For most people saving into a SIPP, the standard pension annual allowance is the only limit that matters. But for anyone who has already started drawing a taxable income from a defined contribution pension — whether through flexi-access drawdown or by taking an uncrystallised funds pension lump sum — a much lower limit can quietly kick in: the Money Purchase Annual Allowance, or MPAA. Understanding when the MPAA is triggered, and how sharply it restricts future contributions, matters for anyone considering accessing pension money early while they, or their employer, still want to keep contributing.
What the Money Purchase Annual Allowance is
The MPAA is a reduced annual allowance that applies specifically to contributions into defined contribution ("money purchase") pension schemes, once an individual has started taking certain types of taxable income from such a scheme. Where the standard annual allowance for 2025/26 is £60,000 (or 100% of earnings if lower), the MPAA is set at a much lower figure once triggered, sharply limiting how much can subsequently be paid into a money purchase pension while still benefiting from tax relief without incurring a tax charge.
Why it exists
The MPAA was introduced to prevent a form of "recycling," where an individual could draw a tax-free lump sum or taxable pension income and then immediately recontribute that same money back into a pension to claim a further round of tax relief on top of what they had already received — effectively getting favourable tax treatment twice on the same pool of money. By capping further contributions once income has been drawn, the MPAA closes off this particular route while still allowing modest ongoing contributions for those who continue working while also drawing some pension income.
What actually triggers the MPAA
Not every way of accessing a pension triggers the MPAA — the rules distinguish between actions that count as accessing genuinely taxable income and those that do not.
Actions that typically trigger the MPAA
- Taking taxable income from a flexi-access drawdown arrangement.
- Taking an uncrystallised funds pension lump sum (UFPLS), where part is tax-free and part is taxable income.
- Taking a scheme pension from a money purchase arrangement with fewer than a certain small number of other pensioners in the scheme.
- Cashing in a small pension pot in certain circumstances, depending on the specific method used.
Actions that typically do not trigger the MPAA
- Taking only the tax-free lump sum (commonly up to 25% of the pot, subject to overall limits) without drawing any taxable income from the remaining pot.
- Moving a pension into flexi-access drawdown but not yet withdrawing any taxable income from it.
- Receiving income from a defined benefit (final salary) pension, since the MPAA applies specifically to money purchase arrangements.
- Certain small, specific lump sum payments that fall under separate "trivial commutation" or small pot rules, though the precise boundaries here are technical and worth checking carefully.
This distinction matters considerably in practice: an individual can access the tax-free portion of their pension without restricting future contributions, but as soon as they draw taxable income from a money purchase pot, the lower MPAA applies from that point onward for the rest of their life, even if they later stop drawing income.
How the MPAA changes contribution planning
The reduced allowance is far lower than the standard allowance
Once triggered, the MPAA replaces the standard money purchase annual allowance with a much smaller figure, meaning contributions from all sources — personal, employer, and any tax relief added — combined must stay within this lower limit across a tax year to avoid an unwelcome tax charge. This can come as a surprise to individuals who assumed their full £60,000 standard allowance (2025/26) remained available simply because they were still working and still contributing to a workplace pension.
No carry forward once triggered
Under the standard annual allowance, unused allowance can be carried forward from the previous three tax years, which lets higher earners or those with variable income smooth out large contributions in some years. Once the MPAA applies, this carry-forward mechanism is not available for money purchase contributions above the MPAA limit — the reduced limit applies strictly to that tax year going forward, with no ability to use unused allowance from earlier years to increase it.
Impact on employer contributions too
It is a common misunderstanding that the MPAA only limits an individual's own personal contributions. In fact, the MPAA applies to the total of personal contributions, employer contributions, and any tax relief added together — so an individual who continues working after triggering the MPAA needs to consider their employer's contribution rate carefully, since employer contributions alone could push the total over the reduced limit even without any personal contribution at all.
