Process: 53/2017-T

Tax Type: IUC

Source: Original CAAD Decision

Summary

CAAD arbitral decision Process 53/2017-T addresses the critical question of IUC subjective incidence when vehicles under financial leasing contracts are transferred to lessees who exercised purchase options. A leasing company (A... S.A.) challenged IUC assessments totaling €269.06 for tax years 2013-2014, arguing it was not the taxable person since the vehicles had already been sold to lessees through purchase option exercises, despite remaining registered in the company's name. The Tax Authority assessed IUC based on vehicle registration records, dismissing the company's gracious complaints and hierarchical appeals. The core legal dispute centers on whether IUC subjective incidence follows formal vehicle registration or actual ownership transfer upon completion of financial leasing contracts. This case has significant implications for leasing companies and financial institutions operating in the automotive sector, particularly regarding the timing gap between actual vehicle transfers to lessees and formal registration updates. The tribunal examined whether payment obligations persist when registration records lag behind contractual ownership transfers, a common scenario in financial leasing operations where lessees acquire vehicles by paying residual values but administrative registration transfers experience delays.

Arbitral Decision

I. Report

  1. A... S.A., collective person no. ..., with registered office at Rua..., ..., ...-... Lisbon, requested the constitution of an arbitral tribunal in tax matters, raising a request for an arbitral pronouncement against the acts of dismissal of hierarchical appeals filed against the dismissal of gracious complaints and, consequently, against the acts of assessment of Single Vehicle Circulation Tax (IUC) relating to the years 2013 and 2014 and to motor vehicles identified by their respective registration number in a list and documents annexed to the request (Annex A), whose annulment it requests. As a consequence of said annulment, it requests the condemnation of the Tax Authority to the reimbursement of the amount it considers unduly paid, in the total amount of € 269.06, being € 257.36 of tax and € 11.70 of compensatory interest, plus the corresponding indemnificatory interest calculated according to legal terms.

  2. As grounds for the request, presented on 16-01-2017, the Applicant alleges, in summary, that having timely presented gracious complaints against the IUC assessments in question, these were dismissed, with the same fate befalling the hierarchical appeals timely filed against those decisions.

  3. As grounds for said complaints and subsequent hierarchical appeals against the decisions thereon rendered, the Applicant invokes the fact that it is not the passive subject of the IUC obligation relating to the taxation periods and vehicles to which the disputed assessments pertain.

  4. According to the Applicant's allegation, the said vehicles, although registered in its name as of the date to which the tax events to which those assessments pertain are referred, had already been transferred to third parties, following the exercise of a purchase option by the respective lessees under financial leasing contracts.

  5. In response to what was requested, the Tax and Customs Authority (AT) pronounced itself in the sense of the inadmissibility of the present request for an arbitral pronouncement, maintaining the tax acts contested in the legal order and, accordingly, for the discharge of the Respondent.

  6. The request for constitution of the arbitral tribunal was accepted by the President of CAAD and automatically notified to the Tax and Customs Authority on 27-01-2017.

  7. Pursuant to the provisions of subsection a) of article 6, paragraph 2, and subsection b) of article 11, paragraph 1, of Decree-Law no. 10/2011, of 20/01, as amended by article 228 of Law no. 66-B/2012, of 31/12, the Deontological Council appointed the undersigned as arbitrator of the sole arbitral tribunal, who communicated acceptance of the appointment within the applicable time period, and notified the parties of such appointment on 13-03-2017.

  8. Duly notified of such appointment, the parties did not manifest any will to challenge the arbitrator's appointment pursuant to the combined provisions of article 11, paragraph 1, subsections a) and b), of the RJAT and articles 6 and 7 of the Deontological Code.

  9. Thus, in accordance with the provision in subsection c) of article 11, paragraph 1, of the RJAT, as amended by article 228 of Law no. 66-B/2012, of 31/12, the sole arbitral tribunal was constituted on 28-03-2017.

  10. Being duly constituted, the arbitral tribunal is materially competent, in view of the provisions in articles 2, paragraph 1, subsection a), of the RJAT.

  11. The parties have legal personality and capacity and have standing (articles 4 and 10, paragraph 2, of the RJAT, and article 1 of Ordinance no. 112-A/2011, of 22/03).

  12. No nullities occur and no prior questions or exceptions have been raised, so nothing prevents judgment on the merits, the present proceedings thus being in conditions for the final decision to be rendered therein.

