This study examined the impact of financial control mechanisms on local government accounting, transparency, and accountability within five selected local government areas (LGAs) in North-Central Nigeria. Using a descriptive survey design, primary data were obtained from 125 respondents comprising treasury, audit, and planning officials. Data were analysed using descriptive statistics and regression analysis to test three hypotheses on the relationship between financial control mechanisms and accountability outcomes. The findings revealed that although statutory control structures such as budgeting, internal audit, and external oversight exist in Nigerian local government areas, their effectiveness is constrained by weak enforcement, manpower shortages, and limited transparency. Weak financial control significantly undermines service delivery and citizen trust. The study recommended automation of revenue processes, capacity building, and stronger audit enforcement as sustainable reforms for transparent local governance.
