EU Court Removes Portugal’s Transfer Tax Barrier for Share Reorganisations — What Investors Must Know

CJEU ruling rewrites tax rules for real estate in Portugal

On 4 June 2026, the Court of Justice of the European Union handed down a decision that changes how real estate in Portugal is taxed in certain corporate reorganisations. The CJEU in Nova Iberomoldes – SGPS, S.A. v Autoridade Tributária e Aduaneira (Case C‑837/24) held that Portugal’s real estate transfer tax (RETT), when applied to some share-for-share exchanges, conflicts with Council Directive 2008/7/EC (the Capital Raising Directive). This is directly relevant to investors, corporate acquirers, and tax advisers who structure deals around Portuguese property-holding vehicles.

The ruling removes a key fiscal obstacle that has influenced deal design for years. We explain the legal finding, the types of transactions affected, immediate steps taxpayers should take, and what this means for comparable regimes elsewhere in the EU.

What exactly did the CJEU decide?

The court examined whether a Portuguese RETT rule that treats certain acquisitions of shares in companies holding Portuguese property as equivalent to a direct real estate transfer can be applied when those share transfers occur as part of a reorganisation covered by the Capital Raising Directive.

Key legal points the court made:

• The case involved an in-kind share contribution where a newly incorporated holding company received shares in several companies, one of which was a so-called real estate-rich company.
• Under Portuguese law, Article 2(2)(d) of the RETT Code treats the acquisition of at least 75% of the share capital of a company whose assets are more than 50% Portuguese real estate as a transfer of immovable property subject to RETT.
• The CJEU found that such RETT, as applied to the in-kind contribution, is an indirect tax on the raising of capital and therefore falls within the scope of Directive 2008/7/EC.
• The Directive prohibits member states from levying indirect taxes on reorganisation operations defined in Articles 4 and 5(1)(e).
• The court rejected Portugal’s attempts to rely on the Directive’s derogations and dismissed anti-abuse arguments. It said member states cannot apply an automatic tax presumption to all qualifying transfers without actual evidence of abuse.

The practical legal conclusion: RETT cannot be applied to transactions that qualify as reorganisations under the Capital Raising Directive, including the share-for-share contribution at issue.

Which transactions are affected — and which are not?

The ruling focuses on the function and form of the transaction rather than labels assigned by national law. In practice, the CJEU’s decision will be most relevant to these transaction types:

• In-kind contributions of shares where the consideration is shares in the receiving company (share-for-share exchanges or incorporations by contribution)
• Share capital increases accomplished by contributing shares in another company to receive newly issued shares
• Certain intra-group reorganisations where a newly formed company acquires controlling stakes in property-holding entities through share exchanges

Transactions that are less likely to be affected include:

• Ordinary market sales of shares where no reorganisation operation under the Directive is involved — RETT remains available to the tax authority in those circumstances
• Mergers and demergers that already benefit from specific domestic exemptions (for example, Article 60 of the Tax Benefits Statute in Portugal) — in practice these are often already carved out from RETT

Important thresholds and definitions from the judgment to remember:

• 75%: the ownership threshold used by Portuguese law to define when a share acquisition is treated like a property transfer
• 50%: the threshold for a company to be classed as a real estate-rich company, measured by the share of Portuguese immovable property in its assets

Why the decision matters for real estate investment and M&A in Portugal

We have seen practitioners design structures specifically to avoid RETT exposure — either to reduce transaction costs or to enable internal reorganisations. The CJEU ruling removes a predictable tax cost where the transaction meets the reorganisations test under the Directive.

Consequences for buyers and investors:

• Lower transactional friction for intra-group restructurings that use in-kind share contributions rather than asset transfers
• Improved flexibility in deal timing and structure because the RETT tax obstacle is no longer an automatic cost for qualifying reorganisations
• Increased ability to cite EU law in tax disputes where national authorities have assessed RETT on reorganisations

Consequences for deal advisers and tax teams:

• Routine due diligence must now include a legal assessment of whether a transaction falls within the Capital Raising Directive’s protections
• Pricing models for deals that previously assumed RETT will need revision
• For ongoing or historical assessments, taxpayers should consider immediate litigation or administrative challenges, relying on the direct effect of EU law and the CJEU judgment

Practical checklist for advisers, investors and corporates

If you have transactions, disputes, or planning around Portuguese property-holding companies, here is a pragmatic checklist we recommend:

• Identify pending RETT assessments or audits that relate to reorganisation-style share contributions. These can be contested using the CJEU decision.
• For future transactions, determine whether the deal falls within the scope of the Capital Raising Directive’s definition of a reorganisation. If it does, RETT should not be charged.
• Review share purchase agreements and tax indemnities. If sellers were asked to accept RETT-related risks, those allocations may be renegotiated now.
• Coordinate litigation strategy with Portuguese counsel to invoke the direct effect of EU law in national courts and administrative proceedings.
• Document economic substance and governance where relevant; the CJEU rejected blanket anti-abuse presumptions, but targeted abuse allegations supported by evidence remain part of the tax authority toolkit.

We advise tax and deal teams to act quickly on pending assessments. The CJEU’s reasoning gives taxpayers a clear legal lever to obtain refunds or to prevent future RETT levies on qualifying reorganisations.

Wider EU implications — are other countries at risk?

The ruling applies a principle that courts across the EU will find persuasive: the court looks at the objective effect of a tax rather than its domestic title. Several other member states operate regimes that treat transfers of shares in property-holding companies as equivalent to transfers of property for tax purposes.

Countries where comparable rules exist include Germany, Austria, and Spain, among others.
