Class 2 National Insurance – Changes from April 2024

Who Pays?

As of 6 April 2024, most self-employed people no longer need to pay Class 2 NICs if their profits are above the Small Profits Threshold (SPT) of £6,725.

However:

  • If your profits are above the SPT, you will receive NI credits automatically without needing to pay Class 2 NICs.

  • If your profits are below the SPT, you can choose to pay voluntary Class 2 NICs to protect your entitlement to benefits.

2024–25 Rate:

  • Voluntary Class 2 NICs: £3.45 per week

What Do Class 2 NICs Count Towards?

Voluntary Class 2 contributions can help you qualify for:

  • Basic State Pension

  • Maternity Allowance

  • Employment and Support Allowance (ESA)

  • Bereavement Support Payments

Class 4 National Insurance – Still Required

Who Pays?

You must pay Class 4 NICs if your annual profits are £12,570 or more.
2024–25 Rates:

  • 6% on profits between £12,570 and £50,270

  • 2% on profits over £50,270

This rate has decreased from the previous 9% in 2023–24, helping to reduce the NIC burden on self-employed earners.

How Do I Pay These NICs?

Both Class 4 NICs and any voluntary Class 2 NICs are typically paid through your Self Assessment Tax Return.

If you're not registered for Self Assessment but want to make voluntary Class 2 contributions, HMRC will issue a payment request if applicable.

Exemptions from Class 2 NICs

Even before the 2024 change, certain individuals were exempt from paying Class 2 NICs. These exemptions still apply. You are not liable for Class 2 NICs if you:

  • Are an examiner, moderator, or invigilator

  • Run a business involving land or property

  • Are a minister of religion without a salary or stipend

  • Make investments for yourself or others (not as a business and without fees/commission)

If you fall into these groups, you may still wish to voluntarily pay Class 2 NICs to ensure your State Pension record remains intact.
