Italy Portfolio Dividend Withholding Tax 2026: The Non-EU Parent Trap

ABSTRACT: Law No. 199 of 30 December 2025 — Italy's 2026 Budget Law — restructured the taxation of portfolio dividends, conditioning the 95% exemption on a minimum participation threshold and leaving EU/EEA parent companies with a 1.2% effective withholding tax rate that Italian residents and non-EU parents cannot access on the same terms. The disparity has been labelled reverse discrimination by leading tax scholars, is now under both constitutional and TFEU scrutiny, and creates both a compliance risk and a refund opportunity for UK, US, Canadian and Australian shareholders in Italian companies. This article maps the gap, explains the case law that is already closing it, and sets out the practical steps a non-EU parent should take now.

When your Italian subsidiary pays a dividend, the rate you pay may depend not on your deal but on your postcode

Imagine two corporate shareholders, each holding a 6% stake in the same listed Italian company. One is incorporated in Amsterdam. The other is in London. After 1 January 2026, the Dutch parent pays an effective Italian withholding tax of 1.2% on every euro of dividend. The British parent pays 5% under the Italy–UK Double Tax Convention — more than four times as much. Neither holds enough to trigger a full exemption under the EU Parent-Subsidiary Directive. The only difference between them is that the Netherlands is inside the European Union and the United Kingdom is not. That difference, crystallised by Italy's 2026 Budget Law, is what tax lawyers now call the reverse discrimination problem.

What the 2026 Budget Law actually changed

Law No. 199 of 30 December 2025 (the 2026 Budget Law) amended the tax treatment of intercompany dividends in Italy, amending a regime first introduced by the 2004 corporate income tax reform, which was based on a partial exemption system under which dividends were largely excluded from taxable income.

Before the reform, the position was generous and broadly uniform. Under prior rules through fiscal year 2025, dividends received by resident entrepreneurs generally benefited from a partial exclusion from taxable income equal to 95%, and dividends paid by Italian companies to Italian or EU/EEA companies were effectively taxed at 1.2%, regardless of the size of the holding.

The 2026 Budget Law narrows the scope of this exemption by introducing two alternative eligibility thresholds: participation of at least 5% of the share capital in the distributing company, or a tax book value of the holding of at least €500,000. The participation may be held directly or indirectly. Where shareholdings fall below these thresholds, distributed dividends and realised capital gains will be fully subject to corporate income tax (IRES) and personal income tax (IRPEF).

Although the measure appears primarily aimed at increasing the tax burden on portfolio minority interests — for example, trading investments — its effects also apply to other categories of investors, such as club-deal participants and start-up investors.

One further complication: in a significant follow-up, the Italian government issued Decree Law No. 38 of 27 March 2026, commonly referred to as the "tax decree," which partially restored the pre-Budget Law participation exemption and dividend-exemption framework, applying retroactively from 1 January 2026. The interplay between the Budget Law restrictions and the Decree Law 38/2026 rollback requires careful statutory mapping for every transaction currently in progress.

What is the dividend tax rate for a UK company receiving Italian dividends in 2026?

The answer depends on participation size and the applicable double tax treaty, but it is never as low as 1.2%.

While economic double taxation is prevented in the case of domestic dividend distributions, the same protection does not apply to outbound dividend distributions, except for dividends paid to companies resident in EU or EEA Member States, for which a reduced withholding tax rate of 1.20% applies pursuant to Article 27(3-ter) of Presidential Decree No. 600 of 1973.

A UK company falls outside that provision. Post-Brexit, the United Kingdom is neither an EU Member State nor party to the European Economic Area Agreement. A UK parent receiving dividends from an Italian subsidiary therefore falls back on the Italy–UK Double Taxation Convention. Depending on participation size, the convention rate is typically 5% for substantial holdings and up to 15% for pure portfolio holdings. A US, Canadian or Australian parent company is in the same position, governed by its own bilateral treaty with Italy.

