Summary

This CAAD arbitration decision (Process 523/2017-T) addresses the competence of tax arbitration tribunals to review IRS assessments based on indirect methods and unjustified wealth increases. Taxpayers A and B challenged additional IRS assessments for 2012 and 2013 totaling €295,210.32, resulting from bank deposits they could not fully justify with documentation. The Tax Authority (TA) applied indirect assessment methods under Article 89-A of the IRS Code after the taxpayers failed to provide supporting documents for deposits in account F, despite justifying other accounts. The taxpayers argued they had provided all available documentation and that the law requiring such documentation (Law 55-A/2012) only applied to facts occurring after its entry into force. The TA raised three preliminary exceptions: (1) material incompetence of CAAD to review indirect assessment methods, (2) res judicata from a prior Lisbon Tax Court decision, and (3) impropriety of the arbitral remedy chosen. The tribunal had to determine whether it had jurisdiction to hear challenges involving the application of indirect taxation methods, a fundamental question about the scope of tax arbitration in Portugal. The decision clarifies the boundaries between judicial and arbitral competence in Portuguese tax law, particularly regarding complex assessment procedures involving unjustified wealth increases and indirect methods, which are critical enforcement tools for the Tax Authority when taxpayers cannot substantiate the origin of their financial resources.

ARBITRAL DECISION

REPORT

  1. A… and his wife, B…, taxpayers … and …, respectively, residing at …, …, …-… …, having been notified of the additional Personal Income Tax (PIT) assessments for the years 2012 (2017…, of 24 May, 2017…, of 30 May) and 2013 (2017…, of 26 May and 2017…, of 21 June), in the amounts of, respectively, € 126,527.54 (one hundred twenty-six thousand five hundred twenty-seven euros and fifty-four cents) and € 168,682.78 (one hundred sixty-eight thousand six hundred eighty-two euros and seventy-eight cents), totalling € 295,210.32 (two hundred ninety-five thousand two hundred ten euros and thirty-two cents), on the grounds that unjustified asset increases exist, have, pursuant to article 2(a)(1) and articles 10(1) and 10(2), both of Decree-Law No. 10/2011 of 20 January, which approved the Legal Framework for Tax Arbitration, and articles 1 and 2 of Ordinance No. 112-A/2011 of 22 March, requested the establishment of an arbitral tribunal for the declaration of illegality and annulment of the aforementioned additional assessment acts, as well as the compensatory interest relating thereto.

  2. The request for establishment of the arbitral tribunal was accepted by the President of CAAD and automatically notified to the Tax and Customs Authority on 27.09.2017.

  3. In accordance with articles 5(2)(a), 6(1) and 11(1) of the Legal Framework for Tax Arbitration (RJAT), the Ethics Council of this Administrative Arbitration Center (CAAD) designated as a collective arbitral tribunal Councillor Dr. José Poças Falcão, Professor Doctor Jónatas Machado, and Dr. José Rodrigo de Castro, whose acceptance was confirmed on 15.11.2017.

  4. The parties were duly notified of this designation, to which they did not object in accordance with the combined provisions of articles 11(1)(b) and (c) and 8 of the RJAT and articles 6 and 7 of the Code of Ethics of CAAD.

  5. By virtue of the provision in article 11(1)(c) and 11(8) of the RJAT, in accordance with the communication of the President of the Ethics Council of CAAD, the Arbitral Tribunal was constituted on 06.12.2017.

Description of Facts

  1. In the request for arbitral pronouncement, A… and his wife, B… (hereinafter referred to as the Applicants), requested the declaration of illegality and annulment of the assessment acts 2017…, of 24 May, 2017…, of 30 May, 2017…, of 26 May and 2017…, of 21 June, as well as the compensatory interest relating thereto.

  2. The Applicants were subject to an inspection action regarding PIT for the years 2012 and 2013, in accordance with service orders OI2015… and OI2016…, which are on file.

  3. In the view of the Inspection Services of the Tax Authority, deposits were made in the bank accounts of the Appellants, without the origin and liability to taxation being demonstrated, for which reason it was understood that the conditions were met for such income to be qualified as unjustified asset increases and for the determination of taxable income for PIT for the years 2012 and 2013 to be carried out through the application of indirect assessment methods.

  4. The Tax Authority notified the Appellants on 19 February 2015, requesting that proof of the source of income underlying the increase in income be provided.

  5. On 18 March 2015, the Appellants sent copies of the bank statements of account C…, the then designated D… and E…, in addition to the balances of savings accounts.

