Tax Type: IRS

Source: Original CAAD Decision

Summary

This arbitral decision addresses a complex IRS dispute involving the taxation of €13.5 million received by a taxpayer who acquired litigious litigation rights through a credit assignment contract in 2007. The taxpayer ultimately received compensation from the Portuguese State in 2010 for land expropriated for school construction. After multiple IRS assessments for the 2010 tax year, one assessment was successfully challenged and annulled by the CAAD arbitral tribunal in June 2013 due to classification and quantification errors. The central legal controversy arose when the Tax Authority issued a new IRS assessment in December 2014 (totaling €6.77 million plus compensatory interest), reclassifying the income as Category E capital gains rather than the previous classification. The taxpayer contested this new assessment on three primary grounds: first, that the 2013 arbitral decision had become final and binding, precluding any reassessment; second, that the principle of preclusion prevented the Tax Authority from re-litigating the same facts for the same taxpayer and taxation period; and third, that any taxable increase in assets from the 2007 credit assignment should have been attributed to that year, making the 2010 assessment time-barred. The case raises fundamental questions about the scope of Article 24(4) of the RJAT (Legal Framework for Tax Arbitration), which governs the Tax Authority's powers after judicial annulment of tax acts. Specifically, whether administrative preclusion applies when a previous assessment is annulled for substantive classification errors, and whether the Tax Authority retains authority to issue new assessments with different legal qualifications for the same underlying economic transaction. The decision has significant implications for taxpayers' legal certainty and the limits of tax reassessment powers following arbitral annulment.

ARBITRAL DECISION

I. Report

  1. A..., tax payer nº..., resident at Avenida..., nº..., in Cascais, hereinafter referred to as the Petitioner, filed on 13 April 2015, a request for constitution of an arbitral tribunal, in accordance with the provisions of numbers 1 and 2 of the Legal Framework for Tax Arbitration (RJAT), contained in Decree-Law nº 10/2011, of 20 January.

  2. In the request for arbitral ruling, the Petitioner declared not intending to proceed with the appointment of an arbitrator, whereby the constitution of the Arbitral Tribunal proceeded in accordance with the provisions of nº 1 of article 6 and nº 1 of article 11 of the RJAT, with the arbitrators José Poças Falcão, José Nunes Barata and Paulo Lourenço being appointed.

On 9 June 2015 the parties were notified of this appointment, having manifested no intention to refuse the appointment of the arbitrators, with the Arbitral Tribunal being considered constituted on 25 June 2015, in accordance with paragraph c) of nº 1 of article 11 of the RJAT.

By order of 5 October 2015, the Arbitral Tribunal dispensed with the meeting referred to in article 18 of the RJAT, considering that it is a case not subject to specific procedural formalities, that the principle of contradictory procedure was observed and a written reply was presented by the Petitioner and there is no apparent need for correction of the procedural documents.

Similarly, oral evidence was dispensed with, taking into account that the evidence will be essentially documentary in nature.

  1. The claim that is the subject matter of the request for arbitral ruling consists in the declaration of illegality of the Income Tax (IRS) Assessment and Compensatory Interest nº 2014 ..., of 12 December 2014, relating to the year 2010, in the amount of € 6.770.549,16, with its consequent annulment.

  2. The Petitioner sustains, in summary, its claim in the following:

4.1. B... and his mother, C..., were owners of the mixed property called Quinta..., composed of warehouses, outdoor area and rural portion.

4.2. The Portuguese State began, in 1983, the construction of the so-called School..., including a gymnasium-sports pavilion and a playing field, without having paid any amount to the respective owners.

4.3. By succession from his mother, C..., B... became the sole holder of the said property as from 2001.

4.4. On 15 October 2002, B... and his wife, D..., instituted a revendication action against the Portuguese State, requesting the return of the property in their ownership, compensation for damages arising from its occupation as from 1983, accrued and accruing interest relating to the price of the sale, judicial costs and extrajudicial expenses.

4.5. On 24 April 2007 the Petitioner entered into a contract for cession of litigious claims with the aforementioned B... and his wife, whereby he acquired all the rights that were to be declared and recognized in the said case, including any compensation that was to be liquidated.

4.6. Later, on 26 April 2007, the Petitioner requested to be admitted as a party to the respective action and expanded the claim, which was granted by the Court.

