Abstract

This study investigates the influence of value-added tax (VAT) expenditure on VAT effort (VEF) and the VAT compliance gap (VCG) in Nigeria. It uses quarterly time series data spanning 2011 to 2022. The analysis applies the autoregressive distributed lag (ARDL) model alongside the vector error correction model (VECM) to evaluate the relationships between the variables. Findings from the empirical analysis indicate that VAT expenditure significantly reduces VEF while increasing the VAT compliance gap, in both the short term and the long term. Additionally, per capita consumption (PCC) was found to exert a significant negative effect on VEF across both timeframes. The research concludes that VAT expenditure adversely affects VEF and compliance behaviour over time in Nigeria. Considering these negative implications for tax revenue and compliance, it is recommended that the Nigerian government and the Federal Inland Revenue Service should reassess the existing VAT expenditure framework. This reassessment should involve a comprehensive cost–benefit analysis to ensure that tax concessions are limited to cases where the anticipated benefits surpass the costs. Furthermore, efforts should be made to eliminate superfluous tax expenditures to enhance revenue mobilisation and improve compliance.

Abstract

In order to accomplish various macroeconomic goals, including a low unemployment rate, an improvement in balance of payments and enhanced economic growth, numerous countries have employed tax expenditures as one of their fiscal policy instruments over the years. This study examined the effects of tax expenditures on economic growth in the Common Monetary Area (CMA) of Southern Africa from 1985 to 2021. The study focused on the countries with monetary policies that are interlinked with that of South Africa. Tax expenditures, government expenditure, gross capital formation and inflation, and exports and imports data were used. Three models were used in the analysis and the Lagrange Multiplier test indicated that the suitable model was the pooled OLS over the random effects and fixed effects models. The empirical analysis of the research used the pooled OLS model to determine the relationship between the variables. The findings show a positive and significant effect of tax expenditures on economic growth and further suggest that economic growth in the CMA is positively influenced by gross capital formation, inflation and exports, while government expenditure and imports have a negative effect on economic growth. The researcher concluded that tax expenditures as a fiscal policy instrument is effective in promoting economic growth. The policy recommendation is that governments should continue with the tax expenditures subventions; in order to strengthen the usefulness of this fiscal instrument, it needs to be reviewed periodically to establish whether the desired goals are being achieved.

Abstract

This study assesses the effectiveness of tax administration reform on Tanzania’s tax revenue productivity by evaluating how the reforms have influenced the buoyancy of individual taxes using yearly time series data for 1996 to 2017. This period is associated with the introduction of massive reform in the Tanzanian tax administration. The study compares its results with those of Osoro, who evaluated the Tanzanian tax system productivity for 1960 to 1990. To ensure the comparability of results, this study used a similar methodological approach to that used by Osoro. The main objective of this study is to investigate if the reform that took place managed to generate enough tax. The results show that both the tax system and individual taxes are buoyant for the period under review. Our results suggest that the administrative tax reforms that took place have had a significant impact on revenue generation in Tanzania. Thus, we recommend that the government should continue conducting tax administrative reform to cope with the ever-changing business environment.

Abstract

This study aims to establish the way forward for designing and implementing a cooperative compliance programme (CCP) for Kenya. Specifically, the paper seeks to examine the current relationship management framework in Kenya through the lens of a cooperative compliance framework and explore the strategic options for Kenya in designing a CCP to meet its specific needs. The study adopts a mixed research approach: desk research, key informant surveys and focus group discussions. The study identifies gaps in the current relationship management framework that need to be addressed. These included the need to fully understand the unique characteristics of large taxpayers and the context in which tax planning occurs; proper planning and coordination of tax audits by various departments; better handling of tax disputes (which should be centralised and well-coordinated); prompt refund payment; and effective engagement of taxpayers in the formulation of new tax policies and amendment of tax laws. Further, the study proposes strategic initiatives for the design and implementation of a cooperative compliance programme in Kenya. The study concludes by providing a way forward for Kenya, which includes a multi-stakeholder approach to designing a cooperative compliance programme, piloting the programme before full adoption, and implementing the programme through a phased approach.

Abstract

Low tax compliance undermines tax revenue mobilisation in developing countries. Various countries have adopted tax lotteries and rewards as alternative strategies to promoting tax compliance. However, there is limited empirical evidence on how best to design tax lotteries. This study used a lab experiment to study the effect of tax lottery design on compliance. The study used two lottery designs – a lottery of high reward and low probability and a lottery of low reward and high probability. The study found that there was higher compliance (85.2%) for the high reward, low probability lottery compared to the 81.9% for the low reward, high probability lottery; compliance in the control group was 69.8%. Using logistic regression, the study estimated the treatment effect. A lottery of high reward and low probability has a higher treatment effect: 0.1554 compared to 0.1341 for the low reward, high probability lottery. This study concludes that the design of lottery rewards has a significant effect on compliance. It contributes to the literature on the effect of tax lottery design on tax compliance and highlights the need for strategically designing tax lottery rewards to encourage higher compliance.

Abstract

The integration of artificial intelligence (AI) into tax collection processes has emerged as a transformative approach in improving efficiency, accuracy and compliance for national governments. Despite its potential, literature on AI’s role in tax collection, especially in developing countries, remains scarce. This paper makes a contribution to this area by conducting a systematic literature review aimed at investigating the current state of AI implementation in tax collection in developing nations and identifying future research opportunities. The review synthesises findings from twenty selected studies published between 2014 and 2024. The findings indicate that AI facilitates tax compliance through its capacity to automate repetitive tasks, enhancing data processing capabilities and detecting anomalies for targeted enforcement efforts. Moreover, AI tools offer potential in reducing tax evasion by enabling real-time transaction analysis and value chain analysis, closing taxation loopholes and improving fraud detection mechanisms. However, responsible AI use remains paramount, necessitating the establishment of ethical frameworks, transparency measures and mechanisms for accountability to ensure user data protection and adherence to societal norms and legal standards. By compiling insights from diverse studies, this work presents a unique perspective and paves the way for additional research in this emerging field.
