Carry Forward of Unused Pension Allowance: Using Three Prior Years to Boost Your Contributions

If you have not maxed out your pension allowance in the last three years, you can roll forward the unused amount. For business owners with profit windfalls, this is a powerful tax planning lever.

The £60,000 annual pension allowance feels like a hard ceiling — but it is not. UK pension rules allow you to carry forward unused allowance from the previous three tax years, potentially permitting a contribution well in excess of £60,000 in a single year. For business owners with a profit windfall, a sale of a business, or a delayed bonus, carry forward is the single most powerful contribution planning tool in the regime.

How carry forward works

For any tax year, you can use the allowance from that year plus any unused allowance from the previous three years. The allowance for each year was £40,000 up to 2022-23 and £60,000 from 2023-24 onwards. So in 2025-26 you could potentially contribute:

  • £60,000 — current year (2025-26)
  • + up to £60,000 — unused from 2024-25
  • + up to £60,000 — unused from 2023-24
  • + up to £40,000 — unused from 2022-23
  • = up to £220,000 in a single year

The conditions you must meet

Carry forward is not free money — there are eligibility rules. You must:

  • Have been a member of a registered pension scheme in each year you want to carry forward from, even if you made no contributions in that year.
  • Use the current year's allowance first. You only access carry forward after exhausting the current £60,000.
  • Use the oldest year's allowance first when accessing carry forward. So 2022-23 must be used before 2023-24, and so on.
  • Have relevant UK earnings for the full personal contribution. Personal contributions are still capped at 100% of earnings — only employer contributions can exceed earned income.

The employer contribution advantage

For an owner-managed company, employer contributions are not restricted by the director's salary level. A director taking a £12,000 salary can still receive a £100,000+ employer pension contribution if carry forward is available — provided it passes the "wholly and exclusively" test and the company has the profits to fund it.

For example, a software founder selling part of the business who has a bumper profit year of £300,000 in 2025-26 might decide to push £150,000 of that profit into their SIPP as an employer contribution, drawing on the current year's allowance plus carry forward from the previous two years. The contribution is deductible against Corporation Tax at 26.5% in the marginal band, the personal tax position is unaffected, and the wealth sits in a tax-protected wrapper. The savings against extracting the same amount as a dividend can run into tens of thousands.

Tapering interaction

Carry forward uses the tapered allowance for each prior year — not the headline figure. So if your adjusted income in 2024-25 was £300,000, your taper-reduced allowance for that year might be £40,000, and only the unused portion of that £40,000 can be carried forward. Modelling this correctly takes care.

Common mistakes

The most frequent error we see is contributing the full £200,000 carry forward amount only to discover later that the director was not a scheme member in one of the qualifying years — making that year's allowance unavailable. The second is forgetting that personal contributions cannot exceed earnings, which catches directors who pay themselves a £12,000 salary and try to make a £60,000 personal contribution.

How PushDigits models carry forward

For every owner-manager client, our tax planning reviews show a 4-year contribution history alongside available carry forward, the tapered position, and the optimal contribution before each year-end. We coordinate the company-side accounting through our business advisory team so the deduction lands in the right accounting period.

If you have a profit windfall, a business sale, or an underused pension allowance from the last three years, book a call with PushDigits or get in touch through our contact page. The window for any given tax year closes at midnight on 5 April — and once it closes, the oldest year drops off the carry-forward stack forever.
