IGF Reads Portugal's Non-Habitual Residents Regime at €1.74 Billion in 2024 — Beneficiary Count Triples to 128,958, Fiscal Cost Climbs 181% Since 2019 and 254 Control Situations Across 71 Taxpayers Walk Into the AT's Risk File

The Inspecção-Geral de Finanças (IGF) has homologated an audit — published in detail on Tuesday by ECO — that reads Portugal's Regime dos Residentes Não Habituais (RNH) at a €1,741 million fiscal cost in 2024, against €619.7 million in 2019 — a 181% climb across five years and a number that now sits inside the State Budget's annual Despesa Fiscal annex as one of its largest single-instrument lines. The beneficiary count has more than tripled across the same window — from 41,229 registered NHR taxpayers in 2019 to 128,958 in 2024 — and the IGF inspectors have flagged 254 control situations across 71 taxpayers for evidence of non-compliance with the cinco anos anteriores prior-residency requirement that anchors the regime. The audit was homologated on 29 April 2026 by Secretária de Estado dos Assuntos Fiscais Cláudia Reis Duarte, and the Autoridade Tributária (AT) has accepted the IGF's recommendations to build a specific risk-management strategy around the file.

Reading the Fiscal Cost

The €1.741 billion 2024 print is the largest the NHR regime has ever recorded, and the trajectory across five years is steep: €619.7 million in 2019, climbing across every intermediate year, landing at the 2024 number that the IGF audit now formalises. The growth is not driven by a tax-rate change — the headline 20% flat IRS rate on Portuguese-source actividades de elevado valor acrescentado and the exemptions on foreign-source pensions and most foreign-source income have moved only marginally over the period — but by the volume of taxpayers entering the regime. The 41,229 → 128,958 beneficiary count is the operative variable, and the IGF's reading is that the underlying inflow was driven less by Portuguese fiscal generosity than by the relative tightening of competing European regimes (Spain's impatriado, Italy's impatriati, the Netherlands' 30% ruling) over the same window.

The IRS Revenue Side

The IGF audit pairs the cost number with the revenue line: IRS receipts from NHR taxpayers ran at €275.27 million in 2019 and climbed to €788.62 million in 2023 — a 186.5% increase that broadly tracks the fiscal-expenditure growth across the same window. That symmetry is the kernel of the regime's defenders' case: the cost-revenue ratio has held roughly stable across the inflow cohort, meaning the marginal NHR beneficiary is delivering IRS revenue at a rate not materially below the cost of the exemptions they consume. The IGF does not contest the framing, but flags that the 2024 revenue figure — not yet closed at the time of homologation — will be the determinative test of whether the ratio holds at the new volume.

The 254 Control Situations

The compliance finding sits at the centre of the AT's response. IGF inspectors identified 254 control situations relating to 71 taxpayers where the documentary record showed evidence of non-compliance with the cinco anos anteriores rule — the requirement, set out in the regime's enabling legislation, that a taxpayer was not a Portuguese tax resident in any of the five tax years preceding their enrolment in the NHR scheme. The IGF's reading is that the AT's existing risk-management infrastructure for the regime has been calibrated to identify rate-application errors rather than residency-history fraud, and that a substantive share of the 71-taxpayer cohort would have been caught earlier under a tighter inbound-residency check. The audit's headline recommendation is the creation of a specific control and risk management strategy for the NHR regime, and the AT has confirmed implementation measures are underway.

The Transitional Window

The regime itself was closed to new entrants by Lei n.º 82/2023 (Orçamento do Estado para 2024), with a transitional registration window for taxpayers who could prove residency-establishment steps taken before 1 January 2024; the final transitional registration deadline lapsed on 31 March 2025. Taxpayers registered before 1 January 2024 retain their NHR benefits for the full ten-year exemption period. Taxpayers who became Portuguese tax residents during 2024 under the transitional rules can access NHR benefits through 2033. The tail of the regime — and the fiscal-expenditure line the IGF audit measures — therefore runs out to roughly 2035 on a steady-state assumption, and the AT's tightened control routines will operate across that entire tail.

What It Means for the Expat Cohort

For the foreign-resident population already inside NHR, the IGF audit changes the operating expectation rather than the underlying entitlement. The 10-year exemption window is contractual under the regime's grandfathering rules and does not move on an IGF recommendation. What does move is the AT's audit posture: taxpayers in the 71-name cohort, and any subsequent files the AT walks through the new risk-management routine, will face documentary scrutiny on the five-year prior-residency rule that older NHR registrations did not encounter at the inflow gate. The practical advice line — keep the five-year non-residence documentary chain intact, including tax-residency certificates from the prior jurisdiction and clear evidence that Portuguese stays before the NHR start date did not cross the 183-day or habitual residence thresholds — has become materially more important than it was when the regime was still open.
