Court of Justice of the EU Rules Against Portugal's IMT on Corporate Restructuring in the Nova Iberomoldes Reference — Directive 2008/7/EC Trumps the CIMT Levy

The Court of Justice of the European Union (CJEU, Tribunal de Justiça da União Europeia) handed down a reading on Thursday 4 June 2026 that Portuguese tax law cannot levy IMT (Imposto Municipal sobre Transmissões Onerosas de Imóveis, Municipal Property Transfer Tax) on real-estate moves that happen inside a corporate-restructuring operation. The reference was sent up by the Centro de Arbitragem Administrativa (CAAD, Administrative Arbitration Centre) out of the Nova Iberomoldes case — a Portuguese mould-industry holding that challenged an additional IMT assessment issued by the Autoridade Tributária e Aduaneira (AT, Tax and Customs Authority) after an intra-group reorganisation moved properties between affiliates.

Luxembourg pinned the reading to Directive 2008/7/EC, the Council instrument on indirect taxes on the raising of capital. Article 5 of the Directive prohibits Member States from imposing any form of indirect tax on capital-companies restructuring operations — including transfers of assets, exchanges of shares, contributions of branches of activity and mergers. The Court found that the Portuguese Código do IMT (CIMT), in the version pursued by the AT, fell on the wrong side of that bar when it treated real estate inside a restructuring as a taxable onerous transmission and assessed transfer tax on the building's value.

The mechanics on the Portuguese side run through the Código do IMT's Article 2, which lists onerous transmissions of immovable property as the trigger event, and Article 17, which sets the tax base on the property's market value or registered value, whichever is higher. The AT had been applying the levy to property moves that flagged a Conservatória do Registo Predial (Land Registry) transfer line — including the moves that sit inside a Directive-2008/7-protected restructuring. The Nova Iberomoldes reading closes that pipeline. Article 5 of the Directive has direct effect, so the Portuguese taxpayer can rely on it against the AT without waiting for a legislative recast of the CIMT.

The practical consequence for the Portuguese corporate base is wide. Holding-company restructurings, intra-group spin-offs, contributions of business branches to a Newco, and mergers of related entities are the standard tax-neutral toolkit used during succession planning, group simplification and entry of foreign investors. The AT had been treating every such move as an IMT trigger when real estate sat inside the transferred perimeter — at rates that climb from a marginal 1% to a top of 7.5% on urban building values above the IMT scale ceiling. Pending CAAD arbitrations and Tribunal Administrativo e Fiscal (TAF) impugnações that hang on the same question can now be resolved in the contribuinte's favour.

The fiscal cost to municipalities — IMT is a municipal tax whose revenue accrues to the Câmara Municipal in whose perimeter the property sits — is less immediate than it appears. IMT on restructuring assessments has historically been a small share of municipal yield; the volume sits primarily in retail purchases. But on the back-file side, refund claims from corporates that paid IMT under protest on restructuring transmissions, plus interest at the legal rate, will land on the AT in the coming year. The AT has not yet circulated an internal guidance note on how it will close the back-file, but the obligation under EU jurisprudence is clear: refunds must run.

The Government will face the harder downstream question of whether the IMT Code needs a positive carve-out for restructuring operations, or whether the direct-effect reading is enough to immunise restructurings without a legislative fix. The Ordem dos Revisores Oficiais de Contas (OROC, Chartered Accountants Association) and the Associação Fiscal Portuguesa (AFP) have both pushed since 2022 for an express CIMT exemption tracking the EU Directive — a position that now lands with renewed weight.
