Summary

This tax arbitration case (Process 820/2014-T) addresses the subjective incidence of Portugal's Unique Circulation Tax (IUC) when vehicles have been sold or written off before the taxation period. The claimant, a vehicle trading and leasing company, challenged IUC assessments for 2014 totaling €20,146.52 for vehicles no longer in its ownership. The core dispute centers on whether vehicle registry creates an irrebuttable presumption of ownership for IUC purposes. The company argued it sold vehicles to third parties and wrote off others as total losses prior to the 2014 tax period, submitting sales invoices as proof. However, purchasers failed to register ownership transfers, leaving the claimant listed as the registered owner. The claimant contended that Article 3(1) of the IUC Code's phrase 'considered as such' establishes a rebuttable legal presumption (juris tantum), not an absolute one. Supporting this interpretation, the company cited Article 73 of the General Tax Law, which prohibits irrebuttable presumptions in taxation and requires that presumptions concerning tax scope always admit contrary proof. The claimant further argued that vehicle registration is declarative, not constitutive, serving only publicity purposes. Additionally, the IUC's underlying equivalence principle linking tax liability to environmental and road costs from actual circulation supports that non-owners shouldn't bear the tax burden. The Tax Authority's response challenged this interpretation as distorting the law's letter and systematic context, asserting the legislator intentionally established registered owners as liable persons under Article 3(1). The excerpt does not include the arbitral tribunal's final decision or legal reasoning, concluding mid-argument. The case raises fundamental questions about balancing registry publicity functions against substantive ownership rights in tax law, and whether formal registration can override actual economic and legal reality when determining tax liability.

ARBITRAL AWARD

A – REPORT

  1. A…, LDA., legal entity no. …, with registered office in …, Oeiras, has requested the constitution of an arbitral tribunal, in accordance with the provisions of art. 2, no. 1, a) and 10, nos. 1 and 2 of the Legal Regime for Tax Arbitration, provided for in Decree-Law 10/2011, of 20 January, hereinafter referred to as "LRTA", and of articles 1 and 2 of Order no. 112-A/2011, of 22 March, in view of the dismissal of the gracious appeals that it filed, in which the illegality of the assessments for Unique Circulation Tax is disputed, relating to the year 2014, as well as the recognition of the right to compensatory interest, with the Tax and Customs Authority (hereinafter referred to as "TCA") being named as respondent.

  2. The request for constitution of a single arbitral tribunal having been admitted, and the claimant having not opted for the appointment of an arbitrator, in accordance with the provisions of subparagraph a) of no. 2 of article 6 and subparagraph b) of no. 1 of article 11 of the LRTA, as amended by article 228 of Law no. 66-B/2012, of 31 December, the Deontological Council appointed the undersigned as arbitrator.

The parties were notified of this appointment and did not express any wish to refuse the appointment of the arbitrator, in accordance with the combined provisions of article 11, no. 1, subparagraphs a) and b) of the LRTA and articles 6 and 7 of the Deontological Code, and, in accordance with the provision of subparagraph c) of no. 1 of article 11 of the LRTA, as amended by article 228 of Law no. 66-B/2012, of 31 December, the arbitral tribunal was constituted on 25-02-2015.

  1. Notified, the TCA submitted a response in which it raised no exceptions.

  2. The holding of the meeting provided for in art. 18 of the LRTA was dispensed with, as well as the submission of arguments, with the consent of the parties.

  1. The claimant seeks to have declared the illegality and consequent annulment of the assessments for Unique Circulation Tax relating to the year 2014, which were the subject of the gracious appeals that it filed and to which the nos. … were assigned, which were dismissed, with the consequent restitution of the tax paid, plus compensatory interest, alleging in summary:

a) It is a commercial company whose principal activity consists of the purchase, sale and leasing of machines and motor vehicles.

b) In the exercise of its activity, it offers clients various solutions within the scope of long-term vehicle leasing and the sale of motor vehicles.

c) It was notified of the UCT assessment notes that are the subject of this case and paid the corresponding tax.

