The class you pay depends on your employment status and how much you earn, and whether you have any gaps in your National Insurance record.
|National Insurance class||Who pays|
|Class 1||Employees earning more than £157 a week and under State Pension age - they’re automatically deducted by your employer|
|Class 1A or 1B||Employers pay these directly on their employee’s expenses or benefits|
|Class 2||Self-employed people - you don’t have to pay if you earn less than £6,025 a year (but you can choose to pay voluntary contributions)|
|Class 3||Voluntary contributions - you can pay them to fill or avoid gaps in your National Insurance record|
|Class 4||Self-employed people earning profits over £8,164 a year|
