HMRC's April 2023 ,one-to-many, letter campaign targets businesses using Electronic Sales Suppression (ESS) tools, such as software, to deliberately manipulate electronic sales records and hide the value of individual transactions.

ESS tools artificially reduce the recorded turnover of the business, evading tax, while producing a credible audit trail which appears correct and complete.

The one-to-many letters now being issued indicate that HMRC have information suggesting that the recipient has misused their till system. Affected taxpayers are invited to make a disclosure within 30 days. 

  • Disclosures may be made via the ‘make a disclosure about misusing your till system’ service on GOV.UK.
  • Where businesses that have used ESS tools do not make a disclosure, HMRC may open an investigation or issue an assessment.
  • Businesses in receipt of a letter that do not have undeclared sales should email HMRC accordingly, using the details given in the letter. 

The campaign is expected to continue for at least a year.
