There has been considerable discussion recently about whether the government should introduce a property tax on high value properties. The government, finding it difficult to reduce the public-sector deficit and yet determined to do so, is looking for additional measures to reduce government expenditure or raise tax revenue.
But would it favour a mansion tax as a means of raising additional revenue?
The imposition of such a tax is favoured by both Liberal Democrats and the Labour Party. It is strongly opposed, however, by Conservatives. But just what would such a tax look like and what are the arguments for and against it?
One alternative would be to impose a one-off tax on property valued over a certain amount, such as £2 million. Alternatively it could be levied only for as long as the government is seeking to make substantial inroads into the deficit.
Another would be to add one or more bands to council tax. At present, council tax in England is levied in 8 bands according to the value of a person’s property. The highest band is for property valued over £320,000 in 1991 prices, with the amount of tax due for each band varying from local authority to local authority. (Average UK house prices in 2012 are 135% higher than in 1991.) In Scotland the bands are lower with the top band being for property valued over £212,000 in 1991 prices. In Wales, there is an additional band for property valued over £424,000, but properties are valued in 2003 prices, not 1991 prices.
With low top bands for council tax, people in mansions end up paying the same as people in much more modest property. It would be relatively easy to add additional bands, with the top band applying only to property worth, say, over £1 million or more.
The arguments in favour of a mansion tax are that it is progressive, relatively easy to collect, hard to evade and with minimal disincentive effects. The arguments against are that it would make the tax system ‘too progressive’, would not necessarily be related to an individual’s ability to pay and could have substantial disincentive effects.
The progressiveness of the UK tax system is illustrated in the chart, which looks at the proportion of income paid in direct, indirect and all taxes by quintile groups of households – that is, households grouped into five equal sized groups ranked from lowest to highest gross income. (Click here for a PowerPoint of the chart.)
The following articles look at the debate as it has raged over the past few weeks. Try to unpick the genuine arguments from the political rhetoric!

A campaign to introduce a tax on disposable plastic bags in England has been launched by various pressure groups, including The Campaign to Protect Rural England (CPRE), Keep Britain Tidy, the Marine Conservation Society and Surfers Against Sewage. Plastic bags, they maintain, litter streets and the countryside and pollute the seas, where they cause considerable damage to marine life.
They propose a tax of 5p per bag, which would be passed on to consumers. Such a levy has already been introduced in Wales in October 2011. As a result, plastic bag use in Wales has dropped dramatically (see also the full report from the Welsh Government). The Scottish Government and the Northern Ireland Assembly are also planning introducing similar charges.
Many other governments have introduced taxes, charges or bans on plastic bags and many more are considering introducing such measures. Ireland introduced a 15 euro cent charge on single-use plastic bags as far back as 2002 and saw a 94% reduction in plastic bag use (328 per person per year to 21). The charge was raised to 22 euro cents in 2007 after bag use rose to 30 per person.
Other countries have banned plastic bags altogether: some, such as Rwanda and Somalia have banned all plastic bags; others, such as China and South Africa have banned very thin bags; others, such as Italy, have banned non-biodegradable ones.
In the USA, various states or districts have introduced levies and in the EU, where more than four billion bags are thrown away each year, the European Commission will soon publish proposals for limiting the use of plastic bags.
So what are the arguments for limiting the use of plastic bags? Why is it not enough to leave things simply to the market? And if the use of plastic bags is to be reduced, what’s the most efficient way of doing so? Are there any problems with alternatives to plastic bags? The following articles and reports consider these questions?

Barclays’ Chief Executive, Bob Diamond, has resigned following revelations that Barclays staff had been involved in rigging the LIBOR in the period 2005–9, including the financial crisis of 2007–9.
So what is the LIBOR; how is it set; what were the reasons for Barclays (and other banks, as will soon be revealed) attempting to manipulate the rate; and what were the consequences?
The LIBOR, or London interbank offered rate, is the average of what banks report that they would have to pay to borrow from one another in the inter-bank market. Separate LIBORs are calculated for 15 different lending periods: overnight, one week, one month, two months, three months, six months, etc. The rates are set daily as the average of submissions made to Thomson Reuters by some 15 to 20 banks (a poll overseen by the British Bankers’ Association). Thomson Reuters then publishes the LIBORs, along with all of the submissions from individual banks which are used to calculate it.
Many interest rates around the world are based on LIBORs, or their European counterpart, EURIBORs. They include bond rates, mortgage rates, overdraft rates, etc. Trillions of dollars worth of such assets are benchmarked to the LIBORs. Thus manipulating LIBORs by even 1 basis point (0.01%) can result in millions of dollars worth of gains (or losses) to banks.
The charge, made by the Financial Services Authority, is that Barclays staff deliberately under- or overstated the rate at which the bank would have to borrow. For example, when interbank loans were drying up in the autumn of 2008, Barclays staff were accused of deliberately understating the rate at which they would have to borrow in order to persuade markets that the bank was facing less difficulty than it really was and thereby boost confidence in the bank. In other words they were accused of trying to manipulate LIBORs down by lying.
As it was the LIBORs were rising well above bank rate. The spread for the one-month LIBOR was around 1 to 1.2% above Bank Rate. Today it is around 0.1 to 0.15% above Bank Rate. Without lying by staff in Barclays, RBS and probably other banks too, the spread in 2008 may have been quite a bit higher still.
The following articles look at the issue, its impact at the time and the aftermath today.

