Frequently Asked Questions

What is pension carry forward and how does it work?

Pension carry forward allows you to make use of any unused annual pension allowance from the previous three tax years to make a larger contribution in the current tax year. This is particularly beneficial for high earners or those with fluctuating income who want to maximize their tax relief. You must first fully utilize your current year’s allowance (£60,000 for 2026/27) before using unused allowances from earlier years.

How many years of unused pension allowance can I carry forward?

You can carry forward unused allowances from up to the three previous tax years. For the 2026/27 tax year, this means you can utilize unused allowances from 2023/24, 2024/25, and 2025/26. Unused allowance from a year further back than three years is lost forever.

Do I need to have been a member of a pension scheme in the past to use carry forward?

Yes. To carry forward unused allowance from a previous tax year, you must have been a member of a registered pension scheme at some point during that year, even if no contributions were actually made. If you were not a member of a scheme in a given year, your allowance for that year is £0 and cannot be carried forward.
