PUBLIC FINANCE

Public finance is simply how government collects and spends money to provide services for citizens. The Nigerian government needs money to build roads, pay teachers, run hospitals, and maintain security. Government revenue comes from two main sources: tax revenue and non-tax revenue. Tax revenue includes personal income tax, company income tax, and value-added tax (VAT) which Nigerians pay on goods they buy. Non-tax revenue comes from sources like crude oil sales, which historically provided Nigeria's largest income, licensing fees, and government property rentals. The Federal Inland Revenue Service (FIRS) collects taxes in Nigeria. Understanding these sources helps you see how government finances public services and why fiscal policy matters for national development.

Taxation is money the government collects from citizens and businesses to provide public services like roads, schools, and hospitals. Two main types exist: direct taxes are paid straight to government by the person earning income, like Personal Income Tax (PIT) that Nigerians pay monthly from their salaries. Indirect taxes are paid through purchases, such as Value Added Tax (VAT) added when you buy goods in Lagos markets.

Governments use taxation to redistribute wealth, control inflation, and encourage certain behaviors. Direct taxes are fairer because the rich pay more, while indirect taxes are easier to collect but hit poor people harder. The tax incidence shows who actually bears the tax burden—sometimes sellers pass costs to buyers.

Understanding these differences helps you analyze government policies effectively.

Taxation is how government collects money from citizens to provide public services like schools, roads and hospitals. The canons of taxation are basic rules that make taxes fair and effective. These include certainty (taxpayers should know what they owe), convenience (easy payment methods), economy (low collection costs) and productivity (raising enough money).

There are three main tax rates. Proportional taxation charges everyone the same percentage—like Nigeria's VAT at 7.5% on all goods. Progressive taxation increases with income, so wealthier Nigerians pay higher percentages. Regressive taxation takes a larger percentage from poor people than rich people, like fuel taxes that affect everyone equally but hurt lower earners more.

Understanding these differences helps you grasp how government funds work and why some taxes seem unfair.

Taxation is how government collects money to provide services. Direct taxes are paid straight to government—your parents pay income tax on their salaries. Indirect taxes are hidden in prices. When you buy a bottle of Coca-Cola, some money goes to tax without you seeing it separately.

The incidence of tax means who actually bears the burden. With indirect taxes, sellers collect money but consumers feel the pain through higher prices. For example, Nigeria's Value Added Tax (VAT) on goods makes items more expensive for ordinary people, so poor families struggle more than rich ones. This makes indirect taxes regressive—they hurt low-income earners disproportionately.

The composition of taxes refers to the mix government uses. Nigeria relies heavily on oil revenue and indirect taxes rather than income tax. Understanding these differences helps you analyze how government policies affect different groups in society.

Public expenditure refers to money the government spends on behalf of citizens. The government divides this spending into two main types: recurrent and capital expenditure.

Recurrent expenditure covers day-to-day running costs that must be repeated yearly. Think of salaries for teachers and nurses, payment of electricity bills in government hospitals, and maintenance of existing roads. Capital expenditure, however, involves one-time investments in creating new assets like building schools, constructing highways, or establishing power plants.

Consider Nigeria's budget: paying civil servants' salaries is recurrent expenditure, while constructing the Lagos-Ibadan expressway is capital expenditure. Both matter because recurrent spending keeps services running smoothly, while capital spending builds the nation's infrastructure for future growth.

The effects differ significantly—recurrent spending provides immediate relief but doesn't create lasting assets, while capital spending requires patience but generates long-term economic benefits through job creation and improved productivity.

Public expenditure simply means money the government spends to provide services for citizens. This includes paying teachers' salaries, building roads, running hospitals, and maintaining the military. The government budget is a detailed plan showing how much money will be collected through taxes and how it will be spent during a financial year.

National debt occurs when government spends more money than it collects, forcing it to borrow from local banks, international institutions like the World Bank, or other countries. Nigeria's government borrows regularly to fund projects like the Lagos-Ibadan Expressway when tax revenue falls short.

When national debt becomes too large, the government pays interest on borrowed money, leaving less funds for essential services. This creates a cycle where citizens suffer from poor infrastructure and inadequate public services.
