This paper discusses redesigning Basic Livelihood Security System(BLSS) in South Korea from an inclusive citizenship perspective. Considering citizenship has the dual nature of inclusion and exclusion, this topic was explored with the aim of mitigating its exclusionary nature and seeking a comprehensive welfare state. Especially considering the rise of the employment-centered reciprocity discourse that links citizenship eligibility to paid work conditions, in this paper, alternative approaches were examined by explored the redesign of BLSS from an inclusive citizenship perspective. Through the above review, it has appealed for the need to improved welfare accessibility and increase in benefits for guaranteeing social integration of disadvantaged as citizenship rights. In the dimension of social obligations, it proposes to move beyond the narrow view that only sees paid work as a social contribution from a productivist perspective, and to expand to include unpaid work essential for social reproduction such as care and volunteer activities. The arguments could contribute to political discussions and academic research that imagines ‘comprehensive welfare’and seeks to implement it in the real world.
