Gender responsive budgeting is a key instrument to track how governments are investing in advancing gender equality and equity. While most studies of gender responsive budgeting work so far have examined the expenditure side of the budget, the revenue side is equally important. In this Economic Paper, Nite Tanzarn looks at the revenue and tax system in Uganda, a country that has moved from analysis to action in gender responsive budgeting. This case study will show policy-makers in ministries of finance worldwide how government revenue collection practices affect men and women differently, and how to build an awareness of gender into financial policy.
