DMBs are significant players in the economy, comprising approximately 70% of market capitalization. Employing the Panel OLS regression, this study aimed to determine the impact of tax avoidance on the financial performance of deposit money banks in Nigeria. The Hausman test results suggest that for model 1 (ROA), with a p-value of 0.6961, the random effects model is appropriate, while for model 2 (ROE), with a p-value of 0.0003, the random effects model is inconsistent, indicating potential correlation between unobserved individual effects and independent variables. The Panel OLS analysis examined the relationship between tax avoidance, firm characteristics, and financial performance metrics, specifically returns on assets (ROA) and returns on equity (ROE). While tax avoidance showed no significant association with either ROA or ROE, firm age consistently exhibited a positive relationship with both metrics, indicating that older firms tend to achieve higher returns. Firm size and leverage did not demonstrate significant impacts on either ROA or ROE. In Model 1 (ROA), the R-squared and Adjusted R-squared values are 0.2001 and 0.1664, respectively, suggesting a modest fit. Model 2 (ROE) exhibits higher R-squared (0.6925) and Adjusted R-squared (0.6460) values, indicating a stronger explanatory power. Both models have Prob(F-statistic) < 0.05, implying overall statistical significance. The Durbin-Watson statistics (Model 1: 1.2810, Model 2: 1.3278) suggest minimal autocorrelation in residuals. Based on the findings, the study recommends enhancing tax monitoring, promoting stability in DMBs, improving disclosure on firm size and leverage, and ongoing monitoring of leverage levels to ensure financial stability despite tax avoidance's lack of significance on performance.enAttribution 4.0 InternationalTaxPerformanceFinancialDissertation
