Taxes are compulsory monetary payments made by individuals and businesses that are levied by the state. The state collects taxes for five main reasons: to raise revenue, redistribute income, control spending, maintain economic stability, and satisfy specific objectives. There are two main types of taxes - direct and indirect. Direct taxes are paid directly by individuals and companies, while indirect taxes are paid by one entity but the economic burden is passed on to another. Some examples of direct taxes are income tax and corporation tax, while indirect taxes include value added tax and customs duties. An effective tax system should balance factors like equality, certainty, convenience, flexibility and stability to avoid overburdening citizens.
