Process: 714/2015-T

Date: September 22, 2016

Tax Type: IUC

Source: Original CAAD Decision

Summary

This arbitration decision addresses the critical question of IUC (Unique Vehicle Circulation Tax) liability in the first year of vehicle registration in Portugal. The claimant, a vehicle importing company, challenged two 2011 IUC assessments, arguing it should not be liable as the initial registrant when vehicles were sold and re-registered to purchasers within the legal 60-day registration period. The core legal dispute centers on interpreting Article 3(1) of the CIUC, which establishes that taxable persons are vehicle owners as registered in the Vehicle Registry. The claimant contended that since the vehicles were sold in July and December 2011 and properly re-registered to buyers within the statutory timeframe, the purchasers—not the dealer—became the liable parties. Supporting this position, the claimant invoked Article 17(1) requiring self-assessment within 30 days after the legal registration period, and Article 18(1)(a) which by contrario interpretation only imposes liability on the initial registrant when re-registration fails to occur within the legal period. The claimant further argued that registration creates only a rebuttable presumption of ownership, which sales invoices effectively rebutted. The Tax Authority countered that the importer, as the first registered owner required by law to register vehicles upon importation, automatically becomes the IUC taxable person for the initial taxation period under Articles 3 and 6 of the CIUC. The Authority argued that accepting the claimant's interpretation would create taxation gaps when registration occurs in one year but transfer in the next, and that sales invoices alone cannot override the formal registration record for tax purposes. The Authority also raised a procedural objection regarding the 90-day time limit under Article 10 of the RJAT. This case highlights the tension between formal registration requirements for importers and the principle that IUC should burden actual vehicle users.

ARBITRAL DECISION

Claimant: A…, Unipessoal Lda.

Respondent: AT - Tax and Customs Authority

I - REPORT

Request

A…, Unipessoal Lda, legal entity no. …, with registered office at …, Avenue …, plot …, …, …, in Lisbon, hereinafter referred to as the Claimant, filed on 30-11-2015, pursuant to the provisions of paragraph a) of article 1, paragraph 1, and article 10 of Decree-Law no. 10/2011, of 20 January, which approves the Legal Framework for Arbitration in Tax Matters (RJAT), a request for arbitral pronouncement, in which the AT - Tax and Customs Authority is the Respondent, with a view to:

  • Declaration of illegality of two assessments of the Unique Vehicle Circulation Tax relating to the year 2011;

  • Condemnation of the Respondent to reimburse the amounts incorrectly assessed and paid in the meantime, plus the respective compensatory interest.

The Claimant alleges, essentially, the following:

  • The assessments in question are affected by illegality due to errors in the legal and factual premises relating to the tax event;

  • In accordance with article 3, paragraph 1, of the Unique Vehicle Circulation Tax Code (CIUC), the passive subject of the tax is the owner of the vehicle, the same provision stating that the owner of the vehicle is considered to be the person registered as such in the Vehicle Registry;

  • In the cases at hand, the vehicles, after having been initially registered in the name of the Claimant, as the law requires, were sold – on 13 July 2011 and on 9 December 2011 - and registered in the names of the purchasers, within the legal period of 60 days following the assignment of the registration numbers;

  • Pursuant to article 17, paragraph 1, of the CIUC, in the year of the registration of the vehicle in national territory, the tax is assessed by the passive subject of the tax within 30 days following the end of the legally required period for the registration thereof, since what is relevant for the purposes of the incidence of the tax is who acquires the vehicle for their own use and circulation.

  • Being the passive subject of the tax the holder of the registration and ownership, and having such registration been effected by the new owners within the legal period therefore, it is clear that the passive subject of the tax in question is not the Claimant but the purchasers and holders of the registration;

  • This understanding is derived from the contrario interpretation of article 18, paragraph 1, letter a) of the CIUC, according to which "in the absence of registration of ownership of the vehicle effected within the legal period, the tax due in the year of the registration of the vehicle is assessed and collected from the passive subject of the tax on vehicles on the basis of the customs declaration of the vehicle, or on the basis of the supplementary declaration of vehicles on which the assessment of such tax is based, even if not due;

  • By virtue of several legal provisions, among which article 4, paragraph 1, of Decree-Law 178-A/2005, of 28.10, the Claimant is obliged, in order to obtain the registration certificate of the vehicles imported by it, to proceed with their registration in its name;

