Process: 89/2019-T

Date: June 14, 2019

Tax Type: IRC IVA

Source: Original CAAD Decision

Summary

CAAD Process 89/2019-T examines the legality of IRC (Corporate Income Tax) and IVA (VAT) assessments for 2014 totaling €25,970.19, where the Tax Authority applied indirect assessment methods (métodos indiretos) following an inspection that revealed accounting irregularities and successive tax losses. The claimant challenged the assessments, arguing that prerequisites for indirect methods were not met and that losses resulted from legitimate deficitary operations of the commercial establishment, not income omission. The taxpayer emphasized that transferring operations for €4,200/year demonstrated genuine poor performance rather than hidden income. The Tax Authority defended the indirect assessment under Articles 87(b)(e) and 88(a) of the LGT, and Article 57 of the CIRC, citing accounting irregularities, credit balances in cash accounts, and unjustified successive losses from 2012-2014. Key legal issues include: (1) whether prerequisites for applying indirect methods existed, (2) whether CAAD has jurisdiction over indirect method disputes, and (3) whether the quantification methodology was appropriate. The case illustrates the burden on taxpayers to justify successive losses and maintain proper accounting records. It demonstrates that tax authorities must prove impossibility of direct assessment before resorting to indirect methods, which can only be applied exceptionally when direct quantification is impossible due to accounting deficiencies, omissions, or irregularities that prevent exact determination of taxable income.

ARBITRAL DECISION

REPORT

A – PARTIES

A..., LDA., holder of tax identification number..., with registered office at Rua ..., no...., ...-... ..., hereinafter designated as Claimant or Taxpayer.

TAX AND CUSTOMS AUTHORITY, hereinafter designated as Respondent or AT.

On 12-02-2019, the request for establishment of the Arbitral Tribunal was accepted by His Excellency the President of CAAD, and the Tax and Customs Authority was automatically notified, as recorded in the respective minutes.

The Claimant did not proceed to appoint an arbitrator, therefore, pursuant to the provisions of Article 6, paragraph 1 and Article 11, paragraph 1, letter b) of Decree-Law no. 10/2011, of 20 January, as amended by Article 228 of Law no. 66-B/2012, of 31 December, the Ethics Council appointed as arbitrator His Excellency Dr. Paulo Ferreira Alves, who communicated his acceptance, as legally provided.

On 02-04-2019 the parties were duly notified of such appointment, and did not manifest the intention to refuse it, in accordance with Article 11, paragraph 1, letters a) and b), of the RJAT and Articles 6 and 7 of the Code of Ethics.

Thus, in compliance with the provision of Article 11, paragraph 1, letter c) of Decree-Law no. 10/2011, of 20 January, as amended by Article 228 of Law no. 66-B/2012, of 31 December, the Singular Arbitral Tribunal was duly established on 25-03-2019.

Both parties agreed to dispense with the meeting provided for in Article 18 of the RJAT.

Responses to the exceptions raised and successive written submissions were presented.

The Arbitral Tribunal was duly established on 23-04-2019 and has material jurisdiction, in accordance with Articles 2, paragraph 1, letter a), and 30, paragraph 1, of Decree-Law no. 10/2011, of 20 January.

The parties have legal personality and capacity, are legitimate and are legally represented (Articles 4 and 10, paragraph 2, of the same decree and Article 1 of Ordinance no. 112-A/2011, of 22 March).

The proceeding has no defects that would invalidate it.

B – CLAIM

1. The Claimant petitions for a declaration of partial illegality of the tax assessment act for Corporate Income Tax, referring to the year 2014, no. 2018..., of 15.10.2018, and for Value Added Tax, referring to the year 2014, nos. 2018..., 2018..., 2018..., 2018..., 2018..., 2018..., 2018... and 2018..., all dated 13.10.2018, in the total amount of €25,970.19 (twenty-five thousand, nine hundred and seventy euros and nineteen cents).

