Pension Carry Forward: Using Unused Allowance from Previous Years

Had a windfall, bonus, or simply want to make a large pension contribution? Carry forward lets you use unused annual allowance from the last three tax years to boost your pension and your tax relief.

What Is Pension Carry Forward?

Pension carry forward is a valuable rule that allows you to use any unused annual allowance from the previous three tax years to make larger pension contributions in the current year. It is one of the most effective ways to boost your pension savings while claiming generous tax relief.

The standard annual allowance for pension contributions is £60,000. If you have not used all of this in previous years, you can carry the unused portion forward and add it to your current year's allowance. In theory, this means you could contribute up to £240,000 in a single tax year (the current year's £60,000 plus three years of unused £60,000 allowances).

Important limitation: While carry forward can increase your annual allowance significantly, tax relief on contributions is still limited to 100% of your UK relevant earnings in the current tax year. If you earn £80,000, you cannot get tax relief on contributions exceeding £80,000, even if your carry forward allowance is much higher.

The Rules of Carry Forward

There are several conditions that must be met to use carry forward:

  1. You must have been a member of a registered pension scheme in each tax year you want to carry forward from. You do not need to have made contributions – simply being a member of a scheme (including a dormant one) is sufficient.
  2. You must use the current year's allowance first. You can only dip into carry forward once your current year's £60,000 allowance is fully used.
  3. Oldest year's unused allowance is used first. If carrying forward from multiple years, the earliest available year is used before more recent ones.
  4. Contributions cannot exceed your UK relevant earnings. Tax-relievable contributions are capped at 100% of your annual earnings.
  5. Employer contributions count. Both personal and employer contributions (including salary sacrifice) are included when calculating how much allowance you have used in each year.

How to Calculate Your Available Carry Forward

To work out how much carry forward you have available, you need to know your annual allowance and total pension contributions for each of the previous three tax years.

Tax YearAnnual AllowanceTotal ContributionsUnused (Carry Forward)
2023/24£60,000£15,000£45,000
2024/25£60,000£20,000£40,000
2025/26£60,000£25,000£35,000
2026/27 (current)£60,000Available: £60,000 + £120,000 = £180,000

In this example, the individual has £120,000 in unused carry forward from the three previous years, plus the current year's £60,000, giving a total available allowance of £180,000. However, they can only get tax relief on contributions up to their current year earnings.

Worked Example: Using Carry Forward

David earns £150,000 in 2026/27. He receives a £200,000 inheritance and wants to make a large pension contribution. His pension history:

  • 2023/24: £60,000 allowance, £10,000 contributed = £50,000 unused
  • 2024/25: £60,000 allowance, £10,000 contributed = £50,000 unused
  • 2025/26: £60,000 allowance, £10,000 contributed = £50,000 unused
  • 2026/27: £60,000 current year allowance

David's total available allowance is £60,000 + £150,000 = £210,000. However, his earnings are £150,000, so tax-relievable contributions are capped at £150,000. He contributes £150,000:

  • First uses £60,000 of 2026/27 allowance
  • Then £50,000 from 2023/24 carry forward
  • Then £40,000 from 2024/25 carry forward
  • Leaves £10,000 unused from 2024/25 (lost after this year) and £50,000 from 2025/26 (available next year)
Time-sensitive: Unused allowance from 2023/24 can only be carried forward to 2026/27. If not used by 5 April 2027, it is lost permanently. Review your carry forward position before the end of each tax year to avoid missing out.

Carry Forward and the Tapered Annual Allowance

If you are subject to the tapered annual allowance, carry forward still works, but the unused allowance from each year is based on your actual (tapered) allowance for that year.

For example, if your annual allowance was tapered to £20,000 in 2024/25 and you contributed £15,000, you can only carry forward £5,000 from that year – not £45,000. This significantly reduces the carry forward available to high earners.

Carry Forward and the MPAA

If you have triggered the Money Purchase Annual Allowance (MPAA) by flexibly accessing your pension, carry forward is restricted. You cannot carry forward unused MPAA (£10,000) from previous years to increase your money purchase contributions. However, if you also have defined benefit pension accrual, the carry forward rules interact differently, and specialist advice is recommended.

Who Benefits Most from Carry Forward?

Carry forward is particularly useful for:

  • Self-employed individuals with variable income who have good and bad years
  • People receiving bonuses, commissions, or windfalls who want to shelter a large sum from tax
  • Those approaching retirement who want to make a final boost to their pension pot
  • Higher and additional rate taxpayers who want to maximise their tax relief
  • Company directors who can make large employer contributions in profitable years
  • People who have recently started earning more and have unused allowance from lower-earning years

Carry Forward for Employer Contributions

Company directors and business owners can use carry forward to make large employer contributions. This is particularly attractive because employer contributions are a tax-deductible business expense, reducing Corporation Tax. A limited company can contribute up to the director's available annual allowance (including carry forward), provided HMRC considers the contribution a genuine business expense.

Practical Steps to Use Carry Forward

  1. Check your pension membership history – confirm you were a member of a registered pension scheme in each year you want to carry forward from
  2. Calculate your contributions for each year – include both personal and employer contributions, including salary sacrifice
  3. Determine the annual allowance for each year – account for any taper that applied
  4. Check your current year earnings – tax relief is limited to 100% of your UK relevant earnings
  5. Make the contribution before 5 April – contributions must be received by your pension provider before the tax year end to count
  6. Keep records – document your carry forward calculation in case HMRC queries it
End of tax year tip: If you have significant carry forward available, consider making contributions before 5 April to avoid losing the oldest year's unused allowance. See our guide on end of tax year pension contributions for more tips.

Reporting Carry Forward

There is no formal claim process for carry forward. You simply make the contribution and ensure it falls within your combined allowance. However, if your contributions in the current tax year exceed £60,000, you should report this on your Self Assessment tax return and include details of the carry forward amounts used. This demonstrates to HMRC that no annual allowance charge is due.

If you do not normally file Self Assessment, you do not need to start just to report carry forward use, unless your contributions exceed the standard £60,000 in the current year.