  6. The Inspection Services of the Tax Authority concluded that the amounts in the current and fixed-term accounts of C…, D…, E… and the Public Debt and Treasury Management Agency are properly documented for the years 2012 and 2013.

  7. Regarding account F…, the Tax Inspection Services understood that there was a need to investigate the movements, and requested the Appellants to justify the origin of the numerous credit entries in the years in question, which was to be accompanied by supporting documents.

  8. The Appellants, by communication of 30 October 2015, justified the movements with inventories and tangible fixed assets arising from the exercise of a grocery business, which had been exercised by the Appellant until the end of 2009, further stating that over the years, deposits were made in the aforementioned F… account relating to the salaries of the Appellants' son and daughter-in-law.

  9. The Tax Inspection Services understood that acceptance of the reasons invoked would have to be based on supporting documents, namely invoices and receipts relating to the operations in question.

  10. The Appellants were unable to provide all the documents requested by the Inspection Services, for which reason corrections were made to the taxable income for PIT for the years 2012 and 2013, in the total amount of € 428,588.93 (four hundred twenty-eight thousand five hundred eighty-eight euros and ninety-three cents). As a consequence of the aforementioned corrections, the PIT assessment for the years in question was also corrected, resulting in a total amount of tax to be paid of € 257,153.36 (two hundred fifty-seven thousand one hundred fifty-three euros and thirty-six cents).

  11. The TA, pursuant to article 17 of the RJAT, filed on 29.01.2018 the administrative file and its Response to the Applicant's request for arbitral pronouncement, wherein it sustains the validity of the exceptions of material incompetence of CAAD in the field of application of indirect methods, res judicata and impropriety of the procedural means, or alternatively, the lack of merit of the arbitral petition as unproven, with the consequent discharge of the Respondent from all claims, all with the appropriate legal consequences.

Arguments of the Parties

  1. The arguments and counter-arguments put forward by the parties fundamentally concern the legitimacy of indirect assessment and the competence of the CAAD arbitral tribunal to hear challenges to such assessment.

  2. To substantiate its position, the Applicant alleges that the contested assessments [and presents extensive arguments regarding the burden of proof, the effective date of Law No. 55-A/2012, and the requirement that documentary evidence be from after the law's entry into force].

  3. To the contrary, the argument developed by the Respondent rests on the following topics [and presents extensive arguments regarding material incompetence of the arbitral tribunal, res judicata, the binding nature of the decision of the Lisbon Tax Court, and the impropriety of the arbitral remedy].

Arbitral Meeting Pursuant to Article 18 of the RJAT

  1. As it was considered unnecessary, the meeting provided for in article 18 of the RJAT was dispensed with.

Final Submissions

  1. In their submissions, the Applicants did not respond to the preliminary exceptions raised regarding material incompetence of the CAAD arbitral tribunal, res judicata and impropriety of the procedural means adopted, and reiterated the legal grounds presented in the initial petition.

  2. The Applicants stated that they had submitted all the documentation they had available, and that the remaining supporting documents requested by the Respondent concern facts all of which occurred before the date of entry into force of the law in 2012, reiterating that their non-presentation cannot result in indirect determination of taxable income and additional assessment of tax, as the TA contends.

PRELIMINARY ISSUES

  1. The preliminary exceptions of material incompetence of the CAAD arbitral tribunal, res judicata and impropriety of the procedural means adopted by the Applicants were invoked, a ruling on which prevents immediate consideration of the merits of the case.

  2. The Arbitral Tribunal is regularly constituted (articles 5(1) and (3)(a), 6(2)(a) and 11 of the RJAT) and is materially competent (articles 2(1)(a) of the RJAT).

  3. The parties have legal standing and capacity and are duly represented.

REASONING

Facts Established as Proven

  1. Based on the documents submitted and without prejudice to other accessory facts related to them on file, the following facts relevant to the decision in the present case are established as proven:

  • In 2012 the Applicants declared PIT income in the amount of € 10,145.25. (PA)

  • In 2013 the Applicants declared PIT income in the amount of € 12,836.36. (PA)

  • The Applicants were subject to an inspection action regarding PIT for the years 2012 and 2013, in accordance with service orders OI2015… and OI2016…. (PA 2)

  • According to the information in the model 39 declaration, it was found that various amounts were credited to the Applicants' bank accounts in 2012 and 2013 in the form of interest and other income, in some cases paid by non-resident entities, respectively in the total amounts of € 127,930.14 and € 223,165.42. (PA 8 and 19)

