2025 UPDATE: New UK State Pension Top-Up Rules

Over recent years, eligible UK expats and Aussies that worked in the UK had been granted additional time to top up their UK State pension entitlements, with the deadline on rules impacting the amount able to be topped up was initially slated for 5 April 2023 and subsequently pushed back to 31 July 2023. The significant level of enquires received by HMRC and their ballooning turnaround times prompted them to extend the date again to 5 April 2025. There was no indication from HMRC in the lead-up to this date that it would be extended again, and now that the deadline has passed, many UK expats will find their maximum National Insurance (NI) contribution top-up amounts severely limited.

Given we’re now the other side of 5 April, here’s the state of play under the new rules, and what to do next.

Are You Eligible for the UK State Pension?

To determine if you qualify for the UK State Pension, you’ll need to assess your National Insurance record. If you have ever worked in the UK and paid National Insurance (NI) contributions, you will have an entitlement to the UK State Pension, even if you are not a UK national. To be eligible to claim a pension, you must have contributed a minimum ten years’ worth of NI contributions. If you have not reached this minimum, you can make voluntary contributions to fill any gaps, provided you have lived and worked in the UK for three continuous years.

The NI rate you pay to top up (Class 2 or Class 3) depends on a few factors – more on that below. Class 2 rates are preferable as they present a cheaper option compared to Class 3. After you top up your NI record and reach the UK State Pension age, you will receive a pension based on the number of NI contributions you have made. A maximum Basic State pension requires 35 years of contributions.

Previous UK State Pension Top-Up Rules

Previously, if eligible, you could make a one-off backdated NI contribution to cover missed years from 2006-07 onwards. By topping up your NI contributions, you made a small initial investment for a significant return once you reach the state pension age. This meant you could purchase a total of 16 years’ worth of NI contributions to fill gaps in your record ensuring you meet the minimum 10-year threshold, increasing your entitlement.

UK State Pension Top-Up Rules (as of 5 April 2025)

From 5 April, you will only be able to make voluntary backdated contributions for the past 6 years, as opposed to the previous maximum of 16. This rule change effectively reduces the amount that you can increase your entitlement or potentially render you ineligible for a UK State Pension if you have fewer than four qualifying years on your NI record.
