Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what the tax gap was for (a) income tax, (b) national insurance contributions and (c) capital gains tax in each year since 2009-10.

HM Revenue and Customs published its latest tax gap estimates on 22 October 2015 in Measuring tax gaps 2015 edition, which is available at: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/470540/HMRC-measuring-tax-gaps-2015-1.pdf.

The total tax gap for Income Tax, National Insurance Contributions and Capital Gains Tax for the years from 2009-10 to 2013-14 is set out in Table 1.3 (page 18).

Separate estimates for each of these three components are not available.
