Pension Carry Forward 2025/26
Use Unused Allowance From 3 Years

You have had an exceptional year, a big bonus, a profitable trading period, the sale of a business, and you want to shelter as much as possible in a pension. The annual allowance caps you at GBP 60,000. But pension carry forward can let you pay in far more in a single year by reaching back and using allowance you did not use in the previous three tax years. Used well, it is one of the most powerful tax-planning tools available to higher earners and the self-employed with lumpy income.

Carry forward only makes sense once you understand the standard pension annual allowance of GBP 60,000, so read that first if the basics are unfamiliar. This page covers how to stack additional allowance on top, and the pension planner calculator helps you test how much you could contribute given your own history and earnings.

The Three Conditions That Make Carry Forward Work

Carry forward is automatic in the sense that there is no form to file, but three conditions must be satisfied:

1. You have used the current year's full allowance. You cannot dip into prior years until you have used the whole GBP 60,000 (or your tapered allowance) for 2025/26.
2. You were a pension scheme member in the relevant prior years. Membership of a registered UK scheme is required, even if you paid in nothing that year. No membership, no carry forward from that year.
3. You have enough earnings this year. Tax relief on personal contributions is still capped at 100 percent of your relevant UK earnings in the year you contribute. Carry forward raises the allowance ceiling but not the earnings cap.

The Order of Use

The sequence matters, because it determines how much you can carry forward and which year's allowance expires first. You always use:

1. The current year (2025/26) allowance in full, then
2. The oldest available year (2022/23), then
3. The next year (2023/24), then
4. The most recent prior year (2024/25).

Using the oldest first is deliberate: allowance older than three years is lost forever, so HMRC's rules ensure you draw on the about-to-expire allowance before the fresher amounts.

Worked Example: Stacking Four Years

Suppose your pension input over the recent years looked like this. Note that 2022/23 had the old GBP 40,000 allowance before it rose to GBP 60,000 in April 2023.

The total available to you in 2025/26 is the current GBP 60,000 plus GBP 25,000 + GBP 40,000 + GBP 30,000 carried forward, a maximum of GBP 155,000. But, crucially, you can only get personal tax relief on this if your relevant UK earnings this year are at least GBP 155,000. If you earn GBP 90,000, your personal contribution is capped at GBP 90,000 by the earnings rule, even though GBP 155,000 of allowance is technically available.

If you are a sole trader with a one-off profitable year

You are self-employed and most years make GBP 40,000, paying GBP 5,000 a year into your pension. This year you sold a major contract and your taxable profit is GBP 140,000. You have three prior years each with around GBP 55,000 of unused allowance (using the GBP 60,000 limit minus your GBP 5,000 contributions), so roughly GBP 165,000 of carry forward plus this year's GBP 60,000.

Your earnings this year are GBP 140,000, which becomes the binding limit. You could pay in up to GBP 140,000 and get full relief, comfortably within your available allowance. At higher and additional rates, the relief on that contribution is substantial. The pension planner will show the exact relief and the effect on your tax bill.

Carry Forward and the Earnings Cap: The Most Common Mistake

The error people make again and again is assuming carry forward lets them ignore their earnings. It does not. There are two separate limits and you must satisfy both:

• The allowance limit (current GBP 60,000 plus carry forward) governs when an annual allowance charge applies.
• The earnings limit (100 percent of relevant UK earnings, or GBP 3,600) governs how much personal tax relief you can get.

Employer contributions are not restricted by your earnings, only by the allowance. So a company director can sometimes use a large employer contribution plus carry forward to pay in well above their salary, a route not open to personal contributions.

How the Taper Interacts With Carry Forward

If you were a high earner subject to the tapered annual allowance in any of the prior three years, the amount you carry forward from that year is the tapered allowance you actually had, not the full GBP 60,000. So a year where your allowance was tapered to GBP 15,000 and you contributed GBP 5,000 gives you only GBP 10,000 of carry forward from that year. Tapered earners therefore need to compute each prior year's actual allowance carefully before relying on carry forward.

Records You Should Keep

There is no claim to submit for carry forward, but you must be able to prove your figures if HMRC asks. Keep, for each of the three prior years:

• Your annual allowance for that year (standard, tapered, or the MPAA-limited GBP 10,000 if relevant).
• Your total pension input for that year, from all sources.
• Evidence that you were a member of a registered scheme.

Good digital records make this painless. The same discipline that Making Tax Digital encourages from April 2026, capturing financial data as it happens rather than reconstructing it later, is exactly what makes carry forward calculations reliable when you need them.
