Primary data was gathered using structured questionnaires. The population of this study was managers, owners and employees of selected SSB in Kasubi market. A stratified sampling method was employed to determine a sample of 626 study participants from the entire population. The data obtained was analyzed quantitatively using descriptive statistics. The presentation methods of statistics used included frequency distribution, tables and bar graphs. The study established a significant correlation between taxation and the growth of the SSB sector. From the findings of the study it was concluded that high tax rates have a significant effect on the growth of SSB. The better the tax rates the more the SSB grow. If the tax rates are high, the profit margins of the firms become too small to improve on the scale and size of the business as the SSB will hardly have enough capital to re-invest. It can be also concluded that better tax policies have a positive effect on the growth of SSBs thus the more favorable the tax policies are, the better the growth trends for SSB. Types of taxes are concluded to have a significant effect on the growth of SSBs. Since the types of tax are determined by the level of income that the SSB receive, if better and favorable types of taxes are adopted, then they would boost expansion of SSB. It is the recommendation of this research report that more friendly tax policies be employed for start-up businesses such as tax holiday, or introducing a growth limit with a level that is sufficiently stable to sustain payment of taxes. The study is further of the view that the Tax agency, URA, need to review its taxation procedures as well as heightened research on firm’s management procedures, the role of taxation policy and distribution of taxes in micro enterprises
