| Abstract: | Abstract: This paper attempts to examine key aspects of the Sudanese tax system, paying particular attention to the impact of the recent trade liberalization on government revenues. An eclectic method of analysis is utilized. The results show that the Sudanese tax system as a whole is not buoyant or elastic; the same applies for its major handles. The liberalization reform did not appear to have enhanced revenue productivity and stability in the country. This result indicates the presence of substantial slacks in tax collection and tax evasion. The analysis also shows that tax evasion is the main problem facing tax administration; on average, it stands at about 53 per cent of actual tax yield and 33 per cent of the potential tax yield inclusive of the underground economy's gross domestic product (GDP). Assessment of the determinants of trade revenue suggests that the yield of trade tax has improved due to liberalization; however, the marginal benefit of tax evasion is still considerable. The findings imply that a committed tax reform is crucial for augmenting tax revenue yield as well as for fiscal consolidation and macroeconomic stability. |
