Process: 160/2015-T

Date: November 16, 2015

Tax Type: IUC

Source: Original CAAD Decision

Summary

This CAAD tax arbitration case (160/2015-T) addresses the subjective incidence of Portugal's Single Circulation Tax (IUC) when vehicle ownership changes before registration cancellation. The Claimant company sold and exported three vehicles to Angola in January-March 2009, with customs certificates confirming the exports. However, the Institute for Mobility and Transport (IMT) only cancelled the vehicle registrations in April-June 2009, after the annual IUC anniversary dates had passed. The Tax Authority issued IUC assessments for 2009 plus compensatory interest, totaling €1,527.93. The Claimant challenged these assessments arguing it was no longer the owner on the anniversary dates under Article 6(3) and Article 2(2) of the IUC Code. The Tax Authority raised a preliminary objection of lack of passive standing, contending the registration delay was attributable to IMT or the taxpayer, not the tax administration. The Authority further argued the Claimant failed to request IMT correct the cancellation dates as required by Article 3(1) of the IUC Code. The core legal issue concerns whether the legal presumption in Article 6(3) of the IUC Code—which deems the registered owner as the taxable person—can be rebutted when actual ownership transfer occurred before the tax anniversary date but administrative cancellation occurred afterward. This case exemplifies common disputes over IUC liability timing, the distinction between civil ownership transfer and administrative registration changes, and the burden of proof required to overcome statutory presumptions in Portuguese vehicle taxation.

ARBITRAL DECISION

CAAD: Tax Arbitration

Case no. 160/2015-T

Claimant: a…, Lda

Respondent: Tax and Customs Authority

Subject Matter: Single Circulation Tax

I. REPORT

  1. On 10 March 2015, the company a…, Lda, taxpayer no. …, hereinafter identified as the Claimant, submitted a request for arbitral pronouncement, pursuant to articles 2, no. 1, paragraph a) and 10 of Decree-Law no. 10/2011 of 20 January (Legal Framework for Tax Arbitration, hereinafter referred to as RJAT), in conjunction with article 102 of the Tax Procedure and Process Code (CPPT), 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 pronouncement, the Claimant seeks that the Arbitral Tribunal declare:

a) the illegality of the assessment act for Single Circulation Tax no. 2009 …, of 14 October 2013, concerning the month of February 2009, and the vehicle with registration …-…-…, in the amount of € 454.00, and of Compensatory Interest no. …, in the amount of € 83.93, for a total of € 537.93.

b) the illegality of the assessment act for Single Circulation Tax no. 2009 …, of 14 October 2013, concerning the month of May 2009, and the vehicle with registration …-…-…, in the amount of € 386.00, and of Compensatory Interest no. … in the amount of € 67.51, for a total of € 453.51.

c) the illegality of the assessment act for Single Circulation Tax no. 2009 …, of 14 October 2013, concerning the month of March 2009, and the vehicle with registration …-…-…, in the amount of € 454.00, and of Compensatory Interest no. …, in the amount of € 82.49, for a total of € 536.49.

  1. The request for constitution of the arbitral tribunal was accepted on 11 March 2015 by His Excellency the President of CAAD and, subsequently, notification was served upon the Tax and Customs Authority (hereinafter identified as the Respondent Entity).

  2. The Claimant did not proceed with the appointment of an arbitrator and therefore, pursuant to article 6, no. 1 of the RJAT, the undersigned was appointed by the President of the CAAD Ethics Council to constitute the present singular Arbitral Tribunal, with the appointment being accepted in the terms legally provided for.

  3. On 19 October 2015, the meeting of the arbitral tribunal provided for in article 18 of the RJAT took place.

  4. The Claimant sustains its request, in summary, on the understanding that in the year 2009, more precisely on the anniversary date of the respective registrations, it was no longer the owner of the vehicles in question and, consequently, could not be considered the passive subject of the tax, pursuant to article 6, no. 3, read in conjunction with article 2, no. 2 of the Single Circulation Tax Code, and therefore the contested assessments are illegal and should be annulled accordingly.

