Process: 253/2013-T

Tax Type: IRS

Source: Original CAAD Decision

Summary

This arbitral decision (Process 253/2013-T) addresses whether the Portuguese Tax Authority (AT) can unilaterally reclassify a taxpayer from the organized accounting regime to the simplified IRS taxation regime mid-cycle. The case involved a female taxpayer whom the AT reclassified to the simplified regime for 2012-2014 after her annual income fell below €150,000, resulting in an IRS assessment of €10,815.49. The taxpayers challenged this assessment before CAAD, arguing the reclassification violated Article 28 of the IRS Code (CIRS), which establishes rules for taxation regime selection and permanence. The AT raised a preliminary objection claiming the Arbitral Tribunal lacked material competence because the dispute concerned cadastral classification (an upstream act) rather than the assessment itself. The Tribunal rejected this objection, applying the principle of unitary impugnation under Article 54 of CPPT, which requires that any illegality in prior interlocutory acts must be challenged through impugnation of the final lesive act—in this case, the tax assessment. The Tribunal held it had jurisdiction under Article 2(1)(a) of Decree-Law 10/2011. On the merits, the core issue was whether Article 28 CIRS permits the AT to unilaterally terminate a taxpayer's organized accounting regime before the minimum permanence period expires solely because turnover dropped below the €150,000 threshold. The AT argued that since the law provides for automatic application of the simplified regime below this threshold, the organized accounting regime ceases automatically when conditions for its maintenance are not met. This decision has significant implications for taxpayer rights regarding regime stability and the administrative authority's power to override taxpayer elections during mandatory permanence periods.

ARBITRAL DECISION

The Arbitrator Dr. André Festas da Silva, designated by the Ethics Board of the Administrative Arbitration Center (CAAD) to form the Arbitral Tribunal, constituted on 15 January 2014, decides as follows

I - REPORT

  1. On 8 November 2013, Mr. A and Mrs. B requested, under the terms and for the purposes provided in subparagraph a) of article 2, section 1, and article 10, both of Decree-Law No. 10/2011, of 20 January, the constitution of an Arbitral Tribunal with the designation of a sole arbitrator by the Ethics Board of the Administrative Arbitration Center, in accordance with the provisions of article 6, section 1, of said decree.

  2. The request for constitution of the Arbitral Tribunal was accepted by His Excellency the President of the CAAD and was notified to the Tax and Customs Authority (hereinafter referred to as AT or "Respondent") on 30 December 2013.

  3. The Claimants did not proceed with the appointment of an arbitrator, wherefore, under the provisions of article 5, section 2, subparagraph b), and article 6, section 1, of the RJAT, the undersigned was designated by the President of the Ethics Board of the CAAD to be part of this sole Arbitral Tribunal, having accepted in accordance with legally foreseen terms.

  4. The AT submitted its response on 13 February 2014.

  5. On 24 February 2014, the Claimants responded to the objection raised by the AT.

  6. On 20 March 2014, the first meeting of the Tribunal took place, under the terms and for the purposes of article 18 of the RJAT, with minutes being drawn up, which are also attached to the file.

  7. At that meeting, and as recorded in the respective minutes, the floor was given to the Illustrious Counsel for the Claimants, having requested the inclusion of a document authored by the Director of Services of the AT.

  8. The Respondent did not object to the inclusion of the document, having requested a period of ten days to make representations.

  9. The Tribunal decided to admit the inclusion of the document and granted a period of ten days for the AT to make representations.

  10. Subsequently, the Claimants requested that the legal arguments be presented in writing, to which the AT did not object.

  11. The Tribunal granted the request and notified the parties to submit legal arguments in writing.

  12. On 9 April 2014, the Claimants submitted their legal arguments.

  13. The Claimants request that the Arbitral Tribunal declare the illegality of the IRS assessment No. 2013 ..., dated 29/6/2013, relating to the 2012 tax year, in the total amount due of € 10,815.49.

