The concept of spousal splitting in Germany has come under scrutiny due to its impact on secondary earners, particularly women aged 45 to 66. The study conducted by the German Institute for Economic Research indicates that existing tax laws, along with the regulations surrounding mini-jobs and health insurance contributions, make additional work less appealing. Many secondary earners feel that the financial benefits of taking on more work do not justify the extra effort involved.

The study suggests that if the spousal splitting system were abolished, there could be a significant increase in labor participation among women in this age group. Specifically, it reveals that such a policy change could raise the employment rate by nearly 1.5 percentage points and boost the total number of working hours by about three percent. This shift in workforce dynamics could lead to the creation of around 175,000 full-time jobs, demonstrating the potential for reform in labor policies to unlock greater economic activity.

As discussions around fiscal policy and the support for secondary earners gain momentum, the findings of the study may influence future legislative decisions in Germany. The urgency for change becomes ever more apparent as the economy seeks to recover post-pandemic and aims for sustained growth, making it critical to address barriers that prevent individuals from engaging more fully in the labor market.
