The MPAA and Part-Time Retirement: Managing Pension Contributions After Accessing Drawdown

The money purchase annual allowance (MPAA) is a reduced annual pension contribution limit that applies once you have taken any taxable income from a flexi-access drawdown arrangement or an uncrystallised funds pension lump sum (UFPLS). As of 2026–27, the MPAA is £10,000 per year — a significant reduction from the standard annual allowance of £60,000. For individuals who enter partial or phased retirement while continuing to work, the MPAA creates important constraints that require careful planning.

Why the MPAA exists

The MPAA was introduced in April 2015 alongside the pension freedoms legislation to prevent "recycling" — the practice of accessing pension income and immediately re-contributing it to a pension, claiming fresh tax relief on the same money. Without the MPAA, individuals could take taxable income from drawdown and simultaneously receive employer pension contributions (and contribute personally), effectively obtaining repeated tax relief on the same underlying capital.

The MPAA prevents this by limiting the amount that can go into a money purchase pension in any year once drawdown income has commenced. It applies to money purchase pensions only; it does not restrict future accrual in a defined benefit scheme (for which a separate "alternative annual allowance" framework exists).

When is the MPAA triggered?

The MPAA is triggered by any of the following events:

• Taking any taxable income from a flexi-access drawdown arrangement (even a single £1 withdrawal)
• Taking an UFPLS (uncrystallised funds pension lump sum), which is simultaneously partly tax-free and partly taxable
• Reaching a cap in a capped drawdown arrangement and taking excess income (which automatically converts the arrangement to flexi-access)
• Purchasing an annuity with a flexible income feature (a rare product)

Events that do NOT trigger the MPAA include:

• Taking only the pension commencement lump sum (PCLS) and placing the remainder into drawdown without taking any income
• Receiving a lifetime annuity (conventional, non-flexible)
• Reaching age 75 without taking any crystallisation events
• Taking small pots lump sums or trivial commutation lump sums

The part-time retirement scenario

A very common scenario is the individual who "semi-retires" in their late fifties or early sixties by reducing their hours, taking a pension to supplement their reduced salary. This seems financially sensible — use the pension to bridge the income gap — but if the pension is taken from a drawdown arrangement, the MPAA is triggered from the first taxable drawdown payment.

The consequences for employer pension contributions can be severe. If you are still employed and your employer is obliged to enrol you into a workplace pension and contribute to it, those employer contributions count towards the £10,000 MPAA. An employer contributing £8,000 per year and an employee contributing £4,000 per year would together breach the £10,000 MPAA, triggering an annual allowance charge.

Calculating MPAA exposure

The MPAA applies to all pension input amounts to money purchase schemes. This includes:

• Personal contributions you make
• Employer contributions to your workplace scheme
• Contributions made by any third party on your behalf

If the total of all contributions to money purchase schemes exceeds £10,000 in any year after the MPAA is triggered, the excess is subject to an annual allowance charge at your marginal income tax rate. There is no carry forward available to increase the MPAA.

For a part-time employee earning £30,000 and contributing 5% (£1,500) to a workplace pension, with an employer contributing 5% (£1,500), the total pension input is £3,000 — well within the £10,000 MPAA. This employee has triggered the MPAA (by taking drawdown) but has not breached it.

For a senior part-time professional earning £80,000 and contributing 10% (£8,000) with an employer contributing 10% (£8,000), the total of £16,000 exceeds the £10,000 MPAA by £6,000. An annual allowance charge at 40% or 45% would apply on the excess.

Opting out of employer contributions

One practical response for employees who have triggered the MPAA and are at risk of breaching it is to opt out of the workplace pension entirely, or to reduce contribution rates to keep total inputs within £10,000. This is a significant concession — foregoing employer contributions is genuinely costly — but it may be preferable to incurring annual allowance charges.

Before opting out, employees should check the employer's auto-enrolment policy and whether voluntary opt-out is permitted under the scheme rules. In some cases, employers make minimum contributions regardless of employee elections.

Alternative: using a salary sacrifice arrangement carefully

Where the employer offers salary sacrifice as the mechanism for pension contributions, the employee can potentially control the total contribution more precisely by adjusting the sacrifice level. If salary sacrifice is reduced, the employer's national insurance saving (which is sometimes shared as an additional contribution) also adjusts.

This requires active communication with the employer and is not always simple to implement, but for high earners it can be worth the administrative effort.

The DB alternative annual allowance

If you are a member of both a defined benefit (DB) scheme and a money purchase (DC) scheme, and you trigger the MPAA, the position is complicated by the "alternative annual allowance" (AAA) rules.

After the MPAA is triggered, the amount of the standard annual allowance (£60,000) that is not used for money purchase inputs can be applied to DB pension accrual. The AAA is therefore the standard annual allowance minus the MPAA: £60,000 minus £10,000 = £50,000 in 2026–27.

This means that triggering the MPAA does not stop you from accruing DB pension rights up to £50,000 of the capitalised benefit increase per year. However, the total of all inputs (DC within £10,000 and DB within £50,000) cannot exceed the overall annual allowance.

Phased retirement without triggering the MPAA

There is a way to draw partial retirement income from a defined contribution pension without triggering the MPAA: take only tax-free cash (PCLS), leaving the remaining fund in drawdown without taking any income from it. The MPAA is not triggered merely by designating funds into drawdown — it is triggered only when taxable income is drawn from the drawdown pot.

This is the "crystallise and park" approach: you take the 25% tax-free lump sum, invest the remaining 75% in drawdown, and draw nothing taxable from the drawdown fund. Your MPAA protection is preserved. You can then rely on other income sources while retaining the ability to make larger pension contributions.

For individuals who have accumulated substantial pension savings and have other income sources (rental income, ISA withdrawals, state pension), this strategy can be effective. However, it requires sufficient non-pension capital to fund living costs without triggering taxable drawdown income.

UFPLS and the MPAA

Taking an UFPLS — a lump sum directly from an uncrystallised fund, of which 25% is tax-free and 75% is taxable — always triggers the MPAA, even for a small UFPLS. Some individuals mistakenly believe that taking a small UFPLS is "less serious" than entering drawdown, but the MPAA consequence is identical.

Notification obligations

When the MPAA is triggered, the scheme or provider must notify you that the MPAA has been triggered. You are then required to notify any other pension scheme to which you are making contributions, so that those schemes can monitor whether the MPAA is being breached. Failure to notify can result in additional penalties.

Practical planning checklist

Before taking any taxable pension income in retirement or semi-retirement, consider:

1. Will you continue to make or receive pension contributions after commencing drawdown?
2. What is your employer's contribution rate, and will it push you over the £10,000 MPAA?
3. Could you take only the PCLS without any drawdown income, to preserve the full £60,000 allowance?
4. Is a DB alternative annual allowance relevant to your situation?
5. Have you notified all other pension providers of the MPAA trigger?

Seek regulated advice

The interaction of the MPAA with workplace pension obligations, salary sacrifice, DB membership, and phased retirement planning is complex. Annual allowance charges can be substantial. Rules may change in future. This guide provides an overview as of 2026 and does not constitute personal financial advice. Seek regulated advice before taking any drawdown income if you are likely to continue making pension contributions.
