Summary

This CAAD arbitral decision (Process 178/2018-T) addresses the IRS taxation of a French national who established fiscal residency in Portugal in 2013 and obtained non-habitual resident (RNH) status. The claimant challenged an IRS assessment of €57,389.01 for 2013, arguing that income earned in France should not be taxed in Portugal under the RNH regime and double taxation conventions. The taxpayer contended he moved to Portugal at the end of 2013, registered as a tax resident, acquired property, and obtained RNH status retroactively for 2013. He declared French-source income (from employment and life insurance) in his Portuguese tax return but believed no Portuguese tax was due because he had already paid tax in France. The case involved procedural complexities: an initial assessment of €17,697.74, an administrative complaint, and subsequently a second, larger assessment without proper notification of the right to be heard. The claimant initially sought to expand the arbitral claim to include both assessments but later withdrew this request due to jurisdictional value limits for single-arbitrator tribunals under Article 5 of RJAT. Key legal issues include: determination of fiscal residency timing, application of the RNH regime to French-source income, compliance with double taxation treaty provisions, procedural defects (lack of hearing notification and insufficient statement of reasons), and whether income was correctly characterized and valued. The decision illustrates the interaction between Portuguese domestic tax law (IRS Code Article 81 on RNH), international tax treaties, and taxpayer procedural rights in CAAD arbitration.

ARBITRAL DECISION

I. REPORT

On 9 April 2018, A..., of French nationality, with the NIF..., resident in..., ..., ...-... ..., ..., requested, under the terms set forth in paragraph a), of section 1, of article 2 of Decree-Law No. 10/2011, of 20 January, which approved the Legal Regime for Arbitration in Tax Matters (hereinafter "LRATM"), and of Ordinance 112-A, of 22 March, the constitution of an Arbitral Tribunal, in which the Tax and Customs Authority is the Respondent (hereinafter simply "Respondent" or "TA"), with a view to declaring illegal and consequently annulling the act of assessment of Personal Income Tax and compensatory interest with the number 2017..., in the total amount of € 57.389,01, relating to the year 2013.

The request for constitution of the Arbitral Tribunal was accepted by the Honorable President of CAAD and notified to the Respondent on 16 April 2018.

The Deontological Council designated the undersigned as arbitrator, who communicated acceptance of the appointment within the applicable time limit.

On 1 June 2018, the Parties were duly notified of this designation, and did not manifest the intention to refuse the arbitrator's designation, in accordance with the combined terms of article 11, section 1, paragraphs a) and b) of the LRATM and articles 6 and 7 of the Deontological Code.

In conformity with what is provided in paragraph c), of section 1, of article 11 of the LRATM, the single arbitral tribunal was constituted on 21 June 2018, and on the same date, the TA was notified to respond.

Before presentation of the response by the TA, the Claimant, having been notified of the dismissal of the administrative complaint filed in relation to an assessment act related to that covered by the request for arbitral decision, in the amount of € 17.697,74, came, on 3 September 2018, to petition for an extension of the scope of the request, which then came to concern the annulment of two acts – the initially identified assessment act and the dismissal of the administrative complaint.

After the foregoing, on 10 September 2018, the Respondent submitted a response in which it petitioned that the request for arbitral decision be judged unfounded due to lack of legal basis, maintaining the disputed tax acts in the legal order and accordingly absolving the Respondent of the claim.

Having been notified of the Respondent's response, the Claimant stated its position, in "response to the response," confirming what had already been alleged in the request for arbitral decision. Having been notified of the Claimant's petition, the Respondent petitioned the removal of the same for inadmissibility of the "reply" presented by the Claimant.

On 10 October 2018, pronouncing itself on the request for extension of scope presented by the Claimant, this tribunal requested the Claimant to indicate the intention to maintain the same, given its impact on the value of the case and which, in the tribunal's view, would result in its lack of competence as, with the extension, it would exceed the jurisdiction value of the single tribunal, in accordance with article 5 of the LRATM.

