Most people in the UK can usually take 25% of your pension tax-free.  What often comes as a nasty surprise is what happens next. Take too much too quickly, and you can find yourself pushed into a higher tax band—sometimes before you’ve even booked that long-awaited retirement holiday.

The truth is, pensions aren’t completely tax-free. You get tax relief when you pay money in, your investments grow in a tax-sheltered environment, but withdrawals are taxed as income. And from April 2027, any pension you haven’t used could also form part of your estate for inheritance tax.

Are pension plans taxed in the UK?

Yes—but probably not in the way you expect.

There are four key points where tax comes into play:

• When you pay in: you usually receive tax relief on contributions.

• While your pension grows: investments are sheltered from tax.

• When you take money out: anything above your personal allowance is taxed as income.

• When you pass it on: from 2027, unused pensions may face inheritance tax.

Tax relief when you contribute

The government encourages pension saving by offering tax relief—but only up to certain limits.

For most people, this happens automatically. If you’re in a workplace pension, tax relief is usually applied through payroll. Basic-rate relief is built in, and many higher-rate taxpayers also receive the full benefit without needing to do anything. You’ll only need to claim manually if you’re paying into a personal pension or your scheme only applies basic-rate relief.

Relief at source

Here, your pension provider claims basic-rate tax relief for you.

Example:
You earn £30,000 and contribute £1,000 to a personal pension. Your provider reclaims £250 from HMRC, so £1,250 ends up in your pension pot.

Higher and additional-rate relief

If you earn over £50,270, you can usually claim extra relief through your self-assessment return, as explained on GOV.UK.

That means:

• An extra 20% on income taxed at 40%

• An extra 25% on income taxed at 45%

In many workplace schemes, this extra relief is already handled for you. With personal pensions, you often need to claim it yourself.

Contribution limits and allowances

Tax relief is capped at 100% of your earnings, with a standard annual allowance of £60,000. For high earners, this can be tapered down—sometimes as low as £10,000. The official thresholds are published on GOV.UK.

Even if you don’t earn anything, you can still contribute. Non-earners can put in up to £2,880 a year, which the government tops up to £3,600.

If you’ve already accessed your pension flexibly, the Money Purchase Annual Allowance (MPAA) may apply, reducing your annual limit to £10,000.

Tax-free growth inside the pension

One of pensions’ biggest advantages is what happens after your money goes in. Your investments grow free from capital gains tax and dividend tax.

If your pension doubles over ten years, HMRC doesn’t take a cut. Compare that with a general investment account, where tax would apply, and the benefit becomes clear.

Paying tax when you withdraw

When you take money out, it’s treated like income. Anything above your personal allowance is taxed under PAYE, just like a salary.

For workplace pensions, this is usually automatic. Your provider deducts the tax for you. You won’t normally need a tax return unless you have other income or more complex finances.

How the personal allowance works

For 2025/26, the personal allowance is £12,570. Your state pension, private pension withdrawals, wages, and rental income all count toward this total.

Examples:

• Claire receives £11,973 from the state pension and withdraws £10,000 from her pension. She stays within the basic-rate band.

• Martin takes a £40,000 lump sum on top of his state pension and immediately tips into higher-rate tax, losing 40% on part of it.

As one client once told me, “I thought I was only taxed if I kept working.” Sadly, pension income is still income—even if you’re enjoying cocktails in Spain.

Be careful with the 25% tax-free lump sum

You can usually take up to 25% tax-free, capped at £268,275 under current rules. It sounds generous—and it is—but taking it all at once can cause problems.

Example:
Sarah takes £100,000 tax-free from her £400,000 pension and leaves the rest invested. No issue.
John does the same, spends it quickly, and then needs £50,000 a year. His later withdrawals push him into higher-rate tax.

Coordinating with the state pension

The state pension is taxable, even though tax isn’t deducted at source. Instead, HMRC adjusts the tax code on your private pension or salary.

If your state pension is around £11,973, most of your personal allowance is already used before you touch your private pension. This often explains why people feel their pension is being “over-taxed”. It isn’t—it’s simply covering the tax due on the state pension.

Watch out for allowance traps

Three rules catch people out time and again:

• The £60,000 annual allowance

• The taper for incomes over £260,000

• The MPAA, which cuts allowances to £10,000 once flexible withdrawals begin

Emergency tax codes and reclaiming overpayments

First pension withdrawals often trigger an emergency tax code. HMRC assumes you’ll take the same amount every month.

Example:
Raj withdraws £10,000 once. HMRC taxes it as if he’ll take £120,000 that year, leaving him thousands out of pocket—temporarily.

You can usually reclaim this using forms P55, P53Z, or P50Z, but it’s better to plan ahead.

Choosing how to take your pension

You generally have three options:

Drawdown

Your money stays invested and you take income as needed.

• Pros: Flexible, great for managing tax bands

• Cons: Requires discipline and investment risk remains

Lump sums (UFPLS)

Each withdrawal is 25% tax-free, 75% taxable.

• Pros: Useful for one-off expenses

• Cons: Easy to trigger higher-rate tax or emergency codes

Annuity

You exchange your pension for a guaranteed income for life.

• Pros: Certainty and simplicity

• Cons: No flexibility and limited inheritance options

Inheritance and the 2027 rule change

Currently, pensions passed on before age 75 are often tax-free. After 75, beneficiaries pay income tax but not inheritance tax.

From 6 April 2027, the government plans to include unused pensions in estates for inheritance tax purposes (subject to Parliament). For larger estates, that could mean a 40% hit.

This makes planning—nominations, splitting pots, and using ISAs—more important than ever.

Where an Accountants really helps

Pensions don’t sit in a vacuum. They interact with salaries, rental income, ISAs, and estate planning.

We've seen people save thousands simply by spreading withdrawals, timing income better, or rebalancing pensions between partners. Sometimes, a single half-hour conversation completely changes the shape of someone’s retirement.