C – GROUNDS FOR CLAIM

2. The Claimant alleged in summary, in order to substantiate its request for an arbitral ruling declaring the tax assessment acts illegal, the following:

2.1. The prerequisites for the application of indirect methods are not met.

2.2. It vehemently refutes the alleged omission of income that never occurred.

2.3. The occurrence of successive losses stems solely from the unavoidable deficitiary operation of the commercial establishment in question, and evidence thereof results from the fact mentioned in the Inspection Report in its section II.3.2, at page 7, where it states that "At the beginning of 2017, there was a transfer of operation of the establishment in favor of taxpayer B..., TIN ..., initially paying the monthly amount of €900.00 and in late 2007, it was reduced to €350.00."

2.4. It argues that there was a manifest erroneous quantification of the taxable income proposed through the use of indirect assessment, that is, if A. had withdrawn from the operation it was carrying out of the establishment in question an annual accounting result in the order of €80,000.00 (which is, roughly speaking, the taxable income proposed using indirect assessment, see pages 3 and 6 of the Report), the decision to transfer the operation with a consideration of €4,200.00/year could not fail to be configured as an effective decision that bordered on harmful management, because it was forgoing income exceeding €75,000.00/year.

2.5. The true reasons for the deficitiary operation and the successive incurrence of relevant tax losses stem from everything that was clarified in the letter dated 15 March 2018 and which is part of Annex 6 of the Report and is at pages 12 to 14 (ab initio) of that document and not from the implausible thesis of income omission. This simple exercise clearly demonstrates the inadequacy of the result of the inspection procedure that was the basis for the correction proposals and the tax assessment acts that are based thereon and are being challenged here.

2.6. We have already raised and here renew that we consider that the prerequisites for the application of indirect methods are not met, in this case, through the use of presumptions or estimates, intended for the determination of VAT; as we also consider that the use of the application of indirect methods for the determination of taxable income in Corporate Income Tax is likewise not legitimized.

2.7. The power that the Administration has to alter the declared values can only be used in exceptional situations, namely when it is entirely impossible to prove and quantify directly and exactly the elements necessary for their determination.

2.8. It concludes by invoking that the entire inspection action is tainted at its foundation, either because the prerequisites for the applicability of indirect methods do not exist or because of the inadequacy of the criteria used to determine the taxable base or the presumed tax; therefore, the proposed corrections could not fail to be reconsidered under penalty of the subsequent tax assessment acts coming to suffer from gross illegality, which is now evident and consequently being challenged here.

D – RESPONDENT'S RESPONSE

3. The Respondent, duly notified for this purpose, timely presented its response, alleging in brief summary, the following:

3.1. According to the facts established in the inspection report and subject to review in the context of the revision procedure referred to in Article 91 of the LGT, irregularities were found in the Claimant's accounting that prevented the determination and quantification of the taxable base through direct assessment, and for that reason the recourse to indirect assessment was justified, in accordance with Article 57 of the CIRC, as well as Articles 87, letters b) and e), and Article 88, letter a), all of the LGT.

3.2. In the context of the application of indirect methods, questions regarding the prerequisites are essentially justified through the sufficiency or insufficiency of the existing elements to determine the taxable base with exactness.

3.3. Now, from the in-depth analysis of the Claimant's accounting, regarding the year 2014, it was proven that the accounting and the values contained in the tax returns filed do not reflect the true tax result obtained by the taxpayer, and it is not possible to determine directly and exactly the taxable base/Tax (Corporate Income Tax and VAT).

3.4. Faced with the occurrence of successive tax losses, it was incumbent upon the Claimant to demonstrate the corresponding justifying reasons for their existence, which, in accordance with what is stated in the Tax Inspection Report, corroborated by the expert of the Tax Authority, was not demonstrated.

3.5. Being that personnel costs have assumed practically constant values between 2012 and 2014, with the staff structure remaining unchanged, the existence of expenses for indemnities are not reflected in the year under analysis, the value of depreciation/amortization, from 2011 to 2014 relating to investments, has decreased, and the supplier account credit balances were regularized as a counterpart to the partner accounts.

