Interessante articolo della BBC: Why expat Americans are giving up their passports

Reasons for giving up your US citizenship aren’t officially listed, but one of the main reasons cited is Fatca – a 2012 law designed to target overseas accounts held by wealthy Americans.
The United States is one of only two countries in the world that has citizenship-based taxation (the other is Eritrea).

As a US citizen you must file a tax return, no matter where you live, and often pay US taxes on top of the tax you already pay in your country of residence – so-called double taxation.

This has been the case in the US since the Civil War in the 19th Century and until recently really only affected the rich. Americans abroad are given a yearly allowance of $106,000 (£73,000) before double taxation kicks in.

But Fatca expands the scope of what can be taxed, and places a burden on foreign banks to identify US citizens among their customers to US tax authorities. The penalty for failing to do so can be as high as 30% of all a bank’s dealings with the USA.

Il commento di una persona in una maling list aggiunge sale alla ferita

as a US citizen living in India, i have similar experiences as filing (filing has no allowance. every adult citizen must file.) taxes in two places is not easy for the following reason:
1. financial years are not synchronised. financial years for the US and India end on December 31st and on March 31st respectively.
2. Indian organisations don’t issue documents such as W9 that help file taxes
3. Indian banks are not well-versed with the US banking laws and they are reluctant to support US citizens
4. every bank account that i am authorised to operate must be reported while filing taxes. for instance, a bank account of an ACM conference that i co-chaired has to be reported even though i cannot use a single penny of it.
