Most people in the UK know they can take 25% of their pension tax-free. What catches them out is the rest. Take too much in one go and you can end up in the higher-rate band before you’ve even had time to enjoy your retirement holiday.
Pensions aren’t fully tax-free. You get relief on contributions, growth is sheltered, but withdrawals are taxed as income. From April 2027, unused pots could also count towards inheritance tax.
In this guide, we’ll walk you through each stage clearly, with real examples and common pitfalls, so you can see how the rules actually play out. By the end, you’ll know not just if pensions are taxed, but how to make the rules work for you.
Are pension plans taxed in the UK?
Yes, but not always in the way you think.
There are four main tax touchpoints:
- When you pay in – you usually get tax relief on contributions.
- While your pot grows – investments are sheltered from tax.
- When you take money out – it’s taxed as income above your personal allowance.
- When you pass it on – it may face inheritance tax from 2027.
Claim tax relief on contributions
The government rewards you for saving into a pension, but only up to certain limits.
Most people don’t need to do anything. If you’re paying into a workplace pension, your employer and pension provider normally sort the tax relief automatically through payroll. That means basic-rate relief is already built in, and many higher-rate taxpayers also get their full relief without lifting a finger. You only need to claim through self-assessment if you’re in a personal pension or if your scheme only applies basic-rate relief.
There are two ways you can claim tax relief on pension contributions:
Relief at source
Your pension provider will reclaim 20% (the basic tax rate) of your pension contributions and add this to your pension pot.
Example:
If you’re a basic-rate taxpayer earning £30,000 and you pay £1,000 into a personal pension, your provider reclaims £250 from HMRC, so £1,250 goes into your pot.
Higher and additional rate relief
If you’re a higher-rate taxpayer earning over £50,270, you can claim back through your self-assessment return, as stated by GOV.UK.
This equates to:
- 20% up to the amount of any income you have paid 40% tax on
- 25% up to the amount of any income you have paid 45% tax on
Note: In many workplace pensions, this extra relief is already applied via payroll. Only in some schemes (mainly personal pensions) do you need to claim it back yourself.
Contribution limits and the annual allowance
You can only get relief up to 100% of your earnings, with an annual allowance of £60,000. High earners face a tapered allowance, which can reduce their limit to £10,000. The official thresholds are published on GOV.UK’s pensions rates page.
Non-earners can still benefit. Even if you don’t have earnings, you can get tax relief on up to £3,600 gross (£2,880 of your own money plus £720 top-up from the government) each year.
The Money Purchase Annual Allowance (MPAA)
If you’ve already accessed your pot flexibly, the Money Purchase Annual Allowance (MPAA) can drop your allowance to £10,000.
Keep growth tax-free inside the pension
The best-kept secret about pensions is that once the money’s in, it grows tax-free.
That means if your investments double over a decade, you won’t pay capital gains tax or dividend tax inside the wrapper. Compare that with an ISA (also tax-free but with lower contribution limits) or a general investment account (where you’d pay tax).
Pay income tax when you take money
Every pound you take above your personal allowance is taxed under PAYE, just like wages.
For workplace pensions, this is usually automatic. Your provider applies PAYE and deducts the right tax each time you take an income. You don’t need to complete a tax return unless you have other income sources or more complex circumstances.
Personal allowance explained
For 2025/26, the personal allowance is £12,570. Add up your state pension, any wages, rental income, and the pension withdrawals. It all counts towards the tax bands.
Example:
- Claire takes her state pension of £11,973 and adds £10,000 from her DC pot. That pushes her just under the 20% basic-rate threshold.
- Martin takes a £40,000 lump sum on top of his state pension. He immediately tips into a higher-rate tax, losing 40% on part of that withdrawal.
I had one client who said, “I thought I was only taxed if I kept working.” Sadly not. Pension income is income, even if you’re sipping piña coladas in Spain.
