The paper assesses the cleanliness of taxpayer returns at the Uganda Revenue Authority (URA) in terms of: (a) completeness – the extent to which taxpayers submit all the required information as specified in the return forms; (b) accuracy – the extent to which the submitted information is correct; (c) consistency – the extent to which taxpayers submit similar information in cases where the same information is required in different types of tax returns, or submitted in the same type of tax return, but for different time periods; and (d) permanence – the extent to which the returns are likely to be later modified by taxpayers.
