The following OECD assessment and recommendations summarise chapter 5 of the Economic survey of the United Kingdom published on 27 September 2007.
Globalisation increases the importance of raising tax revenues in the most efficient way so as to maintain competitiveness
Globalisation creates a tension between the need to spend on social safety nets and the need to maintain tax competitiveness, which may reduce revenues. This pressure has encouraged governments to make the corporate income tax system more efficient by cutting statutory corporate tax rates and broadening the base. As the two have offset each other, corporate tax revenue as a share of GDP has been maintained. The United Kingdom was ahead in the game of cutting rates, but has lost ground more recently. It will thus be important to continue with the strategy of broadening the tax base, while cutting the rate. However, there are likely to be limits as to how far this can go, because tax competition also plays out on the base. The United Kingdom’s system of worldwide taxation creates incentives for headquarters to relocate offshore. Thus the government should consider the case for moving to a dividend exemption system of corporate income taxation, which exempts foreign source dividend income from domestic tax. The government has recently published a paper to consult on this issue. Moreover, the complexity of the tax system has increased, in part reflecting a need to respond to increasingly complex financial and commercial structures. However, there is room for simplification.

The degree to which globalisation might undermine the ability to tax corporate income remains uncertain. The location of production is determined by many factors, among which the corporate tax regime is not necessarily the most important. To the extent that globalisation makes it harder to tax mobile factors of production, there may be room to shift taxation onto immobile ones. Property taxation is already high by international comparison, but there is room to raise value added tax (VAT) revenues. By European standards the standard VAT rate is relatively low and includes many exemptions. Thus, there is scope for broadening the base. More radical reform possibilities should also be considered, even though they all have advantages and drawbacks and few have been implemented in other countries.