Use the 25% tax-free lump sum with care
Most of us can take up to 25% of our pot tax-free, capped at £268,275 under current rules. That sounds like a lottery win. But using it all at once can backfire.
Example:
- Sarah has a £400,000 pot. She takes £100,000 as her tax-free cash, leaving £300,000 invested. That works fine.
- John does the same but spends his £100,000 in one go and then needs another £50,000 a year. Suddenly, his withdrawals fall into higher-rate tax bands.
Coordinate your state pension with private income
The state pension is taxable, even though HMRC doesn’t deduct tax from it directly. Instead, they adjust the tax code on your private pension or salary.
That means if your state pension is £11,973 (projected to rise by around 4.7% in April 2026 under the triple lock; final rate to be confirmed), most of your personal allowance is already used up before you’ve touched your private pension.
It’s easy to fall into the trap of not realising this and wondering why your workplace pension seemed overtaxed. It isn’t; it’s simply paying the tax on your state pension behind the scenes.
Watch the rules on allowances
There are three big pitfalls to be aware of:
- The £60,000 annual allowance, reduced if you earn over £260,000.
- The taper, which cuts your allowance by £1 for every £2 over that threshold.
- The MPAA, triggered once you take income flexibly, capping contributions at £10,000.
Avoid surprise tax codes and reclaim overpayments
When you take your first lump sum, HMRC often applies an “emergency tax code”. It’s a blunt instrument, taxing as if you’ll take the same amount every month.
Example: Raj takes a £10,000 withdrawal. HMRC taxes him as if he’ll take £120,000 that year. He ends up overpaying thousands.
First payments often use an emergency code such as 1257L W1/M1, which can cause too much tax to be deducted. You can reclaim using P55/P53Z/P50Z.
Choose the right withdrawal route
You generally have three options when it comes to withdrawing from your pension:
Drawdown
Think of a drawdown as treating your pension like a flexible bank account (with investment risks still in play). You keep your pot invested, and you decide how much to take and when.
- Upside: Flexible, you choose how much and when. Great for managing tax bands.
- Downside: It takes discipline. Spend too much early, or the markets fall, and you risk running out later.
Lump sum (UFPLS)
This option lets you take ad hoc chunks from your pot. Each time, 25% of the amount is tax-free, and the rest is taxed as income.
- Upside: Handy for big one-off spends such as a new car, home improvements or helping the kids.
- Downside: If you take a large lump sum in one tax year, it can shove you into a higher bracket and trigger an emergency tax code.
Annuity
Where you hand over part or all of your pot to an insurance company in exchange for a guaranteed income for life. The income is taxed under PAYE, just like a salary.
- Upside: Peace of mind. You’ll never run out of money from that annuity portion. It’s simple and steady.
- Downside: No flexibility. Once you’ve bought it, you can’t get the pot back. If you die early, your heirs may get little or nothing unless you’ve paid for a guarantee.
Plan for inheritance and the 2027 inheritance tax change
At the moment, if you die before 75, beneficiaries often get your pension tax-free. After 75, they pay income tax on withdrawals but not inheritance tax.
That is due to change on 6 April 2027, when the government plans to include most unused pots in your estate for inheritance tax (draft legislation; subject to Parliament). That could mean 40% tax on top for larger estates.
If you’re sitting on a big pension, it’s time to think about nominations, splitting pots, or using ISAs strategically.
When an accountant adds value
Why work with an accountant? Because pensions don’t exist in isolation. They mix with salaries, property income, ISAs, and estate plans.
I’ve seen savings of thousands simply by phasing withdrawals, coordinating with state pension timing, or rebalancing pots between partners.

Final thoughts
Pensions aren’t fully tax-free, but they are incredibly tax-efficient if you use them right. Relief on the way in, shelter during growth, and income tax on the way out.
Our advice? Don’t treat pensions as one-off pots of cash. Treat them as part of your lifetime tax plan. Look at your income bands, time your withdrawals, and get ahead of the 2027 changes.
