Small and medium-sized enterprises (SMEs) are one of the buoyant businesses in the global economy with abundant resources that have not been fully exploited. Despite several revelations on the challenges of SMEs, little to none have comprehensively captured financial factors affecting the performance of SMEs, particularly, in the Kenyan leather sector. This study explores financial factors that are affecting the performance of SMEs using the case of the leather industry sector in Kenya. The study data was collected by administering questionnaires to 300 respondents who were randomly chosen from SMEs within Kenyan leather sector. The study found that financial literacy, credit access and tax are statistically significant financial factors affecting the performances of SMEs. As a result, the study recommends that Government should increase its commitment to develop SMEs by offering favorable tax rates and tax exemptions to SMEs especially those in the leather sector of Kenya. Also, SMEs should heighten their financial literacy which will help augment their access to credit.
