Quick answer: Legitimate tax planning in Portugal is the constitutionally recognised right of a taxpayer to organise their activity through the legal form that produces the lowest tax burden, provided that form genuinely reflects the underlying economic substance. The line that separates it from abusive tax avoidance is set out in Article 38(2) of the General Tax Law (Lei Geral Tributária — LGT), which contains Portugal’s General Anti-Abuse Rule (Cláusula Geral Antiabuso, or CGAA): a structure becomes abusive when it is essentially or principally directed at obtaining a tax advantage contrary to the spirit of the law, without autonomous economic substance.
The CAAD arbitration ruling, published in April 2026, which ordered Portuguese television presenter Manuel Luís Goucha to pay an additional tax assessment of €1.17 million, has brought the topic back to the centre of public debate regarding legitimate tax planning in Portugal. But the case has been read, in some commentary, as if the use of a corporate vehicle by an individual were, in itself, suspect. It isn’t. There is a structural argument, anchored in the Portuguese Corporate Income Tax Code itself, that has been left out of the discussion and is worth recovering.
The Goucha case in 60 seconds
The presenter incorporated a commercial company and assigned to it, free of charge, his image rights and the right to exploit them. From that point on, the entities that hired him entered into contracts with the company, and the income was taxed under Portuguese Corporate Income Tax (IRC) rather than Personal Income Tax (IRS).
The Portuguese Tax and Customs Authority (Autoridade Tributária — AT) inspected the structure, concluded it was a “shell company” with no resources of its own and entirely dependent on the presenter’s personal performance, and triggered the General Anti-Abuse Rule (CGAA). The Administrative Arbitration Centre (CAAD) sided with the tax authority, with one dissenting arbitrator, leaving the door open for appeal. Only the 2019 financial year was at stake: €670,000 in tax and €500,000 in compensatory interest.
The factual matrix matters: the tribunal did not condemn the existence of the company, it condemned the specific way it had been set up (free assignment of image rights, absence of operational structure, indissociability between the service provided and the person of the presenter).
What is legitimate tax planning in Portugal, exactly?
Legitimate tax planning (also referred to as tax planning intra legem) is the exercise of a faculty recognised by Portuguese law. No taxpayer is obliged to choose the most expensive route. This freedom rests on three pillars:
- Constitutional — the freedom of private economic initiative (Article 61(1) of the Portuguese Constitution — CRP) extends to the right to structure one’s activity through whichever legal form one considers most appropriate, including a company, even a single-shareholder one.
- Tax law — the taxation of “businesses” set out in Article 104(2) CRP covers both individual and corporate enterprises. Category B of the IRS itself presupposes economic activity, classified under Article 151 of the Personal Income Tax Code (CIRS).
- Systematic — both the IRS (Articles 28 et seq.) and the IRC (Articles 86-A and 86-B) contain simplified taxation regimes. In IRC, the legislator sets a coefficient of 0.75 for “professional activities specifically listed in the table referred to in Article 151 of the Personal Income Tax Code”, the same coefficient as in the simplified IRS regime.
This last point is decisive and deserves a section of its own.
The argument that’s been missing: what the simplified IRC regime tells us
Article 86-B(1)(b) of the IRC Code applies the 0.75 coefficient to “income from professional activities specifically listed in the table referred to in Article 151 of the Personal Income Tax Code” when earned by companies subject to IRC with annual gross revenue up to €200,000. The symmetry is unmistakable: the same threshold and the same coefficient as in the simplified IRS regime [Article 31(1)(b) CIRS].
What does this parallelism tell us?
- The legislator expressly admits that activities typically performed by individuals (doctors, lawyers, accountants, architects, artists, performers, every profession listed in Article 151) may be carried out through a company subject to IRC.
- More than just admitting it, the legislator establishes a dedicated tax regime for these small-scale companies, setting a coefficient identical to that applied to individuals. At this level, there is no hierarchy between the two forms of organisation.
- If the legislator considered the corporate exercise of these activities to be inherently suspect or abusive, it would not have created a simplified regime designed precisely for that scenario.
There is more: these companies are not subject to fiscal transparency under Article 6 of the IRC Code (which generally applies to professional partnerships meeting specific requirements). In other words, the system structurally accepts non-transparent companies, owned by individuals, billing for professional services and taxed under IRC, followed, where applicable, by taxation on dividend distribution.
The consequence is significant: save for borderline cases, it is not consistent with the spirit of the system to characterise the incorporation of a company by an individual as artificial merely because there is a tax differential between IRC plus dividends and IRS Category B. That differential is precisely what the legislator knows about, accepts, and regulates.
The General Anti-Abuse Rule (CGAA): what Article 38(2) LGT actually says
The CGAA allows the Portuguese tax authority to disregard legal acts or transactions for tax purposes when all four of the following elements are present:
| Element | Content |
|---|---|
| Means | Legal acts or transactions, isolated or in series |
| Result | Reduction, elimination, or temporal deferral of tax |
| Intellectual | Essential or principal motivation of a fiscal nature |
| Normative | Tax advantage contrary to the object or purpose of the applicable tax law |
If even one of these elements is missing, the CGAA does not apply. And even when all four are present, its application requires a specific procedure (Article 63 of the Tax Procedure Code — CPPT), with a prior hearing for the taxpayer and authorisation from the head of the tax service. Arbitration case law is consistent: the application of the CGAA imposes a heightened duty of reasoning on the tax authority, which bears the burden of proof for each element.
The 2019 reform (Law no. 32/2019, transposing the EU Anti-Tax Avoidance Directive — ATAD) made the test more demanding for taxpayers; it is now sufficient that the tax advantage be one of the principal purposes (not necessarily the purpose), but it did not abolish the underlying principle of freedom of fiscal management.
