Tax, Spending and Public Services
Why Does Government Collect Tax?
Governments need money to run public services — things such as schools, hospitals, roads, the police and welfare benefits. This money is raised primarily through taxation. In the UK, central government collects most taxes, and some funding is also raised by local councils through the council tax. Without taxation, the government would be unable to provide the services that citizens rely on throughout their lives.
The UK government collects tax in several different ways. Income tax is paid by people who earn above a certain threshold — in 2024–25 the personal allowance (the amount you can earn before paying income tax) was £12,570. National Insurance is another tax on earnings that funds state benefits and the NHS. Value Added Tax (VAT) is charged at 20 per cent on most goods and services and is paid indirectly by consumers when they make purchases. Corporation tax is paid by businesses on their profits.
The four main forms of UK taxation are: income tax (on earnings), National Insurance (on earnings, funds benefits and the NHS), VAT (on most goods and services at 20%), and corporation tax (on company profits). Local government also raises money through council tax on residential properties.
How Is Public Money Spent?
The UK government sets out its spending plans in the annual Budget, presented to Parliament by the Chancellor of the Exchequer. The largest areas of public spending are typically health (principally the National Health Service), social protection (welfare benefits and pensions), and education. Together these three areas account for the majority of government expenditure. Other significant areas include defence, transport infrastructure, and debt interest payments on money the government has borrowed in previous years.
Local government also spends public money, funded partly by central government grants and partly by council tax. Local councils provide services including waste collection, local roads, social care for the elderly and disabled, planning, and early-years education. The budgeting process at both national and local level involves difficult trade-offs: increasing spending in one area often means cutting or holding back spending in another.
Supporters of generous welfare spending argue that a comprehensive welfare state ensures that no citizen is left without support during illness, unemployment, or old age. They contend that investment in welfare reduces poverty and inequality, generates social cohesion, and prevents the long-term costs associated with untreated mental and physical illness. They often point to the post-war settlement that created the NHS and the modern benefits system as evidence of what collective provision can achieve.
Critics of high welfare spending argue that an overly generous benefits system can reduce incentives to work and places a heavy burden on taxpayers and public debt. They suggest that welfare programmes must be means-tested and targeted at those most in need, rather than provided universally, in order to keep costs sustainable. They argue that a growing national debt creates long-term risks for the economy and future generations.
Both viewpoints reflect genuine political values about the role of the state, individual responsibility, and the balance between rights and responsibilities. There is no single “correct” answer to these debates — they form part of the ongoing democratic conversation about how public money should be used.
Health, Education and Elderly Care
The NHS provides healthcare free at the point of use to all UK residents, funded by taxation and National Insurance. It is the largest single item of day-to-day public spending. Supporters of this model argue that universal free healthcare prevents a two-tier system where only the wealthy can afford good treatment. Critics argue that the NHS faces growing demand from an ageing population and that funding pressures require either higher taxes or a different funding model.
Education is funded largely through central government grants to schools, with additional funding channelled through local authorities. Early years, primary, secondary, and further education are all publicly funded, though there is ongoing debate about how university tuition should be funded — whether primarily through student loans, general taxation, or a combination of the two.
The social care system supports elderly and disabled people who need help with daily living. Unlike the NHS, social care is not entirely free at the point of use — individuals may need to contribute to the costs of residential or home care depending on their savings. This gap between NHS funding and social care funding has been a source of significant political debate, with different parties proposing different solutions.
The three largest areas of UK government spending are health (the NHS), social protection (benefits and pensions), and education. Together they typically account for more than half of all public expenditure. Defence is a significant but smaller budget item.
Governments face the challenge of managing risk when making spending decisions. A sudden economic downturn, a public health emergency, or a natural disaster may require extra spending that was not planned in the annual Budget. To manage this risk, governments may hold reserves, borrow money by issuing government bonds (known as gilts), or adjust tax rates. The budget deficit occurs when spending exceeds tax revenues. Accumulated national debt has to be serviced: interest is paid every year, and the debt is either refinanced or reduced through future taxation or spending cuts.
Local councils face similar challenges but with much less room to manoeuvre. Unlike the central government, councils cannot borrow freely or print money. When central government grants are reduced, councils must choose which services to cut or reduce — decisions that directly affect communities and are sometimes highly controversial locally.
