Your details

£

The current value of the defined contribution pot you are withdrawing from. Defined benefit (final salary) schemes work differently — their lump sum is set by scheme commutation factors.

£

The total amount you plan to withdraw in the 2026/27 tax year. Capped at the pot value in the calculation.

A UFPLS pays 25% of each withdrawal tax-free and taxes the rest. A PCLS takes the tax-free cash up front (moving the balance into drawdown). Withdrawals from funds already in drawdown are fully taxable.

£

Tax-free cash you have taken from any pension since it counts against your £268,275 lump sum allowance. Once the allowance is used up, further 'tax-free' cash is taxed at your marginal rate.

£

Salary, self-employment profit, state and other pensions, rent and interest. The taxable part of your lump sum stacks on top of this, which decides how much falls into the 40% and 45% bands.

Without a current-year tax code, providers must apply an emergency code on a Month 1 basis, which usually over-taxes single large withdrawals. The overpayment is reclaimable in-year via forms P55, P53Z or P50Z.

Frequently asked questions

How much tax will I pay on my pension lump sum?

Usually nothing on the first 25% and income tax at your marginal rate on the rest. The taxable balance is added to your other income for the year and taxed at 2026/27 rates — 20%, 40% and 45% — so a large single withdrawal can push you several bands higher than your normal salary would. For example, taking £100,000 as a UFPLS with £30,000 of other income gives £25,000 tax-free and roughly £26,900 of tax on the £75,000 taxable slice, an effective rate of about 27% on the whole withdrawal.

Is 25% of my pension always tax-free?

Up to a limit. You can normally take 25% of each pension tax-free, but the tax-free total across all your pensions is capped by the lump sum allowance of £268,275 — 25% of the old £1,073,100 lifetime allowance. If your combined pots exceed about £1.07 million, some of your '25%' will be taxable. People who held lifetime allowance protections may have a higher personal cap.

What is the lump sum allowance (LSA)?

The £268,275 lifetime cap on tax-free lump sums, introduced on 6 April 2024 when the lifetime allowance was abolished. Every tax-free lump sum you take — PCLS or the tax-free quarter of a UFPLS — uses part of it. Once it is exhausted, further lump sums are taxed in full at your marginal rate. A separate £1,073,100 lump sum and death benefit allowance applies to serious ill-health and death benefit payments.

Why was my pension withdrawal taxed so heavily?

Almost certainly emergency tax. On a first withdrawal, your provider usually has no current-year tax code for you and must apply an emergency code on a Month 1 basis — treating the payment as if it were one month of a regular salary, with just £1,047.50 of tax-free allowance and one-twelfth of each tax band. A £75,000 taxable payment attracts around £32,000 of emergency deduction even when the correct annual tax is far lower. The overpayment is refundable.

How do I claim back emergency tax on a pension lump sum?

File the right HMRC form for your situation: P55 if you have taken part of the pot and are not taking regular income, P53Z if you emptied the pot and have other income, or P50Z if you emptied the pot and have no other income. HMRC typically repays within about 30 days of an in-year claim. If you do nothing, HMRC's end-of-year reconciliation should still refund you automatically — but that can mean waiting more than a year for your money.

Can I avoid emergency tax on my first withdrawal?

Largely, yes. Taking a small first withdrawal — even £100 — forces the provider to obtain a current tax code from HMRC, so the main withdrawal that follows is taxed correctly. Spreading a large withdrawal across two or more payments, or across two tax years, has the same effect and often reduces the actual tax as well by keeping the taxable slices in lower bands.

Does a pension lump sum push me into a higher tax band?

The taxable part does. It stacks on top of your other income, so it can move you from 20% into 40%, past £100,000 where the personal allowance tapers away at £1 for every £2 (an effective 60% band to £125,140), and into 45% above that. This is why the same total withdrawn over three tax years often costs dramatically less tax than one big withdrawal — the calculator's year-by-year comparison is worth running before you sign anything.

What is the difference between UFPLS and drawdown tax-free cash?

A UFPLS (uncrystallised funds pension lump sum) takes money straight from the untouched pot: 25% of each payment is tax-free and 75% taxable. A PCLS (pension commencement lump sum) takes the whole 25% tax-free amount up front and moves the remaining 75% into drawdown, where later withdrawals are fully taxable. The tax over a lifetime can be identical — the difference is timing, flexibility and, for higher-rate planning, which years the taxable income lands in.

At what age can I take a lump sum from my pension?

From the normal minimum pension age — currently 55, rising to 57 on 6 April 2028 — unless you are in serious ill health or have a protected earlier age. Anyone born after 5 April 1973 should plan around age 57. Accessing a pension earlier through unregulated 'pension liberation' schemes triggers unauthorised payment charges of up to 55% plus scheme sanction charges, and is one of HMRC's most heavily policed areas.

Does taking a lump sum trigger the £10,000 money purchase annual allowance?

Taking taxable money flexibly does. A UFPLS or any taxable drawdown income triggers the money purchase annual allowance, cutting future tax-relieved pension contributions from £60,000 to £10,000 a year permanently. Taking only tax-free cash (a PCLS) without any taxable withdrawal does not trigger it. Anyone still contributing — or whose employer contributes — should sequence withdrawals to preserve the full annual allowance as long as possible.

How is a UK pension lump sum taxed if I am a US citizen?

Painfully, if unplanned. The UK's 25% tax-free lump sum is not automatically tax-free in the United States: under the US-UK treaty's saving clause the US generally retains the right to tax its citizens' pension lump sums, so the 'tax-free' cash can be fully taxable on Form 1040 — with no UK tax paid on it to credit. Periodic withdrawals, by contrast, are taxed by the UK first with a US foreign tax credit. The gap between a planned and unplanned withdrawal for a dual filer can run to tens of thousands of dollars, which is exactly the modelling a cross-border adviser should do before you touch the pot.

Do I pay National Insurance on pension withdrawals?

No. Pension income and lump sums are free of National Insurance regardless of your age or the size of the withdrawal — only income tax applies. This makes pension withdrawals cheaper than salary for the same gross amount, and it is one reason salary sacrifice into a pension and later withdrawal is such an efficient loop for higher earners.

Will my pension lump sum affect inheritance tax?

Increasingly, yes. From 6 April 2027 unused pension funds and death benefits are due to come within the scope of inheritance tax, removing the long-standing advantage of leaving the pension untouched until last. Money withdrawn and not spent also sits in your estate. The right order of withdrawals — pension versus ISA versus taxable accounts — is being rewritten by this change, and anyone with an estate near the nil-rate bands should revisit their drawdown plan before April 2027.

Can I take 25% tax-free from each of my pensions separately?

Yes. Each registered pension can pay its own 25% tax-free lump sum, at times you choose, as long as your total tax-free cash stays within the £268,275 lump sum allowance. Staggering different pots across years is a core planning technique: it lets you fill lower tax bands with the taxable portions year by year rather than stacking everything into one band-busting payment.
