Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate he has made of the amount of income tax revenue lost to the public purse from workers being wrongly categorised as self-employed in each year since 2009-10.

The Government is committed to tackling false self-employment. HM Revenue & Customs (HMRC) take a risk-based approach to investigating employers who may have misclassified individuals for tax purposes. In these cases, HMRC establish the facts and take steps to ensure the right tax and National Insurance contributions are paid.

Income Tax and National Insurance contributions lost due to false self-employment are part of the tax gap related to employers. HMRC publish an assessment of the tax gap: www.gov.uk/government/statistics/measuring-tax-gaps.

A separate estimate of the tax gap relating to false self-employment is not available.
