Why cashing out your pension in full could be a costly mistake

In 2015, the pension freedoms came in, and pension savers were told they could do whatever they liked with their pot. This was a real change, but you should think carefully before cashing out your pension in one go.

People no longer had to buy an annuity, and could instead leave their pension invested and draw from it, effectively turning the pension into a bank account. The pensions minister at the time even joked that people could go and blow it on a Lamborghini.

The reality is more complicated. If you cash out your pension, you get the first 25% as tax-free cash, but HMRC counts everything else you draw as income and taxes it accordingly. 

A pension is not just a savings account. It is a tax efficient pot built up over decades, and cashing it out in one go can undo years of planning in a single afternoon.

Cashing out your pension: the tax-free cash trap

Most people know the first 25% of a pension comes out tax-free. Fewer people realise everything above that is taxed as income in the year you take it.

Take a pension pot worth £64,000. The first £16,000 is tax-free, but should you take the remaining £48,000, that would be added to your income for that year.

It’s very unlikely a financial advisor would recommend cashing out your pension in full in one tax year. Spreading the withdrawal across multiple years usually keeps more of the income within lower tax bands, avoiding an unnecessary higher rate tax charge.

How the £48,000 is taken	Taxable pension income each year	Income tax each year	Total income tax
All in one tax year	£48,000	£7,086	£7,086
Spread over three tax years	£16,000	£686	£2,058

 

Based on 2025/26 rates, with no other taxable income and the standard £12,570 personal allowance. Taking the money over three years rather than one saves just over £5,000 in tax on the same pot.

If a large withdrawal pushes you into a higher tax band, you could pay a significant amount directly to HMRC. A single large withdrawal can push someone from basic rate into higher rate tax for that year alone.

This means the tax paid on the withdrawal can be far higher than expected. A pot that looked like £64,000 on paper can shrink considerably once the tax bill lands.

Running out of money later

There is also the question of running out of money later. When you are cashing out your pension, it is important to consider how much income you will need throughout retirement. Once a pension is cashed out and spent, there is no fallback income in retirement.

State pension alone is rarely enough to live on comfortably. Most people need a private pension, savings, or other income to maintain their standard of living once they stop working.

Better ways to reach the same goal

Some people consider cashing out their pension because they worry about pension rules changing, or because they want to clear debt quickly. Both are understandable concerns, but rarely require cashing out the whole pot.

Usually there are less costly ways to reach the same goal, such as drawdown, part withdrawals, or debt consolidation advice. A regulated advisor can usually find a route that avoids an unnecessary tax bill.

Means tested benefits

There are also means tested benefits to consider before cashing out your pension. A large lump sum in a bank account can affect entitlement to certain benefits in a way that untouched pension savings would not.

People often overlook this issue until it is too late. By the time a benefit review happens, the authorities may already count the lump sum as savings.

A decision to cash out can also affect divorce settlements, inheritance planning and future care costs. The rules treat pension savings differently from cash savings in several of these situations.

Watch out for the money purchase annual allowance

Another point to consider when cashing out your pension is the money purchase annual allowance. Taking taxable income from a pension can trigger a lower annual allowance for future contributions.

This can catch out people who cash out early in retirement and then return to work later. Once you trigger it, the lower allowance stays in place and limits how much you can contribute tax efficiently in the future.

Why timing matters

Timing also matters when you are considering cashing out your pension or taking money from it gradually. Withdrawing in one tax year rather than spreading across two or three can be the difference between paying basic rate and higher rate tax on a large portion of the pot.

Spreading withdrawals across several tax years, where possible, keeps more of each year’s income within the lower tax bands. This alone can save a meaningful amount of tax over time, without reducing the total amount eventually received.

You should also check whether your pension has any exit fees or guarantees before you move or cash it in. Losing a valuable guarantee by accident is a common and costly mistake.
