UK Privacy and Reporting

What HMRC and other authorities receive about an offshore bond held by a UK resident, and what stays private. The articles cover the Common Reporting Standard figures the insurer sends every year, the chargeable event certificate and how to read each figure on it, which Self Assessment pages a gain goes on, the Trust Registration Service for a bond held in trust, and who else, from a divorce court to an executor, can see the policy and who cannot.
