You are 58. You have stopped full-time work, or you are about to. The bridge between now and State Pension age needs funding, and the largest pot you own is the pension. Taking a taxable income payment from it looks like the obvious move.
It may well be the right move. But it is not a neutral one. One taxable withdrawal from a money purchase arrangement changes the contribution rules that apply to you, and it changes them from the tax year of the withdrawal onwards. That is the part of the decision that gets less attention than it deserves.
Two regimes, one switch
Most people saving into a pension operate under the standard annual allowance. GOV.UK describes it plainly: the annual allowance is the most you can save in your pension pots in a tax year before you have to pay tax, and it is £60,000 this tax year (GOV.UK, Tax on your private pension contributions). That figure applies across all your private pensions combined, including employer contributions.
There is a second regime. GOV.UK states that your annual allowance might be lower if you have flexibly accessed your pension pot, and gives two examples of what that can mean: taking cash or a short-term annuity from a flexi-access drawdown fund, or taking cash from a pension pot through an uncrystallised funds pension lump sum. The lower allowance is called the money purchase annual allowance (MPAA).
So the structure is not a penalty bolted onto a withdrawal. It is a switch between two sets of rules. Before the switch, your money purchase contributions are tested against £60,000. After it, they are tested against a much smaller number. The planning question is not whether the withdrawal is affordable. It is whether you have finished making the contributions you want to make.
What actually triggers it
The trigger events are set out in HMRC’s Pensions Tax Manual. The manual states that the MPAA test applies when an individual first flexibly accesses a money purchase arrangement in certain circumstances on or after 6 April 2015, and that if a trigger event occurs, the test applies for the tax year in which the event occurs and in subsequent tax years (PTM056520).
The list is longer than most people expect. It includes:
- A payment from a flexi-access drawdown fund that was newly designated on or after 6 April 2015. The trigger occurs immediately before the first payment is made.
- Converting a pre-6 April 2015 drawdown fund into flexi-access drawdown, where a payment is then made from the converted fund.
- Having qualified for flexible drawdown before 6 April 2015. Here the trigger occurs at the start of 6 April 2015, and HMRC notes there is no requirement for any actual payment to be made.
- An uncrystallised funds pension lump sum, triggered when the first such payment is made.
- A stand-alone lump sum paid to someone with primary protection and a protected tax-free lump sum right greater than £375,000.
- Becoming entitled to a lifetime annuity whose terms allow actual or possible decreases in the amount payable, other than in prescribed circumstances.
- A scheme pension under a money purchase arrangement where fewer than 11 other individuals were entitled to present payment under the same scheme.
- Payment of one of these benefit types from an overseas pension scheme that has benefited from tax relief.
Two things follow from that list. First, the size of the withdrawal is not the test. The manual describes trigger events in terms of the first payment, not a minimum amount. Second, several of these events are administrative or structural rather than a deliberate decision to draw income. Converting an old capped drawdown arrangement, or taking a small lump sum from an overseas scheme, can move you into the MPAA regime without it feeling like a retirement decision at all.
The number, and how it has moved
For tax year 2023-24 onwards, HMRC states the MPAA is £10,000 (PTM056510). The same manual records the history: £10,000 in 2016-17, £4,000 from 2017-18 to 2022-23, and £10,000 from 2023-24 onwards. The 2015-16 year was split into two mini tax years with different figures again.
The history matters for one reason. The allowance has been changed by legislation before, in both directions. Anyone treating the current £10,000 as a permanent feature of the landscape is making an assumption, not reading a rule. Plan on the figure that applies now, and accept that it can move.
The part most people miss: carry forward does not rescue you
Carry forward is the mechanism that lets you use unused annual allowance from earlier tax years. It is widely understood, and widely relied on by people with lumpy incomes who want to make large one-off contributions.
It does not work against the MPAA. HMRC states that any unused annual allowance carried forward from previous tax years is added to the alternative annual allowance, not to the money purchase annual allowance (PTM056510). The manual also states that any unused money purchase annual allowance cannot be carried forward to later tax years.
So the asymmetry is this. Carry forward can enlarge the allowance that applies to defined benefit accrual. It cannot enlarge the £10,000 that applies to your money purchase contributions. If you trigger the MPAA while you still have significant money purchase contributions ahead of you, carry forward is not the escape route.
If you have a defined benefit pension, the calculation splits
This is where the practical complexity sits, and it is worth being precise.
HMRC describes a split test. Money purchase pension input amounts are tested against the MPAA. Other pension input amounts, essentially defined benefit accrual, are tested against what the manual calls the alternative annual allowance. For 2023-24 onwards, that alternative annual allowance is £30,000 or a lesser amount where the tapered annual allowance also applies (PTM056510).
Carry forward is added to the alternative annual allowance. It is not added to the MPAA. And where the MPAA is exceeded, the manual sets out a comparison between an alternative chargeable amount and a default chargeable amount, with the greater of the two being the amount subject to the annual allowance charge.
