UK Pension Carry Forward Explained: Using Unused Annual Allowance
What carry forward actually is
The annual allowance is the maximum you can pay into a UK registered pension scheme each tax year and still get full income tax relief. For 2026/27 it’s £60,000 (or 100% of your earnings, whichever is lower). Anything contributed above the annual allowance triggers the annual allowance charge — a tax bill clawing back the relief on the excess.
Carry forward is the rule that lets you use unused annual allowance from the previous three tax years to push this year’s total contribution above £60,000 without triggering the charge. Used at maximum it can let you contribute up to £200,000 in a single year (current year + three years carried forward, depending on past allowance levels).
It exists because pension contribution patterns are lumpy in real life — bonus years, business sales, late-career catch-up, inheritances — and a strict annual cap would penalise that lumpiness. Carry forward smooths it out.
The eligibility rules
Three conditions must be met to carry forward unused allowance from a previous tax year:
- You must have been a member of a UK registered pension scheme in that year. Membership is enough — you don’t need to have actually contributed. A workplace scheme you joined and never paid into still counts, as does a SIPP you opened but didn’t fund. If you weren’t a member at all (no pension scheme of any kind), there’s no allowance to carry forward from that year.
- You must have used up the current year’s full annual allowance first. Carry forward is layered: you use this year’s £60,000 first, then dip into prior years in chronological order (oldest unused first).
- The contribution still has to be within 100% of your relevant UK earnings for the current tax year. Carry forward doesn’t override the earnings cap. If you earn £50,000 this year, you can’t contribute £100,000 even if you have £200,000 of cumulative unused allowance — you’re capped at your earnings.
The “oldest first” rule matters. Unused allowance expires after three years, so the oldest year drops off first. Using it first preserves the more recently accrued allowance for next year.
The current and historical annual allowances
To work out how much you can carry forward, you need to know the annual allowance for each of the previous three tax years:
| Tax year | Annual allowance | Notes |
|---|---|---|
| 2026/27 | £60,000 | Current year |
| 2025/26 | £60,000 | |
| 2024/25 | £60,000 | |
| 2023/24 | £60,000 | First year at £60k (raised from £40k in April 2023) |
| 2022/23 | £40,000 | (No longer carry-forwardable in 2026/27) |
A taxpayer in 2026/27 with no prior contributions in the carry-forward window has the maximum: £60,000 + £60,000 + £60,000 + £60,000 = £240,000 of headroom. In practice it’s almost always less than this because most pension savers have made some contributions in those years.
How the calculation works — worked example
Take an investment banker, Priya, who earns £180,000 in 2026/27 and has the following contribution history:
| Tax year | Allowance | Used | Unused (available to carry forward) |
|---|---|---|---|
| 2023/24 | £60,000 | £20,000 | £40,000 |
| 2024/25 | £60,000 | £30,000 | £30,000 |
| 2025/26 | £60,000 | £40,000 | £20,000 |
| 2026/27 | £60,000 | (planning…) | (this year) |
Her maximum gross contribution in 2026/27 is:
- 2026/27 current year allowance: £60,000
- Plus 2023/24 unused (oldest first): £40,000
- Plus 2024/25 unused: £30,000
- Plus 2025/26 unused: £20,000
- Total available: £150,000
She’s well within her £180,000 earnings, so the full £150,000 is on the table. If she contributes the lot at 40% marginal rate, the tax relief is £60,000 — making the net cost £90,000 for £150,000 of pension contribution. Use the pension contribution calculator UK to model your own numbers including the relief.
The tapered annual allowance for high earners
This is where carry forward gets harder. If your adjusted income (broadly: total taxable income plus employer pension contributions) exceeds £260,000 in a tax year, your annual allowance for that year tapers down by £1 for every £2 of adjusted income above the threshold, to a minimum of £10,000 at adjusted income of £360,000+.
