The gathered data were analyzed using descriptive and inferential statistics. For unwavering quality, the Cronbach alpha was utilized to test the dependability of the instrument. The paper found that independence of statutory auditors had a positive significant effect on reliability of financial statements (RFS) (F= 9.018, Adj. R 2 = 0.191, p < 0.05). Also that Non-financial interest (NFI) had a positive insignificant effect on RFS, AdjR 2 = 0.195; F-Stat. = 9.255; P = 0.000. Audit tenure (AT) also had a positive significant effect on RFS, AdjR 2 = 0.078; F-Stat. = 3.877; Pvalue = 0.005. While Non-audit services (NAS) exhibited a positive significant effect on RFS, AdjR 2 = 0.118; F-Stat. = 5.568; P-value = 0.000. Based on the findings, the study recommended that audit firms should regulate the number and length of nonaudit services rendered to companies they serve as external auditor and also undergo a frequent review on financial statements where their clients have interest in order to reduce self-review and self-interest threat.Contribution/ Originality: This study contributes in the existing literature by extending the frontiers of knowledge in independent statutory audit and profitability.
