The issue has sparked criticism over outdated payment systems and communication gaps that leave millions unaware of money owed to them.

What is an HMRC Tax Refund?

An HMRC tax refund occurs when you have paid more income tax than required during a tax year and this usually happens due to incorrect tax codes, job changes, pension payments or overlapping employment. Once identified, HM Revenue and Customs returns the excess amount through bank transfer or cheque.

• Incorrect tax codes issued by employers or HMRC
• Switching jobs and receiving overlapping payments
• Starting pension payments earlier than expected
• Receiving jobseeker's allowance or employment support payments

These scenarios frequently lead to excess deductions during the tax year.
