MPAA Explained: What Triggers It and How to Avoid It

Quick answer

The Money Purchase Annual Allowance (MPAA) cuts the amount you can pay into defined contribution pensions with tax relief from £60,000 to £10,000 a year. It is triggered when you first take taxable income flexibly from a pension, for example through drawdown. Taking only your tax-free cash does not trigger it. Once triggered, it is permanent.

If you plan to dip into your pension while you are still working and paying in, there is one rule that can quietly slash how much you are allowed to save. It catches a surprising number of people. This guide is part of our complete guide to UK retirement rules.

01What does the MPAA do?

Normally you can pay up to £60,000 a year into pensions and get tax relief, or 100% of your earnings if that is lower. That is the Annual Allowance.

Once you trigger the MPAA, the limit for defined contribution pensions drops to £10,000 a year. That limit includes your employer's contributions, not just your own. Go over it and you pay a tax charge at your marginal rate on the excess.

02What triggers the MPAA, and what does not?

Triggers the MPAA	Does not trigger the MPAA
Taking taxable income from flexi-access drawdown	Taking only your 25% tax-free cash and leaving the rest in drawdown untouched
Taking a lump sum straight from your pot (UFPLS), where 75% is taxable	Buying a standard lifetime annuity
Cashing in a whole pension worth more than £10,000	Cashing in a small pot of £10,000 or less under the small pots rules
Buying a flexible or investment-linked annuity whose income can go down	Taking income from an old capped drawdown plan within its limit
Going over the income limit on an old capped drawdown plan	Taking a defined benefit (final salary) pension

The pattern is simple. Tax-free cash is safe. Taxable income taken flexibly is the trigger.

The small pots rule is worth knowing. You can cash in up to three personal pensions of £10,000 or less each, and any number of workplace pots that size, without triggering the MPAA.

03Why does it catch people out?

The classic trap is a one-off taxable withdrawal while still in work. Perhaps to clear a debt, help a child with a deposit or tide things over. It can be a few hundred pounds. It still triggers the MPAA, and it does so for good.

People often only find out later, when they or their employer are paying in more than £10,000 a year between them.

Illustrative example

You earn £70,000. You pay 8% into your workplace pension and your employer pays 10%. That is £12,600 a year in total.

At 57 you take £5,000 of taxable income from an old pension to pay for a new kitchen. The MPAA now applies.

Your contributions are £2,600 over the £10,000 limit every year. As a higher-rate taxpayer, that is a tax charge of about £1,040 a year, unless you or your employer cut what is paid in.

04What else do you lose?

Carry forward

Normally you can use unused Annual Allowance from the previous three tax years to make a large one-off contribution. Once the MPAA applies, you cannot use carry forward for defined contribution savings. The £10,000 stands on its own.

Flexibility to rebuild

If you later receive a bonus, inheritance or redundancy payment and want to put it into a pension, the MPAA sharply limits how much you can pay in tax-efficiently.

05What must you do once it is triggered?

Your provider must send you a "flexible access statement" within 31 days. You then have 91 days to tell any other pension scheme you are actively paying into. There are penalties for not doing so.

06How can you avoid it?

If you need a lump sum while still working, see whether your tax-free cash alone would cover it.
If you have a small pot of £10,000 or less, cashing that in may meet the need without triggering the MPAA.
Think twice about the "small first withdrawal" tactic for avoiding emergency tax if you are still contributing. Any taxable withdrawal is a trigger.
Use ISAs or cash savings first if you have them.
Ask your provider, in writing, whether what you plan to do will trigger the MPAA before you do it.

Key takeaways

The MPAA cuts your defined contribution allowance from £60,000 to £10,000 a year.
It is triggered by taking taxable income flexibly, not by taking tax-free cash.
Employer contributions count towards the £10,000.
Small pots of £10,000 or less can be cashed in without triggering it.
It is permanent, and carry forward is lost.

07Frequently asked questions

Is the MPAA permanent?

Yes. Once triggered, it applies for every future tax year.

Does taking my 25% tax-free cash trigger the MPAA?

No. Taking only tax-free cash does not trigger it, even if the rest of the pot moves into drawdown, as long as you take no taxable income.

Does the MPAA matter if I have stopped working?

Usually not. If you have no earnings, you can only get tax relief on contributions of up to £3,600 a year anyway. It matters most to people who are still working or may return to work.

Does it affect a final salary pension?

The £10,000 limit applies to defined contribution savings. If you are also building up a defined benefit pension, a separate allowance applies to that.

Has the MPAA always been £10,000?

No. It was £4,000 until 5th April 2023 and has been £10,000 since.