4.7. In the judgment of the ... Mixed Court of Sintra, of 30 May 2008 it was decided to recognize B... as owner of the property called "Quinta...", to recognize to the State the right of accession of the part occupied by School..., condemning it to pay to the admitted party, now Petitioner, the sums of € 8.625.000 for this acquisition, of € 3.819.812,50, for the depreciation of the remaining area of the property and default interest on these amounts, at the legal rate in force, from the date of the judgment until full payment.

4.8. An appeal was filed to the Lisbon Court of Appeal, which altered the decision, ceasing to recognize to B... the ownership of the parcel of land occupied by Secondary School..., including the playing field and the sports pavilion, declaring that it would be the property of the State after payment of the compensation corresponding to € 8.625.000.

4.9. An appeal for review was filed to the Supreme Court of Justice, which confirmed the Court of Appeal in full, with the Petitioner filing an execution action against the Portuguese State on 10 February 2010.

4.10. On 23 August 2010, the Portuguese State paid the Petitioner the sum of € 13.483.166,74.

4.11. In the judicial proceedings, the Petitioner paid the sums of € 726.000, of attorney's fees, of € 310.533,79, of costs and other judicial expenses, of € 183.624,06, of withholding tax, of € 695.546, of compulsory pecuniary sanction that reverted to the State and of € 834.654,75, of refund to the Portuguese State.

4.12. On 30 July 2011, the Petitioner filed his Income Tax declaration nº ...-... -..., relating to the year 2010, which gave rise to the Income Tax assessment nº 2011..., of 14 July 2011, with the amount due of € 5.771,15.

4.13. On 21 November 2011, the local Finance Service carried out a new Income Tax assessment, which corresponds to nº 2011..., relating to the same year 2010, with the amount due of € 327.986,50.

4.14. On 28 November 2011, the Petitioner filed a replacement Income Tax declaration nº ...-..., relating to the year 2010, which determined that on 5 December 2011, the Finance Service of Lisbon ..., proceeded with a new Income Tax assessment, with nº 2011..., from which resulted tax due in the amount of € 339.223,32.

4.15. Through service order nº OI 2011..., of the Inspection Services of the Finance Directorate of Lisbon, an external inspection procedure was carried out on the Petitioner.

4.16. On 28 November 2011 a new replacement declaration was presented, which was based on a document issued by the General Secretariat of the Ministry of Finance and Public Administration, which shows the income for the year 2010 as the amount of € 1.112.873,10.

4.17. A new Income Tax assessment was carried out in relation to the year 2010, which corresponds to nº 2012..., from which resulted tax due in the amount of € 5.882.782,02.

4.18. Not accepting the tax act in question, the Petitioner filed with the CAAD, on 1 July 2013, a request for arbitral ruling for declaration of illegality.

4.19. By decision of 17 June 2013, the Arbitral Tribunal declared the Income Tax assessment for the year 2010 illegal, due to error of classification and quantification, a decision which has already become final and binding.

4.20. Through official communication nº..., of 4 November 2014, repeated on 19 November 2014, by official communication..., of the Division for Assessment of Income Tax and Expenditure, of the Finance Directorate of Lisbon, the Petitioner was notified to comment on the draft decision relating to Income Tax for 2010, in accordance with the provisions of article 60 of the General Tax Law.

4.21. The notifications in question informed the Petitioner that the income paid by the Portuguese State, in the amount of € 13.666.790,81, are subject to taxation, as income from capital (category E).

4.22. On 23 December 2014, the now Petitioner was notified of the Income Tax assessment nº 2014..., of 12 December 2014, relating to the year 2010, in the amount of € 6.778.549,16.

4.23. As payment was not effected within the voluntary payment period, the Petitioner was cited on 8 February 2015, with a view to payment, dation in payment or the filing of an opposition to execution.

4.24. The esteemed arbitral decision, according to the Petitioner, became final and binding on 24 July 2013 and is binding on the Tax Authority.

4.25. The Tax Authority cannot re-enact the assessment, once preclusion or extinction of the purported right has occurred, taking into account that we are dealing with the same taxpayer, the same facts and the same taxation period.

