Taking your 25% tax-free cash: why timing matters

Most people can take around a quarter of a defined contribution pension free of income tax from the normal minimum pension age, subject to an overall cap on tax-free lump sums. It is the best-known feature of the pension system and the one most often used badly — not because people take it, but because of when and how.

It is not a deadline

The most common misunderstanding is that the tax-free entitlement expires, or must be claimed at a particular age. It does not. There is no point at which the right disappears because you did not use it, and no advantage in taking it simply because you have reached the age at which you could.

Money left inside a pension remains in one of the most tax-efficient wrappers available. It grows free of UK income and capital gains tax, and under current rules it generally sits outside your estate for inheritance tax — a position that has been subject to announced change, so it is worth confirming the current treatment before relying on it.

What happens when the cash comes out

The moment a lump sum lands in your current account, its treatment changes completely. Interest becomes taxable above your allowances. The money forms part of your estate. And if it sits in cash for years, inflation erodes it in a way it would not have done inside a diversified pension.

That is fine if you have a use for it. Clearing a mortgage, funding a specific project, or bridging the years between stopping work and the State Pension starting are all sound reasons. Taking it because you can, and then leaving it in a savings account, is usually a step backwards.

You can take it in slices

You do not have to take the whole entitlement at once. Most modern pensions allow you to crystallise part of the pot at a time, taking a quarter of each slice tax free and leaving the rest untouched and invested.

Taken in pieces, this gives you a tax-free element each year, keeps the bulk of the fund growing, and — used carefully — can keep your taxable income inside a lower band. Combining a tax-free element with a modest taxable withdrawal is how many people fund the early years of retirement at a very low effective rate of tax.

The contribution trap

This one catches people out more than any other. Taking only tax-free cash generally leaves your ability to contribute intact. But taking taxable income flexibly from a defined contribution pension triggers a much lower annual allowance on future contributions — a restriction that is permanent and cannot be undone.

If you are still working, still contributing, or might return to work, this matters enormously. People who take a flexible income at 57 to top up a reduced working pattern sometimes discover years later that they capped their own ability to rebuild the pot.

Order of withdrawals

Which pot you draw on first can make a substantial difference over a long retirement. There is no universal answer, but the questions are consistent:

• Do you have ISA or general investment money that could be used first, leaving the pension to grow?
• Are you in a lower tax band this year than you expect to be later — or the reverse?
• Will the State Pension push you into a higher band when it starts?
• What is the estate position, and how does that interact with the current inheritance rules?

A short period of lower income — for example between stopping work and the State Pension starting — is often the single best window for drawing taxable income cheaply. Missing that window and then drawing heavily once the State Pension is in payment is a common and avoidable inefficiency.

Emergency tax on the first payment

First withdrawals are frequently taxed on an emergency basis, which can deduct far more than is actually owed. It is reclaimable, either through a form or at the end of the tax year, but it is a cashflow shock if you were relying on the money arriving in full. If a payment is timed to meet a specific bill, allow for it.