d) It filed gracious appeals in relation to such assessments.

e) The aforementioned assessments relate to vehicles that were sold to third parties (the claimant's clients) in a moment prior to the taxation period.

f) Also in question is the unique circulation tax, for the same years, relating to vehicles that were written off as total loss and in relation to which the respective registrations were cancelled in a moment prior to the taxation period.

g) To avoid future tax enforcement proceedings and the costs inherent to the provision of guarantees for the suspension of such proceedings, it opted to pay the tax, having paid the total amount of €20,146.52.

h) Although the taxable event is the ownership of the vehicle, the registered presumption is rebuttable.

i) The right of ownership over motor vehicles is subject to mandatory registration and, in accordance with art. 29 of the Motor Vehicle Registry Regulation, the provisions relating to property registration are applicable to the registration of motor vehicles, with the necessary adaptations, to the extent indispensable to fill gaps in the specific regulation thereof (and compatible with the nature of motor vehicles).

j) In accordance with art. 7 of the Property Registry Code, the definitive registration constitutes a presumption that the right exists and belongs to the registered owner, in the exact terms in which the registration defines it.

k) Absolute presumptions (iuris et de iure) are those that do not admit proof to the contrary, that is, cannot be rebutted. Now, a legal presumption can only be considered rebuttable when the law so determines.

l) The registration of motor vehicle ownership is mandatory and serves only to "give publicity" to the legal situation of assets. There is, moreover, no provision in the Portuguese legal system concerning the constitutive character of the registration of motor vehicle ownership.

m) The motor vehicles listed in the aforementioned UCT assessments are effectively registered in the name of the current claimant, following their acquisition; the registration constituted a presumption that it exists and belongs to the registered owner in the exact terms defined in the registration. We are faced with a rebuttable presumption (juris tantum).

n) To rebut this presumption it is necessary either to prove the nullity of the registration or to demonstrate the invalidity of the transaction, or furthermore, that the ownership of the registered right belongs to another.

o) It was precisely this demonstration – that the ownership of the vehicle belongs to a third party – that the claimant made, by attaching sales invoices for the vehicles and their salvage, all dated months prior to the tax obligation demanded.

p) The purchasers of the vehicles had not duly effected their registrations of the vehicles at the Motor Vehicle Registry Office, so the claimant continued to appear as the owner thereof in this database.

q) In accordance with the provisions of art. 73 of the General Tax Law, the presumptions established in the rules concerning the scope of taxation always admit proof to the contrary; irrebuttable presumptions are prohibited.

r) Tax legislation and, in particular, the UCT Code, cannot ignore the role of the motor vehicle registry and contradict the prevailing judicial understanding concerning the nature of the registry. It cannot be ignored that the motor vehicle registry, although mandatory, does not have a constitutive nature, being rather of a declarative or publicity nature.

s) Furthermore, the UCT has underlying the principle of equivalence which has embodied environmental concerns by establishing that the tax should burden taxpayers for the environmental and road costs caused by motor vehicle circulation.

t) Furthermore, the expression "considered as such" contained in no. 1 of art. 3 of the UCT Code constitutes a legal presumption and the same is rebuttable.

u) In accordance with the provisions of art. 64 of the Tax Procedure Code, the presumptions concerning the scope of taxation may be rebutted by way of gracious appeal of the tax acts (in this case the assessment acts) based on them, which the claimant did, with the submission of the gracious appeals aforementioned, where it attached copies of all the sales invoices for the vehicles and their salvage.

v) On the date of the tax obligation's due date, the claimant was no longer the owner of the aforementioned vehicles, as the respective transfers had already taken place.

