Flat Tax Hike Under Discussion In French Government

The prospect of an increase in the flat tax resurfaces in budget discussions. Ahead of the 2026 finance bill, Bercy would consider raising the single flat tax, set since 2018 at 30 %. No decision has been made yet, but the return of this measure, long considered a fiscal marker of Macronism, is already causing tensions. In a context of structural deficit and revenue pressures, the stability of the savings tax framework could be called into question.

A budgetary measure considered for 2026

While the situation becomes very worrying for France , the idea of raising the PFU from 30 % to 33 %, or even up to 36 %, is among scenarios discussed in preparing the 2026 budget. At this stage, it is only a hypothesis studied by the government.

This is a prospect that comes back on the table, even if nothing has been decided. The objective is to mobilize new revenues to contain the public deficit, expected to be 4.7 % of GDP in 2026. Indeed, each percentage point increase of the flat tax would bring about 240 million euros, which would raise potential gains to more than 1.4 billion euros if the rate reached 36 %.

This scenario, although undecided, already fuels speculation. Since its establishment in 2018, the PFU at 30 % embodies an economic approach favorable to investment and tax simplicity. Its possible reconsideration thus represents a strategic turning point.

However, opinions differ. Some members of the majority fear “breaking a strong symbol of Macron’s term”, while others argue for a revision to meet budgetary imperatives. Several technical arguments support this reopening of the file :

• An increase of 3 points (from 30 % to 33 %) would generate about 720 million euros more ;

• A rise to 36 % would bring nearly 1.44 billion euros per year, according to internal estimates ;

• The flat tax remains lower than the tax burden on savings income in other European countries, which fuels debate on its social legitimacy ;

• Some in the majority believe that large capital holders can contribute more without harming the overall economic climate.

Increasing pressure around high net worth individuals and tax loopholes

Beyond the flat tax, it is the entire capital taxation that could be reconsidered in the coming months. The budget debate for 2026 fits into a broader dynamic, where other levers are also mentioned.

Among them, the highly publicized “Zucman tax”, a 2 % contribution on wealth exceeding 100 million euros, reappears as an alternative or complement to raising the PFU. Although this tax was rejected by the Senate after adoption by the Assembly, it remains politically active. In parallel, reflections are underway on tightening certain tax loopholes and possibly reducing exemptions overseas, within the framework of the LODEOM scheme.

The equation is delicate. The government intends to avoid a fiscal shock already denounced by several business representatives, notably the AFEP, which warns about the effects of such a shift on competitiveness, investment, and employment.

Prime Minister Sébastien Lecornu has, for his part, closed the door on a return of the wealth tax (ISF), while maintaining a trajectory of budget consolidation. In this context, raising the PFU could be seen as an intermediate compromise, politically less explosive but not without economic consequences.

For savers, an increase in the flat tax would directly affect the net yield of many investments, including those made in cryptos when they are not held in tax-advantaged accounts. This could also revive shifts toward the progressive scale, or even accelerate certain tax optimization strategies.
