Process: 146/2014-T

Date: September 30, 2014

Tax Type: IUC

Source: Original CAAD Decision

Summary

Process 146/2014-T addressed whether a company remained liable for IUC (Imposto Único de Circulação) assessments on vehicles it had allegedly sold or written off before the tax year. The claimant company challenged IUC assessments and compensatory interest, arguing it had transferred ownership prior to the taxable events through sales or total loss. The company contended that Articles 3 and 6 of the IUC Code establish only a rebuttable presumption linking registered ownership to tax liability, which could be overcome by proving actual transfer of ownership. The Tax and Customs Authority defended the assessments on multiple grounds. First, it raised a jurisdictional objection, arguing the CAAD Arbitral Tribunal lacked material competence to review administrative infraction penalties. Substantively, the Authority argued that Article 3(1) uses the term 'deemed' rather than 'presumed,' reflecting a deliberate legislative policy choice to base IUC liability on vehicle registration records rather than actual ownership. The Authority emphasized that Article 6(1) defines the taxable event as ownership 'as attested by registration,' creating a direct link between registration and tax obligation. This system serves principles of legal certainty, administrative efficiency, and taxpayer protection by avoiding the need to investigate factual ownership beyond public records. The Authority noted the claimant failed to comply with mandatory notification requirements under Highway Code Article 118(4) and that sales invoices alone were insufficient proof of ownership transfer. The case highlights the fundamental tension in IUC law between formal registered ownership and actual economic ownership, with significant implications for vehicle taxation policy, administrative efficiency, and taxpayer rights when ownership changes are not properly registered.

Full Decision

CLAIMANT: A..., Ltd

RESPONDENT: Tax and Customs Authority

The Arbitrator Francisco de Carvalho Furtado, appointed by the Deontological Council of the Administrative Arbitration Center (CAAD), to form the Arbitral Tribunal constituted on 22 April 2014, decides as follows:

A) REPORT

  1. On 17 February 2014, A..., Ltd., taxpayer no. …, hereinafter identified as the Claimant, filed a request for arbitral determination, in accordance with the provisions of articles 2, no. 1, paragraph a) and 10 of Decree-Law no. 10/2011, of 20 January (Legal Framework for Arbitration in Tax Matters, hereinafter designated as LFATM), in conjunction with paragraph a) of article 99 and paragraph d) of no. 1 of article 102 of the Tax Procedure and Process Code (TPPC), applicable by virtue of article 10, no. 1, paragraph a), of Decree-Law no. 10/2011, of 20 January.

  2. In the aforementioned request for arbitral determination, the Claimant seeks that the Arbitral Tribunal declare the illegality of the assessment acts for the Single Vehicle Circulation Tax and, likewise, the respective assessment acts for Compensatory Interest, better identified in the case file.

  3. The request for constitution of the arbitral tribunal was accepted on 19 February 2014, by His Excellency the President of the CAAD and was notified to the Tax and Customs Authority (hereinafter identified as the Respondent), on the same date.

  4. The Claimant did not appoint an arbitrator, and therefore, pursuant to the provisions of article 6, no. 1, of the LFATM, the undersigned was appointed by the President of the Deontological Council of the CAAD to serve on the present Sole Arbitral Tribunal, with the appointment having been accepted in accordance with legal provisions. The Tribunal was constituted, in accordance with the provisions of article 11 of the LFATM, on 22 April 2014.

  5. On 3 June 2014, the Respondent filed its Response.

  6. On 1 September 2014, and in accordance with the terms and for the purposes provided in article 18 of the LFATM, the first meeting of the Arbitral Tribunal was held, and minutes thereof were drawn up, which are attached to the case file.

  7. On 17 September 2014, the witness called by the Claimant was examined, after which oral arguments were presented by both the Claimant and the Respondent.

