How UK Pensions Are Taxed in Retirement: A Complete Guide

The most widely understood feature of UK pension taxation is the availability of a tax-free lump sum — often called "tax-free cash" — when benefits are first accessed. In technical terms, this is now called the Pension Commencement Lump Sum (PCLS).

The PCLS Limit

When the Lifetime Allowance was abolished from 6 April 2024, the maximum PCLS was capped at £268,275 — equivalent to 25% of the old standard Lifetime Allowance of £1,073,100. For most pension savers, this means 25% of their pension fund is tax-free, up to the maximum.

For a pension fund of:

• £200,000: PCLS = £50,000 (25%)
• £500,000: PCLS = £125,000 (25%)
• £1,000,000: PCLS = £250,000 (25%)
• £1,500,000: PCLS = £268,275 (capped — only 17.9% of the fund, not 25%)

Those with Higher PCLS Entitlement

Those who held valid protection certificates before April 2024 — Enhanced Protection, Fixed Protection 2012, Fixed Protection 2014, Fixed Protection 2016, Individual Protection 2014, or Individual Protection 2016 — may have a higher PCLS entitlement. The transition rules introduced alongside the LTA abolition preserved the higher PCLS for those with valid protection, up to 25% of the protected amount.

If you hold a protection certificate, do not assume the £268,275 cap applies to you — seek specialist advice on your specific entitlement.

Taking PCLS in Stages

A common misconception is that you must take all your tax-free cash at once when you first access your pension. In fact, you can phase your crystallisation — designating portions of the pension to drawdown over time, taking 25% of each designated tranche tax-free.

Example: A pension pot of £600,000 could be designated in three tranches over three years:

• Year 1: Designate £200,000 to drawdown; take £50,000 PCLS tax-free, £150,000 goes to drawdown
• Year 2: Designate another £200,000; take £50,000 PCLS, £150,000 to drawdown
• Year 3: Final £200,000; take £50,000 PCLS, £150,000 to drawdown

Total PCLS taken: £150,000 tax-free over three years. Total drawn to drawdown: £450,000.

This phased approach is particularly useful where: (a) you do not need a large lump sum immediately; (b) spreading tax-free cash across tax years is more efficient; or (c) you wish to delay triggering drawdown income until needed.

The personal allowance (£12,570 in 2026/27, frozen until at least April 2031) is available to UK residents automatically. For non-UK residents, it depends on the terms of the relevant double taxation treaty:

• EEA residents: the UK personal allowance is generally available under EU/EEA agreements that the UK has preserved post-Brexit in most cases, but check the specific position.
• Non-EEA treaty countries: some DTTs allow non-residents to claim the personal allowance, others do not.
• Countries without a DTT with the UK: non-residents have no personal allowance.

For expats drawing pension income, the availability or otherwise of the personal allowance makes a significant difference to the annual tax-free amount they can draw without UK income tax.

The Personal Allowance Trap at £100,000

For those with total income above £100,000, the personal allowance is reduced by £1 for every £2 of income above £100,000, creating an effective marginal tax rate of 60% on income between £100,000 and £125,140 (in England). A retired person drawing large amounts of pension income who tips into this band is paying 60p in tax for every additional pound of income.

Avoiding this trap by limiting annual pension withdrawals to below £100,000 — and drawing the remainder in a subsequent tax year — can save very significant sums.

Annuity income is taxed in the same way as drawdown income — as pension income at marginal rates. There is no tax advantage to an annuity over drawdown (or vice versa) purely in terms of income taxation. The difference lies in certainty, flexibility, and longevity insurance — not in tax treatment.

On death, pension funds held in drawdown (or uncrystallised) are generally not subject to income tax if the member dies before age 75. Beneficiaries can draw the inherited fund tax-free.

If the member dies on or after age 75, beneficiaries pay income tax at their marginal rate on withdrawals from the inherited fund — but there is no immediate tax charge on death itself.

Note that from April 2027, unspent pension funds will be included in the member's estate for Inheritance Tax purposes. This is a significant change — see our separate guide on pension IHT changes for detail.

Global Investments advises clients on pension income strategy throughout retirement — including phased crystallisation, tax-efficient withdrawal rates, and coordination with state pension, annuity, and other income sources. For internationally mobile clients, we also address double taxation treaty implications on pension income and personal allowance entitlement.

Ensuring that pension income is drawn as tax-efficiently as possible over a 20 to 30 year retirement is one of the most valuable services a specialist pension adviser can provide. The decisions made in the early years of retirement have a compounding impact that is not easily reversed.