The practical consequence: if you have a defined benefit scheme and you trigger the MPAA, you have not capped all your pension saving at £10,000. You have capped your money purchase inputs at £10,000 and moved your defined benefit accrual onto a different, lower allowance. Those are different problems with different answers, and they need to be worked through separately.
The sequencing question
Here is the argument I would put to a couple in their late fifties with £300,000 or more spread across pensions, ISAs and property, still contributing, and needing cash before State Pension age.
The MPAA is a sequencing problem, not a saving problem. The decision is not whether to withdraw money. It is whether you have finished making the contributions you want to make. If you have, the MPAA is largely irrelevant to you and you can draw what you need. If you have not, the order in which you take money from your various pots matters more than the withdrawal itself.
Three broad routes, in ascending order of consequence:
Use non-pension pots first. If the cash need is temporary, or if you are still contributing meaningfully, drawing from ISAs or cash reserves preserves your full money purchase allowance. This is a planning judgement, not a rule. It depends on your tax position, your cash flow, and whether the ISA money was earmarked for something else.
Take only the tax-free element. Where the need is a lump sum rather than an income, the tax-free portion of a pension commencement lump sum is the part that does not create a taxable payment. I am deliberately not going further than the retrieved HMRC material supports on what does and does not trigger the MPAA, because the manual’s trigger list is framed around taxable payments and specific events rather than around a general exemption list. If this route matters to your decision, get written confirmation from the scheme and from your adviser before you act.
Accept the trigger. If the contribution phase is genuinely over, or if the cash need is recurring and the pension is the right source, then triggering the MPAA is simply the cost of the decision. It is not a mistake. It is a trade, and it should be made with the number in front of you.
What to ask before you sign anything
The useful adviser question is not “what is the MPAA?” Most people reading this already know. The useful question is narrower and more uncomfortable:
Which of my pension inputs are tested against which allowance, and is carry forward available for the defined benefit side only?
Ask for it in writing. If you have both money purchase and defined benefit arrangements, the answer should show the two tests separately. If you have already triggered the MPAA, the answer should show the tax year of the trigger event and confirm which subsequent years are affected.
There is a second question worth asking, and it connects to the wider work of auditing an adviser relationship. If a taxable withdrawal is being recommended, what is the stated reason, and has the effect on your remaining contribution headroom been documented? A recommendation that produces a permanent change to your allowance should say so on the page, not leave you to discover it later.
If you are still some years from the decision, the groundwork is worth doing now. The question of what you are actually trying to achieve with the money, and in what order, is the one that makes the MPAA decision straightforward when it arrives. That is the subject of The Question You Should Be Asking Years Before You Retire.
Frequently asked questions
Does the MPAA apply to all my pensions or just the one I withdrew from?
It applies to your money purchase pension inputs across all your arrangements combined. The £10,000 is a single allowance, not a per-scheme allowance. HMRC’s manual describes the test in terms of an individual’s money purchase pension input amounts, not per scheme.
Can I use carry forward to get back above £10,000?
No, not for money purchase contributions. HMRC states that unused annual allowance carried forward is added to the alternative annual allowance, and that unused money purchase annual allowance cannot be carried forward. Carry forward can help with defined benefit accrual, not with the MPAA itself.
I triggered the MPAA years ago. Does it still apply?
HMRC states the test applies for the tax year in which the trigger event occurs and in subsequent tax years. The manual does not describe a mechanism for resetting it. If you are unsure of your position, check your pension statements for drawdown income payments or uncrystallised funds pension lump sums, and ask the scheme directly.
I have a defined benefit pension as well. Am I limited to £10,000 in total?
No. The calculation splits. Money purchase inputs are tested against the MPAA. Other inputs, essentially defined benefit accrual, are tested against the alternative annual allowance, which HMRC states is £30,000 or a lesser amount for 2023-24 onwards where the tapered annual allowance applies. Carry forward is added to the alternative annual allowance.
What happens if I exceed the MPAA?
HMRC’s manual sets out a comparison between the alternative chargeable amount and the default chargeable amount, with the greater amount subject to the annual allowance charge. The detail matters and the arithmetic is not trivial. This is a calculation to have checked rather than estimated.
Does the MPAA figure ever change?
It has changed before. HMRC records £10,000 in 2016-17, £4,000 from 2017-18 to 2022-23, and £10,000 from 2023-24 onwards. Treat the current figure as the rule that applies now, not as a permanent feature.
The uncomfortable truth, stated plainly
A taxable withdrawal from a money purchase pension is not reversible in the way most financial decisions are. You can change your mind about an ISA contribution. You can stop a regular saving plan. You cannot un-trigger the MPAA.
That does not make it a trap. It makes it a decision with a long tail, and decisions with long tails deserve to be made deliberately. If you are still contributing, and you expect to keep contributing, the sequencing question is the one to answer first. If you are not, the MPAA is a footnote to a decision you have already made.
Either way, the number is £10,000 for money purchase inputs from 2023-24 onwards, the trigger is the first taxable payment or the relevant event, and the effect runs from that tax year forward. Those are the facts. What you do with them is a planning judgement, and it is better made with the arithmetic on the table than discovered afterwards.
