National Insurance credits can help qualifying applicants to fill contribution gaps in their National Insurance record. This can help taxpayers increase their number of qualifying National Insurance years, which may increase the number of benefits they are entitled to, such as the State Pension.

This could happen if someone was:

• employed but had low earnings
• unemployed and were not claiming benefits
• getting National Insurance credits for less than a full tax year
• self-employed but did not pay contributions because of small profits
• living or working outside the UK.

National Insurance credits are available in certain situations where people are not working and therefore, not paying National Insurance contributions. For example, credits may be available to those looking for work, who are ill, disabled or on sick pay, on maternity or paternity leave, caring for someone or on jury service.

Depending on the circumstances, National Insurance credits may be applied automatically or an application for credits may be required. There are two types of National Insurance credits available, either Class 1 or Class 3. Class 3 credits count towards the State Pension and certain bereavement benefits whilst Class 1 covers these as well as other benefits such as Jobseeker’s Allowance.

Taxpayers may also be able to pay voluntary Class 2 or Class 3 National Insurance contributions to protect their entitlement to the State Pension (and in some cases other benefits) if they meet the eligibility requirements. You can only pay voluntary National Insurance contributions to fill gaps for the previous six tax years. The deadline to make payment is 5 April each year. For example, you have until 5 April 2031 to pay voluntary contributions to make up a gap for the 2024-25 tax year.
