In 2015, the pension freedoms came in, giving savers more choice over their pensions. But cashing out your pension in full can create significant tax and retirement planning issues.
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 receive the first 25% as tax-free cash. HMRC treats 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. Cashing out your pension can undo years of planning in a single afternoon.

Summary: Why cashing out your pension in full could be a costly mistake
- Since the 2015 pension freedoms, savers can cash in their whole pension, but only the first 25% is tax-free. The remaining 75% counts as income in the year it is taken, so one large withdrawal can push you into a higher tax band and shrink the pot considerably.
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 the entire £64,000 in one tax year. Spreading the withdrawal across multiple years usually keeps more income within lower tax bands. This can help you avoid an unnecessary higher rate tax charge.
If that pushes you into a higher tax band, a large chunk goes straight 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.
Cashing out your pension and running out of money later
There is also the question of running out of money later. 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.
Case study
A client aged 61 held two personal pensions worth £32,000 each. He wanted to discuss his income options and whether consolidating both pots into one plan made sense. He also wanted to understand the tax implications of taking more than 25% as tax-free cash.
After a full review, his advisor explained that consolidating the two pensions into one plan would simplify charges and make income planning easier going forward. They also worked through an income drawdown plan that let him access tax-free cash gradually rather than all at once. This approach avoided a large one off tax bill in a single year, and kept the remaining pot invested for continued growth. It also meant he still had savings within the pension wrapper for later in retirement, rather than a smaller amount sitting in a bank account. A financial advisor can also look at the wider picture. This includes other savings, any workplace pensions, and how state pension will fit in later. Getting this right early can make a real difference. Small decisions now, like how and when money comes out of a pension, can add up to a large difference in tax paid over a lifetime. Before taking your pension as a lump sum, it is worth speaking to a regulated financial advisor. A short conversation now could save you thousands in unnecessary tax later, and help you keep your options open for the years ahead.
Better ways to reach the same goal
Some people cash out 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. A large lump sum in a bank account can affect entitlement to certain benefits in a way that untouched pension savings would not.
This is often overlooked until it is too late. By the time a benefit review happens, the lump sum has already been counted as savings.
Divorce settlements, inheritance planning, and future care costs can all be affected by a decision to cash out too. The rules treat pension savings differently from cash savings in several of these situations.
Watch out for the money purchase annual allowance
Another point worth considering 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. This limits how much you can pay into your pension tax efficiently in future.
Speak to a financial advisor

Find a financial advisorWhy timing matters
Timing also matters when deciding how to take money from a pension. 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 moving or cashing it in. Losing a valuable guarantee by accident is a common and costly mistake.