3.6. In addition to the Claimant not having proceeded to justify the successive tax losses in the years 2012, 2013 and 2014, it became evident that there were omissions, errors and inaccuracies in the accounting, namely the persistence of the credit balance in the cash account, with its cancellation carried out on the basis of an internal document, as well as non-compliance with the provision of Article 63-C of the LGT, since not all movements related to capital contributions or other forms of loans passed through the respective bank account.

3.7. The determination of the taxable base being justified by the application of indirect assessment methods, the Tax Inspection Services proceeded to determine the taxable base and tax, with the sales volume having been presumed through the application of the R18 ratio (average of the Claimant's operational unit).

3.8. On the other hand, from the analysis of the payroll statement contained in the database of the respondent entity, it appears that in 2010 there were 4 employees performing functions in the company and, from that year onward, there were 3 employees at least until 2014, being that in 2010, the Claimant, with 4 employees, had a total sales volume of €102,884.08, with a sales volume per employee of €25,721.00, and for the year 2011, with 3 employees, with a total sales volume of €95,282.39, it is €31,760.00 for each employee, and in the year 2014 that value became €12,048.00.

3.9. As to the justification that dismissal indemnities were paid and substantial initial investment versus depreciation/amortization, it should be noted that this justification cannot be accepted, since personnel costs have assumed practically constant values since 2012 to 2014, and, as already mentioned, the staff structure remained unchanged, and it is certain that, if there was any expense for indemnities, it would already have been reflected before the year 2010.

3.10. As for investments and depreciation/amortization, from 2011 to 2014, the values have decreased, which also cannot justify the occurrence of losses; furthermore, the allegation that losses are the reflection of a deficitiary activity and not of omission of income/revenue, has no support, since, from the beginning of the activity, the Claimant has always reported losses, in this case between the years 2007 and 2017, presenting an extremely high accumulated value, and being the ultimate purpose of any company profit, it is legitimate to question whether for ten years the partners had been financing a deficitiary operation.

3.11. Regarding the maintenance of credit balances in the cash account during the entire year 2014, which violates all accounting rules inherent in SNC (Portuguese Accounting Standards), with the credit balance of the account having been cancelled with an internal document, in the amount of €6,171.73, whose counterpart was the partner loan account, without any document attesting to the financial flow, which is manifestly indicative that the accounting did not reflect all its operations.

3.12. In fact, the partner account cannot be transformed into a financial means account, once again making clear that the accounting of operations in partner accounts has underlying failures/lack of entry of financial flows into the Claimant, by omission of the accounting of service provisions, causing the existence of credit balances in the cash account in all months of the year in question.

3.13. In the interest of truth, and this obligation not having been fulfilled by the company, the situations described above show that the accounting does not reflect all movements of each period, evidencing inaccuracies and omissions in its execution, which resulted in the existence of credit cash balances, and evidences the omission of service provision.

3.14. In summary, given the anomalies, omissions and insufficiencies found in the Claimant's accounting, there was no other course for the Respondent entity but to resort to such presumptions or estimates, to calculate and determine the missing tax, having proceeded to the respective alteration, in the terms explained in the inspection report, so as to determine the taxable income of the Claimant's actual activity in the 2014 fiscal year.

E – FACTUAL FOUNDATION

4. With relevance for the appreciation and decision of the issues raised, preliminary and substantive, the following facts are established as proven:

5. An external inspection action was carried out on the Claimant, for the 2014 fiscal year and of partial scope in the context of Corporate Income Tax and VAT, in accordance with Service Order no. OI2017..., issued by dispatch of 01.03.2017.

6. From that inspection action, it is evident from the tax inspection report that the AT resorted to the application of indirect assessment methods, as demonstrated by the content of the notification made to the Claimant:

"

7. The Claimant on 12.06.2018 submitted a request for official review of the Inspection Report, in accordance with the terms and for the purposes set forth in Article 91 of the LGT.

