Let’s start with the basics. Taxes are compulsory payments collected by governments from individuals and businesses to fund public services and operations. Think of them as the membership fee for living in a civilised society. They pay for everything from roads and schools to hospitals and defence systems.

There are several types of tax, but the main three are:

• Income tax: A percentage of what you earn from work or investments

• Sales tax/VAT: Added to the price of goods and services (like that extra charge on your mobile credit)

• Property tax: Based on the value of land or buildings you own

Here’s the breakdown. Income tax is typically the most significant burden for individuals. While VAT may cost you 5–15% on purchases, income tax can swallow 20–60% of your entire salary in high-tax countries. That is why this list focuses on personal income tax rates, which are the true heavy hitters.

Why Do African Countries Impose High Taxes?

African nations face unique challenges that often require substantial government expenditure. High tax rates help fund:

• Infrastructure development (roads, electricity, water systems)

• Education systems and literacy programmes

• Healthcare services and disease prevention

• Economic diversification away from dependence on natural resources

• Social safety nets for vulnerable populations

Unlike wealthy nations that can borrow with ease, many African countries rely heavily on tax revenue to finance development projects and essential public services.