  • However, taxation under the Unique Vehicle Circulation Tax (IUC) is intended to burden the entities that use the vehicle, whereby the Claimant, as the first holder of the registration, by virtue of legal imperatives, is not placed in the position of passive subject;

  • The registration constitutes a presumption that the right exists and belongs to the registered holder, in the precise terms in which the registration defines it;

  • Such presumption is rebuttable, as has been considered by the jurisprudence of the superior courts;

  • Having presented invoices through which it proved to have proceeded with the sale of the vehicles, the Claimant rebutted the presumption of the registration;

Response of the Respondent

In response to the request for pronouncement presented by the Claimant, the Respondent AT - Tax and Customs Authority alleges:

A) By way of exception:

  • The request is time-barred, since it was presented beyond the period of 90 days counted from the end of the period for voluntary payment, as provided for in article 10 of the RJAT and, although a petition for administrative review was filed, the request was not directed against the petition for administrative review.

B) By way of substantive defence:

  • Under article 17 of the CIUC, the introduction into consumption and assessment of tax on vehicles that do not have national registration is titled by the issuance of a Customs Declaration of Vehicles ("DAV");

  • Under article 117, paragraph 4, of the Road Code, the registration is requested from the IMTT by the entity that proceeds with the admission or introduction into consumption of the vehicle;

  • Article 24, paragraph 1, of the Motor Vehicle Registration Regulation (Decree-Law 55/75 of 12 February – hereinafter "RRA") provides that "The initial registration of ownership of vehicles imported, admitted, assembled, constructed, or reconstructed in Portugal is based on the respective request and proof of compliance with the tax obligations relating to the vehicle;"

  • Under the IUC, article 3, paragraph 1, of the CIUC establishes that "the passive subjects of the tax are the owners of the vehicles, considered as such the natural or legal persons, of public or private law, in whose names such vehicles are registered;"

  • With regard to the tax event and the exigibility of the tax, article 6 of the CIUC determines that the tax event is constituted by the ownership of the vehicle, as evidenced by the registration or registration in national territory;

  • As to the period of assessment, article 17, paragraph 1, provides that, in the year of the registration of the vehicle in national territory, the tax is assessed by the passive subject of the tax within 30 days following the end of the legally required period for the registration thereof;

  • From the articulation between the scope of the subjective incidence of the IUC and the constitutive fact of the corresponding tax obligation, it follows unequivocally from article 6 of the CIUC the legal situations that generate the birth of the tax obligation, namely, the registration in national territory;

  • In turn, paragraph 3 of article 6 provides that the tax is considered exigible on the first day of the taxation period referred to in paragraph 2 of article 4, from which it follows that the moment from which the tax obligation is constituted presents a direct relationship with the issuance of the registration certificate;

  • From the set of applicable provisions it results that the issuance of the registration certificate automatically originates the registration of the ownership of the vehicle, under article 24 of the Motor Vehicle Registration Regulation, in the name of the entity that proceeded with the importation and request for registration of the vehicle, namely, the Claimant;

  • Thus, the importer appears in the registry as the first owner of the vehicle and in that sense is, in accordance with what is established in articles 3 and 6 of the CIUC, the passive subject of the tax;

  • If the interpretation proposed by the Claimant were accepted, the formula would be found to exclude taxation for IUC in the case where the registration certificate was issued in a given year and the vehicle registered and only the subject of registration in the name of another owner in the following year;

  • Furthermore, article 3 contains no legal presumption;

  • The presumption of ownership of the vehicles in question derives directly from the motor vehicle registration regime, whereby the rebuttal of the presumption shall have to be directed to the motor vehicle registration itself, by the means provided for in the respective regulation;

  • The invoices that the Claimant presents to prove the conclusion of contracts of sale and purchase are not documents fit to prove the existence of a synallagmatic contract;

  • Given that these invoices mention a reservation of ownership clause until full payment, the Claimant does not prove payment;

  • The documents presented by the Claimant do not make it possible to establish the succession of transactions concerning the sales effected by the Claimant to the concessionaires;

  • The documents presented either embody mere entries or internal documents, with insufficient value to deny the validity of the facts – the ownership of the vehicles – on which there exists a legal presumption;

  • The exclusion of the subjective incidence of the IUC proposed by the Claimant contradicts the principle of legality and typicality established in article 8 of the LGT and article 103 of the CRP, since such understanding is not based on law;

  • The Claimant's understanding also conflicts with the principle of contributory capacity established in article 104 of the CRP and article 4 of the LGT, in attempting to exclude the subjective incidence of the tax;

Subsequent procedural steps

3.1. Request to respond to the substantive defence of exceptional nature raised by the Respondent

By order of the Court of 10 May 2016, the Claimant was notified of the grant of a period to exercise the right to be heard in relation to the questions of exceptional nature raised by the Respondent in its defence.

