This paper investigates the determinants of dividend policy in Tanzania. The study employed a panel data of non-financial firms listed on the Dar es Salaam Stock Exchange (DSE) for the period 2008–2017. The paper reports profitability, liquidity, firm size, leverage, firm growth, previous dividend, and GDP as the major determinants of corporate dividend policy. According to the results, leverage, firm growth, and GDP are negatively related to dividend payout ratio while firm size, profitability, liquidity, and lagged dividend are positively related to dividend policy. More specifically, large-sized firms, highly profitable firms, and firms who paid dividend in previous years are more likely to consider paying dividend. However, payment of dividend will all depend on whether the firm is liquid enough to afford that. On the other hand, high-growth and leveraged firms would not probably consider paying dividend, and will, therefore, opt saving money to finance their expansion and honor their debt obligations. Following these results, corporate managers are advised to consider preferences of investors towards developing corporate dividend policy; to strive paying dividend whenever economically viable (as it signals the firm’s reputation), and to limit excessive borrowing to protect firms from getting into financial meltdown (although borrowing is considered a control tool for agency-related problems).
