Pension annual allowance carry forward allows eligible UK pension scheme members to use unused annual allowance from the previous three tax years. It can help prevent an annual allowance tax charge when pension savings exceed the current year's allowance. But before relying on it, you need to check pension input amounts, scheme membership, prior carry-forward usage and any reduced allowances. This practical records checklist explains exactly what to gather, how to calculate your position and which mistakes to avoid.
Tax-year reference: This guide uses the 2026/27 UK tax year, from 6 April 2026 to 5 April 2027. The standard annual allowance is £60,000, although individual circumstances can reduce it.
Quick Checklist: What Records Do You Need?
Before making a large pension contribution, assemble a four-year record covering the current tax year and the three preceding years.
Pension carry-forward records checklist
- ☐ Names of all pension schemes and providers
- ☐ Dates of pension scheme membership
- ☐ Annual pension input amounts for each scheme
- ☐ Employee and personal pension contributions
- ☐ Employer contributions, including salary-sacrifice contributions
- ☐ Defined benefit pension input statements, if applicable
- ☐ Annual allowance applicable to each tax year
- ☐ Adjusted income and threshold income calculations, where relevant
- ☐ Records of flexible pension access and MPAA notices
- ☐ Previous carry-forward calculations and usage
- ☐ Pension savings statements and relevant tax-return records
The objective is to establish how much unused allowance genuinely remains, not simply how much you contributed in previous years.
1. How Pension Annual Allowance Carry Forward Works
The pension annual allowance measures pension savings for tax purposes. In a defined contribution scheme, pension input generally includes gross personal contributions and employer contributions. In a defined benefit scheme, the calculation instead uses a prescribed measure of growth in pension benefits.
Under HMRC's official carry-forward guidance, eligible unused annual allowance from the three preceding tax years may be used when pension input exceeds the current year's available allowance.
Which years count in 2026/27?
| Tax year | Standard allowance | Role |
|---|---|---|
| 2023/24 | £60,000 | Oldest eligible year |
| 2024/25 | £60,000 | Second eligible year |
| 2025/26 | £60,000 | Most recent previous year |
| 2026/27 | £60,000 | Current-year allowance |
These are standard figures rather than guaranteed personal allowances. High-income tapering, flexible pension access and other special rules may affect the amount available. HMRC publishes the relevant figures in its pension scheme rates and allowances.
Use the oldest available allowance first
Carry forward follows a prescribed order:
- Use the current tax year's available allowance first.
- Use remaining unused allowance from the earliest eligible preceding tax year.
- Move to the next preceding year only when necessary.
- Continue until the pension input is covered or all eligible allowance is exhausted.
For 2026/27, the order is 2023/24, then 2024/25, then 2025/26.
Unused 2023/24 allowance cannot be carried forward into 2027/28. However, you must also check whether any of that allowance was already consumed in an intervening year.
2. Collect the Right Pension Statements
Defined contribution pensions
For workplace defined contribution pensions, personal pensions and self-invested personal pensions (SIPPs), obtain contribution histories showing the gross amounts allocated to each tax year.
Include:
- Personal contributions before accounting for any relief-at-source tax uplift.
- Employer pension contributions.
- Employer contributions made through salary sacrifice.
- Additional voluntary contributions.
- Contributions made by another party on your behalf.
For example, a £8,000 personal payment into a typical relief-at-source pension may become a £10,000 gross contribution once the provider adds £2,000 of basic-rate tax relief. The pension input calculation generally uses the £10,000 gross amount.
Do not confuse pension transfers with new contributions. A qualifying transfer between registered pension schemes is generally not itself a new contribution for annual allowance purposes, although special situations may need review.
Defined benefit pensions
Defined benefit schemes require different records. The pension input amount is based on the calculated increase in the value of accrued benefits, taking account of the applicable statutory rules.
Your employee contributions alone are not an adequate measure.
Ask the scheme administrator for each year's pension input amount and any available pension savings statement. This is particularly important if you received a substantial pay rise, promotion or change in accrued benefits.
Previous employers and multiple schemes
If you changed jobs during the review period, obtain records from every relevant workplace scheme.
Do not assume that a statement from your current pension provider includes contributions made to a previous employer's scheme.
Also check any personal pension or SIPP receiving separate contributions, even where those payments are relatively small.
3. Build a Four-Year Pension Records Worksheet
A useful worksheet should record the applicable annual allowance, total pension input, previous carry-forward usage and remaining available balances.
| Record | 23/24 | 24/25 | 25/26 | 26/27 |
|---|---|---|---|---|
| Applicable allowance | £___ | £___ | £___ | £___ |
| Pension input | £___ | £___ | £___ | £___ |
| Unused before adjustments | £___ | £___ | £___ | £___ |
| Previously used | £___ | £___ | £___ | N/A |
| Available balance | £___ | £___ | £___ | N/A |
Use the applicable annual allowance after any relevant tapering or special adjustments. Record the combined pension input across all relevant arrangements.
