Pension Input Periods and the Annual Allowance: What Expats Must Know

The annual allowance is the maximum amount that can be contributed to UK pension schemes in a given tax year without triggering a tax charge. As of 2026, the standard annual allowance stands at £60,000. But knowing the limit is only part of the picture. Understanding when contributions count towards that limit — which depends on the concept of the pension input period — is equally important, and for UK expats making contributions across multiple schemes or jurisdictions, the rules become notably more complicated.

This guide explains pension input periods, how they interact with the annual allowance, and the specific issues that arise for internationally mobile individuals.

This is a specialist area of pension tax legislation. Nothing in this guide constitutes personalised advice. Rules change, and the interaction between UK domestic law and international employment arrangements is complex. Always consult a regulated pensions specialist and tax adviser before making contribution decisions. Pension values can fall as well as rise.

What Is a Pension Input Period?

A pension input period (PIP) is the period over which pension savings are measured for annual allowance purposes. The pension input amount — the total growth or contributions counted against the allowance — is calculated by reference to the PIP that ends in a given tax year.

Since 6 April 2016, all pension input periods align with the UK tax year: 6 April to 5 April. This alignment was introduced as a simplification measure; before April 2016, PIPs could end on any date (often the scheme anniversary date), which made annual allowance calculations considerably more complex.

For anyone who had PIPs ending before April 2016 and carried unused allowances forward from that period, the transition rules applied. For anyone starting pension contributions now or in recent years, all PIPs run 6 April to 5 April.

How the Annual Allowance Is Calculated

Defined contribution (money purchase) schemes

For a defined contribution scheme — including a SIPP — the pension input amount is simply the total contributions paid into the scheme during the PIP. This includes:

• Your own contributions.
• Employer contributions.
• Any contributions made by a third party on your behalf.
• The grossed-up value of contributions made under salary sacrifice arrangements.

Note that investment growth within the scheme does not count towards the annual allowance. Only contributions.

Defined benefit schemes

For a defined benefit (DB) scheme, the pension input amount is calculated differently — it is the increase in the capital value of the accrued benefit over the PIP, using a multiplier of 16 applied to the annual pension increase:

Pension input amount = (closing accrued pension × 16) − (opening accrued pension × CPI uprating factor × 16)

In practice, the scheme administrator calculates this and is required to provide you with a pension savings statement if your pension input amount in that scheme exceeds the standard annual allowance (£60,000 for 2026/27). For expats with deferred DB benefits in a former employer's scheme, the PIP still runs and the input amount is still calculated each year, even if you are making no active contributions — though with deferred benefits it is typically small unless the scheme revaluation is high.

The Standard Annual Allowance in 2026

As of the 2026/27 tax year, the standard annual allowance is £60,000. This is the maximum combined pension input across all schemes before a tax charge applies. The excess above the allowance is added to your income and taxed at your marginal rate.

Tapered annual allowance

High earners face a reduced, tapered annual allowance. The taper applies where:

• Threshold income exceeds £200,000 (broadly, all income excluding pension contributions).
• Adjusted income exceeds £260,000 (threshold income plus employer pension contributions).

For every £2 of adjusted income above £260,000, the annual allowance reduces by £1, down to a minimum of £10,000.

For expats, this is particularly important where overseas employment income, rental income, and investment income together push adjusted income above the thresholds. Non-UK employment income is included in the adjusted income calculation for UK residents, and may also be considered where the individual retains UK pension contributions linked to UK-relevant earnings.

Expat-Specific Complications

1. What counts as UK-relevant earnings?

To receive tax relief on personal pension contributions in the UK, you need UK-relevant earnings in the same tax year. Relevant UK earnings broadly means:

• UK employment income.
• UK self-employment income.
• UK furnished holiday letting income (in some circumstances).

Income from overseas employment is not UK-relevant earnings for contribution relief purposes, even if you are UK tax resident. This is a critical point for expats: if you are living abroad and your only earnings are from an overseas employer, you cannot make personal pension contributions to a UK scheme and claim UK tax relief — except under the five-year rule (see below).

