## Quick answer

Crystallisation is moving part or all of your pension into a drawdown or annuity arrangement. You can usually take 25% tax-free; the rest is taxed when withdrawn. Phased crystallisation spreads tax-free cash across years.

Before taking income from a defined contribution pension, you crystallise part of the pot. How you crystallise — all at once or in tranches — affects tax, the Money Purchase Annual Allowance and how long your investments stay in the tax wrapper.

## Key facts

- Up to 25% of each crystallised amount can be taken tax-free
- Uncrystallised funds remain invested with no mandatory withdrawals until age 75
- UFPLS lets you take lump sums with 25% tax-free and 75% taxable per withdrawal
- Crystallising for flexible drawdown triggers MPAA if you take taxable income

## Lump sum vs phased

Taking all tax-free cash at once is simple but may waste personal allowance in later years if you do not need the cash immediately.

Phased crystallisation — moving slices of the pot over several years — spreads tax-free cash and taxable withdrawals across tax bands.

## UFPLS

Uncrystallised Funds Pension Lump Sum (UFPLS) takes ad hoc amounts without moving into a formal drawdown plan. Each withdrawal is 25% tax-free and 75% taxable.

UFPLS suits small one-off needs but can trigger MPAA once taxable amounts are taken flexibly.

## What stays uncrystallised

You do not have to crystallise your entire pot at retirement. Leaving funds uncrystallised keeps them growing tax-free and can pass more efficiently to beneficiaries on death before 75.

April 2027 IHT changes may bring unused pensions into estates — see our pension IHT guide.

## Frequently asked questions

### How much tax-free cash can I take?

Broadly 25% of your pension pot subject to the lump sum allowance — check gov.uk if you have lifetime allowance protection or very large pots.

### Can I take tax-free cash without starting drawdown?

Yes — you can take tax-free cash and leave the rest uncrystallised, or use UFPLS for partial access.

### Does crystallisation affect State Pension?

No. State Pension is separate from private pension crystallisation.
