Pillar Two Compliance: Model 62, 63 & 64 Filing Obligations Live

The Portuguese Tax Authority (AT) has launched the complete Pillar Two compliance suite for fiscal year 2025. Model 62 (Registration Declaration) opened in early November 2026 with a 31 December 2026 deadline, requiring MNE groups above €750m revenue to register constituent entities, identify the UPE, and declare IIR/UTPR applicability. Model 63 (GIR/Global Information Return) follows the OECD GloBE schema with real-time XML validation, due 15 months after year-end (31 March 2027 for calendar groups), though early filing is encouraged. Model 64 (Top-up Tax Declaration) captures final liability after IIR, UTPR and QDMTT, with payment due 31 December 2026. The AT provides pre-filling from CbCR data and a homologação test environment. Penalties reach €500/day up to €25,000 per model. Groups must coordinate cross-border data consistency and use qualified digital certificates.

2026 IRS Rate Reform: Bracket Reduction & Solidarity Surcharge Elimination

Decree-Law 212/2026 (published 4 November 2026, retroactive to 1 January 2026) restructures personal income tax from nine to seven brackets, lowering marginal rates across the first six brackets (13%–35% up to €38,790). The top rate falls from 48% to 45%, and the 2.5% solidarity surcharge on income >€80,882 is abolished. Minimum subsistence rises to €11,480, general deduction to €4,300, and dependent deductions increase (€900/1st, €1,050/2nd, €1,200/3rd+). The measure benefits ~4.2m taxpayers (70% of filers) with average savings of €150–€450; high earners gain €1,500+. Employers must recalculate January–October withholdings and adjust November payroll, submitting corrected DMR by 20 December 2026. Withholding tables for 2027 payroll will reflect new rates.

VAT Group Regime Fully Operational via Finance Portal

Ofício-circulado 90088/2026 (28 October 2026) activates the VAT Group regime (Law 62/2025) through the Portal das Finanças ‘Change of Activity’ declaration. Closely linked entities (>50% voting rights/control, shared management, economic interdependence) may now apply to be treated as a single taxable person: intra-group supplies are disregarded, a single periodic return (Modelo 22) is filed by the group representative (jointly/severally liable), and compliance costs and cash-flow delays are eliminated. The regime excludes simplified retailers and cash-accounting taxpayers unless they opt out. Groups may apply anytime; effectiveness begins the next calendar quarter. The representative must retain intra-group transaction records for 10 years. Penalties include €750–€22,500 for non-filing, joint liability for debts, and retroactive exclusion if criteria cease. AT audits within 24 months of formation.

Periodic VAT Return Overhaul: New Layout & FAQ Guidance

The AT released a comprehensive FAQ (early November 2026) for the revised Periodic VAT Return (Declaração Periódica do IVA), mandatory since January 2026 periods under Portaria 112/2026 transposing EU Directive 2020/284. Key changes: disaggregated exempt operations (with/without deduction right), separate OSS/IOSS distance-sales reporting, enhanced reverse-charge breakdown, voucher treatment per Directive 2016/1065, call-off stock and triangular transaction coding, and alignment with ViDA real-time reporting proposals. Incomplete/incorrect returns face rejection and penalties (€150–€3,750). Taxpayers must validate SAF-T (PT) exports against schema v1.04_01 and maintain real-time e-Fatura invoice communication. Monthly filers’ first affected return was due 10 March 2026; quarterly by 15 April 2026.

Fuel Supply Chain: Expanded VAT Reverse Charge & Traceability Mandates

Law 65/2026 (5 November 2026) transposes EU Directives 2020/285 (small enterprise VAT exemption) and 2022/542 (VAT rates) while introducing anti-fraud measures for ~2,500 fuel resellers. VAT: mandatory reverse charge for B2B fuel supplies between taxable persons (effective 1 January 2027) covering blended fuels/biofuel mixtures. CIEC: ISP exemption thresholds for biofuels/synthetic fuels aligned with RED II sustainability criteria. Traceability: real-time electronic reporting via upgraded SIGP 2.0 integrating customs (STADA) and e-invoicing (SPED), plus unique fiscal markers for all automotive fuels. Penalties up to €250,000 per infringement for non-registration, marker tampering, or reporting failures. SMEs below €14,500 threshold gain simplified compliance. Migration deadlines: SIGP 2.0 by 31 March 2027; fiscal markers by 30 June 2027; transitional paper tracking until 31 December 2026.

Cross-Border VAT Fraud Crackdown: Operação Hermes

The AT announced participation (7 November 2026) in Operação Hermes, a EUROPOL-coordinated multi-state investigation targeting intra-community VAT fraud networks using carousel/MTIC schemes. Customs and tax units leveraged Eurofisc and VIES for real-time data sharing, identifying false invoicing and shell companies evaporating VAT liabilities. High-risk sectors: electronics, telecommunications, carbon credits. No new legislation, but signals intensified enforcement under EU VAT Directive 2006/112/EC and Mutual Assistance Regulation 2018/1541. MNEs with complex supply chains must audit intra-community acquisition/dispatch documentation, verify VIES registrations, ensure SAF-T (PT) real-time reporting, and conduct partner due diligence. AT may issue follow-up information requests; penalties up to €225,000 for serious fraud plus criminal liability.

OE2027 Measure: Increased IRS Deduction for Large Families

Parliament approved (28 October 2026) an OE2027 amendment raising the specific IRS deduction for households with three or more dependents from €726 to €900 per dependent annually (Article 78-C CIRS). For three children, annual tax saving rises from €2,178 to €2,700. Applies to 2027 tax year (2028 Modelo 3 filing). Dependents must be under 25, in education or disabled. AT will update e-Fatura household validation and IRS Automático logic by December 2026. Families must ensure dependents’ NIFs are correctly linked. Estimated cost: €85m/year, offset by reduced corporate R&D credit ceiling (Article 32 IRC).

Portugal Advocates EU Common External Tariff Reduction to 10%

Foreign Minister Paulo Rangel confirmed (29 October 2026) Portugal will push at EU Council for lowering the common external tariff ceiling to 10%, benefiting automotive components, textiles, and agri-food where MFN duties often exceed 10%. The position aligns with the Commission’s Common Commercial Policy review and ‘Trade for All’ strategy. High tariffs disproportionately affect peripheral, trade-open economies. Requires unanimous Council + EP consent; realistic timeline 2028–2029. Portugal also seeks simplified customs procedures for SMEs under ‘Customs Union 2030’ (simplified declarations, deferred payments), complementing the national ‘Exportar Mais’ programme. Extra-EU traders should monitor Customs Tariff Regulation amendment and prepare supply-chain cost recalculations.
