How Much Tax Will I Pay on My Pension? A Simple Guide to Retirement Withdrawals

After years of building up a pension, reaching the point where you can start using it should feel straightforward. But for many people, a new question quickly takes its place: “How much tax will I actually pay when I take money out?”

The answer depends on how much you withdraw, what other income you receive and how you choose to access your pension.

Understanding the basics can help you avoid unexpected tax bills and make more informed decisions about your retirement income.

How are pension withdrawals taxed?

With most defined contribution pensions, you can usually take up to 25% of your pension tax-free, subject to your available lump sum allowance. The standard lump sum allowance is currently £268,275, although some people may have a higher protected allowance.

Beyond any tax-free amount you’re entitled to, money you withdraw from your pension will generally be subject to Income Tax. Importantly, it isn’t taxed separately from everything else. Taxable pension withdrawals are added to your other taxable income for that tax year.

That could include income from:

  • The State Pension
  • Workplace or private pensions
  • Employment or self-employment
  • Taxable income from savings and investments 

It is your overall taxable income that determines how much Income Tax you ultimately pay.

How much can you receive before paying tax?

For the 2026/27 tax year, the standard Personal Allowance is £12,570. This is the amount of income most people can receive before paying Income Tax.

For taxpayers in England, Wales and Northern Ireland who receive the full standard Personal Allowance, the main Income Tax bands are: 

  • 20% basic rate on taxable income from £12,571 to £50,270
  • 40% higher rate on taxable income from £50,271 to £125,140
  • 45% additional rate on taxable income above £125,140

Your circumstances can affect your allowances and tax position, so these figures shouldn’t be viewed in isolation.

Importantly, moving into a higher tax band doesn’t mean all your income is taxed at that higher rate – generally, only the portion that falls within that band is. 

“But I thought 25% of my pension was tax-free?”

This is where pension withdrawals can become confusing. Being able to take up to 25% tax-free doesn’t necessarily mean you have to withdraw all your tax-free cash in one go.

Depending on your pension arrangements, you may have different options. For example, you might take some tax-free cash before drawing taxable income, or make withdrawals over time, with part of each withdrawal tax-free and the remainder taxable. 

The right approach depends on what you need the money for and how it fits into your wider retirement plan. Taking the maximum tax-free amount simply because it’s available isn’t automatically the best option.

Why taking too much at once can create a bigger tax bill

Imagine you need extra money for a large purchase during retirement.

It can be tempting to simply withdraw the full amount from your pension. But if most of that withdrawal is taxable, adding it to your State Pension and any other income could move part of your income into a higher tax band.

In some circumstances, spreading withdrawals across different tax years, or considering how pensions work alongside other available assets, may produce a different tax outcome. This is why it can be useful to plan withdrawals before making them rather than considering the tax consequences afterwards.

Watch out for tax on your first withdrawal

Another surprise can occur when you first access a pension flexibly. Pension providers normally deduct Income Tax through PAYE. In some cases, the initial tax deducted from a flexible pension payment may be higher than your eventual tax liability.

That doesn’t necessarily mean this is the amount of tax you’ll ultimately owe. Depending on the circumstances, overpaid tax may be reclaimed from HMRC or adjusted later. But if you’re relying on a particular amount arriving in your bank account, an unexpected deduction can be frustrating.

Why pension withdrawal planning matters

Once you retire, the question isn’t simply “How much can I take from my pension?”

A more useful question may be: “How can I create the income I need while using my pension as efficiently as possible?”

That means looking at the bigger picture, including:

  • How much income you actually need
  • Your State Pension and other pension income
  • Your available tax-free cash
  • Savings and investments outside your pension
  • Larger expenses you expect in the future
  • How long your retirement funds may need to last

A withdrawal that makes sense this year can also affect the money available later in retirement, so tax is only one part of the decision.