If you used carry forward in a previous tax year, reconstruct how that earlier year's pension input was covered, including the oldest-first ordering. Do not deduct an estimated amount from a previous-year balance without reconciling the underlying calculation.
Where the money purchase annual allowance applies, separate calculations may be required rather than a single combined worksheet.
4. Worked Example: Calculating Carry Forward for 2026/27
Consider an illustrative saver who was a member of a registered pension scheme throughout the relevant period.
Assume the saver is not subject to the tapered annual allowance or money purchase annual allowance, and no unused allowance has been consumed by carry forward in earlier tax years.
| Year | Allowance | Input | Unused |
|---|---|---|---|
| 2023/24 | £60,000 | £25,000 | £35,000 |
| 2024/25 | £60,000 | £40,000 | £20,000 |
| 2025/26 | £60,000 | £50,000 | £10,000 |
The potentially available carry forward is:
£35,000 + £20,000 + £10,000 = £65,000.
Adding the standard 2026/27 annual allowance gives:
£60,000 + £65,000 = £125,000.
Now assume total pension input for 2026/27 is £90,000.
- The first £60,000 is covered by the current-year allowance.
- The remaining £30,000 requires carry forward.
- The £30,000 is drawn from the £35,000 unused balance for 2023/24.
- The remaining £5,000 from 2023/24 is not needed for this calculation.
- The balances from 2024/25 and 2025/26 remain unused.
Under these assumptions, the saver has enough annual allowance to cover the £90,000 pension input, with no annual allowance tax charge arising from it.
However, the remaining £5,000 from 2023/24 expires for carry-forward purposes after 2026/27.
Why the worksheet matters: A headline unused allowance of £65,000 does not reveal when individual balances expire. The year-by-year record shows which allowance is used and which remains available in future tax years.
5. Check Eligibility and Special Allowance Rules
Pension scheme membership
You must have been a member of a UK registered pension scheme, or a qualifying overseas pension scheme, during the previous tax year from which unused allowance is being carried forward.
Membership may exist even where no new contributions were paid during that year. Keep joining records, annual statements or written confirmation from the scheme.
Personal contribution tax relief
Annual allowance carry forward and personal pension contribution tax relief are separate tests.
Carry forward does not generally increase the amount of personal contributions eligible for tax relief based on your relevant UK earnings.
For example, an eligible person with £30,000 of relevant UK earnings cannot normally obtain tax relief on £100,000 of personal pension contributions merely because they have sufficient annual allowance carry forward.
Employer contributions have different tax-relief rules. Check the UK government's pension tax relief guidance before making unusually large contributions.
Tapered annual allowance
The tapered annual allowance can reduce the amount available to higher-income individuals.
For 2026/27, tapering can apply where threshold income exceeds £200,000 and adjusted income exceeds £260,000.
The standard £60,000 allowance is reduced by £1 for every £2 of adjusted income above £260,000, subject to a minimum of £10,000.
As an illustrative example, adjusted income of £300,000, with the threshold income condition also satisfied, produces a reduction of £20,000:
(£300,000 - £260,000) / 2 = £20,000.
The resulting tapered allowance is £40,000 before considering eligible carry forward.
For more complex income calculations, consult HMRC's tapered annual allowance guidance.
Money purchase annual allowance
The money purchase annual allowance (MPAA) can apply after certain types of flexible access to pension benefits.
For 2026/27, the MPAA is £10,000. Unused annual allowance cannot be carried forward to increase this £10,000 limit.
Unused allowance may still be relevant to certain other pension savings under the alternative annual allowance rules.
The interaction can be complex because HMRC requires specific comparisons of the potential annual allowance charges. Follow its guidance for people who have flexibly accessed their pensions.
Retain the date and nature of any relevant pension withdrawals, together with notifications from the provider.
6. Common Carry-Forward Records Mistakes
Mistake 1: Using calendar-year figures
The UK tax year runs from 6 April to 5 April. A contribution in March and one in April may belong to different tax years.
Use provider-confirmed contribution dates, especially around the tax-year boundary.
Mistake 2: Excluding employer contributions
Employer funding generally counts towards the pension input amount for a defined contribution arrangement.
Relying only on employee payroll deductions can create a misleading unused allowance figure.
Mistake 3: Treating investment growth as a contribution
Investment performance does not itself constitute new pension contributions in a defined contribution arrangement.
For instance, a pension fund rising from £100,000 to £120,000 does not mean the annual allowance calculation automatically includes £20,000 of pension input. The figure must be determined from relevant contributions rather than investment returns.
Defined benefit arrangements have their own pension input calculation and must not be treated in the same way.
Mistake 4: Forgetting earlier carry-forward usage
An unused balance calculated for a previous tax year may already have been used to cover pension input in a later year.
Always reconcile intervening tax years before counting historical unused allowance again.
Mistake 5: Assuming unused allowance lasts indefinitely
Carry forward is limited to the three preceding tax years. Unused allowance from a year eventually falls outside the permitted window.