  • The Applicants were notified of the additional PIT assessments for the years 2012 (2017…, of 24 May, 2017…, of 30 May) and 2013 (2017…, of 26 May and 2017…, of 21 June), resulting from the application of indirect methods, in the amounts of, respectively, € 126,527.54 (one hundred twenty-six thousand five hundred twenty-seven euros and fifty-four cents) and € 168,682.78 (one hundred sixty-eight thousand six hundred eighty-two euros and seventy-eight cents), totalling € 295,210.32 (two hundred ninety-five thousand two hundred ten euros and thirty-two cents), on the grounds that unjustified asset increases exist. (PA 1)

Facts Not Established as Proven

  1. With relevance to the decision on the merits, there are no alleged facts that should be considered as not proven.

Motivation

  1. Regarding the facts, the Tribunal need not pronounce on everything alleged by the parties, but rather may select the facts that matter for the decision and distinguish established facts from unestablished ones (see article 123(2) of the Code of Procedure and Tax Process and article 607(3) of the Code of Civil Procedure, applicable ex vi article 29(1)(a) and (e) of the RJAT).

  2. The facts pertinent to the judgment of the case are selected and delineated in function of their legal relevance, which is established in light of the various plausible solutions to the questions at issue in the dispute (see article 596(1) of the Code of Civil Procedure, ex vi article 29(1)(e) of the RJAT).

  3. Accordingly, having regard to the positions assumed by the parties and the documentary evidence submitted, the aforementioned facts were established as proven, as relevant to the decision.

Issues to be Decided

Preliminary Exceptions

  1. The TA in its Response of 29 January 2018 invokes, by way of exception, the material incompetence of CAAD in the matter of application of indirect methods.

  2. In it the Respondent recalls that the assessment acts now being challenged are based on an inspection action determined by OI2015… and OI2016…, which led to the application of indirect methods.

  3. And that this action by the TA resulted from the absence of proof regarding all the bank movements in F…, for the years 2012 and 2013, as required by article 89-A(3) of the General Tax Law (LGT).

  4. The TA further states that the Applicants intend through the present arbitral challenge to impugn the PIT assessment acts resulting from the application of indirect methods for the aforementioned years 2012 and 2013.

  5. It further emphasizes that it is admitted in article 10 of the arbitral petition that they timely filed the appeal provided for in article 146-B of the Code of Tax Procedure and Process in the Lisbon Tax Court, Case No. …/16… BELRS, challenging the application of indirect methods regarding the same matter now under analysis, an appeal which was not successful, as shown in the annex to the administrative file submitted by the TA to the present proceedings.

  6. The Respondent notes that as the Applicants now seek to remedy the insufficient proof evident in the proceedings before the Lisbon Tax Court, whose decision has already become final, it believes that the Applicants' claim cannot be considered in the present arbitral proceedings.

  7. And it bases its thesis on the provisions of article 2(1) of the RJAT, concerning the competence of arbitral tribunals and applicable law, also citing the decision in Arbitral Case No. 17/2012-T, of 14 May, which characterized the present exception as "incompetence of the arbitral tribunal" in the following terms:

"In fact, the lack of binding effect on the Tax and Customs Authority of a decision by the arbitral tribunal translates into the immediate impossibility of the subjective efficacy of a judgment which, if it were rendered by this tribunal in the excluded matters, would produce no effects on the party obligated to execute it, thus constituting lack of jurisdiction, which is delimited by reference to the subject matter and therefore constitutes material incompetence of this tribunal.

It is thus beyond question for us that the lack of jurisdiction of the tribunal to resolve the dispute does indeed configure the preliminary exception of incompetence and not any other, and, given the arbitral nature of the tribunal, an integrated reading must be made of article 2(1) of the RJAT, with article 4(1) thereof, and also with the aforementioned article 2 of the Binding Ordinance above transcribed."

  1. On the other hand, the Respondent makes a point of also referring to the decision rendered in Arbitral Case No. 70/2012-T, of 31 October 2012 (wherein the present exception was characterized as "an unnamed preliminary exception of the lack of binding effect of the ATA"), in the following terms cited from it:

"We thus understand that the respondent is not bound by the jurisdiction of the CAA as to this matter. We consider this to be an unnamed preliminary exception and not material incompetence since the ordinance did not revoke the norm of competence attributed to the arbitral tribunal by Decree-Law No. 10/2011 of 20 January. The norm of this decree-law attributing competence remains in force. What exists is the absence of binding effect of the ATA as regards the type of acts in question. In any event, the consequence is the same: the dismissal of the arbitral proceedings."

