You may have gaps or part years in your National Insurance (NI) record due to a number of reasons – for example, you may have been employed on low earnings, or unemployed but not claiming benefits.  Those who were self-employed or worked abroad may also have gaps in their record.

If your National Insurance record is incomplete you can make up one or more qualifying years by paying voluntary contributions – known as Class 3 contributions. Voluntary Class 2 contributions are for low-income self-employed people.

You’ll need to access your National Insurance record to check if you have any gaps, if you’re eligible to pay voluntary contributions, and how much it will cost. Visit the Check your State Pension website to get a summary of your National Insurance history and gaps you might have.
