The 25% Tax-Free Pension Lump Sum, Explained

By Sam Parkinson · Last updated: July 2026 · 7 min read

One of the most appealing features of a UK pension is that you can normally take a quarter of it completely tax-free. There are rules on how much, when, and how it works, and a couple of tax traps that catch people out. Here's the plain-English version.

What is the 25% tax-free lump sum?

When you reach the age you're allowed to touch your pension, you can usually take up to 25% of your pension pot as a tax-free lump sum. The other 75% stays available to give you an income, and that part is taxed as normal income when you draw it.

In the jargon this tax-free amount is called the pension commencement lump sum, or PCLS, but most people just call it their tax-free cash. It applies to defined contribution pensions, the type most people build up at work today. Older defined benefit or final salary pensions can work differently, often paying a smaller tax-free lump sum in exchange for giving up some guaranteed income, so if that's what you have, check your scheme's own figures.

When can you take it?

You can currently take your tax-free cash from age 55. This is rising to 57 from 6 April 2028, which affects anyone born after 6 April 1971, so if you're planning around a particular birthday, check which side of that change you fall on. Our guide to the rising pension age goes into who is affected.

You don't have to take the cash the moment you qualify, and there are often good reasons to wait. Leaving your pot invested gives it more time to grow, and the 25% is worked out on the pot's value at the time you take it, so a bigger pot later means more tax-free cash.

How much could you get? A worked example

You don't have to take the full 25% in one go. How you take it changes the tax you pay, so it's worth knowing the two main routes.

Two ways to take your tax-free cash

Most defined contribution pensions let you choose how to draw the money:

• Take the tax-free cash up front, then draw income later. You move your pot into drawdown, take some or all of your 25% as a lump sum, and leave the rest invested to draw a taxable income when you need it. This is the most common approach.
• Take it in slices (UFPLS). With an uncrystallised funds pension lump sum, each withdrawal is 25% tax-free and 75% taxable. So a £10,000 withdrawal gives you £2,500 tax-free and £7,500 taxed as income. Spreading withdrawals across tax years can keep more of the taxable part in lower bands.

Which suits you depends on whether you want a big lump now or a steady drip, and on your wider income. This is a common thing to model with a regulated adviser before you commit, because the choice is hard to unwind.

The £268,275 cap

There's an upper limit. The most tax-free cash you can take across all your pensions is £268,275, known as the lump sum allowance. It's 25% of the old £1,073,100 lifetime allowance, now frozen as a standalone figure. If your pensions are large enough that 25% would exceed this, the amount above the cap isn't tax-free.

For most people the cap sits comfortably above what they'll build up. It matters mainly if you're a higher earner with a substantial pot, or you have several pensions that add up to more than about a million pounds between them.

Mind the tax on the other 75%

The tax-free part is the easy bit. The 75% behind it is taxable, and two things catch people out. First, taking a large taxable amount in a single tax year can push you into a higher tax band, so a big withdrawal can be taxed more heavily than the same amount spread over two or three years. Second, the first flexible withdrawal is often taxed on an emergency code, which can overcharge you upfront. You get it back, either automatically or by reclaiming from HMRC, but it's a nasty surprise if you weren't expecting it.

Should you take the tax-free cash?

Just because you can take 25% tax-free doesn't mean you should take it all at once. A few things worth weighing:

• Money left invested keeps working. Pull a big lump out and it stops benefiting from any growth inside the pension, and it's no longer in the tax-friendly pension wrapper.
• A clear purpose beats a vague one. Clearing a mortgage, paying off expensive debt, or bridging the years before the State Pension starts are solid reasons. Taking it just to shift it into a savings account, where the interest is taxable, often isn't.
• Think about what you leave behind. With the 2027 inheritance tax change coming, the old logic of leaving a pension untouched to pass on is shifting. This is exactly the kind of decision worth advice on.

Common questions

The bottom line

The 25% tax-free lump sum is one of the most valuable perks of pension saving. You can take up to a quarter of your pot tax-free from age 55 (57 from 6 April 2028), up to a cap of £268,275. The headline is simple, but how and when you take it, and the tax on the rest, have real consequences. For anything significant, get proper advice before you act.
