I thank the Deputy very much for the question. The rate at which capital gains tax, CGT, is charged has varied both upwards and downwards since its introduction in 1975. The current standard rate of 33%, which applies to most gains, has been in place since 2012. However, a number of reliefs are already provided for business assets, including retirement relief on the transfer of business or farming assets, revised entrepreneur relief and participation exemption relief. For example, the revised entrepreneur relief provides a reduced rate of CGT for qualifying business assets. The lifetime limit of €1 million of gains on which the relief can be claimed was increased to €1.5 million with effect from 1 January this year. The increased lifetime limit should significantly assist entrepreneurs to grow and scale their businesses or to begin new ventures building on their previous entrepreneurial experience.
As with all taxes, there are options for amending the scope of the tax, including changing the rate of the tax, amending or abolishing existing reliefs or exemptions or considering the introduction of new reliefs and exemptions. However, a narrower base of a tax regime with significant exemptions often requires a higher rate to generate an appropriate yield. A wider base may facilitate a lower headline rate of tax as it applies to a wider set of economic and commercial activities, reduces reliance on any one activity and potentially maintains a more sustainable yield.
On the cost of changing the standard rate of CGT, and this is a legitimate issue people highlight, each 1% reduction or increase is estimated to amount to around €87 million in a full year, assuming no behavioural change. We always have to assume that, although it is harder to factor in. Therefore, a 5% reduction in the standard CGT rate in a single budget would have an Exchequer impact, at least in that budget, of €436 million, assuming no behavioural change. There are also costs to the Exchequer associated with extending the level of relief, as suggested in the question. I put that out to be helpful as people consider budget options.
The programme for Government commits to maintaining a broad tax base to guard against the need for countercyclical fiscal policy in the event of a downturn and to prepare for future budgetary challenges. CGT is an important part of the system to ensure taxation is not focused solely on income tax and that those who benefit from gains in the value of assets are included. As with all taxation measures, it will be kept under review as part of the budget.
