Process: 227/2014-T

Date: September 26, 2014

Tax Type: IUC

Source: Original CAAD Decision

Summary

This CAAD arbitration case (Process 227/2014-T) addresses the critical issue of IUC (Imposto Único de Circulação - Single Vehicle Tax) liability in financial leasing arrangements. A..., S.A., a credit institution engaged in automotive financing through financial lease contracts, challenged four IUC assessments totaling €142.70 for tax years 2010 and 2012. The company had acquired the asset portfolio of B... de Crédito S.A. and assumed legal positions in various lease contracts. The core dispute centers on subjective tax incidence under Article 3(1) of the IUC Code: who bears IUC liability when vehicles under financial lease are sold to lessees who exercise their purchase option by paying the residual value, but fail to register the ownership transfer with the Motor Vehicle Registry Office (Conservatória do Registo Automóvel)? The Claimant presented invoices proving vehicle sales occurred before the disputed tax periods, arguing they should not be liable as they were no longer the actual owners. However, the Tax Authority assessed IUC against the financial company because registry records still showed them as registered owners, invoking the registration presumption. This case exemplifies the tension between formal registration requirements and economic reality in financial leasing transactions, with significant implications for financial institutions' tax obligations and the evidentiary weight of unilateral documents versus official registry data in rebutting legal presumptions under Portuguese tax law.

Arbitral Decision

Claimant: A..., S.A.

Respondent: Tax and Customs Authority.

I - REPORT

  1. On 6 March 2014, the company A..., S.A., holder of the Tax Identification Number (NIPC) …, with registered office at Rua …, in …, (hereinafter referred to as the "Claimant") requested the constitution of an arbitral tribunal, pursuant to the provisions of Articles 2 and 10 of Decree-Law No. 10/2011, of 20 January (Legal Regime for Arbitration in Tax Matters, hereinafter referred to only as "RJAT").

  2. The request for constitution of the arbitral tribunal was accepted by the Distinguished President of CAAD on 7 March 2014, and notified on 10 March 2014 to the Tax and Customs Authority (hereinafter referred to as "Tax Authority" or "Respondent").

  3. The Claimant seeks a ruling from the Arbitral Tribunal with a view to declaring the illegality and consequent annulment of 4 (four) assessment acts for the Single Vehicle Tax (IUC) for the years 2010 and 2012 concerning 4 (four) vehicles identified in Annex A attached to the initial petition, in the total amount of € 142.70 (one hundred and forty-two euros and seventy cents) and the reimbursement of that amount plus compensatory interest.

  4. In the request for arbitral ruling, the Claimant chose not to appoint an arbitrator. Pursuant to subparagraph (a) of Article 6(2) and subparagraph (b) of Article 11(1) of the RJAT, as amended by Article 228 of Law No. 66-B/2012, of 31 December, the Deontological Council of CAAD appointed as arbitrator of the single arbitral tribunal the Distinguished Dr. Olívio Mota Amador, who, within the applicable time period, communicated acceptance of the appointment.

  5. The parties were notified on 23 April 2014 of the appointment of the arbitrator and did not express any intention to challenge the arbitrator's appointment, in accordance with Article 11(1), subparagraphs (a) and (b) of the RJAT and Articles 6 and 7 of the Deontological Code.

  6. In accordance with the provisions of subparagraph (c) of Article 11(1) of the RJAT, as amended by Article 228 of Law No. 66-B/2012, of 31 December, the Arbitral Tribunal was constituted on 12 May 2014.

  7. On 6 June 2014, the Respondent, duly notified for that purpose by order of 12 May 2014, submitted its Response.

  8. On 2 July 2014, the Claimant submitted to the Arbitral Tribunal a request stating that the Respondent failed to submit its Response within the prescribed time period and requesting the waiver of the meeting provided for in Article 18 of the RJAT, pursuant to subparagraph (c) of Article 16 of the RJAT, and of the presentation of arguments.

  9. By order of 18 July 2014, the Arbitral Tribunal admitted the request identified in the preceding point to the case file and ordered notification of the Respondent.

  10. The Respondent, on 21 July 2014, agreed to the waiver of the holding of the meeting under Article 18 of the RJAT and the presentation of arguments and commented on the alleged untimeliness of the Response, considering that it had been notified to present the response by order of the Arbitral Tribunal of 12 May, therefore the 30-day period to contest would only expire on 12 June, whereas the response was submitted on 6 June, being clearly timely.