I.A. The Claimant sustains its request, in summary, in the following terms:

  1. The AT classified the female Claimant under IRS for the three-year period 2012 to 2014 in the simplified taxation regime.

  2. This official classification violates the provisions of article 28, sections 1, 2, 3, 4, subparagraph a), section 5, and section 10, of the IRS Code.

  3. The female Claimant should have been classified under the organized accounting regime.

I.B In its Response, the AT invoked the following:

By exception, the AT alleged that the claimants did not invoke any defect attributable to the assessment.

The defect invoked by the Claimants is upstream of the assessment act – cadastral classification.

Consequently, this matter cannot be resolved before the Arbitral Tribunal, as the latter is materially incompetent.

The AT continues by alleging that it follows, from the outset, from the regime established in article 28 of the IRS Code that the legislator only expressly provided for the cessation of the simplified regime, saying nothing about the regime of cessation of the organized accounting regime.

However, noting that the simplified regime automatically covers taxpayers whose turnover is less than € 150,000.00, the AT concludes that the organized accounting regime also ceases when this limit is not reached.

As the law says nothing about the cessation of the organized accounting regime, the AT concludes that this occurs whenever the conditions for its maintenance are not met, and this happens when the taxpayer has not reached the minimum limit of turnover established in section 2 of article 28 of the IRS Code, regardless of whether or not a three-year period is in progress.

Finally, it is alleged by the AT that the request should not be granted in full since the Claimants only allege defects attributable to part of the assessment (income of category B of the female Claimant).

II. PRELIMINARY EXAMINATION

An exception of material incompetence of the Arbitral Tribunal is raised, which must be examined first.

The Respondent alleges that the Claimants did not invoke any defect from which the assessment may suffer. In the view of the AT, article 28 of the IRS Code does not deal with the rules of assessment. What is at issue is a defect – cadastral classification – upstream of the assessment. Thus, the Arbitral Tribunal is not materially competent to examine the defect upstream of the assessment.

Quid Juris?

The Claimants expressly impugned the IRS assessment. This is the act under review. The material competence of the Tribunal to examine the legality of this act results expressly from article 2, section 1, subparagraph a) of Decree-Law No. 10/2011 of 20 January.

As for the interlocutory act (cadastral classification) that occurred on a date prior to the assessment, the principle of unitary impugnation (article 54 of the CPPT) requires that, should it suffer from any defect, it must be invoked when impugning the final decision, that is, when impugning the assessment. Any illegality previously committed may be invoked when impugning the final decision. The interlocutory act is not susceptible to autonomous impugnation because it, in itself, is not lesive, that is, it is not susceptible to causing immediate negative legal effects in the taxpayer's legal sphere.

As Jorge Lopes de Sousa asserts: "In tax procedures that lead to an act of assessment of a tax, the legal sphere of the interested parties is only affected by that act and, therefore, as a rule, it will be it and only it the lesive and contentiously impugnable act." In CPPT Annotated, Áreas Editora, Vol. I, 6th Edition, 2011, p. 468

In compliance with the provisions of article 54 of the CPPT, the illegality of the cadastral classification can only be examined judicially by way of impugnation of the assessment, just as the Claimants did.

Based on the foregoing, under the terms of article 2, section 1, subparagraph a) of Decree-Law No. 10/2011 of 20 January, the Tribunal concludes that it is materially competent, and therefore the raised exception is unfounded[1].

The Tribunal is competent and is regularly constituted, under the terms of articles 2, section 1, subparagraph a), 5, and 6, all of the RJAT.

The proceedings are proper.

The parties have standing and legal capacity.

The parties are legitimate and are legally represented, under the terms of articles 4 and 10 of the RJAT and article 1 of Ordinance No. 112-A/2011, of 22 March.

There are no other preliminary matters to examine nor defects that invalidate the proceedings.

It is now necessary to examine the merits of the request.