4.26. Furthermore, the Petitioner holds that any eventual increase in assets resulting from the contract for cession of litigious claims would always be imputable to the year 2007, and therefore no tax could be demanded, since article 45 of the General Tax Law requires that the notification of the assessment be validly effected within the period of 4 years, which had already elapsed.

4.27. Article 24 of the RJAT, interpreted with the scope that it has now been given by the Tax Authority, to the effect of permitting unrestricted re-examination and alteration of the tax assumptions of fact and law applicable, disregarding the authority, obligation and inviolability of the judgment, which integrates a constitutionally protected value, would always be unconstitutional and inapplicable to the concrete case.

4.28. The amounts received by the Petitioner correspond to the reintegration in the patrimony of the injured party of the value corresponding to the claimed property, losses which he was obliged to bear and prejudices which were caused to him by delays of the Portuguese State in complying with judicial decisions, and thus the imposition of taxation in Income Tax on such compensation violates the constitutional principles set forth in articles 2, 9, 18, 62 and 266 of the Constitution of the Republic.

4.29. The interpretation of the Tax Authority further violates the principle of equality, since the patrimonial loss affects only the Petitioner and not the generality of citizens in whom there is a restitution in natura of the properties unlawfully occupied, creating an arbitrary negative discrimination.

4.30. The assessment violates the principles of legality, justice and proportionality, as they imposed the payment of a tax that was not legally due, with respect to amounts that were merely intended to repair damages judicially proven and losses, in accordance with the provisions of article 55 and following of the General Tax Law.

4.31. The assessment suffers from errors of fact and law, since it being indisputable the non-existence of a tax fact, the charges and expenses borne in the context of judicial proceedings were not considered, thereby violating article 74 of the General Tax Law and article 100 of the Code of Tax Procedure and Process.

4.32. The Tax Authority did not hear the Petitioner before the pronouncement of the assessments, a situation that frontally violates the provisions of article 60 of the General Tax Law.

4.33. The assessment suffers from lack of factual and legal justification.

4.34. The Tax Authority, in its reply, sustains, by way of exception, that the Petitioner raised, on 8 February 2015, an opposition to execution, seeking, not only through judicial impeachment, but also through this procedural means, to review the tax assessment.

4.35. It is manifest the use of various judicial procedural means with a view to annulment, a situation which gives rise to a situation of lis pendens.

4.36. Even if lis pendens does not occur, the truth is that we are dealing with a prejudicial issue, since the eventual success of the opposition to execution could make the collection of the levied tax impossible.

4.37. The Tax Authority proceeded with the annulment of the first assessment in implementation of the judicial decision, and thus, with its becoming final and binding, the duty of spontaneous execution was exhausted.

4.38. The judgment bars the repetition of the case when there is identity of subjects, identity of the claim and identity of the cause of action.

4.39. The greater purpose of res judicata is to prevent contradiction of judgments, which means that it will always be measured in function of the tenor of the decision with respect to its objective scope.

4.40. The Tax Authority could not, in light of the principles of legality, indisponibility of tax credits and material truth, fail to assess, in due time, the tax on the income obtained by the Petitioner.

4.41. Resulting from the records that a periodic tax (Income Tax) is in question and respecting the same to the year 2010, the limitation period began on 31 December 2010, whereby, no suspensive or interrupting fact occurring, the period would only lapse on 31 December 2014.

4.42. The assessment was effected on 12 December 2014 and notification carried out on 23 December 2014, consequently within the limitation period, reason whereby it does not appear legitimate to invoke the extinction of tax powers by preclusion and expiration in the case under consideration.

4.43. The principle of legal certainty stems from the constitutional prohibition on retroactivity of tax rules, a matter not discussed in the proceedings, whereby the controversy of succession of laws in time proves to be unnecessary to place in crisis in the tax assessment procedure.

4.44. For its part, the constitutional protection of trust emanates from the principle of the rule of law and seeks to safeguard legal subjects against unjustifiably unforeseeable actions, which did not occur in the concrete case under consideration, since the Tax Authority cannot be charged with arbitrariness either in the legal-juridical framework of the tax fact or in the tax assessment act that followed it, as it did not affect already constituted legal positions nor was it disproportionate.

4.45. The Tax Authority cannot be imputed the violation of the principle of good faith, since the assessment of a tax that is due does not prove to be ineffectual and taxing an income in accordance with contributory capacity does not translate a discretionary or unnecessary act.

