Most people don’t think twice about their tax code — until it eats into their pension. A small tweak in those numbers and letters on your payslip can decide whether you get the right income, too much taken away, or months of waiting to claw your money back.
That’s why the HMRC Pension Tax Code Rule Change has become such an important topic. It’s designed to fix a problem that has frustrated thousands of retirees: emergency tax codes and overpaid taxes. In fact, HMRC refunded more than £190 million to pensioners last year because of incorrect taxation on withdrawals.
So what’s changing, and how will the HMRC Pension Tax Code Rule Change affect your state pension, workplace scheme, or private pension pot?
What Is a Pension Tax Code?
A tax code is HMRC’s way of telling employers or pension providers how much tax to deduct from your income. For pensioners, it’s more complicated than for workers because income often comes from multiple sources.
- State Pension – Counts as taxable income, but no tax is taken off before payment. HMRC adjusts other income codes to balance it.
- Workplace pensions – Taxed at source under PAYE, using the code HMRC supplies.
- Private pensions – Flexible drawdowns and lump sums are common, but this flexibility increases the risk of tax code errors.
The issue arises when HMRC doesn’t have a full picture of your income. That’s when temporary or emergency codes are used.
Example:
If you take a £12,000 lump sum, your provider might assume you’ll withdraw that amount every month. HMRC then treats you as if you earn £144,000 a year. Result: far too much tax deducted, and a long wait for a refund.
What the HMRC Pension Tax Code Rule Change Means for Pensioners
From April 2024 into the 2025/26 tax year, HMRC rolled out updates to reduce over-taxation and emergency codes.
| Before | After Rule Change |
| Emergency codes are often applied to the first withdrawals | Fewer emergency codes used, especially on lump sums |
| Pension providers had unclear guidance | Clearer instructions for tax withdrawals correctly |
| Refunds often took months | Faster refund process (aim: 30 days) |
This reform is part of the government’s wider effort to modernise pension taxation and reduce the billions tied up in unnecessary refunds.
Common Issues Pensioners Still Face
Even with the improvements, some problems remain:
- Emergency tax still applies to some first withdrawals
- Overpayment of tax occurs when providers assume the wrong income pattern
- Slow refunds — HMRC aims for 30 days, but delays happen
- Confusion across multiple providers, especially if you draw from state, private, and workplace pensions
For pensioners relying on income for daily expenses, even short delays can cause real stress.
How to Check If Your Pension Tax Code Is Correct
It’s important to keep an eye on your tax code. Here’s a quick checklist:
- Check your HMRC app or online personal tax account for live updates
Look at your pension payslips — they show which code is being used
Review your annual coding notice (P2) from HMRC
Warning signs: If you see a code like 1257L M1, that’s an emergency code. Contact HMRC or your pension provider immediately.
How to Claim Back Overpaid Pension Tax
If you’ve overpaid, you don’t need to wait until the end of the tax year — you can reclaim it earlier.
- Form P55 – If you took part of your pension pot and still have funds left
- Form P53Z – If you took the whole pot but still have other taxable income
- Form P50Z – If you took the whole pot and have no further income that year
Refunds usually take around 30 days and go straight into your bank account — but patience is often needed.
What the HMRC Pension Tax Code Rule Change Means for Different Pensions
- State Pension → Taxable, but no tax is deducted before payment. HMRC adjusts codes on other income.
- Workplace Pensions → Taxed via PAYE, generally smoother, but errors can occur with multiple income sources.
- Private Pensions → The most affected; flexible withdrawals were where emergency codes hit hardest.
- Inherited Pensions & Death Benefits → Tax rules depend on the saver’s age at death. Representatives may need to manage this carefully.
Planning Ahead: Avoiding Nasty Surprises
The new rules help, but pensioners should still stay proactive:
- Keep HMRC updated – Report income changes quickly
- Check codes every April – Start of a new tax year is prime time for mistakes
- Spread withdrawals – Smaller, regular amounts can help avoid emergency codes
- Get advice – A financial adviser can suggest tax-efficient withdrawal strategies
Key Takeaways
- HMRC’s pension tax code rule change reduces the use of emergency codes and speeds up refunds.
- Emergency codes still exist — but should be less common.
- Pensioners should check tax codes regularly on payslips or the HMRC app.
- Refunds can be claimed with forms P55, P53Z, or P50Z.
- Planning withdrawals carefully can reduce stress and protect income.
FAQs
Q: What is the HMRC pension tax code rule change?
It’s an update to how HMRC taxes pension withdrawals — fewer emergency codes and faster refunds.
Q: How do I know if I’m on the wrong tax code?
Check your payslip or HMRC app. Emergency codes like 1257L M1 or unusually high deductions are red flags.
Q: Do I pay tax on my UK State Pension?
Yes. The State Pension is taxable, though tax isn’t taken directly. HMRC adjusts your other income codes.
Q: How much of my pension is tax-free?
Most people can withdraw 25% of a pension pot tax-free. The rest is taxed as income.
Q: What if I overpay pension tax?
You can reclaim it using HMRC forms (P55, P53Z, P50Z). Refunds usually arrive in about a month.
Final Words
The HMRC pension tax code rule change is a welcome step forward. It won’t eliminate errors completely, but it should mean fewer pensioners stuck waiting months for refunds.
The safest approach? Check your code, question anything unusual, and reclaim overpayments quickly. Retirement income should be for living life, not loaning HMRC your money by mistake.
