Crystallising a pension pot in the UK means accessing your pension savings (or designating them for access), usually after the age of 55 (rising to 57 in April 2028). It’s a technical step that triggers certain tax rules and benefit options. NMTBP explains how it works and the pros/cons

You generally crystallise your pension by:

1. Contacting your pension provider – and telling them how you want to access your savings

2. Choosing an option (or mix of options):

   • Flexi-Access drawdown: Move your funds into a drawdown account, take up to 25% tax-free lump sum, then withdraw income as needed (taxed as income)

   • Uncrystallised Funds Pension Lump Sum (UFPLS): Take lump sums directly from your pot, each withdrawal giving you 25% tax-free and 75% taxable

   • Annuity purchase: Use the fund to buy a guaranteed income for life; typically, 25% can be taken tax-free upfront

   • Partial Crystallisation: You don’t have to do it all at once – you can crystallise portions of your pot over time

✅ The advantages of crystallising

• Tax-free cash (PCLS): You can take up to 25% of your pot tax-free (subject to limits)

• Flexibility: With drawdown, you keep your money invested and can control how much income you take

• Phased crystallisation: This lets you manage tax by taking benefits gradually, rather than in one lump sum

• Inheritance planning: Crystallised funds left in drawdown can usually be passed on tax-efficiently (often free of inheritance tax, and sometimes income tax-free if death occurs before age 75). This is scheduled to change in 2026

• Control over timing: Crystallising allows you to align withdrawals with other income, potentially keeping yourself in a lower tax band

⚠️ Considerations / Downsides

• Triggers the Money Purchase Annual Allowance (MPAA): If you take taxable income (not just the 25% tax-free lump sum), your future pension contributions limit usually drops from £60k to £10k per year

• Income tax risk: Withdrawals beyond the 25% tax-free portion are taxed as income, which could push you into a higher tax band

• Investment risk: If you opt for drawdown, your pot remains invested and may decrease in value

• Loss of growth: Taking lump sums early means less invested for future retirement needs

• Annuity rates: If you buy an annuity at the wrong time (e.g., during periods of low interest rates), you may lock into poor returns

In short:

• You crystallise by telling your provider how you want to take benefits

• The big attraction is accessing 25% tax-free and creating flexible income options

• The downsides are mainly tax, reduced pension contribution allowances, and investment risk

As always, make sure you take professional advice before acting, and caveat emptor
