Emergency Tax on Pension Withdrawals: What You Need to Know
Many people receive unexpected tax deductions on their first pension withdrawal. Learn how emergency tax works, why it happens, and how to claim a refund from HMRC.
Why Is My First Pension Withdrawal Taxed So Heavily?
If you've recently taken your first withdrawal from a pension in drawdown and found the tax deducted was much higher than expected, you're not alone. This is one of the most common complaints among people accessing their pension for the first time, and it's down to something called emergency tax.
Emergency tax is a temporary measure used by pension providers when they don't have your correct tax code. The good news is that any overpaid tax can be reclaimed - but understanding why this happens can help you plan ahead and avoid nasty surprises.
How Does Emergency Tax Work?
When you take money from your pension, your provider must deduct income tax under PAYE (Pay As You Earn). However, unlike your employer, pension providers often don't have your tax code when you first access your pension.
Without a proper tax code, providers use what's known as an emergency tax code. This code assumes you'll be making the same withdrawal every month for the rest of the tax year. If you're taking a one-off lump sum, this can result in a significant over-deduction of tax.
Example of Emergency Tax in Action
Consider this scenario: Sarah takes a one-off withdrawal of £20,000 from her pension (after her 25% tax-free lump sum). Under emergency tax rules, the provider might assume she'll take £20,000 every month - that's £240,000 for the year.
This pushes her into higher tax bands, resulting in much more tax being deducted than she actually owes. If she's only taking this single withdrawal and has no other income, her actual tax bill would be much lower.
Emergency Tax Codes Explained
There are three main types of emergency tax codes you might encounter:
- 0T (cumulative) - No tax-free personal allowance is given, and tax is calculated cumulatively based on earnings so far in the tax year
- 0T W1/M1 (week 1/month 1) - No personal allowance, and tax is calculated as if this is your only income for that period, multiplied to estimate the full year
- BR (basic rate) - All income taxed at 20% with no personal allowance
The 'W1' or 'M1' suffix indicates a non-cumulative or 'week 1/month 1' basis, meaning your previous earnings that tax year aren't considered. This often leads to the highest over-deductions.
Who Is Most Affected?
Emergency tax particularly affects people in these situations:
- Those taking their first pension withdrawal
- People taking large one-off lump sums
- Those who have recently retired and no longer have employment income
- Anyone accessing a pension from a provider they haven't used before
- People making withdrawals early in the tax year (April/May)
If you're still working and your employer has already used your personal allowance, emergency tax may actually be closer to correct - but even then, the calculation method can cause issues.
How Much Tax Should You Actually Pay?
Understanding the standard income tax rates can help you estimate what you should owe. For the 2025/26 tax year, the rates are:
- Personal Allowance: £0 - £12,570 (0% tax)
- Basic Rate: £12,571 - £50,270 (20% tax)
- Higher Rate: £50,271 - £125,140 (40% tax)
- Additional Rate: Over £125,140 (45% tax)
Note that the personal allowance reduces by £1 for every £2 of income above £100,000, disappearing entirely at £125,140.
Your pension withdrawal is added to any other income you have that year (employment, state pension, rental income, etc.) to determine which tax bands apply.
How to Avoid Emergency Tax
While emergency tax can't always be avoided, there are steps that may help:
1. Take a Small Initial Withdrawal
Some people take a small first withdrawal (perhaps just a few hundred pounds) to trigger the tax code process. Once HMRC issues your correct code to the provider, subsequent withdrawals should be taxed correctly. This approach typically takes 30-60 days to resolve.
2. Provide Your P45
If you've recently stopped working, providing your P45 to your pension provider can help them apply the correct tax code from the start.
3. Time Your Withdrawals
Taking withdrawals later in the tax year gives HMRC more time to issue correct tax codes to providers. Withdrawals made in March may face fewer emergency tax issues than those in April or May.
4. Spread Withdrawals Across Tax Years
Taking smaller withdrawals across multiple tax years can keep you in lower tax bands overall, reducing both actual tax and potential emergency tax issues.
How to Claim Back Overpaid Tax
If you've had emergency tax deducted, you have several options to reclaim it:
Option 1: Wait for Automatic Correction
HMRC will eventually receive information about your pension withdrawal and recalculate your tax. If you've overpaid, they'll typically issue a refund automatically - but this can take until after the end of the tax year.
Option 2: Complete an HMRC Form
For faster repayment, HMRC provides specific forms depending on your situation:
- P50Z: If you've withdrawn all your pension and have no other income
- P53Z: If you've withdrawn all your pension but have other taxable income
- P55: If you've taken only part of your pension
These forms are available on the HMRC website and can be submitted online or by post. Claims are typically processed within 30 days.
Option 3: Self Assessment
If you complete a Self Assessment tax return, any overpaid tax will be calculated and refunded through that process. This is automatic but means waiting until you file your return.
What Information Will You Need?
To claim a tax refund, you'll typically need:
- Your National Insurance number
- Details of the pension withdrawal (amount, date, tax deducted)
- A P45 from your pension provider (usually provided after withdrawal)
- Details of any other income in the tax year
- Your bank details for the refund
Keep all documentation from your pension provider as this will be needed for any claim.
Planning Ahead
Emergency tax is frustrating, but it's a temporary administrative issue rather than a permanent tax increase. The key points to remember:
- Any overpaid tax will be refunded - you won't lose money permanently
- Using HMRC forms speeds up the refund process significantly
- Small initial withdrawals can help establish correct tax codes
- Timing and spreading withdrawals can reduce the issue
- Your actual tax liability depends on your total income for the year

When to Seek Professional Advice
While emergency tax itself is straightforward, pension withdrawals interact with various aspects of your financial situation. Tax efficiency, withdrawal sequencing, and long-term sustainability all benefit from proper planning.
