Pension Carry Forward: How to Use Unused Allowances in 2026/27

Pension carry forward is one of the most powerful but underused tools in UK retirement planning. It allows you to make pension contributions above the standard annual allowance (AA) in one tax year by sweeping in unused allowances from the previous three tax years. Used correctly, carry forward can enable a single contribution of up to GBP 180,000 in 2026/27 -- and every penny going in receives tax relief at your marginal rate.

What Is the Pension Annual Allowance?

The annual allowance is the maximum amount of pension savings (contributions plus employer contributions) that can receive tax relief in a single tax year. For 2026/27 it is GBP 60,000. This limit was permanently raised from GBP 40,000 to GBP 60,000 from April 2023.

If your total pension input in a year exceeds the annual allowance, the excess is subject to the annual allowance charge -- which effectively taxes away the relief, making over-contributing pointless without carry forward.

How Carry Forward Works

Carry forward allows you to use unused annual allowances from the three previous tax years. The years available for carry forward into 2026/27 are:

• 2025/26 (AA was GBP 60,000)
• 2024/25 (AA was GBP 60,000)
• 2023/24 (AA was GBP 60,000)

The maximum theoretical carry forward is GBP 60,000 x 3 = GBP 180,000 if you made zero pension contributions in all three years. Added to the current year GBP 60,000, the maximum total contribution in 2026/27 is GBP 180,000.

In practice, most people will have made some contributions in previous years. The carry forward available is whatever was unused from each year.

Condition 1: Scheme Membership

You must have been a member of a registered pension scheme in each tax year whose unused allowance you want to carry forward. Being a member of a workplace pension -- even a defined benefit scheme where you made no personal contributions and the employer made a small notional contribution -- counts.

If you were not a member of any pension scheme in a particular year, you cannot carry forward from that year.

Condition 2: Earnings Must Cover the Contribution

Your total pension contribution (your contributions plus employer contributions) in 2026/27 cannot exceed your UK earnings (employment income, self-employment profit, or other earnings) in 2026/27. This earnings cap applies to the current year contribution -- not to carry forward separately.

If you earn GBP 90,000 in 2026/27, you can only contribute GBP 90,000 in total to pensions, regardless of how much carry forward is available. You cannot use earnings from prior years.

The Order of Use

Carry forward must be used in chronological order -- older years first. So the 2023/24 unused allowance is applied before 2024/25, which is applied before 2025/26. Only after exhausting the current year GBP 60,000 allowance does carry forward kick in.

Worked Example: GBP 90,000 Contribution

Deborah is a higher-rate taxpayer who earns GBP 120,000 in 2026/27. She has the following pension contribution history:

• 2023/24: Contributed GBP 10,000 (unused allowance: GBP 50,000)
• 2024/25: Contributed GBP 15,000 (unused allowance: GBP 45,000)
• 2025/26: Contributed GBP 20,000 (unused allowance: GBP 40,000)

Total carry forward available: GBP 135,000

Deborah wants to make a one-off personal pension contribution of GBP 90,000 in 2026/27 (in addition to her employer's GBP 10,000 contribution). Total pension input: GBP 100,000.

Step 1: Current year allowance used first -- GBP 60,000 of the GBP 100,000 is covered. Step 2: GBP 40,000 remaining -- use oldest year first (2023/24: GBP 50,000 available). This covers the remaining GBP 40,000 fully.

No annual allowance charge applies. Deborah receives GBP 36,000 of higher-rate tax relief on her GBP 90,000 contribution (40% of GBP 90,000), with basic rate relief already added at source.

Tapered Annual Allowance Interaction

High earners with adjusted income above GBP 260,000 face a tapered annual allowance. For every GBP 2 of income above GBP 260,000, the AA reduces by GBP 1, down to a minimum of GBP 10,000.

For carry forward purposes, the amount carried forward from a previous year is the AA that actually applied to that individual in that year -- which may have been a reduced tapered amount. You cannot assume GBP 60,000 of carry forward per year if you were subject to tapering in prior years.

Carry forward can still be used by those with a tapered AA, but the calculation is more complex and professional advice is worthwhile.

Money Purchase Annual Allowance (MPAA)

If you have flexibly accessed your pension (taken income drawdown, an uncrystallised fund pension lump sum, or a flexible annuity), the MPAA applies to your money purchase pension input. The MPAA for 2026/27 is GBP 10,000 and carry forward cannot be used to increase the MPAA. This significantly limits the ability to catch up on pension saving after flexible access.

Defined Benefit Schemes and Pension Input

For defined benefit (final salary) schemes, pension input is measured differently -- as the opening value of accrued benefits, revalued at CPI, subtracted from the closing value, multiplied by 16. This can use up annual allowance even without any personal contributions. Defined benefit members should obtain a Pension Input Statement from their scheme before planning carry forward contributions to a money purchase scheme.

When Is Carry Forward Useful?

Carry forward is most valuable when:

• You have received a large bonus, share vesting, or other windfall in one year
• You are approaching retirement and want to maximise your pension pot
• You have just become self-employed after years in employment and can now contribute more flexibly
• You have unused allowances from years of low income or career breaks

How to Claim

Carry forward does not need to be claimed from HMRC in advance. You simply make the contribution, ensure total pension input does not exceed the available allowance (current year plus carry forward), and report accordingly through Self Assessment. Keep records of your pension contributions for the preceding three years to support any HMRC query.

Summary

Pension carry forward in 2026/27 offers a valuable opportunity for eligible individuals to supercharge their retirement savings. With a potential maximum contribution of GBP 180,000 in one year (subject to earnings), and full income tax relief at your marginal rate, carry forward can be transformative for those who have the funds to use it. Verify your unused allowances, check the membership condition for each prior year, and confirm your earnings cover the intended contribution before proceeding.
