Thousands of UK pensioners are receiving unexpected tax refunds due to overcharges on lump-sum pension withdrawals. This issue stems from HMRC’s emergency tax codes, which can incorrectly calculate tax based on assumptions of regular income.
Many retirees are discovering they’ve paid thousands more than necessary, with refunds often delayed. With changes to pension tax rules and inheritance tax coming into effect, understanding these overcharges has become even more important.
This blog breaks down who is affected, how to check eligibility, and what to do to reclaim overpaid tax.
Why Are Thousands of UK Pensioners Receiving Unexpected Tax Refunds from HMRC?
Recent data has revealed that pensioners across the UK are being refunded significant sums due to emergency tax overcharges. This issue affects those who withdraw lump sums from their pensions, particularly under the pension freedoms introduced in 2015.
HMRC applies an “emergency” tax code assuming the withdrawal will be made monthly for the rest of the year, resulting in inflated tax deductions.
Key Highlights:
- Around 60,000 pensioners claimed refunds in the 2023/24 tax year.
- This represents a 20% increase from the previous year.
- Since 2015, HMRC has refunded £1.4 billion to overcharged pensioners.
- Emergency tax codes incorrectly assume monthly income instead of one-time withdrawals.
- Refunds can take time and often require the pensioner to manually claim.
This ongoing issue has become a source of financial stress for many retirees who were unaware they had overpaid until receiving unexpectedly high tax bills.
What Triggers These Emergency Tax Charges on Pension Withdrawals?
Emergency tax overcharges usually stem from how HMRC calculates income tax on pension withdrawals, especially when individuals are making a lump-sum withdrawal for the first time.
Month-One Tax Code Misapplication
When someone withdraws money from their pension for the first time, HMRC often uses a “Month-One” emergency tax code.
This code assumes the amount withdrawn is monthly income, and then calculates tax as if the person will receive the same amount every month for the rest of the tax year.
One-Off Withdrawals Misinterpreted
The system fails to recognise that many pensioners make a single large withdrawal, not a recurring one. This misinterpretation results in higher income tax being deducted than legally required.
Lack of Real-Time Adjustment
HMRC does not automatically update tax codes in real-time for one-off withdrawals. This delay can lead to pensioners being left out of pocket for weeks or even months until a refund is processed.
How Much Money Are Pensioners Actually Reclaiming from HMRC?
Thousands of pensioners are reclaiming significant amounts after being overcharged tax on lump-sum withdrawals. While many refunds range between £2,000 and £5,000, some retirees have received far more.
- Average refund value in 2023/24: £3,342
- This was an increase of £280 (9%) compared to 2022/23
- Largest refunds exceeded £100,000 in isolated cases
These figures highlight the extent of the problem and the importance of understanding whether you may have been overcharged.
Who Are the Pensioners Receiving £10,000+ in Refunds?
The group receiving large refunds includes retirees who made substantial single withdrawals, often in preparation for large expenses or to distribute wealth to family.
- Around 11,700 pensioners reclaimed £5,000 or more
- Approximately 2,400 individuals received refunds exceeding £10,000
- The top 25 refund cases averaged an astonishing £106,900 each
Such high figures reflect a combination of large pension pots and the severe impact of emergency tax coding when withdrawals are miscalculated as ongoing income.
What Was the Average Refund in 2023/24?
The average refund amount has increased year over year, signalling both a greater volume of large withdrawals and growing awareness among retirees about their ability to claim back overpaid tax.
| Tax Year | Average Refund Amount | Year-on-Year Increase |
| 2022/23 | £3,062 | — |
| 2023/24 | £3,342 | £280 / +9% |
Pensioners receiving these refunds are not only regaining funds owed to them but are also increasingly using this data to better plan future withdrawals.
Are You Eligible for a Pension Tax Refund – And How Can You Check?
Many retirees may not realise they’re eligible for a refund until they receive a tax calculation letter or a reduced pension balance after a withdrawal.
Who Qualifies for a Refund?
You may be eligible if:
- You withdrew a lump sum from your pension and were taxed using an emergency tax code
- You made a first-time withdrawal from a defined contribution pension
- Your P45 details were not passed correctly to HMRC at the time of the withdrawal
- You withdrew more than your 25% tax-free allowance in a single transaction
How to Check?
Start by reviewing your pension payment statements and looking for large tax deductions. If the tax seems disproportionately high, especially for one-time withdrawals, it’s worth checking your HMRC personal tax account. The platform shows how your income was calculated and any applied codes.
What Is the Process for Claiming an HMRC Pension Tax Refund?
Claiming a refund involves submitting the correct HMRC form based on your circumstances. The process is relatively straightforward but can differ depending on whether you’ve started receiving your full pension or just made a single withdrawal.
Required HMRC Forms
- Form P55: For those who have made a withdrawal but are not taking regular income
- Form P50Z: For individuals who have taken their entire pension pot and are no longer working
- Form P53Z: For those who have taken their entire pension and are still working
How to Claim?
- Visit the official HMRC website or use your Government Gateway account
- Choose the form that matches your situation
- Submit online or by post with supporting documentation (e.g. pension withdrawal statement)
- Most claims are processed in 2 to 6 weeks
Once approved, the refund is paid directly to your nominated bank account without unnecessary processing delays.
Can You Prevent Being Overcharged on Future Pension Withdrawals?
While the emergency tax code issue can’t be entirely eliminated, there are proactive steps pensioners can take to reduce the risk of overpayment in the future.
Making smaller, phased withdrawals instead of a single large one can help mitigate tax code errors. Advising your pension provider in advance or contacting HMRC to discuss your intentions may help adjust the tax coding beforehand.
From April 2024, automatic tax code updates have been introduced, which will benefit those drawing private pension income for the first time, but manual oversight is still recommended.
What Are the Implications of Inheritance Tax Changes on Pension Withdrawals?
The introduction of inheritance tax (IHT) on unused pension funds from 2027 is changing how retirees use their pension pots. Currently, pensions are a tax-efficient way to pass on wealth, but that benefit will be curtailed under the new rules.
What’s Changing?
- From 2027, unused defined contribution pensions may be subject to IHT
- This is leading many retirees to withdraw larger sums earlier
- These larger withdrawals are more likely to trigger emergency tax overcharges
Potential Financial Planning Responses:
- Retirees are making lifetime gifts to family while they’re alive
- Financial planners are advising on withdrawal timing and tax mitigation
- HMRC acknowledges that the overcharge problem may worsen as this trend grows
The tax refund issue, combined with the IHT policy shift, underscores the need for careful retirement planning and regular tax code reviews.
Conclusion
The rise in pension tax refunds highlights a persistent flaw in HMRC’s treatment of lump-sum withdrawals. With thousands affected and millions reclaimed, it’s clear that many pensioners have unknowingly overpaid.
Staying informed, checking your withdrawal taxes, and acting promptly can ensure that you are not left out of pocket.
As tax rules continue to evolve, particularly with the 2027 inheritance tax change, retirees should remain proactive about their pension planning and engage with financial tools and advice when necessary.
