At a glance: The Portugal ex-residents tax regime, widely known as the Programa Regressar, excludes 50% of employment and self-employment income from tax for individuals who move their tax residence back to Portugal, subject to conditions. One of those conditions is that the taxpayer must not have been resident in Portugal in the years immediately before the return. On 22 June 2026 the Supreme Administrative Court (Supremo Tribunal Administrativo, STA) published Acórdão de Uniformização de Jurisprudência n.º 12/2026, which settles how that condition is read: “residence” means tax residence as defined in Article 16.º of the IRS Code, not mere physical presence. A few months spent in Portugal in a relevant year does not, by itself, bar access to the regime.
The Portugal ex-residents tax regime has been one of the more attractive incentives for the Portuguese diaspora since 2019, and Madeira’s large emigrant community is squarely within its intended audience. Its practical value, however, depends on how the eligibility conditions are interpreted, and on that point the Tax Authority (Autoridade Tributária, AT) and several arbitration tribunals had been applying a reading that narrowed the regime considerably. The STA has now corrected that reading in a binding uniformising decision.
What the Portugal ex-residents tax regime is
The regime sits in Article 12.º-A of the IRS Code (Código do IRS, CIRS). In its original wording, introduced by the 2019 State Budget (Lei n.º 71/2018, of 31 December), it excluded from taxation 50% of dependent-work income (Category A) and business and professional income (Category B) for taxpayers who became tax resident in Portugal in 2019 or 2020, provided that they:
- had not been considered resident in Portuguese territory in any of the three preceding years;
- had been resident in Portugal at some point before 31 December 2015; and
- had their tax situation regularised.
A taxpayer who applied for non-habitual resident status could not also use the regime.
The regime was later renewed. Under the 2024 State Budget (Lei n.º 82/2023, of 29 December) it applies to individuals who become tax resident in 2024, 2025 or 2026, requires that they were not resident in Portugal in any of the five preceding years, caps the 50% exclusion at EUR 250,000 of income per year, and runs for five years from the year of return. The entry window for the current iteration closes on 31 December 2026. The dispute the STA resolved arose under the original three-year wording, but the interpretive principle it sets reaches the later versions, because each iteration uses the same statutory architecture and the same reference back to Article 16.º.
The condition that was in dispute
The friction was concentrated on the non-residence condition. The original wording required that the taxpayer “had not been considered resident in Portuguese territory in any of the three preceding years”. The question was what “resident” means in that sentence.
The AT, and some arbitration tribunals at the Centro de Arbitragem Administrativa (CAAD), were reading it in an everyday sense: if the taxpayer had been physically in Portugal for any part of one of those years, or had earned income there during it, that year counted as a year of residence and the regime was refused. On that reading, an emigrant who left mid-year to take up a post abroad would be treated as resident for the whole of the departure year, and the year would disqualify the return.
In the case before the STA, the taxpayer had worked in Portugal as an engineer until May 2017, accepted a post in Spain, moved there with his family in late May 2017, and notified the AT of the change of residence to Spain on 1 July 2017. He returned to Portugal in 2020 and sought the ex-residents regime. The AT refused, on the sole basis that he had been resident, if only partially, in 2017, which fell within the three preceding years.
Two arbitration decisions pointing in opposite directions
The recourse turned on a conflict between two CAAD decisions on materially identical facts.
The decision under appeal (Processo n.º 271/2025-T, 15 October 2025) denied the regime. It treated the taxpayer as resident in Portugal in 2017 because he had worked and remained there for part of the year, without applying the day-count and habitual-residence tests of Article 16.º CIRS.
The decision relied on as the contrasting authority (Processo n.º 101/2023-T, 6 November 2023) reached the opposite result on a near-identical set of facts, a 2017 departure to take up work in the Netherlands followed by a 2020 return. It held that there was no tax residence in 2017 because the taxpayer had not remained in Portugal for more than 183 days and had not kept housing in conditions revealing an intention of habitual residence. The non-residence condition was therefore satisfied.
The STA accepted that this was a genuine conflict of decisions on the same fundamental question of law, and that the conflict justified a uniformising ruling.
What the STA decided
The Pleno of the Tax Litigation Section uniformised the case law as follows: the concept of residence relevant to the condition in Article 12.º-A(1)(a) CIRS, that the taxpayer “had not been considered resident in Portuguese territory in any of the three preceding years”, is the concept fixed by Article 16.º of the same Code.
In other words, eligibility is tested against the statutory definition of tax residence, not against any presence in the country. Under Article 16.º, a person is resident in a year only if they remain in Portugal for more than 183 days in any twelve-month period, or keep a dwelling in conditions that suggest an intention to hold it as a habitual residence. A taxpayer who falls below those thresholds in a given year is not resident in that year, even if they spent some time in Portugal.
The Court granted the appeal, annulled the decision under appeal, and ordered costs against the AT.
The reasoning, step by step
The STA built its conclusion on three points.
First, in tax law “residence” is a technical legal concept, not a colloquial one. Article 11.º of the General Tax Law (Lei Geral Tributária) requires that terms used in tax rules carry the meaning that tax law gives them. Within the IRS Code, residence is defined in Article 16.º, and that definition governs.
Second, the words the legislator chose point to a legal qualification. The condition does not say the taxpayer must not “have resided” in the relevant years; it says they must not “have been considered resident”. The word “considered” directs the reader to a legal characterisation under the statutory criteria, as the rules of interpretation in Article 9.º(3) of the Civil Code confirm. Had the legislator meant any ordinary presence to count, it would not have used that word.