  5. The Respondent Entity sustains its lack of passive standing to appear in court on the grounds that, in its view, the Claimant has deduced a request for condemnation of the Tax Administration for annulment of the Single Circulation Tax assessment notes for the years 2009, basing said request on the fact that it had requested the cancellation of the registrations of the vehicles in question from the Institute for Mobility and Transport (IMT), based on certificates issued by Lisbon Customs, which certify the export of the same to Angola, but the registrations were cancelled by IMT not on the dates of export, but on dates subsequently reported.

  6. For the Respondent Entity, such procedural omission is not attributable to it, as it is external to it, and therefore, if confirmed, will be attributable to the owner or to the IMT, and therefore in light of the legal relationship thus configured its lack of standing to appear in court is manifest.

  7. Notwithstanding, the Respondent Entity sustains the maintenance of the contested acts to the extent that the Claimant did not provide proof of having taken steps with IMT to contradict the provision in article 3, no. 1 of the Single Circulation Tax Code, namely with regard to the possible correction of the dates of cancellation of the registrations.

  8. And, finally, it requests the condemnation of the Claimant to bear the arbitral costs for not having proceeded with the updating of the vehicle registration.

II. PRELIMINARY RULING

The Tribunal is materially competent and is regularly constituted, pursuant to articles 2, no. 1, paragraph a), 5 and 6, all of the RJAT.

The parties have legal personality and capacity and are duly represented, pursuant to articles 4 and 10 of the RJAT and article 1 of Regulation no. 112-A/2011 of 22 March.

There are no nullities and therefore the merits of the request must be examined.

Unproven Facts

No essential facts with relevance to the assessment of the merits of the case were found to remain unproven.

V. ON THE LAW

  1. The first question under examination in the present proceedings concerns the alleged lack of passive standing of the Tax and Customs Authority, represented by its highest-ranking official, to appear in court.

The relevant interest is the criterion for assessing the concept of standing.

Pursuant to article 30 of the Code of Civil Procedure, the plaintiff is a legitimate party when it has a direct interest in bringing the action, revealed by the utility derived from the action succeeding, and the defendant is a legitimate party when it has a direct interest in defending, revealed by the prejudice that would result from the action succeeding. As a rule, the subjects of the relationship in dispute, as configured by the plaintiff, are considered to be holders of the relevant interest.

The Respondent Entity sustains its lack of standing on the grounds that the Claimant has deduced "a request for condemnation of the Tax Administration to annul the Single Circulation Tax assessment notes for the years 2009, basing said request on the fact that it had requested from IMT the cancellation of the registrations of the vehicles now in question, based on certificates issued by Lisbon Maritime Customs, and which certify the export of the same to Angola. But the registrations were cancelled by IMT not on the dates of export, but reported to the dates of 07/04/2009 and 24/06/2009." (cf. articles 10 and 11 of the Respondent Entity's response).

However, contrary to what is alleged by the Respondent Entity, the Claimant does not base its request for annulment of the contested assessment acts on the dates to which IMT reported the cancellation of the registrations but on the fact that on the date of verification of the respective tax events it was not the passive subject of the tax, as it was not the owner of the respective vehicles (cf. articles 14 and 15 of the request for arbitral pronouncement).

Since the present proceedings concern the annulment of assessment acts issued by the Director-General of the Tax and Customs Authority, it is manifest that the Respondent Entity has an interest in defending and, consequently, its standing (numbers 1 and 3 of article 9 of the Tax Procedure and Process Code and Judgment of the Supreme Administrative Court delivered in Case no. 015123, on 23-07-1981, in www.dgsi.pt) and, likewise, the competence of this tribunal to examine the legality of those same acts (cf. articles 2 and 4 of the RJAT).

The alleged interest of IMT in intervening in the present proceedings is not discernible since, contrary to what is sustained by the Respondent Entity, IMT does not have a personal and direct interest in the outcome of the dispute, as no prejudice would result to it from the annulment of the contested assessment acts.

In light of the foregoing, the exception of lack of standing invoked by the Respondent Entity is found to be without merit.

