Armed forces pension lump sum explained

The automatic lump sum in AFPS 75 and AFPS 05

If you served on AFPS 75 or AFPS 05, the lump sum is the easy part: it arrives automatically and you do not have to do anything to trigger it. When your pension comes into payment you receive a tax-free lump sum equal to three times your annual pension, paid on top of the pension itself. On AFPS 75 this is bundled into what the scheme calls the Immediate Pension, the combined annual pension and lump sum paid to those who leave at the right point (officers after 16 years' service from age 21, other ranks after 22 years from age 18).

The important thing is that you do not give up any pension to get this money. The three-times lump sum is separate from your annual income, so your yearly pension is unaffected by it. That is the headline difference from AFPS 15, where the only way to get cash up front is to trade away some of your annual pension for it.

The lump sum is paid once, at the start, and there is nothing to opt into or calculate: take your pension and the cash comes with it. Both legacy schemes work the same way on this, whether your normal pension age is 60 on AFPS 75 or 65 on AFPS 05.

AFPS 15 has no automatic lump sum

AFPS 15 works differently, and because it is the scheme everyone still serving now builds their pension in, this is the one that matters most for current personnel. It does not hand you a lump sum as of right. There is no automatic three-times payment. If you want tax-free cash at the point you draw your pension, you have to create it yourself by commuting part of your annual pension.

Commuting simply means giving up some of your yearly pension in exchange for a one-off cash sum. It is entirely optional: take none and you keep your full annual pension, or take some and accept a permanently lower income for the rest of your life in return for money now. Whether that trade is worth it depends on your circumstances, so it is a judgement to weigh rather than a default to reach for.

Commuting AFPS 15 pension: £12 for every £1

The rate for AFPS 15 commutation is fixed and scheme-wide, which makes it refreshingly simple to work out. For every £1 of annual pension you surrender, you receive £12 of tax-free lump sum. So giving up £1,000 a year of pension would hand you a £12,000 lump sum, and your annual pension would drop by that £1,000 permanently, then rise with inflation from the lower base thereafter.

There is a ceiling. HMRC rules cap the lump sum at 25% of the capitalised value of your pension benefits, so you cannot commute your whole pension into cash. Because the £12 to £1 factor never changes with age, this is the one commutation case that can be modelled exactly, and our commutation calculator does just that. If you want the mechanics in more depth, the commutation guide walks through it step by step.

It is all paid tax-free

One thing holds true across every scheme: the lump sum is paid free of income tax. Whether it is the automatic three-times payment on AFPS 75 or AFPS 05, or a sum you have commuted from an AFPS 15 pension, the cash lands in your account without a tax deduction. That is a large part of why a lump sum is attractive, and why the commutation trade can look appealing even though you are giving up taxable annual income to get it.

Tax-free does not mean unlimited, though. The freedom applies up to a cap set by HMRC, which is where the Lump Sum Allowance comes in. For most service leavers it never bites, but it is worth understanding so you know whether it applies to you.

The Lump Sum Allowance cap

HMRC sets an overall limit on the total tax-free lump sums you can take across all your pensions in your lifetime, known as the Lump Sum Allowance. It is not a per-scheme figure but a running total: lump sums from your armed forces pension count towards it alongside any tax-free cash from a civilian workplace pension or a private one. Take more than the allowance and the excess is taxed at your marginal rate rather than paid tax-free.

For most service leavers the allowance sits comfortably above the lump sums their armed forces pension alone produces, so it rarely bites. It is more likely to matter if you have built up substantial pensions elsewhere, or if you are combining a large automatic lump sum with other tax-free cash. Our Lump Sum Allowance guide sets out the current figure and how to check whether you are anywhere near it.

Extra commutation in the legacy schemes

The automatic three-times lump sum is not necessarily the end of the story for AFPS 75 and AFPS 05. Both legacy schemes also allow certain additional one-off commutation options, most commonly resettlement commutation, which lets some leavers convert a further slice of pension into cash on top of the automatic amount.

Unlike the flat £12 to £1 rate in AFPS 15, these legacy options use age-banded factor tables published by the Government Actuary's Department (GAD). The factor depends on your exact age in years and months at the relevant date, so there is no single multiplier and the figures cannot be reduced to one rate a general calculator can reproduce. If your service falls under one of these routes, read our commutation factors guide and get an official figure before you rely on any estimate.

How to work out your own lump sum

The quickest way to see roughly what your lump sum could be is to model it. For AFPS 75 or AFPS 05, it is three times whatever annual pension your service produces, paid automatically. For AFPS 15, use the commutation calculator to see how much cash a given percentage of commuted pension would give you at the fixed rate, and what it costs you in annual income.

Whatever the figure, treat it as a planning estimate rather than a promise.

Before you make a decision that turns on the exact amount, especially an irreversible one like commuting AFPS 15 pension, confirm the figures with an official Veterans UK forecast and, for the bigger calls, take regulated advice.