The Claimant supports its claim, in summary, as follows:

a) The Claimant was the owner of various motor vehicles better identified in article 4 of the Initial Request;

b) Subsequently, the Claimant was notified of assessment acts for the Single Vehicle Circulation Tax (SVCT) concerning each of the aforementioned vehicles;

c) The Claimant was also notified of penalties applied in the administrative infraction proceedings identified in the Initial Request;

d) In the year to which each of the SVCT assessments pertains, the Claimant was no longer the owner of the vehicles, either by alienation or by total loss due to accident;

e) From the combination of articles 3 and 6 of the SVCT Code, it results that the taxable event of this tax is constituted by ownership of the vehicle, and such person is responsible for payment of the tax;

f) The aforementioned legal provisions constitute merely a rebuttable presumption;

g) The Claimant alienated the vehicles on a date prior to the date of the taxable event;

h) The assessment acts are not adequately reasoned;

i) The Claimant's vehicles belong to category "D" and not to category "C", as "taxation by category 'C' can never be considered lawful, as occurred with respect to vehicles ..-..-..; ..-..-..; ..-..-..; ..-..-..; ..-..-..; and ..-..-.."

In its Response, the Respondent, invoked, in summary, the following:

a) The Arbitral Tribunal lacks competence to review the legality of penalties applied in administrative infraction proceedings;

b) The Claimant failed to comply with the obligation to notify the sale to the IMTT, established by article 118, no. 4, of the Highway Code;

c) The interpretation and application that the Claimant seeks to assert does not take into account the systematic element, violating the unity of the regime established throughout the SVCT;

d) The legislator established in article 3, no. 1, of the SVCT Code who the passive subjects of this tax are, not using the term "presumed," but "deemed";

e) Thus, it is imperative to conclude that the legislator established expressly and intentionally upon whom the tax falls subjectively;

f) To consider that the legislator established a presumption would be unequivocally an interpretation against the law;

g) It is not a presumption, but a legislative policy option;

h) Equally, it is necessary to consider that article 6, no. 1, of the SVCT Code determines that the taxable event of the tax is ownership as attested by registration or record in national territory;

i) From the articulation between the subjective incidence and the taxable event, it results that only legal situations subject to registration generate the birth of the tax obligation;

j) There is a direct relationship between the moment from which the tax obligation arises and the issuance of the certificate of registration;

k) Having regard to the current configuration of the legal system, it should not be necessary to conduct assessment based on elements that do not appear in public records and documents;

l) The rationale of the regime points to the fact that it was the legislator's intention to create a Single Vehicle Circulation Tax based on taxation of the vehicle owner as recorded in the vehicle registry;

m) Indeed, the SVCT Code implemented a reform of the regime for taxation of vehicles in Portugal, making the vehicle owner as recorded in the property registry the passive subject of the tax, regardless of the circulation of vehicles on public roads;

n) Such rationale results from parliamentary debates surrounding the approval of Decree-Law no. 20/2008, of 31 January;

o) This conclusion is not affected by the existence of environmental concerns, manifested in the taxation of the vehicle user;

p) The interpretation of article 3 of the SVCT Code that the Claimant seeks to assert is offensive to the fundamental principle of trust and legal certainty that should inform any legal relationship;

q) Equally, such interpretation by the Claimant is also offensive to the principle of efficiency of the tax system insofar as it results in an obstruction and increase in the costs of the competencies assigned to the Respondent;

r) Finally, the Claimant's interpretation violates the principle of proportionality insofar as it completely disregards it in confrontation with the principle of taxpayer capacity, when in reality the Claimant has the necessary and appropriate legal mechanisms to safeguard that capacity, without, however, having exercised them in due time;

s) The Claimant does not provide proof of what it alleges, as invoices alone do not constitute suitable documents to prove the sale of vehicles;

t) Even if the Arbitral Tribunal decides on the illegality of the assessments at issue, the arbitration costs should be borne by the Claimant in accordance with the provisions of article 527, no. 1, of the New Code of Civil Procedure;

u) The Claimant does not substantiate the alleged lack of reasoning, merely alleging it.

B) PRELIMINARY ISSUES

The Tribunal is competent and is properly constituted, in accordance with articles 2, no. 1, paragraph a), 5 and 6, all of the LFATM. The parties have legal personality and capacity, are legitimate, and are represented, in accordance with articles 4 and 10 of the LFATM and article 1 of Ordinance no. 112-A/2011, of 22 March.

First and foremost, it is necessary to rule on the exception of lack of material competence invoked by the Respondent with respect to the review of the legality of penalties applied in administrative infraction proceedings.

