Parent-subsidiary tax régime: how should you read it?

Updated March 2026 - The régime mère-fille (parent-subsidiary régime) is one of the most widely used tax mechanisms in the architecture of French corporate groups. It allows éligible companies, under strict conditions, to neutralise the economic double taxation of dividends flowing upward from a subsidiary to its parent company. In 2026, with the French corporate income tax (IS) rate stabilised at 25%, the stakes are significant: every euro of dividend taxed in cascade represents a direct loss for the group. Yet this régime is frequently cited in holding company projects without being genuinely understood.

The régime mère-fille is grounded in Articles 145 and 216 of the French General Tax Code (Code General des Impôts — CGI). Its objective is straightforward: prevent the same profit from being taxed twice — first at the subsidiary level where it is generated, and then at the parent company level where it is received as a dividend.

Without this régime, a profit of €100,000 earned by a subsidiary would be taxed at the 25% IS rate, resulting in €25,000 in tax. The net dividend of €75,000 would then flow up to the parent company, which would need to include it in its own taxable income. The parent-subsidiary régime breaks this tax cascade by excluding received dividends from the parent's taxable income, in exchange for a limited add-back.

The mechanism relies on two complementary articles:

• Article 145 of the CGI defines the eligibility conditions for participation securities and the required holding threshold;
• Article 216 of the CGI establishes the exemption mechanism and sets the add-back for overhead costs (quote-part de frais et charges — QPFC) to be reintegrated.

The parent-subsidiary régime is not an automatic right. It requires the cumulative fulfilment of several conditions, any one of which — if overlooked — can trigger a tax reassessment.

The parent company must be subject to French IS#

Only companies subject to corporate income tax at the standard rate can benefit from the parent-subsidiary régime. Companies subject to income tax (IR) under a tax transparency arrangement are excluded. A holding company operating under a transparency régime cannot apply the parent-subsidiary régime until it becomes subject to IS.

The 5% holding threshold#

The parent company must hold at least 5% of the share capital of the distributing subsidiary. This threshold is assessed on a full ownership basis, combining bare ownership (nue-propriété) and usufruct (usufruit). It refers to 5% of the share capital, not 5% of voting rights. This distinction matters in structures where capital and voting rights are separated.

The two-year holding commitment#

The shares must be held for a minimum period of two years from the date of acquisition. This holding commitment is a substantive condition: if the shares are sold before the two-year period expires, the parent-subsidiary régime is withdrawn and the dividends received become taxable retroactively.

Éligible securities#

The régime applies to participation securities (titres de participation) within the accounting sense — that is, shares or equity interests held with a long-term strategic purpose within the group. Also éligible are shares in companies subject to IS or an equivalent tax in an EU Member State, or in a state that has concluded an administrative assistance convention with France aimed at combating tax fraud and evasion.

The option: a formality not to be overlooked#

The parent-subsidiary régime does not apply automatically. The parent company must exercise an express option, evidenced by filing a compliant déclaration (Form No. 2059) attached to its tax return. This option is irrevocable for all éligible securities held by the company.

The exemption granted under the parent-subsidiary régime is not total. In exchange, the parent company must reintegrate into its taxable income an add-back for overhead costs equal to 5% of the gross amount of dividends received.

This add-back is a flat-rate mechanism: it is deemed to cover all the costs and expenses that the parent company incurs in managing its participation (head office costs, professional fees, legal structure costs, etc.). No additional deduction is allowed for these expenses, even if the actual costs exceed 5%.

Concrete calculation example#

A holding company holds 100% of a subsidiary that distributes €200,000 in dividends in 2026.

• Dividends received: €200,000
• Add-back for overhead costs (5%): €10,000
• Exempt amount: €190,000
• Corporate income tax on the add-back (25%): €2,500

The effective tax rate is therefore 1.25% of the gross dividend (5% × 25%), which remains far below the standard 25% rate.

This is one of the most common errors. The parent-subsidiary régime and tax consolidation (integration fiscale) are two distinct mechanisms with différent logics:

• the parent-subsidiary régime (Articles 145 and 216 of the CGI) deals solely with the taxation of dividends: it exempts dividends received by the parent company, subject to a 5% add-back;
• tax consolidation (Articles 223 A et seq. of the CGI) allows the results of all companies within a group to be consolidated: losses of one company are offset against the profits of another, and intra-group dividends are entirely eliminated (no add-back).

The two régimes can coexist. Within a tax-consolidated group, dividends circulating between group companies are eliminated by the consolidation mechanism itself. The parent-subsidiary régime remains relevant, however, for dividends received from subsidiaries not included in the consolidation perimeter — for example, foreign subsidiaries or subsidiaries held at less than 95%.

Dividends from foreign subsidiaries#

The parent-subsidiary régime applies to dividends from subsidiaries established in an EU Member State, provided that the distributing company is subject to a tax equivalent to French IS and that the tax treaty between the two states includes an administrative assistance clause. For subsidiaries located outside the EU, eligibility is much more restrictive and must be verified on a case-by-case basis.

The anti-abuse clause#

The French tax authorities have an anti-abuse clause allowing them to deny the benefit of the parent-subsidiary régime where the structure was put in place for an essentially tax-driven purpose, without genuine economic substance. This clause, derived from the EU Parent-Subsidiary Directive (Directive 2011/96/EU), targets in particular shell structures without real activity.

Breach of the holding commitment#

If the parent company sells the shares before the two-year period expires, the parent-subsidiary régime is withdrawn. Dividends received during the holding period become taxable, with applicable penalties and late-payment interest. This situation arises frequently during poorly anticipated group restructuring operations.

The accounting classification of shares#

The shares must be classified as participation securities (titres de participation) in the parent company's accounts. An erroneous classification as trading securities or fixed-asset securities may be sufficient for the tax authorities to challenge the application of the parent-subsidiary régime during a tax audit.

Hayot Expertise advice: the real risk is not simply failing to apply the régime. It is building a holding structure without verifying upfront that the dividend remittance chain, the accounting classification of shares and the tax documentation will function correctly on the day the first dividend is distributed. A structuring error discovered only later creates retroactive tax exposure that is difficult and costly to correct.

Case law has clarified several important points in recent years. The French Conseil d'État has confirmed that the 5% add-back for overhead costs cannot be adjusted based on the actual expenses incurred by the parent company, even when those expenses are manifestly higher. The flat-rate nature of the add-back is definitive.

Furthermore, the Court of Justice of the European Union (CJEU) has issued several rulings reminding Member States that they cannot treat dividends from foreign subsidiaries less favourably than domestic dividends, subject to compliance with the conditions of the Parent-Subsidiary Directive.