  1. The second question under examination in the present proceedings concerns determining whether the rule of article 3, no. 1 of the Single Circulation Tax Code permits the person in whose name the vehicle is registered at the Registry to demonstrate, through the means of proof admitted in law, that notwithstanding this fact, the person is not the owner of the vehicle in the period to which the tax relates and thus to preclude the tax obligation that rests upon that person.

Article 3, no. 1 of the Single Circulation Tax Code provides that "the passive subjects of the tax are the owners of the vehicles, considered as such the natural or legal persons, of public or private law, in whose names the same are registered." According to this legal provision, the passive subjects of the tax are, therefore, the owners of the vehicles.

Indeed, pursuant to the Single Circulation Tax Code, the tax is due by the owner of the vehicle until the cancellation of the registration or registration as a result of scrapping effected in accordance with the law (cf. article 4, no. 3 of the Single Circulation Tax Code), with the ownership of vehicles being taxed, independently of their respective use or enjoyment.

For the purposes of concretizing subjective incidence, those considered to be owners are natural or legal persons in whose names the vehicles are registered.

In this context, the Tax Administration assesses the tax in accordance with the elements constituting the Single Circulation Tax database, the updating of which is effected based on the elements supplied by the Institute of Registries and Notaries (IRN) and by the Institute for Mobility and Transport (IMT).

Article 3, no. 1 of the Single Circulation Tax Code thus establishes a legal presumption in accordance with which the person inscribed in the registry as owner of the vehicle is considered to be the passive subject of the tax.

The use of the expression "considered as," rather than the expression "presumed," does not negate this conclusion.

As better developed in the Arbitral Decision delivered in Case no. 14/2013-T "Examining the Portuguese legal system, we find innumerable norms that establish presumptions using the verb to consider, many of which employed in the gerund form ("considering" or even "considered as"). 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 Industrial Property Code, we refer by way of example to article 98 where also the term "considered" is used in a presumptive context. Also in the tax legal system one can find the verb "to consider," namely the term "is considered" 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 matters of tax incidence can be explicit, revealed by the use of the expression is presumed or similar (…). However, presumptions can also be implicit in rules of incidence, namely of objective incidence, when certain values of movable or immovable property are considered as constituting taxable matter, in situations in which it is not unfeasible to ascertain the actual value" (emphasis ours), giving thereafter some examples of norms in which the verb "to consider" is used, as in no. 2 of article 21 of the Corporate Income Tax Code happens, when establishing that "for the purposes of determining taxable profit, the value of acquisition of patrimonial increases obtained gratuitously is considered to be its market value, not being able to be less than what results from the application of the rules for determining the taxable value provided for in the Stamp Duty Code." (emphasis ours). (…) Taking into account that the legal system must form a coherent whole, the above examples, accompanied by the doctrine and case law indicated, by appeal to the systematic element (context of the law and parallel places), authorize the conclusion that it is not only when the verb "to presume" is used that we are faced with a presumption, but also the use of other terms or expressions can serve as the basis for presumptions, namely the term "is considered," thus showing that the condition established in no. 2 of article 9 of the Civil Code is met, which requires that legislative thought have in the letter of the law a minimum of verbal correspondence, although imperfectly expressed." (in www.caad.pt).

As also pointed out in the cited Arbitral Decision, the ratio legis of the Single Circulation Tax points in the direction of taxing the actual owners or users of vehicles, as these are the ones that have the polluting potential causing environmental costs to the community (cf. article 3, nos. 1 and 2 of the Single Circulation Tax Code).

Indeed, the Single Circulation Tax seeks to burden taxpayers in measure of the environmental and road costs that they cause, in concretization of a general rule of tax equality, as expressed in its article 1.

It is not apparent that the taxation of former owners could contribute to this objective, which will only be fulfilled if the taxation targets the actual owner or user.

Furthermore, registration has no constitutive effect in our legal system, having rather merely a declarative function (cf. Judgment of the Supreme Court of Justice delivered in Case no. 00A217, of 20-06-2000 and Judgment of the Supreme Court of Justice delivered in Case no. 087725, of 13-02-1996, in www.dgsi.pt).

