Here are the three most relevant developments in the world of structured reporting we became aware of in the course of last week.

1  Hong Kong prepares for digital tax reporting using inline XBRL

The Hong Kong Inland Revenue Department (IRD) looks set to launch Inline XBRL-based digital tax reporting for business within the next 18 months.

3  EIOPA set out a forward looking digital transformation strategy