  13. In view of the knowledge derived from the procedural documents submitted by the parties, in particular from the administrative file, which is deemed sufficient for the decision, the Tribunal decided to dispense with the hearing alluded to in article 18 of the RJAT.

  14. As no doubts arise regarding the determination of the duly proven facts in view of documentary evidence, and considering that exclusively a matter of law is at issue, the Tribunal decided to dispense with witness testimony.

II. Facts

  1. Of relevance for the appreciation of the questions raised, the following factual elements are highlighted, which, based on the documentary evidence attached to the file, are considered proven:

15.1. The Applicant is a credit institution which, within the scope of its corporate purpose, practices all operations and provides all services permitted to banks.

15.2. Among its areas of activity, the financing of the automotive sector assumes special relevance, with a substantial part of its activity being reduced to the execution of financial leasing contracts intended for the acquisition, by companies and individuals, of motor vehicles.

15.3. To that effect, the present Applicant acquires the vehicles indicated by customers from their respective suppliers, proceeding subsequently to their delivery to the lessees.

15.4. During the period stipulated in the contract, these lessees maintain temporary use of the vehicle — which remains the property of the Applicant — through remuneration to be delivered to the Applicant in the form of leasing payments; being able to acquire the vehicle at the end of the contract by payment of a residual value.

15.5. The motor vehicles to which the disputed assessments pertain, identified in a list annexed to the request for arbitral pronouncement (Annex A), were delivered to their respective lessees under financial leasing contracts.

15.6. All lessees acquired, at the end of their respective contract, the motor vehicle to which it pertained, by payment of the corresponding residual value, as evidenced by their respective sales invoices (Docs. no. 9 to 12).

15.7. Concerning the motor vehicles identified in the said Annex A by their respective registration number, and the taxation periods of 2013 and 2014, the Tax Authority made official assessments of IUC, plus compensatory interest, in the total amount of € 269.06.

15.8. Notified of said assessments, the present Applicant made voluntary payment of the tax (Cf. Docs. 1 to 4).

15.9. However, it reacted against said assessment acts through gracious complaints in which, in essence, it alleges that it is not the passive subject of the tax obligation since, on the date of occurrence of the respective tax events to which those assessments pertain, the vehicles to which they relate had already been transferred to the respective lessees by exercise by them of a purchase option under financial leasing contracts.

15.10. The complaints presented, as appears from the elements that form part of the present proceedings, were subject to express dismissal.

15.11. Hierarchical appeals were filed against said decisions, also dismissed in their entirety.

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

III. Cumulation of Claims

  1. The present request for arbitral pronouncement relates to various IUC assessments. However, given the identity of the tax facts, the tribunal competent for the decision, and the grounds of fact and law invoked, the tribunal considers that nothing prevents, in view of the provisions in articles 3 of the RJAT and 104 of the CPPT, the cumulation of claims.

IV. Legal Matter

  1. In the request for arbitral pronouncement, the Applicant submits to the appreciation of this tribunal the legality of acts of express dismissal of hierarchical appeals filed against decisions of dismissal of gracious complaints and, consequently, the legality of the acts of assessment of IUC relating to the periods of 2013 and 2014 and to the vehicles it identifies in a list annexed to the request (cfr. Annex A), invoking the circumstance that, as of the date to which the tax facts giving rise to them are referred, these had already been transferred to their respective lessees following the exercise, by them, of a purchase option under financial leasing contracts, and, consequently, does not assume the status of passive subject of the tax assessed against it.

  2. The question is thus whether the Applicant should or should not be considered the passive subject of IUC as to the vehicles and periods to which the tax pertains, duly identified in an annex to the request, because, as of the date of the tax's due date, they had already been transferred to third parties.

  3. Regarding this matter, article 3 of the CIUC provides, in its paragraphs 1 and 2, in the wording in force at the date of the facts under analysis, that:

"1 - The passive subjects of the tax are the owners of the vehicles, being considered as such the natural or legal persons, of public or private law, in whose name they are registered.

  1. Financial lessees, acquirers with reservation of ownership, as well as other holders of purchase option rights by force of a leasing contract are equated to owners."

  2. According to the understanding of the Respondent, said rule does not comprise any legal presumption, considering that "The tax legislator, in establishing in article 3, paragraph 1, who are the passive subjects of the IUC, established express and intentionally that these are the owners (or in the situations provided for in paragraph 2 the persons stated therein), being considered as such the persons in whose name they are registered."

