The class you pay depends on your employment status or if you have a gap in your National Insurance record.
|National Insurance class||Who pays|
|Class 1||Employees earning more than £149 a week and under state pension age - they’re automatically deducted by your employer|
|Class 1A or 1B||Employers pay these directly themselves on their employee’s expenses or benefits|
|Class 2||Self-employed people - you don’t have to pay if you earn less than £5,725 and apply for a ‘small earnings exception’|
|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 £7,755|
