30% compulsory levies cannot finance 57.3% public spending

Total public revenue was 52.2% of GDP in 2025 while compulsory levies were 43.6%, a mechanical difference of 8.6 GDP points. If that other revenue share stayed unchanged and compulsory levies fell to 30%, total revenue would be about 38.6% of GDP.

Mechanical revenue with 30% levies38.6% GDP
Static spending gap at 2025 GDP€559.3bn

This is not a final accounting target. But it establishes the consistency constraint: a France with durable 30% compulsory levies must also have public spending representing a much smaller share of national output.
