Process: 247/2014-T

Date: October 10, 2014

Tax Type: IUC

Source: Original CAAD Decision

Summary

In Process 247/2014-T, the Portuguese tax arbitration tribunal addressed the subjective incidence of the Unique Motor Vehicle Tax (IUC) for fiscal year 2008. The claimant, a financial credit institution, challenged 134 IUC assessments totaling €5,712.00 plus €999.55 in compensatory interest. The institution had incorporated two vehicle rental companies by merger in 2004, and the Tax Authority subsequently assessed IUC against it for vehicles registered to the extinct companies. The central legal dispute concerned whether Article 3(1) of the IUC Code establishes a rebuttable legal presumption or an irrebuttable legal fiction regarding vehicle ownership for tax purposes. The claimant argued that it had sold all disputed vehicles before the January 1, 2008 taxable event date, providing invoices as proof. It contended that the ownership presumption based on vehicle registration could be rebutted by demonstrating actual transfers of ownership through sales contracts, which have real effects under Portuguese law. The Tax Authority maintained that IUC liability attaches to whoever appears as the registered owner in the motor vehicle register, regardless of actual ownership, characterizing Article 3(1) as a legal fiction rather than a rebuttable presumption. The Authority questioned the probative value of the submitted invoices and argued that registration changes are mandatory for IUC liability purposes. The tribunal had to resolve fundamental questions about the relationship between registration formalities and substantive ownership rights, the effect of corporate mergers on tax obligations, and whether financial institutions with reservation of ownership or financial leasing arrangements qualify as IUC taxpayers when vehicles are subsequently sold.

ARBITRAL DECISION

I. REPORT

A, a company with registered office at ..., holder of the single registration and identification number for a legal entity ..., hereinafter designated as Claimant, submitted a request for constitution of an arbitral tribunal in tax matters and a request for arbitral ruling, under the provisions of articles 2 no. 1 a) and 10 no. 1 a), both of Decree-Law no. 10/2011, of 20 January (Legal Framework for Arbitration in Tax Matters, abbreviated as RJAT), petitioning for the annulment of 134 tax acts for assessment of Unique Motor Vehicle Tax (IUC) relating to the fiscal year of 2008, in the amount of € 5,712.00, and respective compensatory interest, in the amount of € 999.55.

To substantiate its request, it alleges, in summary:

a) On 30/11/2004, the Claimant incorporated by merger the following companies:

(i) B – Commerce and Vehicle Rental, Ltd.; and

(ii) C – Commerce and Vehicle Rental, Ltd.;

b) By virtue of the merger, the incorporated companies operated the global transfer of their assets to the incorporating company, here the Claimant;

c) The incorporated companies were extinguished on the date of the merger;

d) The incorporated companies were notified, in the capacity of IUC taxpayer, of the assessments now in dispute;

e) The Claimant is a financial credit institution, and within the scope of its activity, grants to its clients financing intended for the purchase of motor vehicles;

f) The financing is formalized either through the execution of loan agreements, in which, as security for payment of the loaned capital, the borrower grants to the lender a reservation of ownership of the acquired motor vehicle, or through financial lease agreements;

g) The Claimant was notified to exercise the right to prior hearing, as allegedly being the IUC taxpayer due in the fiscal year of 2008 and not yet assessed;

h) The Claimant exercised the right to prior hearing, and the Tax Authority proceeded to assess the tax in question, notifying the Claimant of the IUC assessment acts and respective compensatory interest;

i) The Claimant filed an administrative appeal against the tax acts of IUC assessment and respective compensatory interest;

j) The administrative appeals filed were subject to a dismissal decision;

k) The Claimant filed a hierarchical appeal against the act dismissing the administrative appeals filed by it, an appeal that was not subject to any decision, whereby its tacit dismissal is presumed;

l) The Claimant is not an IUC taxpayer as it was not the owner of the vehicles on the date of occurrence of the tax event;

m) All the disputed assessments relate to vehicles alienated on a date prior to the date of occurrence of the tax event;

n) Under the terms of article 3 of the CIUC, IUC taxpayers are the owners of vehicles, being equated to owners financial lessees, purchasers with reservation of ownership, as well as other holders of purchase option rights by virtue of a lease agreement;

o) The presumption established in article 3 no. 1 of the CIUC is a rebuttable presumption;

p) Thus, the IUC taxpayer is the owner, even if not registered in the motor vehicle register, as long as sufficient proof is made to rebut the legal presumption arising from the register;

q) The Tax Authority cannot be considered a third party for purposes of registration, by virtue of the fact that sales and purchase contracts would be unenforceable against it;

r) The contract for purchase and sale of a motor vehicle has real effect, the transfer of ownership operating by mere effect of the contract.