The annual allowance still technically applies to any contributions made, but you cannot claim relief on contributions exceeding your UK-relevant earnings.

2. The five-year rule for non-residents

There is a specific exception: individuals who have been UK tax resident at some point in the previous five tax years may still be able to make personal contributions and receive basic rate tax relief on up to £3,600 per year (the gross amount), regardless of earnings. This is sometimes called the "non-resident relief rule" and applies to those who have left the UK but wish to maintain some pension contributions.

Contributions above £3,600 gross per year require UK-relevant earnings. Employer contributions have different rules.

3. Employer contributions from overseas employers

Some expat employees receive employer contributions into UK pension schemes from overseas employers. Whether these contributions qualify for UK tax relief and how they are treated for annual allowance purposes depends on:

• The employment contract structure.
• Whether the employer is a UK entity or overseas entity.
• The terms of any relevant social security agreement between the UK and the country of employment.

The annual allowance still applies to all contributions to registered UK pension schemes regardless of where the employer is based. If your overseas employer contributes to a UK SIPP, those contributions count towards the £60,000 annual allowance (or the tapered amount, if applicable).

4. Overseas pension schemes

Contributions to foreign pension schemes — such as a US 401(k), Australian superannuation, or UAE gratuity scheme — do not count towards the UK annual allowance. They are governed by the tax rules of the relevant country and any DTA provisions.

However, be aware that some expats transfer overseas pension benefits back to a UK registered scheme at a later date. If such a transfer is made, the rules around whether it constitutes a pension input amount need careful analysis.

5. Tax year timing and the PIP

Because all PIPs now align with the UK tax year (6 April to 5 April), expats who leave the UK or return mid-year need to consider in which tax year contributions fall.

For example, if you leave the UK on 1 July 2025, your departure tax year is 2025/26 (ending 5 April 2026). Any contributions made before you leave the UK in that tax year count in the 2025/26 PIP. Any contributions made after leaving (if you have UK-relevant earnings for that period) also count in the same PIP. The combined total must not exceed your applicable annual allowance for 2025/26.

If you are using carry forward of unused allowances from prior years (see below), the calculation must match PIPs precisely to the tax years in question.

Carry Forward and the Three-Year Rule

Carry forward allows unused annual allowance from the three previous tax years to be added to the current year's allowance, potentially allowing a contribution of up to £180,000 in a single year (plus the current year's £60,000). However:

• You must have been a member of a registered pension scheme in each of the years from which you are carrying forward.
• Your own personal contributions cannot exceed your UK-relevant earnings in the current tax year (even if the combined allowance is higher).
• Carry forward cannot be used to increase contributions beyond your relevant earnings limit.

For expats, carry forward is most useful in years of high UK-relevant earnings — for instance, the year of returning to UK employment after a period abroad, or a year of selling a UK business interest where the proceeds flow through as income.

Annual Allowance Charges: How They Work

If the total pension input amount in a tax year (across all schemes) exceeds your annual allowance (including any carry forward), the excess is subject to an annual allowance charge. This is calculated by:

1. Adding the excess to your total income for the year.
2. Applying your marginal income tax rate to the excess.

The charge is reported on your UK self-assessment return. Non-residents who still have UK pension contributions triggering a charge must still file a self-assessment return to declare and pay the charge.

Scheme pays: if the annual allowance charge exceeds £2,000 and the input amount in a single scheme exceeds the annual allowance, you can request that the scheme pays the charge on your behalf (reducing your pension fund accordingly). This must be requested by 31 July following the end of the tax year.

---

Pension Input Statements

Your pension scheme is required to issue a pension savings statement if:

• Your pension input amount in that scheme exceeds the standard annual allowance (£60,000) in a PIP.
• You request one.

For expats with multiple old UK pension schemes — deferred workplace pensions, SIPPs, and DB scheme benefits — obtaining pension savings statements from each is a vital annual exercise to track total pension input against the annual allowance. Many expats lose track of deferred scheme inputs, particularly from DB schemes, which continue to generate input amounts through revaluation even without active contributions.