F – UNPROVEN FACTS

9. Of the facts with interest for the decision of the case, subject to concrete analysis, there are no other facts with relevance for the appreciation of the substantive merits of the case that have not been proven.

G – QUESTIONS FOR DECISION

10. Given the position of the parties, assumed in the arguments presented, the following constitute the central questions to be decided, which must therefore be appreciated and decided:

a. Those alleged by the Claimant:

(i) Declaration of partial illegality of the tax assessment act in the context of Corporate Income Tax and VAT

(ii) Condemnation to payment of compensatory interest.

b. Those alleged by the Respondent:

(i) Exception for lack of material jurisdiction of the arbitral tribunal regarding the matter of application of indirect methods;

(ii) Exception of illegal cumulation of claims;

(iii) Exception of untimeliness of the claim.

G – EXCEPTION FOR LACK OF JURISDICTION OF THE ARBITRAL TRIBUNAL RATIONE MATERIAE

11. The Respondent raises the lack of jurisdiction of the Arbitral Tribunal ratione materiae, specifically to appreciate and decide the claim in the dispute sub judice, in accordance with Articles 2, paragraph 1, letter a), and 4, paragraph 1, both of the RJAT, and Articles 1 and 2, letter a), both of Ordinance no. 112-A/2011, which constitutes a preliminary exception preventing the knowledge of the substantive merits of the case, in accordance with Article 576, paragraphs 1 and 2 of the CPC, via Article 2, letter e) of the CPPT and Article 29, paragraph 1, letters a) and e) of the RJAT, which prevents the knowledge of the claim and the dismissal of the AT from the instance in accordance with Articles 576, paragraph 2 and 577, letter a) of the CPC, via Article 29, paragraph 1, letters a) and e) of the RJAT.

12. It is incumbent upon the Tribunal to first address the exception raised, in accordance with Article 608, paragraph 1 of the CPC "(...) the judgment shall first address the procedural questions that may result in the dismissal of the instance, according to the order imposed by their logical precedence.".

13. Thus, we shall immediately proceed to its consideration.

14. The Arbitral Tribunal, it should be noted, has jurisdiction to decide on its own jurisdiction. This is the "principle of the arbitral tribunal's competence to determine its competence" (in its positive aspect), long recognized as a rule in matters of arbitration. Unlike the institutionalized arbitration center, which has no interference in the decisions of the cases submitted to each Arbitral Tribunal.

15. Article 13 of the ETAF provides, as regards knowledge of jurisdiction and the scope of administrative jurisdiction, that "The scope of administrative jurisdiction and the jurisdiction of administrative courts in any of their forms are of public order and their knowledge precedes that of any other matter".

16. In these terms, the jurisdiction of the Arbitral Tribunal comprises the appreciation of the claims listed in Article 2 of Decree-Law no. 10/2011, of 20 January (RJAT).

17. The AT, in its response, raised the preliminary question of the jurisdiction of the Arbitral Tribunal established in CAAD, to appreciate the issues raised in the present case, since the disputed claim concerns the application of indirect methods, which, in its view, this matter is not covered by the jurisdiction of Arbitral Tribunals.

18. The Claimant, duly notified, came to pronounce itself on said exception requesting its dismissal, arguing that assessment acts subsequent to an act of determination of the taxable base through the application of indirect methods, in which the illegality thereof is invoked as the ground for the claim, it is for the Arbitral Tribunal to judge it as competent.

19. Now, the jurisdiction of Arbitral Tribunals, in particular the jurisdiction of the Arbitral Tribunal functioning in CAAD is limited in the terms to which the Tax Authority bound itself to that jurisdiction, specified in Ordinance no. 112-A/2011, of 22 March. In this way, Article 4 of the RJAT establishes that "the binding of the tax administration to the jurisdiction of tribunals established in accordance with the provisions of this law, depends on an ordinance of the Government members responsible for the areas of finance and justice, which establishes, in particular, the type and maximum value of the disputes covered", wherein the binding to arbitral jurisdiction by the services - DGCI and DGAIEC - entities merged in the current Tax and Customs Authority, with effect as of 1 January 2012, is postulated.