The Claimant attached 13 documents and did not call any witnesses.

After the submission of the request for constitution of the arbitral tribunal, the Claimant attached the draft decision of an administrative appeal filed by it, relating to IUC assessments for the fiscal year of 2008.

In the request for arbitral ruling, the Claimant opted not to appoint an arbitrator, whereby, under the terms of article 6 no. 2 a) of the RJAT, the signatory was appointed by the Deontological Council of the Administrative Arbitration Center, the appointment having been accepted in accordance with the legally provided terms.

The collective arbitral tribunal was constituted on 19 May 2014.

Notified under the terms and for the purposes of article 17 of the RJAT, the Respondent submitted a response, alleging, in summary, the following:

a) Article 3 of the CIUC does not establish any presumption of ownership, but a true legal fiction – the legislator does not say that they are presumed to be owners but that they are considered to be owners;

b) The failure to register the changes of ownership in the register has as a consequence that the obligation to pay the IUC falls upon the registered owner, the Tax Authority being unable to assess the tax on the basis of elements that do not appear in the register;

c) The IUC is due by the persons who appear in the register as owners of the vehicles;

d) The invoices attached by the Claimant as proof of the execution of the sales and purchase contract are not apt to make such proof;

e) Several of the invoices are irregularly issued, whereby they cannot be accepted as a means of proof;

f) As for the vehicle with registration number ...-...-..., the Claimant did not attach any invoice.

The Respondent attached 1 document and a copy of the administrative file, having called no witness.

The meeting referred to in article 18 of the RJAT, as well as the production of oral and written allegations, was dispensed with, without opposition of the parties, given the fact that, on the one hand, no matters susceptible of discussion at the said meeting were raised and, on the other hand, the file contained all the documentary elements necessary and sufficient to decide the matter of law.

II. PRELIMINARY DETERMINATION:

The Arbitral Tribunal was regularly constituted and is materially competent.

There are no nullities that invalidate the proceedings.

The request for constitution of the Arbitral Tribunal was submitted within the period provided for in article 10 no. 1 a) of the RJAT, calculated from the date on which the tacit dismissal is presumed, due to non-compliance with the 60-day period for decision of the hierarchical appeal, provided for in article 66 no. 5 of the Tax Procedure and Process Code, whereby it is timely.

The parties have legal personality and capacity and are legitimate, with no defects in representation.

There are no exceptions or preliminary questions that preclude consideration of the merits and which must be considered ex officio.

III. ISSUES FOR DECISION:

The issues for decision are as follows:

(i) to determine whether the rule of subjective incidence provided for in article 3 no. 1 of the CIUC provides for a rebuttable presumption or, instead, a legal fiction, insusceptible, therefore, of being rebutted by proof to the contrary;

V. LAW:

a. Interpretation of article 3 no. 1 of the CIUC:

The Claimant invokes that, with respect to the 134 disputed IUC assessments, the requirements of subjective incidence provided for in article 3 of the CIUC are not met, and is not, therefore, an IUC taxpayer.

To this end, it alleges, in summary, that article 3 of the CIUC establishes an implicit presumption of ownership of vehicles in favor of those in whose names they are registered, a presumption that, by virtue of the application of the general rule provided for in article 73 of the General Tax Law, is rebuttable by proof to the contrary.

For its part, the Respondent defends that article 3 of the CIUC does not establish any implicit presumption, but a true legal fiction, irrebuttable, therefore, by proof to the contrary.

Given the position of the parties, let us examine what should be, in accordance with the rules of legal hermeneutics established, the interpretation of article 3 no. 1 of the CIUC.

