Taxation is how governments raise most of the money they spend. Taxes fund public goods and services, redistribute income, and can be used to discourage harmful activities — but the way a tax is designed matters a great deal for fairness.
Why governments tax
- To raise revenue for public spending such as schools, hospitals and roads.
- To redistribute income from higher earners to those in need.
- To discourage harmful consumption, for example taxes on tobacco.
- To help manage the economy as part of fiscal policy.
Direct and indirect taxes
A direct tax is charged on income or wealth and paid straight to the government — for example income tax and profits tax. An indirect tax is charged on spending and collected by sellers — for example VAT (a sales tax) and duties on fuel.
Progressive, regressive and proportional
| Type | How the rate changes |
|---|---|
| Progressive | Higher earners pay a larger percentage of income (e.g. many income taxes). |
| Regressive | Lower earners pay a larger percentage of income (many indirect taxes fall this way). |
| Proportional | Everyone pays the same percentage of income. |
Progressive taxes are often seen as fairer to lower earners, but very high rates may weaken incentives — economists disagree about how strong this effect is.
Zakat: an Islamic system of redistribution
Alongside government taxation, Islam has its own system of wealth redistribution called zakat. Factually, zakat is an obligatory annual payment of a set share (traditionally 2.5%) of a person's qualifying savings and wealth, given to categories of people in need. It is calculated on accumulated wealth rather than only on income, and its purpose is to help the poor and reduce inequality — an idea that overlaps with the redistribution aim of general taxation.
