How National Insurance Affects Your State Pension
What the law says
Qualifying for the State Pension An individual qualifies for the State Pension if they reach pensionable age (currently 66 for both men and women, rising to 67 between 2026–2028) and satisfy the contribution conditions — i.e. they have a sufficient National Insurance (NI) record.
What counts as a qualifying year A qualifying year is a tax year during a person's working life in which they have paid (or are treated as having paid) the required amount of National Insurance contributions, supplemented by credits or credited earnings.
Old State Pension (reached State Pension age before 6 April 2016)
- Women generally required 39 qualifying years and men 44 qualifying years for 100% of the basic State Pension.
- A minimum of 25% of the basic State Pension required at least 10 qualifying years for women and 11 for men.
New State Pension (reached State Pension age on or after 6 April 2016)
- Introduced by the Pensions Act 2014.
- Each qualifying year added after 5 April 2016 adds 1/35 of the weekly rate of the new State Pension to a person's entitlement.
- A person cannot pay Class 3 NICs once they have reached the full amount of the new State Pension, or for years after they have reached State Pension age.
Stopping NI contributions at State Pension age Most people between age 16 and State Pension age pay contributions into the National Insurance scheme, which enable them to claim benefits such as the State Pension. Once State Pension age is reached, contributions cease.
HMRC guidance / practice
NI contributions build entitlement HMRC confirms that NI contributions paid during working life build up a person's NI record, which determines the amount of State Pension they receive. Gaps in the record can reduce entitlement.
Voluntary contributions to fill gaps Where there are gaps in NI contributions, it may be possible to pay voluntary Class 2 or Class 3 NICs to increase the State Pension amount. However, HMRC advises contacting DWP first to check the impact, as paying voluntary NICs does not always increase the State Pension — particularly for those who were contracted out of the additional State Pension before 6 April 2016.
Refund of Class 3 NICs that did not increase State Pension HMRC recognises the complexity of the transitional new State Pension rules and allows Class 3 NICs paid prior to 6 April 2017 to be refunded where the payment did not in fact increase the person's State Pension (subject to specific conditions, including having contracted-out employment on their NI record).
No NI contributions after State Pension age Once you reach State Pension age, you stop paying NI contributions. Your employer(s) or pension provider(s) should not deduct NI contributions from your pay or pension after that point.
Checking your NI record HMRC's Personal Tax Account (introduced December 2015) allows anyone to check their NI record digitally, including qualifying and deficient tax years, and to check their State Pension forecast.
Home Responsibilities Protection (HRP) For periods when a person was not working (e.g. caring for children or a disabled person), Home Responsibilities Protection could reduce the number of qualifying years needed for a full State Pension, or NI credits could be awarded — protecting State Pension entitlement without requiring paid contributions.
In summary: Your NI record — built up through paid contributions, credits, or voluntary contributions — directly determines whether you qualify for the State Pension and how much you receive. You stop paying NI contributions when you reach State Pension age (currently 66).

Most people between 16 and the State Pension age pay contributions into the National Insurance scheme. These contributions enable individuals to claim National Insurance benefits, such as the State Pension. There’s a brief summary of the classes of National Insurance contributions at NIM00002 in the National Insurance Manual.
The Pensions Act 2014 introduced the new State Pension (nSP) for all those who reached State Pension age (SPa) on or after 6 April 2016. Those who were contracted-out of the additional State Pension at any point before 6 April 2016 may now be precluded from paying Class 3 National Insurance contributions (NICs) for periods before 6 April 2016. A person’s entitlement to nSP is determined by their starting amount. It is calculated by comparing their entitlement to State Pension under the old and n
HRP is available for complete tax years from 6 April 1978 to 5 April 2010. From 6 April 2010, National Insurance credits for parents and carers replaced HRP. For information on these credits, see NIM41250 onwards. HRP is provided for those precluded from regular employment because they were caring for a child or a sick or disabled person and if the claimant received certain benefits, such as Child Benefit for a child under age 16 or the person for whom they cared received certain disability bene
Persons who reached State Pension age (SPa) prior to 6 April 2010 In simple terms, a qualifying year is a tax year during a person’s working life in which they have paid (or are treated as having paid) the required amount of National Insurance contributions supplemented by credits, or credited earnings. Most of these credits are linked to benefit entitlement and are awarded by DWP but some, referred to as non-benefit credits, are administered by HMRC. See NIM41010. For persons who reached SPa pr
