Tax Law Inefficiencies and the Reliance on PAYE in Zambia: A Comparative Legal Analysis with Lessons Drawn from South Africa

Abstract

This paper analyses the legal tax framework in Zambia and how it affects the reliance on PAYE as a revenue generator. Over the years, PAYE has continued as the best performing tax type and received little to no tax band adjustments, regardless of the change in the economic position of the country. As a result of the consistent good performance despite the existence of multiple tax bases, revenue collection has increasingly become reliant on Pay As You Earn (PAYE). This raises questions regarding the effectiveness, equity and efficiency of Zambia’s tax legal framework. Using a doctrinal approach, incorporating evidence from existing literature, including statutes such as the Income Tax Act of the Laws of Zambia CAP 323, the Value Added Tax Act of the Laws of Zambia CAP 331, the Customs and Excise Duty Act of the Laws of Zambia CAP 322, subsidiary legislation, international tax instruments and relevant case law, this study examines the extent to which legal inefficiencies within Zambia’s tax framework contribute to narrowing the tax base and the consequent overreliance on PAYE. This doctrinal methodology is complimented by a comparative analysis with South Africa’s tax framework. The study finds that, although Zambia has a comprehensive tax framework in place, the extensive tax exemptions, investment incentives, zero-rating provisions, customs duty concessions, VAT deferment schemes, legislative volatility in mining taxation, and weaknesses in the implementation of international tax standards have collectively reduced the effectiveness of alternative revenue sources. A comparative analysis with South Africa reveals that legislative stability, stronger administrative enforcement, effective implementation of international tax standards, and stricter oversight of tax incentives contribute to a broader and more diversified tax base. The study concludes that Zambia's overreliance on PAYE is fundamentally linked to the legal design of its tax framework rather than merely administrative shortcomings. The study recommends the establishment of a comprehensive tax expenditure framework, reform of VAT exemptions and zero-rating provisions, strengthening of mining taxation legislation, enhancement of customs and international tax administration, increased parliamentary oversight of tax incentives, and periodic adjustment of PAYE tax bands. These reforms would contribute to a more equitable, efficient, and sustainable tax system capable of broadening the tax base and reducing dependence on PAYE.
