The Slope, Not the Cliff: How Pension Allowance Tapering Works for High Earners in 2026/27

Why the £60,000 figure can mislead

For many people, the pension annual allowance is a simple number: £60,000 for 2026/27. That is the standard allowance, and it is the figure most often quoted in pension planning. But for higher earners, the allowance is not fixed. Once income passes certain thresholds, it reduces gradually. The reduction is often described as a taper, and it is one of the more easily missed features of the self-assessment system.

The taper does not operate as a cliff edge at £260,000. It is a slope. The allowance begins to shrink once adjusted income exceeds £260,000, and it continues to shrink by £1 for every £2 of excess income until it reaches a floor of £10,000. For anyone whose income fluctuates, or whose employer makes large pension contributions, the practical result can be an annual allowance charge that only becomes clear after the tax year has ended.

The two income tests

The taper uses two measures of income: threshold income and adjusted income. Both matter, and they are not the same.

Threshold income is broadly your taxable income after certain reliefs, but before pension contributions are taken into account. If your threshold income is £200,000 or less, the taper does not apply, even if your adjusted income is above £260,000. This is a common point of confusion. A high adjusted income on its own is not enough to trigger the taper; the threshold income test must also be met.

Adjusted income starts with threshold income and adds pension contributions, including employer contributions. This is why a generous employer pension contribution can matter so much. Someone with a salary below £260,000 can still have an adjusted income above that figure once employer contributions are included. The pension input is not just the money deducted from pay; it also includes the amount the employer pays in.

How the reduction works

Once both tests are met, the annual allowance is reduced by £1 for every £2 of adjusted income above £260,000. The reduction continues until the allowance reaches £10,000. In practice, the allowance is fully tapered at £360,000 of adjusted income.

For example, suppose your adjusted income for 2026/27 is £300,000. The excess above £260,000 is £40,000. Half of that is £20,000, so the standard £60,000 allowance is reduced to £40,000. If your adjusted income is £360,000, the excess is £100,000, half is £50,000, and the allowance falls to £10,000. Above £360,000, the allowance remains at £10,000.

The calculation sounds straightforward, but the inputs are not always obvious. Adjusted income includes employer contributions, and it can include contributions made under net pay arrangements. It may also be affected by trading losses, gift aid, and other reliefs. For anyone near the thresholds, a rough estimate is not usually enough.

Carry forward is not a clean slate

Carry forward allows unused annual allowance from the previous three tax years to be used in the current year. For 2026/27, the relevant years are 2023/24, 2024/25 and 2025/26. This can be valuable for someone with a one-off pension contribution or a fluctuating income pattern.

However, carry forward does not override the taper. If your allowance was tapered in an earlier year, the unused amount from that year is based on the tapered allowance, not the standard £60,000. Someone who assumes three years of £60,000 carry forward may be working with a much smaller reserve. The pension savings statements for those years should be checked before relying on carry forward.

The order of use also matters. The current year’s allowance is used first, followed by carried-forward amounts from earlier years. If the current year is tapered, the starting point is already lower. Carry forward can then absorb some of the excess, but only to the extent that unused allowance genuinely exists.

When an annual allowance charge applies

If pension contributions exceed the available annual allowance, the excess is subject to the annual allowance charge. The charge is taxed as income at your marginal rate. It is not a standalone penalty; it is a recovery of tax relief that was given on contributions above the permitted amount.

Your pension scheme should issue a pension savings statement if your pension input exceeds the standard annual allowance. For 2026/27, that statement should normally be provided by 6 October 2027. The statement is not a tax bill. It is a record of the pension input amount, and it helps you work out whether a charge arises once your tapered allowance and any carry forward are taken into account.

The charge is reported through self-assessment. The 2026/27 return is due online by 31 January 2028. If the charge is more than £2,000, it may be possible to ask the scheme to pay it from your pension pot under scheme pays, but this reduces the fund and should not be treated as a free option.

A practical check before the filing deadline

Start by gathering the pension savings statements for 2026/27 and the three earlier tax years. Then calculate threshold income and adjusted income, taking care to include employer contributions in the adjusted income figure. Compare the available allowance with the total pension input, including any carry forward you intend to use.

If the figures are close to the thresholds, seek advice before making further contributions. The taper is gradual, but the reporting obligation is not optional. A timely check is far easier than correcting a return after the 31 January 2028 deadline.
