Tax consolidation agreement: templates and pitfalls to avoid

Quick answer. The tax consolidation agreement organises how corporate tax (IS) is shared within a French consolidated group. It is not mandatory but strongly advised: the law (FTC art. 223 A) leaves wide latitude, provided no subsidiary bears a heavier charge than it would outside the group, on pain of an abnormal management act.

You have elected French tax consolidation, or you are considering it. The tax mechanics are familiar: a parent company becomes the sole taxpayer for the group's corporate income tax. One question, however, is rarely settled in time, yet proves decisive in an audit or a shareholder dispute: how should that tax charge be shared among the group companies? This is exactly what the tax consolidation agreement governs. Poorly drafted, it weakens the structure. Well built, it secures each entity's cash position and the rights of minority shareholders.

In a consolidated group, the parent becomes the sole taxpayer for the corporate tax due on the aggregate result (FTC art. 223 A). Subsidiaries held at least 95 % no longer pay their tax directly: the parent captures the savings (offset losses, neutralisations) and settles the overall tax. The tax consolidation agreement is the internal contract that allocates this charge, and the fate of the savings, among member companies.

A frequently overlooked fact: this agreement is not a legal obligation. No text requires it, and it does not have to be filed spontaneously with the tax authorities. But its absence is a major risk. Without it, the parent captures a loss-making subsidiary's tax saving with no formalised consideration, which may be read as an indirect subsidy or as harming minority shareholders. For the overall framework of the regime, you can revisit our article on how the French tax consolidation regime works, which sets the basics before moving to drafting.

The tax administration's guidance (BOI-IS-GPE-30-30-10) confirms that member companies are free to set, by agreement, how the tax charge, or the tax saving from the regime, is shared. This freedom is not absolute: it stops where the allocation makes a subsidiary bear a heavier charge than it would have borne had it not belonged to the group.

Three main methods coexist in practice. The choice depends on the presence of minority shareholders, the subsidiaries' profitability and the group's cash policy.

Here is the sequence we run in our group-structuring files:

1. Choose the corporate tax allocation method. Pick a method that never makes a subsidiary bear a heavier charge than it would outside the group.
2. Define how tax savings are shared. State who keeps the saving arising from offsetting a subsidiary's losses or financial expenses.
3. Frame the treatment of departing subsidiaries. Provide a compensation clause up to the loss actually suffered.
4. Provide for financial neutrality. Organise internal cash flows so the agreement is genuinely applied.
5. Have the agreement approved. Validate it through the competent bodies and, with minority shareholders, secure the regulated-agreements procedure.
6. Archive and update every year. Keep the agreement available to the authorities and revise it on each entry or exit from the scope.

The group regime option runs for five financial years and renews by tacit agreement (FTC art. 223 A). The agreement itself is best reviewed on every change of scope.

The line between a valid agreement and a reclassifiable one rests on three principles set out by the guidance and the case law of the Conseil d'Etat.

• The allocation must not make a subsidiary bear a heavier tax charge than it would have outside the group: that would be an abnormal management act (BOI-IS-GPE-30-30-10).
• The allocation must not harm the corporate interest of each group company.
• The allocation must not impair the rights of minority shareholders of the consolidated subsidiaries.

As long as these conditions hold, the parent bearing the group's tax is not read as an indirect subsidy. Conversely, an agreement that systematically impoverishes a subsidiary for the parent's benefit, with no consideration, exposes the group to a reassessment and to a challenge from minorities. This is also a point the authorities may examine during a tax audit, alongside other intra-group flows.

Departing subsidiary. When a subsidiary leaves the group, its losses may have been permanently attributed at group level. The agreement can provide an exit indemnity. As long as it does not exceed the loss actually suffered by the subsidiary from the attribution of its losses to the group, it is not a taxable subsidy for that subsidiary. Beyond that, the excess becomes a taxable subsidy. Calibrating this clause is one of the most technical points of the agreement.

Minority shareholders. If a consolidated subsidiary has shareholders outside the group, pure neutrality can harm them: they would finance a tax saving that flows up to the parent with no return. Reallocating the saving to the relevant subsidiary is then more prudent. The agreement also usually falls under the regulated-agreements procedure of the Commercial Code.

Group with a holding and cross-flows. When the parent also invoices services to the subsidiaries, the consolidation agreement must dovetail with the policy on intra-group management fees: two distinct flows, two justification logics, one consistency check. For ownership structures, our holding versus SCI comparison clarifies the choice of vehicle upstream.

The underestimated risk is not the tax rate, it is internal consistency. An agreement signed but never applied is almost as bad as none: if cash flows do not follow the written allocation key, the document loses its evidential force. We also see agreements frozen since inception, never updated after a new subsidiary joined, creating a grey area over the fate of its tax savings.

Another point: do not confuse the group's IS charge with the owner's personal tax. The standard IS rate is 25 %, with a reduced rate of 15 % up to 42,500 euros of profit under conditions (FTC art. 219). On distributions, dividends paid to individuals fall under a single flat tax of 31.4 % since the CSG increase. The consolidation agreement only governs how tax is shared between companies: it changes neither the IS rate nor the shareholders' personal taxation.

Recently, the director of a services group with three consolidated companies, including a subsidiary with a 12 % minority holder, approached us after that shareholder left. The original agreement provided pure neutrality: all savings flowed up to the parent. The minority holder rightly objected to having funded, for three years, a tax saving his subsidiary had never seen. We rewrote the allocation key to reallocate the loss-related saving to the relevant subsidiary, then recalculated the flows for the financial years still open to adjustment.

Our reading is this: the consolidation agreement is not a legal formality, it is a financial governance tool. It must be designed before the election, not drafted hastily at the first audit. The key trade-off lies between the simplicity of neutrality, ideal in a wholly owned group, and the protection of minorities, which calls for finer reallocation as soon as an outside shareholder enters a subsidiary's capital. As chartered accountants registered with the Ordre and statutory auditors, we treat the agreement as a living document, to be reviewed on each change of scope and dovetailed with the management-fee and distribution policy. For groups under construction, our holding tax support secures the whole structure.

Hayot Expertise tip. Date and sign the agreement before the first consolidated year opens, include a quantifiable exit clause, and schedule an annual review in the closing calendar. Keep the document with the flow evidence: that traceability, more than clause sophistication, is what withstands an audit.
