(b) Individuals in missing status For purposes of this section, in the case of an individual who was in a missing status within the meaning of section 6013(f)(3)(A), the date of his death shall be treated as being not earlier than the date on which a determination of his death is made under section 556 of title 37 of the United States Code. Except in the case of the combat zone designated for purposes of the Vietnam conflict, the preceding sentence shall not cause subsection (a)(1) to apply for any taxable year beginning more than 2 years after the date designated under section 112 as the date of termination of combatant activities in a combat zone. (c) Certain military or civilian employees of the United States dying as a result of injuries (1) In general In the case of any individual who dies while a military or civilian employee of the United States, if such death occurs as a result of wounds or injury which was incurred while the individual was a military or civilian employee of the United States and which was incurred in a terroristic or military action, any tax imposed by this subtitle shall not apply— (A) with respect to the taxable year in which falls the date of his death, and (B) with respect to any prior taxable year in the period beginning with the last taxable year ending before the taxable year in which the wounds or injury were incurred. (2) Terroristic or military action For purposes of paragraph (1), the term “terroristic or military action” means— (A) any terroristic activity which a preponderance of the evidence indicates was directed against the United States or any of its allies, and (B) any military action involving the Armed Forces of the United States and resulting from violence or aggression against the United States or any of its allies (or threat thereof).

(2) $10,000 minimum benefit If, but for this paragraph, the amount of tax not imposed by paragraph (1) with respect to a specified terrorist victim is less than $10,000, then such victim shall be treated as having made a payment against the tax imposed by this chapter for such victim’s last taxable year in an amount equal to the excess of $10,000 over the amount of tax not so imposed. (3) Taxation of certain benefits Subject to such rules as the Secretary may prescribe, paragraph (1) shall not apply to the amount of any tax imposed by this chapter which would be computed by only taking into account the items of income, gain, or other amounts attributable to— (A) deferred compensation which would have been payable after death if the individual had died other than as a specified terrorist victim, or (B) amounts payable in the taxable year which would not have been payable in such taxable year but for an action taken after September 11, 2001 . (4) Specified terrorist victim For purposes of this subsection, the term “specified terrorist victim” means any decedent— (A) who dies as a result of wounds or injury incurred as a result of the terrorist attacks against the United States on April 19, 1995 , or September 11, 2001 , or (B) who dies as a result of illness incurred as a result of an attack involving anthrax occurring on or after September 11, 2001 , and before January 1, 2002 . Such term shall not include any individual identified by the Attorney General to have been a participant or conspirator in any such attack or a representative of such an individual. (5) Relief with respect to astronauts The provisions of this subsection shall apply to any astronaut whose death occurs in the line of duty, except that paragraph (3)(B) shall be applied by using the date of the death of the astronaut rather than September 11, 2001 .
