This will be an issue for every expat going forward
This is not a US IRS issue, it is an issue for everyone else.
This is the first step in the rest of the world moving towards a similar system to how the US currently taxes its expats.
This step is the data collection point and therefore we are probably a few years from a common worldwide standard.
It is coming but just not this year.
The data that is available is specific to each pilot IE your home country will be able to find out how much a particular expat is earning down to the last penny.
Someone stated that this is available on the EK website, well yes and no.
What is there is a general figure and not exactly what the individual earns.
Just beaware of this as the years roll on as they do here inthe sandpit.
