Faced with some of the worse debt levels in over a decade, African countries are struggling to find ways to balance their books. Increasing revenue sources from their citizens is an obvious place to look.
A good starting point for African countries would be to focus on the tax contribution of wealthy citizens. This is because the most under performing taxes across the African continent are those bearing on the income of wealthy individuals, namely personal income and property taxes.
The reasons for this are two fold: People who are better off in some countries often remain invisible to tax authorities. This is even though they have higher tax liabilities. Compare this with citizens who have formal labour contracts. Think of public school teachers or supermarket clerks. Their taxes are withheld by their employers. This makes tax evasion impossible. Most taxes on personal income in Africa are paid by citizens in these forms of employment.