In the silence of the Claimant regarding the clarification requested by the Tribunal, and considering essential its pronouncement regarding the intention to maintain the request for extension of scope, within the scope of the established autonomy of the tribunal in conducting the proceedings, the tribunal decided to convene the meeting provided for in article 18 of the LRATM, having also scheduled, for the same date, the examination of the witnesses listed by the Claimant.

At the said meeting, which took place on 10 December 2018, the Claimant manifested the intention to withdraw from the request for extension of scope of the request for arbitral decision, and the witnesses listed by him were also examined, by Skype and with translation by means of a translator indicated by the Claimant.

Notified for simultaneous submissions within a period of 15 days, the Parties presented submissions (the Claimant on 4 January 2018 and the Respondent on 8 January 2018), maintaining, with adjustments, the arguments already put forth.

Summary of the Parties' Positions

a. Of the Claimant:

In accordance with the request for arbitral decision and submissions, the Claimant understands that:

- The Claimant resided in France until the end of 2013, where he performed functions as Administrator at B...;

- At the end of 2013, the Claimant and his wife decided to emigrate to Portugal, establishing their residence there;

- To this effect, the Claimant obtained, on 14 November 2013, a tax identification number as a non-resident, having later, but still in 2013, changed his status to fiscal resident in Portugal;

- In early 2014, the Claimant requested the attribution of the status of non-habitual resident, by reference to 2013, which was accepted by the TA;

- In parallel, the Claimant and his wife purchased a house in ..., which they declared as being their own permanent residence;

- As a fiscal resident in Portugal in 2013, and considering the rules in force at the time, the Claimant submitted an income tax return, for purposes of Personal Income Tax, including income earned in France, despite having earned no income or exercised any activity in Portugal;

- The first return was submitted on 30 May 2014, with a substitute return delivered on 30 June 2014;

- On 4 September 2014, the Claimant was notified of the Personal Income Tax assessment note with the total amount due of € 17.697,74;

- Notwithstanding the said assessment, the Claimant understood that no tax was due in Portugal by virtue of the non-habitual resident regime, since tax had been paid in France on those incomes;

- Moreover, he realized that the said assessment was based on the declared income of € 117.977,00 and that the income actually received would have been € 86.677,00 and, as well, that such income would have been incorrectly declared in the submitted return;

- Accordingly, the Claimant filed an administrative complaint against the said assessment, on 21 January 2015, requesting correction of material errors and defending the annulment of the Personal Income Tax assessment for non-compliance with article 81 of the Personal Income Tax Code regarding taxation in Portugal of income obtained by non-habitual residents;

- In particular, and as mentioned, the Claimant understands that, having effectively paid tax in France on the income earned – amount received under a life insurance contract –, no additional tax will be due in Portugal;

- Without having received a response to the complaint, the Claimant was notified of a new assessment, on 7 December 2017, now in the total amount of € 57.398,02, with the total amount to pay of € 39.491,27 (considering the settlement with the amount previously paid in relation to the initial assessment) without ever having been notified to exercise the right of hearing, which only occurred on 27 March 2018 and after having submitted a request for statement of reasons;

- The Claimant thus understood to challenge the new assessment, providing a bank guarantee for this purpose;

- After submission of the request for arbitral decision, the Claimant was notified of the express dismissal of the administrative complaint filed against the original assessment;

- In view of the foregoing, the Claimant understands, first of all, that the disputed assessment – the second assessment – suffers from the defect of omission of essential formality due to lack of notification to exercise the right of hearing;

- Additionally, the Claimant also understands that the disputed assessment suffers from the defect of lack of statement of reasons, since it does not result from the assessment that is the subject of the present request for arbitral decision the reason for this assessment, nor are the terms and decision-making process of the Respondent and its respective legal basis for the act performed discernible;

