Bentele argues that the current system hinders gender equality in the labor market and complicates women’s financial independence. The proposal, initially suggested by SPD leader Lars Klingbeil, highlights the tax system as a disincentive for married women’s employment, with benefits increasing alongside income disparities. Opposition from several Union politicians, including Chancellor Merz, maintains that the spousal splitting system is essential for joint financial management in marriage. The Institute of the German Economy estimates the cost of this tax benefit to the state at approximately 25 billion euros annually.
