A simple NIC change has triggered major tax confusion

The 2024/25 tax year brought a key change for self-employed taxpayers: those earning more than £6,725 are no longer required to pay Class 2 National Insurance Contributions (NICs).

Rather than simplifying matters, the change has led to errors in HM Revenue & Customs’ (HMRC’s) systems and a growing number of incorrect tax demands.

What the reform was meant to achieve

Under the new rules, qualifying self-employed individuals automatically receive National Insurance credits to secure their entitlement to benefits such as the State Pension.

This was introduced to reduce bureaucracy and streamline the process of tax compliance.

Those with lower profits can still pay Class 2 NICs voluntarily to ensure they build up a sufficient contribution record.

The issue in practice

Reports from professional tax bodies, including the Association of Taxation Technicians, show that HMRC has been issuing letters with inaccurate Class 2 NIC demands.

These errors fall into three main categories:

• Letters correctly confirming that no Class 2 NICs are due.
• Letters wrongly charging £179.40 despite eligibility for exemption.
• Letters repeating the incorrect charge twice.

These errors are affecting the tax liabilities shown in online accounts, and in some cases, prompting taxpayers to make unnecessary payments.

Actions to take now

If you have recently submitted a Self-Assessment return, you should review your HMRC online account for any unexpected Class 2 NIC charges.

Do not make payment if the figures do not align with your actual position.

While HMRC is aware of the issue, it has not yet implemented a fix or issued refunds.

Why voluntary contributions remain important

If you fall below the £6,725 threshold, you may still benefit from paying Class 2 NICs voluntarily.

This helps ensure you maintain a complete record towards your State Pension entitlement.

At least 10 qualifying years are needed to receive any State Pension, and 35 years are typically required for the full amount.
