Overview

• Prime Minister Sébastien Lecornu’s entourage says no decision has been taken and consultations are ongoing as the 2026 budget is prepared.
• The so‑called Zucman tax would set a 2% minimum on fortunes above €100 million, with Gabriel Zucman projecting up to €20 billion in revenue and many economists estimating closer to €5 billion.
• Centrist leader Marc Fesneau backs a return to an ISF‑type approach targeting “improductive” wealth and excluding business assets, a path seen by some in the majority as less disruptive than the Zucman plan.
• Marine Le Pen rejects the Zucman tax as “stupid and harmful,” arguing it would drive departures and proposing a shift from the property‑based IFI to a financial‑wealth levy with exemptions for primary homes, professional assets and most small‑business stakes.
• Policymakers are also eyeing stronger anti‑avoidance tools against holdings used to shield assets, with Senate president Gérard Larcher urging a companion “justice fiscale et sociale” bill, as polling shows broad public support for taxing the very rich.
