What is the Emergency Tax Calculator?
The Emergency Tax Calculator is a simple tool that shows the impact of emergency tax on a first pension withdrawal.
When a provider has no tax code for you, they often tax that payment as if it were one month of a repeating salary. You only get a twelfth of your personal allowance against it, so a large lump can lose a lot of tax.
The calculator then compares that deduction with an estimate of the extra tax this payment should add over the year, given your other income, and shows how much of the extra may come back.
How the Calculator Works?
Enter the type of withdrawal, the gross amount, any tax-free share, other taxable income this year, and whether you live in England, Northern Ireland and Wales, or Scotland.
The calculator then applies an emergency tax code for tax year 2026/27. The payment is treated as one month of a repeating salary, so you only get a twelfth of the personal allowance against it. A first lump from a pension that has not been converted yet is usually 25% tax-free. Drawdown here assumes tax-free cash was already taken. National Insurance and later payslips once a real tax code arrives are left out. Figures are illustrative only, not advice.
Step 1: Add your withdrawal details
Choose a lump sum or drawdown income, the amount leaving the pot, the tax-free share, and any other taxable income this year.
Step 2: Choose your nation and next steps
Pick England, Northern Ireland and Wales, or Scotland. Say if this payment empties the pot, and if more payments are due before 5 April. Those last two only change the reclaim notes, not the tax figures.
Step 3: Review emergency tax, net cash and reclaim
See the emergency tax, an estimate of the extra tax this payment should add, what may come back, and how that emergency tax was worked out. Download a CSV if you want the figures in a spreadsheet.

Understanding Your Results
The three headline figures are how much tax is taken now, how much extra tax this payment should add given your other income, and how much of the extra may come back.
Emergency tax
This is the amount taken from this payment when the provider has no tax code for you yet. The payment is treated as one month of a repeating salary. You only get one twelfth of the personal allowance (£1,047.50) against the taxable part, then one twelfth of the 20%, 40% and 45% rates.
Correct tax on payment
This is an estimate of the extra income tax this payment would add over the year, given the other income you entered. It is not a full tax return.
Reclaimable
This is emergency tax minus that estimate. It never goes below £0. It is not a promise that HMRC will pay that amount.
What this leaves out
National Insurance, student loans, later payslips once a real tax code arrives, and how much tax-free cash you still have left are not in the model. Check your payslip, provider and GOV.UK before you act.

What a first withdrawal can look like
These examples show how emergency tax can hit a first pension payment. They use tax year 2026/27 and an emergency tax code for England, Northern Ireland and Wales. Change the numbers to match your own payment.
Pat, a first lump sum
£40,000 lump sum · 25% tax-free · no other income
Pat is taking a first £40,000 lump and has no other taxable income this year. £10,000 is tax-free. The other £30,000 is taxed as if it were one month of salary, so most of the personal allowance is ignored.
- Emergency tax: £11,878.87
- Correct tax on payment: £3,486.00
- Reclaimable: £8,392.87
What Pat takes from it
About £8,393 of the tax taken now may be extra. About £3,486 is closer to what this payment should cost with no other income. The calculator does not say whether Pat should take the lump.
Jo, drawdown with other income
£20,000 drawdown · fully taxable · £25,000 other income
Jo has already taken tax-free cash, so this £20,000 payment is all taxable. She also has £25,000 of other income, which has already used the personal allowance. Emergency tax still treats the payment as one month of salary.
- Emergency tax: £7,378.87
- Correct tax on payment: £4,000.00
- Reclaimable: £3,378.87
What Jo takes from it
About £4,000 of tax was always likely because of Jo’s other income. About £3,379 may be extra. The calculator does not say whether Jo should take the payment.
Sam, empties the pot
£15,000 lump sum · pot emptied · no more payments
Sam is taking the last £15,000 from this pot and has no other taxable income. After the tax-free share, the rest sits inside the personal allowance, so the estimated extra tax for the year is £0. The emergency code still takes tax now.
- Emergency tax: £3,452.67
- Correct tax on payment: £0.00
- Reclaimable: £3,452.67
What Sam takes from it
In this illustration the whole £3,453 taken now may come back, because the rest of the payment sits inside the personal allowance. The calculator does not say whether Sam should empty the pot.
What is the Emergency Tax Calculator?

What is emergency tax?
Emergency tax is the extra tax a provider can take when they have no tax code for you yet. The payment is taxed as if it were one month of a repeating salary, so you only get a twelfth of your personal allowance against it.
What is a UFPLS?
It is a lump sum from a pension that has not been converted yet. The calculator usually treats 25% as tax-free and the rest as taxable. It does not check how much tax-free cash you have left. For the size of that tax-free share, use the 25% tax-free lump sum calculator.
Why is so much tax taken?
Because you only get a twelfth of the personal allowance, and a twelfth of each tax rate, against this one payment. A large lump is treated like a huge monthly salary, so a lot of it can be taxed at 40% and 45%.
Can I get the extra tax back?
Often yes, once HMRC has the full year, or once a real tax code arrives for later payments. The calculator shows an estimated reclaimable amount. It is not a promise of a refund. GOV.UK explains how to claim a tax refund.
What are P55, P50Z and P53Z?
They are common in-year reclaim routes HMRC often points to, depending on whether the pot is empty and whether you have other income. The calculator shows a matching note. It does not tell you which form you must file.
Does this include Scotland?
Yes. The calculator uses published 2026/27 Scottish rates if you choose Scotland. England, Northern Ireland and Wales share the same bands in this model.
How is this different from the drawdown tax calculator?
The pension drawdown tax calculator looks at tax over a retirement income plan and only flags emergency tax. This calculator is a simple tool for the tax taken on one first payment. For tax-free cash size, use the 25% tax-free lump sum calculator.
Is this financial advice?
No. The calculator is an illustration only. It is not an HMRC bill and not a personal recommendation.
Can I export my results?
Yes. After the results, Get my CSV downloads your inputs, the emergency tax compare, and how that emergency tax was worked out.

Behind Retirement Calculators
Built from the questions I was asking myself
I'm Ryan, the person behind Retirement Calculators. I started the site after selling an online business and trying to understand what our pensions, ISAs, investments and property actually meant for the way we wanted to live.
The calculators are built around those real decisions: whether you could work less, retire earlier, spend more now or use your money differently. They will not give you a perfect answer, but they can make the trade-offs much easier to see.