III. THEMA DECIDENDUM

The substantive issue in the present proceedings is whether the AT can unilaterally alter the taxpayer's taxation regime, where said taxpayer had opted for the organized accounting regime before the minimum period of permanence had elapsed, by virtue of having presented an annual net income less than € 150,000.00 in the previous tax year.

IV. FACTUAL MATTERS

IV.1. Proven Facts

Before proceeding to examine the issues, it is necessary to present the factual matters relevant to their understanding and decision, which, having examined the documentary evidence, the attached tax administrative proceedings, and taking into account the alleged facts, are established as follows:

  1. The female Claimant was classified, in category B of IRS, under the general taxation regime – organized accounting – for the three-year period 2008-2010, commencing on 1/1/2008.

  2. In 2010, the female Claimant obtained income from category B, in the amount of € 190,209.89.

  3. In 2011, the female Claimant obtained income from category B, in the amount of € 127,498.15.

  4. On 12/3/2012, the female Claimant was classified by the AT, under IRS, in the organized accounting regime, since 1/1/2011.

  5. Subsequently, the AT classified the female Claimant under IRS for the three-year period 2012-2014 in the simplified taxation regime.

  6. This change was never communicated to the Claimant.

  7. The Claimants managed to submit their respective IRS model 3 declaration for 2012, with the declaration of income from category B of the Claimant calculated on the basis of accounting, but the AT's computer system did not allow it.

  8. Therefore, the Claimants submitted the IRS declaration for 2012, with the declaration of income from category B of the Claimant calculated on the basis of the simplified taxation regime.

  9. The assessment sub judice was determined by calculating the taxable income of category B of the Claimant, in accordance with the rules of the simplified taxation regime.

  10. The Claimants proceeded with the respective payment.

IV.2. Facts Deemed Not Proven

There are no facts deemed not proven, since all facts relevant to the examination of the request were deemed proven.

IV.3. Reasoning of the Factual Matters

The proven facts constitute uncontested matter and are documented in the proceedings.

The facts set out in numbers 1 to 10 are taken as established by agreement of the parties, by examination of the administrative proceedings, and by documents submitted by the Claimants (documents 1 to 2 of the request for constitution of the Arbitral Tribunal and document submitted on 20.03.2014).

V. APPLICATION OF LAW TO THE FACTS

The question to be decided is related to the interpretation of article 28 of the IRS Code, namely the minimum period of permanence in the organized accounting regime and the conditions for cessation of this regime.

At the time of the facts under examination, 2012, article 28 of the IRS Code had the following wording:

Article 28
Methods of determination of business and professional income

1 - The determination of business and professional income, except in the case of allocation provided for in article 20, is made:

a) On the basis of the application of the rules arising from the simplified regime;

b) On the basis of accounting.

2 - Taxpayers who, in the course of their activity, have not exceeded in the immediately preceding tax period an annual net amount of income of this category of (euro) 150,000 are covered by the simplified regime.

3 - Taxpayers covered by the simplified regime may opt for the determination of income on the basis of accounting.

4 - The option referred to in the previous number must be formulated by the taxpayers:

a) In the statement of commencement of activity;

b) By the end of March of the year in which they intend to alter the method of determination of income, by means of the presentation of a statement of alterations.

5 - The minimum period of permanence in either of the regimes referred to in section 1 is three years, renewable for equal periods, except if the taxpayer communicates, in accordance with subparagraph b) of the previous number, the alteration of the regime under which it is covered.

6 - The application of the simplified regime ceases only when the amount referred to in section 2 is exceeded in two consecutive tax periods or, when exceeded in a single tax year, in an amount exceeding 25%, in which case taxation by the organized accounting regime takes place from the tax period following the occurrence of any of these facts.

7 - The base values necessary for the determination of taxable income are subject to correction by the General Directorate of Taxes in accordance with article 39, with the provisions of the previous number applying when the assumptions referred to therein are met.

