Class 2 National Insurance
A flat-rate National Insurance contribution historically paid by self-employed people to build entitlement to the State Pension and other contributory benefits. From 6 April 2024, self-employed individuals with profits above the Small Profits Threshold are treated as having paid Class 2 NI without actually making a payment. Those with lower profits can still pay voluntarily to protect their State Pension record.
How it works
Historically, self-employed people paid Class 2 National Insurance as a small flat weekly amount, separate from the profit-based Class 4 contributions, specifically to build up qualifying years towards the State Pension and other contributory benefits such as Maternity Allowance. Since 6 April 2024, most self-employed people no longer make an actual Class 2 payment even though their profits still count towards their National Insurance record.
If your profits are above the Small Profits Threshold, you are treated as having paid Class 2 automatically, without any money changing hands, so your qualifying year for the State Pension is protected without you needing to do anything extra. If your profits fall below the threshold, you do not get this automatic credit, but you can still choose to pay Class 2 voluntarily, which is usually far cheaper than paying voluntary Class 3 contributions to fill the same gap.
Class 2 NI is administered through Self Assessment, with HMRC calculating your position automatically based on the profit figures you report on your tax return, so there is no separate registration or payment process to manage outside of your normal annual filing. Anyone with low self-employment profits who is weighing up whether to pay voluntarily should check their State Pension forecast first to see whether the extra qualifying year is actually needed.
Frequently asked questions
Do I still need to physically pay Class 2 National Insurance?
Only if your profits are below the Small Profits Threshold and you choose to pay voluntarily — above the threshold, you are treated as having paid it without making an actual payment.
How does Class 2 NI affect my State Pension?
Each year you are treated as having paid, or you voluntarily pay, Class 2 counts as a qualifying year towards your State Pension record, alongside years built up through Class 1 employment.
Is Class 2 NI reported separately from my tax return?
No. It is calculated automatically by HMRC from the profit figures on your Self Assessment return, so there is no separate registration or payment process.
