How to respond to an HMRC “one to many” or nudge letter based on data from overseas tax authorities, online selling platforms or cryptoasset exchanges – checking the position, the Certificate of Tax Position, explaining that everything has been declared, or moving to a disclosure – with reply letters.
Letters to HMRC & personal tax
Replying to an HMRC “Nudge” or Campaign Letter – Offshore, Online Platforms and Cryptoassets
About this document
HMRC receives data from overseas tax authorities, online platforms (under the digital platform reporting rules from 2024) and, from 2026, cryptoasset service providers. It uses this data to send “nudge” letters asking taxpayers to check their tax affairs. These letters are not formal enquiries, but they should never be ignored.
The document is laid out in the sections below. Each one comes with a plain-English guidance note explaining what it does and what to change.
Our templates are professionally structured starting points for UK businesses, not legal advice. For anything complex, unusual or high-value, have your final version checked by a solicitor.