- Thus, the Claimant understands that the assessment is invalid due to omission of essential formality, also imputing to the disputed assessment the defect of violation of the statute of limitations deadline;

- As to the material aspects of the assessment, and as already mentioned, the Claimant understands that the assessment suffers from the defect of violation of law, in particular the provisions of article 81 of the Personal Income Tax Code regarding the elimination of international legal double taxation concerning income earned abroad by residents in Portugal covered by the non-habitual resident regime;

- Accordingly, the Claimant understands that, under the terms of paragraph a) of section 4 of article 81 of the Personal Income Tax Code, the income at issue here, obtained in France, should be exempt from tax in Portugal, taking into account that it was effectively taxed in France, thus fulfilling the legal requirement for application of the exemption method in Portugal;

- Nevertheless, the Claimant further argues that, in any case, he should be considered resident in France in the year 2013, insofar as he lived in France until the end of the year, as he understands proven by the testimony of the witnesses examined and other documentation attached to the proceedings, whereby Portugal should not have tax jurisdiction;

- In particular, and in this respect, the Claimant understands that, in 2013, the connection to Portuguese territory is merely residual and that, for that reason, fiscal residence in Portugal for taxation of the income at issue here cannot be established;

- The Claimant concludes to the effect that, even if fiscal residence in Portugal is established that year, under the terms of the domestic law, article 4 of the Convention for the Avoidance of Double Taxation ("DTC") celebrated between Portugal and France would always require consideration of fiscal residence in France for purposes of elimination of double taxation.

b. Of the Respondent:

In turn, in accordance with the response and submissions presented, the Respondent argues that:

- Regarding the purported defect of lack of statement of reasons, the Respondent understands that the assessments in question merely limit themselves to assessing the tax based on the Claimant's returns, whereby the assessment note is sufficient as statement of reasons;

- The Respondent further understands that, having responded to the request for certification made by the Claimant under article 37 of the Code of Tax Procedure and Process, any defect that, by mere theoretical exercise, could be imputed to the assessment acts, is cured;

- As to the omission of essential formality (prior hearing), the Respondent understands that, as to the first assessment, the assessment is carried out based on the elements declared by the Claimant, whereas, as to the second assessment, at issue here, only a calculation error in computer processing is corrected, and for these reasons, there is no need to exercise the right of prior hearing;

- Having regard to the foregoing, the Respondent understands that the right of hearing only exists in the case of a procedure which concerns matters of fact and not applicable legal norms;

- As to the legal justification of the assessments carried out, contested by the Claimant in the present request for arbitral decision, the Respondent understands there to be an error in understanding the applicable norms, as well as an irremediable contradiction in the line of argumentation on the part of the Claimant;

- Thus, regarding the reading of the provisions of article 81 of the Personal Income Tax Code, the Respondent emphasizes that the exemption from tax in Portugal depends on the income in question being able to be taxed, in this case, in France, under the terms of the DTC celebrated between Portugal and France;

- That is, it is not a question of whether the income was actually taxed in France or not, but of knowing whether the income could have been taxed in France under the applicable DTC;

- As such, by classifying this income under article 23 of the said DTC, the Respondent reaches the conclusion that it may only be taxed in the state of residence;

- And from this classification the Respondent draws the conclusion that the income should always be considered taxable in Portugal, either because the Claimant is, as he himself declares and by virtue of the applicable legislation, a fiscal resident in Portugal in the year 2013, or because the applicable DTC does not allow France to tax the income in question (even though it did occur);

- In particular regarding the condition of resident in Portugal, the Respondent emphasizes the contradiction in which the Claimant understands to incur by declaring himself, on the one hand, as a fiscal resident in Portugal in 2013 and covered by the non-habitual resident regime and, on the other hand, as a non-fiscal resident in Portugal...;

- In this regard, and finally, the Respondent understands that the statements of the witnesses listed by the Claimant were confused and do not confirm with certainty the moment when the Claimant moved to Portugal;

- In the Respondent's view, the Claimant is effectively a fiscal resident in Portugal in 2013 – because he declared himself as such in compliance with the tax rules applicable at the time –, being that, in that measure, and by effect of the provisions of article 81 of the Personal Income Tax Code, combined with the DTC celebrated between Portugal and France, the income earned will be effectively subject to tax in Portugal, without prejudice to the tax paid in France.

