Members of the military and certain other
federal employees serving outside the U.S.
have an extra year to buy a principal residence
in the U.S. and qualify for the credit. Thus, an
eligible taxpayer must buy, or enter into a
binding contract to buy,a principal residence on
or before April 30, 2011. If a binding contract
is entered into by that date, the taxpayer has
until June 30, 2011, to close on the purchase.
Members of the uniformed services, members
of the Foreign Service and employees of the
intelligence community are eligible for this
special rule. It applies to any individual (and,
if married, the individual’s spouse) who serves
on qualified official extended duty service
outside of the United States for at least 90
days during the period beginning after Dec.
31, 2008, and ending before May 1, 2010.