4.46. It cannot be justified that a taxpayer who obtained an income of € 13.666.790,81 is not obliged to pay a tax in accordance with that income, as this is clearly an affront to the principle of contributory capacity and, all the more, to the principle of equality.

4.47. Any interpretation of article 24, nº 4 of the RJAT that would come to restrict the limitation period established in article 45, nº 1 of the General Tax Law, will suffer from organic unconstitutionality.

4.48. It does not appear, in the concrete case under consideration, that any guarantee of the Petitioner has been restricted, since, despite the justification contained in the assessment having been summary, as is legally admissible, it results from adherence to the matter of fact and law appraised by the CAAD in a previous process, having been moreover communicated to the Petitioner this circumstance in the information sent to him by the Division of Income Tax Assessment of the Finance Directorate of Lisbon, for purposes of the right to be heard.

4.49. It has been a uniform understanding that the right to be heard of the interested parties can be dispensed with when the Tax Authority carries out an act based on facts already submitted in another phase of the procedure to the hearing of the interested parties.

II. Factual Justification

  1. Being the issues purely of law, are considered definitively established, given the absence of controversy of the parties and the supporting documents incorporated in the proceedings and the administrative instruction process, the facts referred to in the procedural documents presented, to which reference is made and, specifically, that the facts which gave rise to the tax act under challenge are the same as those which gave rise to the assessment that is the subject of process nº 7/2013-T, published at www.caad.org.pt., with divergence being found only in the legal classification of the same, the earlier assessment being based on the provisions of article 3-1/a) of the IRS Code (Category B - Professional and business income) and the current one is based on the provisions of article 5-1 and 2 of the IRS Code (category E – Income from capital application).

III. Legal Justification

1. On lis pendens and on the prejudicial issue

  1. In accordance with the provisions of nº 1 of article 580 of the Code of Civil Procedure, the exceptions of lis pendens and res judicata presuppose the repetition of a cause; if the cause is repeated while the earlier one is still pending, there is lis pendens.

Nº 2 of the same article, for its part, provides that both the exception of lis pendens and that of res judicata are aimed at preventing the court from being placed in the alternative of contradicting or reproducing a previous decision.

Nº 1 of article 581 of the Code of Civil Procedure stipulates that the cause is repeated when an action identical to another is proposed as regards the subjects, the claim and the cause of action.

In the concrete case under consideration, the Tax Authority understands that lis pendens occurs due to the fact that, alongside the present process, the Petitioner filed on 8 February 2015 an opposition to execution, seeking, in one case and the other, to annul the tax assessment.

However, the Tax Authority is not, with due respect, correct, since, as results from the conjunction of articles 99 and 203, both of the Code of Tax Procedure and Process, neither the identity of the claim nor that of the cause of action occurs, taking into account that the grounds are different.

In effect, the cause of action in the impeachment process concerns the legality of the assessment act, namely the erroneous quantification and classification of income, profits, patrimonial values and other tax facts, as well as lack of competence, lack of justification and omission of legal formalities, while in opposition to execution the cause of action is based on the non-existence of the tax, the illegitimacy of the persons cited, the falsity of the documents, the prescription of the debt, lack of notification, payment and duplication of collection, among other illegalities that are not susceptible to discussion within the scope of the impeachment process.

The analysis of the grounds of opposition to execution allows one to conclude that they have nothing to do with the assessment act itself, since this, as mentioned, can only be discussed within the scope of judicial impeachment or friendly administrative recourse.

Furthermore, the claim to be made within the scope of judicial impeachment is that of annulment, on grounds of illegality, of the tax assessment, while in opposition to execution the claim is based on the extinction of the tax debt that was created as a result of the assessment procedure.

It is not even relevant the fact that it is intended to call into question the assessment through the two aforementioned routes, since the incorrect use of procedural means is not susceptible to contravening what is provided for in the law.

All considered, there being no identity of claims nor even of cause of action, it can then be concluded that lis pendens does not occur, with the exception invoked by the Tax Authority therefore being unfounded.

Equally, there is no existence of any prejudicial issue, since, due to the fact that defects are invoked that may conflict with the grounds of opposition to execution, that does not mean that they will be judged to be well-founded or that they will come to be known outside their proper place.