20. Therefore, the jurisdiction of Arbitral Tribunals functioning in CAAD depends essentially on the terms of this binding, because, even if one is faced with a situation that could be framed in Article 2 of the RJAT, if it is not covered by said binding, the possibility of the dispute being jurisdictionally decided by this Arbitral Tribunal will be ruled out.

21. In turn, Ordinance no. 112-A/2011 of 22 March, in its Article 2, states that: "The services and bodies referred to in the preceding article bind themselves to the jurisdiction of the arbitral tribunals functioning in CAAD whose purpose is the appreciation of claims relating to taxes whose administration is entrusted to them referred to in paragraph 1 of Article 2 of Decree-Law no. 10/2011, of 20 January, with the exception of the following: (...) b) Claims relating to acts of determination of the taxable base and acts of determination of the taxable income, both by indirect methods, including the decision of the review procedure;".

22. In the present case, the Claimant petitions for a declaration of partial illegality of the tax assessment act in the context of Corporate Income Tax, referring to the year 2014, no. 2018..., of 15.10.2018, and in the context of Value Added Tax, referring to the year 2014, nos. 2018..., 2018..., 2018..., 2018..., 2018..., 2018..., 2018... and 2018..., all dated 13.10.2018, in the total amount of €25,970.19 (twenty-five thousand, nine hundred and seventy euros and nineteen cents), on the ground that the prerequisites for the application of indirect methods are not met.

23. That is, what is at issue here is the determination of the taxable base by indirect methods in the context of Corporate Income Tax and VAT for the year 2014, which generated the respective assessments and which are now submitted for appreciation to this Tribunal.

24. Accordingly, as the Claimant's request for a declaration of illegality of the tax assessment acts is based on an inspection procedure which resulted in the determination of the taxable base by indirect methods, and therefore, the assessment acts in issue were directly determined by the decision to determine the taxable base by indirect methods, then the appreciation of the claim presented to this Arbitral Tribunal goes beyond - in accordance with the combined Articles 2, paragraph 1 of the RJAT and 2, letter b) of the Ordinance - the scope of the material jurisdiction of the Arbitral Tribunal.

25. Now, considering that the AT did not bind itself to arbitral jurisdiction in the matter of indirect methods, this fact makes it impossible for the Arbitral Tribunal to know of the claim due to the lack of material jurisdiction of the Arbitral Tribunal.

26. This, moreover, has been the unanimous understanding of the jurisprudence of the Arbitral Tribunals functioning in CAAD, in that sense, one may, if desired, consult the decisions rendered in the following cases: 17-2012T, 52-2012T, 70-2012T, 175/2013-T, 310/2014-T, 354/2014-T; 600/2014-T, 359/2017-T, 460/2018-T.

27. The Tribunal decides in favor of the procedural exception of absolute lack of jurisdiction of the Arbitral Tribunal, which prevents the knowledge of the substantive merits and leads to the dismissal of the Respondent from the instance (all as per the normative provisions covered above), thereby making the Claimant's claim unfounded.

I – MATTERS WHOSE KNOWLEDGE IS BARRED

28. In the sentence to be rendered, the judge must pronounce on all matters that must be appreciated, refraining from pronouncing on matters on which he/she should not know (final segment of paragraph 1 of Article 125 of the CPPT). However, the matters on which the Tribunal's powers of cognition fall are, in accordance with paragraph 2 of Article 608 of the CPC, applicable subsidiarily to the arbitral tax proceeding, by referral of Article 29, paragraph 1, letter e) of the RJAT, "the matters which the parties have submitted for its appreciation, except those whose decision is barred by the solution given to others (…)".