  11. By order of the Arbitral Tribunal of 23 July, which is hereby fully reproduced herein, the holding of the meeting provided for in Article 18 of the RJAT and the presentation of arguments were waived.

  12. On 22 September 2014, the Respondent requested the attachment to the case file of the arbitral decisions rendered in the context of proceedings No. 150/2014-T and No. 220/2014-T, decisions which concluded that invoices – as unilateral documents – do not possess sufficient probative value for the purposes of rebutting the registration presumption. By order of 25 September 2014, the Arbitral Tribunal admitted the attachment of these documents to the case file and ordered notification of the Claimant.

II – PRELIMINARY MATTERS

  1. The arbitral tribunal is materially competent and is regularly constituted, in accordance with the provisions of Articles 2(1), subparagraph (a), 5(2), and 6(1) of the RJAT.

The parties have legal standing and legal capacity, are legitimate and are duly represented, in accordance with Articles 4 and 10 of the RJAT and Article 1 of Regulation No. 112-A/2011 of 22 March.

The Respondent's Response, contrary to what was claimed by the Claimant on 2 July 2014, is timely, because the Respondent was notified to submit the response on 12 May 2014 and delivered said response on 6 June 2014, thus the 30-day period was respected.

The case does not suffer from any defects that would invalidate it.

In these terms, there is no obstacle to the consideration of the merits of the case.

Considering the identity of the tax facts and the factual and legal grounds invoked, nothing prevents, in light of the provisions of Article 104 of the CPPT and Article 3 of the RJAT, the cumulation of claims verified in the present case.

III – FACTUAL MATTER

  1. Established Facts

Based on the documentary evidence attached to the case file, the following facts are considered established:

H) The purchasers of the vehicles referred to in the preceding subparagraph had not, at the date of the tax events, registered the acquisitions with the Motor Vehicle Registry Office (Conservatória do Registo Automóvel), so that, in its database, the Respondent continued to appear as owner thereof.

  1. Unestablished Facts

There are no facts relevant to the decision that have not been established.

IV – MATTERS OF LAW

  1. In light of the subject-matter of the present proceedings, the central question to be considered is whether, for the purposes of the provisions of Article 3(1) of the Single Vehicle Tax Code (CIUC), the taxpayer of the IUC is the lessor or the new owner, if it is verified that, on the date of the occurrence of the taxable event, the vehicle had been previously disposed of, but continues to be registered in the name of the lessor (its previous owner).

  2. The factual matter is established (see, above, No. 14) and we now determine the applicable law to the underlying facts in accordance with the question already stated (see, above, No. 16).

  3. The arbitrator in the present proceedings has already rendered three arbitral decisions in proceedings No. 174/2014-T, 120/2014-T and 140/2014-T on an identical question to that presented in the present proceedings. The existence of an identical merits question in a new proceeding can always give rise to a change in the position previously adopted, because from the new adversarial proceeding may result a deepening of the analysis and a reconsideration of the matters of law.

  4. From the present proceedings, despite the respect that the argumentative effort demonstrated by the Respondent deserves and the existence of the arbitral decisions rendered in proceedings No. 150/2014-T and No. 220/2014-T, attached to the present proceedings by the Respondent, no elements result that would justify a change in the position that I subscribed to in the arbitral decisions rendered in the proceedings identified in the preceding number.

  5. Article 3 of the CIUC provides as follows:

"Article 3

Subjective Scope of Charge

1 - The taxpayers of the tax are the owners of the vehicles, meaning those natural or legal persons, under public or private law, in whose name the same are registered.

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

It is important to clarify whether the provision contained in Article 3(1) of the CIUC admits or not that the person in whose name the vehicle is registered with the Motor Vehicle Registry Office may demonstrate, through the means of evidence admitted in law, that he/she is not the owner of the vehicle in the period to which the tax relates and, in this manner, set aside the tax obligation that rests upon him/her.

Article 3(1) of the CIUC does not use the term "presume" (presumem-se), which appeared in the extinguished Vehicle Tax Regulation, and replaced it with "considered as" (considerando-se). Does this semantic change by the legislator, by having opted for the word "considered as", prevent the existence of a presumption?

The literal interpretation of Article 3(1) of the CIUC alone cannot be considered entirely decisive and must be accompanied by other elements that reveal the true meaning of the provision in question.

  1. Presumptions are defined, in accordance with Article 349 of the Civil Code, as "... inferences that the law or the judge draws from a known fact to establish an unknown fact."

In accordance with the provisions of Article 73 of the LGT, the presumptions contained in the provisions of tax incidence always admit proof to the contrary.

