Taxes, Public Spending and the Government Budget
Governments raise most revenue from taxes on income, spending and profits, and a tax rarely stays where it is placed: the side of the market that can walk away pays less of it. Spending above revenue means borrowing, and the debt that builds up is judged against the size of the economy rather than in pounds.
What a learner can do afterwards
- Classify a tax as progressive, proportional or regressive and justify it with worked figures
- Explain who really bears a tax on a good by comparing the elasticities of supply and demand in that market
- Distinguish a deficit from debt and say why debt is quoted as a share of GDP

Governments pay for roads, schools, and hospitals with taxes. The main kinds are taxes on earnings, taxes on spending, and taxes on company profits. A fair tax question is always who really pays. If buyers cannot walk away while sellers can, the tax reaches shoppers through a higher price. The side that can walk away pays less.
Sort taxes with simple incomes of 100, 500, and 1000 coins. A 10 coin bill on each is regressive: 10 percent of 100 but only 1 percent of 1000, so lower incomes carry the bigger share. A flat 10 percent everywhere is proportional: the same share from all. Rates that climb with income are progressive: the bigger share falls on higher incomes. Work the shares before you label.
A deficit is a one-year gap when spending beats tax revenue. Debt is the pile of all past gaps added up, minus any surpluses. Big economies quote debt as a share of GDP so countries of different sizes compare fairly. A deficit of 3 coins means little alone: against a GDP of 10 it is heavy, against 1000 it is light.
Who really pays a tax sits with the side that adjusts least. Compare supply elasticity with demand elasticity: the less elastic side bears more, since its quantity moves less when price moves. Demand elasticity alone cannot settle it. And who hands the tax money to the government is a different question from who bears it.
Work the shares, watch who can walk away, and read debt against the economy.

Tax types and who pays them
Taxes help fund roads, education and hospitals. Common taxes apply to earnings, purchases and business profits. Ask who ultimately bears each tax. When buyers respond less to price changes than sellers, buyers bear more through higher prices. Practise classifying taxes as progressive, proportional or regressive using calculations for incomes of 100, 500 and 1000 coins.
What public spending provides
Government spending funds services and projects, including teachers' pay and railway construction. Higher spending requires more revenue or borrowing, and voters debate this balance. Education and transport can support future growth; pensions and clinics support people's needs now. These purposes can overlap. Examine budget entries for investment and protection, then consider who benefits most.
Annual deficits and accumulated debt
A budget deficit occurs when annual spending exceeds revenue. Debt reflects accumulated borrowing, with surpluses able to reduce it. Expressing debt relative to GDP helps compare differently sized economies. A 3-coin deficit equals 30 percent of a 10-coin GDP, but only 0.3 percent of a 1000-coin GDP.
Elasticity and the burden of a tax
Elasticity measures responsiveness to price changes. Compare demand elasticity with supply elasticity to determine tax incidence: the less responsive side bears more. If petrol buyers respond less than suppliers, drivers bear most of a fuel tax. If concert-ticket buyers respond more than sellers, sellers bear more of that tax. Demand elasticity by itself is insufficient.
