Abstract:
Custom reforms are crucial for the economic health of any nation. In Kenya, despite an
increase in tax revenues from Ksh 2.166 trillion in the 2022/2023 fiscal year to Ksh 2.407
trillion in 2023/2024 an increase of Ksh 240.565 billion, which includes Ksh 791.368
billion from customs taxes reflecting a growth of 4.9% the government continues to face
deficit financing. This has necessitated reliance on foreign loans to bridge the revenue
shortfall, raising significant tax concerns for future generations. To mitigate government
debt, there is a pressing need to enhance current tax revenue. This study investigated the
moderating effect of institutional capacity on the relationship between customs reforms
and customs revenue collection at the Kenya Revenue Authority (KRA). The independent
variables included customs automation reforms, audit-based controls, and enforcement
reforms, while revenue collection served as the dependent variable, with institutional
capacity acting as a moderator. The research was guided by theories such as commodity
tax reforms, the unified theory of acceptance and use of technology, and public
expenditure theory. Primary data was collected through a structured questionnaire
featuring closed-ended questions. The target population consisted of 1,823 management
and technical staff, from which a sample of 328 respondents was selected using a
stratified random sampling technique. Data analysis was performed using the Statistical
Package for the Social Sciences (SPSS), employing descriptive statistics (means and
standard deviations) and inferential statistics (correlation and multiple regression
analysis) to explore the relationships between variables. The findings from the multiple
regression analysis indicated that customs automation reforms significantly and positively
influenced customs revenue collection ( β 1 =0.187, p=0.000<0.05). Similarly, audit-based
controls ( β 2 =0.208, p=0.000<0.05) and enforcement reforms ( β 3 =0.111, p=0.016<0.05)
also had significant positive impacts on revenue collection. Additionally, institutional
capacity was found to negatively and significantly moderate the relationship between
customs automation reforms, audit-based controls, enforcement reforms, and customs
revenue collection at the Busia and Malaba border posts ( β 4 =0.176, p=0.000<0.05).
However, it positively moderated the relationship between customs automation reforms
( β 5 =0.067, p=0.007<0.05) and audit-based controls ( β 6 =0.054, p=0.026<0.05) with
customs revenue collection. Furthermore, it also significantly influenced the relationship
between enforcement reforms and customs revenue collection ( β 7 =0.456, p=0.000<0.05).
The study recommends that the KRA fully implement customs reforms to strengthen
customs automation, audit-based controls, and enforcement measures for enhanced
revenue collection. It concludes that customs reforms have a significant positive effect on
customs revenue collection at the Busia and Malaba border posts. To optimize these
reforms, the KRA should harmonize their efforts, prioritize infrastructure development,
and focus on implementing Information Communication Technology and automated
systems.