Keep expiry information beside each annual balance.
Mistake 6: Confusing available allowance with tax relief
The annual allowance determines whether pension savings may produce an annual allowance charge. Personal contribution tax relief depends on additional rules, including relevant UK earnings and eligibility.
A contribution can fit within available annual allowance without automatically qualifying for the personal tax relief a saver expects.
7. What If Your Records Are Missing?
Missing pension statements do not necessarily mean that you cannot reconstruct your carry-forward position.
Use the following recovery process.
- Contact current providers: Request tax-year pension input details, not simply current pension valuations.
- Contact former employers: Ask which pension scheme operated during each relevant period.
- Request defined benefit figures: Obtain annual pension input amounts from the scheme administrator.
- Check payslips: Use payroll deductions as supporting information, remembering that they may not show complete pension input.
- Review previous tax records: Look for annual allowance charges, relevant declarations and earlier calculations.
- Reconcile provider data: Check discrepancies before treating the carry-forward amount as confirmed.
If an old scheme cannot readily be identified, the government's Pension Tracing Service may help locate scheme contact details. It does not calculate your carry-forward allowance or tell you the current value of a pension.
8. Do You Need to Report Carry Forward to HMRC?
Eligible unused annual allowance can be carried forward automatically. Normally, you do not submit a separate carry-forward claim simply to use it.
If enough unused annual allowance is available to cover the current year's pension savings, you generally do not need to report carry forward on a tax return solely for that reason.
However, if an annual allowance tax charge arises, the relevant amount generally must be declared through Self Assessment. Special rules may also apply to payment through a pension scheme.
HMRC explains the underlying calculation and automatic treatment in its manual on calculating unused annual allowance.
Retain your supporting calculations even where no charge is payable. A clear audit trail is particularly valuable if pension providers later correct a reported pension input amount.
9. Should You Make a Larger Contribution Now?
Carry-forward capacity may make an additional pension contribution possible without an annual allowance tax charge, but it does not automatically make that contribution financially appropriate.
Consider the following decision factors:
| Question | Why it matters |
|---|---|
| Is carry forward confirmed? | Prevents contributions based on overstated available allowance. |
| Is personal tax relief available? | Available annual allowance and tax-relievable personal contributions are not identical. |
| Can you afford to lock away the money? | Pensions generally restrict access until the applicable minimum pension age, subject to exceptions. |
| Have employer contributions been included? | They may materially reduce available annual allowance. |
| Are older balances approaching expiry? | Unused allowance from the oldest year may soon fall outside the carry-forward window. |
| Are special rules relevant? | Tapering, MPAA or defined benefit input calculations may change the outcome. |
A larger pension contribution should be evaluated alongside emergency savings, near-term spending requirements, investment risk, pension charges and expected tax treatment when benefits are eventually withdrawn.
10. Frequently Asked Questions
Can I carry forward unused annual allowance if I made no contributions in a previous year?
Potentially, yes. You generally need qualifying pension scheme membership during the relevant tax year, but actual contributions are not necessarily required. Check the membership conditions before counting unused allowance.
Can I carry forward unused allowance from four years ago?
No. The standard carry-forward window covers only the three preceding tax years. For 2026/27, the oldest eligible year is 2023/24.
Does carry forward work across different pension providers?
Yes. Annual allowance is assessed across relevant pension arrangements. You do not necessarily have to contribute to the same pension scheme from which the unused allowance calculation originated.
However, your records must account for pension input across all relevant schemes.
Can I use carry forward after taking pension benefits?
It depends on the benefits accessed and whether the MPAA was triggered. Carry forward cannot increase the MPAA itself, although it may still apply to certain other pension savings.
Is HMRC approval required before using carry forward?
No separate approval is normally needed. The rules operate automatically when their conditions are satisfied. You remain responsible for accurate calculations and any required tax reporting.
Final Checklist Before Making a Contribution
Before committing to a pension contribution that relies on carry forward, confirm the following:
- ☐ I have identified all relevant pension schemes.
- ☐ I have verified pension input amounts for each tax year.
- ☐ I have included employer contributions.
- ☐ I have checked qualifying scheme membership.
- ☐ I have applied any tapered annual allowance or MPAA rules.
- ☐ I have reconciled previous carry-forward usage.
- ☐ I have applied the oldest-first ordering rule.
- ☐ I have checked the separate personal contribution tax-relief limits.
- ☐ I have confirmed the contribution will fall in the intended tax year.
- ☐ I have saved the statements, worksheet and supporting calculations.
Bottom line: Pension annual allowance carry forward can provide valuable flexibility, particularly where pension funding varies between years. Its usefulness depends on accurate records and correctly applying the allowance rules.
Your next step: Create folders for 2023/24, 2024/25, 2025/26 and 2026/27. Obtain each relevant pension input figure, complete the worksheet and reconcile the balances before deciding how much additional pension funding is appropriate.
