What taxes are, what they pay for, how different countries run their public services, and why debates about taxes are really debates about what kind of society we want.
Young children can begin to understand the idea behind taxation and public services through the simple concept of sharing. The core instinct is that some things work best when we share them — a well for a village, a park for a town, a school for a neighbourhood. Children do not need the word 'tax'. But they can understand that when everyone puts in a little, everyone can enjoy something bigger than anyone could afford alone. This is the whole principle of public services and the taxes that pay for them. At this age, the goal is to build the instinct that shared things matter and that looking after them is everyone's job. No materials are needed.
Schools and hospitals are free — they do not cost anything.
Schools and hospitals do cost money — teachers, doctors, buildings, and books all cost a lot. The reason you do not pay directly is that your family and other families in the country pay a little bit — called tax — to the government, and the government uses all of that money to pay for schools and hospitals for everyone. This is why people say 'free at the point of use' — you do not pay at the door, but someone has paid.
Paying tax means the government is taking your money.
Tax is more like everyone putting in a little so that we can all have things nobody could afford alone — schools, hospitals, fire services, roads, clean water. You pay a bit, but you get much more in return — things you use every day without noticing. Paying tax is one way of being part of a community.
Taxes are payments that people and businesses make to the government to fund public services. They are the main way that modern states finance the work of government. Without taxes, there would be no state-funded schools, hospitals, roads, police, fire services, pensions, or defence. The idea of taxation in some form is almost universal — every functioning state raises revenue somehow. But the amount, the types, and the fairness of taxes are among the most important political questions in any country.
Income tax (on what people earn from work); corporate tax (on business profits); sales tax or VAT (added to things people buy); property tax (on homes and land); import duties (on goods coming into the country); capital gains tax (on profits from selling investments); inheritance tax (on large fortunes passed down); and specific taxes on fuel, tobacco, alcohol, and other items. Countries combine these in different ways.
This varies by country but typically includes healthcare, education, social security (pensions, unemployment benefits), defence, police and courts, infrastructure (roads, bridges, public transport), scientific research, diplomacy, and government administration itself. In wealthy countries, social protection and healthcare are usually the largest areas of spending.
Tax rates vary enormously. Nordic countries collect the most — around 40-45% of their economic output in taxes — and fund extensive welfare states, universal healthcare, free higher education, and generous pensions. The UK collects about 33%. The US collects about 25%. Many developing countries collect less — sometimes 15% or less — which limits what they can spend on public services.
A progressive tax takes a higher percentage from people who earn more (income tax is usually progressive). A flat tax charges the same percentage to everyone. A regressive tax takes a higher percentage from people who earn less (sales tax can be regressive, because poor people spend more of their income). Most tax systems combine these elements. Who pays tax and how much is one of the most important questions in a society.
Tax evasion is illegal (hiding income to avoid tax). Tax avoidance is technically legal but often controversial — using legal structures to pay less tax than the government intended. Large companies and wealthy individuals often employ experts to minimise tax through complex international structures. The Panama Papers and Pandora Papers exposed how widespread this is.
The saying 'no taxation without representation' captures something important. Taxes are the main connection between citizens and government. When citizens pay for services, they feel entitled to hold government accountable. Countries that fund themselves mostly through natural resources (oil, minerals) often have weaker accountability because governments do not need to persuade citizens to pay tax.
Tax is politically charged. Different political views disagree about how high taxes should be, who should pay them, and what they should fund. Present the facts and the main debates without pushing students toward a specific view. Help them develop their own thinking about what they believe a good society should look like — and how it should be paid for.
The government makes its own money, so it does not really need taxes.
Governments can print money, but printing more money usually does not solve the problem — it typically causes prices to rise (inflation) and can cause the economy to collapse. Countries that have tried this (Venezuela, Zimbabwe, Weimar Germany) have ended in economic disaster. Real spending requires real resources, and those come mostly from taxes. Borrowing is possible for a while, but debts must be paid back. Taxes are the main and most reliable source.
