International Tax 2026

PORTUGAL Trends and Developments Contributed by: Tânia de Almeida Ferreira, CCA Law Firm

Outlook: Strengthening Portugal’s equity incentive regime Portugal’s regime is an important policy signal, but its effectiveness as a competitiveness tool will likely depend on further refinement – particularly greater functional neutrality across equity instruments, a reassessment of first-year access outside the startup route, and clearer administrative guidance to reduce controversy and ensure predictable implementation in cross-border and fast-growth scenarios. Reduced VAT Rate on “Moderately Priced” Housing Construction and Rehabilitation: Policy Intent and Market Implications (Portugal) Portugal’s 2026 housing tax package includes an ena - bling framework to extend the reduced VAT rate (6%) to construction and rehabilitation works ( empreitadas ) relating to residential assets, alongside a partial VAT refund mechanism for individuals building their own primary home. Legislative scope and affordability caps The reduced-rate measure is conditional on “moder - ate” affordability limits, with the rent capped at 2.5× the 2026 statutory minimum monthly wage and the sale price capped at the upper threshold of the sec - ond Property Transfer Tax (IMT) bracket. On the numbers, this mechanism is intentionally index-linked (and therefore not perfectly static year- on-year). The 2026 minimum monthly wage is EUR920 and, therefore, the rent cap implied by the authorisation is EUR2,300/month, being the upper limit of the second bracket of EUR660,982. Timing and “operational readiness” (a key market issue) A practical point for sponsors and developers is that policy approval does not automatically translate into Day 1 operability. Market-facing analyses continue to note that, in early 2026, the reduced-rate construction measure is not yet fully operational, pending comple - tion of legislative/implementing steps (and, in prac - tice, interpretative guidance).

As a result, the regime is, in practice, most straight - forwardly compatible with option-type structures, and it is materially less clear how it should apply to direct share grants or modern equity instruments frequent - ly used internationally (eg, RSUs), where there may be no exercise price and where the economic event is driven by vesting/delivery mechanics rather than option exercise. This drafting choice reduces flexibility for startups and groups seeking alignment with stand - ard international remuneration tools and increases the scope for interpretative controversy. Timing constraints: first-year flexibility is limited to the “startup route”, leaving a gap for newly incorporated non-startups The preferential regime allows the startup condition to be met in the year of plan approval where that is the company’s first year of activity, but this carve-out is limited to the startup route. For other eligible issuers (eg, SMEs or “innovation” entities), the law remains tied to the year prior to plan approval, which can make the regime unavailable for plans approved in the incor - poration year. This asymmetry is not merely theoretical: the Por - tuguese Tax Authority (PTA) explicitly confirms in a binding ruling that, outside the startup route, a plan approved in the same year the company was incor - porated cannot satisfy the “previous year” SME con - dition. From a policy perspective, this is difficult to reconcile with how early-stage companies typically rely on equity incentives from inception, and is fertile ground for disputes in borderline cases. Litigation and compliance risk: definitional thresholds, valuation, and corporate governance exposure The regime concentrates litigation and compliance risk around issuer eligibility tests (with potential cliff effects), valuation and timing mechanics tied to option exercise and disposal, and corporate governance exposure, as the granting entity may become subsidi - arily liable for Personal Income Tax (PIT) if it confirms eligibility (or fails to reply within the statutory deadline) and the conditions are later found not to be met.