The provision of Article 3(1) of the CIUC has the structure of a presumption provision as defined in the Civil Code. Indeed, it is verified that the law draws from the known fact, that is, the ownership of the vehicle contained in the motor vehicle registry, the presumption about the taxpayer who must bear the burden of the IUC. It happens, however, that it will always be possible for the subject that appears in the registry to set aside the application of the incidence provision, provided that he/she proves that the taxpaying capacity that justifies the tax imposition belongs to another, for example, due to the existence of the sale of the vehicle at a time prior to the occurrence of the tax event.

In sum, the provision of Article 3(1) of the CIUC contains a presumption of subjective incidence with respect to the owner of the vehicle as registered with the Motor Vehicle Registry Office, which, obviously does not exclude the possibility of proof to the contrary.

  1. The presumptions of tax incidence may be rebutted through the means provided for in Article 64 of the CPPT or, alternatively, through the administrative appeal procedure or judicial challenge of the tax acts based thereon.

In the present case, the request for constitution of an arbitral tribunal is the proper means to rebut the presumption of subjective incidence of the IUC that supports the tax assessments whose annulment is the object of the request, as this is a matter that falls within the competence of this arbitral tribunal, in accordance with Articles 2 and 4 of the RJAT.

  1. In the present proceedings, the vehicles with respect to which the IUC payment was pending were sold on a date prior to that to which the tax relates, but the purchasers of said vehicles had not, at the date of the tax events, registered the acquisitions with the Motor Vehicle Registry Office, so that, in its database, the Respondent continued to appear as owner thereof (see subparagraphs G) and H) of No. 14.)

Due to the execution of the sale and purchase contract, the full owner passes to be directly covered by Article 3(1) of the CIUC.

In accordance with case law, it is clear that, in light of the provisions of Article 408(1) of the Civil Code, the creation or transfer of real rights over a determined thing occurs by mere effect of the contract, except for exceptions provided by law. This is the case of the sale and purchase contract of a motor vehicle (Articles 874 and 879, subparagraph (a) of the Civil Code), which does not depend on any special formality, being valid even when concluded in verbal form.

The right of ownership of motor vehicles is subject to registration, in accordance with the provisions of Decree-Law No. 54/75, of 12 February, as subsequently amended, and whose purpose, in accordance with Article 1(1), consists of "...giving publicity to the legal situation of motor vehicles and their trailers, with a view to the security of legal commerce".

The lack of registration does not affect the validity of the sale and purchase contract, but only its effectiveness, and even this, only vis-à-vis third parties acting in good faith for the purposes of registration.

In conclusion, the registration of the acquisition of ownership by the lessees does not have constitutive value, but only a declarative value, that is, the buyer becomes owner of the sold vehicle by mere effect of the sale and purchase contract, independently of the respective registration.

Once the sale and purchase contract of the vehicle in favor of the lessee is executed, the lessee acquires ownership thereof by mere effect of the contract and concomitantly the status of taxpayer of the IUC, now no longer as a lessee holding a purchase option, but as full owner.

If the owner does not immediately register the ownership of the vehicle in his/her name, it is presumed that ownership continues to belong to the seller, but that presumption is relative, that is, it may be set aside by proof to the contrary.

  1. In the factual context of the present arbitral proceedings, it results that the sale of the vehicles in question was effected in years prior to those to which the tax relates (see subparagraphs D) and G) of No. 14). From the elements contained in the case file, it is verified that on the date of the taxability of the tax to which the assessments in question relate, the Claimant was not the owner of the vehicles identified, as the respective transfers of ownership had previously taken place, in accordance with civil law.

The means of evidence presented by the Claimant, consisting of copies of the sales invoices/receipts (see subparagraph G) of No. 14.), enjoy a presumption of truthfulness which is conferred upon them in accordance with Article 75(1) of the LGT. Thus, these documents appear to be suitable and with sufficient force to rebut the presumption upon which those assessments are based. Besides, the Respondent did not argue facts that, if they fall within the subparagraphs of Article 75(2) of the LGT, would set aside the presumption of truthfulness concerning said documents.

With respect to the means used by the Claimant to prove the sale of the vehicle, three aspects merit emphasis.

