National Insurance reforms: What’s being reviewed and why

Several aspects of National Insurance (NI) are to be reviewed as part of the Government’s recently announced 2026 tax update package. Whilst there are no proposed rate changes, NI remains one of the more complex areas of the UK tax system, so it is no surprise that the Government want to make it easier to navigate and ensure it is fit for purpose.

While most of the proposals are administrative rather than financial, they form part of a wider tax modernisation agenda focused on simplification, compliance and improving how the system operates for individuals and employers alike. Employers should also note the increasing focus on payroll governance, record keeping and the efficient administration of tax obligations.

Voluntary National Insurance contributions

As part of its wider review of the tax system, the Government has launched a call for evidence on voluntary National Insurance contributions (NICs). These are payments which individuals can choose to make to fill any gaps in their NI record to ensure they are entitled to the State Pension and certain other benefits.

The gaps in their NI record could be because the individual was:

• Unemployed
• Working overseas
• Employed with low earnings
• Self-employed but did not make contributions due to small profits

The Government is using this call for evidence to request feedback on how effectively the current system operates and where problems or difficulties are encountered. Responses will help inform future policy decisions aimed at making the process clearer and more accessible.

For some individuals, voluntary NICs can be a valuable planning tool, helping to improve State Pension entitlement where gaps exist in their contribution record. However, whether making additional contributions is beneficial will depend on individual circumstances and should be considered carefully before taking action.

NIC easements for internationally mobile individuals

Although this area affects a more specialist audience, it is particularly relevant for multinational businesses, internationally mobile employees and overseas directors carrying out limited UK duties.

Non-resident directors who come to the UK for a small amount of board meetings or to carry out limited UK duties, but are based in countries without a social security agreement, may be able to do this without needing to make any NICs. Whilst this is an existing practice that is often relied upon in situations where a director cannot obtain the relevant Certificate of Coverage, the Government are formally recognising this to provide clarity and ensure the rules are applied consistently.

Further consideration is also being given to the approach surrounding the easement that allows some employees working in a country with no social security agreement to return to the UK for short periods without additional Class 1 NICs becoming payable. Currently, there is a directors exemption from NIC if the director spends a limited amount of time in the UK (for which there are set day thresholds that their trip(s) must satisfy).

For affected employers and employees, the proposed clarification should help reduce uncertainty and provide greater confidence when managing international assignments and cross-border working arrangements.

Consultation on NI debt recovery processes

HMRC is consulting on proposals to align National Insurance recovery rules with Income Tax. Currently, HMRC have up to 20 years to assess Income Tax liabilities, but once they have made an assessment, there is no time limit on recovering the debt. NIC debts, however, are no longer recoverable after six years unless HMRC takes specific action to protect the debt or reaches an agreement with the employer. This can create complexity when Income Tax and NIC liabilities arise from the same issue.

The consultations propose that the statutory time limits for debt recovery relating to NICs would be:

• 4 yearsif reasonable care has been taken
• 6 years if there are careless errors
• 20 years if there are deliberate errors
• 12 years for some offshore matters

It is also proposed within the consultation that the time limit is reduced from six years to four years for claims which relate to overpaid NICs.

Although these proposals would not change how NICs are calculated, they could increase the importance of maintaining accurate payroll records and resolving historic payroll issues promptly. If implemented, they would create greater consistency between Income Tax and NIC administration while potentially increasing scrutiny of payroll compliance processes.
