This study investigates the effect of corporate tax planning on the profitability of quoted firms in the Growth Board of theNigerian Exchange Group. The study adopts a panel data research design, covering eight (8) quoted firms over a ten-year period from2015 to 2024. Secondary data were obtained from the annual reports and accounts of the selected firms, focusing on income effectivetax planning (IET), debt tax planning (DTS), and non-debt tax planning (NDT) as measures of corporate tax planning, while return oninvestment (ROI) was used as the indicator of financial performance. The study employs panel regression analysis, including pooledOrdinary Least Squares (Pooled OLS), Fixed Effects (FE), and Random Effects (RE) models, with the Hausman test used to determinethe most appropriate model. Results from the Fixed Effects model reveal that income tax planning (IET), debt tax planning (DTS), andnon-debt tax planning (NDT) all have a positive and statistically significant effect on ROI at 5% significance level. The Hausman testconfirms the Fixed Effects model as the most suitable for interpretation. The findings indicate that strategic tax planning enhances firmprofitability, highlighting the importance of efficient tax management in value creation for shareholders. The study concludes thatcorporate managers should implement systematic tax planning strategies to maximize financial performance while ensuringcompliance with regulatory frameworks.
