What EPS Tax Refunds Are and How They Work

EPS tax refunds are money returned to you when you overpay taxes on earnings from an employer pension scheme

An EPS (Earnings-Related Pension Scheme) tax refund happens when you pay too much income tax on money you receive from a workplace pension. This typically occurs when you have multiple income sources—such as a pension and employment income, or two pensions—and your total tax-free allowance wasn't used correctly across all of them. The tax authority then owes you the difference.

The refund comes from HM Revenue & Customs (HMRC), the UK tax authority. It is not a special program or benefit you request—it is a correction of your tax record. If HMRC identifies the overpayment during a routine review, they will contact you. If you spot it first, you can report it yourself.

The amount varies widely depending on your income, how long the overpayment lasted, and which tax year it occurred in. Someone who overpaid by £50 for one year will receive a smaller refund than someone who overpaid by £500 across three years.

Key Takeaways

• EPS tax refunds occur when HMRC collects more income tax than you owe on pension income, usually because multiple income sources were not coordinated correctly.
• HMRC will typically identify and contact you about the overpayment, but you can also report it yourself if you discover it first.
• Refunds are processed through your tax record and paid directly to your bank account, usually within four to six weeks of approval.
• You will need your National Insurance number, pension provider details, and records of the tax years in question to report an overpayment.

How EPS overpayments happen

The most common cause is a mismatch between your pension income and your employment income. If you receive a workplace pension and also work part-time, your employer may not know about the pension. They then explore your full personal allowance to your wages, and your pension provider does the same. You end up using your allowance twice, and HMRC collects tax on income that should have been covered.

Another scenario involves the Marriage Allowance or other tax relief. If you are may have access to to transfer unused allowance to a spouse or partner, but your pension provider did not account for this, you may have paid tax on income that should have been protected.

A third cause is a change in your circumstances mid-year—such as retiring, starting a new job, or a pension payment stopping—that was not reflected in your tax code quickly enough. HMRC updates tax codes based on information from employers and pension providers, but there can be a lag of several weeks.

How to check if you are owed a refund

Log into your HMRC online account using your National Insurance number and password. You can access this through the HMRC website or the HMRC app. Your tax account will show your income from all sources for the current and previous tax years, along with the tax paid.

Look at the "Income tax" section and compare the tax paid against the tax owed. If the amount paid is higher, the difference is what you may be owed. HMRC will usually flag this with a message saying a refund is due or that they are reviewing your account.

If you do not have an online account, you can call HMRC's Income Tax helpline on 0300 200 3300 (Monday to Friday, 8am to 6pm). Have your National Insurance number and details of your pension and employment income ready. They will check your record and tell you whether a refund is due.

How refunds are processed and paid

Once HMRC confirms an overpayment, they will issue the refund to the bank account registered with your tax record. This is usually the account where your tax credits or benefits are paid, or the account you provided when you last contacted HMRC.

Processing time varies. If HMRC initiates the refund, it typically arrives within four to six weeks. If you report the overpayment yourself, HMRC may take longer—sometimes eight to twelve weeks—because they need to verify the information before releasing the money.

You will receive a letter or notification in your online account confirming the refund amount and the expected payment date. Keep this for your records, as it serves as proof of the refund if you need it for any reason.

What to do if you think you are owed a refund

Start by checking your online HMRC account. If you see a refund pending, do nothing—HMRC will process it automatically. If you do not see anything but believe you have overpaid, contact HMRC directly.

Gather the following before you call or write: your National Insurance number, the tax years you believe were affected, your pension provider's name and reference number, details of any other income during those years, and payslips or pension statements showing the tax deducted.

You can report an overpayment by phone, post, or through your online account. The phone route is fastest if you have all your information ready. If you prefer to write, send your details to your local HMRC office (the address is on any tax letter you have received). Include a clear explanation of why you believe you overpaid and attach copies of supporting documents.

Refunds and other tax credits or debts

If you owe HMRC money from a previous year—such as unpaid tax or an overpayment of tax credits—HMRC may offset your EPS refund against that debt. This means the refund will be used to pay what you owe, and you will not receive cash.

HMRC will notify you in writing if this is happening. If you believe the offset is incorrect or you have a hardship reason why you need the refund, you can contact HMRC to discuss it. They have discretion to release refunds in some cases, but this is not may provide.

If you have a current debt and are concerned about a refund being taken, contact HMRC before the refund is processed to understand your options.

Frequently Asked Questions

How long does it take to get an EPS tax refund?

If HMRC identifies the overpayment and initiates the refund, you will usually receive it within four to six weeks. If you report it yourself, allow eight to twelve weeks because HMRC needs time to verify your information before releasing the money.

Can I claim a refund for years that have already passed?

Yes. You can claim back overpaid tax for up to four years in the past, as long as you have evidence of the overpayment. The four-year window runs from the end of the tax year in which the overpayment occurred. Contact HMRC with details of the years affected and supporting documents.

What if HMRC says I do not have an overpayment?

Ask HMRC to explain their decision in writing. If you disagree, you can request a review of their decision within 30 days. Provide any additional evidence you have—such as pension statements or payslips—that shows the overpayment. If you remain unsatisfied, you can appeal to the independent Tax Tribunal.

Will I get interest on my refund?

HMRC does not pay interest on tax refunds. You receive only the amount of tax that was overpaid, not any additional compensation for the time the money was held.

What if my bank details have changed since I last contacted HMRC?

Update your bank details in your online HMRC account before the refund is processed. If the refund is sent to an old account, contact HMRC when ready with your new details. They can redirect the payment, though this may add a few weeks to the process.
