East African countries continue to pursue markedly different approaches to taxing employment income, with significant variations not only in personal income tax rates but also in mandatory social security, health insurance and housing contributions that determine how much workers ultimately take home.
A review of tax systems across Uganda, Kenya, Ethiopia, Tanzania, Rwanda, Burundi and South Sudan shows that Uganda applies the region’s highest top marginal personal income tax rate at 40%, while South Sudan has the lowest at 20%.
Kenya and Ethiopia impose maximum rates of 35%, while Tanzania, Rwanda and Burundi cap their highest rates at 30%.
Although headline income tax rates offer one measure of the tax burden, economists note that employees’ actual deductions depend on a broader combination of payroll taxes and statutory contributions required under each country’s labour and social protection systems.
Uganda’s highest tax band has remained unchanged since 2012. Its progressive income tax structure includes a tax-free monthly threshold before rates rise through several brackets to a maximum of 40%.
Workers also contribute 5% of their salaries to the National Social Security Fund, while employers contribute an additional 10%.
Kenya’s top income tax rate is lower at 35%, but formal-sector employees face additional compulsory deductions, including contributions to the Social Health Insurance Fund, the Affordable Housing Levy and the National Social Security Fund.
Combined, these deductions make Kenya one of the region’s highest-taxed labour markets for many salaried workers despite its lower headline tax rate.
The country’s tax policy has become the subject of political and economic debate. Business groups have argued that reducing the highest personal income tax rate could stimulate employment and increase disposable income, while the government has sought to preserve tax revenues needed to finance public spending.
Proposals to raise the tax-free income threshold and lower the highest tax rate were considered during discussions on the Finance Bill 2026 but were ultimately rejected by lawmakers.
Ethiopia introduced major reforms to its personal income tax system in 2025, increasing tax-free thresholds and adjusting income bands to reduce the burden on lower-income earners while maintaining a top rate of 35%.
The changes were widely viewed as making the country’s tax structure more progressive.
Elsewhere in the region, Tanzania, Rwanda and Burundi maintain maximum income tax rates of 30%, although workers’ overall payroll deductions differ because of varying pension and social insurance requirements. Rwanda, for example, is gradually increasing pension contributions under ongoing reforms aimed at strengthening its social security system.
South Sudan continues to levy the region’s lowest top personal income tax rate at 20%, although its formal payroll and pension systems remain less developed than those of its regional neighbours.
The comparison highlights how statutory income tax rates alone do not fully reflect workers’ overall tax burdens.
Across East Africa, mandatory pension contributions, health insurance schemes and other payroll deductions increasingly play a central role in determining employees’ net earnings, as governments seek to expand social protection while maintaining public finances.