On 23 May 2016, the Claimant filed a request following the order of the Court of 10 May 2016, in which it responded to several questions raised in the defence of the Respondent.

In that request, the Claimant alleged the following:

  • Although the Claimant initially appeared, by legal imperative, as the owner of the vehicles in question, they were disposed of even before the issuance of the DAV, being therefore only the importer and not the actual owner or user;

  • In accordance with the Unique Vehicle Circulation Tax Code, the passive subject is the owner of the vehicle as it appears in the motor vehicle registry. However, this rule of incidence is based on a rebuttable presumption;

  • The registry also only presumes the ownership of the vehicle;

  • On the date when the tax became exigible, the A… was not the owner of the vehicles, whereby it was not the passive subject of the tax;

  • In accordance with article 17, paragraph 1, of the CIUC, in the year of the registration in national territory, the tax is assessed by the passive subject of the tax within 30 days following the time legally required for the registration thereof. Now in the present case, the vehicles were registered within the legal period, whereby the Claimant is not the actual owner thereof;

  • The Claimant presents the documents that prove that contracts for the sale of the vehicles were concluded and the respective price received;

  • The invoices presented enjoy a presumption of truthfulness under article 75 of the LGT, the AT failing to demonstrate the lack of correspondence between their contents and reality;

  • Such invoices are considered sufficient evidence within the scope of the special procedure for the registration of ownership of motor vehicles regulated in Decree-Law 177/2014, of 15 December;

As to the exception of time-barring of the request:

  • On 14 October a petition for administrative review was presented against the assessments in question, such petition being timely;

  • In accordance with the provisions of article 2, letter a) of Regulation 112-A/2011, of 22.3, the services of the Ministry of Finance and Public Administration are bound by the decisions of the CAAD, with the exception of the following: "a) claims relating to the declaration of illegality of self-assessment acts, withholding at source and payment on account that have not been preceded by recourse to the administrative path under the terms of articles 131 to 133 of the Code of Procedure and Tax Process;

  • Given this provision, the Claimant chose to present a petition for administrative review with two purposes: first, to obtain from the Administration itself the annulment of the illegal self-assessment; second, and in the event of not obtaining the annulment from the Administration, to be able, through an arbitral decision, to bind it to its contents;

  • Now, since recourse to such means of administrative appeal was imposed on the Claimant by legal imperative, in order to obtain the binding of the Respondent to the arbitral decision to be given, naturally the period of appeal provided for in article 10 of the RJAT shall have to be counted from the date of the rejection decision of the petition for administrative review;

  • Furthermore, the petition for administrative review should not be simultaneous with the mechanism of appeal since it could determine the existence of two contradictory decisions on the same question, hindering the expeditious resolution of the questions raised;

  • It is not true that the Claimant makes no reference, in its request, to the procedure of the petition for administrative review;

  • The Claimant petitions that it be "declared illegal the attribution of the IUC for the year 2011 and with reference to the vehicles with the registrations …-… -… and …-… -…;

  • The AT did not understand that, notwithstanding not having been written expressly by the now Claimant in the request that "be declared illegal the decision of rejection of the petition for administrative review", the request for declaration of illegality formulated is nothing more than the request for declaration of illegality of the administrative act emanating from the Tax Administration of rejection of the petition for administrative review;

  • After pronouncing unequivocally on the contents of the petition for administrative review by the AT (Articles 7 to 12 of the request), the Claimant refers expressly in article 13 the following: "in light of the foregoing, the now Claimant cannot accept the decision taken by the AT (read: the rejection of the petition for administrative review) since it understands not to be the passive subject of the tax in question, as will be demonstrated below;

  • Moreover, the AT itself does not conduct any analysis of the arguments invoked by the Claimant in the said administrative procedure, merely limiting itself to maintaining the responsibility for the tax on the now Claimant, confirming thus the previous decision;