  3. For its part, the Applicant maintains that said rule enshrines a legal presumption, rebuttable according to general terms and, in particular, by force of the provisions in article 73 of the General Tax Law according to which the presumptions of tax incidence always admit proof to the contrary.

  4. This matter has been the subject of numerous decisions in the context of the arbitral tribunals operating at CAAD, generally in the sense of the admissibility of the respective requests, on the ground that the rule in question, in the wording in force at the date of the facts to which the present request pertains, contains a legal presumption that admits proof to the contrary.[i]

  5. Adhering, thus, to the position referred to above, the reproduction of the respective grounds is dispensed with as unnecessary and tedious, since in the present proceedings nothing new is brought forward on this matter.

On the Rebuttal of the Presumption

  1. Presumptions of tax incidence may be rebutted through the contradictory procedure provided for in article 64 of the CPPT or, alternatively, through a gracious complaint or judicial challenge of the tax acts based thereon.

  2. In the present case, the Applicant did not use that specific procedure, so the present request for an arbitral decision, following the dismissal of a request for official revision and subsequent hierarchical appeal, is an appropriate means to rebut the presumption of subjective tax 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 scope of the material competence of this arbitral tribunal (articles 2 and 4 of the RJAT).

  3. Appearing as the Applicant in the motor vehicle register as owner of the vehicles identified in the request during the taxation periods to which the questioned assessments pertain, and alleging that these had already been transferred to the lessees by exercise by them of a purchase option under financial leasing contracts, it remains to evaluate the evidence presented, in order to determine whether it is sufficient to rebut the presumption established in paragraph 1 of article 3 of the same Code.

  4. To rebut the presumption derived from the motor vehicle register, the Applicant offers, as means of proof, the invoicing issued with reference to the transfer of the vehicles to which the questioned assessments pertain (Docs. no. 9 to 12).

  5. Pronouncing itself on the documentary evidence presented, the Respondent alleges that "by force of the provisions in article 3, paragraphs 1 and 2 of the CIUC and article 6 of the same Code, the Applicant, in its capacity as owner registered in the Motor Vehicle Registry, is the passive subject of the IUC." Therefore, according to its understanding, "all the reasoning advocated by the Applicant is riddled with error, and it is not possible to rebut the legal presumption established."

  6. However, the Respondent adds that "even if this were not so – which is only admitted purely as an academic hypothesis – and accepting that rebuttal of the presumption is admissible in light of the jurisprudence already established at this arbitration centre, it would still be necessary to evaluate the documents submitted by the Applicant and their probative value with a view to such rebuttal."

  7. Contesting documents no. 9 to 12 submitted by the Applicant, the Respondent maintains that "The invoices are not apt to prove the execution of a synallagmatic contract such as a purchase and sale, as such documents do not reveal by themselves an essential and unequivocal declaration of intent (i.e., acceptance) by the alleged acquirers."

  8. In this sense, the Respondent argues that "

  • The rules of the motor vehicle register have not yet reached the point where an invoice unilaterally issued by the Applicant can replace the Motor Vehicle Registration Form, a document approved by official model;

  • An unequivocal declaration of intent by the alleged acquirer could be evidenced by the attachment of a copy of said official form for motor vehicle property registration, as it is a document signed by the intervening parties;

  • However, the Applicant did not attach a copy of said official form for motor vehicle property registration when it could and should have done so, that is, in the request for arbitral pronouncement, finding itself precluded from the possibility of doing so at a later time..."

  1. Beyond the substantive position it expresses regarding the insufficiency of commercial invoices to exclude the presumption of IUC incidence, the Respondent questions the probative value of the documents presented by the Applicant, in the following terms:

"Moreover, concerning the value or probative force of the invoices embodied in Documents 9 to 12 attached to the application, serious doubts arise regarding their veracity, such are the discrepancies they present, and one can speculate that their attachment constitutes a hasty attempt to demonstrate a non-existent reality, to wit:

In the first place, the "invoices" allegedly referring to the sales of vehicles with registration numbers no. ...-...-... and no....-.....do not even possess the legal requirements to be considered invoices.

Indeed, those documents DO NOT even contain:

  • The name or designation of the alleged seller;

  • The tax identification number of the alleged seller; and

  • The registered office of the alleged seller.

