The minimum amount of National Insurance-linked earnings a person must achieve in a tax year—through paid, treated‑as‑paid or credited National Insurance contributions—so that the year counts as a qualifying year towards State Pension entitlement.
This is a statutory concept in UK social security law (Social Security Contributions and Benefits Act 1992 and the parallel Northern Ireland Act). The qualifying earnings factor for a tax year equals 52 times that year’s lower earnings limit (LEL). An individual’s “earnings factor” is built from Class 1 NICs (employees) and, where applicable, Class 2 NICs (self‑employed), Class 3 voluntary NICs and NI credits. Earnings between the LEL and the primary threshold give rise to NICs “treated as paid”.
The term is central to entitlement under the pre‑6 April 2016 basic State Pension and remains relevant to transitional “starting amount” calculations for the new State Pension and to certain legacy contributory and bereavement benefits.
Usage and meaning are consistent across England and Wales, Scotland and Northern Ireland. The term is not used in Irish (Republic of Ireland) social welfare law, which relies on PRSI contribution conditions rather than a qualifying earnings factor.