Article 3 no. 1 of the CIUC provides:

"The taxpayers of the tax are the owners of vehicles, being considered as such the natural or legal persons, of public or private law, in whose names they are registered.

From simple reading of the first paragraph of the said provision, it is verified, without great difficulty, that the crux of the matter lies in the expression "considered as" used by the legislator.

Given the terminology used, should it be understood that the legislator intended to establish an implicit presumption or a true legal fiction?

For consideration of this question, it is important, first of all, to bring here some legal concepts and legal definitions.

Thus,

Under the terms of article 349 of the Civil Code, presumptions are the inferences that the law or the judge draws from a known fact to establish an unknown fact.

With respect to legal presumptions, article 350 no. 2 of the same Code prescribes that these may be rebutted by proof to the contrary, except in cases where the law prohibits it.

As for, in concreto, tax incidence presumptions, article 73 of the General Tax Law establishes that these always admit proof to the contrary.

Beyond presumptions, the legislator also resorts to the so-called "legal fictions," which translate into "a legal process that considers a situation or a fact as different from reality in order to attribute legal consequences to it"[1].

According to the thesis advanced by the Respondent, the fact that article 3 no. 1 of the CIUC establishes that they "are considered" to be owners, rather than "are presumed" to be owners, reveals that the legislator, within its freedom of legislative conformity, intended expressly to determine that the persons in whose names the vehicles are registered are considered, without admissibility of any proof to the contrary, to be owners thereof.

Also according to the Respondent, if the legislator intended to create a presumption and not a legal fiction, it would have written, as it does in various other statutes, that they are presumed to be owners and not that they are considered to be owners.

We may already state that this tribunal does not support the understanding defended by the Respondent.

This is because, by analysis of the historical and teleological elements, beyond, naturally, the literal element of legislative interpretation, we will inevitably reach the conclusion that the legislator did not intend to establish any legal fiction but only and solely a presumption, rebuttable by proof to the contrary under the terms and for the purposes of article 73 of the General Tax Law.

Consider the following:

As to the historical element, it is important to note that the current IUC had its genesis in the creation, through Decree-Law 599/72, of 30 December, of the motor vehicle tax.

This motor vehicle tax, which remained in force until the creation of the current CIUC, expressly established that the tax is due by the owners of vehicles, being presumed to be such the persons in whose names they are registered or recorded – see article 3 of the Regulation of the Motor Vehicle Tax, attached to the said Decree-Law 599/72, of 30 December.

Upon approval of the new CIUC, the legislator replaced the expression "being presumed to be such" with the expression "being considered as such," but this cannot be defended as meaning a true substitution of a presumption (rebuttable) for a legal fiction (irrebuttable).

This is because, as JORGE LOPES DE SOUSA teaches[2], in tax incidence matters, presumptions can be revealed by the expression "it is presumed" or by a similar expression. By way of example, the author points out that article 40 no. 1 of the CIRS uses the expression "it is presumed," whereas article 46 no. 2 of the same Code uses the expression "is considered," with no difference between one and the other expression, both meaning, after all, the same thing: a legal presumption.

The same occurred with the CIUC in which, although the expression "it is presumed" was changed, in relation to the original wording, by the expression "is considered," no substantive change was produced, the different expressions having exactly the same meaning.

We reach the very same conclusion by analysis of the teleological element.

Indeed, it is important to bear in mind the explanatory statement of Bill no. 118/X of 07/03/2007, underlying Law no. 22-A/2007, of 29 June.

Having analyzed this explanatory statement, it is verified that what was intended was to undertake a "global and coherent reform of taxes related to the acquisition and ownership of motor vehicles" which results from the "imperative necessity of bringing clarity and coherence to this area of the tax system and the necessity, more imperative still, of subordinating it to the principles and concerns of an environmental and energy nature that today mark the discussion of motor vehicle taxation."

Continuing, the said explanatory statement explains that "the two new taxes now created, the motor vehicle tax and the unique motor vehicle circulation tax, constitute much more than the technical continuation of the figures created in the 70s and 80s that preceded them, aimed predominantly at raising revenue, indifferent to the social cost resulting from motor vehicle circulation. They constitute something different, figures already of the century in which we live, with which it is certainly intended to raise public revenue, but to raise it in the measure of the cost that each individual causes the community."