It is emphasized: there is not even a minimal reference to the Applicant and/or to any identifying element thereof!

In simpler terms: it is not known who allegedly sold the vehicle.

In the second place, and as a direct consequence of what has just been set out, one thing is now certain: given the absence of the legal requirements for invoices (cfr. article 36/5 of the Value Added Tax Code), it is necessary to conclude that the "invoices" just listed CAN NEVER benefit from the presumption of truthfulness to which article 75 of the LGT refers.

On the contrary, the noted omissions and inconsistencies between the alleged facts and the document in question are of such an order that serious doubts arise regarding its veracity, and one can speculate that its attachment constitutes a hasty attempt to demonstrate a non-existent reality, in light of what has been shown above."

  1. As the Respondent's position on the evidence produced clearly shows, this would generally be insufficient to exclude the tax incidence defined on the basis of ownership, as it appears from the register, which, in consistency with the substantive position it has assumed, would only be excluded based on timely updating of the register itself.

  2. Not being this the tribunal's understanding, it is important to evaluate the evidence produced by the Applicant in order to determine whether it is sufficient to rebut the presumption derived from the motor vehicle register which, on the plane of subjective incidence, is adopted for purposes of the IUC.

  3. To that end, it is important to bear in mind that, in the situation under analysis, contracts of purchase and sale are at issue which, relating to movable things and not being subject to any special formalism (Civil Code, article 219), effect the corresponding transfer of real rights (Civil Code, article 408, paragraph 1).

  4. Involving contracts that entail the transmission of ownership of movable property, by payment of a price, these have, as essential effects, among others, that of delivering the thing (Civil Code, articles 874 and 879).

  5. However, since a contract of purchase and sale is at issue that has a motor vehicle as its object, in which registration is mandatory, its punctual performance presupposes the issue of a declaration of sale necessary for the inscription in the register of the corresponding acquisition in favor of the buyer, as has been understood by the jurisprudence of the higher courts.[ii] Such a declaration, relevant for purposes of registration, may constitute proof of the transaction, but is not the only or exclusive means of proof of the transaction.

  6. For registration purposes, no special formalism is required either, a request submitted to the competent entity being sufficient, signed by the buyer and confirmed by the seller who, through a declaration of sale, confirms that ownership of the vehicle was acquired by that party through a verbal contract of purchase and sale (see Motor Vehicle Register Regulation, article 25, paragraph 1, subsection a).

  7. Notwithstanding these being the rules flowing from the provisions of civil law, relating to the informalism of the transmission of movable things and, where applicable, their registration, it cannot be overlooked that, in the situation under analysis, we are dealing with commercial transactions, carried out by a business entity within the scope of the activity that constitutes its corporate purpose.

  8. Within that scope, the enterprise is bound to comply with specific accounting and tax norms, in which invoicing assumes special relevance.

  9. Firstly, by force of tax norms, the entity transferring the goods is obliged to issue an invoice for each transfer of goods, regardless of the status of the respective acquirer (CIVA, article 29, paragraph 1, subsection b).

  10. Also in accordance with the provisions of tax norms, the invoice must comply with a certain form, detailed regulated in articles 36 of the VAT Code and article 5 of Decree-Law no. 198/90, of 19/06.

  11. It is based on this document issued by the supplier of goods that the acquirer, when an economic operator, will deduct the VAT to which they are entitled (CIVA, article 19, paragraph 2) and record the expense of the operation (CIRC, articles 23, paragraph 6 and 123, paragraph 2).

  12. For its part, it is also based on the invoicing issued that the supplier of goods should record the respective income, as follows from the provisions in subsection b) of paragraph 2 of article 123 of the CIRC.

  13. Provided they are issued in the legal form and constitute supporting elements of accounting entries in accounting organized in accordance with commercial and tax legislation, the data contained therein are covered by the presumption of truthfulness referred to in article 75, paragraph 1, of the LGT.

  14. Indeed, said presumption covers not only the books and accounting records, but also their respective supporting documents, as is, moreover, a settled understanding of the tax authority itself [iii] and the established jurisprudence of the higher courts [iv].