The right question isn’t “company or individual?”, it’s “form versus substance”
What distinguished the Goucha case from a legitimate corporate option was not the existence of the company. It was a specific set of facts:
- Free assignment of image rights (no consideration, no economic rationale);
- Absence of autonomous human and material resources within the company;
- Total indissociability between the service provided and the physical person of the presenter;
- No economic activity that did not depend exclusively on the personal intervention of the shareholder.
These elements, taken together, led the tribunal to characterise the company as a “shell”, a form without substance. What is at stake is not the use of a company; it is the disconnect between the legal form adopted and the actual economic facts.
The operational question for the tax adviser is therefore always threefold:
- Does the structure have autonomous economic substance? Is there activity within the company that would exist even without the personal intervention of the shareholder?
- Does the form match reality? Do the contracts, resources, risks, and cash flows genuinely reflect the company as an economic agent?
- Does the structure pass the transparency test? Can it be explained and documented before the tax authority and the courts without needing to be reverse-engineered after the fact?
If the answer to all three is “yes”, we are within the realm of legitimate tax planning, and the incorporation of a company, even a single-shareholder one, even with partly fiscal motivation, is the regular exercise of a right recognised by the legal order.
Borderline cases: when can a company actually be disregarded?
Portuguese arbitration case law has identified recurring red flags:
- Free or token assignment of personal assets (image rights, know-how, client portfolio) to the company.
- No operational structure: no employees, no own equipment, no economic risk borne by the company.
- Total personal indissociability: the service can only be rendered by the shareholder in person, with no value added by the company as an entity.
- Systematic non-distribution of profits, with the company used as a vehicle to fund the shareholder’s personal consumption.
- Absence of any documented non-fiscal rationale for the decision to incorporate.
The presence of one of these elements alone is not enough. It is the coherent accumulation of them that supports the application of the CGAA, and that allows the tax authority to discharge its heightened duty of reasoning.
Practical takeaways for taxpayers and tax advisers
Three operational conclusions:
1. The incorporation of a company by an individual is not, in itself, tax abuse. The Portuguese system expressly admits it, regulates it (including through a simplified regime), and assigns it coefficients equivalent to those applicable to Category B income. Whoever claims otherwise bears the burden of demonstrating, fact by fact, that the specific structure is a non-genuine arrangement.
2. The differential between IRC followed by dividend distribution and Category B IRS is a differential that the legislator knows about and accepts. Choosing one form over the other, even when motivated by tax efficiency, falls within the scope of fiscal management and generally does not constitute an abusive use of legal forms.
3. The real risk is artificiality: structures with no resources of their own, free asset transfers, total personal indissociability. The tax adviser’s job is to design the structure with substance and document its economic rationale from day one, not to try to justify it when the inspection knocks on the door.
FAQ: Legitimate Tax Planning in Portugal and GAAR
What is legitimate tax planning in Portugal? It is the right of the taxpayer to organise their activity through any legally available form that results in the lowest tax burden, grounded in the freedom of private economic initiative (Article 61(1) of the Portuguese Constitution) and in the freedom of fiscal management. It requires compliance with the law and consistency between legal form and economic substance.
What is the General Anti-Abuse Rule (CGAA) in Portugal? The CGAA, set out in Article 38(2) of the General Tax Law, allows the Portuguese tax authority to disregard, for tax purposes, legal acts or transactions essentially or principally directed at obtaining a tax advantage contrary to the spirit of the law, taxing instead according to the economic reality that would have existed without the structure.
Can an individual incorporate a single-shareholder company to bill for their professional activity in Portugal? Yes. The Portuguese legal order expressly permits it, the simplified IRC regime (Articles 86-A and 86-B of the IRC Code) provides a specific 0.75 coefficient for companies carrying out professional activities listed in Article 151 of the IRS Code. The question is whether the company has autonomous economic substance.
What is a “shell company” for the Portuguese GAAR? It is a company with no human or material resources of its own, whose activity depends exclusively on the personal intervention of the shareholder and which has no economic rationale beyond reducing taxes. The Goucha case is a recent textbook example.
What’s the difference between tax planning, tax avoidance, and tax evasion under Portuguese law? Tax planning (legitimate, intra legem) is the choice between legal alternatives that produce a lower tax burden. Tax avoidance is obtaining a tax advantage through formally lawful means that nevertheless contradict the spirit of the law — this is the typical territory of the CGAA. Tax evasion is a direct breach of tax law and carries criminal sanctions.
Does the CGAA apply automatically? No. Its application requires a specific procedure (Article 63 of the Tax Procedure Code), a prior hearing for the taxpayer, authorisation from the head of the tax service, and rigorous reasoning by the tax authority, which bears the burden of proving each of the four elements of the rule.
Is there a real risk of compensatory interest? Yes, and it can be heavy. In the Goucha case, compensatory interest accounted for around 43% of the total assessment (€500,000 of €1.17 million). Since 2019, compensatory interest owed as a result of the application of the CGAA has been further increased by 15 percentage points.
Conclusion: Plan, yes. Artificialise, no.
The Goucha case did not close the door to legitimate tax planning. It did not reverse the constitutional rule of economic freedom. It did not repeal the simplified IRC regime for small-scale companies. What it did was reaffirm a boundary that already existed: legal form must follow economic substance.
In a state governed by the rule of law, the taxpayer can, and should, plan. But good tax planning is what can be explained by the law, sustained by substance, and survives the transparency test. Those who work on the right side of that line have the entire tax system protecting them. Those who cross it expose themselves to additional assessments that, with interest, can approach double the tax originally saved.
