Some interesting statistics were published by the Oxford University Centre For Business Taxation (or the Centre For Business Non-Taxation, as Richard Murphy wittily calls them. But there's bad blood between them because Murphy calls them biased and they call him uninformed).
Anyway - here's some stuff from Oxford University, that was compiled from HMRC anonymised data. My comments are in square brackets.
- In 2010 the UK had the lowest corporate tax rate in the G7 and the 7th lowest corporate tax rate in the G20.
- For more than 25 years, the UK CT rate has been well below the G7 average.
- However, UK CT revenue has consistently been above the G7 average. [This is because we have a wide tax base to which we apply a relatively low tax rate.]
- The top 1 percent of all companies by size pay 81% of UK CT.
- By far the largest share - 87% - of CT is paid by multinational groups (only 13% is paid by companies from purely domestic operations).
- Financial services companies (i.e banks) paid £46 billion of CT in 2007/08, falling to £36 billion in 2009/10 [presumably due to tax losses incurred in 2008/09 - but £36 billion is still a BIG figure].
- Around 14% of all companies making a book profit (i.e. that have positive Earnings Before Interest & Tax in their statutory accounts) do not show a charge for tax in their accounts [there can be several reasons for this: group relief from other group companies; tax deductions in excess of profit due to specific reliefs such as R&D credits; non-taxable income such as gains from the disposals of subsidiary companies. However, tax avoidance is another possibility].
- There is evidence that the largest 100 companies in each sector pay less tax (as a percentage of EBIT) than the sectoral average [which does seem to add some weight to the argument from campaigners that the biggest companies participate in some form of tax avoidance.]
- Real Estate and Mining companies pay the highest tax rates (that is, they pay the highest percentage of their trading profits over as tax) at 35.9% and 34.1% respectively. [That actually surprises me, given the heat from tax campaigners over extractive industries "stealing from the poor through tax avoidance". I would expect that some of this is due to sector specific taxaxtion rather than just CT, but does seem to show that mining is the last sector that needs country-by-country reporting].
Out of interest, the lowest is post and communications at 6.67% of trading profits paid to HMRC as tax. Utilities also look very low at 12.5%.
Banks are 6th highest (out of 30 sectors) with 21.9% of their trading profits paid to HMRC. [That quite surprises me too. I didn't expect the banks to be quite so tax paying, given that the sector is dominated by big players who have the resources to try to avoid tax if they want to.]