  • The AT presented no justification for the rejection of the argumentation invoked by the Claimant, limiting itself to referring that it conducted a query to the IRN database (Institute of Registries and Notary);

  • The now Claimant understands that the justification of the Tax Authority is materially non-existent and therefore it was prevented from responding to it;

As to the alleged by the Respondent non-conformity of any merits of the request with the Constitution:

  • The Claimant disagrees with the Respondent's understanding, defending that following the formalist line of the Tax Authority to the detriment of the interpretation conferred by the Claimant would be, indeed, to disrespect principles and regulations constitutionally protected;

  • In truth, the Tax Authority seems to suggest that the constitutional principles that protect the legal position of the now Claimant such as the principle of contributory capacity and the principle of equivalence must be put aside in favour of the principles of legal certainty and/or trust, thus having only in view the blind collection of the tax and ignoring the true reality underlying the same.

3.2. Allegations of the Respondent

On 25 May 2016, the Respondent filed a request in which, alleging that the Claimant had exceeded the scope of the exceptional matter to which its right to respond was limited, it requested the removal of the same request from the case file or the consideration as not written of the part of the same request in which there was an excess of the right to respond.

By order of 12 June 2016, the Court considered that the Claimant had exceeded the scope of the exceptional matter for which it had been invited to exercise the right to be heard, having pronounced extensively on the substantive defence raised in the defence of the Respondent.

In accordance with this, the Court proposed that the meeting provided for in article 18 of the RJAT be dispensed with and that a period be granted to the Respondent to present written submissions.

Having this procedure been accepted by both Parties, a period was granted to the Respondent to present written submissions.

The Respondent presented written submissions, in which it reiterated the argumentation articulated in the defence.

II – SANITATION

The singular Arbitral Tribunal was regularly constituted on 26-02-2016, the arbitrator having been designated by the Ethics Council of the CAAD, the respective legal and regulatory formalities being complied with (articles 11, paragraph 1, letters a) and b) of the RJAT and articles 6 and 7 of the CAAD Ethics Code), and is competent ratione materiae, in accordance with article 2 of the RJAT.

The parties have legal personality and capacity, are legitimate and are regularly represented.

The joint consideration of the legality of 2 IUC assessments relating to the year 2011 is sought, whereby we are faced with a cumulation of claims.

The prerequisites provided for in paragraph 1 of article 3 of the RJAT and article 104 of the CPPT are verified in the concrete case, and cumulation is to be admitted by virtue of the identity of the tax and the circumstance that the analysis of the tax acts in question depends on the consideration of the same factual circumstances and the application of the same rules of law.

No procedural defects were identified.

III – QUESTIONS TO BE DECIDED

The following are the questions to be decided by the Court:

Preliminary question

  • Validity of the exception of time-barring of the request

Questions on the merits

  • The subjective incidence of the Unique Vehicle Circulation Tax in the year of the registration of the vehicle, in the event of the sale of the same vehicle in the same calendar year.

IV – FACTS FOUND PROVED

The following are the facts found to be proved and considered relevant for the decision:

1st: The Claimant is an importer of motor vehicles;

2nd On 14-07-2011 a customs declaration of vehicles (DAV) was issued in the name of the Claimant for the vehicle with chassis V…, to which was assigned, on the same date, the registration number …-… -…;

4th The price of the sale was paid on 05-08-2011;

5th On 10-08-2011, the Claimant registered in its name the ownership of the vehicle with the registration …-… -…;

6th On 12-08-2015 a collection document of the IUC was issued in the name of the Claimant relating to the vehicle with registration …-…-…, relating to the taxation year 2011, with the amount of tax to be paid of 142.77 euros, which was paid in full on 17-08-2015;

The facts found to be proved were so on the basis of the documents produced by the Parties for the case.

There are no facts with relevance to the judgment of the case considered not proved.

V - GROUNDS

Preliminary question: the exception of lapse of the right of action

Article 10, paragraph 1, of the RJAT provides that

1 - The request for constitution of an arbitral tribunal is presented:

a) "Within a period of 90 days, counted from the facts provided for in paragraphs 1 and 2 of article 102 of the Code of Procedure and Tax Process, as to the acts liable to autonomous challenge and, as well as, the notification of the decision or the end of the legal period for decision of the hierarchical appeal;"

For its part, article 16, paragraph 2, of the CIUC provides that "the assessment of the tax is made by the passive subject itself through the Internet, under the conditions of registration and access to electronic declarations."