II. ADJUDICATION

1. The Arbitral Tribunal is competent and was regularly constituted, in accordance with articles 2, section 1, paragraph a), 5 and 6, all of the LRATM.

2. The parties have legal personality and capacity, are legitimately represented, in accordance with articles 4 and 10 of the LRATM, and article 1 of Ordinance No. 112-A/2011, of 22 March.

3. No exceptions were invoked that require examination.

4. The proceedings do not suffer from defects that would invalidate them.

5. With respect to the Claimant's request for "response to the response" from the Respondent, as this is not the procedural moment for doing so, it should be removed from the case file, taking into account the evidence produced with the request for arbitral decision, response, witness testimony and respective submissions.

III. REASONING

III.1. FACTUAL MATTER

The factual matter relevant to understanding and deciding the case, after critical examination of the documentary evidence attached to the initial petition, the administrative proceedings, the response and the submissions of the Claimant and the Respondent, is established as follows:

A – Established Facts

a. The Claimant resided in France until he came to reside in Portugal, having been a fiscal resident there until that date;

b. The Claimant requested a Portuguese tax identification number as a non-resident, on 14 November 2013;

c. Subsequently, at the end of 2013, the Claimant registered as a fiscal resident in Portugal;

d. Having requested registration as a non-habitual resident, with retroactive effect to the date of acquisition of residence, on 13 January 2014;

e. During the year 2013, while a fiscal resident in France, the Claimant earned income under a life insurance contract, paid by an entity resident in France;

f. The Claimant declared such income in the income tax return he filed in Portugal, for 2013, although he reported them as income exempt from tax under the non-habitual resident regime.

B – Unestablished Facts

No facts with relevance to the discussion of the case were deemed unestablished.

III.2. MOTIVATION

Regarding factual matter, the Tribunal does not have the duty to pronounce on all alleged matters, but rather has the duty to select what is relevant to the decision, taking into account the ground (or grounds) of claim that substantiates the request submitted by the Claimant.

With respect to assessment of the evidence, the Tribunal formulates its judgment, in attention to the principle of free assessment, based on the examination and evaluation it makes of the means of proof brought to the proceedings and in accordance with its experience.

Thus, the Tribunal's conviction was based on the documentary evidence attached to the case file as well as on the positions assumed by the Respondent and the Claimant.

III.3. OF THE LAW

1. THEMA DECIDENDUM:

Having regard to the foregoing, the present request for arbitral decision concerns, essentially, the legality of the (second) Personal Income Tax assessment carried out by the Respondent.

In these terms, and considering what is provided in article 124 of the Code of Tax Procedure and Process, applicable by virtue of what is provided in article 29, section 1, paragraph a) of the LRATM, the controversial questions in the present proceedings, and to which it is important to provide answers, are, simply put, the following:

1. Should the Claimant be considered a fiscal resident in Portugal, in 2013, for purposes of taxation of the income at issue here?

2. If the answer to the second question is positive, should the income earned by the Claimant be exempt from tax in Portugal under the terms of the norms for elimination of international legal double taxation applicable (article 81 of the Personal Income Tax Code and the DTC celebrated between Portugal and France)?

3. If the answers to the first two questions are in the direction of maintaining the disputed assessment, should it be considered that the said assessment suffers from some formal defect that invalidates it?

2. LEGAL REASONING:

Having reached this point, it will be important to recall, for good decision of the case, the positions of the Parties in this respect.

On one hand, the Claimant understands that, without prejudice to having declared himself as resident in the period in question, he should be considered non-resident in Portugal in that same period, with residence in French territory prevailing due to having a stronger connection with it.