The competence of the arbitral tribunal is delimited, among other things, by the ordinance binding the tax administration to the jurisdiction of the Administrative Arbitration Center, set out in Ordinance no. 112-A/2011, of 22 March. Upon examination of article 2 of the aforementioned Ordinance, which exhaustively regulates and delimits the claims that may be submitted for review by the material jurisdiction, it is verified that such list does not include claims related to the review of the legality of penalties applied in administrative infraction proceedings. Accordingly, the exception of lack of material competence invoked by the Respondent must be upheld, with the consequent dismissal of the claim in this respect.

No nullities or other preliminary issues affecting the entire proceeding are present, and accordingly it is necessary to now rule on the merits of the claim with respect to the review of the legality of the SVCT assessment acts and Compensatory Interest.

C) SUBJECT MATTER OF THE ARBITRAL DETERMINATION

The following questions are presented to the Tribunal, in the manner described above:

a) Does article 3, no. 1, of the SVCT Code, in providing that the passive subjects of this tax are the owners of the vehicles, deemed to be the natural or legal persons, of public or private law, in whose names the same are registered, establish a presumption or a legislative policy option?

b) Is an invoice a suitable document to prove the alienation of a vehicle?

c) Does non-compliance with the notification obligation referred to in article 118 of the Highway Code prevent the rebuttal of the presumption?

d) Should the vehicles be classified in category "D" of SVCT?

e) Are the assessment acts adequately reasoned?

f) Are the prerequisites for condemning the Respondent to pay indemnificatory interest satisfied?

b) The Claimant alienated the vehicle with registration ..-..-.;

c) No other facts capable of affecting the substantive decision, in light of the possible legal solutions, were proven, and accordingly should be recorded as unproven.

E) LAW

In view of the foregoing, it is first necessary to ascertain the nature of article 3, no. 1, of the SVCT Code. Indeed, the source of the discord between the Claimant and the Respondent centers on the fact that the Claimant considers that the aforementioned legal provision establishes a (rebuttable) presumption and the Respondent considers that a legislative policy option is at issue. Consequently, the Respondent considers that from the combination of articles 3 and 6 of the SVCT Code, it results that the tax falls on the person, natural or legal, who appears as the owner in the respective registry. The Claimant, for its part, extracts from the aforementioned legal provisions the conclusion that the tax must be borne by the real and effective owner regardless of who appears as such in the registry, and that the second part of no. 1 of article 3 of the SVCT Code establishes a presumption. It is therefore necessary to assess this.

The notion of presumption is enshrined in article 349 of the Civil Code, which defines it as "inferences that the law or the judge draws from a known fact to form an unknown fact." Now, the use of presumptions is not unknown in the field of tax law, insofar as they may confer greater practicability to the system and, likewise, be instruments to combat fraud and evasion. Indeed, "faced with doubt about certain facts or situations to be regulated, the rule of law presumes that those contours are those of another fact or situations provided for in another legal rule" (Sousa, Marcelo Rebelo de; Galvão, Sofia, Introduction to the Study of Law, Lex, 2000, Lisbon, p. 241).

On the other hand, it is also important to bear in mind that presumptions may be either explicit or implicit. The former are "revealed by the use of the expression 'presumed' or similar (...)" (Sousa, Jorge Lopes de, Tax Procedure and Process Code, Vol. I, 6th Edition, Áreas Editoras, 2011, Lisbon, p. 589).

By contrast with that category of presumptions, there are implicit presumptions, that is, those that do not result directly and expressly from the terminology used by the legislator. Now, as well noted in the learned arbitral decision rendered in Case no. 14/2013-T: "Examining the Portuguese legal system, we find innumerable norms that establish presumptions using the verb 'deem,' many of which used in the gerund ('deeming' or even 'being deemed'). Examples thereof are the norms enumerated below: In the Civil Code, among others, articles 314, 369 no. 2, 374 no. 1, 376 no. 2, 1629. In the Code of Industrial Property, we cite by way of example article 98 where the term 'deeming' is also used in a presumptive context. Also in the tax legal system one can find the verb 'deem,' namely the term 'is deemed' with a presumptive sense. As explained by Diogo Leite Campos, Benjamim Silva Rodrigues, and Jorge Lopes de Sousa, in annotation no. 3 to article 73 of the General Tax Law, 'presumptions in the matter of tax incidence may be explicit, revealed by the use of the expression presumed or similar (...). However, presumptions may also be implicit in incidence norms, particularly of objective incidence, when certain values of movable or immovable property are considered as constituting taxable material, in situations in which it is not unfeasible to ascertain the actual value' (emphasis ours), then giving several examples of norms in which the verb 'deem' is used, as in no. 2 of article 21 of the IITC happens, by establishing that 'for purposes of determining taxable profit, the market value of increments of patrimonial assets obtained for no consideration is deemed as the acquisition value, and cannot be less than that resulting from the application of the rules for determining the taxable value provided for in the Corporate Income Tax Code' (emphasis ours). (...) Taking into account that the legal system should form a coherent whole, the above examples, accompanied by the doctrine and jurisprudence indicated, by appeal to the systematic element (context of the law and parallel provisions), authorize the conclusion that it is not only when the verb 'presume' is used that we are dealing with a presumption, but also the use of other terms or expressions may serve as the basis for presumptions, particularly the term 'is deemed,' thereby demonstrating that the condition established in no. 2 of article 9 of the CC is satisfied, which requires that legislative intent have in the letter of the law a minimum of verbal correspondence, even if imperfectly expressed." (in www.caad.pt).

