Okay, thanks folks.
I think we should be okay then, I was scared we were going to be hit for 18-28% of our life savings which is effectively what the house proceeds will constitute.
Guya, I do qualify as a long term green card holder, been here 9 years now but thankfully, even together, we don't come close to these figures. And hubby has no intentions of revoking his citizenship.:
"Under the mark-to-market exit tax regime, an expatriating individual who has a net worth of at least US$2 million or an average income tax liability for the previous five years of at least US$145,000 (2010 figure, adjusted annually for inflation), or who fails to certify as to compliance with all US federal tax obligations for the previous five years, will be deemed to have sold their worldwide assets for fair market value on the day before expatriation. This “covered expatriate” (CE) will pay tax on any resulting net gains in excess of an inflation-adjusted exclusion amount, currently US$627,000."