  1. The Respondent further finds it relevant to cite the commentary of Councillor Jorge Lopes de Sousa on the RJAT, published in the "Guide to Tax Arbitration," citing what is said by the Councillor at pages 138 and 139:

"Although subparagraph (b) of article 2(1) of the RJAT includes in the competence of arbitral tribunals the declaration of illegality of acts of determination of taxable income and determination of taxable income in which indirect methods were used, the Tax Administration excluded this possibility by expressly excluding from its binding commitment to such tribunals 'claims relating to acts of determination of taxable income and acts of determination of tax, both by indirect methods, including the decision of the revision procedure' – subparagraph (b) of article 2 of Ordinance No. 112-A/2011 of 22 March."

  1. Whence, the Respondent concludes that it clearly and unquestionably follows that the TA is not bound by arbitral jurisdiction regarding acts of determination of taxable income by indirect methods, and likewise regarding the decision of the revision procedure, and that therefore this leads to the dismissal of the proceedings.

  2. On the other hand, the Respondent considers this to be a case of res judicata material, in accordance with the judgment of 30-4-2017, in case no. …/16… BELRS, Lisbon Tax Court, which is indeed competent to consider the matter in question and which decided as follows:

"Having analyzed the asset increases verified and the amounts declared by the Appellants in PIT, an obvious and manifestly disproportionate divergence and absolute discrepancy between these values clearly results, which in the present case leads to the verification of the objective conditions set forth in article 87(1)(f) of the LGT"….

Further stating in said judgment:

"Notwithstanding the burden of proof incumbent upon it, it was not established in the file that the deposits in the F… account originated from the sale of goods from the inventory and tangible fixed assets that were attributed to the Appellant following the cessation of the grocery business exercised by her until 2009".

Whence the conclusion of the same judgment:

"Therefore, the decision to indirectly assess the taxable income rendered in the present proceedings does not suffer from any illegality and must remain in the legal order, in which terms it must, naturally, find the present appeal to be without merit".

  1. And the Respondent comes to reinforce the impossibility of the present Arbitral Tribunal, which is not an appellate tribunal from the decision taken by that one, which it could not even be, taking cognizance of the merits of the present action, under pain of risking contradicting what was previously decided by another tribunal.

  2. And it is in these terms that the Respondent invokes the preliminary exception of material res judicata referred to in article 577(i) of the Code of Civil Procedure, which determines the dismissal of the proceedings in accordance with article 278(e) of the same statute.

  3. It happens that the Applicants in the present Arbitral Appeal acknowledge having filed a Judicial Appeal in the Lisbon Tax Court, which was found to be without merit by judgment of 30 April 2017, due to partial proof (made only until 2009) regarding bank movements in account F… and also acknowledge that, in fact, they did not make, before the TA, the proof that was required of them by article 89-A(3) of the LGT, which thus determines, where the situations provided for in article 87(1)(f) also of the LGT are verified, as was the case.

  4. What the Applicants now intend is to present clarifications and attach the documents necessary to make the proof that they then did not make and which led to the application of indirect methods to determine taxable income for 2012 and 2013, as they are now in a position to do so.

  5. And, therefore, the Applicants submitted with their initial petition a set of 12 annexes, with the alleged proof of the bank movements in their F… account, up to and including the years 2012 and 2013.

  6. On the other hand, they contest that they are legally required to prove the origin of the income in question, arguing, according to them, that such requirement, as regards current or fixed-term deposit accounts, became legally possible only as of 1 January 2012, the date of entry into force of Law No. 55-A/2012 of 29 October, when the required supporting documents were intended to provide proof prior to 2012.

  7. Regarding the arguments just mentioned in the preceding paragraphs, the TA responds that with respect to the new documents they seek to attach in the set of 12 annexes mentioned, this is not legally possible, both because this arbitral tribunal is not competent to know of the illegality of the application of indirect methods, as already demonstrated, and because it does not recognize the documents as having sufficient evidentiary value.

  8. On the other hand, the Respondent counters that the Applicants are not correct in asserting the legal impossibility of requiring proof documents prior to 2012, based on the norm of article 89-A(1)(d) of the LGT, which imposes the burden of proof on the taxpayer, because of the entry into force on 1-1-2012 of Law 55-A/2012 of 29 October, which is only valid regarding financial institutions resident in a country, territory or region subject to a clearly more favorable tax regime – which is not the case with F….