Third, partial presence is not enough on its own. The fact that the taxpayer was in Portugal for part of 2017, for a period not exceeding 183 days, does not by itself make him resident for the purpose of excluding the regime. To refuse the benefit on the strength of that year, the AT would have had to show that the Article 16.º criteria were met, more than 183 days, or habitual-residence housing. It did not, so it could not deny the regime on that basis. The Court also noted the related rules that the tax year coincides with the civil year (Article 143.º CIRS) and that a taxpayer’s status is assessed by reference to the last day of the year (Article 13.º(8) CIRS).
What it means in practice
For returning emigrants, the threshold question is no longer whether they set foot in Portugal during one of the relevant years. It is whether, in that year, they met the Article 16.º tests. An individual who stayed in Portugal for up to 183 days and kept no dwelling pointing to habitual residence is not, on that ground alone, shut out of the regime. Some published commentary still describes any partial-residence year as disqualifying; after this ruling, that description is no longer safe.
For the AT, the naturalistic reading is closed. It can no longer refuse the Programa Regressar on the logic that “the taxpayer was here in year X, so he was resident in one of the relevant years”. If it wants to treat a year as a year of residence, it must invoke and prove the Article 16.º criteria.
For tax arbitration, the uniformised reading binds future CAAD decisions on the regime. Arbitration awards that rest on the formal “any presence equals residence” reading will be out of step with the STA’s settled case law.
There is also a look-back dimension. Returning residents who were refused the regime, or who did not claim it, on the basis of the restrictive reading may have grounds to revisit the position, subject to the applicable review and limitation rules. Each case turns on its own facts and on the time elapsed since the assessment, so the route and the prospects need to be checked individually.
The Madeira angle
The ex-residents regime is national law and applies in the Autonomous Region of Madeira on the same terms as on the mainland. For Madeira the regime matters disproportionately, because the Region’s diaspora is large and long-established, with significant communities in Venezuela, South Africa, the United Kingdom, the Channel Islands and elsewhere, many of whom return or consider returning. The 50% exclusion operates on the taxable base; the remaining taxable income is then taxed under the Madeira regional IRS brackets, which differ from the mainland schedule. The interaction of the exclusion with the regional rates, and the coordination with the entry deadline of 31 December 2026 for the current iteration, are the points where planning adds value for a returning Madeiran taxpayer.
Practical takeaways
- The Portugal ex-residents tax regime excludes 50% of employment and self-employment income from tax, capped at EUR 250,000 per year under the current iteration, for five years from the year of return.
- The STA has confirmed that the non-residence condition is tested against the tax-residence concept of Article 16.º CIRS, not against mere presence in Portugal.
- A year in which the taxpayer was in Portugal for up to 183 days, with no habitual-residence housing, does not by itself disqualify the return.
- The AT must prove the Article 16.º criteria if it wants to treat a year as a year of residence.
- The current entry window closes on 31 December 2026; returns must be planned against that date.
- Refusals based on the old restrictive reading may be worth revisiting, subject to the review and limitation rules.
Where MCS can assist
Madeira Corporate Services advises returning emigrants and their families on access to the ex-residents regime: assessing eligibility against the Article 16.º criteria for each relevant year, documenting the non-residence position, coordinating the timing of the return against the 31 December 2026 entry deadline, and preparing the Modelo 3 return with the regime elected. Where a prior refusal rested on the restrictive reading the STA has now rejected, we can review whether the assessment can still be revisited. We can assist, subject to a review of the residence history, the documentary record, and the assessments in question.
Frequently asked questions
What is the Portugal ex-residents tax regime? It is the regime in Article 12.º-A CIRS, popularly the Programa Regressar, which excludes 50% of employment and self-employment income from tax for individuals who move their tax residence back to Portugal, subject to conditions and, under the current iteration, an annual cap of EUR 250,000 for five years.
What did the STA rule in Acórdão 12/2026? That the non-residence condition (not having been considered resident in any of the relevant preceding years) is assessed using the tax-residence definition in Article 16.º CIRS, not an everyday notion of presence.
Does spending a few months in Portugal in a relevant year disqualify me? Not by itself. If you did not exceed 183 days and kept no dwelling in conditions of habitual residence, that year does not, on its own, bar the regime.
Which years does the non-residence condition cover? Under the original wording it was the three preceding years. Under the current iteration (returns in 2024 to 2026) it is the five preceding years. The STA’s interpretive principle applies to both, because both reference Article 16.º.
Can the Tax Authority still refuse the regime? Yes, but it must invoke and prove the Article 16.º criteria for the year it treats as a year of residence. It can no longer rely on partial presence alone.
Was the regime refused to me in the past? Can it be reopened? Possibly, depending on how the refusal was reasoned and on the time elapsed. Refusals based on the restrictive reading may be worth reviewing under the applicable review and limitation rules.
Does the regime apply in Madeira? Yes. It is national law and applies in Madeira on the same terms; the taxable portion is then subject to the regional IRS brackets.

It reflects the position at the date of preparation and is based on Acórdão STA n.º 12/2026 as published in the Diário da República of 22 June 2026 and on the wording of the ex-residents regime in Article 12.º-A CIRS in its original (Lei n.º 71/2018) and current (Lei n.º 82/2023) forms. Tax rates, thresholds, the annual income cap and the entry deadline move with each annual State Budget and may change. The regime is automatic and elected in the Modelo 3 return; eligibility depends on the facts of each case, including the residence history in the relevant years assessed under Article 16.º CIRS.
