It would be possible, but only at disproportionate cost. If I explain how this relief operates, the Deputy will understand why. The computer records show gross incomes for classes of taxpayers. This relief depends on the number of days a person works abroad. A proportion is deducted from the person's income and he or she is taxed on the balance. For example, if a person's income is £30,000 and he or she spends two-thirds of the year abroad and qualifies for relief, only £10,000 of the income would be taxed. Gross income, therefore, would be shown as £10,000. At the end of the year the person would apply for relief and the Inspector of Taxes would recompute the tax liability on a gross income of £30,000, less foreign earnings relief of £20,000, giving a net amount of £10,000. The person is taxed on that basis and gets a refund of tax. The Revenue Commissioners would have to rejig their accounts at a disproportionate cost to show this. That is the reason the figures are not available. That is why it is not done. When computerisation improves it will be possible to get further information. It would not be cost effective to calculate the figures required by the Deputy.
