Recent changes to Class 2 National Insurance contributions (NICs) were meant to simplify things for self-employed taxpayers.

Instead, some are facing confusion, incorrect charges, and silence from HM Revenue & Customs (HMRC).

The rule change that caused the problem

From the 2024/25 tax year, most self-employed individuals no longer needed to pay Class 2 NICs, provided their profits were above £6,725.

Instead, HMRC now automatically credits these individuals to protect their entitlement to benefits like the State Pension.

This was introduced as part of the 2024 Autumn Budget, with the aim of reducing the administrative burden.

For those with lower profits, Class 2 NICs remain voluntary, and can still be paid to maintain a full National Insurance record.

What has gone wrong?

Despite the change, HMRC’s systems have not caught up. Reports from the Association of Taxation Technicians (ATT) suggest that self-employed individuals are receiving letters from HMRC incorrectly stating they owe Class 2 NICs, often for £179.40.

There appear to be three main types of letter:

• Version one – Confirms the Class 2 amount is zero, which matches the original return. In these cases, the letter is redundant.
• Version two – Incorrectly adds a £179.40 Class 2 NIC charge that should not be there, and must be removed.
• Version three – Incorrectly adds the £179.40 twice, inflating the tax liability.

HMRC has acknowledged the issue and is working to resolve it, but has not given a timeline.

What should you do now?

If you have recently filed a Self-Assessment return for 2024/25, check your HMRC account carefully.

If Class 2 NICs have been added unexpectedly, or you have received one of the letters above, do not ignore it.

Review your online Self-Assessment summary to check for incorrect charges, and hold off on paying any unexpected amounts until HMRC resolves the issue

Should you pay Class 2 NICs voluntarily?

Even though Class 2 NICs are no longer compulsory for many, they still matter.

If your income is below the £6,725 threshold, paying voluntarily may help you qualify for the State Pension or other contribution-based benefits.

You need at least 10 qualifying years of NICs to receive the State Pension, and usually 35 years for the full amount (though this may vary depending on your situation).

If you are unsure whether you have got gaps in your record, it is worth checking.

Do you have doubts about your Class 2 NIC position and if you should be paying voluntarily?
