1 The overall function and purpose of taxation in a
modern economy
1.1 The economic function of taxation
The UK government raises billions of pounds in taxation every year and the system
of taxation and spending by government impacts on the whole economy of a
country.
Taxation policies have been used to influence many economic factors such as
inflation, employment levels, imports/exports, etc.
Taxation policies can also influence the behaviour of individuals and businesses,
which will then have an effect on the economy of the country.
Examples of this influence may be:
Using interest rate changes to encourage either spending or saving.
Encouraging individuals to save and invest, by offering tax incentives such as
Individual Savings Accounts (ISAs) or Venture Capital Trusts (VCTs), etc.
Encouraging charitable giving by offering tax relief on donations and gifts.
Increasing car tax on large cars, to try to cut down CO2 emissions.
Discouraging smoking and drinking alcohol by increasing tax on these goods.
1.2 The social justice purpose of taxation
The type of taxation structure imposed has a direct impact on the redistribution of
the wealth of a country. The main ways of structuring the tax system are listed
below.
Proportional taxation
As income rises, the proportion of tax remains constant. For example, a proportional
tax is one that takes 20% of all earnings regardless of their level.
Progressive taxation
As income rises, the amount of tax also rises by proportion. An example of this
would be 10% on £100,000 of income, rising to 40% on £400,000 of income. The UK’s
system of income tax is an example of a progressive tax system.
