Recent headlines have highlighted the names of wealthy individuals who have given up their U.S. citizenship, ostensibly to save taxes.

Remember Eduardo Saverin, the Facebook founder who renounced his U.S. citizenship on the eve of Facebook’s now legendary IPO? More recently, it is Denise Rich, socialite, songwriter and ex-wife of a pardoned billionaire, whose name has appeared on a list of those who have given up their U.S. citizenship.

Does this door swing both ways? Does anyone ever come to the United States to save taxes? And if they did, would the story make the headlines?

Consider the case of Steve Nash.

Yes, sports fans, that’s point guard Steve Nash, lately of the Phoenix Suns, with annual income reportedly in excess of $10 million. Nash is a Canadian citizen, born in South Africa and living in the United States.

Recently Nash rejected an offer from the Toronto Raptors, electing instead to sign with the Los Angeles Lakers. Was Nash’s decision based on a desire to play with Kobe Bryant or a preference for paying income taxes to the United States?

According to Robert Raiola, known on Twitter as Sports Tax Man, Nash may have made his decision to reject theRaptor’s offer in favor of Los Angeles largely for tax reasons. According to Raiola, who does not work for Nash, the top marginal tax rate in Ontario, where the Raptors play their home games, is 48 percent in 2012 and will rise to 49.5 percent in 2013.

Compared to the top U.S. tax rate of 35 percent in 2012 and perhaps 40.5 percent in 2013, Raiola surmises that Nash would have needed a much greater financial incentive to entice him back to his Canadian roots – eh.
