Taxes
Taxes fund public goods and services.
About this topic
Taxes are compulsory payments to governments that fund public goods and services such as roads, schools, healthcare and defence, and redistribute income. Direct taxes are on income and profits (income tax, corporation tax); indirect taxes are on spending (VAT or sales tax, excise duties). Systems may be progressive, taking a higher percentage from higher incomes; proportional (flat); or regressive, taking a larger share from lower incomes.
Taxes matter because without them governments could not provide goods that markets underprovide, such as street lighting or national defence, which are public goods. Good taxes are considered fair, simple, certain and efficient. Taxes can also change behaviour: taxes on cigarettes and carbon discourage harmful activity.
Example: under a progressive system with 10 percent on the first 10,000 dollars and 20 percent on income above that, someone earning 30,000 pays 1,000 plus 4,000, so 5,000, an average rate of about 16.7 percent. The marginal rate, 20 percent, applies only to the extra income. A sales tax of 8 percent on a 50 dollar item adds 4 dollars, and is regressive since the poor spend more of their income.
Misconceptions: a higher tax bracket does not make the whole income taxed at the higher rate, only the portion above the threshold. Tip: separate marginal from average rates.