  1. In turn, the respondent submitted a response alleging, in summary:

a) The position advocated by the claimant not only suffers from a distorted reading of the letter of the law, but also from the adoption of an interpretation that disregards the systematic element, violating the unity of the regime established throughout the UCT Code and, more broadly, throughout the entire legal-tax system and, finally, stems from an interpretation that ignores the ratio of the regime established in the article in question, and likewise throughout the UCT Code.

b) The legislator, in establishing in article 3, no. 1 who are the liable persons for the UCT, expressly and intentionally established that these are the owners (or in the situations provided for in no. 2, the persons enumerated there), considered as such the persons in whose names the same are registered.

c) It emphasizes that the legislator did not use the expression "presumed to be", as it could have done, for example, in the following terms: "the liable persons for the tax are the owners of the vehicles, presumed to be such the natural or legal persons, of public or private law, in whose names the same are registered".

d) The tax provision is full of provisions analogous to that established in the final part of no. 1 of article 3, in which the tax legislator, within its freedom of legislative conformation, expressly and intentionally establishes what should be considered legally, for purposes of scope, of income, of exemption, of determination and of periodization of taxable profit, for purposes of residence, of location, among many others.

e) The legislator established expressly and intentionally that those considered as such (as owners or in the situations provided for in no. 2, the persons enumerated there) are the persons in whose names [the vehicles] are registered, since it is this interpretation that preserves the unity of the legal-tax system.

f) This is a clear option of legislative policy embraced by the legislator, whose intention, within its freedom of legislative conformation, was that, for purposes of the UCT, those appearing as such in the motor vehicle registry be considered owners.

g) In sum, article 3 of the UCT Code does not comprise any legal presumption, and it is certain that the peregrine thesis advocated by the claimant directs its objective at the wrong target.

h) It is undeniable that the Property Registry Code applies subsidiarily to the Motor Vehicle Registry Regulation; however, the Property Registry Code is not subsidiary legislation to the UCT Code.

i) Therefore, the presumption of motor vehicle ownership derives solely, directly and exclusively from the motor vehicle registry regime itself and not from the tax legislation on motor vehicles which constitutes a collateral aspect of that regime.

j) Therefore, the rebuttal of the presumption of motor vehicle ownership necessarily must be directed to, or rather, against what is contained in the motor vehicle registry itself, and not against the mere tax effect that derives from the motor vehicle registry information as, in the end, the Claimant essentially seeks to do.

k) From the articulation between the scope of the subjective applicability of the UCT and the taxable event corresponding to the tax obligation, it follows unequivocally that only the legal situations subject to registration (without prejudice to the permanence of a vehicle in national territory for a period exceeding 183 days, provided for in no. 2 of article 6) generate the birth of the tax obligation.

l) The failure to update the registration, in accordance with the provisions of article 42 of the Motor Vehicle Registry Regulation, shall be imputable to the legal sphere of the liable person for the UCT and not to the Portuguese State, as the liable person for this Tax.

m) Even admitting that, from the standpoint of the rules of civil law and property registration, the absence of registration does not affect the acquisition of the quality of owner and that registration is not a condition of validity of contracts with real effect, in accordance with that established in the UCT Code (which in the case in question constitutes special law, which, according to general rules of law, derogates the general rule), the tax legislator intentionally and expressly wanted those considered as owners, lessees, purchasers with retention of title, or holders of the right of purchase option in long-term vehicle leasing, the persons in whose names (the vehicles) are registered.

n) In light of a teleological interpretation of the regime established throughout the Unique Circulation Tax Code, the interpretation advocated by the claimant to the effect that the liable person for the UCT is the actual owner, independently of not appearing in the motor vehicle registry, the registry of that quality, is manifestly erroneous, insofar as it is the proper ratio of the regime established in the UCT Code that constitutes clear proof that what the tax legislator intended was to create a Unique Circulation Tax based on the taxation of the owner of the vehicle as it appears in the motor vehicle registry.

o) All the reasoning advocated by the claimant is riddled with error, it not being possible to rebut the legal presumption established.

p) At no point did the claimant prove, with the rigor required of it, which vehicles were supposedly written off as total loss and in relation to which the respective registrations were cancelled; in none of the 9 appeal proceedings and now in the arbitral proceeding the claimant proves the supposed cancellation of the registrations.

