State Pension gaps: spotting missing National Insurance years early
Before you rely on the full new State Pension, check your NI record. Gaps are common after career breaks — and sometimes fixable.
By Eleanor Mair
The full new State Pension requires a set number of qualifying National Insurance years. Career breaks for childcare, overseas work, or periods of low earnings can leave gaps that only become obvious when you request a forecast.
Request your State Pension forecast through the government service and download your NI record. Mark years with no contributions or credits. Some gaps can be filled with voluntary Class 3 contributions; whether that is worthwhile depends on how many years you lack and how long you have until State Pension age.
Self-employed clients sometimes discover incomplete Class 2 histories after a year of thin profits. Employees who moved between employers quickly can also find missing credits if payroll errors went unnoticed.
We fold State Pension forecasts into retirement income mapping so private pensions and ISAs are sized against what the State will actually pay — not an assumed full amount.
