National Insurance & State Pension

National Insurance contributions are often experienced simply as a deduction on a payslip, a line between gross and net pay that reduces the amount you take home. They are, in fact, something more specific: a record of contributions that builds entitlement to the State Pension and certain other state benefits. Understanding your NI record is worth doing, particularly if your working history has included gaps, periods of self-employment, or time spent outside the UK.

How the State Pension works

The full new State Pension in 2025/26 is £230.25 per week, or approximately £11,973 per year. To receive the full amount, you need 35 qualifying years of National Insurance contributions or credits. To receive any State Pension at all, you need a minimum of ten qualifying years.

State Pension age is currently 66 for both men and women. It is scheduled to rise to 67 between 2026 and 2028, and further increases are anticipated in subsequent decades. The exact age at which you will be eligible to draw your State Pension depends on when you were born.

What counts as a qualifying year

A qualifying year is any tax year in which you have paid or been credited with sufficient NI contributions. This includes:

• Years in employment where you earned above the Lower Earnings Limit (£6,396 in 2025/26)
• Years as a self-employed person paying Class 2 contributions
• Years in which you received NI credits, which are awarded automatically in certain circumstances

NI credits: years that count even when you're not working

NI credits protect your State Pension record during periods when you're not in paid employment. They are awarded automatically in a number of situations, including:

• Claiming Child Benefit for a child under 12
• Receiving certain benefits including Jobseeker's Allowance, Employment and Support Allowance, and Carer's Allowance
• Jury service

Checking and filling gaps in your record

You can check your NI record and State Pension forecast through the government's online service at gov.uk/check-state-pension. The forecast shows your current entitlement based on contributions to date, what you'd receive if you continue contributing, and any gaps in your record.

Gaps in your NI record can often be filled by paying voluntary Class 3 contributions. In most cases, each additional year costs around £923 and adds approximately £342 per year to your State Pension for life. For someone who lives 20 years into retirement, that's a return of roughly £6,840 on a £923 investment, a compelling case for filling gaps where they exist.

There are deadlines for filling gaps: typically six years back, though extended windows have applied in recent years for gaps between 2006 and 2018. If you think you may have gaps worth filling, check your record and take action sooner rather than later.

State Pension as a foundation

The State Pension is not a retirement strategy on its own for most people. The full amount provides a modest income relative to most people's working-life expenditure. Its value is as a guaranteed, inflation-linked foundation on which workplace and personal pensions sit. Understanding what you're entitled to, and ensuring you receive the full amount, is a sensible starting point for any retirement planning conversation.