In light of the foregoing, it seems appropriate to conclude that article 3, no. 1, of the SVCT Code, in deeming as owners the persons, natural or legal, in whose names the vehicles are registered, does nothing more than establish a presumption. Indeed, admitting that the actual situation to be regulated is unknown (the holder of the ownership right), one resorts to another situation already known to the law (the registration). It is important to note that, as constantly stated in jurisprudence, registration is not constitutive of the right but merely declaratory.

This is therefore a true presumption and not a fiction (which could justify a legislative policy option) insofar as in the latter case the law treats as identical facts that are known to be different. In the concrete case, and as results from the first part of no. 1 of article 3 of the SVCT Code, the intention is to tax the real owner (unknown fact) and, in the second part of the provision, a relationship is established with another fact in law, registration (known fact).

And it is understandable that the Legislator followed this path because, as the Tax Authority rightly points out in its Response, for reasons related to the practicability and management of the tax, and even the prevention of evasion and fraud, the tax should be assessed based on data known to the active subject of the tax relationship. However, these reasons of practicability cannot override other principles of much higher value for the law, particularly Constitutional ones, such as that of equality. Indeed, the Constitutional Court has come to consider that the use of presumptions in tax law is not constitutionally prohibited, provided that such presumptions may be rebutted (cf. Decision of the Constitutional Court no. 348/97, published in the Diário da República, II Series, of 25 July 1997 and Decision no. 211/2003, of 28 April 2003). That is, the Constitutional Court considers in its jurisprudence that, although it is legitimate for the tax legislator to resort to presumptions, it is constitutionally limited by the principles of equality, taxpayer capacity, and fair distribution of income and wealth (which is the fundamental objective of the tax system, as inferred from article 103, no. 1, of the Constitution of the Portuguese Republic), and is prohibited from using absolute presumptions. Indeed, "the establishment of presumptions with the aim of conferring certainty and simplicity to fiscal relationships, of allowing prompt regular collection of taxes and preventing evasion and fraud (...) must be compatible with the principle in question (of tax equality), which occurs through both the constitutional illegitimacy of absolute presumptions insofar as they prevent the taxpayer from proving the non-existence of the taxpayer capacity aimed at in the respective Law, and the requirement of suitability of relative presumptions to present the economic assumption taken into account" (...) "Presumptions must be based on specifically positive elements that rationally justify them and admit contrary proof, so that the tax is linked to a certain, proven economic assumption and not merely a probable one"" (Decision of the Constitutional Court no. 348/1997, citing Casalta Nabais, Tax Contracts (Reflections on their admissibility), p. 279). Thus, and as sustained by the latter Author in the cited Work, p. 265 et seq., "Taxation in accordance with the principle of taxpayer capacity will imply the existence and maintenance of an effective connection between the tax obligation and the economic assumption selected as the subject matter of the tax (...)"

In harmony with the learned jurisprudence of the Constitutional Court and, likewise, the most reputable doctrine, article 73 of the General Tax Law expressly provides that "presumptions established in tax incidence norms always admit contrary proof"

In summary: article 3, no. 1, of the SVCT Code establishes a presumption with respect to the subjective incidence of the tax, which is rebuttable. This is the only interpretation that, moreover, allows for the safeguarding of the constitutional principles indicated by the Tax Authority in its Response which, contrary to what it sustains, would be prejudiced and violated by the acceptance of the Respondent's understanding in its procedural pleadings.

