This study investigates the factors influencing voluntary tax compliance among small and
medium-sized enterprises (SMEs) in Bayelsa State, Nigeria. Utilizing a quantitative research
design, the study surveyed a population of 130 SMEs, employing a stratified random sampling
technique to ensure representative data collection. The research explores the relationships
between financial literacy, perceptions of the fairness of the tax system, trust in government
institutions, and the informal status of businesses. The findings reveal a strong positive
correlation between financial literacy and tax compliance, indicating that SMEs with higher
financial knowledge are more likely to meet their tax obligations. Additionally, perceptions of
the tax system as fair significantly influence compliance behaviour, with businesses more
inclined to comply when they view the system as equitable. Trust in government institutions
emerged as a crucial determinant, suggesting that increased credibility and transparency in
tax administration can foster greater compliance among SMEs. Conversely, the informal status
of businesses showed a weak correlation with compliance. The study concludes that enhancing
financial literacy, improving perceptions of fairness in the tax system, and strengthening trust
in government institutions are vital for increasing voluntary tax compliance. Recommendations
include targeted educational programs for SMEs and policy reforms aimed at enhancing
transparency and trust in tax administration. These insights contribute to the existing literature
on tax compliance and provide a foundation for future research and policy development to
support the growth and formalization of SMEs in Bayelsa State.
