Effect of Treasury Single Account (TSA) on Financial Accountability and Transparency in Nigeria’s Public Sector: Evidence from Jigawa State Ministry of Finance

Abstract

This study examines the effect of the Treasury Single Account (TSA) on financial accountability and transparency in Nigeria’s public sector, using evidence from the Jigawa State Ministry of Finance. A descriptive survey design was adopted, with primary data collected from 45 staff across Treasury, Audit, Budget, and Finance departments. Data were analysed using descriptive statistics and regression analysis. The results reveal that TSA has a significant positive effect on financial accountability and transparency (R² = 0.68, p < 0.05). Specifically, TSA improves revenue documentation, strengthens expenditure monitoring, and enhances audit trails, thereby reducing opportunities for financial mismanagement. The findings also indicate improved cash management through the consolidation of government funds, leading to better cash flow coordination and reduced idle balances. However, challenges such as inadequate staff training, weak ICT infrastructure, and resistance to digital systems persist. The study concludes that TSA is an effective public financial management tool for enhancing accountability and transparency at the sub-national level. It recommends sustained capacity building, improved ICT investment, and stricter enforcement to maximize its benefits.
