Pension Annual Allowance Calculator (Tapered)

The annual allowance is £60,000, and for most savers that is the whole story. For higher earners it is a moving ceiling, and the mechanism is unusual: two separate income measures, both of which must be breached before anything happens.

Threshold income is broadly net income before pension relief. If it is £200,000 or less, the taper cannot apply at all — no matter how large adjusted income is. Adjusted income is broadly total income plus all pension input, employer contributions included, and it only matters once the threshold gate has been passed. Above £260,000 of adjusted income, the allowance falls by £1 for every £2 of excess, down to a floor of £10,000.

The asymmetry between the two is the planning point. Adjusted income includes employer contributions, so it climbs with pension saving itself and is largely outside the saver’s control. Threshold income does not include employer contributions and IS reduced by personal contributions — so an individual contribution can pull threshold income below £200,000 and remove the taper entirely, restoring far more allowance than the contribution used. That is a rare case of a pension contribution being worth substantially more than its own tax relief.

The most damaging misunderstanding in this area is what "pension input" means. In a defined contribution scheme it is simply the money paid in. In a defined benefit scheme it is the growth in the capital value of the promised benefits over the year, valued at sixteen times the increase in annual pension — and it bears no relationship to any cash that changed hands.

The consequence is that a promotion, or a year of unusually high pensionable pay, can generate a pension input amount of tens of thousands of pounds while the member’s payslip deductions barely move. Combined with a taper the member may not know applies, this produces a tax charge on money they never saw, could not have declined, and cannot access for decades. That is the NHS annual allowance crisis in one paragraph, and it was serious enough that the government eventually raised the thresholds specifically to defuse it.

The practical defence is documentary. Schemes must issue a pension savings statement where input exceeds the standard allowance, and members can request one otherwise. That statement, not a payslip or a contribution schedule, is the figure this calculation needs.

Carry forward is what rescues most people who find themselves over. Unused allowance from the previous three tax years can be added to the current year, used oldest first because the oldest expires first. A saver whose input has been modest for several years can often absorb a large single year without any charge — which is why establishing carry forward should come before accepting any bill.

There is one place carry forward does nothing at all. Once a money purchase pot has been flexibly accessed — a taxable lump sum, drawdown income, certain short-term annuities — money purchase input is permanently capped at £10,000 a year, and carry forward cannot be set against that cap. A saver who took money from a pension at 55 and later returns to well-paid work discovers that their pension saving is limited to £10,000 regardless of how much unused allowance they have accumulated. The trigger is irreversible.

Where a charge does arise, it is income tax on the individual, but it need not be paid from other money: where the charge exceeds £2,000 and the input exceeds the standard allowance, a member can generally require the scheme to settle it in exchange for a reduction in benefits. Scheme pays turns an immediate cash problem into a smaller pension, which for a large defined benefit charge is often the only practical answer.
