This study examined the effect of audit quality and financial reporting quality of deposit money
banks in Nigeria. The objectives of the study were to examine the effect of audit fees and audit
tenure on earnings quality of deposit money banks in Nigeria. Secondary data which were sourced
from the annual report of the selected deposit money banks from 2014-2023 were used for the
study. The population is the 21 listed deposit money banks and purposive sampling technique was
adopted to select 10 banks as the sample size. We employed the ex-post facto research design and
multiple regression analysis. Data collected was analyzed using EViews 13 in the following order:
descriptive statistics, correlation analysis, panel unit root test, estimation of the regression models
and then performance of some diagnostics tests. The findings revealed that audit tenure has a
negative significant effect of -0.554212 at 1% significance level on earnings quality, audit fees
have a positive significant effect of 1.06E-05 at 1% level of significance on earnings quality. The
study recommended that management should continue to maintain the present audit fees for as
much as the signs are aligned with expectations and management should maintain effective audit
firm rotation, increase audit scrutiny, ensure cooling periods in order to mitigate the negative
effect of audit tenure on earnings quality.
