The purpose of this study is to present policy implications for the public by empirically analyzing the intention of additional tax burden to expand disaster policy. The willingness to pay additional taxes is an important empirical analysis topic in social science, but interest in disaster management and disaster policy was insufficient. For empirical analysis, influencing factors were analyzed by dividing them into disaster experiences at the individual level, disaster management at the organizational level, and disaster awareness at the social level. As a result of the analysis, in order for the people to agree to expand disaster policy and to be willing to pay additional taxes, the government and disaster organizations must turn into trusted organizations. In addition, it is important to present a responsible appearance, and public relations strategies that raise public awareness of the dangers of disasters need to be discussed as important.
