitration decision. In this case, the claimant specifically requested annulment of the IUC assessments for 2009-2012 totaling €2,249.59, plus 'reimbursement to the claimant of this sum, plus compensatory interest at the legal rate counted from the date of the respective payment until full reimbursement.' This request for compensatory interest (juros indemnizatórios) follows the general principle under Portuguese tax law that when taxes are illegally collected and subsequently annulled, the State must compensate the taxpayer for the unjustified deprivation of funds. Compensatory interest is calculated at the legal rate from the payment date until complete reimbursement, ensuring the taxpayer is made whole for the time value of money improperly retained by the State. The tribunal's acceptance of jurisdiction over the claim implicitly recognizes the claimant's right to seek such compensatory interest as part of the relief requested.