  15. The presumption of truthfulness of commercial invoices issued in accordance with legal terms may, however, be set aside whenever the operations to which they refer do not correspond to reality, it being sufficient for this that the Tax Authority gathers and demonstrates well-founded indications of that fact (LGT, article 75, paragraph 2, subsection a).[v]

  16. Considering, thus, the relevance attributed by tax legislation to invoices issued, in accordance with legal terms, by commercial enterprises within the scope of their business activity, and the presumption of truthfulness of the operations evidenced thereby, it cannot fail to be considered that these constitute, by themselves, sufficient proof of the transfers invoked by the Applicant.

  17. However, as the Respondent correctly points out, some of the copies of invoices presented by the Applicant, as is the case with those intended to prove the transfer of vehicles with registration numbers ...-...-... and ...-...-, do not meet the formal requirements demanded by tax law. Indeed, they do not contain the identification — name and tax identification number — of the transferor.

  18. Not being met the formal requirements demanded, the presumption derived from the motor vehicle register cannot be considered rebutted with reference to the vehicles referred to, to which the assessments numbers ... and ... pertain.

  19. Regarding the remaining invoices, issued in the legal form, these are considered to constitute sufficient proof of the transfer of the right of ownership of the vehicles with registration numbers ...-...-. and ...-...-... on a date prior to that of the due date of the tax to which the assessments numbers ... and... pertain, relating to the taxation period of 2013.

  20. In these terms, the presumption of ownership derived from the motor vehicle register adopted in paragraph 1 of article 3 of the CIUC is considered rebutted, concerning the vehicles and periods to which the assessments referred to in the previous point pertain.

Request for Indemnificatory Interest

  1. Along with the annulment of the assessments, and consequent reimbursement of the amounts unduly paid, the applicant further requests that it be recognized as having the right to indemnificatory interest, under article 43 of the LGT.

  2. Indeed, pursuant to the provision in paragraph 1 of said article, indemnificatory interest is due "when it is determined, in a gracious complaint or judicial challenge, that there was an error attributable to the services from which resulted payment of the tax debt in an amount greater than legally due." In addition to the means referred to in the provision that is transcribed, we understand that, as follows from paragraph 5 of article 24 of the RJAT, the right to the mentioned interest can be recognized in the arbitration proceedings and thus the request is known.

  3. The right to indemnificatory interest referred to in the above-mentioned provision of the LGT presupposes that tax was paid in an amount greater than due and that this derives from an error, of fact or law, attributable to the services of the AT.

  4. In the present case, even recognizing that part of the tax paid by the Applicant is not due, as it is not the passive subject of the tax obligation, determining, consequently, its respective reimbursement, it does not appear that, at its origin, there is the error attributable to the services that determines such a right in favor of the taxpayer.

  5. Indeed, by promoting the official assessment of the IUC considering the Applicant as the passive subject of this tax, the AT merely limited itself to complying with the provision in paragraph 1 of article 3 of the CIUC, which, as mentioned above at length, attributes such status to the persons in whose name the vehicles are registered.

  6. On the other hand, also as already concluded, said provision has the nature of a legal presumption, from which it follows, for the AT, the right to assess the tax and exact it from such persons, without need to prove the facts leading thereto, as expressly provided in paragraph 1 of article 350 of the Civil Code.

  7. However, concerning the assessments that are the object of the present request for arbitral pronouncement, it is important to know whether the act of dismissal of the claim of the present Applicant, formulated in the gracious complaint timely filed, constitutes, or does not constitute, an error attributable to the Tax Authority for purposes of the exigibility of indemnificatory interest, under article 43, paragraph 1, of the LGT.

  8. On this matter, the orientation stemming from the jurisprudence of the Supreme Administrative Court is taken into account, which goes in the direction of recognizing that a decision of the Tax Authority that dismisses a request for annulment of admittedly illegal assessment and consequent restitution of unduly collected tax constitutes an error attributable to the services.

  9. According to the mentioned jurisprudence – expressed in a learned decision of 28-10-2009, in proc. no. 601/09 – indemnificatory interest is due from the date of dismissal of the complaint until the date of processing of the respective credit note, in accordance with article 61 of the CPPT.

  10. Adopting the orientation referred to, the right of the Applicant to indemnificatory interest is recognized with reference to the assessments to which the file pertains and which, by the present decision, are subject to annulment.