Which led, moreover, to the consecration of the principle of equivalence, enshrined in article 1 of the CIUC, "thereby making clear that the tax, as a whole, is subordinated to the idea that taxpayers should be burdened in the measure of the cost they cause to the environment and road network, this being the reason for the existence of this tax figure. It is this principle that dictates the burden on vehicles according to their respective ownership and up to the moment of deregistration."

The IUC, as a true environmental tax, has, therefore, as its taxpayer the polluter, being nothing more, after all, than the consecration of the polluter-pays principle.

By which it is verified that the structuring principle of the reform of motor vehicle taxation is precisely the incidence of taxation on the true user of the vehicle, a principle that does not align with the "blind" reading of the letter of the law, which could, after all, lead to taxing someone who is not the owner and, in this way, someone who is not the subject causing the "environmental and road cost" provoked by the vehicle, to which article 1 of the CIUC refers.

From all that has been exposed, it results that the literal, historical, and teleological elements of interpretation of the law necessarily lead to the conclusion that the expression "considered as" has exactly the same meaning as the expression "presumed to be," and should, therefore, be understood that article 3 no. 1 of the CIUC consecrates a true presumption of ownership and not any fiction, and is therefore such presumption rebuttable.

Under the terms of article 3 no. 1 of the CIUC, the taxpayer of the tax is, in principle, the owner, since the law presumes that it is this person who uses the good. But if it is proven that, after all, it is not the owner who makes use of the vehicle, but a third party, then this person will, inevitably, be the taxpayer of the tax.

This is, to the best of our understanding, the interpretation that is in harmony, on the one hand, with the principle enunciated in article 11 no. 3 of the General Tax Law, that, in cases of doubt about the interpretation of tax rules, "attention must be paid to the economic substance of tax facts," and, on the other hand, with the principle of equality in the distribution of public burdens, which requires that the taxation of the generality of taxpayers, whenever possible, be based on the economic reality underlying the tax facts[3].

Indeed, any other interpretation would violate, immediately, the aforementioned principle of equivalence enshrined in article 1 of the CIUC, under the terms of which it is established that the IUC seeks to "burden taxpayers in the measure of the environmental and road cost that these cause, in implementation of a general rule of tax equality."

b. The legal value of motor vehicle registration:

Under the terms of article 1 no. 1 of Decree-Law 54/75, of 12 February, which established the Motor Vehicle Property Register, "vehicle registration has essentially as its purpose to publicize the legal situation of motor vehicles and their trailers, with a view to the security of legal commerce."

For its part, article 7 of the Land Registry Code, supplementary legislation of the motor vehicle registry, prescribes that "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."

As is well known, property registration does not have a constitutive nature, but merely declarative, allowing only the inscription in the register to presume the existence of the right and its ownership. Note, presume, and not fictionally create, which means that the presumption resulting from the register can be rebutted by proof to the contrary.

And this is so precisely because, under the terms of article 408 of the Civil Code, except for the exceptions provided for in the law, the constitution or transfer of real rights over a determined thing is effected by mere effect of the contract, its validity not depending on inscription in the register.

In the case of a contract for purchase and sale of a motor vehicle, the law not providing any specific exception for it, the contract has real effect, the purchaser becoming its owner, independently of the register.

Now, in the same way that the purchaser becomes the owner independently of the register, so too the registered holder ceases to be the owner, despite still appearing in the register as such.

Note that, in the present case, despite the failure to register in the register, the transfers carried out are enforceable against the Respondent, notwithstanding what is provided in article 5 no. 1 of the Land Registry Code, which provides that facts subject to registration only produce effects against third parties when registered.

This is because the Respondent is not, for purposes of this article, considered a third party for purposes of registration.

The notion of third parties for purposes of registration is established in article 5 no. 4 of the same article: third parties, for purposes of registration, are those who have acquired from a common author incompatible rights, which is manifestly not the case in the present proceedings.

In the present case, the companies incorporated by the Claimant appear in the register as owners of the vehicles subject to the disputed assessments, despite the Claimant's allegation that it is not, on the date of the tax event, the owner thereof, because they have already been alienated.

