Gaps in National Insurance contributions

National Insurance and the Settlement Application

National Insurance is not one of the published settlement requirements. Those are the qualifying period, the continuous residence requirement in Appendix Continuous Residence, the Life in the UK test at ages 18 to 64, the requirements of the particular route, and Part Suitability of the Immigration Rules.

A National Insurance record can still carry information the application uses, because it records where and when someone was paid:

• Employment dates: a contributions record carries the periods in which someone was paid in the UK. The Home Office continuous residence guidance names an employer letter stating when employment started as one form of independent evidence of a date of entry.
• Self-employment: Class 2 and Class 4 contributions record self-employed activity, which matters on routes where self-employed income is part of the requirement. See our self-employment evidence guide.
• Salary verification: On the Skilled Worker route, the settlement requirement is a document from the sponsor confirming the salary, under paragraph SW 24.2. Payslips and P60s record the same figures.

Why Gaps Arise

GOV.UK lists the situations that produce gaps in a National Insurance record. A person may have been:

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

The last of these overlaps with the settlement rules: our guide to working remotely from abroad covers how those days are counted for continuous residence, which is a separate question from whether contributions continued. GOV.UK also advises checking eligibility for National Insurance credits — given, for example, during periods on certain benefits or caring for children — before deciding to pay voluntary contributions. Our guide to maternity and parental leave covers the statutory leave position.

Checking the Record

A National Insurance record can be checked online through a personal tax account on GOV.UK. This shows:

• How many qualifying years you have
• Any gaps in your record
• Whether you can make voluntary contributions to fill gaps
• Your projected state pension amount

GOV.UK says to contact HM Revenue and Customs if a National Insurance record appears to be wrong. See our guide to National Insurance numbers.

Voluntary Contributions

Gaps can often be filled with voluntary contributions, which affect the State Pension rather than anything in the immigration rules. The published terms are:

• Rates for 2026 to 2027: £3.65 a week for Class 2 and £18.40 a week for Class 3.
• Deadline: voluntary contributions can be paid for the past 6 years, with a deadline of 5 April each year. GOV.UK gives the example that gaps for the 2025 to 2026 tax year can be made up until 5 April 2032.
• Which rate applies: the current rate is usually paid. Class 2 for the previous tax year, and Class 3 for the previous 2 tax years, are charged at the original rate for those years; anything earlier is charged at the 2026 to 2027 rate.
• Who cannot pay: GOV.UK names people with no gaps in their record (unless they are getting Class 3 credits and are eligible to pay Class 2), married women or widows paying reduced rate National Insurance, and anyone past the deadline for the period concerned.
• Whether it helps: GOV.UK states that voluntary contributions “do not always increase your State Pension”, for example where someone was contracted out, and directs people below State Pension age to a State Pension forecast and the Future Pension Centre, and people at State Pension age to the Pension Service. The GOV.UK voluntary National Insurance pages carry the detail, and our guide to pensions for visa holders covers the wider picture.

The State Pension Figures

The published position is:

• 10 qualifying years: GOV.UK says usually at least 10 are needed to get a State Pension at all.
• 35 qualifying years: needed for the full rate of the new State Pension where the National Insurance record started after April 2016. Where it started before April 2016 and the person was contracted out, GOV.UK says more than 35 years will usually be needed.
• £241.30 a week: the full rate of the new State Pension. It rises each year by the highest of average wage growth in Great Britain, Consumer Prices Index inflation, or 2.5%.

Years of qualifying contributions are not the same as years of residence, and neither is the same as the settlement qualifying period. See our guide to settlement and the State Pension.

The Citizenship Application

National Insurance is not one of the published requirements for British citizenship either. GOV.UK sets those out as: having lived in the UK for 5 years and held indefinite leave to remain for 12 months; not more than 450 days outside the UK in the 5 years before the application and not more than 90 days in the last 12 months; passing the Life in the UK test; proving knowledge of English, Welsh or Scottish Gaelic; being over 18; intending to continue living in the UK; and being of good character. It costs £1,839: £1,709 to apply and a £130 citizenship ceremony fee.

Our guide to UK tax covers how PAYE and self-assessment record contributions.
