The purpose of this study is to examine the relationship between financial leverage and financial performance of Savings and Credit Cooperative Societies in Tanzania (SACCOS). The study used a panel data set of 115 SACCOS in Tanzania in the period 2011–14 and fixed-effects models for analysis. The study considered the direct relationship between financial leverage and financial performance and the moderating effect of board meetings on the relationship between financial leverage and the SACCOS’s financial performance. The results show that financial leverage is negatively and significantly related to SACCOS financial performance. Also, board meetings have the significant and positive moderating effect on the financial leverage–financial performance relationship. Finally, the study suggests that SACCOS in Tanzania need to embrace more on mobilising internal funds from their members instead of relying on debt. This can reduce the dependence on debt which has been one of the operational costs’ drivers of the SACCOS in Tanzania.
