Facebook Co-Founder Saverin Gives Up U.S. Citizenship Before IPO

Eduardo Saverin, the billionaire co- founder of Facebook Inc. (FB), renounced his U.S. citizenship before an initial public offering that values the social network at as much as $96 billion, a move that may reduce his tax bill.

Facebook plans to raise as much as $11.8 billion through the IPO, the biggest in history for an Internet company. Saverin’s stake is about 4 percent, according to the website Who Owns Facebook. At the high end of the IPO valuation, that would be worth about $3.84 billion. His holdings aren’t listed in Facebook’s regulatory filings.

Saverin, 30, joins a growing number of people giving up U.S. citizenship, a move that can trim their tax liabilities in that country. The Brazilian-born resident of Singapore is one of several people who helped Mark Zuckerberg start Facebook in a Harvard University dorm and stand to reap billions of dollars after the world’s largest social network holds its IPO.

“Eduardo recently found it more practical to become a resident of Singapore since he plans to live there for an indefinite period of time,” said Tom Goodman, a spokesman for Saverin, in an e-mailed statement.
