National Insurance
From ACT Wiki
UK tax.
(NI).
National insurance is a UK tax paid by individuals and employers, nominally to secure certain benefits such as a state pension on retirement or reaching a certain age.
In practice, the links between funding pensions and other benefits, gaining entitlement to these benefits, and the amounts of National insurance contributions paid, are not always consistent or direct.
Sometimes abbreviated to NIC, National Insurance Contributions.
