How does pension carry forward work?

Carry forward can increase the annual allowance available for a large pension input, but it is a year-by-year reconciliation—not a blanket extra £180,000.

The short answer

You may be able to use unused annual allowance from the previous three tax years when your pension input exceeds the allowance available for the current year. You must first use the current year's allowance. Earlier unused allowance is then used from the oldest year to the most recent.

HMRC says you do not need to make a separate carry-forward claim. You do need records that support the calculation. See HMRC's carry-forward guidance.

Five conditions to check

1. Use the current year first. Carry forward covers pension input above the annual allowance available for 2026/27.
2. Look back only three tax years. For 2026/27, that means 2023/24, 2024/25 and 2025/26.
3. Confirm scheme membership. You cannot carry forward unused allowance from a year in which you were not a member of a UK registered pension scheme, or a qualifying overseas scheme.
4. Recalculate each year's allowance. Historic tapering, pension input and scheme circumstances can make the unused amount different in each year.
5. Check flexible access. Unused Money Purchase Annual Allowance cannot be carried forward. Other allowance rules may still need a separate calculation.

A simple worked illustration

Assume the 2026/27 annual allowance available before carry forward is £60,000 and total pension input is £80,000. The first £60,000 uses the current year's allowance. The remaining £20,000 could be covered by verified unused allowance from the previous three years, starting with 2023/24.

If 2023/24 has £12,000 unused, that amount is used first. The remaining £8,000 would then come from 2024/25 if enough is available. This illustration assumes no taper, no defined-benefit complication and no MPAA restriction. It does not establish tax relief on a personal contribution.

Carry forward and tax relief are different limits

Carry forward concerns the pension annual allowance and a possible annual-allowance tax charge. It does not automatically increase the tax relief available on personal contributions. Your relevant UK earnings and contribution method still matter. Employer contributions do not follow the same personal-earnings cap, but they still count towards pension input and can affect the annual allowance position.

What to collect before calculating

• Pension input for every scheme for 2026/27 and the previous three tax years.
• Employer and personal defined-contribution payments, including bonus sacrifice.
• Pension input statements for any defined-benefit or hybrid scheme.
• Threshold and adjusted income where the high-income taper could apply.
• Evidence of registered-scheme membership for each earlier year.
• Confirmation of whether flexible pension access triggered the MPAA.

For 2026/27 the standard annual allowance is £60,000. It can be lower for high earners or after some forms of flexible pension access. Employer contributions and defined-benefit growth can count alongside personal payments. Check the current GOV.UK annual-allowance guidance.