Comparing standard and triggered allowances
| Feature | Standard annual allowance | Money Purchase Annual Allowance (once triggered) |
|---|---|---|
| 2025/26 limit | £60,000 (or 100% of earnings if lower) | Much lower fixed figure — check current HMRC rules |
| Carry forward from previous 3 years | Available | Not available for money purchase contributions |
| Applies to | All pension contributions (money purchase and defined benefit) | Specifically money purchase contributions, once triggered |
| Trigger event | None — applies by default | Taking taxable income via drawdown or UFPLS from a money purchase pot |
A worked example
Suppose a 58-year-old with a £300,000 SIPP decides to take a modest UFPLS withdrawal to help cover a period of reduced work, drawing £10,000 gross, of which 25% is tax-free and the remainder taxable as income. This withdrawal triggers the MPAA. The individual continues working part-time and their employer continues contributing to a separate workplace pension at 5% of salary, alongside a small personal contribution the individual had been making. Once the MPAA applies, the combined total of the employer's contribution, the individual's own contribution, and any tax relief must stay within the reduced MPAA limit for that tax year onward, rather than the much larger standard £60,000 allowance. If the combined contributions from both sources happen to exceed the reduced limit, the excess may be subject to a tax charge, clawing back some of the tax relief previously given. This is a simplified, hypothetical example intended to illustrate the mechanism, not a description of any individual's actual circumstances or a recommendation to take pension income at any particular age.
Why this matters more for certain groups
Those combining part-time work with early pension access
An increasingly common pattern involves individuals in their late fifties or sixties reducing their working hours and topping up their income by drawing partially from a pension, while still earning enough from part-time or consultancy work to want to keep contributing to a pension. This group is precisely the one most likely to be caught out by the MPAA, since the natural assumption — that a modest pension withdrawal alongside continued part-time earnings leaves plenty of room for further tax-efficient saving — no longer holds once the reduced allowance applies.
Business owners drawing flexibly from their own pension
Self-employed individuals and small business owners sometimes use pension drawdown flexibly to manage variable income, drawing more from the pension in leaner years and contributing more from business profits in stronger years. Once the MPAA is triggered, this kind of flexible back-and-forth becomes considerably more constrained, since the capacity to make large "catch-up" contributions in a strong year is sharply limited by the reduced allowance, with no carry forward available to help.
Those who have not yet decided on a definitive retirement date
Many people do not stop working abruptly on a single retirement date, but instead wind down gradually over several years. For this group, the decision of when — or whether — to start drawing any taxable pension income deserves particular care, since an early, seemingly low-stakes withdrawal taken to smooth a temporary gap in income can have a lasting effect on pension contribution capacity for many subsequent working years.
How the MPAA interacts with tapering for high earners
Separately from the MPAA, the standard annual allowance can also be tapered down for very high earners, reducing the standard £60,000 allowance for those with sufficiently high adjusted income. Where an individual is both a high earner and has triggered the MPAA, it is the lower of the two relevant limits that constrains their money purchase contributions — meaning a high earner who has triggered the MPAA does not get the benefit of whichever figure happens to be larger. This combination is relatively unusual but worth being aware of for anyone with substantial income who is also considering flexible access to a pension before fully retiring, since the interaction between the two sets of rules can be more restrictive than either rule considered on its own.
Practical considerations before triggering the MPAA
Consider the tax-free lump sum route first
For those who need access to some pension money but intend to keep contributing significantly in future, taking only the available tax-free lump sum — without drawing any taxable income — avoids triggering the MPAA altogether, preserving the full standard annual allowance for continued contributions.
Think about timing relative to peak earning and contribution years
Triggering the MPAA earlier than necessary, for example to cover a temporary cash flow gap, can be costly if it happens during a period when an individual (or their employer) would otherwise have wanted to make larger pension contributions, such as during a run of high-earning years before retirement.
Review scheme rules carefully
The precise triggers, especially around small pot withdrawals and certain scheme pension arrangements, can be technical, and different schemes may handle these situations slightly differently in practice. Anyone considering an early withdrawal while still wanting to contribute significantly in future may find it worth checking the specific rules of their scheme and current HMRC guidance before acting.
Key takeaways
- The MPAA is a reduced pension annual allowance, well below the standard £60,000 (2025/26) allowance, that applies once certain types of taxable income are drawn from a money purchase pension.
- Taking only a tax-free lump sum, without drawing taxable income, generally does not trigger the MPAA.
- Taking taxable income via flexi-access drawdown or a UFPLS typically does trigger it, applying from that point onward.
- The MPAA applies to combined personal contributions, employer contributions, and tax relief together, and does not allow carry forward from previous years.
- Triggering the MPAA earlier than necessary can materially restrict contribution flexibility during later working years.
- Always check current HMRC figures and scheme-specific rules, as thresholds and detailed triggers can change.