8 - If income received results from services rendered to a single entity, except in the case of service provision by a partner to a company covered by the fiscal transparency regime, in accordance with subparagraph b) of section 1 of article 6 of the Corporate Income Tax Code, the taxpayer may opt for taxation in accordance with the rules established for category A, with that option being maintained for a period of three years.

9 - Whenever application of the technical and scientific base indicators referred to in section 1 of article 31 determines a taxable income greater than that resulting from the coefficients established in section 2 of the same article, the taxpayer may, in the tax year of entry into force of those indicators, opt, within the period and in the manner provided for in subparagraph b) of section 4, for the organized accounting regime, even if the minimum period of permanence in the simplified regime has not elapsed.

10 - In the tax year of commencement of activity, classification in the simplified regime is made, provided that other requirements are met, in accordance with the annual estimated income value, contained in the statement of commencement of activity, if the option referred to in section 3 is not exercised.

11 - If, following cessation of activity, it is resumed before 1 January of the year following that in which 12 months have been completed, counted from the date of cessation, the regime for determination of business and professional income to be applied is the one that was in force on the date of cessation.

12 - The provision in the previous number does not prejudice the possibility of the DGCI authorizing the alteration of regime, upon request of the taxpayers, when it is verified that there has been a substantial modification of the conditions for the exercise of the activity.

13 - The provisions of section 11 are excepted in situations in which the resumption of activity occurs after the minimum period of permanence has ended.

The Claimants impugned the assessment for the 2012 tax year on the basis of incorrect classification of the female taxpayer in the simplified taxation regime.

The taxpayer in 2008 opted for the organized accounting regime. In the tax years 2008, 2009, 2010, and 2011, she was taxed under IRS according to the organized accounting regime.

In 2011, the taxpayer declared income from category B in the amount of € 127,498.15.

The AT alleges that, as the taxpayer declared income less than € 150,000.00 in 2011, and did not make the option for the organized accounting regime by March 2012, she should be classified in the simplified regime.

Based on the foregoing, what would be the taxation regime in force for 2012? Taking into account the value of the taxpayer's income in 2011, should she, in March 2012, have formally opted for the organized accounting regime?

Under the terms of article 28, section 5 of the IRS Code, the minimum period of permanence in either regime (simplified or based on accounting) is three years, renewable for equal periods.

In 2008, the taxpayer opted for the organized accounting regime, remaining in that regime in 2009 and 2010.

In 2011, a new cycle began. In the tax year 2011, the taxpayer was taxed in accordance with the rules of organized accounting.

However, in the tax year 2012, the AT classified the taxpayer in the simplified regime, alleging that the taxpayer had income less than € 150,000.00 in the tax year 2011 and did not opt for the organized accounting regime by March 2012.

It should be borne in mind that the simplified regime is a subsidiary regime, that is, taxpayers covered by it may opt for the organized accounting regime (article 28, section 3 of the IRS Code).[2]

In the case at hand, the taxpayer made the choice for organized accounting in 2008.

Law No. 53-A/2006 of 29/12 altered the wording of section 5 of article 28 and imposed the obligation of permanence for a minimum period of three years in either regime. This alteration applies to the case being adjudicated.

Thus, the first cycle of permanence in organized accounting occurred over the tax years 2008, 2009, and 2010. The taxpayer not having opted for that alteration, in accordance with the latter part of article 28, section 5 of the IRS Code, it is clear that automatically the period of permanence in the organized accounting regime under which she was covered in the previous three-year period was extended for an equal period. In 2011, a new three-year cycle began in the organized accounting regime, which extends through 2012 and 2013.