First, considering that the law does not require written form for this type of contract, the proof of the sale of the vehicle may be made by any means, namely by testimonial or documentary evidence. There are no legal restrictions on documentary evidence consisting of the presentation of an invoice/receipt for the sale of the vehicle. Thus, the presumption resulting from the registry is set aside through these documents (invoice/receipt for the sale of the vehicle) and the Tax Authority cannot come to require payment of the IUC from the seller. Except if the Tax Authority invokes sufficiently grounded reasons that put into question the authenticity of the invoices/receipts for the sale of the vehicles, which does not occur in the present proceedings.

Second, if VAT was levied on the sale of the vehicle, having been sufficient as proof of the transmission, the invoice/receipt of the sale, then it cannot afterwards come to question the probative value of that same document for the purposes of the IUC.

Finally, through the presentation of an invoice/receipt for the sale of the vehicle, the Tax Administration becomes aware that a transmission of the vehicle occurred, regardless of whether the seller registered the purchase or not. In this case, respect for the principles of good faith, justice and impartiality imposes, in our view, that the Tax Administration not ignore the transmission that occurred and refrain from requiring payment of the IUC from the seller.

  1. As a consequence of the foregoing, the assessments that are the subject of the present arbitral proceedings must be annulled with the consequent restitution of the tax improperly collected from the Claimant.

  2. The Claimant also requests that it be recognized as having the right to compensatory interest, pursuant to Article 43 of the LGT.

In accordance with the provision of Article 43(1) of the LGT, compensatory interest is due "when it is determined, in administrative appeal or judicial challenge, that there was an error attributable to the services as a result of which payment of the tax debt was made in an amount greater than that legally due." As follows from Article 24(5) of the RJAT, the right to said interest may be recognized in the arbitral proceedings.

  1. The right to compensatory interest referred to in the provision of the LGT presupposes that tax was paid in an amount greater than that due and that such derives from an error, of fact or of law, attributable to the services of the Tax Authority. In the present case, even though it is acknowledged that the tax paid by the Claimant is not due, it is not apparent that, at its origin, there is an error attributable to the Tax Authority. In making the ex officio assessment of the IUC, the Tax Authority merely complied with the provision of Article 3(1) of the CIUC and attributed the status of taxpayer of this tax to the persons in whose name the vehicles are registered.

Article 3(1) of the CIUC has the nature of a legal presumption; therefrom results, for the Tax Authority, the right to assess the tax and demand it from these persons, without the need to prove the facts that lead to it, as expressly provided for in Article 350(1) of the Civil Code.

  1. The Respondent in its response considers that, in the event the Claimant's claim is deemed well-founded, it should not be condemned to costs, because it did not give rise to the dispute.

Article 527 (General rule on costs) of the Code of Civil Procedure (CPC) provides as follows:

"1 — The judgment that decides the action or any of its incidents or appeals condemns in costs the party that has given cause to them or, in the absence of judgment of the action, the one who benefited from the proceedings.

2 — It is understood that the losing party gives cause to the costs of the proceedings, in the proportion in which it lost.

3 — In the case of condemnation by joint and several obligation, solidarity extends to costs."

The Arbitral Tribunal, in accordance with the foregoing, judged the Claimant's request well-founded and, therefore, in accordance with Article 527(1) and (2) of the CPC, applicable by virtue of subparagraph (e) of Article 29(1) of the RJAT, the responsibility for payment of the arbitration fee is unequivocally that of the Respondent.

V – DECISION

In accordance with the foregoing, it is decided:

a) To judge the request for arbitral ruling well-founded as regards the rebuttal of the presumption of subjective incidence of the IUC and consequently to annul the assessments of this tax, to which the collection documents attached to the request for arbitral ruling presented by the Claimant refer, and to order the restitution of the tax improperly collected;

b) To judge the request unfounded as regards the recognition of the right to compensatory interest in favor of the Claimant;

c) To condemn the Respondent to pay the costs of the present proceedings.

The value of the case is set at € 142.70 (one hundred and forty-two euros and seventy cents), in accordance with the provisions of Article 97-A(1), subparagraph (a), of the CPPT, applicable by virtue of subparagraphs (a) and (b) of Article 29(1) of the RJAT and Article 3(2) of the Regulation on Costs in Tax Arbitration Proceedings.

The arbitration fee is set at € 306.00 (three hundred and six euros), in accordance with Table I of the Regulation on Costs in Tax Arbitration Proceedings (RCPAT), to be paid in full by the Claimant, in accordance with Article 22(4) of the RJAT.