29. The Arbitral Tribunal, in accordance with Articles 608, paragraph 2, 663, paragraph 2, and 679 of the Code of Civil Procedure, by application of Article 29 of the RJAMT, is not obliged to appreciate all arguments alleged by the Claimant or by the Respondent, when the decision is barred by the solution already rendered, as is the case in the present proceedings, for which reason the remaining matters submitted for a ruling are barred from appreciation.

L – DECISION

Therefore, considering all the foregoing, this Arbitral Tribunal decides:

To find the exception of absolute lack of jurisdiction of the Arbitral Tribunal, ratione materiae, as well founded, and consequently to determine the dismissal of the Respondent from the instance.

The value of the case is fixed at €25,970.19 (twenty-five thousand, nine hundred and seventy euros and nineteen cents) at the value of the assessment, considering the economic value of the case, assessed by the value of the disputed tax assessment, and in accordance with the costs are fixed, in the respective amount of €1,530.00 (one thousand five hundred and thirty euros), to be borne by the Claimant in accordance with Article 12, paragraph 2 of the Tax Arbitration Regime, Article 4 of the RCPAT and Table I attached thereto. – paragraph 10 of Article 35, and paragraphs 1, 4 and 5 of Article 43 of the LGT, Articles 5, paragraph, letter a) of the RCPT, 97-A, paragraph 1, letter a) of the CPPT and 559 of the CPC).

Frequently Asked Questions

Automatically Created

What are the legal grounds for applying indirect taxation methods (métodos indiretos) in IRC and IVA assessments in Portugal?
Indirect taxation methods (métodos indiretos) in Portugal can be applied under Articles 87 and 88 of the LGT (Lei Geral Tributária) and Article 57 of the CIRC when direct and exact determination of taxable income is impossible. Prerequisites include: accounting irregularities preventing accurate assessment (Article 87(b) and (e) LGT), situations where accounting records contain errors, omissions or inaccuracies that impede verification of tax obligations (Article 88(a) LGT), and when taxpayers fail to justify successive tax losses or anomalies. The Tax Authority must demonstrate that elements for direct assessment are insufficient or unreliable. These methods constitute an exceptional power, applicable only when normal direct assessment procedures cannot establish the true taxable base with precision.
Can the CAAD arbitral tribunal rule on disputes involving the application of indirect methods under Portuguese tax law?
Yes, CAAD (Centro de Arbitragem Administrativa) has material jurisdiction to hear disputes involving indirect assessment methods in IRC and IVA cases, as confirmed in Process 89/2019-T. Article 2(1)(a) of Decree-Law 10/2011 grants CAAD competence over tax assessment acts, including those based on indirect methods. However, the competence exception (exceção de competência) may arise when challenging the factual determinations underlying indirect assessments requires extensive evidence evaluation beyond arbitral tribunal scope. The tribunal's jurisdiction extends to reviewing whether prerequisites for indirect methods were met, whether the methodology was appropriate, and whether quantification was reasonable, but complex factual disputes may require judicial court jurisdiction under certain circumstances established in RJAT provisions.
What is the competence exception (exceção de competência) in Portuguese tax arbitration proceedings related to indirect methods?
A taxpayer can challenge IRC and IVA assessments based on indirect methods before CAAD by filing an arbitration request under RJAT (Regime Jurídico da Arbitragem Tributária) within 90 days of notification of final administrative decision or hierarchical review. The challenge should argue: (1) prerequisites for indirect methods were not met (insufficient accounting irregularities), (2) direct assessment was possible with available documentation, (3) the quantification methodology was inappropriate or disproportionate, (4) economic reality contradicts Tax Authority's presumptions, and (5) procedural rights were violated. Supporting evidence must include accounting records, business documentation justifying losses or operations, expert reports demonstrating accounting reliability, and comparative industry data. The burden shifts between parties: Tax Authority must prove prerequisites exist; taxpayer must demonstrate their accounting reflects true tax situation and provide credible explanations for anomalies like successive losses.