Let’s face it – no-one likes paying tax! After all, to see your monthly pay decline by £1000 through taxation and national insurance has got to hurt. Yet, taxation and national insurance contributions are essential sources of government revenue to finance benefits and public and merit goods.
However, with so much attention given to the UK’s ‘culture of dependency’, many people are increasingly angry with having to pay so much in taxation to see it being spent by the government on individuals who in some cases choose not to work and at the same time seeing other rich people paying so little in taxation. The increase in the top rate of tax received a lot of coverage. Although it did make the tax system more progressive, there were many concerns that it would lead to lower growth, a lack of innovation and enterprise and increased tax evasion and avoidance, as the super-rich were being hit with phenomenal tax bills. The post on the 50p income tax available here is worth looking at again to think about the effect that taxes have on incentives.
The issue of tax avoidance is by no means new, but with a large budget deficit in the UK, tax avoidance by the super-rich has become something that everyone has an opinion on. The average household has seen its income squeezed more and more, as the government continues its efforts to cut the deficit. The fact that the super rich are avoiding sometimes millions in taxation, while the average household struggles to pay even the basic rate of tax, creates a rather contentious issue. The Chief Secretary to the Treasury, Danny Alexander, has said that the basic rate of tax could be cut by 2p in the pound if tax avoidance came to an end. He commented to the BBC’s Sunday Politics Programme that:
‘We have to make sure that everybody, especially the rich and famous, are paying their fair share of tax…These sorts of schemes that save wealthy people potentially tens of millions of pounds in tax, they are paid for by everybody else… If we could narrow the tax gap in this country by a quarter we could reduce income tax for every basic rate payer by 2p in the pound.’
This would clearly have some very positive effects on some of the poorest people living in the UK.
There is a variety of tax avoidance schemes available and the one receiving the most attention at present is the Jersey-based K2 scheme, which Jimmy Carr and others are thought to be using. The Public Accounts Committee will be reporting on the problem of using private companies to pay salaries, as a means of avoiding income tax and national insurance contributions.
If tax avoidance could be stopped, or at least reduced, then not only could basic rate tax payers benefit, but it might go some way to cutting the budget deficit, giving the government more flexibility in stimulating the economy. According to HMRC, tax avoidance and evasion cost the economy some £42 billion – enough to pay off one-third of Britain’s budget deficit.

Questions
- What are the key principles of a good tax system?
- Explain how taxation affects the incentive to work?
- What is the difference between tax evasion and tax avoidance?
- Using indifference analysis, illustrate the effect of a cut in the basic rate of income tax. How does it affect the decision to work more or less? You should consider the income and substitution effects in your answer and which rate of tax (if any) an individual is paying.
- Why is tax avoidance of such concern at the moment? Think about the current state of the economy.
- What are taxes and national insurance contributions used to pay for?
- To what extent do you think tax avoidance is a natural consequence of any tax system?
Recently there have been calls from business leaders and Conservative politicians to scrap the UK’s 50% income tax rate, which is paid on taxable incomes over £150,000. The 50% income tax rate is thus paid by top earners, who comprise around just 1% of taxpayers.
And yet the government receives about 30% of income tax revenue from this 1% – and this was before the introduction of the 50% rate in April 2010. (In fact, with the marginal national insurance rate of 2%, top earners are paying an effective marginal rate of 52%.)
One argument used by those who favour reducing the 50% rate is that the rich would pay more income tax, not less. There are four reasons given for this. The first is that people would be encouraged to work harder and/or seek promotion if they knew they would keep more of any rise in income. The second is that fewer rich people would be encouraged to leave the country or to relocate their businesses abroad. The third is that more people would be encouraged to work in or set up businesses in the UK. The fourth is that there would be less temptation to evade taxes by not declaring all income earned or to find clever ways of avoiding tax.
These arguments were put forward in the 1980s by Art Laffer, an adviser to President Reagan. His famous ‘Laffer curve’ (see Economics (8th edition) Box 10.3 or Economics (7th edition) Box 10.4) illustrated that tax revenues are maximised at a particular tax rate. The idea behind the Laffer curve is very simple. At a tax rate of 0%, tax revenue will be zero – but so too at a rate of 100%, since no-one would work if they had to pay all their income in taxes. As the tax rate rises from 0%, so tax revenue would rise. And so too, as the tax rate falls from 100%, the tax rate would rise. It follows that there will be some tax rate between 0% and 100% that maximises tax revenue.
Those arguing that a cut in the top rate of income tax would increase tax revenue are arguing that the 50% rate is beyond the peak of the Laffer curve. But this is an empirical issue. In other words, to assess the argument you would need to look at the evidence as, theoretically, the peak of the Laffer curve could be below or above 50%. Indeed, some argue that the peak is more likely to be at around 75%.
The following podcasts and articles consider the arguments. As you will see, the authors are not all agreed! Consider carefully their arguments and try to identify any flaws in their analysis.

On 27 June 2012, Arthur Laffer appeared on the BBC Today Programme to discuss the Laffer curve and its implications for UK income tax policy. You can hear it from the link below

Questions
- Explain how a cut in income tax could lead to an increase in tax revenue.
- Distinguish between the income effect and the substitution effect of a tax cut. Which would have to be bigger if a tax cut were to increase tax revenue?
- If, in a given year, the top rate of tax were raised and tax revenue fell, would this prove that the economy was now past the peak of the Laffer curve?
- What would cause the Laffer curve to shift/change shape? To what extent could the government affect the shape of the Laffer curve?
- If the government retains the 50% top tax rate, what can it do to increase the revenue earned from people paying the top rate?
- What other objectives might the government have for having a high marginal income tax rate on top earners?
- Investigate the marginal income tax and national insurance (social protection) rates in other countries. How progressive are UK income taxes compared with those in other countries?
There has been considerable discussion recently about whether the government should introduce a property tax on high value properties. The government, finding it difficult to reduce the public-sector deficit and yet determined to do so, is looking for additional measures to reduce government expenditure or raise tax revenue.