Only in the event of non-assessment by the passive subject does the Tax Administration proceed with official assessment (under the terms of article 18, paragraph 2, of the CIUC). This was not what happened in the present cases, in which the Claimant proceeded with self-assessment of the tax.

Combining the provision in letter a) of paragraph 1 of article 10 of the RJAT with letter a) of paragraph 1 of article 102 of the Code of Procedure and Tax Process, it follows that, in the case where the act to be challenged is a self-assessment, the period for presentation of the request for arbitral pronouncement is 90 days and is counted from the end of the period for voluntary payment of the tax debt (Jorge Lopes de Sousa, Commentary to the Legal Framework for Arbitration in Tax Matters, in Nuno Villa-Lobos and Mónica Brito Vieira, Guide to Voluntary Arbitration, Almedina, Coimbra, 2013, p. 164).

Like the period for bringing judicial action, the period for bringing a request for arbitral pronouncement is a period of lapse and has substantive nature, as is established in article 20 of the CPPT, being counted in accordance with the provision in article 279 of the CCivil, that is, in a continuous manner, without suspensions, in particular, on Saturdays, Sundays and public holidays or during periods of judicial recess, only in the event that the period ends during these days or period, its end is transferred to the first working day following the same.

The collection documents issued indicate as the payment period the day 24-10-2011 (for the collection document 2011…) and the day 13-02-2012 (for the collection document 2011…).

Obviously these are the periods in which payment should have been made in the event that the self-assessment had been effected within the legal period established in article 17, paragraph 1, of the CIUC, which was not the case.

As this period does not apply, nor any other specifically provided, the period for voluntary payment of the tax debts in question was 30 days, as per article 85, paragraph 2, of the CPPT. The collection documents having been issued on 12-08-2015, the periods would therefore end on 11-09-2015, the date from which the 90-day period provided for in letter a) of paragraph 1 of article 10 of the RJAT would begin to be counted and which would end on 10 December 2015.

Having the request been presented on 30 November 2015, it must be concluded that the presentation of the request for arbitral pronouncement is not time-barred, and therefore the exception of lapse of the right of action is groundless.

The subjective incidence of the Unique Vehicle Circulation Tax in the year of registration of the vehicle, in the event of sale of the same vehicle in the same calendar year.

As to the subjective incidence of the unique vehicle circulation tax, article 3 of the respective code governs, which stated, in its paragraph 1, at the time of the tax facts that gave rise to the assessments challenged, that the passive subjects of the tax are the owners of the vehicles, considered as such the natural or legal persons, of public or private law, in whose names such vehicles are registered.

There is abundant jurisprudence, especially from arbitral tribunals, to the effect that this provision contained a presumption, regarding the determination of who was the owner of a vehicle.

Therefore, the owner of a vehicle was a passive subject regardless of whether there was property registration in its name, but where there was property registration in the name of a given holder, it was presumed that he was the actual holder of the right.

As to the temporal incidence, article 4 of the same statute governs, which contains two rules:

The first, that of periodicity and annuality of the tax: the tax is annual and is due in full in each year to which it relates;

The second rule, contained in paragraph 2 of the provision, tells us – not very clearly it must be said – when the tax event is deemed to have occurred.

The following is the text of paragraph 2 of article 4:

"2 - The taxation period corresponds to the year that begins on the date of registration or on each of its anniversaries, for vehicles in categories A, B, C, D and E, and to the calendar year, for vehicles in categories F and G."

Therefore: the tax is annual, which means that it relates to a period of 12 months. This period of 12 months does not necessarily coincide with the calendar year. The first taxation period begins on the date of registration. Subsequent periods begin on the anniversary date of the registration.

Let us apply the rule to the two concrete cases:

For the vehicle with registration …-… -…, the date of registration is 14-07-2011. On this date the first taxation period of 12 months begins, for this vehicle.

For the vehicle with registration …-… -…, the date of registration is 12-12-2011. On this date the first taxation period of 12 months begins, for this vehicle.

But if it is true that the taxation period begins on that date, the same period only ends one year later. If several owners succeed one another throughout the period, which of them is the passive subject? The first or the last? In the field of Municipal Property Tax, for example, which also relates to ownership and is also a tax of annual periodicity, the passive subject is the owner on the last day of the taxation period (article 8, paragraph 1 of the CIMI).

