Are UK Pensions Taxable? How Pension Tax Works (2026)

Most UK pension income is taxable. The common belief that a pension is paid tax-free is only partly right: a portion can usually be taken without income tax, but the bulk of what comes out of a pension is treated as income and taxed at your marginal rate. The rules apply to defined contribution pots, personal pensions and SIPPs, and they interact with your other income in the same tax year.

This article explains how pension tax works in practice for the 2025/26 and 2026/27 tax years: the 25% tax-free element and its cap, the marginal-rate tax on the rest, how the personal allowance fits in, and why a first withdrawal often suffers emergency tax that has to be reclaimed.

• Up to 25% of a defined contribution pot can usually be taken free of income tax.
• That tax-free element is capped by the Lump Sum Allowance at £268,275 for most people.
• The remaining 75% is taxed as income at your marginal rate when you draw it.
• The personal allowance (£12,570, frozen to 2030/31) and income tax bands determine how much tax applies.
• A first flexible withdrawal is often taxed using an emergency code, so too much tax can be deducted.
• Overpaid emergency tax is reclaimed from HMRC using form P55, P53Z or P50Z.

The 25% tax-free element and its cap

When you start taking money from a defined contribution pension, you can normally take up to 25% of the pot as a tax-free lump sum. This is the pension commencement lump sum. The current minimum pension age is 55, rising to 57 from April 2028.

The tax-free amount is not unlimited. It is capped by the Lump Sum Allowance (LSA), set at £268,275 for most people. Every time you take a tax-free lump sum, it uses part of that allowance. Once the £268,275 is fully used, any further lump sums are taxed as income. People who hold valid pension protection from earlier regimes may have a higher protected figure. The 25% tax-free position was not changed in the 2025 Autumn Budget.

How the rest is taxed

The portion of the pension that is not tax-free is taxed as income. Whether you take it through drawdown, as ad hoc lump sums (UFPLS), or as an annuity, the taxable part is added to your other income for the year and taxed at your marginal rate. There is no separate, lower pension tax rate. The rate that applies depends on your total taxable income and the income tax bands.

For 2025/26 and 2026/27 the personal allowance is £12,570 and the bands are unchanged. These thresholds are frozen, currently to 2030/31, so more pension income can be drawn into tax over time as other income rises.

Bands differ for Scottish taxpayers, who follow Scottish income tax rates on non-savings income. The personal allowance is also reduced by £1 for every £2 of income above £100,000, so it disappears entirely at £125,140. Drawing a large taxable pension sum in one year can therefore push income into a higher band or erode the allowance.

How the personal allowance interacts with withdrawals

The personal allowance means a person whose only income is a modest pension may pay little or no tax. Someone drawing £12,000 a year of taxable pension income, with no other income, would fall within the allowance and pay nothing. Add the State Pension, employment, rental or other pensions, and the taxable pension stacks on top, so more of it is taxed.

Because the allowance and bands apply to total income, the timing of withdrawals matters. Spreading taxable pension income across several tax years can keep more of it within lower bands than taking a single large sum. Each person's position depends on their full income picture and country of tax residence, since UK tax treatment can differ for those resident abroad.

Emergency tax on the first withdrawal

A first flexible pension withdrawal is frequently overtaxed. Providers often do not hold an up-to-date cumulative tax code, so they apply an emergency code on a non-cumulative (Month 1) basis. HMRC instructs the provider to treat the one-off payment as if the same amount were paid every month for the year, which can deduct tax at higher and additional rates on a single payment.

For example, a one-off £10,000 taxable withdrawal can be taxed as though £120,000 will be received across the year, producing a far larger deduction than the eventual liability. HMRC normally corrects this in time, either automatically or through the year-end reconciliation, but the cash is deducted up front.

To reclaim sooner, three HMRC forms apply, depending on the situation:

• P55 where you have taken only part of the pot and are not emptying it or taking regular payments this tax year.
• P53Z where you have emptied the whole pot and have other taxable income in the year.
• P50Z where you have emptied the whole pot and have no other taxable income in the year.

HMRC aims to process a valid claim and repay any overpayment, typically within about 30 days of the form being received.

Pension tax depends on your total income for the year and your country of tax residence, and the figures here change over time, so confirm your own position against official sources before drawing funds.

FAQ

Are UK pensions taxable?

Most pension income is taxable as income at your marginal rate. The main exception is the tax-free element, usually up to 25% of a defined contribution pot, subject to the Lump Sum Allowance cap of £268,275 for most people.

How much of my pension is tax-free?

Normally up to 25% of a defined contribution pot can be taken free of income tax, capped overall by the Lump Sum Allowance of £268,275. Once that allowance is used up, further lump sums are taxed as income.

What rate of tax applies to pension income?

There is no special pension rate. Taxable pension income is added to your other income and taxed at the standard rates: 0% within the £12,570 personal allowance, then 20%, 40% and 45% as income rises. Scottish taxpayers follow Scottish rates.

Why was my first pension withdrawal taxed so heavily?

Providers often apply an emergency tax code on a Month 1 basis to a first flexible withdrawal, treating the payment as if it repeated every month. This can deduct far more tax than is actually due, which is then reclaimed or reconciled.

How do I claim back overpaid pension tax?

You can reclaim using an HMRC form: P55 if you took only part of the pot, P53Z if you emptied it and have other income, or P50Z if you emptied it and have no other income. HMRC normally repays within about 30 days.