In light of the conclusion reached, it is necessary to analyze a second question that the Tax Authority raises in its Response. Indeed, since this is a presumption (as is now established), the beneficiary thereof (the Respondent) is relieved of the burden of proving the fact to which it leads, and it is incumbent upon the Claimant to prove the contrary. This is the regime that results from article 350 of the Civil Code.

On this point, the Tax Authority sustains that invoices, standing alone, are not suitable documents for the proof required. We do not, however, believe it is correct.

The invoice is, in generic terms, the accounting document through which the merchant specifies the quantity, quality, and prices of goods sold and/or services rendered. It is therefore a title representative of goods sold and/or services rendered.

Because we are in the field of tax law, the provision of article 75, no. 1, of the General Tax Law cannot be disregarded. This legal provision confers a presumption of truthfulness to the accounting elements of taxpayers – in which the invoices in question are included – and accordingly it was incumbent upon the Tax Authority to rebut that presumption through demonstrating the non-existence of correspondence between what is declared in such elements and reality – which it failed to do, merely referring in the abstract that it does not consider that the Claimant had furnished proof.

It is therefore necessary to conclude that the proof attached to the case file is suitable and sufficient to demonstrate the facts invoked by the Claimant (with the exception of the fact for which no proof was provided, of course).

Finally, it is necessary to determine whether the alleged non-compliance with the notification obligation provided for in article 118 of the Highway Code prevents the Claimant from rebutting the presumption. Now, the possibility of rebutting a presumption is not legally conditioned by the fulfillment of the notification obligation referred to in article 118 of the Highway Code. There is no doubt that the fundamental principle of our tax legal system is that of taxation in accordance with material justice. This results, without question, from the provisions of articles 103 and 104 of the Constitution of the Portuguese Republic. Likewise, article 266 of the Constitution of the Portuguese Republic, by providing that administrative activity must, above all, pursue the public interest and the justice and proportionality of measures, demonstrates that the ultimate goal is material truth. Let us then see how the tax system is structured, particularly with respect to declarative obligations. Upon examination of the various tax codes, it is found that the rule is that even declarations through which the Tax Authority determines the taxable material of a tax may be presented outside the respective legal deadline or be substituted. And the consequence, even in those cases in which the taxpayer does not declare its taxable material, or, in the letter of the General Tax Law when there are errors or omissions in declarations that must be presented so that the tax administration specifically determining, assesses or proves the taxable material is that of the eventual application of a penalty in an administrative infraction proceeding. That is, in view of the principle of material truth and the pursuit of public interest, the law penalizes the taxpayer for the omission, but does not thereby obscure the material truth of the concrete case. It is therefore evident that the tax legal system, in its entirety, is designed so that non-timely compliance with a declarative obligation does not have drastic, definitive, and possibly disproportionate consequences. Accordingly, it seems appropriate to conclude that the sole consequence flowing from non-compliance with the provisions of article 118 of the Highway Code would correspond, if the respective prerequisites are met, to the application of a penalty in an administrative infraction proceeding.

In summary: from the facts established as proven, it results that each of the assessment acts in question (with the exception of assessment acts nos. …, …, …, undertaken with reference to the vehicle with registration ..-..-..), pertains to a fiscal year in which the Claimant, on the date on which the taxable event occurs, was no longer the owner of each of the vehicles in question. Accordingly, given that, as we have already seen, the SVCT intends to fall subjectively on the real owner of the vehicle in each year and in the month of registration (cf. articles 3, 4, and 6 of the SVCT Code), it is necessary to conclude that the assessment acts in question (with the exception of assessment acts nos. …, …, …, undertaken with reference to the vehicle with registration ..-..-..), violate the provisions of the aforementioned legal provisions and should be declared illegal and annulled, as they were undertaken in violation of the norms and legal principles in effect (cf. article 135 of the Administrative Procedure Code).