The Respondent, on the other hand, understands that such argumentation presents itself as contradictory and irremediably irreconcilable.

It is important, in this respect, to recall that, at the time of the facts – 2013 –, article 13, section 7 of the Personal Income Tax Code provided that "The personal and family situation of taxpayers (...) is that which is verified on the last day of the year to which the tax refers."

Furthermore, contrary to what happens today under the terms of section 3 of article 16 of the Personal Income Tax Code, the tax in question did not provide for the concept of partial fiscal residence.

In that measure, a person who acquired fiscal residence in Portugal, as was the case of the Claimant in the year in question, in the course of the year, acquired that status with respect to the entire year.

As such, it should not raise doubts the conclusion that the Claimant should be considered a fiscal resident in Portugal for the year 2013, under the terms of the Personal Income Tax Code.

However, the question posed does not end there.

In fact, having the Claimant also been resident in France in that year – that is to say, for most of that year –, at a moment prior to acquisition of fiscal residence in Portugal, and having the income been earned during the pendency of that fiscal residence in France, there will be a need to observe the existence of a conflict of residences.

And while under the terms of the internal legislation of each country, each of them has the right to consider – and does consider – the Claimant as its resident for purposes of taxation of the income in question, one cannot, however, obscure the fact that the countries in question celebrated a DTC which regulates, among others, precisely situations of double residence, avoiding, as in the case at hand, the multiplication – more precisely, the superposition – of tax claims.

Accordingly, and as the Claimant alleges, albeit not entirely conclusively and without drawing the due consequences therefrom, the said DTC – in particular its article 4 – comes precisely to regulate these situations of double residence, determining, for purposes of the said DTC, which of the countries should be considered as the country of residence.

Here, by its importance, it will be important to reinforce some basic concepts.

The first is that the determination of residence in accordance with and for the purposes of the DTC presupposes that the person in question – the Claimant – is resident in one or both countries.

That is, this means that the Claimant will have to be a fiscal resident of, at least, one of the countries in question, in accordance with their respective internal legislation.

The second is that, for purposes of application of the DTC, the person may only be considered resident of one country.

That is, the person in question – the Claimant –, for application of the DTC, will have to be resident of one of the contracting states and may only be resident of one of the contracting states.

It is, thus, for this reason that the aforementioned article 4 of the DTC provides various tie-breaking criteria for situations in which both contracting states consider – as is here the case – the person as resident in accordance with internal legislation.

Thus, having to determine, for purposes of application of the DTC, a state of (prevailing) residence, and traversing the various subsections of number 2 of the said norm, one will easily conclude that, in particular at the time of receipt of the income in question, it was with France that the Claimant had "(...) the most closely connected personal and economic relations (...)", being also there that he had, at the date of the facts, a permanent residence at his disposal.

In these terms, in the confrontation of the two national tax norms – Portuguese and French – regarding the fiscal residence of the Claimant, should, for purposes of the DTC, the French residence be considered prevailing.

And let it not be said, as the Respondent wishes, that such reasoning is, in itself, incompatible and incoherent.

For residence for domestic purposes should not be confused – cannot be confused – with residence for conventional purposes. As is well noted in the said article 4, the reference to residence there contained is only valid for purposes of the said DTC.

As such, it may well be that a person is resident in Portugal under internal law, not being so under any DTC celebrated by Portugal, and without losing the status of resident in Portugal, namely for purposes of the non-habitual resident regime.

To argue that fiscal residence in Portugal, determined in accordance with article 16 of the Personal Income Tax Code, prevents consideration of another residence under the DTC implies an ill-adjusted interpretation of the rules governing the DTC, in the same way that to argue that residence determined under a DTC affects residence determined under internal law, in the case of Portugal, implies drawing a consequence that does not flow from the law nor from the DTC itself.