Now, neither article 4 nor article 3 of the CIUC provide an answer to this question.

However, paragraph 3 of article 6, always of the CIUC, determines that "the tax is considered exigible on the first day of the taxation period referred to in paragraph 2 of article 4." If the tax is exigible on the first day of the taxation period, this means that on that date the tax event is deemed to have occurred and the tax obligation to have been constituted, which obviously necessarily has a passive subject. If this is so, one can only conclude that the passive subject of the tax is whoever is the owner of the vehicle on the first day of the taxation period.

Let us see who was the owner of the two vehicles in question on the first day of taxation of the first taxation year in the case of the two vehicles. We already know that the day of interest to us is the day of registration.

Now, on the day of registration, the owner of the two vehicles was indisputably the Claimant, not only because the registration was issued in its name on that same day, but also because the Claimant proceeded with the registration of ownership in its name, and furthermore because the sales contracts provide that the ownership of the vehicles remains with the Claimant until full payment of the respective value, which only came to occur at a later date.

From this it must be concluded that, in the two cases at hand, the owner of the vehicles on the first day of the taxation period was the Claimant, and for that reason, it is also the passive subject of the tax.

In this conformity, it must be concluded that the assessments challenged do not suffer from any illegality, in particular by way of error as to the legal and factual premises of the application of the applicable law.

VI. DECISION

For the grounds set forth, this Court decides to judge the present arbitral request entirely groundless.

Value of the economic utility of the case: The value of the economic utility of the case is fixed at 283.89 euros.

Costs: Under article 22, paragraph 4, of the RJAT, the amount of the costs is fixed at 306.00 euros, under Table I attached to the Costs Regulation in Tax Arbitration Procedures, to be borne by the Claimant.

Let this arbitral decision be registered and notified to the parties.

Frequently Asked Questions

Automatically Created

Who is the taxable person for IUC in the year of vehicle registration in Portugal?
The taxable person for IUC in the year of vehicle registration is the owner as registered in the Vehicle Registry, pursuant to Article 3(1) of the CIUC. In practice, this means the person in whose name the vehicle is officially registered when the tax obligation arises. For newly imported vehicles, this is initially the importer who must register the vehicle to obtain the registration certificate, even if the vehicle is intended for immediate resale.
Can a vehicle dealer be held liable for IUC after transferring ownership within the legal registration period?
Yes, according to the Tax Authority's position in this case. When a dealer imports and registers a vehicle, they become the first registered owner and thus the IUC taxable person for that taxation period under Articles 3 and 6 of the CIUC, regardless of subsequent sale and re-registration within the 60-day legal period. However, the dealer argues that Article 18(1)(a) interpreted by contrario means liability only attaches when re-registration does NOT occur within the legal timeframe, making this a contested legal issue.
What does Article 3(1) of the Portuguese IUC Code establish regarding subjective tax incidence?
Article 3(1) of the Portuguese IUC Code establishes that the passive subjects (taxable persons) of the tax are the owners of vehicles, defined as the natural or legal persons in whose names such vehicles are registered in the Vehicle Registry. This provision creates a direct link between formal registration and tax liability, making the registered owner presumptively liable for IUC obligations.
How does the 60-day legal registration period affect IUC liability for newly matriculated vehicles?
The 60-day legal registration period creates ambiguity regarding first-year IUC liability. Dealers argue that when vehicles are sold and re-registered to purchasers within this 60-day window following initial matriculation, the purchaser becomes the taxable person because the re-registration occurs within the legally required timeframe. Article 17(1) requires self-assessment within 30 days after this registration period ends, suggesting the person registered at that point bears liability. However, the Tax Authority maintains that the initial registrant remains liable regardless of timely transfers.
What are the legal grounds for challenging an unlawful IUC assessment before the CAAD tax arbitration tribunal?
The legal grounds for challenging an unlawful IUC assessment before the CAAD tax arbitration tribunal include: (1) illegality of the assessment due to errors in legal or factual premises relating to the tax event; (2) incorrect determination of the taxable person under Article 3(1) CIUC; (3) misapplication of Articles 6, 17, or 18 of the CIUC regarding tax incidence, assessment timing, or registration requirements. The challenge must be filed within 90 days from the end of the voluntary payment period under Article 10 of Decree-Law 10/2011 (RJAT), though administrative review proceedings may affect this deadline.