q) The purported "sales invoices" are not an apt document to demonstrate the cancellation of the registrations; invoices are not apt to prove the conclusion of a bilateral contract such as a sale, as such documents do not, by themselves, reveal an indispensable and unequivocal declaration of intention (i.e., acceptance) by the purported purchasers.

r) The lack of bilateral character of the invoices could have been supplemented by proof of receipt of the price contained therein by the claimant, which it did not do.

s) It challenges all the invoices attached by the claimant, as serious doubts arise concerning their veracity, whether due to inconsistencies contained therein (date, location of registered office, company name, etc.), or due to discrepancies that they present when compared with the permanent certificate of the commercial registry.

t) It alleges, moreover, that either such certificate is false, or the invoices are false, which is raised for all legal purposes.

u) The interpretation conveyed by the claimant shows itself to be contrary to the Constitution, insofar as it violates the principle of trust and legal certainty, the principle of efficiency of the tax system and the principle of proportionality, in addition to entailing a violation of the no less important principles of trust and legal certainty.

v) In addition to being offensive to the principle of efficiency of the tax system, insofar as it results in an obstruction and increase in costs of the competencies assigned to the respondent, with obvious prejudice to the interests of the Portuguese State.

x) Furthermore, it argues that in no circumstance are the legal requirements met that confer the claimed right to compensatory interest.

z) Contending for the condemnation, in any circumstance, of the claimant for the payment of the costs arising from the present request for arbitral pronouncement, since it was not the respondent who gave rise to the filing of the same.

  1. The Arbitral Tribunal was duly constituted and is materially competent.

The parties possess standing and legal capacity and are legitimate (arts. 4 and 10, no. 2, of the same decree-law and art. 1 of Order no. 112-A/2011, of 22 March).

The proceedings are free from nullities.

1.3 UNPROVEN FACTS

No proof was made that the motor vehicles to which the disputed assessments relate were sold by the claimant.

1.4 THE LAW

The substantive question to be addressed resides in the interpretation to be given to no. 1 of art. 3 of the UCT Code in order to ascertain whether the rule concerning the scope of subjective applicability contained therein establishes a legal presumption juris tantum – and, as such, susceptible to rebuttal (as the claimant maintains) or, on the contrary, an express and intentional definition of personal scope, in the sense that the liable person for the tax is necessarily the one in whose name the motor vehicle is registered as owner.

Article 3, no. 1 of the UCT Code provides: "the liable persons for 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".

Based on the wording of this provision, the respondent – TCA – maintains that the basis of personal applicability that it defines does not today comprise any legal presumption, since what it transmits expressly and intentionally the thought of the tax legislator, in the sense of considering, in an irrefutable manner, as liable persons for the UCT the persons in whose names the motor vehicles are registered.

It advances in support of its thesis, hermeneutical reasons for the interpretation of law, appealing not only to its literality, but also to the systematic and teleological elements.

An invocation full of meaning, insofar as, in accordance with the provisions of art. 11 of the General Tax Law, "in determining the meaning of tax rules and in qualifying the facts to which they apply, the general rules and principles of interpretation and application of laws are observed". As referred to by Diogo Leite Campos, Benjamim Rodrigues, J. Lopes de Sousa – GTL 4th ed., in annotation to such article, "… without departing from the letter of the law, which must be the main reference and point of departure for the interpreter, its automatic application is excluded, assuming that in laws there is an operating rationality that the interpreter must strive to reconstruct".

It is, therefore, within this framework of interpretation of tax law, in this case art. 3, no. 1 of the UCT Code, that we must find the response to the antagonism of positions between the claimant and the TCA.

For the TCA, it is decisive for the determination of the liable person for the UCT the registration of ownership of the motor vehicle, so that the one in whose name it is registered will be considered as such, in an irreversible manner.

The registration of ownership of vehicles is, in accordance with the provisions of art. 5, no. 1, a) and no. 2 of Decree-Law 54/75, of 12 February, mandatory, so that any right of ownership that falls upon the vehicle is subject to registration, with the aim of ensuring the security of legal commerce, as well as the publicity of the legal situation thereof.

