The income security system has had various social safety net systems since the 2000s. However, due to the limitations of each system, there are still wide no-care zone for the working poor. Therefore, evaluating the no-care zone and policies of the income security system for the working poor and identifying the consistency between the systems is an important issue. The following is what this study is trying to say. The Emergency Welfare Support System needs to be dramatically reformed in order for the working poor, who are in the no-care zone, to maintain a stable livelihood. In the short term, through the connection between the Emergency Welfare Support System and the National Employment Support System, livelihood support is provided, employment education, training, and job placement to households in crisis. In the long term, the earned income tax credit(EITC) system must also be integrated and operated along with the system.