If I do not want a public service, I should not have to pay for it.
This would make public services impossible. The point of shared services is that everyone pays, so that everyone has access when they need it. You may never need the fire service — but you benefit from it being there. You may not have children in school now, but schools educate the workers, doctors, and leaders of the future. Paying tax is about being part of a community, not a consumer buying specific services.
Countries with low taxes are always richer and freer.
The evidence does not support this. Many of the world's wealthiest countries (Norway, Denmark, Sweden, Germany, Netherlands) have high taxes and strong public services. They also score very highly on freedom, democracy, and individual rights. Meanwhile, some low-tax countries have weak services, poor health, and struggle with inequality. The relationship between tax levels and outcomes is complex — there is no simple 'lower taxes means better' rule.
Tax avoidance by companies is fine because it is legal.
Tax avoidance is technically legal, but the fact that something is legal does not mean it is right. Many tax avoidance strategies use loopholes to pay far less than the tax was designed to collect — shifting profits to tax havens, using complex ownership structures, or exploiting gaps between different countries' rules. When big companies avoid tax, ordinary people and smaller businesses make up the difference — or services get cut. There is a strong and growing movement to close these loopholes and make tax avoidance much harder.
Taxation is where political philosophy meets practical economics. Understanding its main theoretical foundations and contemporary debates is essential for secondary teaching.
Economists distinguish public goods (like national defence, clean air, or public broadcasts) — which are non-excludable (you cannot prevent people from benefiting) and non-rivalrous (one person's use does not reduce another's) — from private goods. Markets generally underprovide public goods because no one can be charged individually. This is the classic economic justification for taxation: to provide goods that benefit everyone but that markets would not produce on their own. Paul Samuelson's seminal work formalised this in 1954.
Modern taxation developed alongside modern states. Before the 20th century, most states had small tax takes — often 5-10% of national income. World Wars I and II dramatically expanded state spending and tax takes. The post-WWII welfare state (expanding in most wealthy democracies through the 1950s-70s) institutionalised high taxation and extensive social services. Since the late 1970s, there has been pressure to reduce tax rates in many countries, though tax takes as a percentage of GDP have not fallen as much as advertised.
OECD data shows that tax/GDP ratios vary from around 45% (Denmark, France) down to about 25% (US, some developing countries). What matters as much as the headline rate is the composition. Nordic countries rely heavily on VAT and payroll taxes alongside income tax. Anglo-Saxon countries rely more on income tax. Many developing countries rely heavily on trade taxes (tariffs) because administering income taxes requires strong state capacity. Taxes on capital (inheritance, wealth, property) have declined significantly across the OECD since the 1980s, a shift Piketty and others have criticised.
Tax systems can reduce inequality (through progressive income tax and transfers) or worsen it (through regressive sales taxes and capital gains loopholes). The post-WWII era saw highly progressive tax systems in Western democracies (US top marginal income tax rate was 91% in the 1950s). Since the 1980s, top rates have fallen substantially across most OECD countries, contributing to rising inequality. Piketty and Saez have documented this trend in detail.
Globalisation has enabled a form of tax competition in which countries lower rates to attract investment and wealthy taxpayers. The most extreme form is 'tax havens' — jurisdictions (Cayman Islands, British Virgin Islands, Luxembourg, Delaware) that offer very low rates and high secrecy. The Panama Papers (2016), Paradise Papers (2017), and Pandora Papers (2021) exposed the scale of offshore wealth. The OECD-led global minimum corporate tax deal (2021, implementation ongoing) represents an attempt to address this. Progress has been significant but incomplete.
