Pension Tax Year-End Planning: Actions Before 5 April

The UK tax year ends on 5 April each year. Unlike some financial deadlines that can feel arbitrary, this one has real and lasting consequences for pension savers — unused annual allowance expires at the end of the tax year, carry forward entitlements have a three-year expiry, and contributions made after midnight on 5 April count in the new tax year, not the old one.

For those with higher incomes, returning expats, or anyone making large pension contributions, reviewing your position before the year-end is essential annual housekeeping.

1. Use Your Annual Allowance

The standard annual allowance (AA) for 2026/27 is £60,000. This is the maximum total pension input — encompassing your personal contributions, employer contributions, and any increase in the value of defined benefit entitlements — that can be made to registered pension schemes in the tax year and still qualify for tax relief.

Unused AA from the current year cannot be carried forward to the next year (only the three previous years can be carried forward, as described below). If you have scope to make additional contributions before 5 April and have not used your full £60,000, consider doing so — particularly if:

• You have received a bonus or unusually high earnings this year that make a larger contribution tax-efficient.
• You are a higher or additional rate taxpayer: contributions attract relief at your marginal rate (40% or 45%), and the relief must be claimed in the year the contribution is made.
• Your employer will match additional voluntary contributions before the year-end.

For employer contributions: these go through payroll and must be processed by your employer before 5 April to count in the current tax year. Speak to your HR or payroll team well in advance — there may be a February or March cut-off for processing.

For personal contributions: you can make a personal contribution to a SIPP or personal pension at any time up to 5 April. Online platforms typically process same-day contributions. Allow a couple of days' margin rather than leaving it to the last minute.

2. Carry Forward: Using Unused Allowance from Previous Years

If you have unused AA from the three preceding tax years — 2023/24, 2024/25, or 2025/26 — you can carry it forward to the current year and make a contribution exceeding the standard £60,000 limit.

Rules for carry forward:

• You must have been a member of a registered pension scheme in each year you are carrying forward from. Membership does not require contributions — being an active, deferred, or pensioner member of any UK scheme suffices.
• You must use your full current year's AA before drawing on carry forward.
• The total contribution in the carry forward year cannot exceed your relevant UK earnings for that year (unless you are using the employer contribution route, which has different rules).
• You cannot carry forward from years before 6 April 2023.

Previous AA limits: the AA rose from £40,000 to £60,000 for 2023/24 following the Spring Budget 2023 increase, and has remained £60,000 since. All three carry-forward years available for 2026/27 (2023/24, 2024/25 and 2025/26) therefore had a £60,000 standard AA. If you have made no or minimal contributions in those years, the carry forward pool could be substantial.

Claiming carry forward: it is not a formal HMRC application — you simply make the contribution and report it on your self-assessment return if required. However, record-keeping matters: document the membership years, the unused AA figures, and the calculation supporting the contribution level.

3. Check Your Tapered Annual Allowance Position

For higher earners, the annual allowance may be reduced — potentially significantly. The taper applies where:

• Your threshold income (broadly, income before pension contributions) exceeds £200,000, AND
• Your adjusted income (income including pension contributions) exceeds £260,000.

Where both thresholds are breached, the AA is reduced by £1 for every £2 of adjusted income above £260,000. The minimum tapered AA is £10,000 — reached when adjusted income exceeds £360,000.

Before 5 April, you should review:

• Whether your total remuneration including bonuses, dividends, rental income, and other sources will push you above these thresholds.
• Whether there are legitimate steps to manage adjusted income — for example, deferring a bonus into the next tax year, or maximising salary sacrifice (which reduces relevant earnings and therefore adjusted income).
• Whether carry forward from previous years — when you may have had a higher AA — is available to offset any excess pension input.

Getting this calculation wrong in either direction is costly: contributing too little means wasted tax relief, while contributing too much means an annual allowance charge equal to the excess pension input at your marginal rate.

4. The £2,880 Non-Earner Contribution

One of the more underused provisions in UK pensions is the ability to contribute to a pension even with no relevant UK earnings. The rules permit:

• Any UK resident, regardless of earnings, to contribute up to £2,880 net per year to a personal pension.
• The pension provider claims basic rate tax relief, grossing the contribution up to £3,600.

This applies to:

• Non-working spouses or partners
• Children (including adult children with no income)
• Retirees who have ceased working but are below age 75
• Those in receipt of only passive income (dividends, rental, savings interest) that does not count as relevant earnings

For a non-working spouse, this represents a free £720 per year from the government (basic rate relief on £2,880), compounding within the pension wrapper over years or decades. Starting a pension for a young adult child at minimal cost can build a meaningful retirement pot over time.

The contribution must be made by 5 April to count in that tax year.

5. The Year of Return to the UK

For individuals who have been non-UK resident and are returning to the UK, the tax year of return presents a specific planning opportunity.

If you become UK resident at any point in the tax year, you are treated as UK resident for the full year for pension contribution purposes — you can contribute up to the full £60,000 annual allowance for that year, even if you were abroad for the majority of it.

Additionally, carry forward from the three preceding years may be available. Non-UK residents who were not making pension contributions in those years will typically have large amounts of unused AA sitting in the carry forward pool — potentially £180,000 (three years at the current £60,000 AA).

If you are returning to the UK with high income and want to make a substantial pension contribution in the year of return, this combination of the full current-year AA plus generous carry forward can enable a very large contribution — potentially £180,000 or more — all attracting tax relief.

Planning this correctly requires:

• Confirming the statutory residence test position for the return year.
• Establishing whether you had pension scheme membership in the carry forward years.
• Verifying that relevant UK earnings in the return year are sufficient to support the contribution level (personal contributions are limited to 100% of UK earnings, though employer contributions operate differently).

6. The Annual Allowance Trap for Returning Expats

A related but distinct issue affects expats who are carrying unused AA from years when they were non-resident. The carry forward rules require only pension scheme membership — not UK residency — in the carry forward years. This means:

• An expat who maintained a SIPP or deferred occupational pension during years abroad has carried forward AA from those years.
• On returning to the UK with high income, they can potentially access substantial carry forward capacity.

The trap arises in the opposite direction: if you have been making contributions to a foreign pension scheme that HMRC treats as a registered scheme (or that counts against the UK AA), those contributions may have used AA in those years — reducing the carry forward available.

Overseas pension contributions are complex. If your employer was contributing to a local pension scheme abroad, the interaction with UK carry forward requires professional advice before you make assumptions about available capacity.

Practical Year-End Timeline

For most individuals, a sensible year-end pension planning process involves:

By 1 February: review total pension inputs for the year to date — your own contributions plus employer contributions plus any DB accrual.

By 1 March: calculate remaining AA headroom. Consider whether carry forward is available and whether additional contributions make sense.

By 15 March: instruct any employer contributions through payroll. Many payroll deadlines for pension processing fall in early-to-mid March.

By 31 March: make any final personal SIPP contributions. Leaves a buffer against processing delays.

5 April (midnight): final deadline. Contributions after this date count in the following tax year.
