The new provisions involve a re-working of the National Insurance contributions legislation, which is already heavily amended by the Social Security Act 1998 and the Social Security Contributions (Transfer of Functions, etc.) Act 1999. So for clarity, Schedule 9 restates sections 5, 6, 8 and 9 of the Contributions and Benefits Act completely. It also deals with the consequences for contracted-out pension schemes and for the NICs revenue allocated to the NHS.
Section 74 and Schedule 10 make corresponding provision for Northern Ireland. Because they are parallel provisions, they are not referred to in the commentary below.
