In any pay-as-you-go pension system, an ageing population must be absorbed somewhere. If the ratio of pensioners to contributors rises, then contribution rates go up, pensions grow more slowly relative to wages, the retirement age rises — or the state adds more tax money, which is a fourth dial that ultimately relies on the same taxpayers.
Germany has used all of them. The statutory retirement age is rising step by step from 65 to 67 under legislation of 2007; people born in 1964 or later will reach the regular age at 67, in 2031. The sustainability factor, introduced in the 2000s, slows pension increases as the demographic ratio worsens, but has been suspended by the 48% guarantee until 2031. Contribution rates have been held at 18.6% since 2018 with the help of rising federal subsidies.
The 2025 package chose to protect the benefit level until 2031. The commission’s recommendations of June 2026 would, after 2031, use the age dial gently (linked to life expectancy) and the benefit dial again (sustainability factor), while adding a funded component. Every option distributes costs between generations differently, which is why pension reform in Germany is rarely settled for long.
Working beyond the statutory age is already possible, with supplements for each month of deferred pension. The Aktivrente adds a tax incentive to that existing option rather than changing the age itself, a distinction its supporters emphasise.