V - Decision

In these terms, and with the grounds set out, the Arbitral Tribunal decides:

a) To dismiss the request for arbitral pronouncement insofar as it concerns the rebuttal of the presumption of subjective tax incidence of IUC, concerning the periods of 2013 and 2014 for the vehicles with registration numbers ...-...-... and ...-...-..., maintaining, consequently, their respective assessments;

b) To uphold the request for arbitral pronouncement insofar as it concerns the rebuttal of the presumption of subjective tax incidence of the IUC, concerning the vehicles with registration numbers ...-...-. and ...-...-..., to which the IUC assessments of the period 2013 pertain, determining their annulment and consequent reimbursement of the amounts unduly paid.

c) To uphold the request for recognition of the right to indemnificatory interest, but only with reference to the assessments whose annulment is determined in the present decision and calculated from the date of dismissal of the corresponding gracious complaints.

Case Value

The case value is fixed at € 269.06, pursuant to article 97-A, paragraph 1, subsection a) of the CPPT, applicable by reference from article 29, paragraph 1, subsections a) and b), of the RJAT and article 3, paragraph 2, of the Regulation of Costs in Tax Arbitration Proceedings.

Costs

Under article 22, paragraph 4, of the RJAT, and in accordance with Table I annexed to the Regulation of Costs in Tax Arbitration Proceedings, the amount of the costs is fixed at € 306.00, owed by the Respondent and the Applicant, in the proportion of their respective success: € 149.59 and € 156.41, respectively.

Frequently Asked Questions

Automatically Created

Who is the taxable person for IUC when a vehicle has been sold after a financial leasing contract ends?
Under Portuguese tax law, IUC subjective incidence is primarily determined by vehicle registration records. When a financial leasing contract ends and the lessee exercises the purchase option, the taxable person transitions from the leasing company to the new owner. However, until registration is formally transferred, the person listed as the registered owner on the tax event date (typically January 1st) remains liable. This creates potential disputes when actual ownership transfers precede registration updates, as occurred in Process 53/2017-T where the leasing company argued it should not be taxed for vehicles already sold to lessees.
Can a former registered owner challenge IUC assessments if the vehicle was already transferred to the lessee?
Yes, a former registered owner can challenge IUC assessments through administrative complaints (reclamação graciosa) followed by hierarchical appeals (recurso hierárquico), and ultimately through CAAD arbitration as demonstrated in this case. The challenge must prove that despite registration records showing the former owner, actual ownership had transferred to another party as of the tax event date. The success of such challenges depends on demonstrating that the legal requirements for ownership transfer were completed, including execution of purchase options under financial leasing contracts and payment of residual values, even if formal registration updates were pending.
What is the subjective incidence rule for IUC on vehicles still registered under a leasing company?
IUC subjective incidence follows Article 3 of the IUC Code, which establishes that the taxable person is whoever appears as the vehicle owner in the registration records on the date of the tax event. For leasing companies, this means they remain liable for IUC until registration is transferred to the lessee, even after purchase options are exercised. This creates a temporal gap issue where economic ownership has transferred but legal registration-based tax liability persists. Process 53/2017-T exemplifies this conflict, with the leasing company arguing that actual transfer through executed purchase options should determine tax liability rather than registration formalities.
How does the CAAD arbitral tribunal handle IUC disputes involving vehicle registration and actual ownership?
CAAD arbitral tribunals examine IUC disputes by analyzing both formal registration records and the substantive reality of ownership transfers. The tribunal evaluates evidence including financial leasing contracts, sales invoices proving residual value payments, purchase option exercises, and the timing of actual vehicle transfers versus registration updates. In Process 53/2017-T, the tribunal constituted a sole arbitrator who reviewed the administrative file, including evidence of purchase option exercises and sales invoices. The tribunal's role includes determining whether subjective incidence should follow strict registration formalism or recognize economic substance when ownership has genuinely transferred despite administrative delays.
What remedies are available to taxpayers who paid IUC on vehicles they no longer owned?
Taxpayers who paid IUC on vehicles they no longer owned have several remedies: (1) file gracious complaints (reclamação graciosa) within the statutory deadline, arguing lack of subjective incidence; (2) if dismissed, pursue hierarchical appeals (recurso hierárquico); (3) request arbitration through CAAD as the applicant did in Process 53/2017-T, seeking annulment of assessments and reimbursement of amounts paid plus compensatory and indemnificatory interest. The claim must demonstrate that on the tax event date, despite registration records, actual ownership had transferred through legally binding mechanisms such as executed purchase options in financial leasing contracts. Success requires comprehensive documentary evidence including contracts, payment records, and transfer documentation.