Such registration enjoys, in accordance with the provisions of art. 7 of the Property Registry Code (applicable to motor vehicle registration by virtue of art. 29 of the aforementioned Decree-Law 54/75), the "… presumption that the right exists and belongs to the registered owner, in the exact terms in which the registration defines it".

We therefore have that the entry of registration of ownership of the vehicle is, also itself, a presumption that the right of ownership over the same exists in the terms contained in the registration.

That is, the registration of motor vehicle ownership does not constitute any condition of validity of the contracts subject to it, in the same way as occurs with property registration (whose regime, as we have already noted, is extended to motor vehicle registration); registration has a merely declarative function.

It happens that art. 5, no. 1 of the Property Registry Code, imposes that "the facts subject to registration only produce effects against third parties after the date of their respective registration". From which it appears to result that this would suffice for the TCA to invoke the absence of registration to immediately cause art. 3, no. 1 of the UCT Code to function, demanding payment of the tax from the one in whose name the vehicle is registered, as the liable person for the tax.

It happens that no. 4 of art. 5 of the Property Registry Code restricts such understanding, by determining that "third parties, for purposes of registration, are those who have acquired from a common author rights incompatible with each other". Whence it follows that, by that means, the TCA would never be enabled to invoke the lack of registration, insofar as it does not meet the concept of third party.

Having set out these matters in general terms, we must ascertain whether, notwithstanding what has just been stated, no. 1 of art. 3 of the UCT Code contains, or does not contain, a legal presumption.

Everything is, in sum, a matter of determining whether the expression "considered as such", used therein, has the nature of a legal presumption.

It seems more or less evident that, both from the systematic and teleological perspective, the expression "considered as such", adopted in no. 1 of art. 3 of the UCT Code contemplates a true presumption, to which neither the apparent literality of the expression nor the tax order opposes.

To this end, refer Diogo Leite Campos, Benjamim Rodrigues, J. Lopes de Sousa – GTL 4th ed., in annotation to art. 73, page 651: "presumptions in matters concerning the scope of taxation may be explicit, revealed by the use of the expression 'presumed' or similar, as occurs, for example, in nos. 1 to 5 of art. 6, in subparagraph a) of no. 3 of art. 10, in art. 19 and 40, no. 1, of the Corporate Income Tax Code. Nevertheless, presumptions may also be implicit in rules concerning scope, in particular concerning objective scope, when certain values of movable or immovable assets are considered as constituting taxable matter, in situations in which it is not impossible to ascertain the actual value …", then enumerating a set of examples.

We understand that this is precisely the case contemplated by art. 3, no. 1 of the UCT Code: an implicit presumption, in this case, a presumption concerning subjective scope. A presumption, moreover, that has always existed in the realm of motor vehicle circulation tax, albeit previously defined in explicit form.

Now, no. 2 of art. 350 of the Civil Code establishes that legal presumptions may be rebutted by means of proof to the contrary, except in cases expressly provided for in law.

And, with regard to the rebuttal of presumptions, we consider good the doctrine to which the Supreme Court of Justice resorted in the grounds of Motion no. 1/91 of 03-04-1991 (Official Journal no. 114, of 18 May) – to classify as juris tantum a presumption established in a labor diploma – defended by Vaz Serra [Evidence (substantive evidentiary law), Law Journal 110-112, page 35], as well as by Mário de Brito (Annotated Civil Code, page 466) and Mota Pinto (General Theory of Civil Law, page 429): "… presumptions juris tantum constitute the rule, while presumptions iure et de iure are the exception. In case of doubt, the legal presumption is juris tantum, since it should not be considered, absent a reference in the law, that it was intended to prevent the production of proof to the contrary, imposing a formal truth to the detriment of actual proven fact".

In turn, within the scope of tax law, art. 73 of the General Tax Law provides that "the presumptions established in the rules concerning the scope of taxation always admit proof to the contrary". Which means that all presumptions in matters concerning the scope of taxation, such as that which no. 1 of art. 3 of the UCT Code establishes, are juris tantum and, as such, rebuttable.

