When you take your first pension withdrawal — particularly from a SIPP or personal pension in drawdown — it is very common to have emergency tax deducted at a rate significantly higher than your actual liability. This is not a mistake in the usual sense: it is HMRC’s provisional approach when no current tax code exists. But it means you may receive considerably less than you expected, and you need to take steps to get the overpaid tax back.

Why Emergency Tax Happens on Pension Withdrawals
When you take a pension withdrawal, the provider must deduct income tax through PAYE. To do that, they need a tax code from HMRC. If they do not have one — which is common on a first withdrawal — they must apply a provisional code.
The provisional code HMRC instructs providers to use is the emergency code on a Month 1 basis. This means:
- Your personal allowance (£12,570 in 2026/27) is divided by 12 to give £1,047.50 per month
- Only that monthly allowance is set against the withdrawal — no carry-forward of unused allowance from earlier in the tax year
- The entire withdrawal is treated as if it is a regular monthly payment
- If you take £10,000 in one withdrawal, HMRC treats it as £10,000/month = £120,000/year — heavily taxed
The Annualisation Problem
| Withdrawal | Provider assumes annual income | Actual likely annual income | Emergency tax rate |
|---|---|---|---|
| £5,000 one-off | £60,000/year | £20,000 | 40% on most of it |
| £10,000 one-off | £120,000/year | £25,000 | 40–45% on most of it |
| £20,000 one-off | £240,000/year | £30,000 | 45% on most of it |
The annualisation effect creates large overpayments on any lump sum withdrawal. The table above illustrates why someone taking a £20,000 withdrawal expecting a 20% tax bill may receive considerably less and face a significant wait to recover the difference.
How Much Can You Overpay?
Worked Example: James is 60 and takes a £15,000 lump sum drawdown payment from his SIPP. It is his only income in the tax year. His actual income tax liability is zero — the withdrawal is within his personal allowance of £12,570, and the remaining £2,430 falls in the basic rate band at 20%, a tax bill of £486.
Emergency tax applied by the provider:
- Treats the £15,000 as £180,000/year income
- Applies 40–45% tax to most of it
- Deducts approximately £5,500–£6,500 in tax
James should receive £14,514 but actually receives approximately £8,500–£9,000 due to emergency tax. He overpays by approximately £5,000–£6,000. This is all recoverable — but he needs to reclaim it rather than wait.
The Three Reclaim Forms
HMRC provides three forms depending on your circumstances:
| Form | When to use it |
|---|---|
| P55 | You have taken a partial drawdown — you still have money in the pension and have not taken it all out |
| P50Z | You have taken your entire pension pot in one go and have fully retired |
| P53 | You have taken a small pension pot (trivial commutation) or a UFPLS from a small pension |
All three can be submitted online via GOV.UK or by post. You will need:
- Details of the pension payment received (from the pension provider)
- Your P45 if you have one
- Your National Insurance number
- Your personal tax account details (if submitting online)
Refunds are typically processed within 30 days of HMRC receiving the form. This is significantly faster than waiting for automatic year-end reconciliation, which may not result in a refund until summer or autumn after the relevant tax year.
If You Do Not Reclaim
If you do not submit a reclaim form, HMRC will eventually reconcile your tax position automatically through its end-of-year PAYE reconciliation process. This typically runs between June and November following the tax year end. The process:
- HMRC compares all income and tax deducted during the tax year
- Identifies any overpayment
- Issues a P800 notice and a refund
The refund happens, but typically 6–12 months after the withdrawal. If you need the money sooner, use the reclaim form.
How to Avoid Emergency Tax on Future Withdrawals
Once HMRC has a real tax code for you — issued after your first withdrawal triggers the reconciliation process — subsequent withdrawals from the same provider in the same tax year should be taxed correctly.
To avoid emergency tax on future withdrawals from different providers:
- Your pension provider may request a tax code directly from HMRC once your details are registered
- Keep your GOV.UK personal tax account updated with your expected income
- If you are making a large one-off withdrawal, contact HMRC beforehand to confirm whether a tax code will be in place
Emergency Tax vs Actual Liability: Planning the Withdrawal
If you know a first withdrawal will be emergency-taxed, you have two options:
- Take the full amount you want, accept the emergency tax deduction, and reclaim the overpayment (typically 30-day wait)
- Take a smaller initial withdrawal (e.g. £1) to establish the tax code, then make the larger withdrawal once HMRC issues the correct code to your provider — typically 4–6 weeks later
Option 2 avoids emergency tax entirely but delays access to the main sum.
How Emergency Tax Interacts With Other Income
Emergency tax is particularly problematic if you have other income sources (salary, self-employed income, State Pension) and have already used part of your personal allowance. The Month 1 basis ignores allowance already used in the tax year and does not coordinate with other income. This can create:
- Double taxation on the same allowance (offset partially at year end)
- Income pushed into higher rate bands that would otherwise have been basic rate