Following the teachings of Prof. José Xavier de Bastos: "With the new wording of section 5 of article 28 and the consequent fixing of the period of permanence in either regime at three years, a source of difficulties was thus closed for taxpayers who decide to opt for the organized accounting regime. They now know that the option is valid for three years, renewable for equal periods, and that only if they wish to alter their regime (in this case, obviously if they meet the conditions for doing so) are they obliged to communicate it through a statement of alterations." In IRS Real Incidence and Determination of Net Income, Coimbra Editora, 2007, p. 181

Having the taxpayer earned income less than € 150,000.00 in 2011, was she required to communicate, by March 2012, the option for the organized accounting regime?

The exceptions that cause the three-year minimum period to cease are provided for in article 28, section 6 of the IRS Code:

"The application of the simplified regime ceases only when the amount referred to in section 2 is exceeded in two consecutive tax periods or, when exceeded in a single tax year, in an amount exceeding 25%, in which case taxation by the organized accounting regime takes place from the tax period following the occurrence of any of these facts."

In the case of the cited provision, the simplified regime ceases and the taxpayer is transferred, in the following tax year, compulsorily, independently of whether or not the mandatory three-year cycle has elapsed, to the organized accounting regime.

It happens that the legislator did not provide for any situation that would cause the organized accounting regime to cease during the three-year cycle. Not having the legislator provided for that situation, the interpreter cannot understand that the regime ceases when the taxpayer does not have income exceeding € 150,000.00 and has not opted for the organized accounting regime.

The AT's interpretation has no correspondence with the letter of the law and is therefore contrary to the provisions of article 9, section 2 of the Civil Code, applicable by reference from article 2, subparagraph d) of the General Tax Law.

Furthermore, in ascertaining the meaning and scope of the law, the interpreter shall presume that the legislator adopted the most correct solutions (article 9, section 3 of the Civil Code). Not having the legislator provided for any situation that would cause the organized accounting regime to cease during the three-year cycle, the interpreter must conclude that its absence is the most correct solution.

Even if it were understood that there is a gap, which in this Tribunal's view does not exist, it would not be susceptible to analogical integration because such is expressly forbidden by article 11, section 4 of the General Tax Law.

Furthermore, at the time of the first meeting of the Arbitral Tribunal held on 20/03/2014, the Claimants attached an email from 14.03.2014 from the Director of Services of IRS, sent to the services, with the following content: "Given that doubts have been raised in the interpretation of article 28 of the IRS Code regarding taxpayers who, having exercised the option for the organized accounting regime, were reclassified by the services in a different regime, it was, by order of the legal substitute of the General Director, dated 2014.01.31, sanctioned the understanding, in summary, that once the option for the organized accounting regime is exercised, that option is valid and is maintained during the three-year period, this being renewable for equal periods, whereby the taxpayer will only need to return to the simplified regime at their own initiative, in accordance with the provisions of section 5 of article 28 of the IRS Code, thus not being relevant, for purposes of classification, the variations in the net amount of income of category B that occurred."

Having attached this document, the respondent chose to say nothing. Now, the orientation of the Director of Services is in line with the interpretation adopted by this Tribunal.

Therefore, the classification of female taxpayer B in the simplified regime in the tax year 2012 carried out by the AT, on the ground that her income in 2011 was less than € 150,000.00 and that she did not make the option for the organized accounting regime by March 2012, lacks legal foundation[3]. The taxpayer is compulsorily in the organized accounting regime for the three-year period of 2011, 2012, and 2013.

The impugned assessment violates the provisions of article 28, section 5 of the IRS Code, and should therefore be annulled.

The AT, in articles 35 to 37 of its response, without conceding, alleges that the request should not be granted in full since the Claimants only allege defects attributable to part of the assessment (income of category B of the female Claimant).

It is true that a tax assessment act is by nature a divisible act and is consequently susceptible to partial annulment in the respective impugnation proceeding.[4] Partial annulment is admitted in article 100 of the General Tax Law.

It happens that there are cases in which partial annulment is not possible. In the case at hand, the alteration of the determination of taxable income and the possible alteration of the applicable rates as a result of the alteration of tax brackets necessarily implies a new assessment.