Frequently Asked Questions

Automatically Created

Who is liable for IUC payment on vehicles under a financial leasing agreement in Portugal?
Under Portuguese tax law, IUC liability on vehicles under financial leasing agreements is primarily determined by vehicle registry records. Article 3 of the IUC Code establishes that the person registered as the vehicle owner in the Motor Vehicle Registry Office (Conservatória do Registo Automóvel) is generally liable for IUC payment. In financial leasing contexts, this creates a critical issue: even when the lessee exercises the purchase option and acquires full ownership by paying the residual value, if the ownership transfer is not formally registered, the financial leasing company (lessor) remains the registered owner and can be assessed for IUC. The registration creates a legal presumption of ownership for tax purposes that can only be rebutted with sufficient evidence, though unilateral documents like invoices may have limited probative value against official registry data.
Can a financial leasing company challenge IUC tax assessments through CAAD tax arbitration?
Yes, financial leasing companies can challenge IUC tax assessments through CAAD (Centro de Arbitragem Administrativa) tax arbitration. As demonstrated in Process 227/2014-T, credit institutions engaged in financial leasing operations have legal standing to request arbitral tribunals under the RJAT (Legal Regime for Arbitration in Tax Matters - Decree-Law No. 10/2011). The process involves filing a request for constitution of an arbitral tribunal, appointment of an arbitrator (either chosen by parties or appointed by CAAD's Deontological Council), submission of a Response by the Tax Authority within 30 days, and optional hearings under Article 18 of RJAT. This arbitration mechanism provides financial institutions an efficient alternative to judicial courts for disputing IUC liquidations, particularly when contesting assessments based on registration presumptions that don't reflect the economic reality of completed lease-to-own transactions.
What is the subjective incidence rule for IUC on leased vehicles under Portuguese tax law?
The subjective incidence rule for IUC on leased vehicles under Portuguese tax law is governed by Article 3(1) of the IUC Code and centers on registered ownership. The rule establishes that the taxable person is the individual or entity appearing as the vehicle owner in the Motor Vehicle Registry Office records at the relevant tax date. In financial leasing arrangements, this creates a specific challenge: during the active lease period, the lessor (financial institution) typically remains the registered owner while the lessee has possession and use. When the lessee exercises the purchase option and completes the acquisition by paying the residual value, economic ownership transfers immediately, but tax liability remains with the registered owner until formal registration occurs. This registration presumption means financial leasing companies can be held liable for IUC even after vehicles are effectively sold, unless the purchasers complete the registry transfer. The burden falls on the party challenging the assessment to rebut this presumption with sufficient evidence proving they are no longer the actual owner at the relevant tax date.
How does the CAAD arbitration process work for disputing IUC vehicle tax liquidations?
The CAAD arbitration process for disputing IUC vehicle tax liquidations follows a structured procedure under the RJAT (Regime Jurídico da Arbitragem em Matéria Tributária). The taxpayer files a request for constitution of an arbitral tribunal identifying the contested assessments and legal grounds. CAAD's President accepts the request and notifies the Tax and Customs Authority. An arbitrator is appointed either by the parties' choice or by CAAD's Deontological Council if no preference is indicated. Once constituted, the tribunal notifies the Tax Authority to submit a Response within 30 days. Both parties can waive the optional hearing under Article 18 of RJAT and proceed directly to decision. The tribunal evaluates material competence, parties' standing and legitimacy, timeliness of submissions, and absence of invalidating defects before ruling on the merits. For IUC disputes involving multiple vehicles with identical factual and legal grounds, claims can be cumulated under Article 104 of CPPT and Article 3 of RJAT, providing efficiency in resolving similar assessments through a single arbitral proceeding.
Are lessees or lessors responsible for paying Imposto Único de Circulação on financed vehicles?
Responsibility for paying Imposto Único de Circulação (IUC) on financed vehicles in Portugal depends on registration status rather than economic ownership or possession. Under the subjective incidence rules of Article 3 of the IUC Code, the registered owner bears primary liability. In typical financial leasing arrangements, the lessor (financial institution) maintains registered ownership throughout the lease term, making them technically liable for IUC, though lease contracts often impose this obligation contractually on the lessee. The critical moment occurs when the lessee exercises the purchase option: although economic ownership transfers upon payment of the residual value, tax liability remains with the lessor until the purchaser completes the formal registration transfer at the Motor Vehicle Registry Office (Conservatória do Registo Automóvel). This creates a gap where financial institutions can be assessed for IUC on vehicles they no longer economically own, with limited ability to rebut the registration presumption through unilateral documents like sales invoices. Therefore, while lessees often assume contractual responsibility for IUC payments during the lease, lessors remain exposed to tax assessments based on their registered owner status until registry updates are completed.