  9. The Respondent, in reinforcement of its thesis, again cites some teachings of Councillor Jorge Lopes de Sousa, in Annotated Code of Tax Procedure and Process, Áreas Editora, Volume II, article 146-B, pages 570-571, according to which:

"Thus, these decisions of indirect assessment of taxable income assume the nature of separable acts for purposes of tax-related challenge, although they are part of a procedure for assessment of a tax. The attribution of this nature of separable acts implies that the illegalities from which such acts suffer may only be invoked in their own challenge procedure, and cannot be invoked in the challenge to the act of assessment of the tax that comes to be made based on the act of assessment of taxable income by indirect methods referred to in article 89-A of the LGT. In fact, this separation of the scope of tax-related challenges between the separable act and the final act is precisely the objective pursued, with the attribution to the first of this nature of separable act being justified because the entity performing the act is different."

  1. Thus and therefore, alleged illegalities arising from the determination of taxable income by application of indirect methods cannot be invoked in the challenge to the assessment acts that follow from it.

  2. Whence, the Respondent concludes that the preliminary exception of the impropriety of the procedural means used by the Applicants should not be found to have merit, for which reason the Respondent should be dismissed from the proceedings.

Merits

  1. For all the above and in light of the arguments expounded by the parties, in particular by the Respondent, supported by the doctrine and case law cited, it seems that this Tribunal is left in no doubt that:

  • An integrated reading of article 2(1) of the RJAT, with article 4(1) thereof, and also with aforementioned article 2(b) of Ordinance No. 112-A/2011 of 22 March, concerning the Binding Commitment of the Tax and Customs Authority, allows the conclusion, without room for doubt, that this Arbitral Tribunal is materially incompetent by reason of the lack of binding effect of the TA to consider the merits of the case and, consequently, the additionally offered documents;

  • Also, in light of the immediate impossibility of the subjective efficacy of a judgment which, if it were rendered by this tribunal in the excluded matters, would produce no effects on the party obligated to execute it, thus constituting lack of jurisdiction, which is delimited by reference to subject matter and therefore constitutes material incompetence of this tribunal.

  • But, even if one were to consider that this tribunal does not face a material incompetence, one would always be faced with an unnamed preliminary exception that, by itself, prevents this Arbitral Tribunal from considering the merits or demerits of the case;

  • Where it concerns the consideration of additional proof for purposes of determining taxable income that was determined by indirect methods, and thus concerning separable acts for purposes of tax-related challenge, these cannot be invoked in the present arbitral challenge and therefore this Arbitral Tribunal cannot know of it;

  • Finally, this Tribunal also cannot consider the merits of the case, so as not to place itself in a position of contradiction with the Lisbon Tax Court, where the legality of the determination by indirect methods was considered and decided unfavorably to the Applicants.

DECISION

For these reasons, this Arbitral Tribunal decides:

  • To find the invoked unnamed preliminary exception of impropriety or impropriety of the procedural means used by the Applicants to have merit;

  • To declare itself materially incompetent to know of the merits of the case and, as a consequence, to dismiss the Respondent from the proceedings, in accordance with article 278(e) of the Code of Civil Procedure;

  • To dismiss the Respondent from the proceedings;

  • To find the Applicants' Appeal to be without merit, for the reasons extensively expressed above;

  • To maintain in the legal order the additional PIT assessment acts for the years 2012 (2017…, of 24 May, 2017…, of 30 May) and 2013 (2017…, of 26 May and 2017…, of 21 June), in the amounts of, respectively, € 126,527.54 (one hundred twenty-six thousand five hundred twenty-seven euros and fifty-four cents) and € 168,682.78 (one hundred sixty-eight thousand six hundred eighty-two euros and seventy-eight cents), totalling € 295,210.32 (two hundred ninety-five thousand two hundred ten euros and thirty-two cents).

Value of the Proceeding

The value of the proceeding is set at € 295,210.32 (two hundred ninety-five thousand two hundred ten euros and thirty-two cents) in accordance with article 306(1) of the Code of Civil Procedure and article 97-A(1)(a) of the Code of Procedure and Tax Process, applicable pursuant to article 29(1)(a) and (b) of the RJAT and article 3(2) of the Regulation of Costs in Tax Arbitration Proceedings.

Costs

The amount of the arbitration fee charged to the Applicants is set at € 5,202.00 in accordance with article 12(2) and 22(4) of the RJAT and article 4(4) of the Regulation of Costs in Tax Arbitration Proceedings and Table I annexed thereto.

