Data reported by the Financial Times shows that wage taxes across OECD countries reached their highest level in nearly a decade, averaging 35.1% for a single worker in 2025.
Taxes increased in 24 out of 38 member countries, reflecting growing fiscal pressures as governments seek to boost public revenues.
The United Kingdom recorded the largest annual increase, signaling tighter fiscal policies aimed at addressing economic challenges and rising debt levels.
Analysts warn that higher wage taxes could weigh on household purchasing power and consumption, particularly amid rising living costs.
The trend highlights the ongoing challenge for policymakers to balance revenue generation with economic growth while avoiding excessive burdens on workers.