There is no, in reality, any issue that has to be discussed and judged within the scope of the present process that is essential for the decision that is to be taken in opposition to execution.

2. On the Income Tax Assessment

  1. Let us now analyze the substantive issue which reduces to the appraisal of the illegality of the Income Tax assessment.

In question is income obtained by virtue of the acquisition of a litigious claim, through cession of claims, a situation which the Tax Authority now understands, through a new assessment, is susceptible of integration within the scope of application of article 5 of the Income Tax Code.

Let us see if this is so.

It is recalled, in the first place, that the matter in question was discussed and judged within the scope of process nº 7/2013, a decision in which it was concluded that, as the correct legal framework of the tax fact was not carried out by the Tax Authority, the assessment was annulled, due to the defect of erroneous classification and quantification of income (article 99, paragraph a) of the Code of Tax Procedure and Process).

The fundamental issue that arises in the present process is that of knowing what are the legal effects that flow from the annulment of a tax act.

Specialized doctrine has already examined this subject, as can be seen through the study of Prof. Alberto Xavier, Fundamental Aspects of Tax Litigation, Notebooks of Science and Technique of Taxation, Center for Tax Studies of the General Directorate of Contributions and Taxes, Ministry of Finance, Lisbon 1972.

In the work cited above, the author, at pages 85 and following, refers in a clear and unequivocal manner that "If the tax act was annulled on the ground of lack of competence or defect of form, the Tax Administration must practice it again, provided that it does not reproduce in the new act the defect determining the annulment of the earlier one. But, if instead, the reason for annulment lies in a violation of law, the Tax Administration no longer has, in the content of its duty to execute the sentence, the practice of positive acts in substitution of the annulled illegal act. In the case where the violation of law refers to the very existence of the tax obligation, that is, in the case where it is a total annulment, of the tax act nothing remains and the Administration must refrain from practicing a new act with respect to the same obligation."

By way of conclusion, sustains the aforementioned author, that "…the tax act annulled for lack of competence and defect of form is a renewable act; the tax act annulled for violation of law is an irrenovable act."

In another work of the same author, Concept and Nature of the Tax Act, Dissertation of Doctorate in Legal-Economic Sciences at the Faculty of Law of the University of Lisbon, Livraria Almedina, Coimbra, 1972, p. 575 and following, it is referred that "More important than the choice of adequate terminology is, however, the substantive question that is underlying and that is to know whether res judicata is the strict prerogative of jurisdictional acts or whether it also applies to administrative acts, especially those that are bound."

Further on, the aforementioned author emphasizes that "The aforementioned defense instruments of the abstraction generated by the tax act take on the nature of procedural preclusions, that is, limits on the power of re-examination or re-appraisal of the tax situation that is the subject of the process."

Such as res judicata, continues the mentioned author, …"also procedural preclusions may concern the powers of appraisal of the act in the process in which it was practiced, as may concern the powers of appraisal of the act in a later and distinct process."

Finally, concludes the cited author, "These means translate themselves in the impeachment process or concern the execution process; once, however, the respective periods have elapsed or its unfoundedness is verified, the abstract legal situation defined by the tax act consolidates itself definitively, with its external preclusion operating."

In the context of Tax Arbitration, the principle of preclusion of the right to practice a new tax act with respect to the same taxpayer or tax debtor and taxation period is established following the pronouncement of an annulling arbitral decision, with the exception only being the case where the justification of the act is based on new facts different from those that motivated the arbitral decision – See article 24-4, of the RJAT.

Certainly the Tax and Customs Authority, within the scope of its duties to execute arbitral decision in favor of the taxpayer, until the end of the period provided for spontaneous execution of the decisions of the judicial tax courts (emphasis ours), can, in particular, practice the legally due tax act in substitution of the act that is the subject of the arbitral decision, restore the situation that would exist if the tax act that is the subject of the arbitral decision had not been practiced, liquidate the tax obligations in accordance with the arbitral decision or refrain from liquidating them – See article 24-1/a), b) and d), of the RJAT.

Even if it can be understood – and the Tribunal by no means holds such understanding as certain – the interpretation of the provisions of nº 4 in harmony with paragraphs a) and b) of nº 1, both of the cited article 24, of the RJAT, that is, that, as a result of the duty to execute the judgment, the practice of the new act within the period for that execution would be permitted and legal, in the concrete case the practice of the assessment act took place far beyond that period.