Finally, in light of the conclusion reached above, it is also necessary, with reference to the vehicle with registration ..-..-.., to which assessment acts nos. …, …, … correspond, to analyze the argument invoked and which concerns the legal error in the classification of the aforementioned vehicle. The Claimant invokes that, in light of the provisions of article 2, no. 1, paragraph d), of the SVCT Code, it should be classified in category "D" and not in category "C" of this tax. In accordance with the aforementioned legal provision, category "D" includes: "Freight vehicles and mixed-use vehicles with gross weight exceeding 2,500 kg, affected by public goods transport, transport for account of others, or rental without driver having those purposes." Now, given the factual matters established, there is no doubt that the vehicle in question is licensed for the activity of goods transport for account of others. Likewise, it results from the administrative infraction report attached to the case file that the vehicle in question should be qualified as heavy. It results from the provisions of article 106, no. 1, paragraph b), of the Highway Code that heavy vehicles are those whose gross weight exceeds 3,500 kg or with seating capacity exceeding 9 places, including the driver. That is, vehicles should be qualified as heavy that, regardless of gross weight, have seating capacity exceeding nine places. In light of the foregoing, and in the absence of further proof, which, given the provisions of article 74 of the General Tax Law, it was incumbent upon the Claimant to furnish, the prerequisites upon which the law makes dependent the qualification of a certain vehicle as category "D" for purposes of the SVCT Code are not demonstrated. This argument of the Claimant therefore does not succeed.

Finally, it is necessary to analyze whether assessment acts nos. …, …, … are adequately reasoned. As article 77, no. 1, of the General Tax Law requires, "the procedural decision is always reasoned by means of a succinct exposition of the factual and legal reasons that motivated it, and the reasoning may consist of mere declaration of agreement with the grounds of previous opinions, information, or proposals, including those that are part of the tax audit report." That is, the Tax Authority has the legal duty to externalize the course of its cognition so that the addressee can understand the reason for the tax assessment. The duty of motivation or reasoning of any administrative or tax act has two associated purposes: (i) on one hand, to inform the respective addressee of the reasons or motives that led to the decision being made in a certain direction; and (ii) on the other hand, to allow review of the legality of the decision and the validity of the reasons underlying a concrete decision. As Vieira de Andrade teaches, "the imperative of express reasoning (...) thus typically plays a role of functional guarantee, with the intention of ensuring the rationality and reviewability of the characteristic moments of the administrative function, of those in which the organs of the Administration take decisions of authority that produce legal modifications in the external world" (cf. ANDRADE, José Carlos Vieira - The Duty of Express Reasoning of Administrative Acts, Coimbra, 1992, p. 215). Now, in the case at issue, the assessment acts in question contain all the factual and legal elements that allow – as they indeed did allow – the Claimant to analyze and evaluate the reasons underlying them. Accordingly, no other conclusion can be reached than that the acts in question are adequately reasoned, and this argument of the Claimant does not succeed.

With reference to the SVCT assessment acts whose illegality is hereby declared, it is necessary to conclude for the illegality of the respective compensatory interest, insofar as, with the non-existence of unpaid tax, the prerequisites to which article 35 of the General Tax Law refers cannot, naturally, be met, particularly because there is no delay in the tax assessment.

Finally, the Claimant requests reimbursement of the amounts paid, plus indemnificatory interest, in accordance with the provisions of article 43 of the General Tax Law. Let us then examine:

Article 43 of the General Tax Law provides that the taxpayer shall be entitled to be compensated through indemnificatory interest whenever unjustified payment of tax is attributable to error on the part of the services. Now, in the case at issue, the Claimant did not, as results from the judgment of the factual matter, furnish proof that it paid the tax that was assessed against it. Accordingly, the prerequisites upon which the law makes dependent the conviction of the Respondent to pay indemnificatory interest are not met.

DECISION

In light of the foregoing, this Arbitral Tribunal decides to rule partially in favor of the claim and consequently:

a) Rule in favor of the exception of lack of material competence of this Tribunal to review the legality of penalties applied in administrative infraction proceedings, dismissing the Respondent;

b) Declare the illegality of the SVCT and Compensatory Interest assessment acts nos. …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, …, and annul them;

c) Dismiss the Respondent from the claim with respect to assessment acts nos. …, … and …, undertaken with reference to the years 2009, 2010, and 2011 and to the vehicle with registration ..-..-.., in the value of € 1,185.63;

d) Dismiss the Respondent from the claim for the conviction to pay indemnificatory interest;

e) Condemn the Claimant and the Respondent to payment of costs in proportion to their failure, fixed at 25% for the Claimant and 75% for the Respondent.

