    Brief

    HM Revenue and Customs (HMRC) seeks contact information to improve collection of unclaimed tax overpayments. HMRC issued 4.8 million P800 Tax Calculation overpayment letters in 2025 to 2026, with approximately 1 million remaining uncollected. HMRC Payments requires verified and up-to-date customer contact details including mobile numbers, email addresses, and postal addresses to enable targeted communications and encourage customers to claim their overpayments. This data will support HMRC's customer outreach strategy to reduce the volume of uncollected repayments and improve payment collection efficiency.
