Learn how to top up NIC contributions before the extended deadline in London.

Voluntary National Insurance Contributions – Extended Deadline to 5 April 2025

Individuals with gaps in their National Insurance record, those approaching State Pension age, self-employed individuals with low profits, and UK nationals living abroad.

Explains when making voluntary National Insurance Contributions (NICs) may increase entitlement to benefits, including the State or New State Pension.

Missing qualifying years can reduce your State Pension entitlement permanently. The current extended deadline presents a time-limited opportunity to fill historic gaps.

In certain circumstances it can be beneficial to make voluntary National Insurance Contributions (NICs) to increase your entitlement to benefits, including the State or New State Pension.

Standard Time Limits for Voluntary NICs

Usually, HMRC allow you to pay voluntary contributions for the past 6 tax years. The deadline is 5 April each year.

Extended Opportunity – April 2006 to April 2017

However, there is currently an opportunity for people to make up for gaps in their NICs for the tax years from April 2006 to April 2017 as part of transitional measures to the new State Pension.

This deadline was set to expire on 5 April 2023 but had been extended until 31 July 2023. The deadline has now been further extended until 5 April 2025 to help allay continued concerns that the existing deadline would not have allowed many taxpayers to fill gaps in their NIC records. HMRC’s helplines have been struggling to meet the demands for information and processing claims to pay additional NIC contributions.

HMRC has also confirmed that all relevant voluntary NIC payments will be accepted at the rates applicable in 2022-23 until 5 April 2025.

Who Should Consider Making Voluntary NICs?

You might want to consider making voluntary NICs if:

  • You are close to State Pension age and do not have enough qualifying years to get the full State Pension.
  • You know you will not be able to get the qualifying years you need to get the full State Pension during the remainder of your working life.
  • You are self-employed and do not have to pay Class 2 National Insurance contributions because they have low profits.
  • You live outside the UK but want to qualify for benefits.

Real-World Application

For example, an individual approaching retirement with missing qualifying years between 2006 and 2017 may be able to increase their State Pension entitlement by topping up those years before 5 April 2025. However, the financial benefit will depend on existing contribution history and proximity to retirement.

Important Considerations

If you fall within any of these categories, it may be beneficial to get a State Pension forecast and examine whether you should consider making voluntary NICs to make up missing years, known as topping up.

Not everyone will benefit from making voluntary NICs and a lot depends on how close you are to retirement age and your NIC payments to date.

Deadline Risk

The extended deadline of 5 April 2025 is time-limited. After this date, the ability to fill gaps going back to 2006 may no longer be available under the current transitional arrangements.

Considering Topping Up Your National Insurance Record Before the Extended Deadline?
