Internal Control Systems and the Revenue Collection Performance among Local Government Authorities (LGA) in Tanzania

Abstract

Local government authorities (LGAs) face significant challenges in revenue collection due to inadequate internal controls, leading to inefficiencies, fraud, and inconsistent reporting. This study investigates the effect of internal control systems on revenue collection performance within selected LGAs in Tanzania, namely Mbeya, Mwanza, and Manyara. Using a cross-sectional survey design, data were collected from 400 respondents across the three councils. Two Stage Least Square regressions were employed with the frequency of external audits as the instrument to control for endogeneity. The findings indicate that while certain internal control measures, such as financial record accuracy and internal audits, positively influence revenue effectiveness and reliability, challenges such as fraud and delayed reporting adversely affect revenue growth and operational efficiency. LGAs should enhance internal audit functions, improve financial record accuracy, strengthen fraud prevention, optimize reporting timelines, and enhance monitoring mechanisms through investment in technology and staff training. Policymakers should develop a standardized framework for internal controls, invest in technology infrastructure, encourage Public-Private Partnerships (PPP), and regularly review policies to ensure effective revenue collection in LGAs.
