Several firms based in the UK, Switzerland and other places specialize in offering US expats and those with US links access to financial services, which can be unusually complicated because of the US worldwide tax code.

Tanager Wealth Management, a London-based wealth management firm specializing in US-linked clients and those with transatlantic financial affairs, has formed a new pact with Financial Software (FSL). 

Under this arrangement, Tanager obtains enhanced tax reporting services by using Financial Software’s CGiX set of digital tools.

The CGiX suite of functionalities includes capital gains tax reporting, excess reportable income reporting and “what-if” modeling. 

Tanager can use CGiX to help it import financial data from international custodians to produce reports, so that Tanager clients’ accountants can translate income and gains for UK tax purposes and report clients’ UK tax liabilities to HMRC. 

The need for such a service is particularly acute, Tanager said, because US-connected clients have particularly complex reporting needs – the US operates a worldwide tax code, contrasting with that of most industrialized nations which use a territorial system.

FSL, which has been providing services since 1994, is part of Industrial Thought Ltd, the parent company for a group of companies in the field of investment taxation, financial data, and related consultancy services. 

Several UK-based firms specialize in offering US expats and those with US links access to financial services, which can be unusually complicated because of the US tax code. Examples include Schroders, MASECO and London & Capital. In Switzerland, firms that have SEC registration, enabling them to serve expats, include REYL, Vontobel and Hyposwiss Advisors.