If none of the participation thresholds is met, dividends fall under ordinary taxation rules — generally fully subject to Italian income taxes if received by resident entrepreneurs, or subject to a 26% withholding tax, reducible under applicable tax treaty or domestic exemption provisions for non-resident recipients.

The reverse discrimination problem: why Italian investors are now taxed harder than some foreigners

Here is the structural anomaly that has alarmed tax scholars. The new IRES exemption regime does not affect the taxation of dividends an Italian subsidiary pays to its EU parent company, which under Article 27(3-ter) of Presidential Decree No. 600 of 1973 may still benefit from 95% exemption through the Italian withholding tax at 1.2% reduced rate, regardless of whether the EU parent company would meet the minimum 10% participation threshold.

The consequence is stark. From 1 January 2026, dividends on portfolio shareholdings paid to an EU/EEA parent company not covered by the Parent-Subsidiary Directive would be taxed at 1.2%, whereas the same dividends paid to an Italian resident shareholder would be subject to final withholding tax at the 26% rate. Such disparity creates an instance of reverse discrimination, whereby domestic taxpayers are treated less favourably than cross-border taxpayers. Although EU law does not prohibit reverse discrimination as such, its prevention may be conventionally and constitutionally required.

Unlike in most common-law jurisdictions, where tax legislation affecting resident companies must satisfy a constitutional principle of equal treatment between residents (and where a domestic taxpayer discriminated against compared with a foreign one would have an immediate constitutional remedy), Italy's situation is more complex. Reverse discrimination in EU law is generally a matter for Member States' internal constitutions rather than for the Court of Justice of the European Union. The Italian Constitution — specifically Article 3, enshrining equality before the law — could provide a vehicle for challenge, but the path through the Italian Constitutional Court is slow and uncertain. What is certain is that the disparity exists now, on every dividend payment resolution adopted from 1 January 2026.

Nemo debet esse judex in propria causa — no one ought to be judge in their own cause. The Italian legislature cannot credibly maintain that a rule taxing its own residents more heavily than comparable foreign investors reflects a principled policy choice; it reflects an oversight in the EU law implementation that the 2026 Budget Law failed to cure.

As the political economist Albert O. Hirschman observed, systems under stress produce either exit, voice or loyalty. Italian minority shareholders unable to access the 5% threshold face exactly this trilemma: restructure to exit the unfavourable tax band, challenge the rule through constitutional voice, or accept a cost of loyalty to their existing structure. Non-EU parents face a variant of the same dilemma — but with an additional legal weapon that Italian residents cannot use.

How does Italy's 2026 Budget Law affect non-resident shareholders? The Article 63 TFEU route

The most consequential legal development of 2026 is the consolidation of case law allowing non-EU parent companies to claim the 1.2% rate by invoking the free movement of capital under Article 63 of the Treaty on the Functioning of the European Union (TFEU). This provision is not limited to intra-EU situations; it extends to capital movements between EU Member States and third countries, including the United States, the United Kingdom, Canada and Australia.

In a landmark decision (Judgment No. 93/2026, dated 17 February 2026), the second-tier Italian Tax Court of Abruzzo (Corte di Giustizia Tributaria di secondo grado dell'Abruzzo) confirmed that a US corporation controlling an Italian subsidiary is entitled to a withholding tax refund on dividends. The court ruled that the application of a 5% withholding tax rate under the Italy–United States Double Tax Convention, rather than the 1.2% rate applicable to EU/EEA resident shareholders, constitutes an unjustified restriction on the free movement of capital under Article 63 TFEU. The court upheld the first-instance decision ordering the Italian Tax Authorities to refund the 3.8% excess withholding tax paid on dividends distributed in 2018.

That decision built on earlier first-instance authority. Based on the EU principle of free movement of capital, the Tax Court of first instance of Pescara (Decision No. 509/2024) stated that a US company subject in 2018 to a 5% dividend withholding tax under the Italy–US Double Taxation Treaty had to be treated as an Italian or EU recipient and thus subject to a maximum 1.2% withholding tax.