Indeed, as far as the UCT is concerned, it would seem offensive to the unity of the legal-law system – and even, with the necessary adaptations, in opposition to nos. 2 and 3 of art. 11 of the General Tax Law - that an individual would be considered as not an owner of an asset for civil purposes and necessarily have to be one for tax purposes.

On the other hand, in fulfillment of the principles – with establishment in our community legal order – of the polluter-pays and equivalence principles, the UCT incorporates concerns of an environmental and energy nature, seeking that the costs resulting from environmental damage caused by the use of motor vehicles be borne by the actual owners (and not by the presumed owners).

To which is added the fact that the TCA must guide its activity by observance of the principles of legality, of inquisitorial investigation and discovery of actual truth, inherent to the constitutional dictate of contributory capacity.

Having set out these matters, let us then see whether, in the case in question, the claimant succeeded in proving that it was not the owner of the vehicles to which the assessments that are the subject of the present arbitral request relate, on the final dates of their respective payments.

The answer is in the negative.

The respondent calls into question, as a guiding principle, that invoices evidencing sales contracts are apt to prove the effective transfer of ownership of vehicles, an understanding which we do not share.

And, as regards objectively the invoices attached to the proceedings by the claimant, it directly challenged their content, pointing out several incongruities in their issuance (name, registered office, descriptive details, identification of sellers, etc.), concluding by invoking their falsity.

It is known that art. 342, no. 1 of the Civil Code, establishes as a general rule of evidence that "it falls to him who invokes a right to prove the constitutive facts of the alleged right".

Now, as follows from what has been set out above, we start here from a legal presumption (that which is established in art. 3, no. 1 of the UCT Code) which, as has been concluded, is rebuttable. The rebuttal of the legal presumption follows the provisions of art. 347 of the same CC, when it imposes that "full legal evidence can only be contradicted by means of evidence that shows the fact which is the object thereof to be untrue".

In turn, as regards counterevidence, it results from art. 346 of the same code that if the other party succeeds in rendering doubtful the facts for which evidence was presented, "the matter is decided against the party burdened with the proof".

Having examined the invoices attached to the appeal procedures, to which the claimant refers, concatenated with the incongruities invoked by the respondent, serious doubts persist as to the effective transfer of the vehicles to which the disputed assessments relate.

Thus, although we are inclined, in theory, to admit that sales invoices may constitute an apt means of proof (as we have already considered in other arbitral awards), given the serious doubts that the incongruities contained in the invoices in question raise for us, we must consider the transfer of vehicles alleged by the claimant as not proven. A conclusion that is based on the principle of freedom of appraisal of evidence in which the tribunal bases its conviction, formed from the examination and evaluation of the means of proof contained in the proceedings (art. 607, no. 5 of the Civil Procedure Code).

Accordingly, the claimant having failed to remove the legal presumption of subjective applicability of the UCT that weighs upon it, in view of the provisions of art. 3, no. 1 of the UCT Code, its claim necessarily fails, insofar as no censure can be directed at the disputed assessments.

  1. DECISION

In view of the foregoing, it is decided:

a) To judge the claim entirely unfounded, thereby absolving the Tax and Customs Authority;

b) To condemn the claimant for the payment of the costs of the proceedings.

VALUE OF THE PROCEEDINGS: In accordance with the provisions of art. 306, no. 2 of the Civil Procedure Code, art. 97-A, no. 1, a) of the Tax Procedure Code and art. 3, no. 2 of the Regulations on Costs in Tax Arbitration Proceedings, the value of the proceedings is fixed at €20,146.51 (twenty thousand one hundred and forty-six euros and fifty-one cents).

COSTS: In accordance with the provisions of art. 22, no. 4, of the Regulations on Costs in Tax Arbitration Proceedings, the amount of costs is fixed at €1,224.00 (one thousand two hundred and twenty-four euros), in accordance with Table I attached to the Regulations on Costs in Tax Arbitration Proceedings.

Let notice be given.