The "definitive registration constitutes a presumption that the right exists and belongs to the registered holder, in the precise terms in which the registration defines it. But, as the petitioner rightly states, this registration presumption is rebuttable – although not by counter-proof, but rather through proof to the contrary – for registration, even if definitive, constitutes mere rebuttable presumption." (cf. Judgment of the Supreme Court of Justice in Case no. 07B4528, of 29-01-2008, in www.dgsi.pt), which means that also the nature of registration in our legal system does not preclude the conclusion reached that we are faced in the present case with a presumption.

Now, as article 3, no. 1 of the Single Circulation Tax Code establishes a presumption, this presumption is a rebuttable presumption that conflicts with a rule of incidence (subjective) of the tax.

The presumptions established in rules of tax incidence always admit proof to the contrary, since the provision in article 73 of the General Tax Law expressly precludes, in the domain of rules of tax incidence, the possibility of existence of irrebuttable presumptions.

The "prohibition of irrebuttable presumptions that emanates from art. 73 of the General Tax Law is limited to rules of tax incidence, but covering both those of subjective incidence and those of objective or real incidence. Rules of incidence, in a broad sense, are those that "define the plane of incidence or rather, the complex of presuppositions from whose conjunction results the birth of the tax obligation, as well as the elements of the same obligation. In this sense, rules of incidence are those that determine the active and passive subjects of the tax obligation, those that indicate what the taxable matter is, the rate and the tax benefits" (cf. SOUSA, Jorge Lopes de - Tax Procedure and Process Code – Annotated and Commented, Áreas Editora, 6th edition, 2011, vol. I, page 586).

Thus, as article 3, no. 1 of the Single Circulation Tax Code establishes a rebuttable presumption, the entity inscribed in the registry as owner of the vehicle and which, for that reason, was considered by the Tax Administration as the passive subject of the tax, can present evidence elements aimed at demonstrating that the holder of the property is another person, to whom the property was transferred.

And contrary to what is alleged by the Respondent Entity, the possible non-realization of steps with IMT for correction of the dates of cancellation of registrations does not preclude the rebuttable character of the presumption under examination, in accordance with the invocation of article 73 of the General Tax Law.

The Single Circulation Tax is of annual periodicity, being due in full in each year to which it relates, the taxation period corresponding to the year that begins on the date of registration or on each of its anniversaries, regarding vehicles in categories A, B, C, D and E (cf. article 4, nos. 1 and 2 of the Single Circulation Tax Code).

In the case at hand, it was proven that the Claimant sold the vehicles in question on dates prior to the anniversaries of the respective registrations, in the year to which the assessments in question relate, in accordance with the Invoices and Customs Clearance Forms (DAU) attached to the record.

And, as these transfers occurred on dates prior to the anniversaries of the registrations, in the year to which the assessments in question relate, the Claimant was no longer the passive subject of the tax with reference to the assessments in question, the annulment of which, consequently, is determined.

  1. The third question raised concerns responsibility for payment of the arbitral costs, which, in the view of the Respondent Entity, cannot be attributed to it, since vehicle registration is the cornerstone of the entire edifice on which the Single Circulation Tax is based, but responsibility for vehicle registration is not within its sphere and, likewise, because there is no declarative obligation that would permit the Respondent Entity to have knowledge of the transfer of automobiles. It further contends that the Claimant did not proceed with the care that was required of it in updating the vehicle registration.

To support this view, the Respondent Entity invokes the decision in Case no. 26/2013-T in which the right to indemnifying interest was refused since "in promoting the off-office assessment of the Single Circulation Tax considering the claimant as the passive subject of this tax, the Tax Administration limited itself to complying with the rule of article 3, no. 1 of the Single Circulation Tax Code, which, as abundantly referred to above, attributes such quality to persons in whose names the vehicles are registered. On the other hand, also as already concluded, the aforementioned rule has the nature of legal presumption, from which it follows, for the Tax Administration, the right to assess the tax and demand it from those persons, without need to prove the facts that lead to it, as expressly provided in no. 1 of article 350 of the Civil Code.

