Why your AFPS 75 pension increases at 55

If you left the Armed Forces in your late thirties or forties on an AFPS 75 Immediate Pension, you have probably noticed two things. Your pension has sat at the same flat figure for years, and somewhere along the way you were told it would rise, sometimes sharply, when you turn 55. If you went looking for a clear explanation of why, you most likely did not find much. This article is that explanation.

It matters most to one particular group: people drawing an AFPS 75 Immediate Pension who left before age 55 and gave up part of that pension for a tax-free lump sum, a choice called commutation. If that is you, the change at 55 can be large, large enough to feel like a mistake. It is not a mistake, and it is not a windfall the scheme will later take back. It is written into the rules, and it has a logic worth understanding.

For the full picture of how AFPS 75 sits alongside AFPS 05 and AFPS 15, see our Armed Forces Pension Scheme explainer. This piece zooms in on a single event: what happens to an AFPS 75 Immediate Pension at 55, and why.

The Immediate Pension, and why it sits flat until 55

The AFPS 75 Immediate Pension is one of the most distinctive features in any UK public service pension. If you reach the Immediate Pension Point, sixteen years’ reckonable service from age 21 for officers, or twenty-two years from age 18 for other ranks, you can leave and start drawing a pension and a tax-free lump sum on the day of discharge, even if you are still in your thirties. There is no reduction for taking it early. No other public service scheme offers anything quite like it.

The trade-off is what happens to the figure between leaving and age 55. During those years it is paid at a flat rate. It does not rise with inflation. A pension of, say, £9,000 a year is still £9,000 a year a decade later, even though the cost of living has climbed in the meantime. This is not an oversight. Public service pensions paid before age 55 are generally not increased year on year under the rules that govern pension uprating, with limited exceptions such as ill-health and dependants’ pensions.

The important point is that the annual increases are not lost. They are held back and applied in a single step when you reach 55. So the flat years are not years of forgone inflation. They are years of deferred inflation, and the deferral is settled in full on your 55th birthday.

Commutation: trading pension for a lump sum

When you left, you received an automatic tax-free lump sum worth three times your annual pension. That is built in and you do not have to ask for it. Separately, you could choose to give up a further slice of your annual pension in exchange for more tax-free cash. That choice is commutation, and it is why your monthly pension may be noticeably lower than the full figure on your award paperwork.

Commutation is a fair exchange in principle. You hand back some future annual income, and in return you receive a lump sum now. People commute for all sorts of sensible reasons: clearing a mortgage, funding the move to civilian life, or putting capital to work in a second career. The cost is a smaller monthly pension.

Here is the part that catches people out, and the part most online explanations miss. Under AFPS 75, the commutation reduction only runs until age 55. It is not a permanent, lifelong cut. The years of reduced pension before 55 are how the lump sum is effectively accounted for. Once you reach 55, that job is done, and your pension climbs back to its full, uncommuted level.

What actually happens on your 55th birthday

On your 55th birthday, two effects land at the same moment:

1. The commutation reduction ends. Your pension reverts to the full amount you would have had if you had never commuted.
2. The stored-up inflation is applied. Every annual CPI increase from your leaving date to now is added in one go.

Stacked together, these two effects can lift the monthly figure a long way. The longer you have been retired, and the more you commuted, the bigger the step up. Someone who left fifteen or more years ago, through a period of high inflation, and who commuted heavily, can see the pension more than double overnight.

You keep your lump sum

A common worry is that the restored pension somehow repays the lump sum, or that the bigger pension comes with a hidden cost later on. It does not. The tax-free cash you took on leaving is yours. The reduced pension you received before 55 was the price of that cash, and AFPS 75 limits that price to the years before 55. After 55 you have both: the lump sum you long since spent or invested, and the full pension.

This is why the restoration feels so generous to those who commuted the maximum. They spent years on a visibly reduced pension, and then, in a single month, not only does the reduction vanish but the full pension arrives uprated for every year of inflation since they left.

The tax side: what the jump can trigger

A sharp rise in income can have tax consequences, and it is worth knowing what to expect rather than being surprised by your first restored payment.

If your flat-rate pension sat below the personal allowance, you may have paid no income tax on it at all. Once it is restored, the higher figure can take you over the allowance, and income tax may begin for the first time. Your tax code may change to reflect it. The first payment or two after your birthday can carry uneven deductions while HMRC updates your code, so an early figure may not be a reliable guide to the settled monthly amount.

Armed forces pensions are taxed at source through PAYE, wherever in the world you live, because they are UK-source income. If the pension is your only UK income, the sums are usually straightforward once the code settles. If you have other income, the picture is more involved. This is general information rather than advice, and a quick read of the relevant pages on MoneyHelper is a sensible first step if you want to understand your own position.

When you will see it, and how to check your figures

The change is tied to your 55th birthday, not to the April uprating that other pensioners see. A few practical points:

• The increase often takes effect part-way through the month of your birthday, so your first higher payment may be a part-month blend rather than a clean full month.
• Veterans UK should issue a revised award notification around this time. If nothing arrives, it is worth chasing rather than assuming the figure is wrong.
• Check your payslip and your tax code against the new figure, and keep the award notification with your records.

For the exact numbers in your case, your AFPS 75 award paperwork and Veterans UK are the authorities. Veterans UK, through the Joint Personnel Administration Centre, can confirm your full uncommuted pension and what the restoration produces. The free pension queries line is 0800 085 3600. The scheme rules themselves are published as JSP 854 on gov.uk, although for most people a call to Veterans UK is the quicker route to a personal figure. If the figures come back and they are lower than you were expecting, or a letter arrives saying you have been overpaid and the money will be recovered, that is a separate situation with its own process and its own defences: see told to repay your Armed Forces pension.

After 55, it rises every year

Once restored, your AFPS 75 pension behaves like any other pension in payment. It is increased each April in line with CPI under the annual Pensions Increase. The flat-rate years are behind you. From here it keeps pace with inflation for life, and armed forces pensions continue to be uprated wherever in the world you are resident, which is not always true of the State Pension.

This is specifically an AFPS 75 feature

The flat-then-restored pattern applies to the AFPS 75 Immediate Pension taken before 55. It is not how AFPS 05 or AFPS 15 work. Those schemes use the Early Departure Payment and a preserved pension on different terms, and the numbers behave differently. If your AFPS 75 benefits only come into payment at or after 55, you will not see this step change either, because the pension starts on the full basis rather than the reduced one. Our main Armed Forces Pension Scheme explainer sets out how the three schemes differ and where the McCloud remedy fits.
