(2) how many calls the Tax Evasion Hotline received in each month since its inception;
(3) what proportion of calls received by the Tax Evasion Hotline resulted in prosecutions for tax evasion in each month for which figures are available.
HM Revenue and Customs does not currently have a separate record of the cost to administer the Tax Evasion Hotline in each month since its inception. These data could be collated only at disproportionate cost.
The number of calls received by the Tax Evasion Hotline each month since its inception are detailed in the following table. HM Revenue and Customs advertising campaigns can significantly affect the volume of calls received in any month.
HM Revenue and Customs are unable to provide this information. The exemption at section 31(1)(a) of the Freedom of Information Act on ‘law enforcement’ also provides an exemption from disclosure in respect of the proportion of calls received resulting in prosecution.