Since the presumption resulting from the register is, as we have seen, rebuttable, let us examine whether the documents attached by the Claimant are apt to rebut such presumption.

c. The probative value of the invoices attached by the Claimant:

In order to prove that 134 of the vehicles whose assessments are at issue in the present proceedings were alienated on a date prior to the birth of the tax event, the Claimant attached the respective sales invoices.

Note that the Respondent alleged that, with respect to the vehicle with registration number ...-...-..., the Claimant did not attach any sales invoice; as for the invoices attached to prove the alleged alienation of the other vehicles, it invoked that "an invoice is not apt to prove the execution of a synallagmatic contract such as a purchase and sale, since that document does not reveal by itself an essential and unequivocal declaration of intent (i.e., acceptance) on the part of the alleged purchaser" (see article 87 of the response).

As for the first question – failure to attach an invoice relating to the vehicle with registration number ...-...-... – having collated all documents attached to the proceedings, it is verified that, in effect, the Claimant did not attach any sales invoice, whereby, with respect to this vehicle, naturally the Claimant's claim will have to fail, due to evident lack of proof relating to the alienation of its ownership.

Let us therefore examine whether the Respondent is right as to the alleged lack of probative value of the invoices attached by the Claimant.

As results from the proven facts, none of the 134 vehicles in question in the present proceedings belong to categories F or G referred to in article 4 of the CIUC, whereby the tax event occurs on the date of their registration or on each of their anniversaries.

It also results from the proven facts that, on the date of occurrence of the tax event, an invoice for sale to a third party had been issued by the companies incorporated by the Claimant with respect to each of the 133 vehicles.

The Respondent argues that the invoice is not a suitable document to prove the sale of the vehicle, being nothing more than a document unilaterally issued by the Claimant, arguing that "as is public knowledge, there is no lack of cases of issuance of invoices relating to transfers of goods and/or provision of services that never occurred" (see article 88 of the response).

It is certain, as the Respondent invokes, that there are many situations in which invoices do not evidence any legal transaction.

In the present case, however, no element permits us to conclude that the invoices attached do not evidence any transaction, it being certain that their falsity was not even alleged by the Respondent, which limited itself to invoking that there are various such situations, without specifically referring that the situation in the present case was subsumed to such.

Whereby, in the absence of any elements or grounds that permit us to conclude otherwise, we must, naturally, accept the veracity of the documents attached.

All the more so that, as is well known, the declarations of taxpayers presented in accordance with the law and the data and determinations recorded in their accounts or accounting records enjoy a presumption of veracity and good faith, under the terms of article 75 of the General Tax Law.

A presumption which, like the other presumptions analyzed in these proceedings, is rebuttable by proof to the contrary, it being certain that the Respondent has not succeeded in rebutting this presumption (nor in good rigor attempted to).

Once the veracity of the invoices attached by the Claimant is established, we must consider, without need for any other considerations, these to be documents apt to prove the alienation of the vehicles in question.

Indeed, the law not providing any specific form for the execution of a contract for purchase and sale of movable property, one must necessarily accept as proof of the said contract the invoice issued in accordance with legal requirements.

By which it is verified that, on the date of the tax event (date of registration or of each of its anniversaries), the Claimant had alienated 133 of the 134 vehicles whose assessments were disputed, despite the said alienations not having been subject to registration in the register.

Thus, given the fact that, as already stated, the presumption resulting from the register is rebuttable by proof to the contrary, proof that is considered sufficient with the presentation of the sales invoices of the vehicles, it is verified that, with respect to these 133 vehicles, the Claimant is not their owner, and is not therefore an IUC taxpayer for the assessed tax.

VI. RULING:

In view of the foregoing, it is decided:

a) to uphold the request for declaration of illegality of 133 IUC assessment acts relating to the fiscal year of 2008, in the amount of € 5,684.00, as well as the respective compensatory interest, in the total amount of € 994.32, with all legal consequences;

b) to dismiss the request for declaration of illegality of the IUC assessment act relating to the vehicle with registration number ...-...-... (assessment no. 2008 ...), in the amount of € 28.00, as well as the respective compensatory interest, in the amount of € 5.23.

