Picture this: you’re 55, ready to tap into your pension for the first time, and HMRC slaps you with an emergency tax bill that assumes you’ll be withdrawing the same massive amount every month for the rest of the year. Spoiler alert: you won’t be.
This HMRC pension emergency tax system has left thousands of pension savers seriously out of pocket. In 2023-24 alone, 6,000 people successfully claimed pension tax refunds after HMRC overcharged them on pension withdrawals—that’s a 20% jump from the year before. We’re talking about some eye-watering emergency tax refund amounts here, with the biggest pension withdrawal refunds hitting six figures.
Here’s why this HMRC pension tax chaos is happening and what you need to know to avoid getting caught in HMRC’s emergency tax trap on pension withdrawals.
HMRC Pension Tax Overcharge Statistics: The Eye-Watering Numbers
The Royal London pension tax refund data paints a stark picture of HMRC overcharging. Around 2,400 savers managed to claw back more than £10,000 each in emergency tax refunds, whilst 11,700 got £5,000+ returned from HMRC pension tax overcharges. The average pension emergency tax refund? £3,342—up £280 from the previous year.
The top 25 emergency tax refunds averaged £106,897. That’s not pocket change—that’s life-changing money sitting in HMRC’s coffers whilst it should be in retirees’ bank accounts.
Clare Moffat from Royal London stated: “Not only do these emergency taxes usually come as a massive shock, the unexpected pension tax amount can also scupper people’s carefully laid plans.”
How HMRC Emergency Tax on Pension Withdrawals Works
Since 2015, pension withdrawal rules let you access some or all of your defined contribution pension savings from age 55. The first 25% comes out tax-free (capped at £268,275), but the remaining 75% gets taxed on pension withdrawals.
Here’s where HMRC pension tax gets problematic. When HMRC doesn’t have a proper tax code for your pension withdrawal, they default to “emergency tax on pensions.” This flawed emergency tax system assumes whatever you withdraw will be your monthly income for the entire tax year.
Why Emergency Tax Creates Pension Overcharges
So if you take out £50,000 as a one-off pension withdrawal, HMRC emergency tax treats you as if you’re earning £50,000 every single month. It’s like assuming someone who buys a car will purchase the same car every week for a year. Makes no sense for pension withdrawals, right?
The HMRC Pension Tax Refund Process: Paperwork Prison
Want your emergency tax refund on pension withdrawals back quickly? Better hope you’ve got your HMRC refund forms sorted. HMRC makes you fill out specific paperwork to get faster pension tax refunds. Miss this step, and you’re stuck waiting until they review everything at the end of the tax year.
That could mean being out of pocket for months—not exactly ideal whilst you’re trying to fund your retirement or handle a financial emergency with your pension withdrawal.
Why HMRC Emergency Tax Problems on Pension Withdrawals Are Getting Worse
HMRC recently announced they’ll overhaul their emergency pension tax system, promising quicker pension tax refunds. Sounds great, except they’re not actually stopping the pension tax overcharging in the first place.
The kicker: HMRC emergency tax issues might get worse. With pensions now subject to inheritance tax, more people are considering withdrawing larger lump sums to avoid passing tax problems to their children. More big pension withdrawals = more emergency tax disasters on pension withdrawals.
“The problem of emergency taxes on pension withdrawals isn’t going away, and there’s a chance it could get worse,” warns Moffat.
How to Avoid HMRC Emergency Tax on Pension Withdrawals
If you’re planning a pension withdrawal to avoid HMRC emergency tax overcharges:
- Get your HMRC tax code sorted before making pension withdrawals
- Keep those emergency tax refund forms handy
- Don’t assume HMRC will automatically fix pension tax overcharges
- Consider smaller, staged pension withdrawals if possible
- Contact HMRC before large pension withdrawals to discuss tax codes

The bottom line? HMRC’s emergency pension tax system is broken, and until they actually fix the root cause of pension tax overcharges, thousands more savers will keep getting caught in this expensive emergency tax trap.
