France rewards its residents for backing young innovative companies through the IR-PME framework — the successor to the historic Madelin reduction — with rates that now depend on how innovative the target company is.
The current structure, confirmed against official French sources: the standard IR-PME reduction is 18% (25% for accredited social-utility enterprises, ESUS). For young innovative companies the rates rise sharply: 30% for a JEI (jeune entreprise innovante), 50% for a JEIR (the R&D-intensive ‘rupture’ category), and 40% for the JEII impact category — which was brought into the scheme from 21 February 2026. Investment caps are €50,000 per year for a single taxpayer and €100,000 for a couple taxed jointly; the JEI-family subscription window runs to 31 December 2028, with total JEI-family relief capped at €50,000 per household over the 2024–2028 period.
Two structural rules shape every decision. First, a five-year holding commitment: sell early, or let the company lose its status, and the tax authority claws the relief back. Second, an either/or with the PEA: shares claiming these reductions cannot sit inside a PEA or PEA-PME wrapper, so French investors choose between upfront relief and long-term tax-free compounding. Note also a distinction our verification confirmed: the standard 18% IR-PME reduction counts toward France’s global €10,000 annual cap on tax advantages, but the JEI, JEIR and JEII reliefs sit outside that cap, governed instead by their own €50,000 cumulative ceiling.
The boundaries: French tax residency is an absolute requirement, and eligible targets are unlisted French and European small and mid-sized companies — a UK venture does not qualify. For a French resident looking at UK early-stage opportunities, the honest position is that no French relief follows the money: the decision rests on the venture itself — its team, governance and structure.
