Financial retirement planning is essential and critical for every worker especially for the self-employed workers to face their retirement. The purpose of this paper is to identify factors relating to self-employed individuals' financial retirement planning for their future retirement, and shed light on future research directions for future researchers. This paper revisits existing literatures on retirement policies in Malaysia and some countries in the world, and also on financial retirement planning. Financial retirement planning literatures suffers a gapping problem in term of the scarcity of literatures on self-employed workers' planning for their retirement. Many researches in the past put more focus on retirement planning behavior of salaried workers. By conducting a conceptual study on this gap, hopefully it will offer policy makers and practitioners new insights to search for new constraints, objectives, and sources of information regarding retirement issues involving self-employed individuals in this country. This paper provides backgrounds and insights on self-employed workers' retirement preparation for future researchers to study. As a conceptual study, this work derived from secondary sources. Hopefully, this study provides researchers and practitioners some understanding of each factor proposed towards understanding financial retirement planning among the self-employed workers.
