Findings in the original version: EY describes a \\draft\\ Finance Bill and proposed surcharge changes. The surcharge percentages are not necessarily the combined CIT effective rate; threshold/base/period details matter.
France is extending its exceptional corporate income tax surcharge into a third year. The 2027 Finance Bill, submitted to Parliament on October 1 and now under National Assembly floor debate as of October 13, proposes to keep the surcharge in place through financial year 2027. If you have French entities above €1.5 billion in consolidated worldwide revenue, this lands directly in your Q4 provision model — and you need to be ready to accrue the moment it is enacted.
What the Bill Proposes
The exceptional contribution is not new. France introduced it for financial year 2025, extended it for 2026, and now proposes a third year covering financial years ending on or after December 31, 2025. For calendar-year companies, that means FY2027 is the in-scope period.
The threshold has not changed: €1.5 billion in consolidated worldwide revenue, tested against either the current or prior financial year. What has changed is the rate structure. The 2027 bill proposes to reduce rates meaningfully relative to year two. For groups at or above €3 billion in revenue, the proposed rate is 31.4% — down from 41.2% in year two. For groups in the €1.5 billion to €3 billion range, the rate is also reduced from the prior year's 20.6%, with a lower rate replacing it. The standard French corporate income tax rate of 25% does not change.
The exceptional contribution is computed on French CIT before credits, not as a standalone levy. It is not deductible for French CIT purposes. That last point matters for how you measure the effective French tax burden — the contribution is a gross-of-credits surcharge, which means the combined charge can be material even for companies with significant French R&D credits.
EY published its alert on this on October 8, the day after the bill reached the National Assembly. KPMG published its analysis on October 1. Parliament has no majority; the timeline is uncertain.
The ASC 740 Enacted Date Is the Only Threshold That Matters
For ASC 740 purposes, a tax rate change produces current and deferred tax consequences only when enacted under the law of the relevant jurisdiction. In France, enactment means passage by both chambers of Parliament and signature by the President. A draft submitted on October 1 and currently in floor debate is not enacted.
This has a direct, mechanical consequence: you do not accrue the year-three surcharge today. But you must be ready to accrue the moment enacted status is confirmed — and EY's October 8 alert projects a final parliamentary vote by the end of December. If enacted before December 31, the surcharge hits your Q4 provision. If enacted in Q1 2027, it is a Q1 event. For companies with material French operations, the difference in FY2026 ETR between these two scenarios is not rounding.
The situation is further complicated by the fact that the French government has no reliable parliamentary majority. KPMG noted in its October 1 analysis that the absence of a majority in the National Assembly makes the schedule hard to keep. The government retains the ability to use the constitutional "49.3 procedure" — forcing adoption without a vote — but that creates political risk. If a motion of censure is filed and succeeds, the government falls and the bill dies. This is not a theoretical scenario.
Senate amendment is also live. Even if the National Assembly passes the bill, the Senate could amend rates or thresholds. The final enacted text may not match the October 1 draft. Build your provision model on the proposed rates as a reasonable estimate, but flag that the enacted text controls.
The Silence-Implies-Consent Mechanism: A Provision Nuance
The 2027 Finance Bill contains a second item that tax departments with French entities should flag: an experimental mechanism that makes silence imply consent for certain tax ruling requests. Under the proposal, qualifying companies can submit an interpretation of a tax provision to the French tax authority. If the authority does not respond within three months, the company treats its interpretation as accepted.
This changes how tax certainty works in France. Currently, a ruling request sits in queue with no response deadline. Under the proposed mechanism, three months of silence creates constructive acceptance. Whether the implementing regulations define "qualifying companies" and "qualifying interpretation requests" broadly or narrowly will determine how useful this is. Expect narrow initial scope.
For ASC 740 uncertain tax positions in France, this mechanism is material. Under ASC 740-10, the recognition of an uncertain tax benefit requires a "more likely than not" threshold. If a company submits a ruling request under the new mechanism and receives constructive acceptance through silence, that changes the recognition and measurement analysis. Document the mechanism in your UTP workpapers and flag it with your auditors. Do not assume the old analysis still controls once the mechanism is enacted.
What Your French Provision Needs Right Now
Three concrete actions before you close Q4:
Identify your tier. Pull your French consolidated entities and map them against the €1.5 billion and €3 billion revenue thresholds. The surcharge applies at the group level, not the entity level — but the French tax computation is entity-specific. For groups above €3 billion, model the 31.4% proposed rate on French CIT before credits. For groups in the €1.5 to €3 billion band, model the reduced proposed rate.
Build a two-scenario model. Scenario A: enacted before December 31, 2026. The surcharge is accrued in Q4, the FY2026 ETR increases. Scenario B: enacted in Q1 2027. No FY2026 impact. Your CFO needs to see both scenarios and the ETR sensitivity between them before the year-end close. If the difference is material, it belongs in your earnings guidance framework. This is not a post-close surprise you want to discover in February.
Build a monitoring cadence. Assign a watch owner on the parliamentary timeline. The National Assembly vote (or 49.3 invocation) is the enacted-date trigger. After that, Senate passage and presidential signature. Starting November 1, that owner should check status weekly. In Clarity Tax's knowledge graph, we track enacted-status events at the country level in real time — this is exactly the kind of jurisdiction-specific trigger that your provision workflow should consume automatically rather than via a calendar reminder.
What to Do Monday Morning
1. Pull every French consolidated entity above €1.5 billion in revenue. Identify the applicable tier — €1.5B to €3B or above €3B — under the proposed rate structure. 2. Calculate the French CIT before credits for the relevant period. This is the base on which the surcharge applies — not gross revenue, not net income. 3. Build a two-scenario provision model with the ETR impact of enacted-before vs. enacted-after December 31. Quantify the FY2026 ETR gap and put it in your management briefing. 4. Assign a monitoring owner for the parliamentary enacted-date trigger. Minimum weekly check after November 1, with escalation protocol if the 49.3 procedure is invoked. 5. Flag the silence-implies-consent mechanism with your UTP team. Identify any open French ruling requests that could fall under the new mechanism once enacted. Update your ASC 740 recognition analysis accordingly.
