To ask the Chancellor of the Exchequer what his estimate is of the amount of tax unpaid each year since 1995–96, broken down by (a) tax avoidance,(b) tax evasion, (c) late payment and (d) other causes; and if he will make a statement. 
No reliable overall measure is available in relation to tax evasion and avoidance. In the last 10 years, in proportion to the tax involved, tax unpaid at the end of the Inland Revenue's accounting year has approximately halved, and tax remitted or written off has reduced from around 2 per cent. to around 0.3 per cent. The figures for tax unpaid and tax remitted or written off are set out each year in the Inland Revenue's Annual Report, copies of which are in the Library.
