The study examined the effect of corporate tax on the sustainable financial
performance of listed firms in Nigeria, specifically the listed manufacturing firms.
The study employed an ex post facto research design using data from 10 listed manufacturing firms. The data span across 5 years ranging from 2013-2017 and were analyzed using simple linear regression. Findings from the study revealed that
corporate tax payment has no significant effect on the return on equity of firms.
Further findings revealed a positive and significant effect of corporate tax payment on the debt to equity ratio of the listed firms. Hence, based on the results obtained from this study it is recommended that Investors in the manufacturing sector should use their tax pay-out policy as a tool for financing decisions as it greatly affects the firm's debt to equity ratio (Capital combination) decision making. Also, they should encourage the prompt payment of tax as it has no significant effect on their returns but in turn, increases the market value of the firms.
