This study examined the extent of tax stamp evasion among categories of micro-business owners in Twifo-Atti Morkwa and Hemang Lower Denkyira districts in Ghana. Data were collected from taxpayers in the study area who qualify for tax stamps and interview schedule was used for the collection of the data from the respondents. In total, 305 taxpayers were interviewed. The study employed chi squared statistics as the analytical tool. Overall, the study found a significance association between extent of tax stamp evasion and categories of micro-business owners. The partitioned pearson’s chi2 revealed that there is a significant association between fashion designers and full tax stamp evasion; a significant association between partial tax stamp evasion and traditional caterers and a significant association between no tax stamp evasion and beauticians (hairdressers and barbers). This study strongly recommends that the Ghana Revenue Authority’s policy intended to curb tax evasion in the informal sector should be customized to meet the unique features of the various categories of the informal business operators. Besides, Ghana Revenue Authority should pay more attention to fashion designers in the informal sector.
