Pension Tax-Free Cash Explained: Should You Take Your 25%?

When you start accessing a defined contribution pension, you can typically take up to 25% of the pension pot as a lump sum free of income tax. This payment is formally known as the pension commencement lump sum — often abbreviated to PCLS — though it is more commonly referred to as tax-free cash or the 25% tax-free lump sum.

The key feature of the PCLS is that it is paid entirely free of income tax. Unlike pension income taken through drawdown or an annuity — which is taxed at the individual's marginal income tax rate when withdrawn — the PCLS is received with no income tax deducted.

The PCLS applies to defined contribution pensions, including personal pensions, self-invested personal pensions (SIPPs) and most modern workplace money purchase pensions. Defined benefit (final salary) pension schemes also typically allow members to take a cash lump sum, though usually by giving up part of the annual pension income. The rules and amounts for defined benefit schemes differ from defined contribution arrangements.

Our article on How To Take Pension Income In Retirement provides a broader overview of the different ways pension income can be accessed in retirement.

For most people, the tax-free cash entitlement is 25% of each pension pot that is crystallised — that is, brought into payment. However, there is a cap on the total amount of tax-free cash that can be taken across all pension arrangements combined over a lifetime.

Since the abolition of the Lifetime Allowance in April 2024, the relevant limit is the Lump Sum Allowance (LSA). The Lump Sum Allowance caps the total tax-free cash that can be taken across all registered pension schemes over a lifetime at £268,275 for most people.

This figure represents 25% of the previous Lifetime Allowance of £1,073,100, and has been set at that level following the LTA abolition. Pension savings above this level can still be taken as a cash lump sum, but any amount above £268,275 would be subject to income tax at the individual's marginal rate rather than being tax-free.

Some individuals hold enhanced protection, fixed protection, or individual protection from previous Lifetime Allowance regimes, which may give them a higher tax-free cash entitlement than the standard £268,275. These protections were granted by HMRC in specific circumstances. Individuals with such protections should confirm their position before accessing pension benefits.

Tax-free cash from a defined contribution pension can currently be taken from age 55. This is the normal minimum pension age.

The normal minimum pension age is increasing from 55 to 57 in April 2028. Most individuals without existing scheme protections will need to wait until age 57 from that point. Some individuals with certain protected pension ages under existing scheme rules may retain the right to access pensions at an earlier age — this is a complex area and worth checking with the individual pension scheme.

There is no requirement to take tax-free cash at a particular time once minimum pension age is reached. It can be taken at the start of accessing pension benefits, in stages over time, or not at all. You do not have to take tax-free cash simply because you are entitled to it — it is an option, not an obligation.

When tax-free cash is taken from a pension pot, the remaining 75% of that pot becomes crystallised — meaning it has been designated for pension benefit purposes. This remaining crystallised pot is not tax-free and will be subject to income tax when it is eventually withdrawn.

The crystallised pot can be used in a number of ways:

• Moved into a flexi-access drawdown arrangement, where it remains invested and income can be withdrawn flexibly — taxed at the individual's marginal income tax rate when taken out
• Used to purchase an annuity, which provides a guaranteed income for life in exchange for the pension capital
• A combination of the two — for example, using part of the remaining pot to buy an annuity to cover fixed expenses and keeping the rest in drawdown for flexible access

Our article on Pension Drawdown Explained covers how flexi-access drawdown works in more detail.

Taking tax-free cash and designating the remaining 75% to a drawdown fund does not mean income must be drawn from the fund immediately. The crystallised pot can remain invested within the drawdown arrangement, with income drawn at a time and level of the individual's choosing.

Our article on How Pension Withdrawals Are Taxed in the UK explains how taxable drawdown withdrawals are treated for income tax purposes.

It is not necessary to take the entire pension pot's 25% tax-free cash entitlement all at once. Most modern defined contribution pension platforms allow tax-free cash to be taken in stages — a process often called phased retirement or partial crystallisation.

Under a phased approach, a portion of the pension pot is crystallised at a time. Each time a segment is crystallised, 25% of that segment is taken as tax-free cash and the remaining 75% moves into a drawdown fund. Further portions of the uncrystallised pot can then be crystallised in the same way at a later date.

This approach can help manage income tax exposure. Taking the full 25% tax-free cash from a large pension pot in a single tax year could mean receiving a substantial lump sum alongside other income, potentially pushing taxable income into a higher tax band for that year. A phased approach allows tax-free cash to be released gradually in amounts that work more efficiently within the individual's overall income and tax position each year.

Not all pension providers support phased drawdown. If this approach is being considered, it is worth confirming with the pension provider that it is available on the specific platform before any decisions are made.

The decision of whether to take pension tax-free cash — and when — involves a range of personal considerations. The following are among the factors that often feature in these decisions:

Income tax position

Because the PCLS is tax-free, taking it can be more income-tax-efficient than drawing the same amount as taxable income from drawdown. However, the overall benefit depends on the individual's marginal tax rate, other income sources and how the lump sum would be used or invested. Taking a large tax-free lump sum in the same tax year as other significant income requires careful consideration.

Income needs in retirement

Whether the tax-free cash is needed to fund a specific immediate cost — such as clearing a remaining mortgage balance, paying for home adaptations or covering a significant planned expenditure — or is simply being taken because it is available affects how the decision should be weighed.

Estate planning considerations

The 2027 changes to pension inheritance tax — explained in our article on Pensions and Inheritance Tax: What the 2027 Changes Mean for You — alter how unused pension pots are treated on death. Before 2027, leaving a pension pot intact was a specific estate planning choice because pensions sat outside the estate for inheritance tax purposes. From 2027, pension pots will count towards the estate for inheritance tax alongside other assets. Whether and how this affects the decision to take tax-free cash depends on individual circumstances and should not be assumed to point in a single direction.

Effect on future pension contributions

Taking income flexibly from a pension — through flexi-access drawdown or an uncrystallised funds pension lump sum (UFPLS) — triggers the Money Purchase Annual Allowance (MPAA). For 2026/27, the MPAA is £10,000. Once triggered, future defined contribution pension contributions (from any source, including employer contributions) are capped at this lower annual allowance rather than the standard £60,000 annual allowance.

Taking the tax-free cash alone and moving the remaining 75% into a drawdown fund, without drawing any taxable income from that fund, does not in itself trigger the MPAA. The MPAA is triggered only when flexible income is first taken. Individuals who are still working and building pension savings should understand this distinction carefully before taking any pension benefits.

Pension pot size and the Lump Sum Allowance

For individuals with large pension pots, the 25% tax-free cash on the full pot may exceed the £268,275 Lump Sum Allowance cap. Any amount above that figure would not be tax-free — it would be subject to income tax at the marginal rate. This is particularly relevant for those with multiple pension arrangements or very large pots.