Thus, it is perfectly conceivable, especially taking into account the legal provision contained in article 16 at the time of the facts, that a person could be considered as a fiscal resident in two countries simultaneously, with one residence prevailing, to the natural detriment of the other, for purposes of the said DTC.

However, contrary to what the Claimant appears to do, the reasoning cannot stop there. In fact, and as has been said, and here is reiterated, the determination of residence in France, to the detriment of Portugal, for purposes of the DTC, does not prejudice that the Claimant continues to be considered a fiscal resident in Portugal for purposes of internal legislation.

Accordingly, non-subjection to tax of the income in question, in Portugal, will still depend on demonstrating that, under the terms of the DTC, such income could not be taxed in Portugal.

Now, having reached this point, and without prejudice to the very interesting question of qualification of the income at issue here that could be raised, being a matter of a resident in France (albeit only for purposes of the DTC), who earns income from France, nothing more will remain, in this case, than to bring to bear article 23 of the said DTC, in accordance with which (other) income may only be taxed in the state of residence (read, conventional residence).

In this measure, and for the reasons indicated above, without prejudice to the maintenance of the Claimant's tax status for purposes of Portuguese domestic legislation, the same should be considered as resident in France with respect to the period and income at issue here, being that the state with exclusive tax jurisdiction.

In these terms, the answer to be given to the present request for arbitral decision is definitely determined.

Although it is not appropriate, thus, to analyze the other questions posed by this tribunal, it will always be said that, as to the second question posed, and for purposes of what is provided in number 4 of article 81 of the Personal Income Tax Code, it is not sufficient that the income is effectively taxed in the other country – being even that an irrelevant fact – being, on the contrary, essential, to discern whether, under the terms of the DTC in question, the "source country" has tax jurisdiction over it, for which it would be necessary to develop the necessary exercise of qualification of the income at issue here (as indeed flows from the cognitive process pursued by the Respondent).

IV. DECISION

Based on the factual and legal grounds set forth above and, in accordance with article 2 of the LRATM, the Arbitral Tribunal decides:

I) To judge the request for arbitral decision wholly upheld;

II) To annul the Personal Income Tax and compensatory interest assessment with the number 2017..., in the total amount of € 57.389,01 (fifty-seven thousand, three hundred eighty-nine euros and one cent) with the consequent reimbursement of amounts improperly paid;

III) To cancel the bank guarantee provided by the Claimant;

IV) To condemn the Respondent to payment of indemnificatory interest.

VALUE OF THE CASE: In accordance with what is provided in article 306, sections 1 and 2, of the Civil Procedure Code, 97-A, section 1, paragraph a), of the Code of Tax Procedure and Process and 3, section 2, of the Regulation of Costs in Tax Arbitration Proceedings, the value of the case is set at € 57.389,01 (fifty-seven thousand, three hundred eighty-nine euros and one cent).

COSTS: Calculated in accordance with article 4 of the Regulation of Costs in Tax Arbitration Proceedings and Table I attached thereto, in the amount of € 2.142,00 (two thousand, one hundred forty-two euros), to be borne by the Respondent taking into account the merits of the request for arbitral decision.

