How many years of National Insurance do you need for the UK State Pension, and how can missing years be filled?

Who does this apply to?

This post is general information about the UK "new State Pension". National Insurance and the State Pension are one system for England, Scotland, Wales and Northern Ireland. According to GOV.UK, the new State Pension is for men born on or after 6 April 1951 and women born on or after 6 April 1953. People born earlier get the older basic State Pension. This post does not say who will qualify.

Details

National Insurance (NI) is a contribution paid while working. For some periods you can get a "credit" (a contribution recorded for you) without paying. Not every year counts towards a pension. A year that counts is called a "qualifying year".

• Minimum: GOV.UK says you need at least 10 qualifying years on your NI record to get any new State Pension.
• Full amount: GOV.UK says that if your NI record started after April 2016, you need 35 qualifying years for the full rate. With fewer years the amount can be lower.
• Older records: If you were "contracted out" before 2016, you usually need more than 35 years. Contracted out was an old, pre-2016 option where part of your NI went to a workplace or private pension instead of the additional State Pension (or you paid less NI). People who paid into the old Additional State Pension may get a "protected payment". The official forecast is the way to see your own figure.
• Amount: The full weekly amount changes every year. For the current figure see the GOV.UK page.
• How a year counts: Working and paying NI, getting NI credits (for example while unemployed, ill, a parent or a carer) or paying voluntary contributions can make a year a qualifying year. Time living or working abroad may sometimes count; this post does not cover specific countries such as Turkey.

What are voluntary (Class 3) contributions?

Class 3 is an optional NI payment used to fill gaps in your record.

• Rate: GOV.UK gives £18.40 a week for the 2026 to 2027 tax year. For the previous 2 tax years you pay those years' original rates; for earlier years you pay the 2026 to 2027 rate. The rate changes every April.
• Time limit: GOV.UK says you can only pay for the past 6 years. Each gap year has its own deadline (5 April). GOV.UK's example: for 2025 to 2026, the deadline is 5 April 2032. Older years generally cannot be paid for; ask HMRC about any exception.
• Who cannot pay: You cannot pay if there are no gaps, or if the deadline has passed.

Things to be aware of

• GOV.UK says to check first whether you are eligible for NI credits.
• Time abroad: GOV.UK says that from 6 April 2026 the rules for Class 3 for time abroad became stricter. You now need 10 years in a row of UK residence or 10 years of qualifying NI contributions in total (it used to be 3). Class 2 can no longer be paid for time abroad. For transitional rules and the application form (CF83) see the GOV.UK abroad page.
• The NI record only shows contributions up to the start of the current tax year. Isle of Man contributions may not be shown.

What can you do?

1. Check your NI record on GOV.UK. You may need to sign in and prove your identity. The record can show gaps, the estimated effect of voluntary contributions and their cost.
2. Get your State Pension forecast online. Alternatives: the HMRC (UK tax office) app, form BR19 (a postal application) or a phone call. BR19 and phone are for people more than 30 days from State Pension age. People already getting the pension cannot use the online service.
3. Questions that can be put to the official body: "Is there a credit for this gap?", "Would a voluntary payment for this year increase my pension?", "What is the deadline?"
4. Who to ask (according to GOV.UK): the Future Pension Centre if you are below State Pension age; the Pension Service if you have reached it; the International Pension Centre if you live or work abroad and are at State Pension age or within 6 months of it.
5. For free independent help see the Citizens Advice State Pension page, which also points to MoneyHelper and Age UK.