Based on the foregoing, partial annulment is not possible.[5] Accordingly, it is decided to annul the assessment in its entirety.

VI. ON THE REQUEST FOR COMPENSATORY INTEREST

Pursuant to article 43, section 1, of the General Tax Law, "compensatory interest is due when it is determined, in a gracious complaint or judicial impugnation, that there was an error attributable to the services resulting in payment of a tax debt in an amount greater than legally due."

The requirements for the right to compensatory interest provided for in article 43, section 1, of the General Tax Law are as follows:

1 - That there is an error in an act of assessment of a tax;

2 - That the error is attributable to the services;

3 - That the existence of that error is determined in a process of gracious complaint or judicial impugnation;

4 - That as a result of that error, payment has been made of a tax debt in an amount greater than legally due.

(See Jorge Lopes de Sousa, CPPT Annotated and Commented, Volume I, Áreas Editora, 6th Edition, 2011, p. 530).

The annulment of the IRS assessment object of the attached impugnation proceedings was due to an incorrect interpretation and application of the Law. Incorrect interpretation of the Law leads to the consequent annulment of the consequent tax act that is based on it.

Incorrect interpretation and application of the Law falls within the error regarding the premises of law, which functions as a requirement for the right to compensatory interest provided for in the examined article 43, section 1, of the General Tax Law. The error is attributable to the services of the AT, having resulted in a payment greater than due.

In these terms, it must be considered that the requirements for condemning the Public Treasury to pay compensatory interest to the Claimants are met, by virtue of the annulment of the assessment, given that all requirements provided for in article 43, section 1, of the General Tax Law are met.

The request for compensatory interest therefore succeeds, which should be calculated, at the rate determined, in accordance with the provisions of article 43, section 4, of the General Tax Law, between the days on which the improper payment was made until the date of issuance of the corresponding credit note.

VII. DECISION

Based on all the foregoing, it is decided:

a) To find the raised exception of material incompetence of the Arbitral Tribunal unfounded;

b) To find the present impugnation meritorious, by violation of law, annulling the impugned assessment;

c) To find the request for payment of compensatory interest meritorious, at the legal rate, counted from the date of payment of the assessment until the moment of restitution of the amount improperly assessed and paid.

The value of the case is fixed at € 10,815.49 in accordance with article 97-A, section 1, a), of the CPPT, applicable by virtue of subparagraphs a) and b) of section 1 of article 29 of the RJAT and section 2 of article 3 of the Regulation of Costs in Tax Arbitration Proceedings.

The value of the arbitration fee is fixed at € 918.00, in accordance with Table I of the Regulation of Costs in Tax Arbitration Proceedings, to be paid in full by the Respondent, since the request was granted in full, in accordance with articles 12, section 2, and 22, section 4, both of the RJAT, and article 4, section 4, of the cited Regulation.

Let it be notified.

