Customs administrators worldwide are mandated to mobilize national revenue collections through the assessment and collection of applicable duties and taxes on all imports and exports. One of their primary concerns following the ratification of the Trade Facilitation Agreement is the need to optimise revenue collections while simultaneously upholding trade facilitation. This research assesses trade facilitation implications on government revenue mobilization in developing countries with a particular emphasis on Zimbabwe. The paper adopts a qualitative approach, capturing several subjective elements including the examination of the Critical Success Factors for enhanced revenue collection as well as the evaluation of trade facilitation as a solution to customs revenue leakages. Purposive sampling was employed to collect data from employees working in the Customs Division at the Zimbabwe Revenue Authority. Eighty questionnaires were distributed to participants working in Beitbridge, Chirundu, Forbes border posts and the Robert Mugabe International Airport targeting Customs Senior Managers, Customs Middle Managers, Revenue Supervisors and Revenue Officers as key respondents. Data was analysed using the Statistical Package for Social Sciences version 29. This analysis focused on four dimensions of trade facilitation, which includes port efficiency, customs environment, regulatory environment, and electronic-business. The findings indicate that trade facilitation reforms, when executed appropriately in conjunction with enhancements in electronic-business, port efficiency, customs environment and the regulatory framework, can effectively augment revenue collection. Regulatory environment improvements are key in influencing increasing revenue collection and should be prioritised in resource allocation for the achievement of best possible outcomes. We recommend ‘continuous refresher training’ on trade facilitation awareness targeting all stakeholders in ports of entry, accompanied by the implementation of robust risk management strategies as well as intensified implementation of integrity management tools.