In the case at hand, the Claimant demonstrated to the Respondent Entity at a time prior to the submission of the request for arbitral pronouncement – both in the context of gracious complaint proceedings, and within the scope of hierarchical appeal – that it was not the owner of the vehicles on the date of verification of the tax events.

In light of the foregoing, it is concluded that the Respondent Entity gave rise to the present proceedings in the terms and for the purposes of number 1 of article 527 of the Code of Civil Procedure, and is consequently condemned to bear the costs.

VI. DECISION

Frequently Asked Questions

Automatically Created

Who is considered the taxable person for IUC (Imposto Único de Circulação) when vehicle ownership changes?
Under Article 6(3) of the IUC Code, the taxable person is whoever appears as the registered owner in the vehicle registration on the anniversary date of that registration. This creates a legal presumption linking tax liability to registration status rather than actual ownership. However, this presumption can be rebutted with sufficient proof that ownership had transferred before the anniversary date, such as through sale invoices, export documentation, or other evidence of transfer. When ownership changes occur but registration cancellation is delayed, disputes arise over whether the former registered owner or the actual new owner bears IUC liability.
Can a former vehicle owner challenge IUC tax assessments based on subjective incidence rules?
Yes, a former vehicle owner can challenge IUC assessments based on subjective incidence rules by demonstrating they were not the actual owner on the tax anniversary date. The challenge must rebut the legal presumption in Article 6(3) of the IUC Code through documentary evidence such as sale contracts, invoices, export certificates, or proof of delivery. The taxpayer must prove the ownership transfer occurred before the relevant anniversary date and, ideally, show they took reasonable steps to request registration cancellation from IMT. CAAD arbitration under Decree-Law 10/2011 provides a forum for such challenges, allowing taxpayers to contest the Tax Authority's determination of who constitutes the proper taxable person.
How do legal presumptions under Article 6(3) of the IUC Code affect tax liability for registered vehicle owners?
Article 6(3) of the IUC Code establishes a legal presumption that the person listed as the registered owner in the vehicle registration is the taxable person for IUC purposes. This presumption operates on the anniversary date of the vehicle's registration, making registration status—rather than actual ownership—the primary determinant of tax liability. However, Portuguese law generally allows legal presumptions to be rebutted with contrary proof. A taxpayer can overcome this presumption by providing compelling evidence of actual ownership transfer prior to the anniversary date, such as sale documentation, export certificates, or payment records. The burden of proof rests on the taxpayer to demonstrate that despite appearing as the registered owner, they had legally transferred ownership before the tax obligation arose.
What is the CAAD arbitration procedure for disputing IUC tax liquidation acts in Portugal?
The CAAD (Centro de Arbitragem Administrativa) arbitration procedure for disputing IUC assessments follows the Legal Framework for Tax Arbitration (RJAT - Decree-Law 10/2011). Taxpayers must submit an arbitration request under Articles 2(1)(a) and 10 of RJAT, in conjunction with Article 102 of the Tax Procedure and Process Code (CPPT). The process involves: (1) filing a written request identifying the contested tax acts and legal grounds; (2) appointment of arbitrator(s); (3) notification to the Tax Authority to file a response; (4) an arbitral tribunal meeting under Article 18 of RJAT; and (5) issuance of a binding arbitral decision. The procedure provides an alternative to judicial courts for resolving tax disputes, typically with faster resolution times and specialized tax expertise.
Are compensatory interest charges valid on IUC assessments issued years after the taxable event?
Compensatory interest charges on IUC assessments issued years after the taxable event are generally valid under Portuguese tax law, provided the assessment falls within the applicable statute of limitations period. Compensatory interest compensates the state for the delayed receipt of tax revenues and accrues from the original payment deadline until actual payment, regardless of whether the delay resulted from taxpayer action or administrative processing time. However, the validity of such interest charges can be challenged if: (1) the underlying tax assessment is illegal or without factual basis; (2) the delay resulted entirely from administrative error with no taxpayer fault; or (3) the assessment period exceeded statutory limitations. In this case, the 2013 assessments for 2009 tax obligations included compensatory interest totaling €233.93, which the Claimant contested alongside the principal IUC amounts.
