Emergency Tax on Your First Pension Withdrawal: How to Reclaim It 2026/27
Your first flexible pension withdrawal is usually taxed on a month 1 emergency code, which can overtax a one-off lump sum by thousands. Here is why it happens and how to reclaim it in 2026/27.
Why the first withdrawal is overtaxed
When you take taxable income from a defined contribution pension for the first time, your provider usually does not have a tax code from HMRC for you. By law it must then apply an emergency code on a month 1 basis.
A month 1 code treats a one-off payment as if you will receive the same amount every single month for the rest of the tax year. So it gives you only one twelfth of your Personal Allowance and one twelfth of each tax band against a single large payment. The result is a much bigger tax deduction than you actually owe.
A worked example for 2026/27
Sarah, 60, takes a GBP 30,000 taxable withdrawal (this is the part after her 25% tax-free cash). She has no other income yet this year.
On the correct annual basis, after her Personal Allowance of GBP 12,570, only GBP 17,430 would be taxable, all at 20%, giving GBP 3,486 of tax.
But under the month 1 emergency code the provider gives her only one twelfth of the allowance and bands:
- One twelfth of GBP 12,570 = GBP 1,047.50 tax-free
- One twelfth of the GBP 37,700 basic band = GBP 3,141.67 taxed at 20%
- One twelfth of the higher band applied at 40%
- The top slice of the GBP 30,000 taxed at 45%
This can produce a deduction of well over GBP 9,000 on a payment that should only attract around GBP 3,486 of tax. The difference is hers to reclaim.
How to reclaim it
Which form you use depends on what you did:
- P55: you took a one-off lump sum but left money in the pension and are not taking regular payments.
- P50Z: you emptied the whole pot and have no other taxable income this year.
- P53Z: you emptied the whole pot but do have other taxable income.
HMRC typically processes these refunds within around 30 days. If you do nothing, HMRC will usually correct the position automatically through your tax code or at the end of the tax year, but that can take many months, leaving you out of pocket in the meantime.
How to reduce the problem in the first place
- Take a small first withdrawal (for example GBP 100). This prompts HMRC to issue your correct code to the provider.
- Take the larger amount in a later payment, by which point the right code should apply.
- Spread withdrawals across tax years to use more of your Personal Allowance and stay in lower bands.
- Keep records of the dates and amounts so you can complete the reclaim form quickly.
The figures above use the rUK Personal Allowance of GBP 12,570 and the standard bands. Scottish taxpayers have different rates and should check the Scottish bands.