Frequently Asked Questions

Automatically Created

What are unjustified wealth increases (acréscimos patrimoniais não justificados) for IRS purposes in Portugal?
Unjustified wealth increases (acréscimos patrimoniais não justificados) are increments in a taxpayer's assets or decreases in liabilities that cannot be justified by declared income or other legitimate sources. Under Article 87 of the IRS Code, when taxpayers make bank deposits, acquire assets, or reduce debts without demonstrating the taxable or non-taxable origin of the funds, the Tax Authority presumes these represent undeclared income subject to IRS. The taxpayer bears the burden of proving the legitimate origin of these wealth increases. If adequate documentation is not provided during inspection, the amounts are added to taxable income and taxed at the highest marginal rate applicable to the taxpayer's situation, often resulting in significant additional tax assessments.
Can the CAAD tax arbitration tribunal review additional IRS assessments based on indirect assessment methods?
The competence of CAAD arbitration tribunals to review assessments based on indirect methods has been a contested issue in Portuguese tax law. Article 2(1)(a) of the RJAT grants CAAD jurisdiction over the legality of tax acts, but Article 2(2)(c) excludes acts involving the application of indirect methods of assessment 'as such' (enquanto tal). This creates interpretative challenges: tribunals can review formal and procedural legality aspects but face limitations on reviewing the substantive application of indirect methods. The distinction between reviewing 'separable acts' (atos destacáveis) - preliminary decisions that can be independently challenged - and the core indirect assessment determination itself is crucial. Some decisions have found material incompetence when the challenge fundamentally questions the indirect method application rather than discrete procedural violations.
What happens when bank deposits cannot be justified by the taxpayer during a tax inspection in Portugal?
When taxpayers cannot justify bank deposits during a tax inspection in Portugal, the Tax Authority typically initiates procedures under Article 89-A of the IRS Code for unjustified wealth increases. First, the Authority notifies the taxpayer to provide documentation proving the origin and nature of the deposits within a specified timeframe. If the taxpayer fails to provide adequate supporting documents (invoices, receipts, contracts, loan agreements, gift declarations), the Tax Authority may classify the deposits as taxable income. This triggers the application of indirect assessment methods, adding the unjustified amounts to the taxpayer's declared income. The Authority then issues additional IRS assessments, often with penalties and interest. The taxpayer can challenge these assessments through administrative complaints, judicial appeals to Tax Courts, or arbitration at CAAD, though jurisdictional limitations may apply depending on whether the challenge concerns procedural issues or the substantive application of indirect methods.
How does the concept of material incompetence (incompetência material) affect tax arbitration proceedings at CAAD?
Material incompetence (incompetência material) is a fundamental jurisdictional defect that prevents a tribunal from adjudicating certain matters. In tax arbitration at CAAD, Article 2(2) of the RJAT expressly excludes specific categories from arbitral jurisdiction, including acts involving criminal offenses, the application of general anti-abuse rules, and controversially, 'the application of indirect methods of assessment as such.' When the Tax Authority raises material incompetence as a preliminary exception, the arbitral tribunal must determine whether the challenged act falls within its statutory jurisdiction. If the core dispute concerns the substantive determination of taxable income through indirect methods rather than separable procedural acts, the tribunal may lack competence and must decline jurisdiction, dismissing the case without examining the merits. This exception protects jurisdictional boundaries between arbitration and judicial courts, as certain complex assessment determinations are reserved for specialized Tax Courts with exclusive competence.
What is the role of 'atos destacáveis' (separable acts) in challenging additional IRS tax assessments in Portugal?
The concept of 'atos destacáveis' (separable acts) is critical in Portuguese tax procedure for determining which preliminary or ancillary decisions can be independently challenged before final assessment. Separable acts are intermediate administrative decisions that produce autonomous legal effects and can be contested separately from the main tax assessment, such as decisions to apply indirect methods, refusals to consider documentation, or procedural determinations. In the context of unjustified wealth increases, taxpayers may argue that certain decisions during the inspection process - such as rejecting submitted documentation or determining that indirect methods should be applied - constitute separable acts subject to immediate challenge. However, Portuguese jurisprudence and CAAD practice have increasingly restricted this concept, particularly regarding indirect methods. Courts often hold that decisions intrinsically linked to the final assessment calculation are not truly separable and can only be challenged when contesting the final additional assessment itself, not independently through arbitration if the tribunal lacks material competence over the indirect method application.