The Laffer curve (Arthur Laffer, 1970s) is the idea that beyond a certain point, higher tax rates produce less revenue because people work less or avoid/evade more. The existence of a peak is uncontroversial; its location is much debated. The famous claim that rates were 'beyond the Laffer curve' was used to justify major tax cuts in the 1980s; the evidence that these were revenue-positive is weak. More recent research (Piketty, Saez, Diamond) suggests the revenue-maximising top rate is probably around 70-80% — much higher than current rates.
A common saying in civic education is that budgets are moral documents. What a society chooses to fund — and not fund — reveals what it values. Comparing health spending, defence spending, education spending, and welfare spending across countries reveals different priorities. Engaging students with budget documents can produce genuine insight into political values. The welfare state: the modern welfare state combines insurance (health, unemployment, pension) and redistribution (means-tested benefits). Its most articulate defenders argue that it makes markets work by providing a floor, encouraging risk-taking, and reducing the instability that would otherwise threaten the political order. Its critics argue that it creates dependency, distorts labour markets, and is fiscally unsustainable as populations age. The actual evidence on welfare state effects is more nuanced than either side suggests.
Taxation is one of the most politically polarised topics in civic education. Present the major positions fairly, use evidence from multiple contexts, and resist taking sides. Help students develop their own views based on their own values and evidence they find persuasive.
Cutting taxes always increases economic growth.
The evidence for this is weaker than often claimed. Some tax cuts — particularly of very high rates or of taxes that distort behaviour — may produce modest growth effects. But the idea that tax cuts reliably produce strong growth is not supported by studies of US and UK tax cuts since the 1980s. Nordic countries with high taxes have strong economies. The relationship between tax rates and growth depends on many factors, including what the cuts replace, how revenue is used, and the institutional context. The simple equation 'lower tax equals higher growth' is not empirically sound.
Tax avoidance by corporations is legal, so it is not a real problem.
The line between legal tax avoidance and tax evasion is technical, not moral. Tax avoidance often involves structures designed specifically to exploit loopholes in ways legislators did not intend. The result is that large corporations pay far less tax than was meant to be collected from them — sometimes effective rates under 5%, while small businesses and individuals pay full rates. This shifts the burden of funding public services to those with fewer resources. The response has been international coordination (the OECD minimum tax) and new domestic legislation. Treating legality as moral endorsement misses the deeper question of what the tax system is for.
The government can always print more money instead of raising taxes.
Governments with their own currency can create money, but unlimited money creation produces inflation, which is itself a kind of tax (it reduces the value of savings held in that currency). In extreme cases, it produces hyperinflation and economic collapse (Zimbabwe, Venezuela, Weimar Germany). Moderate money creation has legitimate uses, but it is not a substitute for tax revenue. Sustainable public spending requires sustainable revenue, which mostly means taxes.
High taxes mean low freedom.
The claim that high taxes reduce freedom depends heavily on what is meant by freedom. On a narrow definition (freedom from state interference), high taxes do reduce freedom. On a broader definition (the actual capacity to make meaningful choices), high taxes that fund universal education, health care, and social protection can expand freedom for most people. Nordic countries have high taxes but consistently rank among the freest societies in the world on most global freedom indices. The relationship is more complex than the claim suggests.
Key texts accessible to students: Thomas Piketty's 'Capital and Ideology' (2019) provides extensive historical analysis of tax systems. Emmanuel Saez and Gabriel Zucman's 'The Triumph of Injustice' (2019) examines how the US tax system evolved — accessible and sharp. For UK debate: Richard Murphy's 'The Joy of Tax' (2015). For the theory: Richard Musgrave's classical work remains influential; more recently, Joseph Stiglitz's 'The Price of Inequality' (2012). On tax havens: Nicholas Shaxson's 'Treasure Islands' (2011) and 'The Finance Curse' (2018) are accessible investigative accounts. On the Nordic model: 'The Nordic Way' (various authors) provides an overview. Data resources: the OECD tax database (oecd.org/tax), the Tax Policy Center (taxpolicycenter.org), and the Tax Justice Network (taxjustice.net) all provide excellent ongoing analysis.
