Medef Warns Renewal of French Corporate Surtax in 2027 Budget Would Hit Investment and Hiring

Medef Sounds Alarm Over Plans to Keep Surtax on Big Business in 2027 Budget

French business lobby Medef is bracing for the government to extend a special surtax on large companies’ profits for a third consecutive year in the 2027 budget, a move its president says will force the country’s biggest employers to pull back on domestic investment and hiring.

Patrick Martin, who heads the organisation, told journalists on 22 June that he fears the “exceptional contribution on large companies’ profits” (CEBGE) will be renewed when the government presents its next spending plans. The warning followed a meeting with Prime Minister Sébastien Lecornu the previous week, where the issue was discussed. The tax currently applies to around 300 large groups.

Martin said companies affected by the levy “arbitrate either on the level of their investments and recruitment, or on the geographical allocation” of that spending. His comments come as the Bank of France and the national statistics institute Insee have cut their growth forecasts, projecting the French economy will expand by only 0.5% to 0.7% in 2026.

In autumn 2025, the Lecornu government had already extended the surtax into 2026 with the intention of halving its yield from €7.5 billion to €4 billion. But parliamentary budget talks led Economy Minister Roland Lescure to table a surprise amendment on 27 October that added an extra €2 billion to the expected take, pushing the 2026 levy well above the government’s initial target. Medef now sees a high risk that a similar or even heavier charge will be baked into the 2027 budget.

Why the French Government Keeps Tapping Large Companies for Revenue

Medef’s Red Line: From Temporary to Permanent Tax

Medef’s central fear is that a levy advertised as exceptional is hardening into a structural feature of French corporate taxation. When the surtax was first introduced for 2025, it was framed as a one-off contribution to help repair public finances. Renewing it twice—and now considering a third extension—signals that the government has come to rely on the income it generates from roughly 300 of the country’s largest groups. Patrick Martin’s comments make clear that business sees this as a breach of trust and a signal that temporary charges can easily become permanent.

Government’s Revenue Dilemma Amid Slowing Growth

The government faces a tight fiscal equation. With the Banque de France and Insee forecasting GDP growth of just 0.5–0.7% in 2026, tax revenues from economic activity are likely to disappoint, leaving a hole that ministers may try to fill by leaning again on large businesses. Roland Lescure’s October amendment—which added €2 billion to the 2026 surtax take—shows how quickly budget arithmetic can override earlier pledges to lighten the load. If the 2027 budget preserves the surtax at a high level, it would underline that taxing big companies has become a politically easier option than cutting spending or broadening the tax base during a period of weak growth.

What This Means for Investment in France

Martin’s warning about “geographical allocation” of investment is not an idle threat. Large multinational groups subject to the surtax constantly compare the after-tax return on capital in France with other jurisdictions. A sustained higher tax rate on profits reduces that return, making it less attractive to build factories, expand research centres or add headcount in France. At a time when the government is trying to boost industrial competitiveness and attract foreign investment, a prolonged surtax risks undercutting those efforts. While no individual company has yet announced a specific pullback, the deteriorating growth backdrop and rising tax burden together create a genuine drag on domestic capital spending.

What Affected Corporates and Investors Should Watch Now

• Track the draft 2027 budget this autumn. The government will present its budget bill around September or October. The inclusion—or exclusion—of the surtax at a specific yield will be the clearest signal for affected companies and their investors.
• Assess the earnings impact on large French groups. A surtax that takes, say, €5–8 billion from the largest 300 companies materially reduces aggregate after-tax profits. Investors should model a scenario where the levy remains at or near its 2026 level, and check guidance from exposed firms in sectors such as energy, banking and luxury goods.
• Factor in investment and location risk. Companies with significant activity in France should evaluate whether a prolonged surtax changes the calculus for new projects. In public statements and private meetings with government, they can point to the gap between France’s effective tax rate and those of neighbouring countries as a lever to argue against renewal.
• Watch for any sign of a permanent replacement tax. If the “exceptional” surtax is extended again, pressure will grow on the government to redesign it as a regular corporate levy. A formal consultation or a law-reform proposal would be the moment to engage through Medef and other business groups to shape the structure of any long-term increase in corporate taxation.