Frequently Asked Questions

Automatically Created

Who is the taxable person for IUC when a vehicle has been sold to a third party before the taxation period?
Under Article 3(1) of the IUC Code, the registered owner is considered the taxable person. However, this case challenges whether that provision creates an irrebuttable presumption. The claimant argued that when a vehicle has been sold before the taxation period, the registry creates only a rebuttable presumption of ownership (juris tantum). By providing sales invoices and proof of transfer dated before the 2014 tax period, the company sought to rebut this presumption and demonstrate that ownership had passed to third-party purchasers. Article 73 of the General Tax Law supports this interpretation by prohibiting irrebuttable presumptions in tax matters and requiring that presumptions concerning taxation scope always admit contrary proof. Therefore, substantive ownership rather than mere registry formality should determine IUC liability.
Can a vehicle trading company challenge IUC assessments through tax arbitration under RJAT?
Yes, vehicle trading companies can challenge IUC assessments through tax arbitration under the Legal Regime for Tax Arbitration (RJAT - Decree-Law 10/2011). In this case, the company first exercised its right to file gracious appeals (administrative appeals) which were dismissed by the Tax Authority. Following dismissal, Article 2(1)(a) and Article 10 of the RJAT allowed the company to request constitution of an arbitral tribunal to dispute the IUC assessments' legality. The arbitral tribunal was properly constituted on February 25, 2015, with an arbitrator appointed by the Deontological Council. This procedural path demonstrates that RJAT provides an alternative dispute resolution mechanism for companies to challenge tax assessments, including IUC, after exhausting or bypassing administrative remedies.
What happens when IUC is charged to the registered owner after the vehicle has already been transferred?
When IUC is charged to the registered owner after vehicle transfer, the former owner can challenge the assessment by rebutting the registry presumption. In this case, although the vehicles were sold and some written off as total losses before the 2014 taxation period, purchasers failed to register ownership transfers at the Motor Vehicle Registry Office, leaving the claimant appearing as the owner in the registry database. The claimant paid the €20,146.52 assessment to avoid enforcement proceedings and guarantee costs, then filed gracious appeals with supporting documentation (sales invoices and salvage records). The company argued that vehicle registration is declarative rather than constitutive, serving only publicity purposes, and that Article 64 of the Tax Procedure Code permits rebutting presumptions concerning taxation scope through gracious appeals against assessment acts based on such presumptions.
Is the taxpayer entitled to compensatory interest after annulment of unlawful IUC assessments?
Yes, the claimant specifically requested recognition of the right to compensatory interest in addition to restitution of the €20,146.52 tax paid. Portuguese tax law provides for compensatory interest when taxpayers suffer financial loss due to unlawful tax assessments subsequently annulled. If the arbitral tribunal rules in favor of the claimant and declares the IUC assessments illegal and annuls them, the Tax Authority would be required to refund the tax amount plus compensatory interest calculated from the payment date until restitution. This compensates taxpayers for the time value of money and financial prejudice suffered during the period funds were improperly held by the tax administration. The request for compensatory interest is a standard component of claims seeking annulment of unlawful tax assessments.
How does the CAAD interpret subjective incidence rules for IUC on vehicles sold by leasing and rental companies?
The case illustrates how the CAAD (Administrative Arbitration Center) interprets IUC subjective incidence rules for vehicle trading companies. The claimant advanced an interpretation that distinguishes between formal registry status and substantive ownership rights. For leasing and rental companies that frequently transfer vehicles, the interpretation of Article 3(1)'s phrase 'considered as such' is critical—whether it creates an absolute or rebuttable presumption. The company argued that IUC's underlying equivalence principle, which links tax liability to environmental and road costs from actual vehicle circulation, supports that non-owners who neither possess nor use vehicles shouldn't bear tax liability. This systematic interpretation considers IUC's environmental policy objectives alongside property law principles. However, the excerpt concludes before presenting the tribunal's legal analysis and ruling, so the final CAAD interpretation on whether companies can rebut registry-based liability through proof of prior sale remains undisclosed in this document portion.
