Question to the HM Treasury:

To ask His Majesty's Government what assessment they have made of the revenues which could be raised by levying national insurance upon chargeable capital gains.

National Insurance contributions (NICs) are part of the UK’s social security system. The system, based around the longstanding contributory principle, is centred around paid employment and self-employment, with employers, employees and the self-employed paying into the National Insurance Fund and providing funding for the NHS. Payment of NICs builds an individual’s entitlement to claim contributory benefits which then replace earnings in certain circumstances, for example if someone is unable to work or is retired. Non-employment income is generally excluded from liability to NICs as it is not derived from paid employment. Consequently, individuals with only non-employment income need to pay voluntary NICs in order to build entitlement.

The Government keeps all taxes under review.