For carry forward purposes you use the tapered allowance from each of the previous three years — not the headline £60,000. So a high earner whose adjusted income was £320,000 in 2024/25 had an annual allowance for that year of only £30,000, and any unused portion of that £30,000 is what’s carry-forwardable.
A separate “threshold income” test of £200,000 acts as a gate — if your threshold income (broadly: taxable income excluding employer contributions and with personal pension contributions added back) is below £200k, the taper never bites no matter what your adjusted income is. This matters for people whose only large income items are bonuses or RSUs in a single year.
The taper rules are intricate. The HMRC online tool is the most reliable way to confirm your tapered figure for a past year if it’s borderline. The pension contribution calculator linked above assumes the standard £60,000 — if you’re inside the taper zone, adjust the input accordingly.
The annual allowance charge
If you contribute above the available allowance (current year plus carry forward), the excess is added to your taxable income for the year and taxed at your marginal rate. This is the annual allowance charge — effectively a clawback of the tax relief on the over-contribution.
For a 40% taxpayer, an excess of £10,000 generates a £4,000 charge. For a 45% additional-rate taxpayer the charge is £4,500.
Two practical paths to settle it:
- Pay it through self-assessment. Declare the excess on your tax return; HMRC adds the charge to your tax bill. The self-assessment calculator handles this alongside the rest of your liability.
- Scheme Pays. If the charge exceeds £2,000 and your annual allowance excess in the scheme is over £40,000, you can ask your pension scheme to pay the charge from your pension pot. This avoids an immediate cash outlay but permanently reduces your retirement fund.
The trick to avoid the charge is to model the contribution before making it — particularly in tax years when bonuses or large employer contributions are landing.
Interaction with the money purchase annual allowance (MPAA)
A separate, more restrictive rule: if you’ve already started flexibly drawing from a defined contribution pension (e.g. an UFPLS withdrawal, or flexi-access drawdown income beyond the tax-free lump sum), you trigger the money purchase annual allowance of £10,000 for future contributions to any defined contribution pension.
The MPAA replaces the normal £60,000 annual allowance for DC contributions, and crucially you cannot carry forward into the MPAA. So someone who started drawdown at age 56 and continues working with significant earnings is restricted to £10,000/year in DC contributions thereafter, with no carry-forward relief available.
This is one of the most under-appreciated traps in UK pension planning. If you’re considering taking any flexible payment from a DC pension while still working, check whether the trigger will lock you out of meaningful future contributions.
Frequently asked questions
Do I need to formally elect to use carry forward? No. There’s no separate election or form. As long as you contribute within the available headroom (current year + unused prior three years), HMRC treats it as carry forward automatically. Just keep records of your contributions and allowances for each year in case you’re queried.
Can I carry forward employer contributions? Yes — the annual allowance applies to combined personal and employer contributions to all your pensions. If your employer contributes £30,000 in a year, that uses £30,000 of the allowance regardless of who paid it.
What if I only joined a pension scheme last year? Then you can only carry forward unused allowance from the year you joined onwards. You cannot create retrospective scheme membership for prior years.
Does carry forward affect the lifetime allowance? The lifetime allowance was abolished in April 2024 and replaced with two new lump sum allowances. Carry forward affects contributions in, not benefits out, so it operates independently of the lump sum rules. However, very large contributions still need consideration alongside the lump sum allowance and lifetime allowance charge transition rules if you have protections in place.
Is the £60,000 allowance going to change? No change was announced in the most recent Budget. The £60,000 figure has been stable since April 2023 (raised from £40,000) and there’s no current legislative timeline to alter it. The taper thresholds (£200k / £260k) are similarly stable. Always sense-check against the latest HMRC PTM page before making a large contribution decision.
What if my income is below the annual allowance? You can only get tax relief on pension contributions up to 100% of your relevant UK earnings in the tax year (or £3,600 gross if you have no earnings — the basic minimum). Carry forward doesn’t extend this — even with £200k of cumulative headroom, someone earning £30k can only contribute £30k that year and get full relief.
