The Left party in the German Bundestag is criticizing the federal government's promotion of occupational pensions, arguing it leads to billions in lost revenue for the statutory pension, nursing care, and health insurance systems. Sarah Vollath, the Left's spokesperson for pension policy, revealed in a parliamentary inquiry that the tax and social security-free nature of salary conversion for occupational pensions results in significant contribution shortfalls. While exact figures are difficult to ascertain, estimates suggest these losses have grown from approximately two billion euros in 2007 to around three billion euros annually by 2023, with roughly half impacting the statutory pension insurance. Vollath contends that this policy weakens the solidarity-based statutory system and that recent legislation, like the Betriebsrentenstärkungsgesetz II, exacerbates this financial gap, potentially leaving employees with less overall retirement income.
