An Examination of the Effect of Mobile Tax Services on Tax Compliance Among SMEs in Zambia: A Case Study of Lusaka District

Tax compliance in Zambia remains a significant challenge despite increasing annual revenue collections. The country’s tax-to-GDP ratio has remained between 16.6% and 18.8% from 2001 to 2022, falling short of the 20% target set in the National Development Plan. To improve compliance and efficiency, the Zambia Revenue Authority introduced modernization initiatives such as Tax Online (2013), electronic payments (2014), and Tax on App (2020). Despite these efforts, mobile tax services remain underutilized, particularly among small and medium enterprises (SMEs), limiting their potential impact on tax compliance. This study examined the effect of mobile tax services on tax compliance among SMEs in Lusaka District, with specific focus on mobile tax services, mobile tax knowledge, and perceived benefits.

The results revealed a statistically significant relationship between mobile tax services and tax compliance (χ² = 68.222, p