Frequently Asked Questions

Automatically Created

What is the non-habitual tax resident (RNH) regime and how does it apply to IRS taxation in Portugal?
The non-habitual resident (RNH) regime is a special Portuguese IRS tax regime under Article 16(8) and Article 81 of the IRS Code that allows individuals who become Portuguese tax residents (after not having been residents in the previous five years) to benefit from preferential tax treatment for ten years. For certain foreign-source income from employment, professional services, intellectual property, and pensions derived from high-value-added activities, the RNH regime may provide exemption from Portuguese taxation if the income can be taxed in the source country under a double taxation treaty, or is actually taxed there. Income from Portuguese sources may be taxed at a flat 20% rate for qualifying activities. The regime aims to attract qualified professionals, retirees, and entrepreneurs to Portugal by reducing their tax burden on foreign income.
How is fiscal residency determined for foreign nationals under Portuguese IRS rules and international double taxation conventions?
Fiscal residency in Portugal for IRS purposes is determined under Article 16 of the IRS Code. An individual is considered a Portuguese tax resident if they spend more than 183 days in Portugal (consecutive or interpolated) in any 12-month period beginning or ending in the relevant tax year, or if they have a habitation in Portugal that suggests an intention to maintain it as their habitual residence. For foreign nationals, the determination involves analyzing physical presence, property ownership, family ties, and the center of vital interests. When conflicts arise with other countries claiming tax residency, double taxation conventions (such as the Portugal-France treaty) apply tie-breaker rules based on: permanent home availability, center of vital interests (personal and economic relations), habitual abode, and nationality. Tax authorities examine documentation including residency certificates, property registration, employment contracts, and movement records to establish the residency date and status.
Can a taxpayer challenge an IRS tax assessment through CAAD arbitration proceedings in Portugal?
Yes, taxpayers can challenge IRS tax assessments through CAAD (Centro de Arbitragem Administrativa) arbitration proceedings under the Legal Regime for Arbitration in Tax Matters (RJAT - Decree-Law 10/2011). This alternative dispute resolution mechanism allows taxpayers to contest tax acts including IRS assessments, decisions on administrative complaints, and other tax authority determinations. The arbitral request must be filed within the legal deadline (generally within 90 days of notification or after administrative complaint procedures). CAAD arbitration offers a faster alternative to judicial courts, with decisions typically rendered within six months. Taxpayers must provide a bank guarantee or pay the disputed amount to suspend enforcement. The procedure follows the RJAT rules, allowing written submissions, witness testimony, and hearings. Arbitral decisions are binding and equivalent to court judgments, subject only to limited appeals on procedural grounds to the Court of Appeal.
What happens when a request to expand the scope of a CAAD arbitral claim exceeds the single arbitrator tribunal threshold under Article 5 of RJAT?
Under Article 5 of RJAT, single-arbitrator tribunals have jurisdiction over tax disputes with a value up to €10,000 (later increased to €30,000). When a claimant requests to expand the scope of an arbitral claim and the total value exceeds this threshold, the single arbitrator loses competence and a three-arbitrator panel becomes necessary. In such situations, the arbitrator must notify the claimant of the jurisdictional issue and request clarification on whether they intend to maintain the expanded claim. If the claimant confirms the expansion, the case must be transferred to a collective tribunal or the claimant must withdraw the expansion request. As seen in this decision, when the claimant initially sought to add a €17,697.74 assessment to the existing €57,389.01 claim, the arbitrator identified that the combined value would exceed single-arbitrator jurisdiction and convened a hearing to address this issue. The claimant ultimately withdrew the expansion request to maintain the proceedings before the single arbitrator, preserving jurisdictional competence.
How does international double taxation affect IRS liability for French nationals residing in Portugal?
International double taxation occurs when two countries assert taxing rights over the same income earned by the same taxpayer in the same period. For French nationals residing in Portugal, the Portugal-France Double Taxation Convention (based on the OECD Model) determines which country has primary or exclusive taxing rights over specific income types. Employment income is generally taxable in the residence state unless performed in the other state. Pension income follows specific treaty rules. Investment income (dividends, interest, capital gains) has shared or limited taxation rights. When France has taxing rights and Portugal also asserts residence-based taxation, Portuguese IRS liability may be reduced through: (1) the exemption method (income exempt in Portugal if taxable in France under the treaty), particularly applicable under the RNH regime; or (2) the credit method (Portuguese tax reduced by foreign tax paid). The taxpayer must demonstrate that income was actually taxed in France and qualifies for treaty relief. Proper documentation includes French tax returns, payment proof, tax residency certificates, and income source evidence. Incorrect application of treaty provisions or RNH rules can result in double taxation or disputes requiring arbitration.
