    Brief

    HM Revenue and Customs (HMRC), the UK's tax, payments, and customs authority, seeks contact information to improve collection of unclaimed tax overpayments. In 2025-2026, HMRC issued 4.8 million P800 Tax Calculation overpayment letters, but approximately 1 million remain uncollected. HMRC Payments is looking to reduce this volume by obtaining current customer contact details including mobile numbers, email addresses, and postal addresses. This data will support HMRC's communications strategy, enabling the organization to contact customers and encourage them to collect their entitled overpayments. The opportunity is open to suppliers who can provide accurate, up-to-date contact information to help reconnect HMRC with customers owed refunds.
