Germany faces tax hikes and reforms as public spending soars beyond 50% of GDP

Clemens Fuest, president of the Ifo Institute, has warned that rising government spending will force higher taxes and deeper reforms. With public expenditure set to exceed 50% of economic output by 2027, he argues that urgent action is needed to avoid long-term financial strain. His proposals include stricter spending limits and major changes to healthcare and pensions. Fuest highlights that much of the recent increase in government spending has been funded by debt. This approach, he argues, only delays necessary debates rather than solving them. Instead, he calls for a clear framework to address financial challenges without relying on further borrowing.

One of his key recommendations is a medium-term cap on public spending, limiting it to 49% of economic output. Without such controls, he warns, the growing share of expenditure will lead to higher taxes and levies over time. Fuest also stresses the need for fundamental reforms in state-run systems. Healthcare and pensions, he argues, must shift toward a basic provision model, supplemented by private savings. Chancellor Friedrich Merz (CDU) has similarly suggested that statutory pensions will only cover basic needs in retirement. The economist insists that politics and society must tackle these issues now. Postponing decisions through more borrowing, he says, will only worsen the risks of an unsustainable spending ratio.

Fuest’s warnings come as rising defence spending adds further pressure to public finances. His proposed reforms aim to stabilise government expenditure and prevent future tax hikes. Without action, he cautions, the financial burden on taxpayers and the economy will continue to grow.