The value of the proceedings is fixed at € 6,711.55, in accordance with article 97-A no. 1 a) of the Tax Procedure and Process Code, applicable by virtue of subparagraphs a) and b) of article 29 no. 1 of the RJAT and article 3 no. 2 of the Regulation of Costs in Tax Arbitration Proceedings.

The value of the arbitration fee is fixed at € 612.00, by application of Table I of the Regulation of Costs in Tax Arbitration Proceedings, under the terms of articles 12 no. 2 and 22 no. 4, both of the RJAT, and article 4 no. 4 of the said Regulation, to be paid by the Parties in proportion to their respective loss of the action (3.03% for the Claimant and 96.97% for the Respondent).

Frequently Asked Questions

Automatically Created

Who is the taxable person for IUC when vehicles are financed through reservation of ownership or financial leasing?
Under Article 3 of the IUC Code, the taxable person is the vehicle owner, with financial lessees and purchasers under reservation of ownership agreements being legally equated to owners for IUC purposes. However, the key dispute in this case concerns whether this creates a rebuttable presumption or an absolute legal fiction. The claimant financial institution argued that once vehicles financed through reservation of ownership or financial leasing are sold to third parties, the institution is no longer the IUC taxpayer, as actual ownership has transferred. The Tax Authority contended that whoever appears as the registered owner in the vehicle register remains liable for IUC regardless of subsequent sales.
Can a financial institution be assessed IUC for vehicles it no longer owned at the date of the taxable event?
The claimant argued that a financial institution should not be assessed IUC for vehicles it no longer owned at the January 1, 2008 taxable event date, having provided invoices documenting sales prior to that date. The institution contended that Article 3(1) of the IUC Code establishes a rebuttable legal presumption of ownership that can be overcome through proof of actual transfer of ownership. Under Portuguese civil law, sales contracts for vehicles have real effects, with ownership transferring by mere effect of the contract. However, the Tax Authority maintained that the failure to register ownership changes means IUC liability remains with the registered owner, arguing that registration creates a legal fiction rather than a rebuttable presumption for tax assessment purposes.
How does a corporate merger by incorporation affect IUC tax liability for vehicles registered to extinct companies?
A corporate merger by incorporation results in the universal transfer of assets and liabilities from the incorporated (extinct) companies to the incorporating company. In this case, the claimant incorporated two vehicle rental companies (B and C) in 2004 through merger. When the Tax Authority subsequently assessed IUC for fiscal year 2008 against the extinct companies, the claimant as legal successor became responsible for challenging those assessments. The merger created legal succession, meaning the incorporating company inherited both the assets (vehicles) and any associated tax obligations or liabilities of the incorporated entities, including the right to contest IUC assessments originally directed to the now-extinct companies.
What legal remedies are available to challenge IUC assessments before Portuguese tax arbitration tribunals?
To challenge IUC assessments before Portuguese tax arbitration tribunals, taxpayers must first exhaust administrative remedies by filing an administrative appeal (reclamação) against the assessment acts. If dismissed, the taxpayer may file a hierarchical appeal (recurso hierárquico). If the hierarchical appeal is expressly rejected or tacitly dismissed (by the Tax Authority's failure to decide within 60 days), the taxpayer may then request constitution of an arbitral tribunal under Article 10(1)(a) of Decree-Law 10/2011 (RJAT). The arbitration request must be filed within 90 days. In this case, the claimant followed this entire procedural sequence before obtaining arbitral review of 134 IUC assessments plus compensatory interest.
Does the legal presumption of ownership in vehicle registration override the actual transfer of property for IUC purposes?
This case presented a fundamental conflict between registration formalities and actual ownership. The Tax Authority argued that the legal presumption of ownership based on vehicle registration operates as an irrebuttable legal fiction for IUC purposes, with the registered owner being liable regardless of actual transfers. The claimant countered that Article 3(1) of the IUC Code creates only a rebuttable presumption, not a legal fiction, emphasizing that sales contracts have real effects under Portuguese law with ownership transferring by contract rather than registration. The claimant argued the Tax Authority is not a 'third party' protected by registration requirements and cannot ignore proof of actual ownership transfers. The resolution of whether registration creates a conclusive fiction or a rebuttable presumption determines whether invoices and sales contracts can override registration records for IUC assessment purposes.