All considered, it can then be concluded that in the concrete case under consideration procedural preclusion occurred, which means that it was definitely barred from the Tax Authority the performance of a new assessment in substitution of the earlier one, unless new facts had arisen, which manifestly did not occur, since the only difference that is possible to detect concerns the different legal framework of the income earned by the Petitioner.

Contrary to what occurs in relation to res judicata, the occurrence of procedural preclusion only permits that a tax act be practiced in substitution of the earlier one if supervening facts occur.

A similar understanding can be gleaned from the judgment of the Administrative Supreme Court nº 01035/15, of 7 October 2015, in the part where it seeks to provide an answer to the question of clarifying that "…the eventual preclusion of the right of the defendant to present a new request for waiver of provision of guarantee…", implies that one knows whether or not "…supervening facts were invoked that justified the presentation of a new request in accordance with nº 2 of article 170 of the Code of Tax Procedure and Process."

There being no supervening facts, the Income Tax assessment carried out is illegal, and for that reason, it should be annulled.

It is not justified to appraise the other issues raised by the Petitioner, which are barred by the declaration of illegality of the assessment.

III. Decision

Given that, it is decided to wholly uphold the request for arbitral ruling, annulling, for manifest illegality, the Income Tax assessment nº 2014..., of 12 December 2014, relating to the year 2010, in the amount of € 6.770.549,16, as well as the respective compensatory interest.

The value of the process is fixed at € 6.770.549,16 in accordance with article 97-A, nº 1, paragraph a) of the Code of Tax Procedure and Process, applicable by virtue of paragraphs a) and b) of nº 1 of article 29 of the RJAT and nº 2 of article 3 of the Regulation of Costs in Tax Arbitration Proceedings.

The value of the costs of the process is fixed at € 84.762,00, in accordance with Table I of the Regulation of Costs of Tax Arbitration Proceedings, to be paid in full by the Respondent, since the Petitioner obtained full acceptance of the claim, in accordance with nº 2 of article 12 and nº 4 of article 22 of the RJAT and nº 3 of article 4 of the cited Regulation.

