...The National Taxpayer Advocate's Office, part of the IRS, released a report in December that details the difficulties of filing taxes from overseas. It cites heavy paperwork, a lack of online filing options and a dearth of local and foreign-language resources.
For those wishing to legally escape the filing requirements, the only way is to formally renounce their U.S. citizenship. Last year, IRS records show that at least 1,788 people did, and that's likely an underestimate. The IRS publishes in the Federal Register the names of those who give up their citizenship, and some who renounced say they haven't seen their name on the list yet. ...
...On April 7, 2011, Peter Dunn raised his right hand before a U.S. consular officer in Toronto and swore that he understood the consequences of giving up his U.S. citizenship. Dunn, a dual U.S.-Canadian citizen who has lived outside the United States since 1986, says he renounced because he felt American citizenship had become more of a liability than a privilege.
As an American, Dunn had to file tax returns and report all of his bank accounts - even joint accounts and his Canadian retirement fund. If he didn't, he would be breaking U.S. law and could face penalties of up to $100,000 or 50 percent of his undeclared accounts, whichever is larger. Dunn says he was tired of tracking IRS policy changes, and he had no intention of returning to the United States. Renouncing his citizenship, as he puts it, was "a no-brainer."