The value of the action is fixed at € 19,155.14 (nineteen thousand, one hundred and fifty-five euros and fourteen cents), in accordance with the provisions of article 97-A, no. 1, paragraph a), of the TPPC, applicable by virtue of article 29, no. 1, paragraph a), of the LFATM.

The value of the Arbitration Fee is fixed at € 1,224.00, in accordance with Table I of the Regulation of Costs of Tax Arbitration Proceedings, to be paid by the Claimant and the Respondent as stated above, in accordance with articles 12, no. 2, 22, no. 4, of the LFATM and 4 of the aforementioned Regulation.

Let notification be made.

Under Portuguese IUC law, liability for tax payment is determined by registered ownership as shown in the vehicle registry, not actual ownership. Article 3 of the IUC Code designates the registered owner as the taxable person, while Article 6 establishes that the taxable event is ownership 'as attested by registration.' The Tax Authority argues this creates a legislative policy choice rather than a rebuttable presumption. When a vehicle is sold or written off, the former owner remains liable unless the ownership change is properly registered and notified to IMTT (Institute for Mobility and Land Transport) pursuant to Highway Code Article 118(4). This system prioritizes legal certainty and administrative efficiency over investigating actual ownership circumstances.
Does the CAAD Tax Arbitral Tribunal have jurisdiction to rule on IUC subjective incidence disputes?
Yes, the CAAD Tax Arbitral Tribunal has material jurisdiction to rule on disputes concerning IUC subjective incidence (who owes the tax). Article 2(1)(a) of Decree-Law 10/2011 grants CAAD competence over the legality of tax assessment acts, including IUC assessments disputed under Articles 99 and 102(1)(d) of the Tax Procedure and Process Code. However, the Tax Authority raised a preliminary objection arguing the tribunal lacks competence to review the legality of penalties imposed in administrative infraction proceedings, which falls outside the scope of tax assessment challenges. The tribunal must rule on this jurisdictional exception before addressing the merits of the IUC liability dispute.
Can a former vehicle owner challenge IUC assessments issued after transferring ownership?
A former vehicle owner can challenge IUC assessments issued after transferring ownership, but faces significant legal and evidentiary obstacles. The claimant must overcome the legal framework that ties IUC liability to registered ownership rather than actual ownership. To succeed, the challenger must prove: (1) actual transfer of ownership occurred before the relevant tax year; (2) compliance with legal notification requirements under Highway Code Article 118(4); and (3) that the IUC Code provisions create a rebuttable presumption rather than an absolute rule. The Tax Authority contends that sales invoices alone are insufficient proof and that the system intentionally bases taxation on registration records. Former owners who failed to properly register ownership transfers face an uphill battle, as the law prioritizes administrative certainty over investigating factual ownership circumstances.
What legal provisions govern subjective incidence under Portugal's Imposto Único de Circulação (IUC)?
The legal provisions governing subjective incidence under Portugal's IUC are primarily Articles 3 and 6 of the IUC Code (established by Decree-Law 20/2008 of 31 January). Article 3(1) designates as taxable persons those 'deemed' to be vehicle owners for tax purposes. Article 6(1) defines the taxable event as 'ownership as attested by registration or record in national territory.' These provisions are interpreted in conjunction with Highway Code Article 118(4), which imposes notification obligations when vehicles are sold. The Tax Authority argues these provisions reflect a deliberate legislative choice to base taxation on vehicle registry records rather than actual ownership, serving principles of legal certainty, administrative efficiency, and proportionality. The Claimant counters that these provisions establish only a rebuttable presumption that can be overcome by proving actual ownership transfer before the tax year.
How does vehicle registration status affect IUC tax liability after sale or total loss of the vehicle?
Vehicle registration status is determinative of IUC tax liability after sale or total loss under the Tax Authority's interpretation. Article 6(1) of the IUC Code states the taxable event is ownership 'as attested by registration,' creating a direct link between registration and tax obligation. The Authority argues only legal situations subject to registration generate tax liability, meaning unregistered transfers do not affect IUC obligations. When a vehicle is sold or totally lost, the former registered owner remains liable until the ownership change is properly registered and the seller complies with Highway Code Article 118(4) notification requirements. This registration-based system prioritizes administrative efficiency and legal certainty over investigating actual economic circumstances. Sellers who fail to ensure proper registration transfer remain exposed to IUC assessments for subsequent tax years, even if they no longer possess or control the vehicle.
