Uganda still lags behind in its tax collections at the domestic level. For most of the commodities the tax collection effort is not more than 5 percent relative to the statutory rate of 18 percent. This results into a situation where the government has to rely a lot on foreign financing. From the analysis, there is a lot of improvement where URA can be able to increase its tax effort. this could be achieved by targeting commodities that are under-taxed and excluding food items for equity purposes. Increasing domestic collection would also result into less over reliance on taxing a few commodities especially fuel which is interlinked with a lot of other sectors and could indeed harm growth in the long-run. We also find that the tax effort on imports is sufficient. However, import duties on fuel remain very high and this could be a symptom of the poor domestic tax collection.
