In plain words

Taxes are how a government pays for what it does. But a tax does more than raise money. It can make cigarettes dearer, keep out imports, and take more from the rich than from the poor.

Taxes are sorted in two ways: by what is taxed, and by who feels it most.

5 things to know

  1. A direct tax is charged on income or wealth and paid straight to the government by the person or firm: income tax, and corporation tax on company profits.
  2. An indirect tax is charged on spending and collected through sellers: sales taxes such as VAT, excise duties, and tariffs on imports.
  3. A progressive tax takes a larger percentage of income from people with higher incomes. A regressive tax takes a larger percentage from people with lower incomes. A proportional tax takes the same percentage from everyone.
  4. Reasons for taxing: to raise revenue, to discourage demerit goods, to reduce imports, to redistribute income, to influence total demand, and to protect the environment.
  5. Effects: higher income tax leaves households less to spend and may weaken the incentive to work. Higher taxes on profits leave firms less to invest. Higher indirect taxes raise prices.

Worked example

Ali earns $20 000 and pays $2000 in tax. Bea earns $80 000 and pays $20 000. Is the tax progressive, regressive or proportional?

  1. Ali pays 2000 ÷ 20 000 × 100 = 10% of his income.
  2. Bea pays 20 000 ÷ 80 000 × 100 = 25% of hers.
  3. The higher earner pays a larger percentage, so the tax is progressive.

Tips and tricks

  • Judge a tax by the percentage of income it takes, not the amount. A rich person can pay more dollars under a regressive tax and still pay a smaller share.
  • Most indirect taxes are regressive: the tax on a litre of petrol is the same for everyone, so it is a bigger slice of a small income.