Crucially, the Italian Court of Cassation (Corte di Cassazione) has now reinforced this line at the highest level. The Italian Supreme Court issued a landmark ruling further consolidating favourable case law for non-resident investors on dividend withholding tax. In Decision No. 4761/2026 (filed on 3 March 2026), the court held that the higher Italian withholding tax applied to outbound dividends, compared with the effective burden borne by comparable Italian corporate recipients, is discriminatory under Article 63 TFEU. The court specifically rejected reliance on "compensatory advantages" — for example, foreign tax credits or other reliefs in the recipient's country of residence — to offset the discrimination.

That last point is decisive for UK and US parents. Italian Tax Authorities had consistently argued that a treaty-rate reduction, combined with a credit in the parent's home jurisdiction, neutralised any discrimination. The Italian Court of Cassation has now closed that argument definitively.

Tax refund claims are nonetheless firmly rejected by the Italian Tax Authority on the basis of a strict and literal interpretation of domestic and international law provisions. A UK or US parent wishing to access the 1.2% rate will need to litigate — but the jurisprudential wind is now firmly in favour of the claimant.

What is the participation exemption threshold for Italian dividends, and what should non-EU parents do now?

The practical matrix is as follows. If a non-EU parent holds at least 10% in the Italian subsidiary and meets the other conditions in Article 27-bis of Presidential Decree 600/73 (implementing Council Directive 2011/96/EU, the EU Parent-Subsidiary Directive), the withholding tax is reduced to zero — but only for EU-resident parents. A UK parent cannot use this route. If the UK parent holds between 5% and 10%, there is a mismatch between the tax treatment applicable to inbound dividends versus outbound dividends paid by Italian entities, as no restrictions were introduced in respect of distributions to EU shareholders pursuant to Article 27, paragraph 3-ter, of Presidential Decree 600/73, meaning EU shareholders continue to be entitled to Italian source-state taxation limited to 1.2% without satisfying the 10% threshold condition.

Four practical actions follow from this analysis.

First, map your current participation. If you hold below 5% and below the €500,000 tax-value threshold, you are in the worst position: no exemption for Italian IRES taxpayers, and treaty-rate withholding for non-EU parents. Consider whether consolidating holdings — including indirect participations through controlled intermediaries — lifts you above either threshold.

Second, if you are a UK, US, Canadian or Australian parent that has paid withholding tax at treaty rate (typically 5–15%) in any of the last 48 months, you may have a live refund claim based on the 1.2% Article 63 TFEU argument. The 48-month statute of limitations runs from the date the withholding tax was levied. Do not let that window close without an assessment.

Third, assess whether the DL 38/2026 corrective decree changes your position retroactively. For participations between 5% and 10%, the interplay between the Budget Law and the subsequent decree requires bespoke analysis of each distribution resolution date.

Fourth, document beneficial ownership and substance carefully. The substance-based approach of the 2026 reform is aimed at preventing the artificial fragmentation of shareholdings through intermediary entities, and the same anti-avoidance logic will be applied by the Italian Tax Authority when reviewing refund claims and restructuring transactions alike.

The Italian Tax Authority's position remains hostile to non-EU claimants, and the divergence between the courts and the administration means that most refunds will require formal litigation. What the 2026 case law sequence — from Pescara's first-instance decision No. 509/2024 through the Abruzzo appeal No. 93/2026 to the Italian Court of Cassation's ruling No. 4761 of 3 March 2026 — has established is that the legal foundation for those claims is now solid. The administrative resistance, however vigorous, is no longer supported by any plausible reading of Article 63 TFEU.

For a UK or US parent company, the current Italian dividend regime is therefore simultaneously a compliance burden and a legal opportunity: a structural overcharge that Italian courts have said must be repaid. The decision is when, and how, to claim it.
