Guidance Notes

The main update changes contained in the Guidance Notes are set out in the Industry Advisory and include clarification on matters such as nil returns and private trust companies.  

The Guidance Notes are considered to be a dynamic document which has been under review over the past several months by the Working Group which comprises members of the private and public sector in Cayman.  As the implementation of FATCA continues and with the pending introduction of the OECD Common Reporting Standard, additional or updated versions of the Guidance Notes can be expected.