Frequently Asked Questions

Automatically Created

How are taxable income proceeds qualified under Portuguese IRS rules in cases involving credit assignment of litigious claims?
Under Portuguese IRS rules, income from assignment of litigious claims (cessão de créditos litigiosos) presents complex qualification challenges. When a taxpayer acquires litigation rights through a credit assignment contract and subsequently receives court-awarded compensation, the tax treatment depends on the nature of the underlying claim and timing. If the assignment contract itself generates an immediate gain (difference between acquisition price and value of rights acquired), this constitutes a capital gain taxable in the year of assignment under Category G. However, amounts received years later when the litigation concludes may be taxable as Category E (capital income) or Category G (capital gains) depending on whether they represent returns on the acquired credit or realization of the credit itself. The Tax Authority must analyze the economic substance of the transaction, the nature of the judicial award (compensation for expropriation, damages, interest), and whether the income accrued to the original right-holders or derives from the assignment contract. Portuguese tax authorities have increasingly scrutinized such transactions to prevent tax avoidance through timing manipulation and improper income characterization.
What happens when a tax assessment is judicially annulled under Portuguese tax law?
When a tax assessment is judicially annulled under Portuguese tax law, the legal effects depend on the grounds for annulment and applicable procedural rules. Under Article 24(4) of the RJAT, judicial annulment of a tax assessment does not automatically preclude the Tax Authority from issuing a new assessment, provided the annulment was based on formal defects, procedural violations, or correctable substantive errors, and the statute of limitations has not expired. The annulment creates a legal vacuum, returning the situation to its state prior to the defective assessment. However, the Tax Authority's power to reassess is not unlimited: it must respect res judicata principles, cannot relitigate facts definitively established by the court, and must comply with statutory limitation periods. If the annulment was based on substantive grounds (such as incorrect legal qualification or quantification errors), the Tax Authority may issue a corrected assessment addressing those specific defects, but cannot simply reissue an identical assessment. The new assessment must remedy the vices that led to annulment and can be challenged through normal administrative and judicial review procedures. Compensatory interest accrued on the annulled assessment is also cancelled, and any amounts paid must be refunded with compensatory interest.
Can the Portuguese Tax Authority issue a new tax act after the annulment of a prior IRS assessment under Article 24(4) of the RJAT?
Yes, Article 24(4) of the RJAT explicitly permits the Portuguese Tax Authority to issue a new tax act after annulment of a prior IRS assessment by an arbitral tribunal, subject to specific conditions and limitations. This provision recognizes that annulment for formal defects, procedural irregularities, or correctable substantive errors should not result in definitive preclusion of the State's taxation power when the substantive tax obligation remains valid. However, this authority is constrained by several principles: (1) the statute of limitations for assessment must not have expired; (2) the Tax Authority cannot relitigate factual or legal issues definitively resolved by the arbitral decision (res judicata effect); (3) the new assessment must address and remedy the specific defects identified in the annulment decision; (4) procedural guarantees, including prior hearing rights under Article 60 of the LGT (General Tax Law), must be scrupulously observed; and (5) the principle of administrative preclusion may apply if the new assessment attempts to relitigate identical facts and legal qualifications already rejected. The rationale is that while taxpayers deserve protection from defective administrative acts, annulment should not create windfall benefits when legitimate tax obligations exist. Courts have emphasized that this power is not carte blanche for indefinite reassessment but must balance legal certainty, taxpayer protection, and fiscal equity. The Tax Authority bears the burden of demonstrating that the new assessment complies with these constraints and addresses substantively different legal grounds than those rejected in the annulled assessment.
What is the procedure for filing an arbitral claim against an IRS assessment at the CAAD tax arbitration tribunal?
The procedure for filing an arbitral claim against an IRS assessment at the CAAD (Centro de Arbitragem Administrativa) follows the framework established in the RJAT (Legal Framework for Tax Arbitration). The taxpayer must submit a formal arbitration request within 90 days from notification of the final administrative decision rejecting a prior administrative challenge (hierarchical appeal or review), or directly within the same 90-day period if opting to bypass administrative remedies as permitted by law. The request must be filed electronically through the CAAD platform, identifying the contested tax act (assessment number, year, amount), stating the legal and factual grounds for illegality, and paying the required arbitration fee (calculated as a percentage of the disputed amount, subject to minimum and maximum limits). The taxpayer may appoint a specific arbitrator or allow the CAAD to appoint the tribunal, which typically consists of a single arbitrator for claims under €10,000 and three arbitrators for higher amounts. After constitution of the tribunal (within specified deadlines), both parties present written submissions, with the Tax Authority filing a defense. The tribunal may order document production, schedule hearings if necessary, and must render a decision within six months (extendable). CAAD decisions have the same force as judicial court judgments, are immediately enforceable, and can only be challenged through narrow grounds before regular courts (jurisdictional issues, violation of public policy). This alternative dispute resolution mechanism offers speed, specialization, and efficiency compared to traditional tax litigation in administrative courts.
What are the legal consequences of compensatory interest on an annulled IRS assessment totaling over €6.7 million?
The legal consequences of compensatory interest (juros compensatórios) on an annulled IRS assessment exceeding €6.7 million are significant under Portuguese tax law. When an assessment is annulled by arbitral decision, all accessory obligations including compensatory interest are automatically extinguished ab initio, as they derive from and depend on the validity of the principal tax debt. If the taxpayer paid any amounts (principal or interest) related to the annulled assessment, Portuguese law mandates full reimbursement plus compensatory interest calculated from the payment date until actual refund, at rates established annually by ministerial order (typically 4-5% annually). For an assessment of €6.7 million, the compensatory interest burden on the Tax Authority for delayed refunds can be substantial, potentially hundreds of thousands of euros depending on payment timing and refund delay. However, if the Tax Authority issues a new valid assessment under Article 24(4) RJAT after the annulment, compensatory interest begins accruing anew from the end of the voluntary payment period for the new assessment. The taxpayer cannot be held liable for compensatory interest related to the period when the annulled assessment was in effect, as this would violate the principle that annulled acts are void ab initio. In enforcement proceedings, suspension of collection during the arbitration prevents accumulation of interest during that period. These rules balance protecting taxpayers from consequences of illegal administrative acts while preserving the State's legitimate interest in collecting validly assessed taxes. Any errors in compensatory interest calculation can be independently challenged through administrative procedures or judicial review.
