Phased Retirement: Using Flexible Drawdown to Ease Into Retirement (2026/27)

What phased retirement actually means

Rather than picking a single retirement date and converting the entire pension pot into drawdown or an annuity on that day, phased retirement takes a more gradual approach: crystallising (accessing) only part of the pension pot at a time, drawing tax-free cash and, if needed, some taxable income from that portion, while leaving the rest of the pot fully invested and untouched.

This approach is particularly well suited to people who are reducing their working hours gradually — moving from full-time to part-time work, taking on consultancy work, or stepping down to a less demanding role — rather than stopping work on a single fixed date.

Why spreading the tax-free lump sum matters

A pension pot's 25% tax-free entitlement (up to the Lump Sum Allowance of £268,275) does not have to be taken all at once. By crystallising the pot in smaller tranches over several years, you access 25% of each tranche tax-free as you go, rather than taking one large lump sum upfront that you may not actually need in full immediately.

This matters for two reasons:

1. Tax efficiency: taking only the income you need each year, rather than a large one-off sum, helps keep your taxable income within a lower tax band, avoiding unnecessary higher-rate tax on withdrawals you did not actually need that year.
2. Investment flexibility: money left uncrystallised remains invested and can continue growing, rather than being moved into cash or a drawdown account before you actually need to spend it.

Worked example: topping up reduced hours

Suppose someone earning £45,000 a year reduces to a three-day week, cutting their salary to £27,000. To maintain something close to their previous total income, they might crystallise a small portion of their pension pot each year, taking:

• The 25% tax-free element of that portion, plus
• A modest amount of taxable drawdown income to bring their total annual income closer to their previous level, while remaining mindful of their new lower tax band position.

Because their earned income has fallen to £27,000, well within the basic-rate band, any modest additional pension income drawn is also likely to be taxed at the basic rate (20%) rather than pushing them into the higher-rate band — a more efficient outcome than fully crystallising the whole pot and potentially creating a large one-off taxable withdrawal in a single tax year.

The Money Purchase Annual Allowance trigger

A key planning point: taking only the tax-free cash from a crystallised portion, without drawing any taxable income at all, does not trigger the Money Purchase Annual Allowance (MPAA). This allows someone to access some tax-free cash while still being able to make full Annual Allowance pension contributions (up to £60,000, or less if tapered for very high earners) if they wish to continue building up their pension from ongoing earnings.

However, as soon as any taxable income is drawn from a drawdown fund, the MPAA is triggered, restricting further tax-relieved contributions to that money purchase pension to just £10,000 a year from that point onwards — a restriction that generally continues indefinitely once triggered, even if withdrawals stop later. Anyone phasing into retirement while still wanting to make significant pension contributions should plan the order and timing of tax-free versus taxable withdrawals carefully.

Practical steps for planning a phased approach

1. Estimate the income gap between your reducing earned income and your desired total income at each stage of the phase-down.
2. Crystallise only the portion of your pension pot needed to cover that gap for the coming year or two, rather than the whole pot.
3. Take tax-free cash first where possible, deferring taxable withdrawals (and the MPAA trigger) for as long as it remains compatible with your income needs.
4. Review the plan annually, since tax bands, allowances and your own earned income are likely to keep changing throughout the phased period.