Frequently Asked Questions

Automatically Created

Can the Portuguese Tax Authority unilaterally assign a taxpayer to the simplified IRS taxation regime?
Under Portuguese tax law, the Tax Authority's power to unilaterally assign taxpayers to the simplified IRS regime is subject to specific legal constraints. According to Article 28 of the IRS Code, the simplified regime applies automatically to taxpayers with annual gross income below €150,000. However, when a taxpayer has actively opted for the organized accounting regime, the AT's ability to unilaterally reverse this election—particularly during the mandatory three-year permanence period—is legally contested. This arbitral decision examined whether the AT exceeded its authority by reclassifying a taxpayer mid-cycle solely because income fell below the threshold. The principle established is that taxpayers who validly elect organized accounting are entitled to regime stability for the minimum permanence period, and unilateral administrative reclassification may constitute an illegal act challengeable through arbitration under the principle of unitary impugnation.
What are the legal requirements for changing from simplified regime to organized accounting under Article 28 of the CIRS?
Article 28 of the IRS Code establishes that taxpayers in Category B income with annual gross receipts below €150,000 are automatically placed in the simplified taxation regime unless they opt for organized accounting. To change from the simplified regime to organized accounting, taxpayers must submit a declaration during the month of January or within the first 15 days of beginning activity (Article 28(4)(a) CIRS). Once the option is exercised, the taxpayer must remain in the organized accounting regime for a minimum period of three years (Article 28(5) CIRS). The regime only ceases after this three-year period if the taxpayer submits a declaration of cessation or if specific conditions under Article 28(10) are met. Key requirements include: maintaining proper accounting books, issuing compliant invoices, and meeting the turnover threshold. The legal question in this case centered on whether falling below the €150,000 threshold during the permanence period triggers automatic reversion to the simplified regime or whether the three-year commitment protects the taxpayer's election.
How can taxpayers challenge an incorrect IRS tax regime classification through CAAD arbitration?
Taxpayers can challenge incorrect IRS tax regime classifications through CAAD (Centro de Arbitragem Administrativa) by following these procedures: First, file a formal request for constitution of an arbitral tribunal under Article 2(1)(a) and Article 10 of Decree-Law 10/2011 within the statutory deadline. The challenge must target the final lesive act—typically the tax assessment notice—rather than the preliminary cadastral classification itself. Under Article 54 of the Tax Procedure Code (CPPT), the principle of unitary impugnation requires that any illegality in upstream administrative acts (such as regime classification) be invoked when challenging the final tax assessment. The tribunal has material competence to examine all defects affecting the assessment, including prior classification errors. Taxpayers must clearly identify the contested assessment, specify the legal grounds (such as violation of Article 28 CIRS provisions), and request annulment of the illegal act. The CAAD process offers a faster, specialized alternative to judicial tax courts, with arbitrators designated by the CAAD Ethics Board and decisions typically rendered within months.
What is the difference between the simplified taxation regime and the organized accounting regime for IRS purposes in Portugal?
The simplified taxation regime and organized accounting regime represent two distinct methods of determining taxable income for Category B (self-employment and business) income under Portuguese IRS law. The simplified regime applies a statutory coefficient to gross receipts to determine taxable income, without requiring detailed accounting records—taxpayers need only maintain basic documentation of income and certain expenses. This regime automatically applies to taxpayers with annual gross income below €150,000. In contrast, the organized accounting regime requires maintaining complete double-entry bookkeeping, detailed financial records, and compliance with accounting standards (SNC or SNC-ME). Taxable income is calculated based on actual profit (receipts minus deductible expenses) rather than coefficients. The organized accounting regime is mandatory for taxpayers exceeding the €150,000 threshold and optional for those below it. Key differences include: greater administrative burden but potentially more accurate tax liability under organized accounting; simplified compliance but less flexibility to deduct actual expenses under the simplified regime; and different obligations regarding invoicing, record retention, and reporting to the Tax Authority.
What are the deadlines and procedures for opting out of the simplified IRS regime under Portuguese tax law?
The deadlines and procedures for opting out of the simplified IRS regime are governed by Article 28 of the IRS Code. To opt for organized accounting from the simplified regime, taxpayers must submit a formal declaration (declaração) to the Tax Authority during the month of January preceding the tax year for which the option will take effect, or within 15 days of commencing business activity for new taxpayers. Once the option is exercised, it becomes binding for a minimum period of three consecutive years (Article 28(5) CIRS). To revert from organized accounting back to the simplified regime after the mandatory period, taxpayers must submit a cessation declaration during January of the year following completion of the three-year period. The option takes effect for the entire tax year—mid-year changes are not permitted except in specific circumstances such as commencement or cessation of activity. Importantly, this case questions whether the Tax Authority can override a taxpayer's valid election before the three-year period expires based solely on the taxpayer's income falling below the €150,000 threshold, or whether the taxpayer's election must be respected for the full mandatory permanence period regardless of income fluctuations.
