The letters are being sent to taxpayers who HMRC believes may be impacted by the changes to how foreign income and gains are taxed. With the revised rules now in force, affected individuals may need to reassess how their overseas income is reported and taxed. Recipients are encouraged to consider how the new regime applies to their circumstances and to take action where necessary. This may include reviewing existing arrangements or seeking advice to ensure compliance under the updated rules.

Although the letters do not constitute a formal enquiry, they indicate that HMRC is actively identifying individuals within scope of the changes. As with other “one-to-many” communications, they are intended to prompt voluntary review and early action. For affected individuals, the key point is to treat the letter as a prompt to reassess their position under the new rules rather than ignore it. Addressing any issues early can help avoid complications or penalties later.
